2009-02-01  Martin Mares <[e-mail]>

	* Released as 3.1.2.

	* Fixed another silly bug in the command-line parser of setpci.

2009-01-30  Martin Mares <[e-mail]>

	* Released as 3.1.1.

	* Updated pci.ids to the current snapshot of the database.

	* The configure script now sets LC_ALL to avoid being fooled by
	locale-dependent behavior of `tr'.

	* The command-line parser of setpci did sometimes segfault on invalid
	input. Thanks to Andreas Wiese for a fix.

2009-01-18  Martin Mares <[e-mail]>

	* Released as 3.1.0.

	* Updated pci.ids to the current snapshot of the database.

	* The Cygwin backend now works on Windows Vista. Thanks to Jonathan
	Kotta.

	* Fixed a bug in decoding of the SR-IOV capability. Patch by Yu Zhao.

	* Details of some PCIe capabilities are displayed only with -vv.

	* When a BAR is reported by the OS, but not by the device (i.e.,
	it is marked as [virtual] in lspci), the [disabled] flag is
	suppressed, because it does not make sense in such cases.
	Patch by Yu Zhao.

2008-12-13  Martin Mares <[e-mail]>

	* The source code of lspci has been split to multiple files, hopefully
	making it easier to maintain.

	* The library and lspci now know about physical slot names. So far,
	they are provided by the sysfs back-end only. Thanks go to Alex Chiang.

	* When a device has the VPD (Vital Product Data) capability and the
	VPD data are supplied by the OS, they are decoded and printed in the
	verbose mode. This currently works only on Linux with the sysfs
	back-end. Thanks to Ben Hutchings of Solarflare for the patch.

	* `setpci --version' now works properly.

	* `setpci --dumpregs' prints a table of all known names of
	registers and capabilities. This replaces the table of registers
	in the setpci man page.

	* The dry-run mode of setpci gives better feedback.

	* The setpci utility is now able to address registers stored in PCI
	capabilities (actually it allows a more general form of relative
	addressing).

	* The library has gained functions for working with PCI capabilities.

	* Address Translation Services capability is now decoded. Patch by
	Yu Zhao.

2008-11-09  Martin Mares <[e-mail]>

	* Released as 3.0.3.

	* `lspci -k' now displays the subsystem ID, too. This makes `-k'
	show everything needed to identify the device and the available
	drivers, which was called for by many users.

	* Fixed spelling of MSI. Patch by Matthew Wilcox.

	* Better support for cross-compilation. Thanks to Alon Bar-Lev
	for the patch.

	* Fixed printing of the AER capability. Patch by Max Asbock.

	* HT 1.02 capabilities are decoded as HT 1.03. Suggested by
	Carl-Daniel Hailfinger.

	* Fixed Cygwin build. Thanks to Steve Elliott for reporting the bug.

	* Updated pci.ids to the current snapshot of the database.

2008-09-19  Martin Mares <[e-mail]>

	* Released as 3.0.2.

	* Fixed a minor bug in the configure script, which caused warnings
	about redefinition of symbols during compilation.

2008-09-11  Martin Mares <[e-mail]>

	* Released as 3.0.1.

	* Updated pci.ids to the most recent snapshot.

	* Added a Cygwin port. Patch by Christopher Voltz, ported to the
	current tree by Martin Mares.

	* Worked around compatibility problems with various default settings
	of wget (we have to set --no-timestamping explicitly). Thanks to Ville
	Skytta for pointing that out.

	* Fixed printing of MSI capabilities. Thanks to Matthew Wilcox for
	a patch.

	* Added decoding of several PCI-X capabilities: device/link/slot 2,
	Advanced Error Reporting, Access Control Services, Alternative Routing-ID,
	Single Root I/O Virtualization. Thanks to Yu Zhao for patches.

	* Fixed bug in filters which caused them to refuse vendor/device ID 0xffff.

	* README: The linux-pci mailing list has moved to [e-mail].

