This series is based on v6.10-rc1. I also successfully cherry-picked the patches onto v6.10-rc6 and linux-next 20240628 (no merge conflicts and no issues reported by 0-day). Older kernels than v6.10-rc1 won't work because they're missing ecdsa-nist-p521 support as well as a few preparatory sysfs patches of mine that went into v6.10-rc1. > I am using https://github.com/l1k/linux.git branch cma_v2 for now but wonder > if that's the right one. Yes that's fine. There's now also a kernel.org repository with a testing branch: https://git.kernel.org/pub/scm/linux/kernel/git/devsec/spdm.git/ Future maintenance of the SPDM library is intended to be happening in that repo. I assumed that Bjorn may not be keen on having to deal with SPDM patches forever, so creating a dedicated repo seemed to make sense. Most patches in this series with a "PCI/CMA: " subject actually only change very few lines in the PCI core. The bulk of the changes is in the SPDM library instead. I used that subject merely to highlight that at least an ack from Bjorn is required. The only patches containing PCI core changes to speak of are patches 8, 9, 10. The devsec group (short for Device Security Alphabet Soup) currently only contains the spdm.git repo. Going forward, further repos may be added below the devsec umbrella, such as tsm.git to deal with a vendor-neutral interface between kernel and Trusted Security Module. Thanks, Lukas
