Subject: [PATCH RESEND 2/2] drm/msm/adreno: Add power management functions for system sleep
Date: Mon, 28 May 2018 21:53:39 +0200 [thread overview]
Message-ID: <20180528195339.22094-2-daniel@zonque.org> (raw)
In-Reply-To: <20180528195339.22094-1-daniel@zonque.org>
When a msm8016 based system is woken up from suspend, the firmware in
the adreno device hangs.
[ 83.903416] qcom-iommu-ctx 1f09000.iommu-ctx: Unhandled context fault: fsr=0x202, iova=0x0000000000000000, fsynr=0x2, cb=1
[ 85.853633] msm 1a00000.mdss: A306: hangcheck detected gpu lockup rb 0!
[ 85.853661] msm 1a00000.mdss: A306: completed fence: 370
[ 85.859073] msm 1a00000.mdss: A306: submitted fence: 372
[ 85.865113] msm 1a00000.mdss: A306: hangcheck recover!
Fix this by adding pm_runtime_force_suspend/pm_runtime_force_resume
as sleep ops.