	* Fixed several build problems: builds without PCI_USE_DNS on Linux
	and with PCI_USE_DNS on Solaris and *BSD. Static library mode also
	compiles again on old versions of GCC.

2008-04-10  Martin Mares <[e-mail]>

	* Released as 3.0.0.

	* Updated API and ABI version.

2008-02-20  Martin Mares <[e-mail]>

	* Released as 2.99.1-alpha2.

	* Changed the default domain for the DNS resolver.

2008-02-18  Martin Mares <[e-mail]>

	* Released as 2.99.1-alpha1.

	* The makefile system has been reworked. All configuration settings
	are now passed to the configure script in environment variables,
	allowing for easy tweaking in the top-level Makefile. All control
	knobs are now described in the README.

	* The libpci can be built as a shared library with properly restricted
	symbol exports. Use `make SHARED=yes' to enable that or `make SHARED=local'
	for a local testing build (with hardwired paths to the library, so that
	it does not need installation).

	* The example program has been moved from lib/example.c to the top-level
	directory, because it should be built exactly as the other utilities
	are. It has been also improved slightly to educate better.

	* The i386-ports method is enabled on Linux/x86_64 as well.

2008-02-13  Martin Mares <[e-mail]>

	* Released as 2.2.10-net2.

	* Support for resolving of PCI ID's using DNS together with a local
	cache of resolved entries has been added. See the `-q' and `-Q' options
	of lspci.

	* The library now has a generic system of settable parameters, which
	also include settings of the DNS resolver and cache. An `-O' option
	has been added to lspci and setpci to allow setting of these options.

	* Configuration of the access methods are now specified by the new
	parameter system, replacing the pci_access->method_params array.

	* Access methods now also have sensible names and help texts and it
	is possible to look up method ID by a name.

	* An `-A' switch has been added to both lspci and setpci, allowing to
	select an arbitrary access method. The `-P' switch (configure proc
	backend) has been removed as it is no longer needed and I do not know
	any its user.

	* Several source files have been split for better maintainability
	(most notably the resolving of ID's).

	* Man pages and help texts have been updated. A new man page `pcilib(7)'
	has been added and description of library options has been moved there.

	* When an unknown device ID is encountered, we print `Device <id>'
	instead of `Unknown device <id>'. It uses less space and it also
	should reduce the number of inexperienced users complaining that
	the device is not supported by the OS. To lookup up OS drivers,
	use the `-k' option.

	* PCI_LIB_VERSION has been bumped to 0x020299.

	* Makefile: stripping of the binaries during installation can be
	overridden by the STRIP variable.
	
	* lib/types.h: We use the integer types from <stdint.h> if the
	compiler claims C99 support.

2008-02-11  Martin Mares <[e-mail]>

	* Released as 2.2.10.

	* lspci.c, setpci.c: Cleaned up the list of options.

	* lib/names.c: Fix displaying of errors reported by zlib.
	Previously, the buffer containing the error message had
	been deallocated by gzclose() before the message was printed.

2008-01-07  Martin Mares <[e-mail]>

	* update-pciids.sh: Added quiet mode (-q). Clean up uncompressed
	files left by previous versions of the pciutils. Patch by Mike
	Frysinger.

	* update-pciids.man: Mention the -q switch.

2007-11-29  Martin Mares <[e-mail]>

	* lib/dump.c: Squashed compiler warnings about code with
	no effect (there really were surplus *'s).

2007-11-06  Martin Mares <[e-mail]>

	* Released as 2.2.9.

	* lspci.c: Added a new switch `-k' which requests printing
	of information on kernel drivers attached to each device
	and on kernel modules reporting the ability to handle the
	device. So far, this is supported only on Linux with the
	sysfs back-end, so it is implemented internally in the lspci
	instead of the libpci. Thanks to Anicka <[e-mail]>
	for help.

2007-10-19  Martin Mares <[e-mail]>

	* Makefile, lib/Makefile: Moved -lz from LDFLAGS to LDLIBS.
	Also added an explicit pattern rule for linking to make sure
	that LDLIBS is used on all platforms. Thanks to Dan Nicholson
	for the suggestion.

