go-configfs-tsm
Golang interface to Linux's TSM configfs subsystem
I’m the primary author of the go-configfs-tsm project. This is meant to be a thin wrapper around the already pretty simple configfs interface, but just to make Golang uses of it easier.
Main features
The TSM report system is the only real subsystem that is merged. It has several attributes for interacting with AMD SEV-SNP and the SVSM. The RTMR subsystem that the Intel crowd has been trying to get upstream has a provisional interface in the library. We have support just for the initial patchset from the mailing list. The new set being discussed 2025 February/March is not yet part of it.
Influence and application
This library is meant to be the unifying client library between go-tdx-guest, go-sev-guest, and eventually the expected way to get ARM CCA attestations. Apparently the ARM and Linaro folks have used it during their own testing.
