Hi Lorenzo / All, https://github.com/hisilicon/kernel-dev/tree/doe-spdm-v1 rebased to 5.14-rc7 https://github.com/hisilicon/qemu/tree/cxl-hacks rebased to qemu/master as of earlier today. For qemu side of things you need to be running spdm_responsder_emu --trans PCI_DOE from https://github.com/DMTF/spdm-emu first (that will act as server to qemu acting as a client). Various parameters allow you to change the algorithms advertised and the kernel code should work for all the ones CMA mandates (but nothing beyond that for now). For the cxl device the snippet of qemu commandline needed is: -device cxl-type3,bus=root_port13,memdev=cxl-mem1,lsa=cxl-mem1, id=cxl-pmem0,size=2G,spdm=true Otherwise much the same as https://people.kernel.org/jic23/ Build at least the cxl_pci driver as a module as we need to poke the certificate into the keychain before that (find the cert in spdm_emu tree). Instructions to do that with keyctl and evmctl are in the cover letter of the patch series. Hopefully I'll find some time next week to put together some proper instructions and email them in reply to the original posting.

Maybe it is best to reschedule it early September since it is holiday season. I could do September 1st and 2nd and the following week. Please let me know what you think.

Hi Jammy, I'll be away until the 26th, but obviously that should be no barrier to topics I am less involved with as I can easily catch up later.