2007-10-19  Martin Mares <[e-mail]>

	* Released as 2.2.8.

	* pci.ids: Revised class codes to match Conventional PCI 3.0 specs.
	Added a couple of new ones, renumbered `ADMA continuous operation'
	prog-if to 0x30 (even the old SATA Class Code ECN doesn't mention
	0x40) and renumbered the satellite communication controllers.

	* lib/header.h: Include `PCI hot-plug' and `Secure device'
	capabilities from PCI 3.0 specs. Also added `SATA HBA' and
	`Advanced features' caps from various ECN's.

	* lspci.c: All known capabilities have at least their name displayed
	now. When we are unable to decode them completely, we signalize it
	with a `<?>' mark.

	* lspci.man: Document `<?>' and also mention that extended config
	space is currently available only with the linux_sysfs back-end.

	* lspci.c: Decode the Debug port capability (per EHCI 0.96 spec).

	* lspci.c: Big code cleanup: re-arranged functions in the code,
	renamed everything related to capabilities to cap_* and
	all options except verbose to opt_*.

2007-10-14  Martin Mares <[e-mail]>

	* lib/[fno]bsd-*: Removed extraneous braces.

2007-10-12  Martin Mares <[e-mail]>

	* Capability loop detection introduced 2.2.7 did not work
	  properly with extended capabilities. Fixed.

2007-10-05  Martin Mares <[e-mail]>

	* Released as 2.2.7.

	* lspci.c (show_caps, show_ext_caps): Detect and report loops in
	capability lists.

	* lspci.c, lib/header.h: Finished decoding of the PCI Express
	capability. The extended capabilities remain undecoded for now,
	but at least the list of them has been updated to reflect the
	current PCI Express 2.0 spec.

	* lspci.c, lib/header.h: Decode new bits of traditional registers
	as defined by PCIE / PCI-X. This includes discard timers in the bridge
	control register and INTx enable/status in device control/status
	registers.

	* lib/fbsd-device.c: Support domains on new FreeBSD's. Contributed
	by Marius Strobl.

2007-09-12  Hasso Tepper <[e-mail]>

	* Extended the fbsd-device backend to run on Dragonfly BSD.

	* lspci.c: alloca() is declared in <stdlib.h> on BSD's, not <alloca.h>.

2007-09-03  Martin Mares <[e-mail]>

	* Resurrected the Windows port, including cross-compilation by MinGW.
	Patch by Samuel Bronson <[e-mail]>.

2007-08-31  Martin Mares <[e-mail]>

	* Makefile, lib/Makefile: `ar' and `ranlib' can be overriden to allow
	cross-compilation.

2007-08-27  Martin Mares  <[e-mail]>

	* lib/names.c (pci_open): When calling gzopen(), use "rb" file mode
	instead of "r". This is needed on DOS systems, where this function
	somewhat illogically uses the binary flag for the compressed file
	instead of the decompressed stream inside, where binariness really
	matters.

2007-08-14  Martin Mares  <[e-mail]>

	* lspci.c (show_ht): Added decoding of Hypertransport MSI mapping capability,
	based on a patch by Jason Gunthorpe.

	* tests/cap-MSI-mapping: Added a test case. I plan to add test cases
	(which are dumps of config space) for all new features.

2007-06-20  Martin Mares  <[e-mail]>

	* Released as 2.2.6.

	* Makefile: Added an "install-lib" target. Thanks to Dan Nicholson
	for a patch.

	* Makefile, lib/Makefile: Generate and install pkg-config file
	for libpci. Again by Dan Nicholson.

2007-06-20  Thomas Schwinge  <[e-mail]>

	* lib/i386-io-hurd.h: Rewritten for new Hurd kernels.

2007-05-04  Martin Mares  <[e-mail]>

	* Released as 2.2.5.

	* pci.ids: Updated to the current snapshot of the database.

