Subject: [PATCH 00/10] Add support for the ARMv8.2 Statistical Profiling Extension
Date: Fri, 27 Jan 2017 18:07:39 +0000 [thread overview]
Message-ID: <1485540470-11469-1-git-send-email-will.deacon@arm.com> (raw)
Hi all,
This is the third posting of the patches previously posted here:
rfcv1: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/476450.html
rfcv2: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/479387.html
Changes since RFCv2 include:
* Change compatible string
* Renamed PMU
* Simplified EL2 init code
* Dropped the RFC tag
* Added acks
There's also now an official ARM blog giving a high-level overview of
what SPE is:
https://community.arm.com/processors/b/blog/posts/statistical-profiling-extension-for-armv8-a
All comments welcome,
Will

arm64: cpufeature: allow for version discrepancy in PMU
implementations

arm64: head.S: Enable EL1 (host) access to SPE when entered at EL2
genirq: export irq_get_percpu_devid_partition to modules
perf/core: Export AUX buffer helpers to modules
perf: Directly pass PERF_AUX_* flags to perf_aux_output_end
perf/core: Add PERF_AUX_FLAG_COLLISION to report colliding samples
drivers/perf: Add support for ARMv8.2 Statistical Profiling Extension
dt-bindings: Document devicetree binding for ARM SPE
