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 |
