5 * Removed hacks for backward compatibility with Linux libc5,
6 which were breaking newer non-glibc Linux systems. Thanks
9 * Display VirtIO vendor-specific capability. Patch by Gerd
12 * Fixed memory leak in name cache.
14 2014-11-10 Martin Mares <mj@ucw.cz>
17 (celebrating a one-year anniversary of the previous version :))
19 * Device names exported by BIOS are displayed on Linux.
21 * On Linux systems, HWDB is used to look up device names
22 when our ID database gives no match. (More precisely,
23 HWDB is consulted after local pci.ids, but before using
24 network to query online pci.ids.) Thanks to Tom Gundersen
25 for the initial patch.
27 * Added experimental back-end for OS X / Darwin. Thanks to
28 Richard Yao for providing it.
30 * Filters now support matching by device class. Original
31 patch by Matthew Wilcox, wrappers for ABI compatibility
34 * Interrupt Pin and Interrupt Line registers are displayed
35 for bridge devices, too.
37 * Several portability bugs have been fixed.
39 * Several typos have been fixed. Also, use of questionable
40 constructs in man pages has been reduced.
42 * PCIe link capabilities now include the ASPMOptComp bit.
44 * The "CRS Software Visibility" bit is now decoded properly.
46 * Updated pci.ids to the current snapshot of the database.
48 2013-11-10 Martin Mares <mj@ucw.cz>
52 * CardBus bridge capabilities are displayed.
54 * PCIe L1 PM substates are decoded.
56 * Various bugs were fixed in decoding of PCIe capabilities.
58 * The sysfs back-end does not spit out unnecessary warnings when
59 empty slots report only a partial device address. This actually
60 happens on IBM pSeries.
62 * Updated pci.ids to the today's snapshot of the database.
64 2013-04-19 Martin Mares <mj@ucw.cz>
68 * On newer Linux systems, we use libkmod to look up kernel modules
69 (modules.pcimap no longer exists). To facilitate this, libpci
70 is able to look up module aliases in sysfs.
72 * Various minor bug fixes.
74 * Updated pci.ids to the today's snapshot of the database.
76 2012-06-25 Martin Mares <mj@ucw.cz>
80 * Decoding of LTR/OBFF in PCIe capabilities.
82 * Various minor bug fixes.
84 * Updated pci.ids to the today's snapshot of the database.
86 2012-01-14 Martin Mares <mj@ucw.cz>
92 * Wherever we mention the PCI ID database, we now refer to
93 http://pci-ids.ucw.cz/ and the sf.net site is mentioned only
94 as a mirror. This includes update-pciids.
96 * Decode PCIe Gen 3 speeds and link status fields.
98 * Various minor bug fixes.
100 * Updated pci.ids to the today's snapshot of the database.
102 2011-10-02 Martin Mares <mj@ucw.cz>
106 * More capabilities: Transaction Processing Hints, Latency Tolerance
107 Reporting. Thanks to Jesse Barnes.
109 * Added BeOS and Haiku ports. Contributed by Francois Revol.
111 * pciutils.pc now uses Libs.private properly.
113 * When we format a name and it does not fit in the buffer, we truncate
114 it instead of returning "buffer too small" instead. This works on all
115 platforms with sane (i.e., C99-compatible) snprintf().
117 * Various minor bug fixes.
119 * Updated pci.ids to the today's snapshot of the database.
121 2010-01-31 Martin Mares <mj@ucw.cz>
125 * Minor improvements and bug fixes in decoding of the Virtual Channel
128 2010-01-24 Martin Mares <mj@ucw.cz>
132 * More capabilities decoded: Virtual Channel (except arbitration
133 tables), Root Complex Link, Vendor-Specific (header only), SATA HBA.
135 * All extended capabilities have their version displayed (-vv or more).
137 2010-01-19 Martin Mares <mj@ucw.cz>
141 * Updated pci.ids to the today's snapshot of the database.
143 * When scanning extended capabilities, properly mask the lowest 2 bits,
144 which are currently reserved. This avoids unaligned access errors on
145 broken hardware (see tests/broken-ecaps).
147 * Large bar sizes are displayed in human-readable format (with units).
148 Thanks to Matthew Wilcox.
150 * Physical slot information is displayed correctly for multi-function cards.
151 Fixed by Matthew Wilcox.
153 * Fixed a couple of typos everywhere.
155 * Library: Fixed bugs in freeing of capabilities.
157 * Windows back-end compiles again.
159 2009-08-14 Martin Mares <mj@ucw.cz>
162 (sorry that I have missed 22/7 and released it later :-))
164 * Updated pci.ids to the today's snapshot of the database.
166 * Fixed memory and file descriptor leak in the dump back-end.
168 * The SR-IOV capability decoder now prints the VF BAR's.
169 Patch by Chris Wright, cleaned up by me.
171 * On request of certain company's lawyers, we now include a copy
172 of the GPL with our package. It seems that the pciutils are getting
173 mature if the most important bug of the month was this one ;-)
175 2009-07-04 Martin Mares <mj@ucw.cz>
179 * Updated pci.ids to the current snapshot of the database.
181 * The VPD parser now reports unknown and vendor-defined items
182 properly. It also stops on any item in unknown format, avoiding long
183 output on bogus VPD data. Thanks to Ben Hutchings and Matthew Wilcox.
185 * The MSI-X table size now matches the spec. Thanks to Michael S.
188 * The Power Management capability now includes the soft reset bit.
191 * Decoding of the Advanced Features capability has been added.
194 * The whole package compiles on GNU/kFreeBSD again.
196 The following patches have been contributed by Matthew Wilcox:
198 * The procfs back-end is able to cope with /proc/bus/pci
199 containing names with domains, which occur on sparc64 and
200 possibly other architectures due to a kernel bug.
202 * The sysfs back-end no longer complains when a slot address
203 is missing, which happens with old versions of Linux fakephp.
205 * The Device Serial Number capability is printed in the right
208 * The MSI and MSI-X capabilities are printed in a prettier way.
210 * The tree output mode (`lspci -t') shows domain numbers only
211 at the root, which makes the output more compact.
213 * Updated documentation on the bus mapping mode (`lspci -M').
215 2009-02-01 Martin Mares <mj@ucw.cz>
219 * Fixed another silly bug in the command-line parser of setpci.
221 2009-01-30 Martin Mares <mj@ucw.cz>
225 * Updated pci.ids to the current snapshot of the database.
227 * The configure script now sets LC_ALL to avoid being fooled by
228 locale-dependent behavior of `tr'.
230 * The command-line parser of setpci did sometimes segfault on invalid
231 input. Thanks to Andreas Wiese for a fix.
233 2009-01-18 Martin Mares <mj@ucw.cz>
237 * Updated pci.ids to the current snapshot of the database.
239 * The Cygwin backend now works on Windows Vista. Thanks to Jonathan
242 * Fixed a bug in decoding of the SR-IOV capability. Patch by Yu Zhao.
244 * Details of some PCIe capabilities are displayed only with -vv.
246 * When a BAR is reported by the OS, but not by the device (i.e.,
247 it is marked as [virtual] in lspci), the [disabled] flag is
248 suppressed, because it does not make sense in such cases.
251 2008-12-13 Martin Mares <mj@ucw.cz>
253 * The source code of lspci has been split to multiple files, hopefully
254 making it easier to maintain.
256 * The library and lspci now know about physical slot names. So far,
257 they are provided by the sysfs back-end only. Thanks go to Alex Chiang.
259 * When a device has the VPD (Vital Product Data) capability and the
260 VPD data are supplied by the OS, they are decoded and printed in the
261 verbose mode. This currently works only on Linux with the sysfs
262 back-end. Thanks to Ben Hutchings of Solarflare for the patch.
264 * `setpci --version' now works properly.
266 * `setpci --dumpregs' prints a table of all known names of
267 registers and capabilities. This replaces the table of registers
268 in the setpci man page.
270 * The dry-run mode of setpci gives better feedback.
272 * The setpci utility is now able to address registers stored in PCI
273 capabilities (actually it allows a more general form of relative
276 * The library has gained functions for working with PCI capabilities.
278 * Address Translation Services capability is now decoded. Patch by
281 2008-11-09 Martin Mares <mj@ucw.cz>
285 * `lspci -k' now displays the subsystem ID, too. This makes `-k'
286 show everything needed to identify the device and the available
287 drivers, which was called for by many users.
