Copyright (c) 1997--2020 Martin Mares <mj@ucw.cz> All files in this package can be freely distributed and used according to the terms of the GNU General Public License, either version 2 or (at your opinion) any newer version. See https://www.gnu.org/ for details. 1. What's that? ~~~~~~~~~~~~~~~ The PCI Utilities package contains a library for portable access to PCI bus configuration registers and several utilities based on this library. In runs on the following systems: Linux (via /sys/bus/pci, /proc/bus/pci or i386 ports) FreeBSD (via /dev/pci) NetBSD (via libpci) OpenBSD (via /dev/pci) GNU/kFreeBSD (via /dev/pci) Solaris/i386 (direct port access) Aix (via /dev/pci and odmget) GNU Hurd (direct port access) Windows (direct port access, see README.Windows for caveats) CYGWIN (direct port access) BeOS (via syscalls) Haiku (via /dev/misc/poke) Darwin (via IOKit) DOS/DJGPP (via i386 ports) SylixOS (via /proc/pci) It should be very easy to add support for other systems as well (volunteers wanted; if you want to try that, I'll be very glad to see the patches and include them in the next version). The utilities include: (See manual pages for more details) - lspci: displays detailed information about all PCI buses and devices. - setpci: allows to read from and write to PCI device configuration registers. For example, you can adjust the latency timers with it. CAUTION: There is a couple of dangerous points and caveats, please read the manual page first! - update-pciids: download the current version of the pci.ids file. 2. Compiling and (un)installing ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Just run "make" to compile the package and then "make install" to install it. Please note that GNU make is needed on most platforms. If you want to change the default installation location, please override the PREFIX variable specified in the Makefile -- e.g., you can use "make PREFIX=/opt/pciutils install" to create a separate installation not interfering with the rest of your system. Setting the DESTDIR variable will allow you to install to a different directory from the one you intend to eventually run it from. This is useful for people who are packaging pciutils to install on other computers. There are several options which can be set in the Makefile or overridden when running make: ZLIB=yes/no Enable support for compressed pci.ids (requires zlib). If it is enabled, pciutils will use pci.ids.gz in preference to pci.ids, even if the pci.ids file is newer. If the pci.ids.gz file is missing, it will use pci.ids instead. If you do not specify this option, the configure script will try to guess automatically based on the presence of zlib. DNS=yes/no Enable support for querying the central database of PCI IDs using DNS. Requires libresolv (which is available on most systems as a part of the standard libraries) and tries to autodetect its presence if the option is not specified. SHARED=yes/ Build libpci as a shared library. Requires GCC 4.0 or newer. no/local The ABI of the shared library is intended to remain backward compatible for a long time (we use symbol versioning to achieve that, like GNU libc does). The value `local' includes the right directory name in the binaries, so the utilities can be run without installation. This is not recommended for any production builds. "make install-lib" installs the library together with its header files for use by other programs. When you are bored of dumping PCI registers, just use "make uninstall". 3. Getting new IDs ~~~~~~~~~~~~~~~~~~~ The database of PCI IDs (the pci.ids file) gets out of date much faster than I release new versions of this package, so it is maintained separately. It lives at https://pci-ids.ucw.cz/, where you can browse the database, download the most recent pci.ids file (e.g., by running the update-ids utility) and also submit new entries. Alternatively, you can use `lspci -q' to query the central database for new entries via network. The pci.ids file is also mirrored at https://github.com/pciutils/pciids. On Linux systems with a recent enough version of libudev, UDEV's HWDB database is consulted when pci.ids lacks the device. 