+libdrm - userspace library for drm
+
+This is libdrm, a userspace library for accessing the DRM, direct
+rendering manager, on Linux, BSD and other operating systes that
+support the ioctl interface. The library provides wrapper functions
+for the ioctls to avoid exposing the kernel interface directly, and
+for chipsets with drm memory manager, support for tracking relocations
+and buffers. libdrm is a low-level library, typically used by
+graphics drivers such as the Mesa DRI drivers, the X drivers, libva
+and similar projects. New functionality in the kernel DRM drivers
+typically requires a new libdrm, but a new libdrm will always work
+with an older kernel.
+
+
+Compiling
+---------
+
+libdrm is a standard autotools packages and follows the normal
+configure, build and install steps. The first step is to configure
+the package, which is done by running the configure shell script:
+
+ ./configure
+
+By default, libdrm will install into the /usr/local/ prefix. If you
+want to install this DRM to replace your system copy, pass
+--prefix=/usr and --exec-prefix=/ to configure. If you are building
+libdrm from a git checkout, you first need to run the autogen.sh
+script. You can pass any options to autogen.sh that you would other
+wise pass to configure, or you can just re-run configure with the
+options you need once autogen.sh finishes.
+
+Next step is to build libdrm:
+
+ make
+
+and once make finishes successfully, install the package using
+
+ make install
+
+If you are install into a system location, you will need to be root to
+perform the install step.

+The release criteria for libdrm is essentially "if you need a release,
+make one". There is no designated release engineer or maintainer.
+Anybody is free to make a release if there's a certain feature or bug
+fix they need in a released version of libdrm.
+
+When new ioctl definitions are merged into drm-next, we will add
+support to libdrm, at which point we typically create a new release.
+However, this is up to whoever is driving the feature in question.
+
+Follow these steps to release a new version of libdrm:
+
+ 1) Ensure that there are no local, uncommitted/unpushed
+ modifications. You're probably in a good state if both "git diff
+ HEAD" and "git log master..origin/master" give no output.
+
+ 3) Bump the version number in configure.ac. We seem to have settled
+ for 2.4.x as the versioning scheme for libdrm, so just bump the
+ micro version.
+
+ 4) Run autoconf and then re-run ./configure so the build system
+ picks up the new version number.
+
+ 5) Verify that the code passes "make distcheck". libdrm is tricky
+ to distcheck since the test suite will need to become drm master.
+ This means that you need to run it outside X, that is, in text
+ mode (KMS or no KMS doesn't matter).
+
+ Running "make distcheck" should result in no warnings or errors
+ and end with a message of the form:
+
+ =============================================
+ libdrm-X.Y.Z archives ready for distribution:
+ libdrm-X.Y.Z.tar.gz
+ libdrm-X.Y.Z.tar.bz2
+ =============================================
+
+ Make sure that the version number reported by distcheck and in
+ the tarball names matches the number you bumped to in configure.ac.
+
+ 6) Commit the configure.ac change and make an annotated tag for that
+ commit with the version number of the release as the name and a
+ message of "libdrm X.Y.Z". For example, for the 2.4.16 release
+ the command is:
+
+ git tag -a 2.4.16 -m "libdrm 2.4.16"
+
+ 7) Push the commit and tag by saying
+
+ git push --tags origin master
+
+ assuming the remote for the upstream libdrm repo is called origin.
+
+ 6) Use the release.sh script from the xorg/util/modular repo to
+ upload the tarballs to the freedesktop.org download area and
+ create an annouce email template. The script takes three
+ arguments: a "section", the previous tag and the new tag we just
+ created. For 2.4.16 again, the command is:
+
+ ../modular/release.sh libdrm 2.4.15 2.4.16
+
+ This copies the two tarballs to freedesktop.org and creates
+ libdrm-2.4.16.announce which has a detailed summary of the
+ changes, links to the tarballs, MD5 and SHA1 sums and pre-filled
+ out email headers. Fill out the blank between the email headers
+ and the list of changes with a brief message of what changed or
+ what prompted this release. Send out the email and you're done!

