Subject[PATCH v6 0/7] Add support for the ARMv8.2 Statistical Profiling Extension
Date
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