4. Getting new versions ~~~~~~~~~~~~~~~~~~~~~~~ The current version of pciutils is available at: https://mj.ucw.cz/sw/pciutils/ The tarball can be downloaded at the following places: https://mj.ucw.cz/download/linux/pci/ ftp://ftp.ucw.cz/pub/mj/linux/pci/ https://www.kernel.org/pub/software/utils/pciutils/ (expect a couple of hours delay) There is also a public GIT tree at: https://git.kernel.org/pub/scm/utils/pciutils/pciutils.git https://github.com/pciutils/pciutils 5. Using the library ~~~~~~~~~~~~~~~~~~~~ So far, there is only a little documentation for the library except for the general introduction in the pcilib(7) man page. If you want to use the library in your programs, please follow the comments in lib/pci.h and in the example program example.c. 6. Feedback ~~~~~~~~~~~ If you have any bug reports or suggestions, send them to the author. If you have any new IDs, I'll be very glad to add them to the database. Just submit them at https://pci-ids.ucw.cz/. Announcements of new versions are sent to linux-pci@vger.kernel.org (see http://vger.kernel.org/ for instructions). Have fun Martin PK ut!\]���&! &! ChangeLognu �[��� 2020-05-31 Martin Mares <mj@ucw.cz> * Released as 3.7.0. * Added or improved the following capabilities: Designated Vendor-Specific, Compute eXpress Link, Resizable BARs, VF Resizable BARs, Link Capabilities 2, Link Status 2. * On Linux, lspci can show IOMMU groups. * setpci can be asked to skip bus scan and operate on a device completely specified by its domain/bus/dev/func address. 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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. All flags are now printed after the address (previously, "[virtual]" and "[enhanced]" were before it for no good reason). * Added pci_find_cap_nr() to the library, which handles capabilities which occur multiple times in a single device. * Minor improvements in printing of PCIe capabilities. * We now decode the Multicast and Secondary PCI Express extended capabilities. * The list of capability names available to setpci was updated. * Minor bugs were fixed in FreeBSD and Solaris ports. * We now prefer HTTPS URLs in all documentation * The pci.ids file has a man page. * As usually, updated pci.ids to the current snapshot of the database. 2018-08-12 Martin Mares <mj@ucw.cz> * Released as 3.6.2. * Added "-P" and "-PP" switches to lspci, which display the path through bridges to each device. * Fixed a couple of bugs in computation of bus topology. It was previously used only for the tree display, but we re-use it for computing the paths. * As usually, updated pci.ids to the current snapshot of the database. 2018-07-12 Martin Mares <mj@ucw.cz> * Released as 3.6.1. * Fixed compilation issues on Linux systems with MUSL libc. 2018-06-30 Martin Mares <mj@ucw.cz> * Released as 3.6.0. * BARs reported by the OS, but not set on the device itself are reliably marked with "[virtual]". * Library: Introduced a generic mechanism of string properties. This avoids lots of special cases and makes ABI compatibility easier. * On Linux systems with OpenFirmware, report corresponding device tree nodes as device properties. * VPD decoder knows several non-standard extensions. * When PCIe link speed is less than the maximum supported by the device, it is explicitly marked as "downgraded". * Several new capabilities are not decoded yet, but at least their names are printed. * The Null capability is easily decoded. * Formatting of several capabilities was cleaned up. * The VGA16 bit in the bridge control register is now supported. * Added a port to SylixOS. Thanks to YuJian Gong for contribution. * Added a port to DOS/DJGPP. Thanks to Rudolf Marek for contribution. * The order in which back-ends are probed was decoupled from the internal back-end IDs. This helps, because new back-ends must have their ID allocated at the end to keep the ABI, but they might need to be probed earlier. * The fbsd-device back-end should work again. * Fixed a couple of bugs. Most notably, DeviceName was not printed. * As usually, updated pci.ids to the current snapshot of the database. 