With modifiers one can actually have different format_info structs
for the same format, which now matters for AMDGPU since we convert
implicit modifiers to explicit modifiers with multiple planes.
I checked other drivers and it doesn't look like they end up triggering
this case so I think this is

is my alternative patch.

I think the problem here is that application A can set the FB and then
application B can use getfb2 (say ffmpeg).

This is a slight improvement for legacy flipping, but also an attempted
fix for a bug/regression introduced into Linux 4.11-rc.
Commit 816853f9dc4057b6c7ee3c45ca9bd5905 ("drm/amd/display: Set new
format info for converted metadata.") fixes the getfb2 ioctl, but
in exchange it completely breaks all

Yes. That, and also the check for 'X' won't get us far, because if i

hello, I'd like to report this issue that I am having since I updated my
display (samsung U28E590). The amdgpu does not support the native
resolution of my new monitor, which is 3840x2160*.* Using a HDMI or DVI
connection (I tried both, same results), the maximum supported refresh is
30Hz, so I'm s
