There is no need for qemu to synchronize tsc and VMM can't access to guest TSC. Actually do_kvm_synchronize_tsc() hits assert due to failure to write to guest tsc. > qemu/target/i386/kvm.c:235: kvm_get_tsc: Assertion `ret == 1' failed.

Use tdx_ioctl() to invoke KVM_TDX_INIT, by way of tdx_init(), during kvm_arch_init(). KVM_TDX_INIT configures global TD state, e.g. the canonical CPUID config, and must be executed prior to creating vCPUs. Note, this doesn't address the fact that Qemu may change the CPUID configuration when creating vCPUs, i.e. punts on refactoring Qemu to provide a stable CPUID config prior to kvm_arch_init(). Explicitly set subleaf index and flags when adding CPUID Set the index and flags when adding a CPUID entry to avoid propagating stale state from a removed entry, e.g. when the CPUID 0x4 loop bails, it can leave non-zero index and flags in the array.

Xu" Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" From: Isaku Yamahata Add support for loading TDX's Trusted Domain Virtual Firmware (TDVF) via the generic loader. Prioritize the TDVF above plain hex to avoid false positives with hex (TDVF has explicit metadata to confirm it's a TDVF). Enumerate TempMem as added, private memory, i.e. E820_RESERVED, otherwise TDVF will interpret the whole shebang as MMIO and complain that the aperture overlaps other MMIO regions.

It assumes -action reboot=shutdown instead of silently ignoring vcpu reset. TDX module spec version 344425-002US doesn't support vcpu reset by VMM. VM needs to be destroyed and created again to emulate REBOOT_ACTION_RESET. For simplicity, put its responsibility to management system like libvirt because it's difficult for the current qemu implementation to destroy and re-create KVM VM resources with keeping other resources. If management system wants reboot behavior for its users, it needs to - set reboot_action to REBOOT_ACTION_SHUTDOWN, - set shutdown_action to SHUTDOWN_ACTION_PAUSE optionally and, - subscribe VM state change and on reboot, (destroy qemu if SHUTDOWN_ACTION_PAUSE and) start new qemu.

Because posted interrupt is edge-trigger and VMM needs to hook guest EOI to re-inject level-triggered interrupt if the level still active, level-trigger isn't supported for TD Guest VM. Prevent trigger mode from setting to be level trigger with warning. Without this guard, qemu can result in unexpected behavior later.