2007-02-14  Martin Mares  <[e-mail]>

	* lspci.c (show_express): Added PCI/PCI-X to PCI-Express Bridge type.
	Patch by Mark Glines.

2007-02-09  Martin Mares  <[e-mail]>

	* pci.ids: Updated to the current snapshot of the database.

2007-02-06  Martin Mares  <[e-mail]>

	* Replaced bzero() by memset() everywhere, it's better to lose a tiny
	bit of readability than maintain hacks to make it work on various systems.

	* lib/configure: tr on Solaris is a bit weird and it requires `[A-Z]'
	instead of `A-Z'. Fortunately, the extra brackets don't hurt otherwise.

	* lib/types.h, lib/configure: Solaris should use <stdint.h> to get precise
	integer types.

2007-02-04  Martin Mares  <[e-mail]>

	* lspci.c: alloca() needs <alloca.h>.

2006-09-17  Martin Mares  <[e-mail]>

	* lib/dump.c: Fixed a couple of bugs in the dump backend which caused
	devices with domains or with extended config space to be read incorrectly.
	Also, dumps with partial lines are allowed now.

2006-09-10  Martin Mares  <[e-mail]>

	* pci.ids: Updated to the current database snapshot.

	* lspci.c (scan_device): If an error occurs when reading the standard config
	header of a device, report it and ignore the device and return with exit
	code 2 at the end.

2006-09-09  Martin Mares  <[e-mail]>

	* Released as 2.2.4.

	* maint/release: Remind the maintainer about the current PCI_LIB_VERSION.

	* lib/pci.h: Updated PCI_LIB_VERSION.

	* lspci.c (show_machine): In the `-m' mode, do proper shell escaping
	if the fields printed contain quotes or backslashes.

	* lspci.c (show_machine): Added a `-vmm' mode, which removes the misuse
	of the `Device' tag for two different purposes.

	* Makefile: Moved all system-dependent decisions to lib/configure,
	since config.mk is included in the top-level Makefile anyway.

	* lib/configure: When configuring for Linux, ignore the kernel version
	and always build all access methods.

	* Makefile (CFLAGS): Removed -Winline, it's not needed and triggers
	at many non-interesting places with gcc 3.4.

	* Whitespace cleanup of all source files.

	* The pci.ids file can be stored compressed if zlib is available.
	Added transparent decompression to lib/names.c, modified update-pciids.sh
	to keep the file compressed if applicable, updated Makefiles.
	Based on a patch by Matthew Wilcox, but all the bugs are mine.

	* Makefile, README: Allow installation to be done to a different directory
	from the one we will eventually be placed in by setting DESTDIR.
	Patch by Matthew Wilcox.

	* Added .gitignore files.

	* Makefile (clean): Clean *.orig, too.

	* Cleaned up usage of `char' and `byte'.

	* lib/header.h: PCI_CLASS_DOCKING_OTHER should be 0x0a80, not 0x0a01.

	* lib/header.h: Added PCI_CLASS_xxx constants for all classes currently
	defined in the pci.ids file.

2006-08-01  Martin Mares  <[e-mail]>

	* lib/i386-io-hurd.h: Fixed a silly typo.

2006-07-30  Martin Mares  <[e-mail]>

	* lib/Makefile: Added a missing rule for obsd-device.o.

	* lspci.c, lib/header.h: Added support for MSI per-vector masking.
	Contributed by Petr Vandrovec.

	* lspci.c, lib/header.h: Added support for the `bridge subsystem ID'
	capability. Contributed by Petr Vandrovec.

	* lspci.c (show_htype1): Fixed bug in printing of 64-bit prefetchable
	memory windows. Fix by Petr Vandrovec.

	* maint/release.pm: Exclude .git directory from releases.

	* lib/i386-ports.c, lib/i386-io-*: Report failures during port access
	initialization by a->warn() instead of calling printf() or perror()
	directly.

	* lib/i386-ports.c, lib/i386-io-*: Moved the logic which keeps track of
	the port access state to generic code.
