Ingo,
Please pull the tracing/hw-breakpoints branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git tracing/hw-breakpoints
Changes in v6:
- Fix wrong header inclusion in trace.h (triggered a build error with CONFIG_FTRACE_SELFTEST)
- Currently, events scheduling are done in this order: cpu context pinned + cpu context non-pinned + task context pinned + task context non-pinned events. Then our current constraints are right theoretically but not in practice, because non-pinned counters may be scheduled before we can apply every possible pinned counters. So consider non-pinned counters as pinned for now (thanks Paul for reporting this)
Thanks, Frederic ---
Frederic Weisbecker (4): perf/core: Add a callback to perf events hw-breakpoint: Move asm-generic/hw_breakpoint.h to linux/hw_breakpoint.h hw-breakpoints: Rewrite the hw-breakpoints layer on top of perf events hw-breakpoints: Arbitrate access to pmu following registers constraints
Arjan van de Ven (1): perf/core: Provide a kernel-internal interface to get to performance counters
Li Zefan (1): ksym_tracer: Remove KSYM_SELFTEST_ENTRY
Paul Mundt (1): x86/hw-breakpoints: Actually flush thread breakpoints in flush_thread().
