1 2006-05-10 Martin Mares <mj@ucw.cz>
3 * lib/configure, lib/fbsd-device.c: Added support for GNU/kFreeBSD.
4 Thanks to Petr Salinger for the patch.
6 2006-05-05 Martin Mares <mj@ucw.cz>
10 * lspci.c (scan_device): The -D switch didn't work as intended
13 2006-05-05 Martin Mares <mj@ucw.cz>
17 * pci.ids: Updated to the current database snapshot.
19 * lib/obsd-device.c (and other files in lib/*): Added OpenBSD
20 interface by Matthieu Herrb <matthieu.herrb@laas.fr>, based on
21 the existing FreeBSD interface.
23 * Moved pciutils to a GIT repository, which now contains merged
24 history from both CVS and Arch. Good bye, TLA!
26 2006-03-21 Martin Mares <mj@ucw.cz>
28 * lspci.c (show_slot_name): Avoid the previous changes in default
29 display of domain name when in machine-readable mode. However, `-D'
30 forces domain display even there.
32 * lspci.man: Added a warning on -m being the only format, which is
33 guaranteed to be stable between lspci versions.
35 2006-03-13 Martin Mares <mj@ucw.cz>
37 * lspci.man: Documented the -D switch.
39 * lspci.c (show_slot_name, scan_device): If there are multiple PCI
40 domains or if the `-D' switch is used, show the domain number for
43 * lspci.c (show_verbose): Report cache line size in bytes.
45 * update-pciids.sh: Use curl if available. Patch by Matthew Wilcox.
47 2006-01-04 Martin Mares <mj@ucw.cz>
49 * lspci.c (show_express_link): Fixed decoding of link status register.
50 Thanks to Roland Dreier for his report.
52 2005-12-12 Martin Mares <mj@ucw.cz>
54 * lib/nbsd-libpci.c: If libpci is used by an ordinary user, allow
55 at least read-only access. Patch by Pavel Celeda <celeda@liberouter.org>.
57 * Makefile: Corrected library path on NetBSD.
59 2005-11-26 Martin Mares <mj@ucw.cz>
63 * lspci.c (show_machine): Subsystem vendors were printed incorrectly
64 in machine-readable modes. Thanks to Pavel Celeda for a bug report.
66 2005-10-11 Martin Mares <mj@ucw.cz>
68 * lspci.c (new_bus): Fixed a memory leak. Thanks to Paul Sangree for reporting it.
70 2005-09-21 Martin Mares <mj@ucw.cz>
74 * pci.ids: Updated copyright header.
76 * lib/sysfs.c (sysfs_get_resources): Removed warning about unsupported
77 64-bit addresses, they are now always supported.
79 * lspci.c (show_bases): Corrected printing of 64-bit addresses
82 * lib/configure: Enable 64-bit addresses on all Linux systems.
84 * lib/types.h: Don't pad 64-bit addresses to 16 xigits, only to 8 if they
87 2005-09-11 Martin Mares <mj@ucw.cz>
89 * Released as 2.1.99-test11.
91 * lspci.c: Removed unnecessary trailing zeros in pci_lookup_name() calls.
93 2005-09-10 Martin Mares <mj@ucw.cz>
95 * Released as 2.1.99-test10.
97 * pci.ids: Synchronized with the current database snapshot.
99 * update-pciids.sh: Changed the default URL for downloading pci.ids
100 to http://pciids.sourceforge.net/v2.2/pci.ids.
102 * lib/pci.h (PCI_LIB_VERSION): Added version identifier.
104 * lib/names.c: Rewritten the name database module almost from scratch.
105 Everything is much cleaner and there are hopefully no more memory leaks;
106 pci_lookup_name() now uses varargs in a backward compatible fashion.
107 Introduced PCI_LOOKUP_NO_NUMBERS.
109 The new code supports subsystem entries not tied to a specific device.
110 I had to extend the format of pci.ids in order to support it, so I have
111 extended the idea of the "C" (class) blocks and introduced "S" blocks
112 for subsystems. To avoid doing more incompatible changes in the future,
113 the parser skips unknown single-letter blocks without reporting errors.
115 2005-08-23 Martin Mares <mj@ucw.cz>
117 * Released as 2.1.99-test9.
119 * Makefile (OPT): Removed -fomit-frame-pointer, it's default in recent
120 gcc versions when optimizing anyway.
122 * Made the path to pci.ids customizable and independent on the SHAREDIR.
123 Just override IDSDIR in the top-level Makefile.
125 * pci.ids: Synchronized with the current database snapshot.
127 * lspci.man, setpci.man: Improved the man pages. Documented all access
128 methods and which operations are privileged.
130 * lspci.c: Another rewrite of config register caching, now also including
131 lots of internal checks. It should be now perfectly able to cope with
132 portions of the configuration space being inaccessible, for example
133 due to insufficient access rights.
135 * lspci.c (show_pcix_nobridge, show_pcix_bridge): Cleaned up dumping of PCI-X
136 capabilities. Includes partial support for PCI-X 2.0 (probably incomplete
137 as I haven't seen the spec).
139 * lspci.c: Quell warnings about unused parameters.
141 * lspci.c: Removed C++ comments.
143 * lib/header.h: Merged definitions of extended capabilities and some new
144 PCI-X capability bits from linux-2.6.11/include/pci.h.
146 * lspci.c (show_caps): Try to scan extended capabilities only if the
147 device has either PCI-X or PCI Express capability in its normal capability
150 * lib/dump.c (dump_init): Reading of dumps works again. The dump reader
151 now also remembers how much data it has read and refuses attempts to
152 access more than that.
154 * setpci.man, lspci.c, README: prefer spelling "buses" over "busses".
156 * lspci.c: If alloca() is not available, use xmalloc(), not malloc().
158 * lib/configure: Added x86_64 on Linux.
160 2005-08-22 Martin Mares <mj@ucw.cz>
162 * lib/filter.c (pci_filter_parse_slot): Fixed parsing of domain filters.
