	* lib/i386-io-hurd.h: Ask the kernel for I/O port access appropriately.
	Contributed by Thomas Schwinge and Samuel Thibault.

	* lib/i386-ports.c: Define _GNU_SOURCE, it's needed by the Hurd module.

	* lib/header.h: Whitespace cleanups.

	* lib/i386-io-windows.h: Fixed indentation and spelling.

	* README.Windows: Mention that WinIO.dll is needed and where to get it.

2006-06-27  Martin Mares  <[e-mail]>

	* lib/Makefile, Makefile: Added rules for building and cleaning the example.

	* lib/example.c: Show how to use PCI_FILL_CLASS and used another register
	for demonstrating the config space accesses. The example is still very
	incomplete, though.

	* lib/pci.h, lib/generic.c: Added PCI_FILL_CLASS.

	* lib/sysfs.c: Fetch device ID and class from sysfs, because they can
	be modified by kernel fixups.

	* lspci.c: Use PCI_FILL_CLASS. Thanks to Matthew Willcox for the patch.

2006-06-03  Martin Mares  <[e-mail]>

	* lspci.c: Introduced the -nn switch. Thanks to David N. Welton
	for the idea.

	* lib/names.c (pci_lookup_name): Introduced PCI_LOOKUP_MIXED and
	cleaned up the name selection code.

	* lib/names.c (pci_lookup_name): If PCI_LOOKUP_NO_NUMBERS is given,
	pci_access->numeric_ids is ignored.

	* lib/names.c (pci_lookup_name): When class is identified and
	subclass isn't, display class name and subclass number.

2006-05-31  Martin Mares  <[e-mail]>

	* setpci.c (main): Don't crash when an invalid width is specified.

	* lspci.c, setpci.c, common.c: die() now uses the right program
	name when printing an error message.

2006-05-19  Martin Mares  <[e-mail]>

	* README: Mention the public GIT tree.

	* README: Updated the list of ports.

2006-05-10  Martin Mares  <[e-mail]>

	* lib/configure, lib/fbsd-device.c: Added support for GNU/kFreeBSD.
	Thanks to Petr Salinger for the patch.

2006-05-05  Martin Mares  <[e-mail]>

	* Released as 2.2.3.

	* lspci.c (scan_device): The -D switch didn't work as intended
	in -m mode.

2006-05-05  Martin Mares  <[e-mail]>

	* Released as 2.2.2.

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

	* lib/obsd-device.c (and other files in lib/*): Added OpenBSD
	interface by Matthieu Herrb <[e-mail]>, based on
	the existing FreeBSD interface.

	* Moved pciutils to a GIT repository, which now contains merged
	history from both CVS and Arch. Good bye, TLA!

2006-03-21  Martin Mares  <[e-mail]>

	* lspci.c (show_slot_name): Avoid the previous changes in default
	display of domain name when in machine-readable mode. However, `-D'
	forces domain display even there.

	* lspci.man: Added a warning on -m being the only format, which is
	guaranteed to be stable between lspci versions.

2006-03-13  Martin Mares  <[e-mail]>

	* lspci.man: Documented the -D switch.

	* lspci.c (show_slot_name, scan_device): If there are multiple PCI
	domains or if the `-D' switch is used, show the domain number for
	all devices.

	* lspci.c (show_verbose): Report cache line size in bytes.

	* update-pciids.sh: Use curl if available. Patch by Matthew Wilcox.

2006-01-04  Martin Mares  <[e-mail]>

	* lspci.c (show_express_link): Fixed decoding of link status register.
	Thanks to Roland Dreier for his report.

2005-12-12  Martin Mares  <[e-mail]>

	* lib/nbsd-libpci.c: If libpci is used by an ordinary user, allow
	at least read-only access. Patch by Pavel Celeda <[e-mail]>.

	* Makefile: Corrected library path on NetBSD.

2005-11-26  Martin Mares  <[e-mail]>

	* Released as 2.2.1.

	* lspci.c (show_machine): Subsystem vendors were printed incorrectly
	in machine-readable modes. Thanks to Pavel Celeda for a bug report.

