Hi Klaus,
CONFIG_EXTRA_FIRMWARE="amd-ucode/microcode_amd_fam19h.bin
amdgpu/psp_13_0_5_toc.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
[...]
What firmware blobs of linux-firmware has to be installed to support
the gpu of a ryzen-7900X?
CONFIG_EXTRA_FIRMWARE=?
I do not use initrd nor initramfs and all neccessary drivers
are not installed as modules but compiled into the kernel.
like you, I also use amdgpu hardcompiled into the kernel. It seems to be
safe to include _all_ blobs in /lib/firmware/amdgpu. Then you can boot
that kernel and check which blobs are actually necessary just by
grepping though dmesg. Then you can boil down CONFIG_EXTRA_FIRMWARE to
that set.
This worked with several different AMD GPUs, RX 7900 included, but I
never tried an integrated GPU/APU.
Cheers
Björn
