Hi,
Here is v3 of TDX VM/vCPU creation series, which Rick and others from
Intel have handed off to me.
The only remaining snag could be the retry loop around some SEAMCALLS.
It's likely that it can be dropped but I have left it in place for now,
waiting for Yan's patient advice. :)
I dropped support for CET/PT in trusted domains, as well as for TDX
modules without MD_FIELD_ID_FEATURES0_TOPOLOGY_ENUM. I have also added
to the end a patch that I scavenged from the Intel tree to add support
for the misc cgroup.
All non-KVM patches have been acked, except for 07/29 ("x86/virt/tdx:
allocate tdx_sys_info in static memory").
This series is based straight off of Linux 6.14-rc3. It requires TDX
module 1.5.06 or later.
