Hi! I'd like to announce a couple of updates that were recently made to the build scripts on the ofed_kernel branch. This is an attempt to answer repeated requests, aired at Sonoma, to simplify access to kernel sources.
The idea is that a user of a supported kernel will just be able to download an appropriate tarball and run with it without need for patching. These changes are available from ofed_kernel git tree maintained by Vlad: git://git.openfabrics.org/~vlad/ofed_kernel.git ofed_kernel The code is mine, but the ideas mostly come from criticism and code sent by Ira Weiny. Thanks, Ira! Note that the changes were made in a backwards-compatible way, so that existing scripts using configure/make will continue working. What's new: 1. New script ofed_scripts/ofed_patch.sh This will apply fixes and backport patches for a specific kernel to the current tree. Usage: ./ofed_scripts/ofed_patch.sh --with-backport=VERSION This makes it possible for distro vendors to generate a tarball pre-patched for a specific kernel. 2. New script ofed_scripts/ofed_makedist.sh This script repeatedly clones the current repository, runs ofed_scripts/ofed_patch.sh, and then builds tarballs of ofed kernel source pre-patched for supported kernel versions. I plan to work with Vlad to run this script as part of nightly builds, so that prepatched tarballs will become available for download. 3. configure script made re-entrant configure script does not apply patches anymore: all it does is create configure.mk.kernel and autoconf.h files. This finally makes it possible to change configuration parameters just by re-running configure. For backwards-compatibility, if configure detects that ofed_scripts/ofed_patch.sh was not run yet, it prints a warning and runs it automatically. Feedback wellcome. -- MST _______________________________________________ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
