Subject[GIT PULL v6] hw-breakpoints: Rewrite on top of perf events v6
Date
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().
