* arch: sparc: Remove CONFIG_OPROFILE supportViresh Kumar2021-01-291-87/+0
| | | | | | | | | | | | | | | | 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()Paul E. McKenney2018-11-081-1/+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.

* sparc64: Manage NMI watchdog enabling like x86.David S. Miller2009-09-081-1/+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>

| | | | | | | 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>

| | | | | | | | | | 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>