163 Thanks to Matthew Wilcox for bug report.
165 * lspci.c: Corrected spelling of "Hz" (it was "hz" at several places).
166 Thanks to Krzysztof Oledzki for pointing that out.
168 2004-08-19 Martin Mares <mj@ucw.cz>
170 * pciutils.spec (%attr): Setting attributes for /sbin/* is an anachronism,
171 because pciutils by default install to /usr/sbin. Update.
173 2004-08-13 Martin Mares <mj@ucw.cz>
175 * Released as 2.1.99-test8.
177 * lib/types.h, lib/pci.h, lib/sysdep.h: `byte' and `word' are
178 no longer exported to the outside world.
180 * README.Windows: Updated.
182 * maint/release: Substitute version number in win32/config.h.
184 * win32/config.h: Added.
186 * lib/sysdep.h (bzero, strcasecmp): are macros on Windows.
188 * compat/getopt.[ch]: Added copies of getopt.[ch] from the GNU
189 C library for use on systems where the default libraries lack
190 proper getopt. Currently used by the Windows port.
192 * lib/sysdep.h, lib/types.h: Updates of the Windows port from
195 * lib/types.h: If PCI_HAVE_Uxx_TYPES is defined, libpci doesn't define
196 its own u8, u16, u32, byte and word types and uses what the user
197 has supplied instead. With this change, all namespace clashes should
200 * Makefile, lib/Makefile: Updated dependencies.
202 * pciutils.h: Include lib/sysdep.h and move NONRET et al. there.
204 * lib/sysdep.h: No need to include <sys/types.h> on FreeBSD, because
205 it is included unconditionally in lib/types.h.
207 * Moved system-dependent stuff from lib/internal.h to lib/sysdep.h,
208 which is also used by the utilities. Also moved type declarations
209 from lib/pci.h to lib/types.h.
211 * All files: Prepend a "PCI_" prefix in front of all configuration
212 defines to avoid namespace clashes. CAVEAT: If there is any libpci
213 application using the (undocumented) defines, it has to be updated.
215 * lib/Makefile: Killed HAVE_OWN_HEADER_H, since we stopped sharing
216 headers with the kernel a couple of years ago.
218 * lib/sysfs.c (sysfs_get_resources): We have 7 resources, not 6.
220 * lspci.c (show_rom): Use the same logic for printing disabled
221 or unassigned ROM's as we do in show_bases() for the other BAR's.
223 * lib/generic.c (pci_generic_fill_info): Better reaction to
224 invalid 64-bit addresses. Also d->hdrtype should not include
225 bit 7, which caused mysterious errors on multi-function devices.
227 * lib/generic.c (pci_generic_fill_info): Fill in base addresses
228 even if the regions are known to be disabled. It is the client's
229 job to interpret them. (And it is not a trivial job if you want
230 to do it correctly, since you need to check I/O and memory enables
231 on all upstream bridges, too.) However, it could be interesting to
232 introduce functions for interpreting the addresses and even for
233 mapping the regions and doing I/O on them.
235 2004-07-30 Martin Mares <mj@ucw.cz>
237 * lspci.c: HyperTransport improvements from Maciej.
239 2004-07-11 Martin Mares <mj@ucw.cz>
241 * lib/sysfs.c (sysfs_get_resources): Arguments now correspond
242 to the format string. [Patch by Bill Nottingham]
244 2004-07-05 Martin Mares <mj@ucw.cz>
246 * Released as 2.1.99-test7.
248 * lspci.c (config_fetch): Wanted to merge Matthew's bug fix, but
249 ended up with rewriting the fetching mechanism to be fully dynamic,
250 but avoid reading config space registers not explicitly requested.
252 2004-06-29 Matthew Wilcox <willy@debian.org>
254 * lspci.c: More work on PCI Express dumping.
256 * lib/header.h: Updated PCI Express capability definitions.
258 * lib/proc.c (proc_read): Removed bogus warning.
260 * common.c (xrealloc): Introduced.
262 * lspci.man: Added -xxxx.
264 2004-06-27 Martin Mares <mj@ucw.cz>
266 * Released as 2.1.99-test6.
268 * lspci.c (show_msix), lib/header.h: Added dumping of MSI-X cap.
269 Patch by Roland Dreier <roland@topspin.com>, cleaned up by me.
271 * lspci.c (show_pcix_nobridge, show_pcix_bridge): Handle config_fetch()
274 * lib/header.h: Added PCI Express extended capabilities. Again by Matthew.
276 * lspci.c (show_express): Added dumping of PCI Express cap.
277 Patch by Matthew Wilcox.
279 * lib/header.h: Added a list of PCI 3.0 capabilities and also details
280 on PCI Express caps. Patch by Matthew Wilcox <willy@debian.org>.
282 * lspci.c (check_root): Gone. No explicit checks for root are needed,
283 report correct errors reported by the libpci instead.
285 * lspci.c: Added dumping of the extended config space on "-xxxx".
286 Better caching of config registers.
288 * setpci.c (main): Allow access to whole 4096 bytes of the config space.
290 * lib/sysfs.c, lib/proc.c: Don't print error messages on short reads,
291 just return the appropriate error code.
293 * lib: Added support for extended (4096-byte) configuration space,
294 currently implemented only in Linux proc and sysfs access methods
295 and of course in the dump reader.
297 2004-05-29 Martin Mares <mj@ucw.cz>
299 * Released as 2.1.99-test5.
301 * lib/pci.h: Windows don't have the standard u_int* types.
303 * lib/internal.h: <sys/param.h> required on Windows for endianity
306 * lib/i386-ports.c: Connected i386-io-windows.h.
308 * lspci.c (check_root): geteuid() is not available on Windows.
310 * lib/i386-io-windows.h: Added Windows port contributed by Alexander
311 Stock <stock.alexander@gmx.de>.
313 * lib/configure: Hopefully fixed SunOS port broken by various
314 changes to the configure script.
