[Solved] AMD 6900 XT: Renderer string + Long display blank at startup

I'm testing an XFX AMD 6900 XT Merc 319 for now and noticed two minor issues:

1) Despite using linux-mainline and the latest Mesa dev build, the OpenGL renderer string still reports the AMD-internal codename instead of a friendly string like "AMD 6900 XT" (as was the case on the previous 5700XT).

$ glxinfo | grep OpenGL
OpenGL vendor string: AMD
OpenGL renderer string: AMD SIENNA_CICHLID (DRM 3.40.0, 5.11.0-rc6-1-mainline, LLVM 12.0.0)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 21.1.0-devel (git-4654650d6b)
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 21.1.0-devel (git-4654650d6b)
OpenGL shading language version string: 4.60
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 21.1.0-devel (git-4654650d6b)
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

2) My displays (27" 1440p, FreeSync via Displayport, 22" 1050p 60Hz via DVI->HDMI) blank and lose signal after login (or starting an XServer) before drawing again correctly when the desktop has loaded (using KDE Plasma with SDDM).
On my previously used AMD 5700XT, I got Plasma's loading screen before the desktop.
I can't spot anything amiss in /var/log/Xorg.0.log (pasted below with irrelevant and overly repetitive sections snipped).

I know that item 1 is clearly a bug, but I need a hint where I should file the bug report, possibly with more information if somebody can educate me where these strings are stored.

As for item 2, I need more pointers where to look next for debugging and where to file a bug report if applicable.

Re: [Solved] AMD 6900 XT: Renderer string + Long display blank at startup

hello fellow 6900 xt user! smile i have one too and when I looked into I noticed this:
https://archlinux.org/packages/core/any/hwids/

the hwid package is extremely out of date. it only has id's for hardware up to august 2020. so anything new after that won't have a proper id.

in regards to the dual monitor setup problem, i really don't know as i use a single monitor myself. the only thing i could think of is maybe its an issue with the different refresh rates. if you have freesync enabled, i do recall freesync not being able to function if one of the monitors doesn't have the same refresh rate. so maybe that's causing some quirks at boot up.

Thanks for the hint! I rebuilt the package with a quickly fixed up PKGBUILD and indeed correct vendor strings for tools like hardinfo are now provided.

But glxinfo output remains the same, so I figure this this is a Mesa issue then...?

Good point. I'm gonna try again with a single monitor.


- Edit:

Things I've tried:

- Booted with one monitor only (tested with both) --> No change
- Booted without the amdgpu.conf file from /etc/X11/xorg.conf.d --> No change
- Booted with Freesync disabled on the Display Port connected monitor --> No change

On closer observation, the blank/sleep issue happens during the boot process when a monitor would normally change from the low (fallback) resolution to its native one.
I have an itch that there may be a connection to the first issue with the renderer string...

Re: [Solved] AMD 6900 XT: Renderer string + Long display blank at startup

have you tried a different environment? like xfce or a openbox session? if you just swapped to the 6900 xt from the 5700 xt, maybe its some dot file with kde causing some funkyness. outside that, have you tried enabling early kms? i wish i could help you more sad i really don't know what could be causing that.

Re: [Solved] AMD 6900 XT: Renderer string + Long display blank at startup

Good point about the KMS! I've set "amdgpu" up for an early KMS start as per the wiki and that seemed to have solved the monitors switching off! So that's one issue off the list. Thanks!

Re: [Solved] AMD 6900 XT: Renderer string + Long display blank at startup

Thanks to some input from Mesa's DRM maintainers, I managed to produce a patch which fixes the device ID issue for me. See here: https://gitlab.freedesktop.org/mesa/drm … ote_802821

The libdrm package needs to be remade with the patch. Suggestions for edited/added PKGBUILD sections:

...
pkgrel=2
...
source=(https://dri.freedesktop.org/$pkgname/$pkgname-$pkgver.tar.xz{,.sig}
        COPYING
        https://gitlab.freedesktop.org/mesa/drm/uploads/95221f17e7ff5400c39244c7c515ca6c/navi_21+22+23_ids.patch)
...
prepare() {
    cd "$pkgname-$pkgver/data"
    patch --forward --strip=0 --input="${srcdir}/navi_21+22+23_ids.patch"
}

Don't forget to update the SHA512 sums (with "updpkgsums" or so) and you may need to add the gpg keys with "gpg --recv-keys [key]".


Marking the thread as solved.
