Compatibility rules

In general, any PCIe device will work providing that an open source driver is available for your operating system. There are some exceptions:

  • Hardware bugs. POWER does not permit errant DMA accesses. If a device tries to access areas of host memory which it is not permitted to access, the device is shut down immediately. This is dissimilar to x86 platforms, which simply silently ignore such attempts. Some badly designed I/O devices have bugs causing them to attempt DMA accesses to random areas of host memory; these devices are unlikely to function correctly on POWER systems unless a workaround is available. Note that devices in full bypass mode may legally have access to all host memory, to avoid this and test driver IOMMU setup pass "iommu=nobypass" to the kernel at startup.
  • I/O space. Starting with POWER9, access to the legacy PCI I/O space is no longer supported; devices or drivers which rely on this will not function. The legacy I/O space has been deprecated for as long as PCIe has existed; generally this will only affect very old PCIe devices which use PCIe to PCI bridge chips to attach old PCI devices to the bus. A small subset of these devices may require legacy I/O space support.
  • Incomplete memory addressing support. The PCIe architecture specifies a 64-bit address space. Some I/O devices try to economize on this by only implementing e.g. 40 bits for their addressing, rendering them incapable of addressing host memory which lies above address 240. (Firmware patches to work around this are pending.)
  • Bifurcation limits. Arbitrary PCIe lane bifurcation is not supported. Devices which split a PCIe slot into multiple connectors (for example, PCIe to M.2 adaptors) will not work unless they have a PCIe switch chip, although the first connector will generally work.


If a PCIe device is in a broken state due to being attached/detached from a VM, or due to a transition from Petitboot to the main OS, you may be able to fix it by issuing a hot reset. A script for performing a PCIe hot reset is at File:Pcie hot reset.sh. For background on PCIe resets and how a hot reset differs from the function-level reset performed by echo 1 > /sys/bus/pci/devices/$dev/reset, see Alex Forencich's explanation on Stack Exchange.

All AMD GPUs currently have DMA issues (limited to 32-bit, which can cause crashes) due to missing Linux kernel support for DMA windows between 33 and 63 bits in length. The root cause is GPU vendors (and occasionally some non-GPU vendors) cutting costs and only including 40-bit capable (Intel-style) DMA controllers. A compatibility mode is expected to be included in Linux 5.4 and above that will resolve this issue.

  • AMD Radeon HD 5570 - Archaic (1GB VRAM, PCI 2.1) but much faster than the AST. This card (ASUS EAH5570 Silent) is passively cooled.
  • AMD Radeon HD 5850 - Must disable onboard VGA first. Currently has issues with only using 32-bit DMA.
  • AMD Radeon HD 6450 - Works with default settings (kernel: radeon, X: modesetting or radeon), tested in BE mode
  • AMD Radeon HD 6850 - Disable AST VGA with jumper. 32 bit.
  • AMD Radeon HD 7850 - Disabled onboard VGA. Using amdgpu is highly unstable, radeon driver is usable but has issues with only using 32-bit DMA.
  • AMD Radeon HD 7950 - Must disable onboard VGA first. Currently has issues with only using 32-bit DMA.
  • AMD Radeon R5 220
  • AMD Radeon R5 230 - Works in BE mode (use Option "AccelMethod" "EXA" for Xorg)
  • AMD Radeon R7 240
  • AMD Radeon R9 290X
  • AMD Radeon R9 Nano - Must disable onboard VGA first. Works perfectly under Linux 5.6.x (ppc64le 64K page size) on Fedora 32. There is no video output on kernel 5.7.x (ppc64le 64K page size) to workaround this issue the kernel parameter `amdgpu.dc=0` must be added into grub config. The driver has been regressed since 5.8.x (ppc64le 64K page size) and thus will crash randomly. The only workaround is to re-compile the kernel to use 4K page size.
  • Sapphire GPRO 8200 (Polaris10 core) - Disable AST VGA with jumper, disabling in grub is not enough. Same form factor as WX7100, a single-slot RX 470 with 8GB of RAM and 4 DP outputs.
  • AMD Radeon RX 480
  • AMD Radeon RX 550 - Works with caveats (below) for particular card tested.
    • Card tested was Gigabyte GV-RX550D5-2GD in a Blackbird with Ubuntu 19.10, 5.3.0-24 and amdgpu with onboard VGA disabled by jumper. Suspect with tweaking would work without needing to disable VGA. Alas would lock up every day or two, to the point I replaced with a Sapphire RX580. Based on conversations w/Raptor suspect this was an issue with the model card I had rather than the RX550 itself.
  • AMD Radeon RX 560X
  • AMD Radeon RX 580 – Works with the amdgpu firmware from Ubuntu 19.04 and disabled onboard VGA
    • You may also need a kernel parameter like vga=797 if xinit complains about VESA[3]
    • The Sapphire NITRO+ Radeon RX 580 8GB card is a tight fit on the Blackbird planar if you're using the 2nd PCIe slot as it a bit wider than two slots (and is documented as such). Solved by removing the adapter plate for the PCIe-M2 adapter card being used and allowing it to sit in slot untethered.
  • AMD Radeon RX Vega 56 - Works with Debian Buster with amdgpu. Requires patches to work, somewhat unstable but usable. Cannot use AST Integrated VGA and AMDGPU at the same time without causing conflict. Not tested at this moment for use in petitboot or firmware.
  • AMD Radeon RX Vega 64 - Works with Fedora 32 with Linux kernel 5.5.0's amdgpu. The card does _NOT_ display in bootloader because vega10 firmwares failed to load correctly.
  • AMD Radeon Pro WX4100 (Polaris11 core) - May need at least linux 4.16 in order to get Xorg to work.
  • AMD Radeon Pro WX5100
  • AMD Radeon Pro WX7100 (Polaris10 core) - Available pre-installed on Talos II workstation, server, and desktop configurations.
  • AMD Radeon RX 5700 (Navi 10) - Requires kernel patches to enable display output.
  • AMD Radeon RX 5700 XT (Navi 10) - Requires kernel patches to enable display output.

The core name is important when storing the firmware into the BOOTKERNFW partition in PNOR for use by skiroot.


  • NVIDIA Corporation G96 [GeForce 9500 GT] (rev a1) - Works in petitboot if onboard VGA is disabled. Currently has issues with only using 32-bit DMA. No firmware needed.
  • NVIDIA RTX 2070 - usable for compute, but not 3D acceleration; integrated by Raptor as part of the Talos II PowerAI Development System configuration


  • ASPEED AST2500. Works in both the main OS (LE mode) and Petitboot. BE mode partially works (doesn't crash, but colors are wrong unless you apply a patch that is harmful to performance). ast Linux driver.
  • ClimaxDigital CUH195 USB 2.0 Graphic Adapter - Based on DisplayLink DL-3500 chipset. Works in the main OS; not tested with Petitboot but is likely to work there too.
  • EVGA 100-U2-UV12-A1 UV Plus USB VGA Adapter - DisplayLink Based - Petitboot shows up without loading firmware. Not tested in OS.
