Add Dell AMD Radeon HD 7470 1GB to site
trafficstars
Today I received a Dell AMD Radeon HD 7470 1GB (C26411), which was marked on eBay as being a 'Dell Radeon HD 6450', but reports in the system as "Dell Radeon HD 7470":
The Radeon 7470 has 1GB of GDDR5 VRAM, uses the Caicos GPU ('Southern Islands'), and was launched in Jan 2012 (according to TechPowerUp. Power draw is rated at 27W maximum, which could be an issue if driving it direct off the Pi's PCIe slot without an externally-powered riser.
So far it seems the branch we're working on in #4 (mainly by @Coreforge) also works with this card out of the box. To get the card working, here's what I did on a stock Pi and Pi OS:
- Image Pi OS (the older January 2022 copy built on top of Debian 5.10.x) to your Pi.
- Compile Coreforge’s GPU branch and copy the built kernel to the Pi.
- Install AMD firmware: sudo apt install -y firmware-amd-graphics
- Set up this custom memcpy.so to be preloaded on the system.
- Reboot.
Note that work is continuing in #4 — this issue is only for documenting differences and results with the HD 7470.

I'm using the same branch from @Coreforge for 5.10.y / AMD Radeon that he's testing on the 6450 and I've also tested on my 5450.
startx results in a working display at the start, though it jumps up and down a few pixels here and there. (This is over DisplayPort to DVI on my monitor).
glxgears gives a similar style to the 5450 I've been testing, with the screen blinking on each gear turn, until Xorg eventually stops rendering. I can kill Xorg with kill -9 -1 [pid].
The fan on the 7470 can get quite loud during reboots! I'm glad it uses some sort of PWM though, to quiet down when it's initialized and idling...
GLMark2 (glmark2-drm) ran all the way through—a task I've been unable to complete on my 5450.

Over on Twitter, Juuso Haavisto asked if Vulkan is working.
I ran:
sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-tools
And after that, I can run vulkaninfo:

I should note that I ran that over SSH while the monitor was plugged into one of the Pi's own HDMI ports. So that may be looking at the Pi's VPU and not the Radeon GPU.

neither:
deviceType = PHYSICAL_DEVICE_TYPE_CPU
deviceName = llvmpipe (LLVM 11.0.1, 128 bits)
this is the software driver
Yeah, exact same output if I boot with display only attached to Radeon card (via DisplayPort in this case). Still looks like it's showing GPU only. I wonder if getting our driver patch ported to 5.15.y (right now I'm running 5.10.y) would help.
https://www.techpowerup.com/gpu-specs/radeon-hd-7470-oem.c299 The card itself doesn't support vulkan. That doesn't mean it wouldn't be possible for a driver to exist that implements at least part of the api, but I doubt vulkan will work on these older cards.
additionally I believe (don't quote me on that) radv only supports the amdgpu DRM driver, so if you get something like a hd 7750, you'll need to use the amdgpu module instead of radeon

Correct vulkan is only for the amdgpu driver supported devices!
Nice catch that you actually got a HD7470 GCN1 which can run both radeon or amdgpu opensource kernel drivers. Offcourse radeon kernel driver has been patched a lot already (5450 thread) before you got it running on the pi but did you try amdgpu already?
Just boot with kernel argument radeon.si_support=0 amdgpu.si_support=1 and make sure you have firmware in /lib/firmware/amdgpu/ and that your pi kernel has been compiled with the amdgpu module . More options like amdgpu.dc=1 for alternate method of initializing display connector output/modes or amdgpu.dpm=0 for disabling power management.
Also stumbled upon this patch for fixing graphic corruption with amdgpu on aarch64?
EDIT: By having a better look at your cards chipset it might actually be part of the Northern Island which sadly comes without the amdgpu driver support...