2005-10-11  Martin Mares  <[e-mail]>

	* lspci.c (new_bus): Fixed a memory leak. Thanks to Paul Sangree for reporting it.

2005-09-21  Martin Mares  <[e-mail]>

	* Released as 2.2.0.

	* pci.ids: Updated copyright header.

	* lib/sysfs.c (sysfs_get_resources): Removed warning about unsupported
	64-bit addresses, they are now always supported.

	* lspci.c (show_bases): Corrected printing of 64-bit addresses
	in bus-centric mode.

	* lib/configure: Enable 64-bit addresses on all Linux systems.

	* lib/types.h: Don't pad 64-bit addresses to 16 xigits, only to 8 if they
	are shorter.

2005-09-11  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test11.

	* lspci.c: Removed unnecessary trailing zeros in pci_lookup_name() calls.

2005-09-10  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test10.

	* pci.ids: Synchronized with the current database snapshot.

	* update-pciids.sh: Changed the default URL for downloading pci.ids
	to http://pciids.sourceforge.net/v2.2/pci.ids.

	* lib/pci.h (PCI_LIB_VERSION): Added version identifier.

	* lib/names.c: Rewritten the name database module almost from scratch.
	Everything is much cleaner and there are hopefully no more memory leaks;
	pci_lookup_name() now uses varargs in a backward compatible fashion.
	Introduced PCI_LOOKUP_NO_NUMBERS.

	The new code supports subsystem entries not tied to a specific device.
	I had to extend the format of pci.ids in order to support it, so I have
	extended the idea of the "C" (class) blocks and introduced "S" blocks
	for subsystems. To avoid doing more incompatible changes in the future,
	the parser skips unknown single-letter blocks without reporting errors.

2005-08-23  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test9.

	* Makefile (OPT): Removed -fomit-frame-pointer, it's default in recent
	gcc versions when optimizing anyway.

	* Made the path to pci.ids customizable and independent on the SHAREDIR.
	Just override IDSDIR in the top-level Makefile.

	* pci.ids: Synchronized with the current database snapshot.

	* lspci.man, setpci.man: Improved the man pages. Documented all access
	methods and which operations are privileged.

	* lspci.c: Another rewrite of config register caching, now also including
	lots of internal checks. It should be now perfectly able to cope with
	portions of the configuration space being inaccessible, for example
	due to insufficient access rights.

	* lspci.c (show_pcix_nobridge, show_pcix_bridge): Cleaned up dumping of PCI-X
	capabilities. Includes partial support for PCI-X 2.0 (probably incomplete
	as I haven't seen the spec).

	* lspci.c: Quell warnings about unused parameters.

	* lspci.c: Removed C++ comments.

	* lib/header.h: Merged definitions of extended capabilities and some new
	PCI-X capability bits from linux-2.6.11/include/pci.h.

	* lspci.c (show_caps): Try to scan extended capabilities only if the
	device has either PCI-X or PCI Express capability in its normal capability
	list.

	* lib/dump.c (dump_init): Reading of dumps works again. The dump reader
	now also remembers how much data it has read and refuses attempts to
	access more than that.

	* setpci.man, lspci.c, README: prefer spelling "buses" over "busses".

	* lspci.c: If alloca() is not available, use xmalloc(), not malloc().

	* lib/configure: Added x86_64 on Linux.

2005-08-22  Martin Mares  <[e-mail]>

	* lib/filter.c (pci_filter_parse_slot): Fixed parsing of domain filters.
	Thanks to Matthew Wilcox for bug report.

	* lspci.c: Corrected spelling of "Hz" (it was "hz" at several places).
	Thanks to Krzysztof Oledzki for pointing that out.

2004-08-19  Martin Mares  <[e-mail]>

	* pciutils.spec (%attr): Setting attributes for /sbin/* is an anachronism,
	because pciutils by default install to /usr/sbin. Update.

2004-08-13  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test8.

	* lib/types.h, lib/pci.h, lib/sysdep.h: `byte' and `word' are
	no longer exported to the outside world.

