drm: Remove drm_get_format_name()

2021-05-27T06:34:50Z

The %p4cc printk format modifier was recently added to print fourcc codes, replacing drm_get_format_name(). The function is no longer needed, so remove it.

drm/fourcc: Fix the parameters name in the documentation

2019-05-21T14:58:05Z

We introduced new functions in the commit bf39607c1614 ("drm/fourcc: Pass the format_info pointer to drm_format_plane_width/height") based on previous ones but with a slightly different prototype. However, the documentation wasn't changed to reflect that change.

drm/fourcc: Pass the format_info pointer to drm_format_plane_width/height

2019-05-20T11:35:24Z

So far, the drm_format_plane_height/width functions were operating on the format's fourcc and was doing a lookup to retrieve the drm_format_info structure and return the cpp. However, this is inefficient since in most cases, we will have the drm_format_info pointer already available so we shouldn't have to perform a new lookup. Some drm_fourcc functions also already operate on the drm_format_info pointer for that reason, so the API is quite inconsistent there. Let's follow the latter pattern and remove the extra lookup while being a bit more consistent. In order to be extra consistent, also rename that function to drm_format_info_plane_cpp and to a static function in the header to match the current policy. The parameters order have also be changed to match the other functions prototype.

drm: Remove users of drm_format_(horz|vert)_chroma_subsampling

2019-05-20T11:33:11Z

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling are basically a lookup in the drm_format_info table plus an access to the hsub and vsub fields of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to these functions is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure. This is amplified by the fact that most of the time the callers will have to retrieve both the vsub and hsub fields, meaning that they would perform twice the lookup.

drm/fourcc: Add format info helpers for checking YUV sub-sampling

2019-01-18T18:00:18Z

Display engine drivers often need to distinguish between different types of YUV sub-sampling. This introduces helpers to check for common sub-sampling ratios in their commonly-used denomination from the DRM format info.