316 * Makefile, lib/configure: Cross-compilation support, patch by Maciej.
318 2004-05-28 Martin Mares <mj@ucw.cz>
320 * Released as 2.1.99-test4.
322 * lspci.c (show_verbose): Header type 1 is probably legal for all
323 types of bridges, not only for PCI-to-PCI bridges.
325 * lspci.c (format_agp_rate): Write "x16", not "x@".
326 (show_agp): rate[] could overflow.
327 Bugs reported by Jakub Bogusz <qboosh@pld-linux.org>.
329 * lspci.c (show_ht_*): Show HyperTransport capability with all its
330 details. Once again code by Maciej simplified (i.e., possibly broken)
333 * lib/header.h: Added declarations of HyperTransport capability.
334 Again thanks to Maciej.
336 * lspci.c: Decode all bits of the secondary status word in type 1 headers.
337 Thanks to Maciej W. Rozycki <macro@ds2.pg.gda.pl> for the patch.
339 2003-12-27 Martin Mares <mj@ucw.cz>
341 * Released as 2.1.99-test3.
343 * lspci.man, setpci.man: Document domains and correct spelling.
345 * lib/dump.c (dump_init): Added ability to read domain numbers.
347 * lspci.c: Devices in domains different from 0 have their slot number
348 printed as "<domain>:<bus>:<slot>.<func>". Tree view supports domains
351 * lib/filter.c: Slot filters understand domains.
353 * lib/generic.c: Mention the domain in slot numbers in all error messages.
355 * lib/internal.h: The #ifdef for Linux <asm/byteorder.h> was wrong.
357 * lib/access.c (pci_get_dev): Added support for domains.
359 * lib/sysfs.c (sysfs_scan): Read vendor and device ID from the config
360 registers (or to be precise, leave it for the generic parts of the pcilib
361 to do so) instead of reading them from the sysfs. It's faster this way.
363 * lspci.c (show_pcix): Don't touch pci_dev->hdrtype, it's an internal
364 variable. Better read it from the config registers (it's cached anyway).
366 * lib/sysfs.c (sysfs_scan), lib/proc.c (proc_scan): Don't read the hdrtype.
367 lib/generic.c (pci_generic_fill_info): If hdrtype is -1 (unset), read it.
368 Saves lots of unnecessary file accesses.
370 * lib/pci.h (PCIADDR_PORT_FMT): Use %llx instead of %Lx, because the latter
371 is not supported by all C libraries.
373 * Makefile: Always enter the lib directory (remember that we don't have
374 full dependecies for the library in the top-level Makefile; hmmm, another
375 thing to rewrite some day).
377 * lib/sysfs.c: Added Linux sysfs access method based on the patch
378 written by Matthew Wilcox <willy@fc.hp.com>.
380 * lib/proc.c: Renamed the access method name from "/proc/bus/pci" to "Linux-proc".
382 * lib/pread.h: The hacks to support pread on various versions
383 of Linux libc moved there.
385 * lib/proc.c (proc_setup): The return value of snprintf() varies
386 between glibc versions, so we need to check both for a negative
387 values and for too large values.
389 * Removed last few references to the "Linux PCI Utilities", the
390 package is pretty cross-platform now :)
392 2003-12-27 Martin Mares <mj@ucw.cz>
394 * Released as 2.1.99-test2.
396 * README, pciutils.lsm, pciutils.spec: Use @VERSION@ to make the
397 release scripts insert the current version. "make release" is gone.
399 * maint/release, maint/release.pm: Added a new system of scripts for
400 making releases including inter-version diffs etc.
402 * Makefile: Cleaned up.
404 * lib/fbsd-device.c: I patched another copy of this file by mistake,
405 this time the version checks should be right.
407 2003-12-27 Martin Mares <mj@ucw.cz>
409 * Released as 2.1.99-test1.
411 * pciutils.h, common.c, lspci.man, setpci.man, lib/internal.h:
412 Remove shadows of the syscall access method which was never
415 * update-pciids.sh: Try to preserve permissions of the old file
416 if chmod supports --reference. Should close Debian Bug #223740.
418 * lib/proc.c (proc_setup): Increased path name length limit to 1024.
419 Thanks for Redhat and Mandrake for inspiration.
421 * lib/configure: Recognize ppc and ppc64, both have 64-bit addresses.
422 Grabbed from Redhat (Fedora) patches.
424 2003-12-27 Martin Mares <mj@ucw.cz>
426 Merged bug fixes from Debian patches:
428 * lspci.c (show_verbose): "Cache Line Size" should be capitalized.
430 * lspci.c (show_pcix_nobridge): Added a missing newline.
432 * lib/proc.c (proc_scan): When reading the header type, don't
433 forget to clear the topmost bit indicating that the device has
436 2003-12-27 Martin Mares <mj@ucw.cz>
438 Updated the FreeBSD port. Thanks to Samy Al Bahra <samy@kerneled.com>
441 * lib/Makefile: Add ${FREEBSD_SYS} to the include path if it's defined.
442 * lib/fbsd-device.c: Select the right set of system includes according
443 to __FreeBSD_version.
445 2003-12-27 Martin Mares <mj@ucw.cz>
447 Merged support for Solaris on i386 by Bill Moore <billm@eng.sun.com>
450 * lib/configure: Recognize SunOS.
451 * lib/internal.h: Learn how to recognize byte order on SunOS.
452 * lib/i386-ports.c: Split OS-dependent I/O port access from i386-ports.c.
453 * lib/i386-io-linux.h: Linux specific part.
454 * lib/i386-io-hurd.h: GNU/Hurd specific part.
455 * lib/i386-io-sunos.h: SunOS specific part.
457 2003-12-26 Martin Mares <mj@ucw.cz>
459 * lib/header.h (PCI_*_MASK): Cast to pciaddr_t explicitly.
461 * lib/pci.h: Types declared in <sys/types.h> should be usable on all
462 platforms we currently support, so kill the forest of #ifdef's and
463 use them in all cases.
