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?
Never mind. I could apply the patches 12-16 on master (except minor
tweak in patch 14). Now, will try to test.
Thanks,
Pankaj
