From d5d12a91d101764678cb7336fc916bada071911b Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Thu, 22 Dec 2022 12:38:50 -0800 Subject: [PATCH] docs: pmu: Update the pmu doc with removal of mcountinhbit restriction Since commit b28f070, it is possible for platforms to run perf monitoring even if mcountinhibit is not supported. Sampling still won't be possible though as it requires sscofpmf extension. Update the docs to remove the restriction.
