Hi Tianyu,
This patchset is to add AMD sev-snp enlightened guest support on hyperv. Hyperv uses Linux direct boot mode to boot up Linux kernel and so it needs to pvalidate system memory by itself. In hyperv case, there is no boot loader and so cc blob is prepared by hypervisor. In this series, hypervisor set the cc blob address directly into boot parameter of Linux kernel. If the magic number on cc blob address is valid, kernel will read cc blob. Shared memory between guests and hypervisor should be decrypted and zero memory after decrypt memory. The data in the target address. It maybe smearedto avoid smearing data. Introduce #HV exception support in AMD sev snp code and #HV handler.
I am interested to test the Linux guest #HV exception handling (patches 12-16 in this series) for the restricted interrupt injection with the Linux/KVM host.
Do you have a git tree which or any base commit on which I can use to apply these patches? Thank You, Pankaj