2017-11-17 Martin Mares <mj@ucw.cz> * Released as 3.5.6. * Improvements of the FreeBSD back-end: read-only access for non-root, support DragonFly BSD, support extended config space. * MN VPD keyword is decoded correctly. * As usually, updated pci.ids to the current snapshot of the database. 2017-07-05 Martin Mares <mj@ucw.cz> * Released as 3.5.5. * Better decoding of AER capability. * "Slot Implemented" flag is decoded for PCI/PCI-X to PCIe bridges. * Minor fixes of decoding other capabilities. * As usually, updated pci.ids to the current snapshot of the database. 2017-02-25 Martin Mares <mj@ucw.cz> * Released as 3.5.4. * Previous version broke compilation on systems, for which lib/types.h did not provide a 64-bit integer type. It is provided everywhere now. 2017-02-15 Martin Mares <mj@ucw.cz> * Released as 3.5.3. * When lspci looks for Linux kernel modules, it uses the default path to module directory provided by libkmod. Previously, it tried to construct the path explicitly, which need not work on all systems. * Improved formatting of memory and I/O ranges behind a bridge. * PCIe link capabilities now display GEN4 speed (16GT/s). * PCIe device capabilities now show bits related to atomic operations. Thanks to Satanand Burla for a patch. * As usually, updated pci.ids to the current snapshot of the database. 2016-10-03 Martin Mares <mj@ucw.cz> * Released as 3.5.2. * The L1 power management capability is now decoded more thoroughly. Thanks to Rajat Jain for the patch. * The table of configuration registers used by setpci had a bug in the definition of SUBSYSTEM_VENDOR_ID. 2016-05-22 Martin Mares <mj@ucw.cz> * Released as 3.5.1. * Fixed symbol versioning of pci_init(). 2016-05-19 Martin Mares <mj@ucw.cz> * Released as 3.5.0. * New capabilities decoded: Downstream Port Containment, Precision Time Measurement. Thanks to Keith Busch and Jonathan Yong. * Domain numbers extended to 31 bits. This will be used by the Linux kernel on some machines in near future. * Enhanced allocation regions are now decoded on Linux. * The NetBSD back-end supports PCIe extended configuration space. * Updated pci.ids to the current snapshot of the database. 2016-01-03 Martin Mares <mj@ucw.cz> * Released as 3.4.1. * New capabilities decoded: Process Address Space, Page Request Interface, Enhanced Allocation. Thanks to David Daney and David Woodhouse. * DevCap SlotPowerLimit is now decoded for all components with upstream ports. * Database mirror at SourceForge moved to GitHub. * Updated pci.ids to the current snapshot of the database. 2015-09-14 Martin Mares <mj@ucw.cz> * Released as 3.4.0. * On Linux, we report NUMA nodes of devices. * The sysfs back-end does not die on read errors of optional attributes. Instead, a warning is produced. * Fixed several minor bugs. * Updated pci.ids to the current snapshot of the database. 2015-04-09 Martin Mares <mj@ucw.cz> * Released as 3.3.1. * Removed hacks for backward compatibility with Linux libc5, which were breaking newer non-glibc Linux systems. Thanks to Felix Janda. * Display VirtIO vendor-specific capability. Patch by Gerd Hoffmann. * Fixed memory leak in name cache. * Updated pci.ids to the current snapshot of the database. 2014-11-10 Martin Mares <mj@ucw.cz> * Released as 3.3.0. (celebrating a one-year anniversary of the previous version :)) * Device names exported by BIOS are displayed on Linux. * On Linux systems, HWDB is used to look up device names when our ID database gives no match. (More precisely, HWDB is consulted after local pci.ids, but before using network to query online pci.ids.) Thanks to Tom Gundersen for the initial patch. * Added experimental back-end for OS X / Darwin. Thanks to Richard Yao for providing it. * Filters now support matching by device class. Original patch by Matthew Wilcox, wrappers for ABI compatibility by me. * Interrupt Pin and Interrupt Line registers are displayed for bridge devices, too. * Several portability bugs have been fixed. * Several typos have been fixed. Also, use of questionable constructs in man pages has been reduced. * PCIe link capabilities now include the ASPMOptComp bit. * The "CRS Software Visibility" bit is now decoded properly. * Updated pci.ids to the current snapshot of the database. 