289 * Fixed spelling of MSI. Patch by Matthew Wilcox.
291 * Better support for cross-compilation. Thanks to Alon Bar-Lev
294 * Fixed printing of the AER capability. Patch by Max Asbock.
296 * HT 1.02 capabilities are decoded as HT 1.03. Suggested by
297 Carl-Daniel Hailfinger.
299 * Fixed Cygwin build. Thanks to Steve Elliott for reporting the bug.
301 * Updated pci.ids to the current snapshot of the database.
303 2008-09-19 Martin Mares <mj@ucw.cz>
307 * Fixed a minor bug in the configure script, which caused warnings
308 about redefinition of symbols during compilation.
310 2008-09-11 Martin Mares <mj@ucw.cz>
314 * Updated pci.ids to the most recent snapshot.
316 * Added a Cygwin port. Patch by Christopher Voltz, ported to the
317 current tree by Martin Mares.
319 * Worked around compatibility problems with various default settings
320 of wget (we have to set --no-timestamping explicitly). Thanks to Ville
321 Skytta for pointing that out.
323 * Fixed printing of MSI capabilities. Thanks to Matthew Wilcox for
326 * Added decoding of several PCI-X capabilities: device/link/slot 2,
327 Advanced Error Reporting, Access Control Services, Alternative Routing-ID,
328 Single Root I/O Virtualization. Thanks to Yu Zhao for patches.
330 * Fixed bug in filters which caused them to refuse vendor/device ID 0xffff.
332 * README: The linux-pci mailing list has moved to linux-pci@vger.kernel.org.
334 * Fixed several build problems: builds without PCI_USE_DNS on Linux
335 and with PCI_USE_DNS on Solaris and *BSD. Static library mode also
336 compiles again on old versions of GCC.
338 2008-04-10 Martin Mares <mj@ucw.cz>
342 * Updated API and ABI version.
344 2008-02-20 Martin Mares <mj@ucw.cz>
346 * Released as 2.99.1-alpha2.
348 * Changed the default domain for the DNS resolver.
350 2008-02-18 Martin Mares <mj@ucw.cz>
352 * Released as 2.99.1-alpha1.
354 * The makefile system has been reworked. All configuration settings
355 are now passed to the configure script in environment variables,
356 allowing for easy tweaking in the top-level Makefile. All control
357 knobs are now described in the README.
359 * The libpci can be built as a shared library with properly restricted
360 symbol exports. Use `make SHARED=yes' to enable that or `make SHARED=local'
361 for a local testing build (with hardwired paths to the library, so that
362 it does not need installation).
364 * The example program has been moved from lib/example.c to the top-level
365 directory, because it should be built exactly as the other utilities
366 are. It has been also improved slightly to educate better.
368 * The i386-ports method is enabled on Linux/x86_64 as well.
370 2008-02-13 Martin Mares <mj@ucw.cz>
372 * Released as 2.2.10-net2.
374 * Support for resolving of PCI ID's using DNS together with a local
375 cache of resolved entries has been added. See the `-q' and `-Q' options
378 * The library now has a generic system of settable parameters, which
379 also include settings of the DNS resolver and cache. An `-O' option
380 has been added to lspci and setpci to allow setting of these options.
382 * Configuration of the access methods are now specified by the new
383 parameter system, replacing the pci_access->method_params array.
385 * Access methods now also have sensible names and help texts and it
386 is possible to look up method ID by a name.
388 * An `-A' switch has been added to both lspci and setpci, allowing to
389 select an arbitrary access method. The `-P' switch (configure proc
390 backend) has been removed as it is no longer needed and I do not know
393 * Several source files have been split for better maintainability
394 (most notably the resolving of ID's).
396 * Man pages and help texts have been updated. A new man page `pcilib(7)'
397 has been added and description of library options has been moved there.
399 * When an unknown device ID is encountered, we print `Device <id>'
400 instead of `Unknown device <id>'. It uses less space and it also
401 should reduce the number of inexperienced users complaining that
402 the device is not supported by the OS. To lookup up OS drivers,
405 * PCI_LIB_VERSION has been bumped to 0x020299.
407 * Makefile: stripping of the binaries during installation can be
408 overridden by the STRIP variable.
410 * lib/types.h: We use the integer types from <stdint.h> if the
411 compiler claims C99 support.
413 2008-02-11 Martin Mares <mj@ucw.cz>
415 * Released as 2.2.10.
417 * lspci.c, setpci.c: Cleaned up the list of options.
419 * lib/names.c: Fix displaying of errors reported by zlib.
420 Previously, the buffer containing the error message had
421 been deallocated by gzclose() before the message was printed.
423 2008-01-07 Martin Mares <mj@ucw.cz>
425 * update-pciids.sh: Added quiet mode (-q). Clean up uncompressed
426 files left by previous versions of the pciutils. Patch by Mike
429 * update-pciids.man: Mention the -q switch.
431 2007-11-29 Martin Mares <mj@ucw.cz>
433 * lib/dump.c: Squashed compiler warnings about code with
434 no effect (there really were surplus *'s).
436 2007-11-06 Martin Mares <mj@ucw.cz>
440 * lspci.c: Added a new switch `-k' which requests printing
441 of information on kernel drivers attached to each device
442 and on kernel modules reporting the ability to handle the
443 device. So far, this is supported only on Linux with the
444 sysfs back-end, so it is implemented internally in the lspci
445 instead of the libpci. Thanks to Anicka <anicka@anicka.net>
448 2007-10-19 Martin Mares <mj@ucw.cz>
450 * Makefile, lib/Makefile: Moved -lz from LDFLAGS to LDLIBS.
451 Also added an explicit pattern rule for linking to make sure
452 that LDLIBS is used on all platforms. Thanks to Dan Nicholson
455 2007-10-19 Martin Mares <mj@ucw.cz>
459 * pci.ids: Revised class codes to match Conventional PCI 3.0 specs.
460 Added a couple of new ones, renumbered `ADMA continuous operation'
461 prog-if to 0x30 (even the old SATA Class Code ECN doesn't mention
462 0x40) and renumbered the satellite communication controllers.
464 * lib/header.h: Include `PCI hot-plug' and `Secure device'
465 capabilities from PCI 3.0 specs. Also added `SATA HBA' and
466 `Advanced features' caps from various ECN's.
468 * lspci.c: All known capabilities have at least their name displayed
469 now. When we are unable to decode them completely, we signalize it
472 * lspci.man: Document `<?>' and also mention that extended config
473 space is currently available only with the linux_sysfs back-end.
475 * lspci.c: Decode the Debug port capability (per EHCI 0.96 spec).
477 * lspci.c: Big code cleanup: re-arranged functions in the code,
478 renamed everything related to capabilities to cap_* and
479 all options except verbose to opt_*.
481 2007-10-14 Martin Mares <mj@ucw.cz>
483 * lib/[fno]bsd-*: Removed extraneous braces.
485 2007-10-12 Martin Mares <mj@ucw.cz>
487 * Capability loop detection introduced 2.2.7 did not work
488 properly with extended capabilities. Fixed.
490 2007-10-05 Martin Mares <mj@ucw.cz>
494 * lspci.c (show_caps, show_ext_caps): Detect and report loops in
497 * lspci.c, lib/header.h: Finished decoding of the PCI Express
498 capability. The extended capabilities remain undecoded for now,
499 but at least the list of them has been updated to reflect the
500 current PCI Express 2.0 spec.
502 * lspci.c, lib/header.h: Decode new bits of traditional registers
503 as defined by PCIE / PCI-X. This includes discard timers in the bridge
504 control register and INTx enable/status in device control/status
507 * lib/fbsd-device.c: Support domains on new FreeBSD's. Contributed
510 2007-09-12 Hasso Tepper <hasso@estpak.ee>
512 * Extended the fbsd-device backend to run on Dragonfly BSD.
514 * lspci.c: alloca() is declared in <stdlib.h> on BSD's, not <alloca.h>.
516 2007-09-03 Martin Mares <mj@ucw.cz>
518 * Resurrected the Windows port, including cross-compilation by MinGW.
