 Posted: Mon Dec 26, 2016 5:27 pm Post subject: What firmware files are required by amdgpu? |
 |
|
I use the amgpu driver. Unfortunately, if the driver fails to load the required firmware the kernel silently hangs and does not print any error message what file is missing. If I create an initial ramdisk that includes the whole directory structure below /lib/firmware, then everything works but the ramdisk is huge. | Code: |
genkernel --kernel-config=linux/.config --ramdisk-modules --plymouth-theme=breeze --firmware --firmware-dir=/lib/firmware initramfs
|
I failed to include only the firmware files that are actually required. On a first shot I tried | Code: |
genkernel --kernel-config=linux/.config --ramdisk-modules --plymouth-theme=breeze --firmware --firmware-files=/lib/firmware/amdgpu/tonga_mec2.bin,/lib/firmware/amdgpu/tonga_me.bin,/lib/firmware/amdgpu/tonga_pfp.bin,/lib/firmware/amdgpu/tonga_smc.bin,/lib/firmware/amdgpu/tonga_sdma.bin,/lib/firmware/amdgpu/tonga_ce.bin,/lib/firmware/amdgpu/tonga_vce.bin,/lib/firmware/amdgpu/tonga_sdma1.bin,/lib/firmware/amdgpu/tonga_rlc.bin,/lib/firmware/amdgpu/tonga_uvd.bin,/lib/firmware/amdgpu/tonga_mec.bin,/lib/firmware/amdgpu/tonga_mc.bin initramfs

, because I know I have a card from the Tonga family (PowerColor Radeon R9 380), but this is apparently not sufficient. Any idea what I am missing? |

| R9 380 is the newer revision of Tonga, it requires the tonga_k_smc.bin firmware for kernel 4.8 and newer. |

@snkmoorthy: As I have already written: | Quote: | | the kernel silently hangs and does not print any error message what file is missing |
This also impies, there is no firmware error.
@chithanh: If the R9 380 requires tonga_k_smc.bin, why does it work then if I include the whole /lib/firmware directory into the initramfs or if I compile amdgpu as a module so it it loads after /lib/firmware becomes available? tonga_k_smc.bin does not exists on my machine. |
