I was not able to test it on my own, this is a call for testing for the owners of these platforms. The git version of modetest now fully supports writeback. Use libdrm >= 2.4.117, run modetest -ac to determine the writeback connector, cat /sys/kernel/debug/dri/0/state to determine spare CRTC and plane, then run something like: modetest -M msm -a -s 36@85:1024x768 -o test.d -P 79@85:1024x768 where 36 is the Writeback connector id, 85 is CRTC and 79 is the plane. Then press Enter and check the test.d file for the raw image dump. Changes since v1: - Fixed the DPU_CLK_CTRL_WB2 definition
I think this series needs to be re-based as WB_SDM845_MASK is no longer present in msm-next and 3/4 patches in this series use that.