519 Patch by Samuel Bronson <naesten@gmail.com>.
521 2007-08-31 Martin Mares <mj@ucw.cz>
523 * Makefile, lib/Makefile: `ar' and `ranlib' can be overriden to allow
526 2007-08-27 Martin Mares <mj@ucw.cz>
528 * lib/names.c (pci_open): When calling gzopen(), use "rb" file mode
529 instead of "r". This is needed on DOS systems, where this function
530 somewhat illogically uses the binary flag for the compressed file
531 instead of the decompressed stream inside, where binariness really
534 2007-08-14 Martin Mares <mj@ucw.cz>
536 * lspci.c (show_ht): Added decoding of Hypertransport MSI mapping capability,
537 based on a patch by Jason Gunthorpe.
539 * tests/cap-MSI-mapping: Added a test case. I plan to add test cases
540 (which are dumps of config space) for all new features.
542 2007-06-20 Martin Mares <mj@ucw.cz>
546 * Makefile: Added an "install-lib" target. Thanks to Dan Nicholson
549 * Makefile, lib/Makefile: Generate and install pkg-config file
550 for libpci. Again by Dan Nicholson.
552 2007-06-20 Thomas Schwinge <tschwinge@gnu.org>
554 * lib/i386-io-hurd.h: Rewritten for new Hurd kernels.
556 2007-05-04 Martin Mares <mj@ucw.cz>
560 * pci.ids: Updated to the current snapshot of the database.
562 2007-02-14 Martin Mares <mj@ucw.cz>
564 * lspci.c (show_express): Added PCI/PCI-X to PCI-Express Bridge type.
565 Patch by Mark Glines.
567 2007-02-09 Martin Mares <mj@ucw.cz>
569 * pci.ids: Updated to the current snapshot of the database.
571 2007-02-06 Martin Mares <mj@ucw.cz>
573 * Replaced bzero() by memset() everywhere, it's better to lose a tiny
574 bit of readability than maintain hacks to make it work on various systems.
576 * lib/configure: tr on Solaris is a bit weird and it requires `[A-Z]'
577 instead of `A-Z'. Fortunately, the extra brackets don't hurt otherwise.
579 * lib/types.h, lib/configure: Solaris should use <stdint.h> to get precise
582 2007-02-04 Martin Mares <mj@ucw.cz>
584 * lspci.c: alloca() needs <alloca.h>.
586 2006-09-17 Martin Mares <mj@ucw.cz>
588 * lib/dump.c: Fixed a couple of bugs in the dump backend which caused
589 devices with domains or with extended config space to be read incorrectly.
590 Also, dumps with partial lines are allowed now.
592 2006-09-10 Martin Mares <mj@ucw.cz>
594 * pci.ids: Updated to the current database snapshot.
596 * lspci.c (scan_device): If an error occurs when reading the standard config
597 header of a device, report it and ignore the device and return with exit
600 2006-09-09 Martin Mares <mj@ucw.cz>
604 * maint/release: Remind the maintainer about the current PCI_LIB_VERSION.
606 * lib/pci.h: Updated PCI_LIB_VERSION.
608 * lspci.c (show_machine): In the `-m' mode, do proper shell escaping
609 if the fields printed contain quotes or backslashes.
611 * lspci.c (show_machine): Added a `-vmm' mode, which removes the misuse
612 of the `Device' tag for two different purposes.
614 * Makefile: Moved all system-dependent decisions to lib/configure,
615 since config.mk is included in the top-level Makefile anyway.
617 * lib/configure: When configuring for Linux, ignore the kernel version
618 and always build all access methods.
620 * Makefile (CFLAGS): Removed -Winline, it's not needed and triggers
621 at many non-interesting places with gcc 3.4.
623 * Whitespace cleanup of all source files.
625 * The pci.ids file can be stored compressed if zlib is available.
626 Added transparent decompression to lib/names.c, modified update-pciids.sh
627 to keep the file compressed if applicable, updated Makefiles.
628 Based on a patch by Matthew Wilcox, but all the bugs are mine.
630 * Makefile, README: Allow installation to be done to a different directory
631 from the one we will eventually be placed in by setting DESTDIR.
632 Patch by Matthew Wilcox.
634 * Added .gitignore files.
636 * Makefile (clean): Clean *.orig, too.
638 * Cleaned up usage of `char' and `byte'.
640 * lib/header.h: PCI_CLASS_DOCKING_OTHER should be 0x0a80, not 0x0a01.
642 * lib/header.h: Added PCI_CLASS_xxx constants for all classes currently
643 defined in the pci.ids file.
645 2006-08-01 Martin Mares <mj@ucw.cz>
647 * lib/i386-io-hurd.h: Fixed a silly typo.
649 2006-07-30 Martin Mares <mj@ucw.cz>
651 * lib/Makefile: Added a missing rule for obsd-device.o.
653 * lspci.c, lib/header.h: Added support for MSI per-vector masking.
654 Contributed by Petr Vandrovec.
656 * lspci.c, lib/header.h: Added support for the `bridge subsystem ID'
657 capability. Contributed by Petr Vandrovec.
659 * lspci.c (show_htype1): Fixed bug in printing of 64-bit prefetchable
660 memory windows. Fix by Petr Vandrovec.
662 * maint/release.pm: Exclude .git directory from releases.
664 * lib/i386-ports.c, lib/i386-io-*: Report failures during port access
665 initialization by a->warn() instead of calling printf() or perror()
668 * lib/i386-ports.c, lib/i386-io-*: Moved the logic which keeps track of
669 the port access state to generic code.
671 * lib/i386-io-hurd.h: Ask the kernel for I/O port access appropriately.
672 Contributed by Thomas Schwinge and Samuel Thibault.
674 * lib/i386-ports.c: Define _GNU_SOURCE, it's needed by the Hurd module.
676 * lib/header.h: Whitespace cleanups.
678 * lib/i386-io-windows.h: Fixed indentation and spelling.
680 * README.Windows: Mention that WinIO.dll is needed and where to get it.
682 2006-06-27 Martin Mares <mj@ucw.cz>
684 * lib/Makefile, Makefile: Added rules for building and cleaning the example.
686 * lib/example.c: Show how to use PCI_FILL_CLASS and used another register
687 for demonstrating the config space accesses. The example is still very
690 * lib/pci.h, lib/generic.c: Added PCI_FILL_CLASS.
692 * lib/sysfs.c: Fetch device ID and class from sysfs, because they can
693 be modified by kernel fixups.
695 * lspci.c: Use PCI_FILL_CLASS. Thanks to Matthew Willcox for the patch.
697 2006-06-03 Martin Mares <mj@ucw.cz>
699 * lspci.c: Introduced the -nn switch. Thanks to David N. Welton
702 * lib/names.c (pci_lookup_name): Introduced PCI_LOOKUP_MIXED and
703 cleaned up the name selection code.
705 * lib/names.c (pci_lookup_name): If PCI_LOOKUP_NO_NUMBERS is given,
706 pci_access->numeric_ids is ignored.
708 * lib/names.c (pci_lookup_name): When class is identified and
709 subclass isn't, display class name and subclass number.
711 2006-05-31 Martin Mares <mj@ucw.cz>
713 * setpci.c (main): Don't crash when an invalid width is specified.
715 * lspci.c, setpci.c, common.c: die() now uses the right program
716 name when printing an error message.
718 2006-05-19 Martin Mares <mj@ucw.cz>
720 * README: Mention the public GIT tree.
722 * README: Updated the list of ports.
724 2006-05-10 Martin Mares <mj@ucw.cz>
726 * lib/configure, lib/fbsd-device.c: Added support for GNU/kFreeBSD.
727 Thanks to Petr Salinger for the patch.
729 2006-05-05 Martin Mares <mj@ucw.cz>
733 * lspci.c (scan_device): The -D switch didn't work as intended
736 2006-05-05 Martin Mares <mj@ucw.cz>
740 * pci.ids: Updated to the current database snapshot.
742 * lib/obsd-device.c (and other files in lib/*): Added OpenBSD
743 interface by Matthieu Herrb <matthieu.herrb@laas.fr>, based on
744 the existing FreeBSD interface.
746 * Moved pciutils to a GIT repository, which now contains merged
747 history from both CVS and Arch. Good bye, TLA!
749 2006-03-21 Martin Mares <mj@ucw.cz>
751 * lspci.c (show_slot_name): Avoid the previous changes in default
752 display of domain name when in machine-readable mode. However, `-D'
753 forces domain display even there.
755 * lspci.man: Added a warning on -m being the only format, which is
756 guaranteed to be stable between lspci versions.
758 2006-03-13 Martin Mares <mj@ucw.cz>
760 * lspci.man: Documented the -D switch.