465 * lib/pci.h: Use ULONG_MASK to decide whether we should use long
466 or long long to represent a 64-bit address. Killed HAVE_LONG_ADDRESS.
467 Define format strings for addresses, port numbers and IRQ numbers
470 * lib/proc.c (proc_scan): Use PCIADDR_T_FMT for scanf'ing addresses.
472 2003-12-26 Marco Gerards <metgerards@student.han.nl>
474 Added support for the GNU Hurd (cleaned up by Martin Mares):
476 * lib/configure [GNU]: Use the i386 ports for configuration access.
477 * lib/i386-ports.c: Don't call iopl() on the Hurd.
478 * lib/pci.h [OS_GNU]: Include <sys/types.h> and use it for defining
481 2003-12-26 Martin Mares <mj@ucw.cz>
483 * lspci.c (show_pcix_bridge, show_pcix_nobridge): Don't forget to call
484 config_fetch() to ensure that the registers have been read. Thanks to
485 Bill Wood <bill.wood@hp.com> for the patch.
487 * lspci.c: Ensure that failure of config_fetch() is handled correctly
490 * lspci.man: There was one more explicit reference to /usr/share/pci.ids.
491 Changed to @SHAREDIR@. Patch from Maciej W. Rozycki <macro@ds2.pg.gda.pl>.
493 * setpci.c (main): Better error messages.
495 * setpci.c (ex_op): The demo mode should disable only writing, not reading.
497 * setpci.man: The documentation was inconsistent on what should -D do.
498 Document the new behaviour.
500 * pciutils.h, common.c, setpci.c: Introduced a NONRET macro encapsulating
501 the GCC specific __attribute__((noreturn)) and killed the hack with
502 redefining __attribute__ on non-GCC compilers.
504 * Makefile: Added missing dependencies. Parallel builds work now.
505 Problem reported by Andreas Haumer <andreas@xss.co.at>, but I chose
508 * Makefile (MANDIR): Use `:=' instead of `=' to avoid executing the shell
509 command every time $(MANDIR) is referenced.
511 * lspci.c (main): The error message for `lspci -s' incorrectly mentioned
512 a `-f' switch. Reported by Steve Finney <Steve.Finney@SpirentCom.COM>.
514 * lib/generic.c: Removed memory leak in pci_generic_bus_scan().
515 Reported by Gary Parnes <gary_parnes@terago.com>.
517 * Replaced obsolete syntax of __attribute__((unused)) in the middle of
518 parameter declarations (which is no longer supported by GCC 3.1) by the
519 current syntax (attribute at the end). Thanks to pixel@mandrakesoft.com
520 for reporting this problem.
522 * Removed CVS $Id$ tags from all files.
524 * Makefile: Added some more warnings.
526 * setpci.c: Cleaned up mask/value code.
528 2003-12-08 Thayne Harbaugh <tharbaugh@lnxi.com>
530 * setpci.c: Individual bits to be set can be specified as <value>:<mask>.
532 2003-11-29 Martin Mares <mj@ucw.cz>
534 * Imported the pciutils sources to my Arch repository. Good-bye, CVS.
536 2003-01-04 Martin Mares <mj@ucw.cz>
538 * Released as 2.1.11.
540 * Makefile: Changed configuration of installation directories --
541 all paths are now set at the top of the Makefile instead of being
542 scattered between the installation rules. The default installation
543 now goes always to /usr/local regardless of the OS as most distributions
544 already contain some version of pciutils and we don't want custom
545 installations to interfere with the default ones.
547 * Makefile: Removed a couple of ancient install hacks: we no longer
548 try to avoid overwriting a newer pci.ids file (users are now expected
549 to use update-ids) and we don't try to remove /etc/pci.ids (a long time
550 has passed since the last version which used it).
552 * Makefile: Paths to pci.ids in man pages automatically get the right path.
554 * Added the update-ids utility.
556 * lib: Removed partially implemented "syscall" access method which will
557 probably never be needed.
559 2002-12-27 Martin Mares <mj@ucw.cz>
561 * lib/nbsd-libpci.c: Cleaned up and hopefully made it endian safe.
563 * lib/generic.c (pci_generic_scan_bus): Added work-around for devices with
564 discontiguous numbering of functions. This is already present in the Linux
565 kernel for several years, but I forgot to update pciutils as well.
567 2002-12-26 Martin Mares <mj@ucw.cz>
569 * lib/header.h, lspci.c: Dump AGP3 flags and speeds.
571 * lib/pci.h, Makefile: Removed HAVE_OWN_HEADER_H. Always use our own header,
572 there is no reason to prefer the kernel version.
574 * lib/proc.c (proc_scan): Don't forget to initialize hdrtype.
576 * Added preliminary version of NetBSD support by Quentin Garnier
577 <netbsd@quatriemek.com>.
579 2002-04-06 Martin Mares <mj@ucw.cz>
581 * lspci.c: Mention "-xxx" in the help.
583 2002-03-30 Martin Mares <mj@ucw.cz>
585 * Released as 2.1.10.
587 * Removed pci.ids from the CVS as they are now maintained separately.
588 They are still included in the tarball, but if you are building pciutils
589 from CVS sources or you want to get a newer ID file than the one distributed,
590 just use "make update-ids" to download the most recent snapshot from
593 * Makefile, README: Updated accordingly.
595 * Makefile: Added a couple of maintenance targets.
597 * maint/*: Maintainer's utilities now reside here (present only in CVS,
600 * lib/names.c (parse_name_list): End-of-line comments are no longer
601 supported. Hashes are now perfectly valid in all names and they start
602 a comment only at the start of the line.
604 2002-03-26 Martin Mares <mj@ucw.cz>
608 * Makefile: When the currently installed pci.ids file is newer than
609 the version to be installed, don't overwrite it. Suggested by
610 Jean Delvare <khali@linux-fr.org>.
612 2002-03-24 Martin Mares <mj@ucw.cz>
614 * lspci.c (show_pcix_bridge): Added PCI-X capability display.

