From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yu Chien Peter Lin Date: Wed, 22 Nov 2023 15:36:02 +0800 Subject: [PATCH v3 00/15] Add Andes PMU extension support Message-ID: <20231122073617.379441-1-peterlin@andestech.com> List-Id: To: opensbi@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit 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 mainly fixes single-core freeze when quitting 'perf top', adds andes_pmu_setup() to provide default event mappings when fdt_pmu_setup() can't find PMU node. And add Xandespmu to hart extension list so that the inhibit bits can be updated in a similar way to how Smcntrpmf does. The last patch provides a PMU node example used on AX45MP cores.
