Hi Dmitry,
sorry to barge in but I just wanted to let you know that I
gave this series a try on the Motorola Moto X 2014 (victara,
MSM8974PRO-AC, PM8941 + PM8841) on top of v7.3-rc7 with the
msm8974-mainline patches and "clk: qcom: mmcc-msm8974: add
GENPD_FLAG_NO_STAY_ON".
Display (command mode panel) works through the MDP IOMMU. The GPU
works too: the Sailfish OS compositor renders on freedreno (Mesa
25.1.8) through the GPU IOMMU, and I don't see the reboot reported
on FP2. I tried 3D acceleration, and it works without issues.
Hope that helps!
Thanks,
Michał
