[PATCH 0/4] TDX: Update the handling of <GetTdVmCallInfo> and implement <SetupEventNotifyInterrupt>

Posted by Xiaoyao Li 4 months, 2 weeks ago

It ends up as <GetQuote> is one of the base TDG.VP.VMCALL leaf, and it's
not enumerated via bit 0 of out R11 (the bit 0 becomes reserved).[1]

So patch 1 updates the handling of tdx_handle_get_tdvmcall_info().

Paolo,

Patch 2-4, enables <SetupEventNotifyInterrupt> in QEMU. They based on
the KVM patches you put in KVM tree master.

Xiaoyao Li (4):
  i386/tdx: Remove enumeration of GetQuote in
    tdx_handle_get_tdvmcall_info()
  update Linux headers to KVM tree master
  i386/tdx: Set value of <GetTdVmCallInfo> based on capabilities of both
    KVM and QEMU
  i386/tdx: handle TDVMCALL_SETUP_EVENT_NOTIFY_INTERRUPT
