arm: perf: factor arm_pmu core out to drivers To enable sharing of the arm_pmu code with arm64, this patch factors it out to drivers/perf/. A new drivers/perf directory is added for performance monitor drivers to live under. MAINTAINERS is updated accordingly. Files added previously without a corresponsing MAINTAINERS update (perf_regs.c, perf_callchain.c, and perf_event.h) are also added.

drivers/perf: arm_pmu: add ACPI framework This patch adds framework code to handle parsing PMU data out of the MADT, sanity checking this, and managing the association of CPUs (and their interrupts) with appropriate logical PMUs. For the time being, we expect that only one PMU driver (PMUv3) will make use of this, and we simply pass in a single probe function. This is based on an earlier patch from Jeremy Linton.

Provides support for the L2 cache performance monitor unit (PMU)

Adds the L2 cache PMU into the perf events subsystem for
monitoring L2 cache events.
perf: qcom: Add L3 cache PMU driver This adds a new dynamic PMU to the Perf Events framework to program and control the L3 cache PMUs in some Qualcomm Technologies SOCs. The driver supports a distributed cache architecture where the overall cache for a socket is comprised of multiple slices each with its own PMU. Access to each individual PMU is provided even though all CPUs share all the slices. User space needs to aggregate to individual counts to provide a global picture. The driver exports formatting and event information to sysfs so it can be used by the perf user space tools with the syntaxes: perf stat -a -e l3cache_0_0/read-miss/ perf stat -a -e l3cache_0_0/event=0x21/ Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Agustin Vega-Frias <agustinv@codeaurora.org> [will: fixed sparse issues] Signed-off-by: Will Deacon <will.deacon@arm.com>
