drm/radeon: fix checking of MSAA renderbuffers on r600-r700
The MSAA checking was mostly unimplemented on r600-r700. The userspace submits GPU commands and the kernel driver computes how much memory the GPU will access and checks if it's all within buffer bounds the userspace allocated. This patch fixes the computations of the size of MSAA surfaces in memory. Signed-off-by: Marek Olšák <maraeo@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
