Internally, the implementation was rewritten, + significantly reducing the number of corner cases to be handled. + + * The Windows port was revived and greatly improved by Pali Rohár. + It requires less magic to compile. More importantly, it runs on both + old and recent Windows systems (see README.Windows for details). + + * Added a new Windows back-end using the cfgmgr32 interface. + It does not provide direct access to the configuration space, + but basic information about the device is reported via pci_fill_info(). + For back-ends of this type, we now provide an emulated read-only + config space. + + * If the configuration space is not readable for some reason + (e.g., the cfgmgr32 back-end, but also badly implemented sleep mode + of some devices), lspci prints only information provided by the OS. + + * The Hurd back-end was greatly improved thanks to Joan Lledó. + + * Various minor bug fixes and improvements. + + * We officially require a working C99 compiler.

This + involved major internal cleanup. + + * The above feature of setpci uses the pci_get_dev() function, + which obtains a struct pci_dev without doing a bus scan. This was + always possible, but apparently little used, because back-ends + frequently choked when operating on such devices. Fixed a lot + of minor bugs related to this. + + * Also, back-ends which do not support domains now correctly fail when + trying to access devices outside domain 0. + + * Semantics of pci_fill_info() and pci_dev->known_fields was underspecified, + which lead to inconsistencies between back-ends. Improved documentation + to give a more precise definition and updated all back-ends to conform + to it. Most importantly, pci_dev->known_fields shows all fields requested + over the lifetime of the pci_dev, but never those which are not supported + by the back-end. + + * As usually, updated pci.ids to the current snapshot of the database. + +2020-01-25 Martin Mares + + * Released as 3.6.4. + + * A new back-end for the GNU Hurd was contributed by Joan Lledó. + + * When printing VPD item identifiers, non-ASCII characters are escaped. + +2020-01-22 Martin Mares + + * Released as 3.6.3. + + * `lspci -t' (tree mode) can be combined with `-s' to show a sub-tree. + We also fixed potential buffer overflows in the tree dumper. + + * Cleaned messy code for dumping of I/O, memory, and ROM regions. + This helped fixing a bug, which caused some 64-bit regions to be + reported as virtual.
