Hi Moudy Ho, Thank you for your patch. Missatge de Moudy Ho <moudy.ho@xxxxxxxxxxxx> del dia dl., 19 de jul. 2021 a les 9:47: > > This patch adds driver for Media Data Path 3 (MDP3). What's Media Data Path? What's this driver for? Is it a ISP? Is for video-decoding? What are the real capabilities of the MDP HW block? > Each modules' related operation control is sited in mtk-mdp3-comp.c > Each modules' register table is defined in file with "mdp_reg_" > and "mmsys_" prefix > GCE related API, operation control sited in mtk-mdp3-cmdq.c > V4L2 m2m device functions are implemented in mtk-mdp3-m2m.c > Probe, power, suspend/resume, system level functions are defined in > mtk-mdp3-core.c > That's explaining a bit how is organized but you are not explaining why. That's the important to explain here. It'd be really nice if you can explain a bit how do you test this driver and also explain the general architecture of this driver you have in mind. Why you are exposing the MDP HW directly as a V4L2 device to userspace, who needs that and why. > Signed-off-by: Ping-Hsun Wu <ping-hsun.wu@xxxxxxxxxxxx> > Signed-off-by: daoyuan huang
