2018-11-08sparc/oprofile: Convert timer_stop() to use synchronize_rcu()Paul E. McKenney1-1/+1
Now that synchronize_rcu() waits for preempt-disable regions of code in addition to explicitly marked RCU read-side critical sections, synchronize_rcu() can be used in place of synchronize_sched(). This commit therefore makes that change. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com> Cc: Robert Richter <rric@kernel.org> Cc: "David S.

2009-09-08sparc64: Manage NMI watchdog enabling like x86.David S. Miller1-1/+1
Use a per-cpu 'wd_enabled' boolean and a global atomic_t count of watchdog NMI enabled cpus which is set to '-1' if something is wrong with the watchdog and it can't be used. Signed-off-by: David S. Miller <davem@davemloft.net>

2009-01-28sparc64: Move generic PCR support code to seperate file.David S. Miller1-107/+3
It all lives in the oprofile support code currently and we will need to share this stuff with NMI watchdog and perf_counter support. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-04sparc64: Use NMI oprofile profiling on cheetah and derivative cpus.David S. Miller1-1/+109
We use clock cycle counter, adjusted to HZ. This can be extended to sun4v based processors as well, as they also have a proper overflow interrupt facility for the performance counters. Signed-off-by: David S. Miller <davem@davemloft.net>
