DRM/AMDGPU logs (journalctl)

I have a Radeon RX Vega 56 connected to a Sony 4K TV (kd-49x8305c) via a "Premium" (certified) HDMI 2.0 cable. The TV's HDMI input is set to "Enhanced Format". Thus, on the hardware side, everything's ready to go for 4k@60Hz. On the software side, I'm running Arch Linux with mesa-git (rev. 066d1dc951), llvm-svn (rev. 313470), and Linux branch amd-staging-drm-next (4.13 rev. dcae401d1113).  I'm running Gnome and I've tested both Wayland and Xorg.

While other functionality such as rendering and acceleration work with this setup, I have been unable to access any 4k resolutions.

As you'll see in the attached logs, the maximum resolution detected from the TV's EDID is 1920x1080. However, using the program edid-decode (output attached), one can see that the EDID clearly advertises 4k modes, however, they're in the Extension block at VIC indexes higher than 64.

Until recently, 64 was the highest supported by drivers/gpu/drm/drm_edid.c in the kernel.  However, that has been fixed:

https://github.com/torvalds/linux/commit/8ec6e0755565192b328059b64f982adabbecda78#diff-f1b0089a97dd0195eb24305ab63a79e3

That commit has been merged into the amd-staging-drm-next kernel (but not amd-staging), and the revision that I have built and installed includes that code.  Nevertheless, I haven't had any luck in getting the computer to recognize any of those extended modes.

I have tried adding the mode manually via xrandr, however when I try to switch to that mode, I get the error "xrandr: Configure crtc 0 failed". Trying to set it in a conf file in /etc/X11/xorg.conf.d also didn't work (I no longer have a configuration file in there). I've also tried forcing it from the kernel command line (video=3840x2160@60) to no avail.  Still, all of those seem like workarounds when I think the problem is pretty clearly that the VIC 65+ modes are not detected.

Comment 3 invergo 2017-11-16 21:35:31 UTC

I'm now on drm-next-amd-dc-staging commit 4479ed411cf4. I can see in my logs that all of the modes in my TV's EDID are being detected.  GDM launches at 1920x1080 as usual, but when I try to log in, all video output is lost (TV reports no input) and the computer freezes, requiring a hard reboot.  If I first switch to a virtual console and restart GDM, I'm able to log into a 1920x1080 Gnome desktop. Under the Displays settings, all of my TV's supported resolutions are listed.  However, when I switch to a 4k resolution, the system crashes again and the video output is lost.

Checking my logs, I see the following errors:

Sorry, I should have attached that in a file.

Just before those kernel errors were these:

I'm not sure if the first two gnome-shell errors are relevant.
The latter two kernel messages I guess reflect the attempt to change resolutions to 3840x2160, but then is it trying to revert back to 1920x1080 albeit at 15Khz?

I am on commit 23d3505d648e and this now appears to be resolved: I can select 4k@60Hz (among several other new resolutions) without crashing. Furthermore, this also resolves a problem I hadn't mentioned of not having HDMI audio (didn't realize that it could be related).

Resolving per comment 5, thanks for the followup, glad it's working now!
