Package: amd64-microcode Version: 3.20230719.1~deb12u1 Severity: normal X-Debbugs-Cc: ma...@karppinen.fi
Dear Maintainer, For a few years now I've noticed errors like this in dmesg output: > ccp 0000:43:00.1: firmware: failed to load amd/amd_sev_fam17h_model31h.sbin > (-2) > firmware_class: See https://wiki.debian.org/Firmware for information about > missing firmware > ccp 0000:43:00.1: firmware: failed to load amd/amd_sev_fam17h_model31h.sbin > (-2) Today I finally decided to look into this. It looks like amd64-microcode installs the appropriate firmware for my system in /lib/firmware/amd/amd_sev_fam17h_model3xh.sbin but the system does not understand it applies. The linux-firmware.git commit message[1] says: > SEV firmware files are to be placed in the "amd" directory and names > should follow the pattern: amd_sev_fam<FAMILY>h_model<MODEL>h.sbin > > where FAMILY is the two-digit hexadecimal value of the target processor > family (e.g. 17) > > where MODEL is the two-digit hexadecimal value of the target processor > model (e.g. 01) or where the least significant nibble of the two-digit > hexadecimal value can be an 'x' to indicate a range of models > (e.g. 0x for 00 to of). Armed with this information, I symlinked amd_sev_fam17h_model31h.sbin to amd_sev_fam17h_model3xh.sbin and it now loads up fine: > ccp 0000:43:00.1: firmware: direct-loading firmware > amd/amd_sev_fam17h_model31h.sbin > ccp 0000:43:00.1: SEV API:0.24 build:16 As a fix for this issue, would it make sense for amd64-microcode to include symlinks for all of the possible model numbers (0-f for each 'x' in the file name)? Thank you!
