Each of them follows ARM SMMU v1 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
