2020-06-19docs: arm64: convert perf.txt to ReST formatMauro Carvalho Chehab1-85/+0
This file is almost in ReST. All it needs is a rename and adding a :field: for the two fields at the beginning (author and date). While here, add a proper SPDX header, and use the standard markup for document titles, just for consistency.

2019-04-24arm64: docs: Document perf event attributesAndrew Murray1-0/+85
The interaction between the exclude_{host,guest} flags, exclude_{user,kernel,hv} flags and presence of VHE can result in different exception levels being filtered by the ARMv8 PMU. As this can be confusing let's document how they work on arm64.
