Hi Dmitry,
As written on IRC, on sdm632-fairphone-fp3 with this DPU patches the screen is
initializing and displaying stuff :) But there's some errors, which presumably
are the reason that the screen is only updating a few times per second.
[ 22.774205] [drm:dpu_kms_hw_init:1164] dpu hardware revision:0x10100000
[ 23.099806] [drm:_dpu_encoder_phys_cmd_wait_for_ctl_start:657] [dpu error]enc31 intf1 ctl start interrupt wait failed
[ 23.099821] [drm:dpu_kms_wait_for_commit_done:495] [dpu error]wait for commit done returned -22
These messages appear about 13 times per second but as I mentioned, the screen
*is* updating (slowly) there.
Also you for sure forgot to add "qcom,msm8953-mdp5" to the
msm_mdp5_dpu_migration list, without this DPU is never even considered for
8953.
Regards
Luca