762 * lspci.c (show_slot_name, scan_device): If there are multiple PCI
763 domains or if the `-D' switch is used, show the domain number for
766 * lspci.c (show_verbose): Report cache line size in bytes.
768 * update-pciids.sh: Use curl if available. Patch by Matthew Wilcox.
770 2006-01-04 Martin Mares <mj@ucw.cz>
772 * lspci.c (show_express_link): Fixed decoding of link status register.
773 Thanks to Roland Dreier for his report.
775 2005-12-12 Martin Mares <mj@ucw.cz>
777 * lib/nbsd-libpci.c: If libpci is used by an ordinary user, allow
778 at least read-only access. Patch by Pavel Celeda <celeda@liberouter.org>.
780 * Makefile: Corrected library path on NetBSD.
782 2005-11-26 Martin Mares <mj@ucw.cz>
786 * lspci.c (show_machine): Subsystem vendors were printed incorrectly
787 in machine-readable modes. Thanks to Pavel Celeda for a bug report.
789 2005-10-11 Martin Mares <mj@ucw.cz>
791 * lspci.c (new_bus): Fixed a memory leak. Thanks to Paul Sangree for reporting it.
793 2005-09-21 Martin Mares <mj@ucw.cz>
797 * pci.ids: Updated copyright header.
799 * lib/sysfs.c (sysfs_get_resources): Removed warning about unsupported
800 64-bit addresses, they are now always supported.
802 * lspci.c (show_bases): Corrected printing of 64-bit addresses
805 * lib/configure: Enable 64-bit addresses on all Linux systems.
807 * lib/types.h: Don't pad 64-bit addresses to 16 xigits, only to 8 if they
810 2005-09-11 Martin Mares <mj@ucw.cz>
812 * Released as 2.1.99-test11.
814 * lspci.c: Removed unnecessary trailing zeros in pci_lookup_name() calls.
816 2005-09-10 Martin Mares <mj@ucw.cz>
818 * Released as 2.1.99-test10.
820 * pci.ids: Synchronized with the current database snapshot.
822 * update-pciids.sh: Changed the default URL for downloading pci.ids
823 to http://pciids.sourceforge.net/v2.2/pci.ids.
825 * lib/pci.h (PCI_LIB_VERSION): Added version identifier.
827 * lib/names.c: Rewritten the name database module almost from scratch.
828 Everything is much cleaner and there are hopefully no more memory leaks;
829 pci_lookup_name() now uses varargs in a backward compatible fashion.
830 Introduced PCI_LOOKUP_NO_NUMBERS.
832 The new code supports subsystem entries not tied to a specific device.
833 I had to extend the format of pci.ids in order to support it, so I have
834 extended the idea of the "C" (class) blocks and introduced "S" blocks
835 for subsystems. To avoid doing more incompatible changes in the future,
836 the parser skips unknown single-letter blocks without reporting errors.
838 2005-08-23 Martin Mares <mj@ucw.cz>
840 * Released as 2.1.99-test9.
842 * Makefile (OPT): Removed -fomit-frame-pointer, it's default in recent
843 gcc versions when optimizing anyway.
845 * Made the path to pci.ids customizable and independent on the SHAREDIR.
846 Just override IDSDIR in the top-level Makefile.
848 * pci.ids: Synchronized with the current database snapshot.
850 * lspci.man, setpci.man: Improved the man pages. Documented all access
851 methods and which operations are privileged.
853 * lspci.c: Another rewrite of config register caching, now also including
854 lots of internal checks. It should be now perfectly able to cope with
855 portions of the configuration space being inaccessible, for example
856 due to insufficient access rights.
858 * lspci.c (show_pcix_nobridge, show_pcix_bridge): Cleaned up dumping of PCI-X
859 capabilities. Includes partial support for PCI-X 2.0 (probably incomplete
860 as I haven't seen the spec).
862 * lspci.c: Quell warnings about unused parameters.
864 * lspci.c: Removed C++ comments.
866 * lib/header.h: Merged definitions of extended capabilities and some new
867 PCI-X capability bits from linux-2.6.11/include/pci.h.
869 * lspci.c (show_caps): Try to scan extended capabilities only if the
870 device has either PCI-X or PCI Express capability in its normal capability
873 * lib/dump.c (dump_init): Reading of dumps works again. The dump reader
874 now also remembers how much data it has read and refuses attempts to
875 access more than that.
877 * setpci.man, lspci.c, README: prefer spelling "buses" over "busses".
879 * lspci.c: If alloca() is not available, use xmalloc(), not malloc().
881 * lib/configure: Added x86_64 on Linux.
883 2005-08-22 Martin Mares <mj@ucw.cz>
885 * lib/filter.c (pci_filter_parse_slot): Fixed parsing of domain filters.
886 Thanks to Matthew Wilcox for bug report.
888 * lspci.c: Corrected spelling of "Hz" (it was "hz" at several places).
889 Thanks to Krzysztof Oledzki for pointing that out.
891 2004-08-19 Martin Mares <mj@ucw.cz>
893 * pciutils.spec (%attr): Setting attributes for /sbin/* is an anachronism,
894 because pciutils by default install to /usr/sbin. Update.
896 2004-08-13 Martin Mares <mj@ucw.cz>
898 * Released as 2.1.99-test8.
900 * lib/types.h, lib/pci.h, lib/sysdep.h: `byte' and `word' are
901 no longer exported to the outside world.
903 * README.Windows: Updated.
905 * maint/release: Substitute version number in win32/config.h.
907 * win32/config.h: Added.
909 * lib/sysdep.h (bzero, strcasecmp): are macros on Windows.
911 * compat/getopt.[ch]: Added copies of getopt.[ch] from the GNU
912 C library for use on systems where the default libraries lack
913 proper getopt. Currently used by the Windows port.
915 * lib/sysdep.h, lib/types.h: Updates of the Windows port from
918 * lib/types.h: If PCI_HAVE_Uxx_TYPES is defined, libpci doesn't define
919 its own u8, u16, u32, byte and word types and uses what the user
920 has supplied instead. With this change, all namespace clashes should
923 * Makefile, lib/Makefile: Updated dependencies.
925 * pciutils.h: Include lib/sysdep.h and move NONRET et al. there.
927 * lib/sysdep.h: No need to include <sys/types.h> on FreeBSD, because
928 it is included unconditionally in lib/types.h.
930 * Moved system-dependent stuff from lib/internal.h to lib/sysdep.h,
931 which is also used by the utilities. Also moved type declarations
932 from lib/pci.h to lib/types.h.
934 * All files: Prepend a "PCI_" prefix in front of all configuration
935 defines to avoid namespace clashes. CAVEAT: If there is any libpci
936 application using the (undocumented) defines, it has to be updated.
938 * lib/Makefile: Killed HAVE_OWN_HEADER_H, since we stopped sharing
939 headers with the kernel a couple of years ago.
941 * lib/sysfs.c (sysfs_get_resources): We have 7 resources, not 6.
943 * lspci.c (show_rom): Use the same logic for printing disabled
944 or unassigned ROM's as we do in show_bases() for the other BAR's.
946 * lib/generic.c (pci_generic_fill_info): Better reaction to
947 invalid 64-bit addresses. Also d->hdrtype should not include
948 bit 7, which caused mysterious errors on multi-function devices.
950 * lib/generic.c (pci_generic_fill_info): Fill in base addresses
951 even if the regions are known to be disabled. It is the client's
952 job to interpret them. (And it is not a trivial job if you want
953 to do it correctly, since you need to check I/O and memory enables
954 on all upstream bridges, too.) However, it could be interesting to
955 introduce functions for interpreting the addresses and even for
956 mapping the regions and doing I/O on them.
958 2004-07-30 Martin Mares <mj@ucw.cz>
960 * lspci.c: HyperTransport improvements from Maciej.
962 2004-07-11 Martin Mares <mj@ucw.cz>
964 * lib/sysfs.c (sysfs_get_resources): Arguments now correspond
965 to the format string. [Patch by Bill Nottingham]
967 2004-07-05 Martin Mares <mj@ucw.cz>
969 * Released as 2.1.99-test7.
971 * lspci.c (config_fetch): Wanted to merge Matthew's bug fix, but
972 ended up with rewriting the fetching mechanism to be fully dynamic,
973 but avoid reading config space registers not explicitly requested.
975 2004-06-29 Matthew Wilcox <willy@debian.org>
977 * lspci.c: More work on PCI Express dumping.