689 * lib/pci.h: Added the correct typedefs for AIX.
691 * lib/generic.c (pci_generic_scan_bus): Export.

696 * lspci.c: Avoid using alloca() if not compiled by GCC.
697 (insert_dev): Avoid returning a void value.
699 * Makefile: Choose which install utility to use according to

709 when not compiled by GCC.
711 2000-04-17 Martin Mares <mj@albireo.ucw.cz>
715 * pci.ids: Added a large batch of ID's contributed by Gunther
716 Mayer <gunther.mayer@braunschweig.netsurf.de> and synced the

729 Tue Feb 15 00:16:21 2000 Martin Mares <mj@albireo.ucw.cz>
733 * pciutils.spec: Updated spec file from Andreas Jaeger. Now using
734 %{_mandir} to find the right location to install manual pages to.
738 * setpci.c (main): Don't crash when `-s' or `-d' is given with
741 Mon Jan 24 20:04:11 2000 Andreas Jaeger <aj@suse.de>
743 * lib/i386-ports.c: Include <asm/io.h> only on systems without
746 Mon Jan 24 11:24:43 2000 Martin Mares <mj@albireo.ucw.cz>
748 * Makefile: Modified to work with the Linux FHS brain-damaged idea
749 of putting man pages to /usr/share/man. Now we choose either /usr/man
750 or /usr/share/man depending on which one exists.
752 Sun Jan 23 10:52:34 2000 Martin Mares <mj@albireo.ucw.cz>
754 * pci.ids: Synced with Linux 2.3.40.

764 * lspci.c (format_agp_rate): Better formatting of AGP rates.
768 * lib/configure: Added configuration for ia64 (the same as for Alpha).
769 Patch from Stephane Eranian <eranian@cello.hpl.hp.com>.
771 Thu Jan 13 23:01:52 2000 Martin Mares <mj@albireo.ucw.cz>
773 * Released as version 2.1.3.
777 * lspci.c: Alpha IO_FORMAT fix by Andrea Arcangeli.
779 * lib/access.c: Corrected order of access methods -- it's wonderful how
780 long could such a bug remain unspotted. Thanks go to Andreas Schockenhoff.
782 Sat Dec 11 23:34:48 1999 Martin Mares <mj@albireo.ucw.cz>
784 * Released as version 2.1.2.
786 * lib/names.c (pci_lookup_name): Fixed printing of unknown subsystem ID's.
788 Sat Dec 4 13:11:03 1999 Martin Mares <mj@albireo.ucw.cz>
790 * Released as version 2.1.1.
792 * pci.ids: Several new ID's.
794 * setpci.c (exec_op): Don't forget to increment address after writing
795 single value, so that `30.b=12,34,56,78' works as expected. Reported
796 by Petr Soucek <petr@ryston.cz>.
798 Wed Nov 3 10:24:38 1999 Martin Mares <mj@albireo.ucw.cz>
800 * lspci.c (show_terse): If prog-if is zero, but it's present in the

805 * Released as version 2.1.
807 * pci.ids: Synced to devlist.h in 2.3.24 kernel. Merged in
808 lots of contributed entries.
810 Thu Oct 14 10:40:12 1999 Dave Jones <dave@powertweak.com>
812 * pci.ids: Added lots of subsystem definitions.
814 Sat Oct 9 14:32:28 1999 Martin Mares <mj@albireo.ucw.cz>
816 * setpci.man: Better example.
818 * lspci.c: Resolve prog-if names.
820 * lib/names.c: Adapted to new pci.ids syntax.
822 * pci.ids: Reorganized the pci.ids file. Subsystems are listed
823 under devices, classes can optionally contain prog-if information.
824 New ID's, as usually.
826 Wed Sep 22 09:45:24 1999 Martin Mares <mj@albireo.ucw.cz>
828 * pci.ids: New ID's. As usually.
830 * lspci.c (show_htype1, show_htype2): Don't show `closed' bridge windows
831 unless we're vvvery verbose.
833 Mon Sep 20 11:22:54 1999 Martin Mares <mj@albireo.ucw.cz>
835 * lspci.c (show_htype2): Don't forget a TAB before the "I/O window" line.
837 Tue Sep 14 09:31:01 1999 Martin Mares <mj@albireo.ucw.cz>
839 * pci.ids: New ID's. Again.
841 Thu Aug 5 17:45:42 1999 Martin Mares <mj@albireo.ucw.cz>
843 * lspci.c (show_size): Don't show size if it's zero (usually
844 due to bus-centric mode being enabled).
846 Tue Jul 20 13:25:09 1999 Martin Mares <mj@albireo.ucw.cz>
848 * lib/pci.h: Types are OS dependent.
850 * lib/internal.h: Byte order hacks are OS dependent.
852 * lib/configure: Recognize FreeBSD. Also set OS_XXX according to the OS.
854 * lib/Makefile, lib/access.c: Added fbsd-device target.
856 * pci.ids: Added an entry for PLX 9080 bridges with subsystem ID
857 incorrectly set to device ID.
859 * README: Added a note that we support FreeBSD.
861 * Makefile (PREFIX, ROOT): Set it depending on the OS.
862 (%.8): Grrr, BSD date is not able to convert date formats the same way
863 as GNU date does. Use sed instead.
864 (install): Use `-c' when calling install.
866 * lib/fbsd-device.c: Added FreeBSD /dev/pci access module contributed
867 by Jari Kirma <kirma@cs.hut.fi>.
869 * lib/proc.c: Rewrote the pread/pwrite things once again. Use pread
870 and pwrite only when we are certain it's safe (i.e., glibc 2.1
871 on all architectures or any libc on a i386 where we really know
872 how to use syscalls directly). In all other cases, emulate it
873 with lseek/read/write.
875 * pci.ids: Some more IDs.
