Pekka Paalanen 6502735f01 cogl: Remove mesa_46631_slow_read_pixels_workaround ... This function gets hit even today on relatively modern Intel systems (I have a Haswell Desktop with Mesa 18.2.4) if the pixel format is right. Presumably it makes things slower for no longer a reason. According to cb146dc515, this functionality was refactored into a workaround path in 2012. The commit message mentions the problem existing before Mesa 8.0.2. The number refers to https://bugs.freedesktop.org/show_bug.cgi?id=46631 . The use case where I hit this is when improving support for DisplayLink video outputs. These are used through a "secondary GPU", and since DisplayLink does not have a GPU, Mutter uses the CPU copy path with Cogl read-pixels[1]. If the DisplayLink framebuffer was allocated as DRM_FORMAT_XRGB8888 (the only format it currently handles correctly), mesa_46631_slow_read_pixels_workaround would get hit. The render buffer is the same format as the framebuffer, yet doing the copy XRGB -> XRGB ends up being slower than XRGB -> XBGR which makes no sense. This patch is not sufficient to fix the XRGB -> XRGB copy performance, but it is required. This patch reverts CoglGpuInfoDriverBug into what it was before cb146dc515. [1] This is not actually true until https://gitlab.gnome.org/GNOME/mutter/merge_requests/278 is merged. https://gitlab.gnome.org/GNOME/mutter/merge_requests/313		2018-12-19 19:21:51 +00:00