979 * lib/header.h: Updated PCI Express capability definitions.
981 * lib/proc.c (proc_read): Removed bogus warning.
983 * common.c (xrealloc): Introduced.
985 * lspci.man: Added -xxxx.
987 2004-06-27 Martin Mares <mj@ucw.cz>
989 * Released as 2.1.99-test6.
991 * lspci.c (show_msix), lib/header.h: Added dumping of MSI-X cap.
992 Patch by Roland Dreier <roland@topspin.com>, cleaned up by me.
994 * lspci.c (show_pcix_nobridge, show_pcix_bridge): Handle config_fetch()
997 * lib/header.h: Added PCI Express extended capabilities. Again by Matthew.
999 * lspci.c (show_express): Added dumping of PCI Express cap.
1000 Patch by Matthew Wilcox.
1002 * lib/header.h: Added a list of PCI 3.0 capabilities and also details
1003 on PCI Express caps. Patch by Matthew Wilcox <willy@debian.org>.
1005 * lspci.c (check_root): Gone. No explicit checks for root are needed,
1006 report correct errors reported by the libpci instead.
1008 * lspci.c: Added dumping of the extended config space on "-xxxx".
1009 Better caching of config registers.
1011 * setpci.c (main): Allow access to whole 4096 bytes of the config space.
1013 * lib/sysfs.c, lib/proc.c: Don't print error messages on short reads,
1014 just return the appropriate error code.
1016 * lib: Added support for extended (4096-byte) configuration space,
1017 currently implemented only in Linux proc and sysfs access methods
1018 and of course in the dump reader.
1020 2004-05-29 Martin Mares <mj@ucw.cz>
1022 * Released as 2.1.99-test5.
1024 * lib/pci.h: Windows don't have the standard u_int* types.
1026 * lib/internal.h: <sys/param.h> required on Windows for endianity
1029 * lib/i386-ports.c: Connected i386-io-windows.h.
1031 * lspci.c (check_root): geteuid() is not available on Windows.
1033 * lib/i386-io-windows.h: Added Windows port contributed by Alexander
1034 Stock <stock.alexander@gmx.de>.
1036 * lib/configure: Hopefully fixed SunOS port broken by various
1037 changes to the configure script.
1039 * Makefile, lib/configure: Cross-compilation support, patch by Maciej.
1041 2004-05-28 Martin Mares <mj@ucw.cz>
1043 * Released as 2.1.99-test4.
1045 * lspci.c (show_verbose): Header type 1 is probably legal for all
1046 types of bridges, not only for PCI-to-PCI bridges.
1048 * lspci.c (format_agp_rate): Write "x16", not "x@".
1049 (show_agp): rate[] could overflow.
1050 Bugs reported by Jakub Bogusz <qboosh@pld-linux.org>.
1052 * lspci.c (show_ht_*): Show HyperTransport capability with all its
1053 details. Once again code by Maciej simplified (i.e., possibly broken)
1056 * lib/header.h: Added declarations of HyperTransport capability.
1057 Again thanks to Maciej.
1059 * lspci.c: Decode all bits of the secondary status word in type 1 headers.
1060 Thanks to Maciej W. Rozycki <macro@ds2.pg.gda.pl> for the patch.
1062 2003-12-27 Martin Mares <mj@ucw.cz>
1064 * Released as 2.1.99-test3.
1066 * lspci.man, setpci.man: Document domains and correct spelling.
1068 * lib/dump.c (dump_init): Added ability to read domain numbers.
1070 * lspci.c: Devices in domains different from 0 have their slot number
1071 printed as "<domain>:<bus>:<slot>.<func>". Tree view supports domains
1074 * lib/filter.c: Slot filters understand domains.
1076 * lib/generic.c: Mention the domain in slot numbers in all error messages.
1078 * lib/internal.h: The #ifdef for Linux <asm/byteorder.h> was wrong.
1080 * lib/access.c (pci_get_dev): Added support for domains.
1082 * lib/sysfs.c (sysfs_scan): Read vendor and device ID from the config
1083 registers (or to be precise, leave it for the generic parts of the pcilib
1084 to do so) instead of reading them from the sysfs. It's faster this way.
1086 * lspci.c (show_pcix): Don't touch pci_dev->hdrtype, it's an internal
1087 variable. Better read it from the config registers (it's cached anyway).
1089 * lib/sysfs.c (sysfs_scan), lib/proc.c (proc_scan): Don't read the hdrtype.
1090 lib/generic.c (pci_generic_fill_info): If hdrtype is -1 (unset), read it.
1091 Saves lots of unnecessary file accesses.
1093 * lib/pci.h (PCIADDR_PORT_FMT): Use %llx instead of %Lx, because the latter
1094 is not supported by all C libraries.
1096 * Makefile: Always enter the lib directory (remember that we don't have
1097 full dependecies for the library in the top-level Makefile; hmmm, another
1098 thing to rewrite some day).
1100 * lib/sysfs.c: Added Linux sysfs access method based on the patch
1101 written by Matthew Wilcox <willy@fc.hp.com>.
1103 * lib/proc.c: Renamed the access method name from "/proc/bus/pci" to "Linux-proc".
1105 * lib/pread.h: The hacks to support pread on various versions
1106 of Linux libc moved there.
1108 * lib/proc.c (proc_setup): The return value of snprintf() varies
1109 between glibc versions, so we need to check both for a negative
1110 values and for too large values.
1112 * Removed last few references to the "Linux PCI Utilities", the
1113 package is pretty cross-platform now :)
1115 2003-12-27 Martin Mares <mj@ucw.cz>
1117 * Released as 2.1.99-test2.
1119 * README, pciutils.lsm, pciutils.spec: Use @VERSION@ to make the
1120 release scripts insert the current version. "make release" is gone.
1122 * maint/release, maint/release.pm: Added a new system of scripts for
1123 making releases including inter-version diffs etc.
1125 * Makefile: Cleaned up.
1127 * lib/fbsd-device.c: I patched another copy of this file by mistake,
1128 this time the version checks should be right.
1130 2003-12-27 Martin Mares <mj@ucw.cz>
1132 * Released as 2.1.99-test1.
1134 * pciutils.h, common.c, lspci.man, setpci.man, lib/internal.h:
1135 Remove shadows of the syscall access method which was never
1138 * update-pciids.sh: Try to preserve permissions of the old file
1139 if chmod supports --reference. Should close Debian Bug #223740.
1141 * lib/proc.c (proc_setup): Increased path name length limit to 1024.
1142 Thanks for Redhat and Mandrake for inspiration.
1144 * lib/configure: Recognize ppc and ppc64, both have 64-bit addresses.
1145 Grabbed from Redhat (Fedora) patches.
1147 2003-12-27 Martin Mares <mj@ucw.cz>
1149 Merged bug fixes from Debian patches:
1151 * lspci.c (show_verbose): "Cache Line Size" should be capitalized.
1153 * lspci.c (show_pcix_nobridge): Added a missing newline.
1155 * lib/proc.c (proc_scan): When reading the header type, don't
1156 forget to clear the topmost bit indicating that the device has
1159 2003-12-27 Martin Mares <mj@ucw.cz>
1161 Updated the FreeBSD port. Thanks to Samy Al Bahra <samy@kerneled.com>
1164 * lib/Makefile: Add ${FREEBSD_SYS} to the include path if it's defined.
1165 * lib/fbsd-device.c: Select the right set of system includes according
1166 to __FreeBSD_version.
1168 2003-12-27 Martin Mares <mj@ucw.cz>
1170 Merged support for Solaris on i386 by Bill Moore <billm@eng.sun.com>
1173 * lib/configure: Recognize SunOS.
1174 * lib/internal.h: Learn how to recognize byte order on SunOS.
1175 * lib/i386-ports.c: Split OS-dependent I/O port access from i386-ports.c.
1176 * lib/i386-io-linux.h: Linux specific part.
1177 * lib/i386-io-hurd.h: GNU/Hurd specific part.
1178 * lib/i386-io-sunos.h: SunOS specific part.
1180 2003-12-26 Martin Mares <mj@ucw.cz>
1182 * lib/header.h (PCI_*_MASK): Cast to pciaddr_t explicitly.
1184 * lib/pci.h: Types declared in <sys/types.h> should be usable on all
1185 platforms we currently support, so kill the forest of #ifdef's and
1186 use them in all cases.
