The page table of AMDGPU requires an alignment to CPU page so we should check ioctl parameters for it. Return -EINVAL if some parameter is unaligned to CPU page, instead of corrupt the page table sliently. Reviewed-by:

In Mesa, dev_info.gart_page_size is used for alignment and it was set to AMDGPU_GPU_PAGE_SIZE(4KB). However, the page table of AMDGPU driver requires an alignment on CPU pages. So, for non-4KB page system, gart_page_size should be max_t(u32, PAGE_SIZE, AMDGPU_GPU_PAGE_SIZE). Signed-off-by:

When encoder validation of a display mode fails, retry with less bandwidth heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups to support 4k60Hz output, which previously failed silently. On some setups, while the monitor and the gpu support display modes with pixel clocks of up to 600MHz, the link encoder might not. This prevents YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be possible. However, which color mode is used is decided before the link encoder capabilities are checked. This patch fixes the problem by retrying to find a display mode with YCbCr420 enforced and using it, if it is valid. Reviewed-by:
