SVSM Development Call April 2nd, 2025

Hi,

Here is the usual call for agenda items for the this weeks SVSM development call. Please send me any agenda items you have in mind or raise them in the meeting.

Europe switched to summer time as well, so meeting time is back to normal for all US participants.

Details of the meeting (GMeet and Calendar links, meeting time) can be found in our governance repository at:

https://github.com/coconut-svsm/governance

The meeting will be recorded and the recording eventually published.

See you all there.

Regards,

Jörg

I would like to get a clear go/no-go for the proposed SVSM_ATTEST_SINGLE_SERVICE_EX addition to the SVSM specification so we can get the ABI committed for Linux to accept the corresponding additional WO binary attribute for manifest_selector.

I have patches staged on Linux v6.15-rc7 that I won't post on LKML until there's agreement of the specification change:

For SVSM_ATTEST_PROTOCOL support, we need to first merge the same memory read/write from/to guest memory
https://github.com/coconut-svsm/svsm/pull/653
Then we can talk about SVSM_ATTEST_SINGLE_SERVICE_EX in
https://github.com/coconut-svsm/svsm/pull/662
