Hi all,
This is the 8th 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 v3: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-May/507132.html v4: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-June/510799.html v5: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-September/533478.html
The only change since v5 is the addition of Acked-by tags, so I'd like to queue this soon.
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
Cheers,
Will
