I think you selected the wrong type. What happens if someone sets this

This patchset is the second version of [1]. It is almost a complete
rewrite to use a line-by-line algorithm for the composition.
During the development of this series Pekka and Arthur found an issue in
drm core. The YUV part of this series depend on the fix [9]. I'll let

Introduce two typedefs: pixel_read_t and pixel_write_t. It allows the
compiler to check if the passed functions take the correct arguments.
Such typedefs will help ensuring consistency across the code base in
case of update of these prototypes.

Introduce the usage of block_h/block_w to compute the offset and the
pointer of a pixel. The previous implementation was specialized for
planes with block_h == block_w == 1. To avoid confusion and allow easier
implementation of tiled formats. It also remove the usage of the
deprecated format field
As the pixel_read and pixel_write function should never modify the input
buffer, mark those pointers const.

As all the rotation are now supported by VKMS, this simplification does

This allows more performance by not requiring an indirection per pixel