1188 * lib/pci.h: Use ULONG_MASK to decide whether we should use long
1189 or long long to represent a 64-bit address. Killed HAVE_LONG_ADDRESS.
1190 Define format strings for addresses, port numbers and IRQ numbers
1193 * lib/proc.c (proc_scan): Use PCIADDR_T_FMT for scanf'ing addresses.
1195 2003-12-26 Marco Gerards <metgerards@student.han.nl>
1197 Added support for the GNU Hurd (cleaned up by Martin Mares):
1199 * lib/configure [GNU]: Use the i386 ports for configuration access.
1200 * lib/i386-ports.c: Don't call iopl() on the Hurd.
1201 * lib/pci.h [OS_GNU]: Include <sys/types.h> and use it for defining
1204 2003-12-26 Martin Mares <mj@ucw.cz>
1206 * lspci.c (show_pcix_bridge, show_pcix_nobridge): Don't forget to call
1207 config_fetch() to ensure that the registers have been read. Thanks to
1208 Bill Wood <bill.wood@hp.com> for the patch.
1210 * lspci.c: Ensure that failure of config_fetch() is handled correctly
1213 * lspci.man: There was one more explicit reference to /usr/share/pci.ids.
1214 Changed to @SHAREDIR@. Patch from Maciej W. Rozycki <macro@ds2.pg.gda.pl>.
1216 * setpci.c (main): Better error messages.
1218 * setpci.c (ex_op): The demo mode should disable only writing, not reading.
1220 * setpci.man: The documentation was inconsistent on what should -D do.
1221 Document the new behaviour.
1223 * pciutils.h, common.c, setpci.c: Introduced a NONRET macro encapsulating
1224 the GCC specific __attribute__((noreturn)) and killed the hack with
1225 redefining __attribute__ on non-GCC compilers.
1227 * Makefile: Added missing dependencies. Parallel builds work now.
1228 Problem reported by Andreas Haumer <andreas@xss.co.at>, but I chose
1231 * Makefile (MANDIR): Use `:=' instead of `=' to avoid executing the shell
1232 command every time $(MANDIR) is referenced.
1234 * lspci.c (main): The error message for `lspci -s' incorrectly mentioned
1235 a `-f' switch. Reported by Steve Finney <Steve.Finney@SpirentCom.COM>.
1237 * lib/generic.c: Removed memory leak in pci_generic_bus_scan().
1238 Reported by Gary Parnes <gary_parnes@terago.com>.
1240 * Replaced obsolete syntax of __attribute__((unused)) in the middle of
1241 parameter declarations (which is no longer supported by GCC 3.1) by the
1242 current syntax (attribute at the end). Thanks to pixel@mandrakesoft.com
1243 for reporting this problem.
1245 * Removed CVS $Id$ tags from all files.
1247 * Makefile: Added some more warnings.
1249 * setpci.c: Cleaned up mask/value code.
1251 2003-12-08 Thayne Harbaugh <tharbaugh@lnxi.com>
1253 * setpci.c: Individual bits to be set can be specified as <value>:<mask>.
1255 2003-11-29 Martin Mares <mj@ucw.cz>
1257 * Imported the pciutils sources to my Arch repository. Good-bye, CVS.
1259 2003-01-04 Martin Mares <mj@ucw.cz>
1261 * Released as 2.1.11.
1263 * Makefile: Changed configuration of installation directories --
1264 all paths are now set at the top of the Makefile instead of being
1265 scattered between the installation rules. The default installation
1266 now goes always to /usr/local regardless of the OS as most distributions
1267 already contain some version of pciutils and we don't want custom
1268 installations to interfere with the default ones.
1270 * Makefile: Removed a couple of ancient install hacks: we no longer
1271 try to avoid overwriting a newer pci.ids file (users are now expected
1272 to use update-ids) and we don't try to remove /etc/pci.ids (a long time
1273 has passed since the last version which used it).
1275 * Makefile: Paths to pci.ids in man pages automatically get the right path.
1277 * Added the update-ids utility.
1279 * lib: Removed partially implemented "syscall" access method which will
1280 probably never be needed.
1282 2002-12-27 Martin Mares <mj@ucw.cz>
1284 * lib/nbsd-libpci.c: Cleaned up and hopefully made it endian safe.
1286 * lib/generic.c (pci_generic_scan_bus): Added work-around for devices with
1287 discontiguous numbering of functions. This is already present in the Linux
1288 kernel for several years, but I forgot to update pciutils as well.
1290 2002-12-26 Martin Mares <mj@ucw.cz>
1292 * lib/header.h, lspci.c: Dump AGP3 flags and speeds.
1294 * lib/pci.h, Makefile: Removed HAVE_OWN_HEADER_H. Always use our own header,
1295 there is no reason to prefer the kernel version.
1297 * lib/proc.c (proc_scan): Don't forget to initialize hdrtype.
1299 * Added preliminary version of NetBSD support by Quentin Garnier
1300 <netbsd@quatriemek.com>.
1302 2002-04-06 Martin Mares <mj@ucw.cz>
1304 * lspci.c: Mention "-xxx" in the help.
1306 2002-03-30 Martin Mares <mj@ucw.cz>
1308 * Released as 2.1.10.
1310 * Removed pci.ids from the CVS as they are now maintained separately.
1311 They are still included in the tarball, but if you are building pciutils
1312 from CVS sources or you want to get a newer ID file than the one distributed,
1313 just use "make update-ids" to download the most recent snapshot from
1316 * Makefile, README: Updated accordingly.
1318 * Makefile: Added a couple of maintenance targets.
1320 * maint/*: Maintainer's utilities now reside here (present only in CVS,
1321 not in the tarball).
1323 * lib/names.c (parse_name_list): End-of-line comments are no longer
1324 supported. Hashes are now perfectly valid in all names and they start
1325 a comment only at the start of the line.
1327 2002-03-26 Martin Mares <mj@ucw.cz>
1329 * README: Rewritten.
1331 * Makefile: When the currently installed pci.ids file is newer than
1332 the version to be installed, don't overwrite it. Suggested by
1333 Jean Delvare <khali@linux-fr.org>.
1335 2002-03-24 Martin Mares <mj@ucw.cz>
1337 * lspci.c (show_pcix_bridge): Added PCI-X capability display.

1404 * pciutils.spec: Added German description.
1406 * lib/names.c (pci_lookup_name): Added a cheat for case that subsystem ID's
1407 are the same as device ID and just output subsystem name according to
1410 * lib/proc.c: Use UNUSED instead of __attribute__((unused)).
1412 * lib/pci.h: Added the correct typedefs for AIX.
1414 * lib/generic.c (pci_generic_scan_bus): Export.

1434 2000-04-17 Martin Mares <mj@albireo.ucw.cz>
1436 * Released as 2.1.6.
1438 * pci.ids: Added a large batch of ID's contributed by Gunther
1439 Mayer <gunther.mayer@braunschweig.netsurf.de> and synced the
1440 list with the 2.3.99pre6 kernel.
1442 Thu Mar 9 13:11:39 2000 Martin Mares <mj@albireo.ucw.cz>
1444 * lib/example.c: Added a simple example of how to use

1469 Mon Jan 24 11:24:43 2000 Martin Mares <mj@albireo.ucw.cz>
1471 * Makefile: Modified to work with the Linux FHS brain-damaged idea
1472 of putting man pages to /usr/share/man. Now we choose either /usr/man
1473 or /usr/share/man depending on which one exists.
1475 Sun Jan 23 10:52:34 2000 Martin Mares <mj@albireo.ucw.cz>
1477 * pci.ids: Synced with Linux 2.3.40.
1479 * Released as version 2.1.4.
1481 Thu Jan 20 11:08:32 2000 Martin Mares <mj@albireo.ucw.cz>

1487 * lspci.c (format_agp_rate): Better formatting of AGP rates.
1489 * pci.ids: New ID's.
1491 * lib/configure: Added configuration for ia64 (the same as for Alpha).
1492 Patch from Stephane Eranian <eranian@cello.hpl.hp.com>.

1498 * pci.ids: New ID's.
1500 * lspci.c: Alpha IO_FORMAT fix by Andrea Arcangeli.
1502 * lib/access.c: Corrected order of access methods -- it's wonderful how
1503 long could such a bug remain unspotted. Thanks go to Andreas Schockenhoff.
