[0/3] media: mediatek: vcodec: Add driver to support 10bit

  Define two capture formats V4L2_PIX_FMT_MT2110R and
V4L2_PIX_FMT_MT2110T to support 10bit in mt8195, mt8199 and more.
Getting the size of each plane again when userspace set 10bit
syntax to driver.

V4L2_PIX_FMT_MT2110R is used for H264, and V4L2_PIX_FMT_MT2110T
is used for AV1/VP9/HEVC.

patch 1 Add driver to support 10bit
patch 2 Add capture format V4L2_PIX_FMT_MT2110T to support 10bit tile mode
patch 3 Add capture format V4L2_PIX_FMT_MT2110R to support 10bit raster mode
---
- send the first version v1:
- Run 10bit VP9/AV1 fluster test pass.
- Will return error when the 10bit parameter no correctly in function mtk_vdec_s_ctrl.
---

Reference series:
[1]: this series depends on v6 which is send by Yunfei Dong.

Please at least provide the score before and after these changes. Full report is
also nice. You didn't explain why H.264 is not tested.

This cover letter is missing v4l2-compliance report. This is needed whenever
format mechanism is modified in a driver (not just for new drivers). Please add
and make sure there is not regression too.

Its seems like 6.5.0-rc1 with the depedency and this patchset does not boot on
MT8195 Chromebooks. Which paltform has this been validated on ?

> MT8195 Chromebooks. Which paltform has this been validated on ?

I've manged to boot it using Collabora for-kernel-ci next kernel, which is based
on media-state/master 6.5.0-rc1. I suspect there is more depedencies then
described which might be pending in other trees. As all the patches are from
other trees submission, I suppose this is fine for now. Notice that the boot log
does not look very promising though, I will do some more testing, but from clean
boot, after udev have filled the HW database:

[   10.399826] mt7921e 0000:01:00.0: WM Firmware Version: ____010000, Build Time: 20230117170942
[   11.882202] mtk-vcodec-dec 18000000.video-codec: [MTK_V4L2][ERROR] Not supported ctrl id: 0xa40903
[   11.882202] 
[   11.910945] mtk-vcodec-dec 18000000.video-codec: [MTK_V4L2][ERROR] Not supported ctrl id: 0xa40903

This is produced when udev calls /usr/lib/udev/v4l_id, I don't think its doing
anything that would explain error logs.

Nicolas

Are you sure this was caused by these patches?

I've recently noticed two issues that cause MT8195 Tomato to softlock the CPU
similar to your trace below.

One of them is caused by having CONFIG_ARM_DSU_PMU=m. Note that it is present in
the arm64 defconfig. To workaround, the config needs to be disabled.

The other is caused by commit 46600ab142f8 ("regulator: Set
PROBE_PREFER_ASYNCHRONOUS for drivers between 5.10 and 5.15"). The whole machine
gets really slow, including the serial. This issue only happens sometimes. To
workaround that commit can be reverted.

I intend to look into those issues and provide proper fixes in the following
days.

Thanks,
Nícolas

Just ran AV1 and VP8 tests locally. VP8 completely fails (0/61) as the update
rejects the VP8 controls in mtk_vdec_s_ctrl. As for AV1, it completely regressed
(0 success, there is "invalid tge_size" kind of errors). I've been testing with
the upstream firmware since you didn't mention any firmware update (md5 is
52d11ed015d4e2f6d4e9ce9a8fcf20e3).

You can retrace my step using this kernel and normal Debian OS:

This isn't set in my config.

  # CONFIG_ARM_DSU_PMU is not set

If by slow you mean the self stall detection triggers, maybe, I haven't spent
time studying the current delta from 6.5.0-rc1 and Collabora forci branch, but
its non-null. Also, applying the same patches on top did not break the boot, so
quite unlikely. Here's a snapshot of my branch I made, I simply revert some
conflicting  changes related to VP9 racing, then it applied cleanly.

Forgot to test v4l2-compliance, will add in next patch.

The flush test not include H264 for test fail, according to mingjia's
information, maybe gstreamer set wrong format. H264 fluster can test
pass when kernel driver force h264 in raster mode.

Test the patch series "separate encoder and decoder" and "Add driver to
support 10bit" in mt8188 and mt8195, the driver can work well with tast
test and Youtube. Not found the crash log. Maybe the crash log isn't
related with decoder?

For everyone interested, I've rebased MT2110R and MT2110T support MR in
GStreamer. With the offending "return -EINVAL" removed, the test passes for me.
Consider updating your GStreamer build, let me know if you see further issue
with GStreamer in this regard. I'm only missing a firmware with HEVC and 10bit
combined to confirm HEVC works too.
