Subject: [PATCH v3] drm/msm: add PERFCTR_CNTL to ifpc_reglist
Date: Thu, 27 Nov 2025 19:22:35 +0100 [thread overview]
Message-ID: <20251127-ifpc_counters-v3-1-fac0a126bc88@gmail.com> (raw)
Previously this register would become 0 after IFPC took place which
broke all usages of counters.
Fixes: a6a0157cc68e ("drm/msm/a6xx: Enable IFPC on Adreno X1-85")
Cc: stable@vger.kernel.org
