See http://www.gnu.org/ for details. 8 9 101. What's that? 11~~~~~~~~~~~~~~~ 12The PCI Utilities package contains a library for portable access to PCI bus 13configuration registers and several utilities based on this library. 14 15In runs on the following systems: 16 17 Linux (via /sys/bus/pci, /proc/bus/pci or i386 ports) 18 FreeBSD (via /dev/pci) 19 NetBSD (via libpci) 20 OpenBSD (via /dev/pci) 21 GNU/kFreeBSD (via /dev/pci) 22 Solaris/i386 (direct port access) 23 Aix (via /dev/pci and odmget) 24 GNU Hurd (direct port access) 25 Windows (direct port access) 26 CYGWIN (direct port access) 27 BeOS (via syscalls) 28 Haiku (via /dev/misc/poke) 29 Darwin (via IOKit) 30 31It should be very easy to add support for other systems as well (volunteers 32wanted; if you want to try that, I'll be very glad to see the patches and 33include them in the next version). 34 35The utilities include: (See manual pages for more details) 36 37 - lspci: displays detailed information about all PCI buses and devices. 38 39 - setpci: allows to read from and write to PCI device configuration 40 registers. For example, you can adjust the latency timers with it. 41 CAUTION: There is a couple of dangerous points and caveats, please read 42 the manual page first! 43 44 - update-pciids: download the current version of the pci.ids file. 45 46 472. Compiling and (un)installing 48~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 49Just run "make" to compile the package and then "make install" to install it. 50Please note that GNU make is needed on most platforms. 51 52If you want to change the default installation location, please override 53the PREFIX variable specified in the Makefile -- e.g., you can use 54"make PREFIX=/opt/pciutils install" to create a separate installation 55not interfering with the rest of your system. Setting the DESTDIR variable 56will allow you to install to a different directory from the one you intend 57to eventually run it from. This is useful for people who are packaging 58pciutils to install on other computers. 59 60There are several options which can be set in the Makefile or overridden 61when running make: 62 63 ZLIB=yes/no Enable support for compressed pci.ids (requires zlib). 64 If it is enabled, pciutils will use pci.ids.gz in preference to 65 pci.ids, even if the pci.ids file is newer. If the pci.ids.gz 66 file is missing, it will use pci.ids instead. If you do not 67 specify this option, the configure script will try to guess 68 automatically based on the presence of zlib. 69 70 DNS=yes/no Enable support for querying the central database of PCI IDs 71 using DNS. Requires libresolv (which is available on most 72 systems as a part of the standard libraries) and tries to 73 autodetect its presence if the option is not specified. 74 75 SHARED=yes/ Build libpci as a shared library. Requires GCC 4.0 or newer. 76 no/local The ABI of the shared library is intended to remain backward 77 compatible for a long time (we use symbol versioning to achieve 78 that, like GNU libc does). The value `local' includes the 79 right directory name in the binaries, so the utilities can be 80 run without installation. This is not recommended for any 81 production builds. 82 83"make install-lib" installs the library together with its header files 84for use by other programs. 85 86When you are bored of dumping PCI registers, just use "make uninstall". 87 88 893. Getting new IDs 90~~~~~~~~~~~~~~~~~~~ 91The database of PCI IDs (the pci.ids file) gets out of date much faster 92than I release new versions of this package, so it is maintained separately. 93 94It lives at http://pci-ids.ucw.cz/, where you can browse the database, 95download the most recent pci.ids file (e.g., by running the update-ids utility) 96and also submit new entries. 97 98Alternatively, you can use `lspci -q' to query the central database 99for new entries via network. 100 101The pci.ids file is also mirrored at http://pciids.sourceforge.net/ 102 103 1044. Getting new versions 105~~~~~~~~~~~~~~~~~~~~~~~ 106The current version of pciutils is available at: 107 108 http://mj.ucw.cz/sw/pciutils/ 109 110The tarball can be downloaded at the following places: 111 112 ftp://atrey.karlin.mff.cuni.cz/pub/linux/pci/ 113 ftp://ftp.kernel.org/pub/software/utils/pciutils/ (expect a couple of hours delay) 114 ftp://metalab.unc.edu/pub/Linux/hardware/ (expect a couple of days delay) 115 116There is also a public GIT tree at: 117 118 git://git.kernel.org/pub/scm/utils/pciutils/pciutils.git 119 120 1215. Using the library 122~~~~~~~~~~~~~~~~~~~~ 123So far, there is only a little documentation for the library except for the 124general introduction in the pcilib(7) man page. If you want to use the 125library in your programs, please follow the comments in lib/pci.h and in 126the example program example.c. 127 128 1296. Feedback 130~~~~~~~~~~~ 131If you have any bug reports or suggestions, send them to the author. 132 133If you have any new IDs, I'll be very glad to add them to the database. 134Just submit them at http://pci-ids.ucw.cz/. 135 136Announcements of new versions are sent to [email protected] 137(see http://vger.kernel.org/ for instructions). 138 139 Have fun 140 Martin 141
