Bug ID: 105651 Summary: Vega64 doesn't output properly onto dell up2715k at 5120x2880 Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: spgle212@gmail.com
I have tested 4.16 and drm-next-4.17 both under wayland and xorg. All only show the monitor as 2 displays with 2560x2880 side by side. (I previously had an nvidia gpu using their binary blob on this display without issue)

--- Comment #1 from Harry Wentland harry.wentland@amd.com --- amdgpu doesn't currently have support for tiled displays. It's expected with tiled displays that you see them as you describe.

--- Comment #2 from Alex Deucher alexdeucher@gmail.com --- This is handled at the Desktop level. There are quite a few large format displays that show up as multiple DP MST displays, even a number of early 4k displays. X exposes the tile info via randr 1.5 and the desktop environment should handle it as a single monitor. Mutter handles this in GNOME for example.

--- Comment #3 from spgle212@gmail.com --- Yes it is handled at Desktop level. (https://gitlab.gnome.org/GNOME/mutter/issues/110)
But the tile property has to be exposed from kernel driver as far as i understand. Which was not the case in my setup with amdgpu. With the new patch from here https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/merge_requests/... it should work but i can not see any tiled properties.

--- Comment #4 from spgle212@gmail.com --- For this to work the TILE property (blob) of the connector has to be exposed. modetest does not return it.
https://bugs.freedesktop.org/show_bug.cgi?id=105651
--- Comment #5 from spgle212@gmail.com --- xrandr --props also does not return the tile property.

--- Comment #6 from Redsandro freedesktop@redsandro.e4ward.com --- I'm having the same issue with a 4K Dell UP2414Q with 3840x2160 as 1920x2160+0+0, 1920x2160 +1920+0.
Is it possible to do a workaround in xorg.conf, similar to nVidia's TwinView and nvidiaXineramaInfoOrder as described in this question?

--- Comment #7 from Alex Deucher alexdeucher@gmail.com --- You need to be using the amdgpu driver if you are running xorg. I'm not sure if the modesetting driver supports the tile property yet.
https://bugs.freedesktop.org/show_bug.cgi?id=105651
--- Comment #8 from Tomas Bzatek bugs@bzatek.net --- FYI starting with kernel 5.2 the tile property is propagated properly on Dell UP2715K. The Mate desktop picks this up just fine.

--- Comment #9 from Redsandro freedesktop@redsandro.e4ward.com --- @AlexDeucher I am using xserver-xorg-video-amdgpu. I can use 18.0.1 (No TILE support, need workaround) or 19.0.1 (Cinnamon crashes, need workaround for time being). I'm looking for a xorg config or xrandr command that works like nVidia's TwinView that I can keep in place while I am checking TILE support with this DM and kernel from time to time. (I am new to AMD/Radeon.)
@TomasBzatek I still need a workaround because Cinnamon crashes on 5.2 w/ 19.0.1 TILE support. See https://github.com/linuxmint/cinnamon/issues/8807
