2016-07-20UefiCpuPkg/PiSmmCpuDxeSmm: SMM_CPU_DATA_BLOCK is not clearedJeff Fan
The commit 8b9311 changed the zeroing of mSmmMpSyncData of type SMM_DISPATCHER_MP_SYNC_DATA by the following patch. - ZeroMem (mSmmMpSyncData, mSmmMpSyncDataSize); + mSmmMpSyncData->SwitchBsp = FALSE; mSmmMpSyncDataSize not only includes SMM_DISPATCHER_MP_SYNC_DATA, but also includes the SMM_CPU_DATA_BLOCK array and one BOOLEAN variable array as shown here: mSmmMpSyncDataSize = sizeof (SMM_DISPATCHER_MP_SYNC_DATA) + (sizeof (SMM_CPU_DATA_BLOCK) + sizeof (BOOLEAN)) * gSmmCpuPrivate->SmmCoreEntryContext.NumberOfCpus; This patch restores the original ZeroMem() to clear all CPU Sync data. The commit 8b9311 may cause unexpected behavior. v2: Mentioned CandidateBsp array in comments to make it more accurate.

2016-07-20UefiCpuPkg/CpuDxe: StartupAllAPs in parallel modeJeff Fan
SetMemoryAttributes() will sync BSP's MTRRs settings to all APs by StartupAllAPs service in serial mode. It may caused much performance impact if there are too much processors in system. This update is to invoke StartupAllAps in parallel mode. IA32 SDM does suggest to program MTRRs in parallel mode.

2016-07-20UefiCpuPkg/MtrrLib: Remove MTRRs display from MtrrSetAllMtrrs()Jeff Fan
MtrrSetAllMtrrs() maybe used by APs to sync BSP's MTRR settings. BSP's MTRR setting should be displayed if EFI_D_CACHE flag is set when MTRR updated. In MtrrSetAllMtrrs(), it's not necessary to display MTRR setting again due to the MTRR settings should be always same among BSP/APs. This updating could avoid APs output MTRR setting at the same time and make display message corrupted.

Commits 28ee5816465b1 and 246cd9085f806 added these ENDs as part of the manual conversion from *.asm files. However, the ENDs makes no sense for NASM. Although they don't break the build, NASM complains about them: label alone on a line without a colon might be in error (This NASM warning category dates back to NASM 0.95, commit 6768eb71d8deb.)

Use 16bit and 32bit assembly code to replace hard code db. In V2: add 0x67 prefixes to far jumps Without the a32 modifier under FLAT32_JUMP, and the a16 modifier under LONG_JUMP, nasm doesn't generate the 0x67 prefixes, and the far jumps don't work. (For the former, KVM returns an emulation failure. For the latter, KVM performs a triple fault (guest reboot).) By forcing the 0x67 prefixes we end up with the same machine code as the one open-coded in "MpFuncs.asm". This bug breaks S3 resume in the Ia32X64 + SMM_REQUIRE build of OVMF.

Currently, if the memory length to be programmed is less than the remaining size of one Fixed-MTRR supported, RETURN_UNSUPPORTED returned. This is not correct. This is one regression at 07e889209034ba94bfac9e765b8a50ef344daef2 when we updated ProgramFixedMtrr() to remove the loop of calculating Fixed-MTRR Mask. This fix will calculate Right offset in Fixed-MTRR beside left offset. It supports small length (less than remaining size supported by Fixed-MTRR) to be programmed.
