| * | ARM: 7447/1: rwlocks: remove unused branch labels from trylock routines | Will Deacon | 2012-10-17 |
| | | | | | | | | | | | | | | The ARM arch_{read,write}_trylock implementations include unused backwards branch labels, since we don't retry the locking operation if the exclusive store fails. This patch removes the labels.

| * | ARM: 7446/1: spinlock: use ticket algorithm for ARMv6+ locking implementation | Will Deacon | 2012-10-17 |
| | | | | | | | | | | | | | | | | | | | | Ticket spinlocks ensure locking fairness by introducing a FIFO-like nature to the granting of lock acquisitions and also reducing the thundering herd effect when spinning on a lock by allowing the cacheline to remain in a shared state amongst the waiting CPUs. This is especially important on systems where memory-access times are not necessarily uniform when accessing the lock structure (for example, on a multi-cluster platform where the lock is allocated into L1 when a CPU releases it). This patch implements the ticket spinlock algorithm for ARM, replacing the simpler implementation for ARMv6+ processors.

| * | 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> | ||
| * | Fixed sched_trace records for state transitions. | Jonathan Herman | 2012-10-15 |
| | | | | | This commit is dirty and will be cleaned up when blocking states are tested. | ||

| | | | | | | | | Note: Highmem pages will need to be vmapped in the kernel, or we need to not use HIGHMEM pages. Signed-off-by: Christopher Kenna <cjk@cs.unc.edu> | ||
