Hi Moudy, I noticed one more thing (and it is probably better to post a v26 after all): On 17/08/2022 11:56, Moudy Ho wrote: > This patch adds driver for MediaTek's Media Data Path ver.3 (MDP3). > It provides the following functions: > color transform, format conversion, resize, crop, rotate, flip > and additional image quality enhancement. > > The MDP3 driver is mainly used for Google Chromebook products to > import the new architecture to set the HW settings as shown below: > User -> V4L2 framework > -> MDP3 driver -> SCP (setting calculations) > -> MDP3 driver -> CMDQ (GCE driver) -> HW > > Each modules' related operation control is sited in mtk-mdp3-comp.c > Each modules' register table is defined in file with "mdp_reg_" 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 > > v4l2-compliance 1.22.1, 32 bits, 32-bit time_t First of all, the v4l2-compliance output belongs to the cover letter, not to a commit log for a patch. More importantly, I can tell that v4l2-compliance was a prepackaged version, but you need to compile it from the git repo yourself: git clone git://linuxtv.org/v4l-utils.git cd v4l-utils ./bootstrap.sh ./configure make sudo make install Running v4l2-compliance should start with this (or something close): v4l2-compliance 1.23.0-4941, 64 bits, 64-bit time_t v4l2-compliance SHA: 71112d214762 2022-07-28 15:31:13 I need to see the SHA to confirm that you tested with a sufficiently new v4l2-compliance version. Prepackaged v4l2-compliance binaries tend to be too old, at least for the purpose of compliance checking a new driver.
