Hi all,
This is the fourth 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
Changes since v1 include:
* Rebased onto new perf_aux_output_flag API (in -next via -tip and included here) * Fixed allocation of COLLISION flag * Fixed buffer draining in IRQ handler * Rebased onto v4.11-rc5
The architecture documentation is now 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
