2022-03-01UefiCpuPkg: Replace Opcode with the corresponding instructions.Jason1-2/+2
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3790 Replace Opcode with the corresponding instructions. The code changes have been verified with CompareBuild.py tool, which can be used to compare the results of two different EDK II builds to determine if they generate the same binaries.

2020-12-18Revert "UefiCpuPkg/CpuDxe: Fix boot error"Laszlo Ersek1-2/+2
This reverts commit cee5b0441af39dd6f76cc4e0447a1c7f788cbb00. Commit cee5b0441af3 ("UefiCpuPkg/CpuDxe: Fix boot error", 2020-12-08) breaks CpuDxe (and with it, OVMF boot) on AMD processors. AMD processors cannot do far jumps to 64-bit targets, as documented in the AMD64 Architecture Programmer's Manual. Revert the patch until a RETFQ-based substitute is posted.

2014-11-13UefiCpuPkg/CpuDxe: Add stackless assembly AP entry pointsJordan Justen2-0/+146
The AP startup code simply jumps into this code with the CpuDxe driver without setting up a stack for the processor. Therefore, this code must setup the stack before calling into C code. This is the basic flow: * AP enters CpuDxe driver code (AsmApEntryPoint) without stack - AP grabs a lock - AP sets up stack - AP calls CpuMp.c:ApEntryPointInC - If ApEntryPointInC returns, the lock is freed, and another AP may run - The AP C code may call AsmApDoneWithCommonStack to indicate that the AP is no longer using the stack, and another may therefore proceed to use the stack and then call ApEntryPointInC Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Jeff Fan <jeff.fan@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@16347 6f19259b-4bc3-4df7-8a09-765794883524
