This is done for OvmfPkg because it currently depends upon a SMM variable GetVariable ()implementation as a simple method to exercise the SMM driver stack. This allows the following commands to be used for variables such as Boot####, BootOrder, and BootNext to test SMM timing and stability differences on the BSP (e.g. CPU#0) vs an AP (e.g. CPU#1). # taskset -c 0 efibootmgr # taskset -c 1 efibootmgr Cc: Ard Biesheuvel Cc: Laszlo Ersek Cc: Liming Gao Cc: Jordan Justen Cc: Hao A Wu Signed-off-by: Michael Kubacki --- OvmfPkg/OvmfPkgIa32.dsc | 1 + OvmfPkg/OvmfPkgIa32X64.dsc | 1 + OvmfPkg/OvmfPkgX64.dsc | 1 + 3 files changed, 3 insertions(+) diff --git a/OvmfPkg/OvmfPkgIa32.dsc b/OvmfPkg/OvmfPkgIa32.dsc index 66e944436a..4861e2342b 100644 --- a/OvmfPkg/OvmfPkgIa32.dsc +++ b/OvmfPkg/OvmfPkgIa32.dsc @@ -428,6 +428,7 @@ !if $(SMM_REQUIRE) == TRUE gUefiOvmfPkgTokenSpaceGuid.PcdSmmSmramRequire|TRUE gUefiCpuPkgTokenSpaceGuid.PcdCpuSmmEnableBspElection|FALSE + gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache|FALSE !endif [PcdsFixedAtBuild] diff --git a/OvmfPkg/OvmfPkgIa32X64.dsc b/OvmfPkg/OvmfPkgIa32X64.dsc index 51c2bfb44f..f316d97d6a 100644 --- a/OvmfPkg/OvmfPkgIa32X64.dsc +++ b/OvmfPkg/OvmfPkgIa32X64.dsc @@ -433,6 +433,7 @@ !if $(SMM_REQUIRE) == TRUE gUefiOvmfPkgTokenSpaceGuid.PcdSmmSmramRequire|TRUE gUefiCpuPkgTokenSpaceGuid.PcdCpuSmmEnableBspElection|FALSE + gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache|FALSE !endif [PcdsFixedAtBuild] diff --git a/OvmfPkg/OvmfPkgX64.dsc b/OvmfPkg/OvmfPkgX64.dsc index ba7a758844..546649f0a2 100644 --- a/OvmfPkg/OvmfPkgX64.dsc +++ b/OvmfPkg/OvmfPkgX64.dsc @@ -433,6 +433,7 @@ !if $(SMM_REQUIRE) == TRUE gUefiOvmfPkgTokenSpaceGuid.PcdSmmSmramRequire|TRUE gUefiCpuPkgTokenSpaceGuid.PcdCpuSmmEnableBspElection|FALSE + gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache|FALSE !endif [PcdsFixedAtBuild] -- 2.16.2.windows.1