1505 Sat Dec 11 23:34:48 1999 Martin Mares <mj@albireo.ucw.cz>
1507 * Released as version 2.1.2.
1509 * lib/names.c (pci_lookup_name): Fixed printing of unknown subsystem ID's.
1511 Sat Dec 4 13:11:03 1999 Martin Mares <mj@albireo.ucw.cz>
1513 * Released as version 2.1.1.
1515 * pci.ids: Several new ID's.
1517 * setpci.c (exec_op): Don't forget to increment address after writing
1518 single value, so that `30.b=12,34,56,78' works as expected. Reported
1519 by Petr Soucek <petr@ryston.cz>.
1521 Wed Nov 3 10:24:38 1999 Martin Mares <mj@albireo.ucw.cz>
1523 * lspci.c (show_terse): If prog-if is zero, but it's present in the
1526 Sat Oct 30 11:06:35 1999 Martin Mares <mj@albireo.ucw.cz>
1528 * Released as version 2.1.
1530 * pci.ids: Synced to devlist.h in 2.3.24 kernel. Merged in
1531 lots of contributed entries.
1533 Thu Oct 14 10:40:12 1999 Dave Jones <dave@powertweak.com>
1535 * pci.ids: Added lots of subsystem definitions.
1537 Sat Oct 9 14:32:28 1999 Martin Mares <mj@albireo.ucw.cz>
1539 * setpci.man: Better example.
1541 * lspci.c: Resolve prog-if names.
1543 * lib/names.c: Adapted to new pci.ids syntax.
1545 * pci.ids: Reorganized the pci.ids file. Subsystems are listed
1546 under devices, classes can optionally contain prog-if information.
1547 New ID's, as usually.
1549 Wed Sep 22 09:45:24 1999 Martin Mares <mj@albireo.ucw.cz>
1551 * pci.ids: New ID's. As usually.
1553 * lspci.c (show_htype1, show_htype2): Don't show `closed' bridge windows
1554 unless we're vvvery verbose.
1556 Mon Sep 20 11:22:54 1999 Martin Mares <mj@albireo.ucw.cz>
1558 * lspci.c (show_htype2): Don't forget a TAB before the "I/O window" line.
1560 Tue Sep 14 09:31:01 1999 Martin Mares <mj@albireo.ucw.cz>
1562 * pci.ids: New ID's. Again.
1564 Thu Aug 5 17:45:42 1999 Martin Mares <mj@albireo.ucw.cz>
1566 * lspci.c (show_size): Don't show size if it's zero (usually
1567 due to bus-centric mode being enabled).
1569 Tue Jul 20 13:25:09 1999 Martin Mares <mj@albireo.ucw.cz>
1571 * lib/pci.h: Types are OS dependent.
1573 * lib/internal.h: Byte order hacks are OS dependent.
1575 * lib/configure: Recognize FreeBSD. Also set OS_XXX according to the OS.
1577 * lib/Makefile, lib/access.c: Added fbsd-device target.
1579 * pci.ids: Added an entry for PLX 9080 bridges with subsystem ID
1580 incorrectly set to device ID.
1582 * README: Added a note that we support FreeBSD.
1584 * Makefile (PREFIX, ROOT): Set it depending on the OS.
1585 (%.8): Grrr, BSD date is not able to convert date formats the same way
1586 as GNU date does. Use sed instead.
1587 (install): Use `-c' when calling install.
1589 * lib/fbsd-device.c: Added FreeBSD /dev/pci access module contributed
1590 by Jari Kirma <kirma@cs.hut.fi>.
1592 * lib/proc.c: Rewrote the pread/pwrite things once again. Use pread
1593 and pwrite only when we are certain it's safe (i.e., glibc 2.1
1594 on all architectures or any libc on a i386 where we really know
1595 how to use syscalls directly). In all other cases, emulate it
1596 with lseek/read/write.
1598 * pci.ids: Some more IDs.
1600 Mon Jul 19 14:10:36 1999 Martin Mares <mj@albireo.ucw.cz>
1602 * pci.ids: Added IDs of parallel port controller cards as sent
1603 by Tim Waugh <tim@cyberelk.demon.co.uk>.
1605 Wed Jul 7 00:55:48 1999 Martin Mares <mj@albireo.ucw.cz>
1607 * lib/proc.c (proc_scan): HAVE_LONG_ADDRESS instead of HAVE_64BIT_ADDRESS.
1609 * lspci.c: ADDR_FORMAT now depends on both HAVE_64BIT_ADDRESS and
1612 * lib/configure: HAVE_64BIT_ADDRESS now doesn't imply that the addresses
1613 are represented as long long. Introduced a new flag HAVE_LONG_ADDRESS
1614 to indicate this. Both Sparc architectures now use both 64BIT_ADDRESS
1615 and LONG_ADDRESS since they have 32-bit userland, but don't set LONG_ADDRESS
1618 * lspci.c (show_msi): Added dumping of the MSI capability.
1619 (show_slotid): The same for SlotID capability.
1620 (show_caps): Seperated capability dumping, because it should
1621 be used for both htype0 and htype1. Even PCI 2.2 doesn't mention
1622 layout of htype2, so I'm a bit unsure about it wrt capabilities
1623 -- they at least have to live somewhere else since address 0x34
1624 is already defined differently in htype2.
1626 * lib/header.h (PCI_STATUS_UDF): Marked as obsolete (PCI 2.2).
1627 (PCI_BASE_ADDRESS_MEM_TYPE_1M): Ditto.
1628 (PCI_CAP_ID_*): Added some new capabilities defined in PCI 2.2.
1630 * lspci.c (show_htype0): Mask out lowest 2 bits from all capability pointers
1631 (required by the PCI 2.2 specs).
1633 Mon Jul 5 12:45:19 1999 Martin Mares <mj@albireo.ucw.cz>
1635 * lspci.c (show_size): Added new function for dumping of region sizes.
1636 (show_rom): Added. Now correctly dumps unassigned ROM addresses, disabled
1639 * lib/pci.h (struct pci_dev): known_fields moved to the public part
1642 * Added support for region sizes. Needs support in the kernel, because
1643 sizes have to be scanned before drivers initialize yourself. pci_fill_info()
1644 now returns a bitmask of what fields were really read.
1646 Mon Jun 28 18:37:51 1999 Dave Jones <dave@powertweak.com>
1649 Added `uninstall' target - removes all traces of pciutils.
1651 - Lots of cleanups in the ATI, S3, Adaptec vendors.
1652 - Changed Compaq QVision 1280/p definitions, as it's not possible
1653 to determine the revision from the device ID.
1654 - Same for the Tseng ET4000.
1655 The id's said I had a rev C, when it was actually a rev B.
1656 - Removed some unnecessary strings
1657 `PCI'. Unless it's an AGP card, it should be obvious that it's PCI.
1658 `Ethernet card'. This should be determined from config space.
1659 - Lots of other new vendors & devices
1660 - Other additional small cleanups.
1662 Mon Jun 21 22:11:10 1999 Martin Mares <mj@albireo.ucw.cz>
1664 * lib/names.c (pci_lookup_name): When device ID lookup
1665 fails, return hexadecimal device ID instead of vendor ID.
1666 Well spotted by Axel Bodemann <Axel.Bodemann@ruhr-uni-bochum.de>,
1667 I've just extended the fix to subsystem ID's.
1669 Thu Jun 17 19:48:21 1999 Martin Mares <mj@albireo.ucw.cz>
1671 * lspci.c (show_agp): Bug fix from Petr Vandrovec
1672 <vandrove@vc.cvut.cz>. The command register was displayed
1675 Wed Jun 2 22:42:44 1999 Martin Mares <mj@albireo.ucw.cz>
1677 * lib/proc.c (SYS_pread, SYS_pwrite): Use hard-coded
1678 numbers if not supplied by the libc.
1680 Wed May 19 13:24:39 1999 Martin Mares <mj@albireo.ucw.cz>
1682 * Released the whole package as version 2.0.
1684 Fri May 14 22:42:02 1999 Martin Mares <mj@albireo.ucw.cz>
1686 * pci.ids: Added several new ID's contributed by people
1687 on the linux-pci list.
1689 Mon Apr 19 15:21:08 1999 Jakub Jelinek <jj@ultra.linux.cz>
1691 * lspci.c: Display I/O addresses correctly on sparc64.
1692 * lib/header.h: Ditto.
1694 * lib/configure: On sparc set HAVE_64BIT* as well, we want
1695 a binary which works on both 32bit and 64bit SPARCs.
