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().)

uncachedev: uncache test tool. 2013-03-12T13:47:01+00:00 Glenn Elliott gelliott@cs.unc.edu 2013-03-08T06:25:35+00:00 072b486393ab702eea9ea0a7fef569dbf8be0a32 This adds the uncache test tool (bin/uncache.c). The tool can be used to test Litmus's char device driver for allocating uncacheable CPU memory. The tool runs various checks and gathers basic cache vs. main memory statistics. In the future, uncache could be extended to quantify the benefits of the L1, L2, and L3 caches, instead of treating them as a black box. Note: Uncache works best when compiled with '-O2'. While '-O2' has not been added to the Makefile, other code was updated (code in tests/ and rtspin), to compile with -O2. DEPENDS UPON LITMUS-RT PATCH 888d097deb6d1fdc0c89a4f9667fd81cf416cfc7.

Add basic locking support to rtspin 2013-02-04T14:11:46+00:00 Bjoern Brandenburg bbb@mpi-sws.org 2013-01-14T13:56:17+00:00 f308b757af1574632627b727c90e08a65b1dfc96 This is useful for testing locking protocol implementations (not intended for benchmarking!), and also serves to document how to use the LITMUS^RT locking API.

This is no longer required. While at it, simplify the code by using the /proc interface.
