Test AMD RX 9070 XT 16GB

[geerlingguy]

I just bought a PowerColor AMD RX 9070 XT Reaper, with 16GB of GDDR6 RAM.

I am testing it with yanghaku's 15 line DRM patch to see if it works 'out of the box' as the other AMD GPUs have—it may need some updated firmware that's not already in the firmware-amd-graphics package on Debian.

Current steps to get this card working with Pi OS Bookworm

Last updated: 2025-10-01

1. Clone the Raspberry Pi Linux kernel patching the default Raspberry Pi rpi-6.17.y kernel tree with this patch.
2. Before compiling the kernel, run make menuconfig and select the options:
   1. Kernel Features > Page Size > 4 KB (for Box86 compatibility)
   2. Device Drivers > Graphics support > AMD GPU (optionally SI/CIK support too)
3. Recompile the kernel following Raspberry Pi's instructions
4. Install the AMD firmware: sudo apt install -y firmware-amd-graphics
5. Install additional firmware for this card (see 'Install Additional Firmware')
6. ONLY if running Bookworm (Pi OS 12): Update Mesa to the latest version (version 25+)
7. Reboot the Pi with the card attached using an appropriate PCIe riser and external ATX power supply.

Confirm everything's working

Confirm everything is working by plugging a monitor into the graphics card; then confirm the card's GPU is in use by running glxinfo -B (part of the mesa-utils package), for example:

$ DISPLAY=:0 glxinfo -B
name of display: :0
display: :0  screen: 0
direct rendering: Yes
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: AMD (0x1002)
    Device: AMD Radeon Graphics (radeonsi, gfx1201, ACO, DRM 3.63, 6.15.11-v8-4k-gpu+) (0x7550)
    Version: 25.0.7
    Accelerated: yes
    Video memory: 16384MB

I wonder if the blank screen is because I had built both radeon and amdgpu into my latest kernel build, for testing older AMD cards? I've re-built the kernel again without it enabled (also removing nouveau) to see if there's some issue there.

[geerlingguy]

Ah, looking more closely, there is a blinking cursor up in the top left. So... maybe I need to disable the built-in iGPU like on Intel Arc cards? Testing that now, by editing /boot/firmware/config.txt and commenting dtoverlay=vc4-kms-v3d, then rebooting.

That didn't help, though. Still the blinking cursor on the blank screen. Also tried a DisplayPort output into my monitor instead of HDMI. Exact same thing.

If I hit Alt + F2 I get to text mode and can log in.

Then startx, and it starts the GUI. Why is it not doing it automatically??? (That works but is not the labwc environment.)

When I try running labwc, I get:

Mesa version default in Bookworm:

$ vulkaninfo | grep "Mesa"
'DISPLAY' environment variable not set... skipping surface info
VK_LAYER_MESA_overlay (Mesa Overlay layer) Vulkan version 1.3.211, layer version 1:
	driverInfo      = Mesa 24.2.8-1~bpo12+rpt4
	driverInfo                                           = Mesa 24.2.8-1~bpo12+rpt4
	driverInfo      = Mesa 24.2.8-1~bpo12+rpt4 (LLVM 15.0.6)
	driverInfo                                           = Mesa 24.2.8-1~bpo12+rpt4 (LLVM 15.0.6)

I'm upgrading Mesa, to see if that helps.

Add the following lines inside /etc/apt/sources.list:

deb https://deb.debian.org/debian/ bookworm-backports main contrib non-free
deb-src https://deb.debian.org/debian/ bookworm-backports main contrib non-free

Run sudo apt update, then install the updated mesa version:

sudo apt install -t bookworm-backports mesa-vulkan-drivers

After a reboot, the new Mesa version is:

$ vulkaninfo | grep "Mesa"
VK_LAYER_MESA_overlay (Mesa Overlay layer) Vulkan version 1.4.303, layer version 1:
	driverInfo      = Mesa 25.0.7-2~bpo12+1
	driverInfo                                           = Mesa 25.0.7-2~bpo12+1
	driverInfo      = Mesa 25.0.7-2~bpo12+1 (LLVM 15.0.6)
	driverInfo                                           = Mesa 25.0.7-2~bpo12+1 (LLVM 15.0.6)

And what's better... it works!

[geerlingguy]

Running glmark2-es2-wayland gives tons of errors like:

[effect2d] kernel=1,1,1,1,1;1,1,1,1,1;1,1,1,1,1;:'gfx1201' is not a recognized processor for this target (ignoring processor)
'gfx1201' is not a recognized processor for this target (ignoring processor)
amd: LLVM doesn't support gfx1201, bailing out...
 FPS: 10299 FrameTime: 0.097 ms

But it does run.

[geerlingguy]

Total system power draw while running GravityMark is around 266W, not bad (idle power around 15W, also pretty good compared to many other older graphics cards I've tested):

Result:

[geerlingguy]

Re-testing on kernel rpi-6.17.y with the nightly Debian Trixie image, I got everything going pretty quickly.

I also did not need to install a later version of Mesa, so I'm going to update the instructions in the top post to note that change.

$ DISPLAY=:0 glxinfo -B
name of display: :0
display: :0  screen: 0
direct rendering: Yes
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: AMD (0x1002)
    Device: AMD Radeon Graphics (radeonsi, gfx1201, ACO, DRM 3.64, 6.17.0-v8-4k-gpu+) (0x7550)
    Version: 25.0.7
    Accelerated: yes
    Video memory: 16384MB
    Unified memory: no

What's odd is I only got a score of 41,193 (re-tested 3x) with this Trixie setup, compared to 56,944 under Bookworm with Mesa compiled from source. That seems like a pretty hefty performance delta!
