This patch series is to enable TDX support.
This needs corresponding KVM patch for TDX[] and more patches are needed
that addresses generic corner cases, e.g. ACPI related stuff, are needed.
So This patch series is RFC.
More emulated devices and their behavior needs to be adjusted as some
operations are disallowed.
Patch series is organized as follows
1- 5 code refactoring and simple hooks that will be used later
6- 9 introduce kvm type and tdx type. disallow non-usable operations
10-15 wire up necessary TDX kvm ioctl to initialize TD guest
16-21 load TDVF and setup necessary info for TDVF
22-23 force x2apic and disable PIC
Isaku Yamahata (12):
kvm: Switch KVM_CAP_READONLY_MEM to a per-VM ioctl()
KVM: i386: use VM capability check for KVM_CAP_X86_SMM
vl: Introduce machine_init_done_late notifier
i386/kvm: Skip KVM_X86_SETUP_MCE for TDX guests
target/i386: kvm: don't synchronize guest tsc for TD guest
i386/tdx: Frame in the call for KVM_TDX_INIT_VCPU
hw/i386: Add definitions from UEFI spec for volumes, resources, etc...
i386/tdx: Add definitions for TDVF metadata
i386/tdx: Parse tdvf metadata and store the result into TdxGuest
i386/tdx: Create the TD HOB list upon machine init done
i386/tdx: Add TDVF memory via INIT_MEM_REGION
i386/tdx: Use KVM_TDX_INIT_VCPU to pass HOB to TDVF
Sean Christopherson (7):
target/i386: Expose x86_cpu_get_supported_feature_word() for TDX
i386/kvm: Move architectural CPUID leaf generation to separarte helper
i386/kvm: Squash getting/putting guest state for TDX VMs
i386/tdx: Frame in tdx_get_supported_cpuid with KVM_TDX_CAPABILITIES
i386/tdx: Add hook to require generic device loader
i386/tdx: Force x2apic mode and routing for TDs
target/i386: Add machine option to disable PIC/8259
Xiaoyao Li (4):
hw/i386: Introduce kvm-type for TDX guest
linux-headers: Update headers to pull in TDX API changes
hw/i386: Initialize TDX via KVM ioctl() when kvm_type is TDX
target/i386/tdx: Finalize the TD's measurement when machine is done