877 Mon Jul 19 14:10:36 1999 Martin Mares <mj@albireo.ucw.cz>
879 * pci.ids: Added IDs of parallel port controller cards as sent
880 by Tim Waugh <tim@cyberelk.demon.co.uk>.
882 Wed Jul 7 00:55:48 1999 Martin Mares <mj@albireo.ucw.cz>
884 * lib/proc.c (proc_scan): HAVE_LONG_ADDRESS instead of HAVE_64BIT_ADDRESS.
886 * lspci.c: ADDR_FORMAT now depends on both HAVE_64BIT_ADDRESS and
889 * lib/configure: HAVE_64BIT_ADDRESS now doesn't imply that the addresses
890 are represented as long long. Introduced a new flag HAVE_LONG_ADDRESS
891 to indicate this. Both Sparc architectures now use both 64BIT_ADDRESS
892 and LONG_ADDRESS since they have 32-bit userland, but don't set LONG_ADDRESS
895 * lspci.c (show_msi): Added dumping of the MSI capability.
896 (show_slotid): The same for SlotID capability.
897 (show_caps): Seperated capability dumping, because it should
898 be used for both htype0 and htype1. Even PCI 2.2 doesn't mention
899 layout of htype2, so I'm a bit unsure about it wrt capabilities
900 -- they at least have to live somewhere else since address 0x34
901 is already defined differently in htype2.
903 * lib/header.h (PCI_STATUS_UDF): Marked as obsolete (PCI 2.2).
904 (PCI_BASE_ADDRESS_MEM_TYPE_1M): Ditto.
905 (PCI_CAP_ID_*): Added some new capabilities defined in PCI 2.2.
907 * lspci.c (show_htype0): Mask out lowest 2 bits from all capability pointers
908 (required by the PCI 2.2 specs).
910 Mon Jul 5 12:45:19 1999 Martin Mares <mj@albireo.ucw.cz>
912 * lspci.c (show_size): Added new function for dumping of region sizes.
913 (show_rom): Added. Now correctly dumps unassigned ROM addresses, disabled
916 * lib/pci.h (struct pci_dev): known_fields moved to the public part
919 * Added support for region sizes. Needs support in the kernel, because
920 sizes have to be scanned before drivers initialize yourself. pci_fill_info()
921 now returns a bitmask of what fields were really read.
923 Mon Jun 28 18:37:51 1999 Dave Jones <dave@powertweak.com>
926 Added `uninstall' target - removes all traces of pciutils.
928 - Lots of cleanups in the ATI, S3, Adaptec vendors.
929 - Changed Compaq QVision 1280/p definitions, as it's not possible
930 to determine the revision from the device ID.
931 - Same for the Tseng ET4000.
932 The id's said I had a rev C, when it was actually a rev B.
933 - Removed some unnecessary strings
934 `PCI'. Unless it's an AGP card, it should be obvious that it's PCI.
935 `Ethernet card'. This should be determined from config space.
936 - Lots of other new vendors & devices
937 - Other additional small cleanups.
939 Mon Jun 21 22:11:10 1999 Martin Mares <mj@albireo.ucw.cz>
941 * lib/names.c (pci_lookup_name): When device ID lookup
942 fails, return hexadecimal device ID instead of vendor ID.
943 Well spotted by Axel Bodemann <Axel.Bodemann@ruhr-uni-bochum.de>,
944 I've just extended the fix to subsystem ID's.
946 Thu Jun 17 19:48:21 1999 Martin Mares <mj@albireo.ucw.cz>
948 * lspci.c (show_agp): Bug fix from Petr Vandrovec
949 <vandrove@vc.cvut.cz>. The command register was displayed
952 Wed Jun 2 22:42:44 1999 Martin Mares <mj@albireo.ucw.cz>
954 * lib/proc.c (SYS_pread, SYS_pwrite): Use hard-coded
955 numbers if not supplied by the libc.
957 Wed May 19 13:24:39 1999 Martin Mares <mj@albireo.ucw.cz>
959 * Released the whole package as version 2.0.
961 Fri May 14 22:42:02 1999 Martin Mares <mj@albireo.ucw.cz>
963 * pci.ids: Added several new ID's contributed by people
964 on the linux-pci list.
966 Mon Apr 19 15:21:08 1999 Jakub Jelinek <jj@ultra.linux.cz>
968 * lspci.c: Display I/O addresses correctly on sparc64.
969 * lib/header.h: Ditto.
971 * lib/configure: On sparc set HAVE_64BIT* as well, we want
972 a binary which works on both 32bit and 64bit SPARCs.
974 Sun Apr 18 21:14:58 1999 Martin Mares <mj@albireo.ucw.cz>
976 * lspci.c, lib/proc.c: Alpha compilation fixes from Matthew Jacob
979 * pci.ids: A lot of updates from Adam J. Richter <adam@yggdrasil.com>.
981 Sun Feb 28 22:26:21 1999 Martin Mares <mj@albireo.ucw.cz>
983 * lspci.c (do_map_bus): Don't dump functions 1--7 if not flagged
984 as a multi-function device, because several single-function devices
985 don't decode the function bits at all.
987 Sun Feb 14 23:48:22 1999 Martin Mares <mj@albireo.ucw.cz>
989 * Makefile (install): Don't use "-o root -g root" for installation
990 since it breaks on machines where programs are not installed by root.
991 Reported by Richard Gooch <rgooch@atnf.csiro.au>
993 Tue Feb 9 15:54:39 1999 Martin Mares <mj@albireo.ucw.cz>
995 * lspci.c (show_bases): Use new address masking macros and pciaddr_t.
997 * lib/pci.h: Using pciaddr_t for bus addresses, which are 32-bit
998 or 64-bit depending on CPU.
1000 * lib/pci.h (PCI_ADDR_MEM_MASK): Added macros for address masks
1001 according to bus address width.
1003 Thu Jan 28 20:54:16 1999 Martin Mares <mj@albireo.ucw.cz>
1005 * Released as 1.99.4.
