Subject: [PATCH RFT 0/5] drm/msm: Attach a driver to GMU
Date: Wed, 13 May 2026 02:22:55 +0530 [thread overview]
Message-ID: <20260513-gmu-sync-state-fix-v1-0-6e33e6aa9b4f@oss.qualcomm.com> (raw)
With the introduction of sync_state in the genpd framework, any consumer
device of GCC and GPUCC which is not bound to a driver will result in
bootup warnings like below:
[ 24.362666] gcc-kaanapali 100000.clock-controller: sync_state() pending due to 3d37000.gmu
[ 24.371210] gxclkctl-kaanapali 3d64000.clock-controller: sync_state() pending due to 3d37000.gmu
[ 24.380268] gpucc-kaanapali 3d90000.clock-controller: sync_state() pending due to 3d37000.gmu
To silence these warnings and also to have a proper state in driver core,
attach a driver to the GMU and set it up as a component device for the drm
master device.
The first few patches are preparatory fixes and refactorings. And the
final patch introduces a driver for GMU devices.
