Fix compile failure related to aliasing (gcc 4.4.5) 2013-04-17T16:01:47+00:00 Bjoern Brandenburg bbb@mpi-sws.org 2013-04-17T15:58:46+00:00 6d5c51fa0ae84a98f4200d39de4eb2b75e369753 My version of gcc would complain about "dereferencing pointer does break strict-aliasing rules" because of a (harmless) pointer cast. This patch adds a helper void pointer to make the assignment explicit, which avoids the cast and hence silences the warning.

Change convenience API routines. 2013-03-12T17:42:34+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-03-12T17:13:22+00:00 0e71f86251307a37161cf3de2704a59882e25258 The sproadic_*() macros have become unwieldy. This patch replaces those convenience macros for global, clustered, and partitioned scheduling. A part of this API change is the explicit use of nanosecond time-values. Prior APIs have used lt_t (litmus time), which had an implied time scale of nanoseconds. /bin apps and test suite also updated to use revised API. Modifications to the test suite are mostly centered around using nanoseconds instead of milliseconds.

Cluster-aware rtspin and rt_launch. 2013-03-12T16:47:20+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-03-05T23:32:01+00:00 0a54a84457bb8a33113c7dd2a2b63b2a837cc92e This patch adds cluster scheduling options to rtspin and rt_launch. The convenience routines in litmus.h were also updated to facilitate clustered scheduling. For partitioned scheduling, just set cluster_size = 1 (default size for rtspin and rt_launch).

Auto-CPU-affinity from part./cluster assignment. 2013-03-12T16:02:20+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-03-12T15:57:42+00:00 93ffe5be8fd1954bbfe5a04e55b81ac1d83d2de7 This patch replaces be_migrate_to() with several be_migrate_*() APIs to automatically assign CPU affinity masks from a task's partition (or cluster) assignment. Routines are release-master-aware such that the release master (if one exists) will NOT be included in the task's affinity mask. (Note that release-master avoidance may be overridden by calling __be_migrate_thread_to_cluster().)
