rtspin: add -e option to enable PRECISE_ENFORCEMENT

2010-10-19T14:05:36+00:00

Useful to test how the kernel handles PRECISE_ENFORCEMENT.

zero out rt_task parameters before setting them

2010-09-22T16:46:02+00:00

This avoids passing random stack contents to the kernel
if the structure gained some fields due to plugin development.

(Also, fix up some white space issues while we are at it.)

Support budget enforcement policies. Allows tasks to specify

2010-05-20T18:17:58+00:00

how their execution budgets should be enforced: NO_ENFORCEMENT,
QUANTUM_ENFORCEMENT, and PRECISE_ENFORCEMENT (unsupported).

NOTE: Users of NO_ENFORCEMENT must call sleep_next_period() at the
end of every job to signal to the kernel that its job is complete.

Add atomic operations on x86_64

2010-04-19T23:28:07+00:00

Add cli() and sti() wrappers... use with care...

2010-04-13T03:31:52+00:00

Add get_control_page() library function

2010-04-13T03:30:36+00:00

Improve build system.

2010-03-17T16:48:44+00:00

Restructure SConstruct to reduce the likelihood
of errors and to provide additional feedback.
Features:
- Better help. You can now run 'scons -h' to
  get a listing of all build options.
- Local configuration. Build variables are picked up
  in a local .config file, if present.
- Added --dump-config option to display the build
  configuration.
- Use scons substitution system to avoid having to do
  parameter substitutions manually.
- Some assorted fixes.

Merge branch 'master' of ssh://cvs.cs.unc.edu/cvs/proj/litmus/repo/liblitmus2010

2010-03-10T23:48:33+00:00

Add -v (verbose) switch to rtspin.

2010-03-10T23:47:45+00:00

Can be used to dump the delay loop that rtspin
is using.

Build fix: support building on i686 systems

2010-03-10T12:26:41+00:00

32bit Intel systems don't actually report 'x86' as
their architecture, rather, they are i?86 systems.
Provide a lookup table to map these codes to the
'x86' name that is used in the SConstruct file.
