Hi Mimi, > Instead of emitting the per TPM PCR bank "boot_aggregate" values one > at a time, store them in a buffer and emit them all at once. Thanks for notifying me. I see you already pushed this commit into next-testing and I found few problems, thus posted patches to ML: segfault bug on system with TPM 1.2 only [1], running tsspcrread on system without TPM [2] and logging problem [3]. I'll move the discussion there. Kind regards, Petr [1] https://patchwork.kernel.org/patch/11612893/ [2] https://patchwork.kernel.org/patch/11612911/ [3] https://patchwork.kernel.org/patch/11612913/