1007 * lspci.c: Capability list parser now recognizes both AGP
1008 registers and PCI Power Management registers (the latter
1009 is mainly guesswork based on DEC/Intel 21153 bridge specs
1010 since I don't have the PCI Power Management document).
1012 * lspci.c: Replaced numerous occurences of (x & flag) ? '+' : '-'
1015 * lspci.c: Added bridge checks to bus mapping code.
1017 Wed Jan 27 14:59:16 1999 Martin Mares <mj@albireo.ucw.cz>
1019 * lspci.c: Implemented bus mapping mode (-M).
1021 * lspci.c (scan_devices): Split to scan_devices() and scan_device().
1022 (show): Split to show() and show_device().
1024 * lib/access.c (pci_init): When a->method == PCI_ACCESS_AUTO,
1025 set it to the real access method afterwards.
1027 Mon Jan 25 23:46:13 1999 Martin Mares <mj@albireo.ucw.cz>
1029 * lib/generic.c (pci_generic_fill_info): If in buscentric mode,
1030 don't check PCI_COMMAND for I/O and memory enables.
1032 Mon Jan 25 21:28:49 1999 Martin Mares <mj@albireo.ucw.cz>
1034 * Makefile: Added target `release' which substitutes new version
1035 number to .spec, .lsm and README. Also rewrote target `dist'.
1037 * Released as 1.99.3.
1039 Sun Jan 24 22:10:36 1999 Martin Mares <mj@albireo.ucw.cz>
1041 * lib/header.h: Until kernel adopts new layout of PCI
1042 includes (i.e., separate declaration of header structure,
1043 functions and device IDs), which is not going to happen
1044 before 2.3, we'll use our own definiton of the header.
1046 * lspci.c (show_verbose): Display `Cap' flag in device status.
1048 * lspci.c (show_htype0): Display capability lists whereever
1049 available. The only capability name we recognize now is `AGP'.
1050 Unfortunately, capabilities are stored in device-dependent
1051 portion of the configuration space and are thus available
1052 only to root unless you read a dump.
1054 * lspci.c (scan_devices): Use cache instead of buffering.
1056 * lib/buffer.c: Removed (obsoleted by the cache).
1058 * lib/access.c: Added general caching mechanism.
1060 Sat Jan 23 21:30:54 1999 Martin Mares <mj@albireo.ucw.cz>
1062 * pci.ids: Added few devices.
1064 Fri Jan 22 19:29:31 1999 Martin Mares <mj@albireo.ucw.cz>
1066 * Version string is now defined in top-level Makefile, exported
1067 to the configure script and also substituted to man pages.
1069 * lspci.c (show_bases): Rewrote displaying of 64-bit addresses.
1070 (show_verbose): Rewrote interrupt display logic.
1072 * lib/i386-ports.c: Include sys/io.h only on glibc systems.
1074 * lib/configure: Rewrote detection of Linux versions. Now it
1075 works on 2.0 kernels (only with direct/dump access, of course).
1077 * lib/internal.h: New bytesex macros using <asm/byteorder.h>
1080 * lib/proc.c (proc_read, proc_write): Distinguish between short
1081 read/write and real errors.
1083 * lspci.c (show_htype{0,1}): Always use d->dev->rom_base_addr since
1084 libpci respects buscentric mode automatically.
1086 * lspci.c (show_hex_dump): For CardBus bridges, print out 128
1087 bytes of header (the whole standard part).
1089 * common.c: pcilib options are now all uppercase. Also moved
1090 PCI access debugging option here.
1092 * Released as 1.99.2.
1094 Wed Jan 20 22:50:35 1999 Martin Mares <mj@albireo.ucw.cz>
1096 * Wrote configure script and rewrote Makefiles.
1098 * Removed few unused variables.
1100 Wed Jan 20 12:21:56 1999 Martin Mares <mj@albireo.ucw.cz>
1102 * common.c: Moved several functions used in both setpci and lspci
1103 here. This includes parsing of libpci-related options.
1105 * More library tweaks.
1107 * filter.c, names.c: Moved to library.
1109 * setpci: Rewritten to use the library.
1111 * Released as 1.99.1.
1113 Tue Jan 19 23:00:12 1999 Martin Mares <mj@albireo.ucw.cz>
1115 * lspci.c (scan_devices): For cardbus bridges, read first 128
1116 bytes of config space to get full standard header.
1118 * Makefile (CFLAGS): Removed "-Wno-unused".
1120 * Started the "New Generation" branch and introduced the
1123 * lspci: Rewritten to use the library.
1125 Tue Jan 19 22:24:08 1999 Martin Mares <mj@albireo.ucw.cz>
1127 * Released as version 1.10.
1129 Mon Jan 18 08:51:17 1999 Martin Mares <mj@albireo.ucw.cz>
1131 * lspci.8, setpci.8: Miscellaneous fixes as suggested by
1132 Dag Wieers <dag@digibel.be>.
1134 Sun Nov 29 20:05:56 1998 Martin Mares <mj@albireo.ucw.cz>
1136 * pciutils.spec (Name): Update from Krzysztof G. Baranowski.
1138 Sun Nov 22 10:49:56 1998 Martin Mares <mj@albireo.ucw.cz>
1140 * Makefile, pciutils.h: Moved pci.ids to /usr/share.
1142 * Released as version 1.09.
1144 Wed Nov 18 15:47:05 1998 Martin Mares <mj@albireo.ucw.cz>
1146 * lspci.c (show_htype1): Fixed displaying of prefetchable memory behind
1147 bridge. Thanks to Petr Vandrovec <vandrove@vc.cvut.cz> for bug report.
1149 Fri Oct 23 18:59:19 1998 Martin Mares <mj@albireo.ucw.cz>
1151 * setpci.c: Don't include <syscall-list.h> with glibc >= 2.1.
1153 Mon Oct 19 21:53:30 1998 Martin Mares <mj@albireo.ucw.cz>
1155 * Released as version 1.08.
1157 * setpci.c: glibc 2.1.x already defines pread() and pwrite().
