Subject: [PATCH v2 00/11] Add Andes PMU extension support
Date: Thu, 19 Oct 2023 19:37:02 +0800 [thread overview]
Message-ID: <20231019113713.3508153-1-peterlin@andestech.com> (raw)
This patch series enables perf tool to utilize Andes PMU
extension via PMU SBI calls, provides PMU device callbacks
to achieve event sampling and mode filtering.
This version also introduces a platform override fdt_add_pmu_mappings()
to create event mappings before PMU setup if a valid PMU node
is missing.
The last patch provides a PMU node example used on AX45MP cores.
The OpenSBI and Linux patches can be found on Andes Technology GitHub
