liblitmus.git, branch ecrts14-pgm-final [ARCHIVE] The userspace library for LITMUS^RT 2010. Now on GitHub. Add support for job splitting. 2014-02-19T20:53:00+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-11-26T19:42:45+00:00 ecfe8654b8d9e433967792f8087b17e4dac3f076 This patch adds support for job splittinig schedulers. The default split factor for jobs is 1 (unchanged behavior).

Update PGM interface with kernel 2014-02-19T20:51:25+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-11-19T19:10:33+00:00 6a76ccc5091bd352860b7d74946c99d9d6e83369 This patch updates the PGM interface with the kernel. Producers now boost their priority when generating tokens, not consumers while waiting for tokens.

Add additional time unit conversion macros. 2014-02-19T20:51:25+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-09-27T18:08:08+00:00 8edeea97158cfe9fbb15aea57bb77fcc346cfc9a Adds macros for converting smaller time units into bigger ones (ex. ns to s).

Fix for C++: 'namespace' renamed to 'name_space' 2014-02-19T20:51:25+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-09-27T18:00:55+00:00 7975afcc7d68efc64a4258d2c593079774fec08f Renames the 'namespace' parameter to litmus_open_lock() forard declaration in litmus.h to 'name_space'. This allows litmus.h to be compiled by a C++ compiler. (Note: Using 'extern "C" {}' does not work as an alternative solution.)

Update tools for new affinity mask method. 2014-02-05T05:34:51+00:00 Glenn Elliott gelliott@cs.unc.edu 2014-02-05T05:34:51+00:00 230866900a5b1e2a65f53110e295e83718a515de Cluster size no longer needs to be provided now that cluster/CPU mappings are explicit in /proc/litmus/domains/.

Use /proc/litmus/domains to set up affinity masks. 2014-02-05T05:34:37+00:00 Glenn Elliott gelliott@cs.unc.edu 2014-02-05T05:31:08+00:00 81c3862197756046eee4a2dd9114fa7ccedf5b85 This patch replaces the algorithm used to compute CPU affinity masks. The old algorithm was fragile and would break on systems with multiple levels of shared caches. (As found on some older Intel chips, and as one would probably find on a system with hyper-threading enabled.) The bug stems from fact that Linux enumerates consecutive CPUs in a way that distributes them across the physical system, thereby reducing contention resources (e.g., cache).

Port Makefile to new Linux kernel header layout 2013-07-11T12:51:06+00:00 Bjoern Brandenburg bbb@mpi-sws.org 2013-07-11T12:51:06+00:00 068cfc3f190cb901c9ab36e76db01bb09373e0f9 The userspace versions of unistd.h have moved to include/uapi/asm in recent kernel versions; we need to adjust the liblitmus Makefile accordingly. Further, on x86, the unistd_32.h and unistd_64.h files are now actually being auto-generated; this also forced adjustments. This patch is required for liblitmus to compile against Linux 3.10.