2013-11-10 Martin Mares <mj@ucw.cz> * Released as 3.2.1. * CardBus bridge capabilities are displayed. * PCIe L1 PM substates are decoded. * Various bugs were fixed in decoding of PCIe capabilities. * The sysfs back-end does not spit out unnecessary warnings when empty slots report only a partial device address. This actually happens on IBM pSeries. * Updated pci.ids to the today's snapshot of the database. 2013-04-19 Martin Mares <mj@ucw.cz> * Released as 3.2.0. * On newer Linux systems, we use libkmod to look up kernel modules (modules.pcimap no longer exists). To facilitate this, libpci is able to look up module aliases in sysfs. * Various minor bug fixes. * Updated pci.ids to the today's snapshot of the database. 2012-06-25 Martin Mares <mj@ucw.cz> * Released as 3.1.10. * Decoding of LTR/OBFF in PCIe capabilities. * Various minor bug fixes. * Updated pci.ids to the today's snapshot of the database. 2012-01-14 Martin Mares <mj@ucw.cz> * Released as 3.1.9. * Updated README. * Wherever we mention the PCI ID database, we now refer to http://pci-ids.ucw.cz/ and the sf.net site is mentioned only as a mirror. This includes update-pciids. * Decode PCIe Gen 3 speeds and link status fields. * Various minor bug fixes. * Updated pci.ids to the today's snapshot of the database. 2011-10-02 Martin Mares <mj@ucw.cz> * Released as 3.1.8. * More capabilities: Transaction Processing Hints, Latency Tolerance Reporting. Thanks to Jesse Barnes. * Added BeOS and Haiku ports. Contributed by Francois Revol. * pciutils.pc now uses Libs.private properly. * When we format a name and it does not fit in the buffer, we truncate it instead of returning "buffer too small" instead. This works on all platforms with sane (i.e., C99-compatible) snprintf(). * Various minor bug fixes. * Updated pci.ids to the today's snapshot of the database. 2010-01-31 Martin Mares <mj@ucw.cz> * Released as 3.1.7. * Minor improvements and bug fixes in decoding of the Virtual Channel capability. 2010-01-24 Martin Mares <mj@ucw.cz> * Released as 3.1.6. * More capabilities decoded: Virtual Channel (except arbitration tables), Root Complex Link, Vendor-Specific (header only), SATA HBA. * All extended capabilities have their version displayed (-vv or more). 2010-01-19 Martin Mares <mj@ucw.cz> * Released as 3.1.5. * Updated pci.ids to the today's snapshot of the database. * When scanning extended capabilities, properly mask the lowest 2 bits, which are currently reserved. This avoids unaligned access errors on broken hardware (see tests/broken-ecaps). * Large bar sizes are displayed in human-readable format (with units). Thanks to Matthew Wilcox. * Physical slot information is displayed correctly for multi-function cards. Fixed by Matthew Wilcox. * Fixed a couple of typos everywhere. * Library: Fixed bugs in freeing of capabilities. * Windows back-end compiles again. 2009-08-14 Martin Mares <mj@ucw.cz> * Released as 3.1.4. (sorry that I have missed 22/7 and released it later :-)) * Updated pci.ids to the today's snapshot of the database. * Fixed memory and file descriptor leak in the dump back-end. * The SR-IOV capability decoder now prints the VF BAR's. Patch by Chris Wright, cleaned up by me. * On request of certain company's lawyers, we now include a copy of the GPL with our package. It seems that the pciutils are getting mature if the most important bug of the month was this one ;-) 2009-07-04 Martin Mares <mj@ucw.cz> * Released as 3.1.3. * Updated pci.ids to the current snapshot of the database. * The VPD parser now reports unknown and vendor-defined items properly. It also stops on any item in unknown format, avoiding long output on bogus VPD data. Thanks to Ben Hutchings and Matthew Wilcox. * The MSI-X table size now matches the spec. Thanks to Michael S. Tsirkin. * The Power Management capability now includes the soft reset bit. Thanks to Yu Zhao. * Decoding of the Advanced Features capability has been added. Thanks to Yu Zhao. * The whole package compiles on GNU/kFreeBSD again. The following patches have been contributed by Matthew Wilcox: * The procfs back-end is able to cope with /proc/bus/pci containing names with domains, which occur on sparc64 and possibly other architectures due to a kernel bug. * The sysfs back-end no longer complains when a slot address is missing, which happens with old versions of Linux fakephp. * The Device Serial Number capability is printed in the right byte order. * The MSI and MSI-X capabilities are printed in a prettier way. * The tree output mode (`lspci -t') shows domain numbers only at the root, which makes the output more compact. * Updated documentation on the bus mapping mode (`lspci -M'). 