Subject: [PATCH v27 0/4] media: mediatek: support mdp3 on mt8183 platform
Change since v26:
- Set MMSYS config from "depend on" to "select" in MDP3 Kconfig
to avoid compilation errors of various combinations.
- Fix cast to smaller integer type 'enum mdp_comp_type' from
'const void *' in mtk_mdp3_comp.c.
- Fix sparse warnings in mtk_mdp3_comp.c.
- The v4l2-compliance test results are the same as v26.
Change since v25:
- Add more COMPILE_TEST config in MDP3 Kconfig
- Adjust unnecessary log level in "mdp_m2m_s_selection" function to
avoid spamming the kernel log for userspace errors.
- The v4l2-compliance test results list is as follows:
v4l2-compliance 1.23.0-4942, 32 bits, 32-bit time_t
v4l2-compliance SHA: 4cf258c24026 2022-07-28 15:43:45

- EC ipi cmd migration
- fix compliance test fail item (m2m cmd with -f) due to there is two problem in
runing all format(-f) cmd:
1. out of memory before test complete
Due to capture buffer mmap (refcount + 1) after reqbuf but seems
no corresponding munmap called before device close.
There are total 12XX items(formats) in format test and each format
alloc 8 capture/output buffers.
2. unceasingly captureBufs() (randomly)
Seems the break statement didn't catch the count == 0 situation:
In v4l2-test-buffers.cpp, function: captureBufs()
...
count--;
if (!node->is_m2m && !count)
break;
Log is as attachment
Hi,
This patch is used to present Media Data Path 3 (MDP3)
which provided scaling and color format conversion.
support using GCE to write register in critical time limitation.
support V4L2 m2m device control.
