commit a316d7ac91d302085b5c35d76db703f2208ec026
Author: Laszlo Ersek <lersek@xxxxxxxxxx>

    OvmfPkg/SmmControl2Dxe: select broadcast SMI if available
    
    When writing to IO port 0xB2 (ICH9_APM_CNT), QEMU by default injects an
    SMI only on the VCPU that is writing the port. This has exposed corner
    cases and strange behavior with edk2 code, which generally expects a
    software SMI to affect all CPUs at once. We've experienced instability
    despite the fact that OVMF sets PcdCpuSmmApSyncTimeout and
    PcdCpuSmmSyncMode differently from the UefiCpuPkg defaults, such that they
    match QEMU's unicast SMIs better. (Refer to edk2 commits 9b1e378811ff and
    bb0f18b0bce6.)
    
    Using the new fw_cfg-based SMI feature negotiation in QEMU (see commits
    50de920b372b "hw/isa/lpc_ich9: add SMI feature negotiation via fw_cfg" and
    5ce45c7a2b15 "hw/isa/lpc_ich9: add broadcast SMI feature"), we can ask
    QEMU to broadcast SMIs. Extensive testing from earlier proves that
    broadcast SMIs are only reliable if we use the UefiCpuPkg defaults for the
    above PCDs. With those settings however, the broadcast is very reliable --
    the most reliable configuration encountered thus far.
    
    Therefore negotiate broadcast SMIs with QEMU, and if the negotiation is
    successful, dynamically revert the PCDs to the UefiCpuPkg defaults.
    
    Setting the PCDs in this module is safe:
    
    - only PiSmmCpuDxeSmm consumes them,
    
    - PiSmmCpuDxeSmm is a DXE_SMM_DRIVER, launched by the SMM_CORE
      (MdeModulePkg/Core/PiSmmCore/PiSmmCore.inf),
    
    - the SMM_CORE is launched by the SMM IPL runtime DXE driver
      (MdeModulePkg/Core/PiSmmCore/PiSmmIpl.inf),
    
    - the SMM IPL has a DEPEX on EFI_SMM_CONTROL2_PROTOCOL,
    
    - OvmfPkg/SmmControl2Dxe produces that protocol.
    
    The end result is that PiSmmCpuDxeSmm cannot be dispatched before
    SmmControl2Dxe installs EFI_SMM_CONTROL2_PROTOCOL and returns from its
    entry point. Hence we can set the PCD's consumed by PiSmmCpuDxeSmm in
    SmmControl2Dxe.

    OvmfPkg: dynamic defaults for PcdCpuSmmApSyncTimeout, PcdCpuSmmSyncMode
    
    Move the platform-specific default values for these PCDs from the
    [PcdsFixedAtBuild] / [PcdsFixedAtBuild.X64] sections to the
    [PcdsDynamicDefault] section.
