| * P-FP: fix BUG_ON releated to priority inheritancearchive/unc-master-3.0Bjoern Brandenburg2013-02-04
| | | | | | | | | | | | | | In some cases, the PCP priority inheritance code triggered a (defensive) BUG_ON() in fp_common.c. This shuffles the order of operations a bit to be compliant with the restriction that tasks are never compared against themselves.
| * FDSO: fail to build if some ops are missingBjoern Brandenburg2013-02-04
| | | | | | | | Prevents out-of-bounds lookups.
| * TRACE_TASK(): accept NULL pointersBjoern Brandenburg2013-02-04
| | | | | | | | Allow tracing of NULL tasks. Makes debugging a bit easier.

| | | | | | | | | | Tasks that immediatly acquired a free replica were not being counted as being in the FIFOs.
* | part. gpu hack and fixed dumb ikglp bugGlenn Elliott2013-01-28
| | | | | | | | | | | | IKGLP wasn't being passed the right value for 'm' in C-EDF. It went undected for so long since m < k in our GPUSync experiments.

* | Fix inheritance propagation for klmirqd&aux tasks.Glenn Elliott2013-01-24
| | | | | | | | | | | | | | | | | | | | Bug: Inheritance not propagated to klmirqd and aux tasks when the task these threads inherit from has a change in its own priority. (Also removed per-task NV interrupt tracking since we cannnot identify exact interrupt ownership under GPUSync.)
* | Fix AUX tasks from being dropped by Litmus.Glenn Elliott2013-01-23
| |
* | Fixed case where blocked tasks are released.Glenn Elliott2013-01-21
| | | | | | | | | | | | | | | | | | | | Fixed bug where AUX tasks were being added to the ready queue while those AUX tasks were actually blocked. Bug stems from the fact that the AUX tasks do not make themselves realtime, but another thread does this instead. Also fixed minor bugs elsewhere. NOTE: ONLY FIXES C-EDF. OTHER PLUGINS REMAIN TO BE FIXED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Deadlock in litmus_task_exit()-- added litmus_pre_task_exit() to be called without the Linux runqueue lock held. 2) Prioritization of base-prio klmirqd/aux threads vs. normal real-time tasks. 3) Initialization of gpu owner binheap node moved to *after* memset(0) of rt_params. 4) Exit path of klmirqd threads.

| | | | | | | | | | | | | | | | | | | | | | | | This patch causes reboot notifications to be send to Litmus. With this patch, Litmus attempts to switch back to the Linux-plugin before the reboot proceeds. Any failures to switch back are reported via printk() (the reboot is not halted).

| * | Fixed three bugs with aux threads and nested locksGlenn Elliott2012-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes two bugs with nested locks: 1) List of aux threads could become corrupted. -- moved modifications to be within scheduler lock. 2) Fixed bad EDF comparison ordering that could lead to schedule thrashing in an infinite loop. 3) Prevent aux threads from inheriting a priority from a task that is blocked on a real-time litmus lock. (since the aux threads can't possibly hold these locks, we don't have to worry about inheritance.)

| | * | Do processor state transitions in schedule_tail().Glenn Elliott2012-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a bug in Litmus where processor scheduling states could become corrupted. Corruption can occur when a just-forked thread is externally forced to be scheduled by SCHED_LITMUS before this just-forked thread can complete post-fork processing. Specifically, before schedule_tail() has completed.

| | | | | | | | | | | | | | | | | | | | | | | | Auxillary task features were enabled by CONFIG_LITMUS_LOCKING. Made auxillary tasks a seperate feature that depends upon CONFIG_LITMUS_LOCKING.
