2019-05-20drm: Remove users of drm_format_(horz|vert)_chroma_subsamplingMaxime Ripard
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.

2017-02-28drm/atmel-hlcdc: Simplify the HLCDC layer logicBoris Brezillon
An HLCDC layers in Atmel's nomenclature is either a DRM plane or a 'Post Processing Layer' which can be used to output the results of the HLCDC composition in a memory buffer. atmel_hlcdc_layer.c was designed to be generic enough to be re-usable in both cases, but we're not exposing the post-processing layer yet, and even if we were, I'm not sure the code would provide the necessary tools to manipulate this kind of layer. Moreover, the code in atmel_hlcdc_{plane,layer}.c was designed before the atomic modesetting API, and was trying solve the check-setting/commit-if-ok/rollback-otherwise problem, which is now entirely solved by the existing core infrastructure. And finally, the code in atmel_hlcdc_layer.c is over-complicated compared to what we really need. This rework is a good excuse to simplify it. Note that this rework solves an existing resource leak (leading to a -EBUSY error) which I failed to clearly identify.

Despite the documentation claim that cleanup_fb will match prior calls to prepare_fb, in case of NULL framebuffers in the transitional helpers, the code will skip the call to prepare_fb but not the corresponding cleanup_fb call. This asymmetry in semantics is unnecessarily surprising for developers transitioning drivers to atomic model, specially because the final atomic handlers don't have the issue - the prepare_fb is always called, despite the new state framebuffer being null. The only current user of the transitional helper that doesn't take care of null framebuffers explicitly inside the prepare_fb hook is atmel_hlcdc, so we take special care to make sure we don't break anything there.

2015-02-22drm: atmel-hlcdc: add discard area supportBoris Brezillon
The HLCDC IP provides a way to discard a specific area on the primary plane (in case at least one of the overlay is activated and alpha blending is disabled). Doing this will reduce the amount of data to transfer from the main memory to the Display Controller, and thus alleviate the load on the memory bus (since this link is quite limited on such hardware, this kind of optimization is really important).