2009-02-01 Martin Mares <mj@ucw.cz> * Released as 3.1.2. * Fixed another silly bug in the command-line parser of setpci. 2009-01-30 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 linux-pci@vger.kernel.org. * 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 <mj@ucw.cz> * Released as 3.0.0. * Updated API and ABI version. 2008-02-20 Martin Mares <mj@ucw.cz> * Released as 2.99.1-alpha2. * Changed the default domain for the DNS resolver. 2008-02-18 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * lib/dump.c: Squashed compiler warnings about code with no effect (there really were surplus *'s). 2007-11-06 Martin Mares <mj@ucw.cz> * 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 <anicka@anicka.net> for help. 2007-10-19 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * lib/[fno]bsd-*: Removed extraneous braces. 2007-10-12 Martin Mares <mj@ucw.cz> * Capability loop detection introduced 2.2.7 did not work properly with extended capabilities. Fixed. 2007-10-05 Martin Mares <mj@ucw.cz> * 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 <hasso@estpak.ee> * 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 <mj@ucw.cz> * Resurrected the Windows port, including cross-compilation by MinGW. Patch by Samuel Bronson <naesten@gmail.com>. 2007-08-31 Martin Mares <mj@ucw.cz> * Makefile, lib/Makefile: `ar' and `ranlib' can be overriden to allow cross-compilation. 2007-08-27 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <tschwinge@gnu.org> * lib/i386-io-hurd.h: Rewritten for new Hurd kernels. 2007-05-04 Martin Mares <mj@ucw.cz> * Released as 2.2.5. * pci.ids: Updated to the current snapshot of the database. 2007-02-14 Martin Mares <mj@ucw.cz> * lspci.c (show_express): Added PCI/PCI-X to PCI-Express Bridge type. Patch by Mark Glines. 2007-02-09 Martin Mares <mj@ucw.cz> * pci.ids: Updated to the current snapshot of the database. 2007-02-06 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * lspci.c: alloca() needs <alloca.h>. 2006-09-17 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * lib/i386-io-hurd.h: Fixed a silly typo. 2006-07-30 Martin Mares <mj@ucw.cz> * 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. * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * README: Mention the public GIT tree. * README: Updated the list of ports. 2006-05-10 Martin Mares <mj@ucw.cz> * lib/configure, lib/fbsd-device.c: Added support for GNU/kFreeBSD. Thanks to Petr Salinger for the patch. 2006-05-05 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <matthieu.herrb@laas.fr>, 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * lspci.c (show_express_link): Fixed decoding of link status register. Thanks to Roland Dreier for his report. 2005-12-12 Martin Mares <mj@ucw.cz> * lib/nbsd-libpci.c: If libpci is used by an ordinary user, allow at least read-only access. Patch by Pavel Celeda <celeda@liberouter.org>. * Makefile: Corrected library path on NetBSD. 2005-11-26 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * lspci.c (new_bus): Fixed a memory leak. Thanks to Paul Sangree for reporting it. 2005-09-21 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * Released as 2.1.99-test11. * lspci.c: Removed unnecessary trailing zeros in pci_lookup_name() calls. 2005-09-10 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * 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 <mj@ucw.cz> * pciutils.spec (%attr): Setting attributes for /sbin/* is an anachronism, because pciutils by default install to /usr/sbin. Update. 2004-08-13 Martin Mares <mj@ucw.cz> * 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 <mj@ucw.cz> * lspci.c: HyperTransport improvements from Maciej. 2004-07-11 Martin Ma