1697 Sun Apr 18 21:14:58 1999 Martin Mares <mj@albireo.ucw.cz>
1699 * lspci.c, lib/proc.c: Alpha compilation fixes from Matthew Jacob
1702 * pci.ids: A lot of updates from Adam J. Richter <adam@yggdrasil.com>.
1704 Sun Feb 28 22:26:21 1999 Martin Mares <mj@albireo.ucw.cz>
1706 * lspci.c (do_map_bus): Don't dump functions 1--7 if not flagged
1707 as a multi-function device, because several single-function devices
1708 don't decode the function bits at all.
1710 Sun Feb 14 23:48:22 1999 Martin Mares <mj@albireo.ucw.cz>
1712 * Makefile (install): Don't use "-o root -g root" for installation
1713 since it breaks on machines where programs are not installed by root.
1714 Reported by Richard Gooch <rgooch@atnf.csiro.au>
1716 Tue Feb 9 15:54:39 1999 Martin Mares <mj@albireo.ucw.cz>
1718 * lspci.c (show_bases): Use new address masking macros and pciaddr_t.
1720 * lib/pci.h: Using pciaddr_t for bus addresses, which are 32-bit
1721 or 64-bit depending on CPU.
1723 * lib/pci.h (PCI_ADDR_MEM_MASK): Added macros for address masks
1724 according to bus address width.
1726 Thu Jan 28 20:54:16 1999 Martin Mares <mj@albireo.ucw.cz>
1728 * Released as 1.99.4.
1730 * lspci.c: Capability list parser now recognizes both AGP
1731 registers and PCI Power Management registers (the latter
1732 is mainly guesswork based on DEC/Intel 21153 bridge specs
1733 since I don't have the PCI Power Management document).
1735 * lspci.c: Replaced numerous occurences of (x & flag) ? '+' : '-'
1738 * lspci.c: Added bridge checks to bus mapping code.
1740 Wed Jan 27 14:59:16 1999 Martin Mares <mj@albireo.ucw.cz>
1742 * lspci.c: Implemented bus mapping mode (-M).
1744 * lspci.c (scan_devices): Split to scan_devices() and scan_device().
1745 (show): Split to show() and show_device().
1747 * lib/access.c (pci_init): When a->method == PCI_ACCESS_AUTO,
1748 set it to the real access method afterwards.
1750 Mon Jan 25 23:46:13 1999 Martin Mares <mj@albireo.ucw.cz>
1752 * lib/generic.c (pci_generic_fill_info): If in buscentric mode,
1753 don't check PCI_COMMAND for I/O and memory enables.
1755 Mon Jan 25 21:28:49 1999 Martin Mares <mj@albireo.ucw.cz>
1757 * Makefile: Added target `release' which substitutes new version
1758 number to .spec, .lsm and README. Also rewrote target `dist'.
1760 * Released as 1.99.3.
1762 Sun Jan 24 22:10:36 1999 Martin Mares <mj@albireo.ucw.cz>
1764 * lib/header.h: Until kernel adopts new layout of PCI
1765 includes (i.e., separate declaration of header structure,
1766 functions and device IDs), which is not going to happen
1767 before 2.3, we'll use our own definiton of the header.
1769 * lspci.c (show_verbose): Display `Cap' flag in device status.
1771 * lspci.c (show_htype0): Display capability lists whereever
1772 available. The only capability name we recognize now is `AGP'.
1773 Unfortunately, capabilities are stored in device-dependent
1774 portion of the configuration space and are thus available
1775 only to root unless you read a dump.
1777 * lspci.c (scan_devices): Use cache instead of buffering.
1779 * lib/buffer.c: Removed (obsoleted by the cache).
1781 * lib/access.c: Added general caching mechanism.
1783 Sat Jan 23 21:30:54 1999 Martin Mares <mj@albireo.ucw.cz>
1785 * pci.ids: Added few devices.
1787 Fri Jan 22 19:29:31 1999 Martin Mares <mj@albireo.ucw.cz>
1789 * Version string is now defined in top-level Makefile, exported
1790 to the configure script and also substituted to man pages.
1792 * lspci.c (show_bases): Rewrote displaying of 64-bit addresses.
1793 (show_verbose): Rewrote interrupt display logic.
1795 * lib/i386-ports.c: Include sys/io.h only on glibc systems.
1797 * lib/configure: Rewrote detection of Linux versions. Now it
1798 works on 2.0 kernels (only with direct/dump access, of course).
1800 * lib/internal.h: New bytesex macros using <asm/byteorder.h>
1803 * lib/proc.c (proc_read, proc_write): Distinguish between short
1804 read/write and real errors.
1806 * lspci.c (show_htype{0,1}): Always use d->dev->rom_base_addr since
1807 libpci respects buscentric mode automatically.
1809 * lspci.c (show_hex_dump): For CardBus bridges, print out 128
1810 bytes of header (the whole standard part).
1812 * common.c: pcilib options are now all uppercase. Also moved
1813 PCI access debugging option here.
1815 * Released as 1.99.2.
1817 Wed Jan 20 22:50:35 1999 Martin Mares <mj@albireo.ucw.cz>
1819 * Wrote configure script and rewrote Makefiles.
1821 * Removed few unused variables.
1823 Wed Jan 20 12:21:56 1999 Martin Mares <mj@albireo.ucw.cz>
1825 * common.c: Moved several functions used in both setpci and lspci
1826 here. This includes parsing of libpci-related options.
1828 * More library tweaks.
1830 * filter.c, names.c: Moved to library.
1832 * setpci: Rewritten to use the library.
1834 * Released as 1.99.1.
1836 Tue Jan 19 23:00:12 1999 Martin Mares <mj@albireo.ucw.cz>
1838 * lspci.c (scan_devices): For cardbus bridges, read first 128
1839 bytes of config space to get full standard header.
1841 * Makefile (CFLAGS): Removed "-Wno-unused".
1843 * Started the "New Generation" branch and introduced the
1846 * lspci: Rewritten to use the library.
1848 Tue Jan 19 22:24:08 1999 Martin Mares <mj@albireo.ucw.cz>
1850 * Released as version 1.10.
1852 Mon Jan 18 08:51:17 1999 Martin Mares <mj@albireo.ucw.cz>
1854 * lspci.8, setpci.8: Miscellaneous fixes as suggested by
1855 Dag Wieers <dag@digibel.be>.
1857 Sun Nov 29 20:05:56 1998 Martin Mares <mj@albireo.ucw.cz>
1859 * pciutils.spec (Name): Update from Krzysztof G. Baranowski.
1861 Sun Nov 22 10:49:56 1998 Martin Mares <mj@albireo.ucw.cz>
1863 * Makefile, pciutils.h: Moved pci.ids to /usr/share.
1865 * Released as version 1.09.
1867 Wed Nov 18 15:47:05 1998 Martin Mares <mj@albireo.ucw.cz>
1869 * lspci.c (show_htype1): Fixed displaying of prefetchable memory behind
1870 bridge. Thanks to Petr Vandrovec <vandrove@vc.cvut.cz> for bug report.
1872 Fri Oct 23 18:59:19 1998 Martin Mares <mj@albireo.ucw.cz>
1874 * setpci.c: Don't include <syscall-list.h> with glibc >= 2.1.
1876 Mon Oct 19 21:53:30 1998 Martin Mares <mj@albireo.ucw.cz>

2007 * Makefile, pciutils.h: Include local pci.h instead of <linux/pci.h>
2008 if available. This should avoid all problems with official kernel
2009 not synchronized to newer PCI code in CVS -- standard distribution
2010 of pciutils now contains pci.h from current CVS kernel, pciutils
2011 in CVS contain no pci.h and use the correct kernel include.
2013 * Makefile: Fixed installation path for man pages.
2015 Sat Feb 7 15:15:46 1998 Martin Mares <mj@albireo.ucw.cz>

2023 Tue Feb 3 20:56:00 1998 Martin Mares <mj@albireo.ucw.cz>
2025 * Makefile: Recognize architecture by calling uname and pass it as ARCH_xxx
2026 to all the C sources. This should eliminate problems with 32-bit compilers
2029 * lspci.c (show_verbose): Recognize CardBus bridge header type.
2030 (show_htype2): Stub routine.
2031 (scan_config): Write sensible error message if the kernel denies reading of
2032 upper part of the PCI config space.
