[ Reason ] I would like to bring the *firmware* update level for AMD processors in Bullseye and Bookworm to match what we have in Sid and Trixie. This is the bug report for Bullseye, a separate one will be filled for Bookworm. The update is a security update for AMD-SEV (AMD-SB-3003). It does not change the processor microcode. [ Impact ] These updates fix security issues on AMD SEV. [ Tests ] The package was tested, but AMD-SEV was not specifically tested. I could not find any reports of AMD-SEV issues due to this firmware update though. This update only changed a few docs and the binary blob files, so it is as safe as what is already accepted for bullseye and bookworm. [ Risks ] AMD-SEV changes cannot cause boot regressions, but it could cause SEV functionality regressions. I am not aware of any regressions related to this SEV firmware update. [ Checklist ] [x] *all* changes are documented in the d/changelog [x] I reviewed all changes and I approve them [x] attach debdiff against the package in (old)stable [x] the issue is verified as fixed in unstable [ Changes ] * Documentation was updated with upstream information * Binary microcode blobs were updated with new upstream binary blobs. [ Extra Information ] Diff was generated from the git tree, in order to avoid excessive noise due to the changes to the binary blobs. diffstat: README | 20 ++++++++++++++++++++ amd/amd_sev_fam17h_model3xh.sbin |binary amd/amd_sev_fam19h_model0xh.sbin |binary amd/amd_sev_fam19h_model1xh.sbin |binary amd/amd_sev_fam19h_modelaxh.sbin |binary debian/changelog | 30 ++++++++++++++++++++++++++++++ 6 files changed, 50 insertions(+) -- Henrique Holschuh
