arch: sparc: Remove CONFIG_OPROFILE support

2021-01-29T04:35:51Z

The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. Remove the old oprofile's architecture specific support.

sparc/oprofile: Convert timer_stop() to use synchronize_rcu()

2018-11-09T05:43:20Z

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 Cc: Robert Richter Cc: "David S. Miller" Cc: Cc:

sparc64: Manage NMI watchdog enabling like x86.

2009-09-09T06:16:06Z

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

sparc64: Move generic PCR support code to seperate file.

2009-01-29T01:13:57Z

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

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
