| * | Changes to ARM lockdown and LITMUS cycle counting code. | Christopher Kenna | 2012-10-17 |
| | | | | | | | | | | | Try and fix the cycle counter on ARMv7 CPUs (unsuccessful). Use the multi-core timer on the ODROID-X to count cycles. Add lockdown register access to proc. Add proc options to disable prefetching for L1/L2 cache. Add test to lockdown.c to print the time to read in various WSSs. Signed-off-by: Christopher Kenna <cjk@cs.unc.edu> | ||

| * | Architecture dependent uncachable control page. | Christopher Kenna | 2012-10-07 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | While working on an ODROID-X (Samsung Exynos4412 ARM Cortex-A9), I experienced non-determinism when reading and writing values to the LITMUS^RT control page. Writes to the control page from user- (kernel-) space where not always reflected in kernel- (user-) space. Neither restricting the task to run on a single CPU nor inserting general memory barriers (with mb()) fixed the problem. Mapping the control page as uncachable in both kernel and user space did fix the problem, which is what this patch does. Also, since vunmap() cannot be called from an interrupt context, I had to add a workqueue that unmaps and frees the control page when it is no longer needed. (On my system, exit_litmus() was called from interrupt context while the kernel reaped the task_struct.) Conflicts: include/litmus/rt_param.h litmus/litmus.c Does not make the color control page uncachable yet! Signed-off-by: Christopher Kenna <cjk@cs.unc.edu> | ||

| |/ | | | | | | Both sched_color and sched_mc assumed seperate kernel and userspace views of job states, where the kernel view is used for scheduling while the userspace view is used for statistics (tardiness etc). This commit merges both approaches. | ||