	* README.Windows: Updated.

	* maint/release: Substitute version number in win32/config.h.

	* win32/config.h: Added.

	* lib/sysdep.h (bzero, strcasecmp): are macros on Windows.

	* compat/getopt.[ch]: Added copies of getopt.[ch] from the GNU
	C library for use on systems where the default libraries lack
	proper getopt. Currently used by the Windows port.

	* lib/sysdep.h, lib/types.h: Updates of the Windows port from
	Alexander Stock.

	* lib/types.h: If PCI_HAVE_Uxx_TYPES is defined, libpci doesn't define
	its own u8, u16, u32, byte and word types and uses what the user
	has supplied instead. With this change, all namespace clashes should
	be gone.

	* Makefile, lib/Makefile: Updated dependencies.

	* pciutils.h: Include lib/sysdep.h and move NONRET et al. there.

	* lib/sysdep.h: No need to include <sys/types.h> on FreeBSD, because
	it is included unconditionally in lib/types.h.

	* Moved system-dependent stuff from lib/internal.h to lib/sysdep.h,
	which is also used by the utilities. Also moved type declarations
	from lib/pci.h to lib/types.h.

	* All files: Prepend a "PCI_" prefix in front of all configuration
	defines to avoid namespace clashes. CAVEAT: If there is any libpci
	application using the (undocumented) defines, it has to be updated.

	* lib/Makefile: Killed HAVE_OWN_HEADER_H, since we stopped sharing
	headers with the kernel a couple of years ago.

	* lib/sysfs.c (sysfs_get_resources): We have 7 resources, not 6.

	* lspci.c (show_rom): Use the same logic for printing disabled
	or unassigned ROM's as we do in show_bases() for the other BAR's.

	* lib/generic.c (pci_generic_fill_info): Better reaction to
	invalid 64-bit addresses. Also d->hdrtype should not include
	bit 7, which caused mysterious errors on multi-function devices.

	* lib/generic.c (pci_generic_fill_info): Fill in base addresses
	even if the regions are known to be disabled. It is the client's
	job to interpret them. (And it is not a trivial job if you want
	to do it correctly, since you need to check I/O and memory enables
	on all upstream bridges, too.) However, it could be interesting to
	introduce functions for interpreting the addresses and even for
	mapping the regions and doing I/O on them.

2004-07-30  Martin Mares  <[e-mail]>

	* lspci.c: HyperTransport improvements from Maciej.

2004-07-11  Martin Mares  <[e-mail]>

	* lib/sysfs.c (sysfs_get_resources): Arguments now correspond
	to the format string. [Patch by Bill Nottingham]

2004-07-05  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test7.

	* lspci.c (config_fetch): Wanted to merge Matthew's bug fix, but
	ended up with rewriting the fetching mechanism to be fully dynamic,
	but avoid reading config space registers not explicitly requested.

2004-06-29  Matthew Wilcox <[e-mail]>

	* lspci.c: More work on PCI Express dumping.

	* lib/header.h: Updated PCI Express capability definitions.

	* lib/proc.c (proc_read): Removed bogus warning.

	* common.c (xrealloc): Introduced.

	* lspci.man: Added -xxxx.

2004-06-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test6.

	* lspci.c (show_msix), lib/header.h: Added dumping of MSI-X cap.
	Patch by Roland Dreier <[e-mail]>, cleaned up by me.

	* lspci.c (show_pcix_nobridge, show_pcix_bridge): Handle config_fetch()
	failures.

	* lib/header.h: Added PCI Express extended capabilities. Again by Matthew.

	* lspci.c (show_express): Added dumping of PCI Express cap.
	Patch by Matthew Wilcox.

	* lib/header.h: Added a list of PCI 3.0 capabilities and also details
	on PCI Express caps. Patch by Matthew Wilcox <[e-mail]>.

	* lspci.c (check_root): Gone. No explicit checks for root are needed,
	report correct errors reported by the libpci instead.

	* lspci.c: Added dumping of the extended config space on "-xxxx".
	Better caching of config registers.

