Mushroom is a project for securely running Linux workloads in attestable, integrity-protected environments with a minimalistic TCB. Mushroom depends on TEEs to provide integrity guarantees for data in use. It was initially developed for AMD SEV-SNP, but it recently gained support for running on Intel TDX as well. This talk will explore some of the required changes and discuss how the differences between AMD SEV-SNP and Intel TDX informed some of the design decisions.
