  10 1. What's that?
  11 ~~~~~~~~~~~~~~~
  12 The PCI Utilities package contains a library for portable access to PCI bus
  13 configuration registers and several utilities based on this library.
  14
  15 In 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
  27 It should be very easy to add support for other systems as well (volunteers
  28 wanted; if you want to try that, I'll be very glad to see the patches and
  29 include them in the next version).
  30
  31 The utilities include:  (See manual pages for more details)
  32
  33   - lspci: displays detailed information about all PCI buses and devices.
  34
  35   - setpci: allows to read from and write to PCI device configuration
  36     registers. For example, you can adjust the latency timers with it.
  37     CAUTION: There is a couple of dangerous points and caveats, please read
  38     the manual page first!
  39
  40   - update-pciids: download the current version of the pci.ids file.
  41

  43 2. Compiling and (un)installing
  44 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  45 Just run "make" to compile the package and then "make install" to install it.
  46
  47 If you want to change the default installation location, please override
  48 the PREFIX variable specified in the Makefile -- e.g., you can use
  49 "make PREFIX=/opt/pciutils install" to create a separate installation
  50 not interfering with the rest of your system.  Setting the DESTDIR variable
  51 will allow you to install to a different directory from the one you intend
  52 to eventually run it from.  This is useful for people who are packaging
  53 pciutils to install on other computers.
  54
  55 The configure script will automatically enable support for a compressed
  56 pci.ids if you have zlib installed.  You can override its guess by using
  57 "make ZLIB=no" or "make ZLIB=yes".  If compressed support is enabled,
  58 pciutils will use pci.ids.gz in preference to pci.ids, even if the
  59 pci.ids file is newer.  If the pci.ids.gz file is missing, it will use
  60 pci.ids instead.
  61
  62 When you are bored of dumping PCI registers, just use "make uninstall".
  63
  64
  65 3. Getting new ID's
  66 ~~~~~~~~~~~~~~~~~~~
  67 The database of PCI ID's (the pci.ids file) gets out of date much faster
  68 than I release new versions of this package.
  69
  70 If you are missing names for any of your devices or you just want to stay
  71 on the bleeding edge, download the most recent pci.ids file from
  72 http://pciids.sf.net/ (e.g., by running the update-ids utility).
  73
  74 If your devices still appear as unknown, please send us their ID's and
  75 names, the detailed instructions for submissions are listed on the
  76 sf.net web page.
  77
  78
  79 4. Getting new versions
  80 ~~~~~~~~~~~~~~~~~~~~~~~
  81 New versions of pciutils are available at the following places:
  82
  83         ftp://atrey.karlin.mff.cuni.cz/pub/linux/pci/
  84         ftp://ftp.kernel.org/pub/software/utils/pciutils/ (expect a couple of hours delay)
  85         ftp://metalab.unc.edu/pub/Linux/hardware/ (expect a couple of days delay)
  86
  87 There is also a public GIT tree at:
  88
  89         git://git.kernel.org/pub/scm/utils/pciutils/pciutils.git
  90
  91
  92 5. Using the library
  93 ~~~~~~~~~~~~~~~~~~~~
  94 There is still no documentation for the library, if you want to use it
  95 in your programs, please follow the comments in lib/pci.h and in the
  96 example program lib/example.c.
  97
  98
  99 6. Feedback
 100 ~~~~~~~~~~~
 101 If you have any bug reports or suggestions, send them to the author.
 102
 103 If you have any new ID's, I'll be very glad to add them to the database, but
 104 please take a look at http://pciids.sf.net/ first and follow the instructions.
 105
 106 If you want, subscribe to linux-pci@atrey.karlin.mff.cuni.cz (send
 107 "subscribe linux-pci" to majordomo@atrey.karlin.mff.cuni.cz).
 108 Release notes about new versions will be send to the list and problems with
 109 the Linux PCI support will be probably discussed there, too.

 112 7. Miscellanea
 113 ~~~~~~~~~~~~~~
 114 You also might want to look at the pciutils web page containing release
 115 notes and other news: http://mj.ucw.cz/pciutils.shtml .
 116
 117 There also exists a utility called PowerTweak which is able to fine tune
 118 parameters of many chipsets much better than the Bridge Optimization code
 119 in Linux kernel (already removed in 2.3.x). See http://powertweak.sf.net/
 120 for more information.