	* setpci.c (main): Allow access to whole 4096 bytes of the config space.

	* lib/sysfs.c, lib/proc.c: Don't print error messages on short reads,
	just return the appropriate error code.

	* lib: Added support for extended (4096-byte) configuration space,
	currently implemented only in Linux proc and sysfs access methods
	and of course in the dump reader.

2004-05-29  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test5.

	* lib/pci.h: Windows don't have the standard u_int* types.

	* lib/internal.h: <sys/param.h> required on Windows for endianity
	macros.

	* lib/i386-ports.c: Connected i386-io-windows.h.

	* lspci.c (check_root): geteuid() is not available on Windows.

	* lib/i386-io-windows.h: Added Windows port contributed by Alexander
	Stock <[e-mail]>.

	* lib/configure: Hopefully fixed SunOS port broken by various
	changes to the configure script.

	* Makefile, lib/configure: Cross-compilation support, patch by Maciej.

2004-05-28  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test4.

	* lspci.c (show_verbose): Header type 1 is probably legal for all
	types of bridges, not only for PCI-to-PCI bridges.

	* lspci.c (format_agp_rate): Write "x16", not "x@".
	(show_agp): rate[] could overflow.
	Bugs reported by Jakub Bogusz <[e-mail]>.

	* lspci.c (show_ht_*): Show HyperTransport capability with all its
	details. Once again code by Maciej simplified (i.e., possibly broken)
	by me.

	* lib/header.h: Added declarations of HyperTransport capability.
	Again thanks to Maciej.

	* lspci.c: Decode all bits of the secondary status word in type 1 headers.
	Thanks to Maciej W. Rozycki <[e-mail]> for the patch.

2003-12-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test3.

	* lspci.man, setpci.man: Document domains and correct spelling.

	* lib/dump.c (dump_init): Added ability to read domain numbers.

	* lspci.c: Devices in domains different from 0 have their slot number
	printed as "<domain>:<bus>:<slot>.<func>". Tree view supports domains
	as well.

	* lib/filter.c: Slot filters understand domains.

	* lib/generic.c: Mention the domain in slot numbers in all error messages.

	* lib/internal.h: The #ifdef for Linux <asm/byteorder.h> was wrong.

	* lib/access.c (pci_get_dev): Added support for domains.

	* lib/sysfs.c (sysfs_scan): Read vendor and device ID from the config
	registers (or to be precise, leave it for the generic parts of the pcilib
	to do so) instead of reading them from the sysfs. It's faster this way.

	* lspci.c (show_pcix): Don't touch pci_dev->hdrtype, it's an internal
	variable. Better read it from the config registers (it's cached anyway).

	* lib/sysfs.c (sysfs_scan), lib/proc.c (proc_scan): Don't read the hdrtype.
	  lib/generic.c (pci_generic_fill_info): If hdrtype is -1 (unset), read it.
	  Saves lots of unnecessary file accesses.

	* lib/pci.h (PCIADDR_PORT_FMT): Use %llx instead of %Lx, because the latter
	is not supported by all C libraries.

	* Makefile: Always enter the lib directory (remember that we don't have
	full dependecies for the library in the top-level Makefile; hmmm, another
	thing to rewrite some day).

	* lib/sysfs.c: Added Linux sysfs access method based on the patch
	written by Matthew Wilcox <[e-mail]>.

	* lib/proc.c: Renamed the access method name from "/proc/bus/pci" to "Linux-proc".

	* lib/pread.h: The hacks to support pread on various versions
	of Linux libc moved there.

	* lib/proc.c (proc_setup): The return value of snprintf() varies
	between glibc versions, so we need to check both for a negative
	values and for too large values.

	* Removed last few references to the "Linux PCI Utilities", the
	package is pretty cross-platform now :)

2003-12-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test2.

	* README, pciutils.lsm, pciutils.spec: Use @VERSION@ to make the
	release scripts insert the current version. "make release" is gone.

	* maint/release, maint/release.pm: Added a new system of scripts for
	making releases including inter-version diffs etc.
