I have an RX 580 (Polaris 10 GPU) that I am using with my Gentoo system. I build my own kernel, which is completely typical with Gentoo. I'm not using any initramfs, but the kernel loads the amdgpu module during the boot process.

The AMDGPU driver doesn't appear to be loading any firmware. I've built the kernel with the following options:

CONFIG_DRM_AMDGPU=m

CONFIG_DRM_AMDGPU_SI=y

CONFIG_DRM_AMDGPU_CIK=y

CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

CONFIG_EXTRA_FIRMWARE="intel-ucode/06-2d-07 radeon/tahiti_ce.bin radeon/tahiti_mc.bin radeon/tahiti_me.bin radeon/tahiti_pfp.bin radeon/tahiti_rlc.bin radeon/tahiti_smc.bin radeon/TAHITI_uvd.bin amdgpu/polaris10_ce.bin amdgpu/polaris10_ce_2.bin amdgpu/polaris10_k_smc.bin amdgpu/polaris10_k2_smc.bin amdgpu/polaris10_k_mc.bin amdgpu/polaris10_mc.bin amdgpu/polaris10_me.bin amdgpu/polaris10_me_2.bin amdgpu/polaris10_mec2.bin amdgpu/polaris10_mec2_2.bin amdgpu/polaris10_mec.bin amdgpu/polaris10_mec_2.bin amdgpu/polaris10_pfp.bin amdgpu/polaris10_pfp_2.bin amdgpu/polaris10_rlc.bin amdgpu/polaris10_sdma1.bin amdgpu/polaris10_sdma.bin amdgpu/polaris10_smc.bin amdgpu/polaris10_smc_sk.bin amdgpu/polaris10_uvd.bin amdgpu/polaris10_vce.bin"

The firmware config also includes the firmware for my CPU, which loads fine, as well as my old Tahiti-based GPU. I have verified that all the Polaris firmware specified is in the /lib/firmware/amdgpu directory, and that all the Polaris firmware in that directory is listed in the kernel config.

But I'm not seeing any messages in dmesg that either the firmware loaded, or failed to load. Looking around I seem to find examples where firmware is supposed to have loading messages and I don't have those, e.g.:

[    3.603145] amdgpu 0000:01:00.0: firmware: direct-loading firmware amdgpu/polaris10_pfp.bin

[    3.603623] amdgpu 0000:01:00.0: firmware: direct-loading firmware amdgpu/polaris10_me.bin

But I don't have such messages, at least for the GPU. (The CPU microcode is loading fine).

For the curious, the root of the issue is that the card has the reset bug with VFIO. The RX 580 is known to be finicky with this, but I'm hoping that getting the updated firmware might help. The card works well enough for displaying things in Linux, so I know basic driver functionality is fine.

'modinfo -F firmware amdgpu' produces an enormous amount of output, including all 21 firmware blobs for polaris10 and a few hundred other blobs as well, for apparently every GPU supported by the amdgpu driver.

Following is the output of "dmesg | grep -e amdgpu -e drm"
