> Subject: [PATCH v3 0/2] perf: ARM CoreSight PMU support
>
> Add driver support for ARM CoreSight PMU device and event attributes for
> NVIDIA
> implementation. The code is based on ARM Coresight PMU architecture and
> ACPI ARM
> Performance Monitoring Unit table (APMT) specification below:
> * ARM Coresight PMU:
> https://developer.arm.com/documentation/ihi0091/latest
> * APMT: https://developer.arm.com/documentation/den0117/latest
>
> Notes:
> * There is a concern on the naming of the PMU device.
> Currently the driver is probing "arm-coresight-pmu" device, however the
> APMT
> spec supports different kinds of CoreSight PMU based implementation. So
> it is
> open for discussion if the name can stay or a "generic" name is required.
> Please see the following thread:
> http://lists.infradead.org/pipermail/linux-arm-kernel/2022-
> May/740485.html
>
> The patchset applies on top of
> https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
> master next-20220524
>
> Changes from v2:
> * Driver is now probing "arm-system-pmu" device.
> * Change default PMU naming to "arm_<APMT node type>_pmu".
> * Add implementor ops to generate custom name.
> Thanks to suzuki.poulose@arm.com for the review comments.
>
> Changes from v1:
> * Remove CPU arch dependency.
> * Remove 32-bit read/write helper function and just use read/writel.
> * Add .is_visible into event attribute to filter out cycle counter event.
> * Update pmiidr matching.
> * Remove read-modify-write on PMCR since the driver only writes to
> PMCR.E.
> * Assign default cycle event outside the 32-bit PMEVTYPER range.
> * Rework the active event and used counter tracking.
> Thanks to robin.murphy@arm.com for the review comments.
