Subject: Claude review: drm/hibmc: Fix list of formats on the primary plane
Date: Thu, 23 Apr 2026 10:03:23 +1000 [thread overview]
Message-ID: <review-patch2-20260420121130.200133-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20260420121130.200133-3-tzimmermann@suse.de>
Patch Review
**Status: Good**
Reduces the format list from 10 entries to 2:
```c
static const u32 channel_formats1[] = {
DRM_FORMAT_XRGB8888,
DRM_FORMAT_RGB565,
};
```
The commit message provides clear justification for each removal:
- Alpha formats (ARGB8888, RGBA8888, etc.): no transparency support in the plane implementation.
- BGR formats: no BGR channel order support in the implementation.
- RGB888: the `cpp[0] * 8 / 16` formula in `atomic_update` computes `3 * 8 / 16 = 1` (truncated), which programs the hardware for RGB565, producing distorted output.
All three categories are genuine bugs where the driver advertises formats it can't correctly handle. The Cc: stable tag is appropriate. Correctly carries a Fixes tag.
No issues.
