Subject: [PATCH v3 0/5] Add support for the ARMv8.2 Statistical Profiling Extension
Date: Thu, 18 May 2017 18:24:28 +0100 [thread overview]
Message-ID: <1495128273-13941-1-git-send-email-will.deacon@arm.com> (raw)
Hi all,
This is the fifth 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
v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/483684.html
v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-April/499938.html
Changes since v2 include:
* Rebased onto v4.12-rc1, which includes some rework to AUX flag
handling
* Removed VHE-dependent exclude_hv support in light of recent change
to CPU PMU code [1]
The architecture documentation is available here:
https://developer.arm.com/products/architecture/a-profile/docs/ddi0586/latest/arm-architecture-reference-manual-supplement-statistical-profiling-extension-for-armv8-a
and there's a high-level overview on this official ARM blog:
https://community.arm.com/processors/b/blog/posts/statistical-profiling-extension-for-armv8-a
All comments welcome,
Will