1159 * lspci.8: Changed warning about lspci -xxx.
1161 * lspci.c: Require "-xxx" for full configuration space dump, so that
1162 it's impossible to crash the machine by single typo.
1164 * specs: Added (courtesy of Krzysztof G. Baranowski <kgb@knm.org.pl>).
1166 Wed Sep 9 12:03:24 1998 Martin Mares <mj@albireo.ucw.cz>
1168 * lspci.c (show_bases): Better displaying of unassigned and
1169 disabled bases. Thanks to Gabriel Paubert <paubert@iram.es>
1172 Wed Sep 2 10:58:01 1998 Martin Mares <mj@albireo.ucw.cz>
1174 * setpci.c (pread): Recognize glibc 1.99 numbered as 2.0 on the PPC.
1175 (thanks to Geert Uytterhoeven for finding this out)
1177 Fri Jul 17 10:43:30 1998 Martin Mares <mj@albireo.ucw.cz>
1179 * lspci.c (show_verbose): Print subsystem ID using the new resolver.
1180 (show_machine): Print subsystem ID.
1182 * names.c: New name resolution engine supporting subsystem IDs.
1184 * Released as version 1.07.
1186 Wed Jul 15 15:37:21 1998 Martin Mares <mj@albireo.ucw.cz>
1188 * lspci.c (show_htype2 etc.): Displaying of CardBus headers.
1189 (show_bases): Honor the `cnt' argument.
1190 (grow_tree): Parse CardBus headers in tree mode as well.
1192 * pci.h: Updated CardBus header field description. I still don't
1193 have the CardBus standard available, but OZ6832 specs contain
1194 full description of all header fields supported by the chip.

1200 * names.c (parse_name_list): Killed an unused variable.
1202 * setpci.c (pread, pwrite): Define SYS_(pread|pwrite) as __NR_\1
1203 if they are not defined by glibc (needed for glibc built on older
1206 * setpci.c (exec_op): Fixed error messages. Thanks, Steve!
1208 Mon Jun 8 10:59:22 1998 Martin Mares <mj@albireo.ucw.cz>
1212 * setpci.c: Problems with pread()/pwrite() with glibc on Alpha
1213 should be gone. Again thanks to Steve for bug report.
1215 * filter.c (filter_parse_slot): Fixed ":x" type filters.
1217 * pci.ids: Killed duplicate entry. Thanks to Stephen Williams
1218 <steve@icarus.com> for reporting this.
1220 Sun Jun 7 19:27:51 1998 Martin Mares <mj@albireo.ucw.cz>
1222 * lspci.c (main), setpci.c (main): Implemented "--version".
1226 * pciutils.h (PCIUTILS_VERSION): Added version string.
1228 * filter.c, names.c: Extraneous #include <linux/pci.h> removed.
1229 Thanks to Geert Uytterhoeven <Geert.Uytterhoeven@cs.kuleuven.ac.be>
1232 Thu May 28 14:45:58 1998 Martin Mares <mj@lomikel.karlin.mff.cuni.cz>
1234 * pci.ids: More updates from Jens Maurer.
1236 Wed Apr 22 10:00:39 1998 Martin Mares <mj@albireo.ucw.cz>
1238 * pci.ids: Updates from Jens Maurer.
1240 Sun Apr 19 11:14:25 1998 Martin Mares <mj@albireo.ucw.cz>
1244 * setpci.8: Written.
1246 * setpci.c: Finished.
1248 * lspci.c: Now able to fetch expansion ROM base from kernel device list
1249 and print it if not in buscentric mode.
1251 Tue Mar 31 23:11:57 1998 Martin Mares <mj@albireo.ucw.cz>
1255 Sun Mar 22 15:39:08 1998 Martin Mares <mj@albireo.ucw.cz>
1257 * lspci.8: Updated the documentation.
1259 * lspci.c: Modified to use the new filtering mechanism (options -f and -d).
1261 * filter.c: Introduced new generic device filter.
1263 Thu Mar 19 17:03:48 1998 Martin Mares <mj@lomikel.karlin.mff.cuni.cz>
1265 * lspci.c (grow_tree, show_tree_dev, print_it): Fixed displaying
1266 of PCI-to-PCI bridges in the tree format.
1268 Sun Feb 15 10:12:25 1998 Martin Mares <mj@albireo.ucw.cz>
1270 * lspci.c (show_machine): Added non-verbose mode of machine-readable
1273 * pci.ids: Updates from Jens Maurer.
1275 * Released as version 1.02.
1277 Thu Feb 12 16:53:28 1998 Martin Mares <mj@lomikel.karlin.mff.cuni.cz>
1279 * lspci.c: Added a "-m" switch for dumping machine-readable
1280 configuration data (requested by Bjoern Kriews <bkr@cut.de>).
1282 Mon Feb 9 13:17:43 1998 Martin Mares <mj@albireo.ucw.cz>
1284 * Makefile, pciutils.h: Include local pci.h instead of <linux/pci.h>
1285 if available. This should avoid all problems with official kernel
1286 not synchronized to newer PCI code in CVS -- standard distribution
1287 of pciutils now contains pci.h from current CVS kernel, pciutils
1288 in CVS contain no pci.h and use the correct kernel include.
1290 * Makefile: Fixed installation path for man pages.
1292 Sat Feb 7 15:15:46 1998 Martin Mares <mj@albireo.ucw.cz>
1296 * lspci.8: Created a man page.
1298 * Releasing as version 1.0.
1300 Tue Feb 3 20:56:00 1998 Martin Mares <mj@albireo.ucw.cz>
1302 * Makefile: Recognize architecture by calling uname and pass it as ARCH_xxx
1303 to all the C sources. This should eliminate problems with 32-bit compilers
1306 * lspci.c (show_verbose): Recognize CardBus bridge header type.
1307 (show_htype2): Stub routine.
1308 (scan_config): Write sensible error message if the kernel denies reading of
1309 upper part of the PCI config space.