+Quick Guide To Patching This Package For The Impatient
+------------------------------------------------------
+
+1. Make sure you have quilt installed
+2. Unpack the package as usual with "dpkg-source -x"
+3. Run the "patch" target in debian/rules
+4. Create a new patch with "quilt new" (see quilt(1))
+5. Edit all the files you want to include in the patch with "quilt edit"
+ (see quilt(1)).
+6. Write the patch with "quilt refresh" (see quilt(1))
+7. Run the "clean" target in debian/rules
+
+Alternatively, instead of using quilt directly, you can drop the patch in to
+debian/patches and add the name of the patch to debian/patches/series.
+
+------------------------------------
+Guide To The X Strike Force Packages
+------------------------------------
+
+The X Strike Force team maintains X packages in git repositories on
+git.debian.org in the pkg-xorg subdirectory. Most upstream packages
+are actually maintained in git repositories as well, so they often
+just need to be pulled into git.debian.org in a "upstream-*" branch.
+Otherwise, the upstream sources are manually installed in the Debian
+git repository.
+
+The .orig.tar.gz upstream source file could be generated using this
+"upstream-*" branch in the Debian git repository but it is actually
+copied from upstream tarballs directly.
+
+Due to X.org being highly modular, packaging all X.org applications
+as their own independent packages would have created too many Debian
+packages. For this reason, some X.org applications have been grouped
+into larger packages: xutils, xutils-dev, x11-apps, x11-session-utils,
+x11-utils, x11-xfs-utils, x11-xkb-utils, x11-xserver-utils.
+Most packages, including the X.org server itself and all libraries
+and drivers are, however maintained independently.
+
+The Debian packaging is added by creating the "debian-*" git branch
+which contains the aforementioned "upstream-*" branch plus the debian/
+repository files.
+When a patch has to be applied to the Debian package, two solutions
+are involved:
+* If the patch is available in one of the upstream branches, it
+ may be git'cherry-picked into the Debian repository. In this
+ case, it appears directly in the .diff.gz.
+* Otherwise, the patch is added to debian/patches/ which is managed
+ with quilt as documented in /usr/share/doc/quilt/README.source.
+
+quilt is actually invoked by the Debian X packaging through a larger
+set of scripts called XSFBS. XSFBS brings some other X specific
+features such as managing dependencies and conflicts due to the video
+and input driver ABIs.
+XSFBS itself is maintained in a separate repository at
+ git://git.debian.org/pkg-xorg/xsfbs.git
+and it is pulled inside the other Debian X repositories when needed.
+
+The XSFBS patching system requires a build dependency on quilt. Also
+a dependency on $(STAMP_DIR)/patch has to be added to debian/rules
+so that the XSFBS patching occurs before the actual build. So the
+very first target of the build (likely the one running autoreconf)
+should depend on $(STAMP_DIR)/patch. It should also not depend on
+anything so that parallel builds are correctly supported (nothing
+should probably run while patching is being done). And finally, the
+clean target should depend on the xsfclean target so that patches
+are unapplied on clean.
+
+When the upstream sources contain some DFSG-nonfree files, they are
+listed in text files in debian/prune/ in the "debian-*" branch of
+the Debian repository. XSFBS' scripts then take care of removing
+these listed files during the build so as to generate a modified
+DFSG-free .orig.tar.gz tarball.

+ *
+ * DESCRIPTION
+ *
+ * This file contains a straightforward implementation of a fixed-sized
+ * hash table using self-organizing linked lists [Knuth73, pp. 398-399] for
+ * collision resolution. There are two potentially interesting things
+ * about this implementation:
+ *
+ * 1) The table is power-of-two sized. Prime sized tables are more
+ * traditional, but do not have a significant advantage over power-of-two
+ * sized table, especially when double hashing is not used for collision
+ * resolution.
+ *
+ * 2) The hash computation uses a table of random integers [Hanson97,
+ * pp. 39-41].
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * With a table size of 512, the current implementation is sufficient for a
+ * few hundred keys. Since this is well above the expected size of the
+ * tables for which this implementation was designed, the implementation of
+ * dynamic hash tables was postponed until the need arises. A common (and
+ * naive) approach to dynamic hash table implementation simply creates a
+ * new hash table when necessary, rehashes all the data into the new table,
+ * and destroys the old table. The approach in [Larson88] is superior in
+ * two ways: 1) only a portion of the table is expanded when needed,
+ * distributing the expansion cost over several insertions, and 2) portions
+ * of the table can be locked, enabling a scalable thread-safe
+ * implementation.

+ *
+ * DESCRIPTION
+ *
+ * This file contains a simple, straightforward implementation of the Park
+ * & Miller "Minimal Standard" PRNG [PM88, PMS93], which is a Lehmer
+ * multiplicative linear congruential generator (MLCG) with a period of
+ * 2^31-1.
+ *
+ * This implementation is intended to provide a reliable, portable PRNG
+ * that is suitable for testing a hash table implementation and for
+ * implementing skip lists.
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * If initial seeds are not selected randomly, two instances of the PRNG
+ * can be correlated. [Knuth81, pp. 32-33] describes a shuffling technique
+ * that can eliminate this problem.
+ *
+ * If PRNGs are used for simulation, the period of the current
+ * implementation may be too short. [LE88] discusses methods of combining
+ * MLCGs to produce much longer periods, and suggests some alternative
+ * values for A and M. [LE90 and Sch92] also provide information on
+ * long-period PRNGs.
