Thank you for your reply.
Hello everybody,
I installed an AMD Radeon RX 7900 XTX today, switching from Nvidia. But
once I enable FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y to have a tty once
the driver is up, the following happens:
1) My Wayland compositor (Hyprland) takes very long to start.
2) reading from sysfs (e.g. running "cat
/sys/class/drm/card0/device/gpu_busy_percent") does not work and causes
a hang.
Once I disable FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=n, I have no issues
with the starting speed of the compositors at all and the mentioned
command works. But this leads to a black tty.
You'd normally need this enabled to get a fb display on the console, but I
don't know if this would be provided by proprietary drivers instead for your
card - see below.
I made a mistake here, sorry. The issue causing setting is
DRM_FBDEV_EMULATION=y, which on itself works with the open source
driver, but causes issues as soon as I start Hyprland.
It could be both. I don't think there's any Linux firmware released yet for
this card - but I don't follow the latest & greatest so I could be wrong.
You'd need the AMD amdgpu-pro on top of the amdgpu driver, to bring in the
proprietary OpenGL, OpenCL, Vulkan and AMF components:

The firmare seems good, since it is loaded just fine, "dmesg | grep
amdgpu | grep firmware" returns:

Also the mesa libraries work just fine, if I disable
DRM_FBDEV_EMULATION=n, I just get a black tty, but Hyprland starts and I
can play games with the expected performance.
