2020-09-23drm/doc: Document that modifiers are always required for fbDaniel Vetter1-0/+13
Even for legacy userspace, since otherwise GETFB2 is broken and if you switch between modifier-less and modifier-aware compositors, smooth transitions break. Also it's just best practice to make sure modifiers are invariant for a given drm_fb, and that a modifier-aware kms drivers only has one place to store them, ignoring any old implicit bo flags or whatever else might float around. Motivated by some irc discussion with Bas about amdgpu modifier support.

2020-09-23drm/ttm: stop dangerous caching attribute changeChristian König1-22/+0
When we swapout/in a BO we try to change the caching attributes of the pages before/after doing the copy. On x86 this is done by calling set_pages_uc(), set_memory_wc() or set_pages_wb() for not highmem pages to update the linear mapping of the page. On all other platforms we do exactly nothing. Now on x86 this is unnecessary because copy_highpage() will either create a temporary mapping of the page which is wb anyway and destroyed immediately again or use the linear mapping with the correct caching attributes. So stop this nonsense and just keep the caching as it is and return an error when a driver tries to change the caching of an already populated TT object. This is much more defensive since changing caching attributes is platform and driver specific and usually doesn't work after the page was initially allocated.
