Takashi Iwai 7f551b1eee drm/cirrus: Limit modes depending on bpp option ... The commit [8975626ea3: drm/cirrus: allow 32bpp framebuffers for cirrus drm] broke X modesetting driver because cirrus driver still provides the full list of modes up to 1280x1024 while the 32bpp can support only up to 800x600. We might be able to filter out the invalid modes in mode_valid callback, but unfortunately the bpp in question can't be referred there for now (let me know if there is a better way to retrieve the bpp for the probed fb). So, instead, this patch adds the bpp module option to specify the maximal bpp explicitly and limits the resolutions in get_modes depending on its value. The default value is set to 24 so that the existing stuff keeps working. If you need a new 32bpp feature, specify cirrus.bpp=32 option explicitly.
