I sent more igt-gpu-tools test [2] to cover more things and detect the issues in [1]. This patchset is based on [1]. Patch 1/2: This patch is a no-op, but make the code more readable regarding the pixel_read functions. Patch 2/2: This patch is more complex. My main target was to solve issues I found in [1], but as it was very complex to do it "in place", I choose to rework the composition function. The main two advantages are: - It's now possible to create conversion function for packed & grouped pixels. Some pixel formats need absolute x/y position and not only an offset in the buffer to extract the correct value. This part also solve the issues I found in [1]. - The rotation management is now way easier to understand, there is no more switch case in different places and instead of copy/pasting rotation formula I used drm_rect_* helpers.
