As I known, AMDVLK is running on amdgpu driver, not support readon kernel driver.

It throws a VK_ERROR_OUT_OF_HOST_MEMORY. This appears to be due to an outdated firmware, as replacing the firmware with the firmware provided by the amdgpu-pro driver fixes the issue ( https://github.com/GPUOpen-Drivers/AMDVLK/issues/17). The issue appears to also be present on pitcairn cards.
