2016-02-24UefiCpuPkg/CpuDxe: Don't use gBS->StallJordan Justen
The CpuDxe driver may run before the gEfiMetronomeArchProtocolGuid protocol is installed. gBS->Stall does not work until this arch protocol is installed.

2015-11-17UefiCpuPkg: CpuDxe: broadcast MTRR changes to APsLaszlo Ersek
The Quark_EDKII_v1.1.0/IA32FamilyCpuBasePkg/CpuArchDxe driver applies any MTRR changes to APs, if the EFI_MP_SERVICES_PROTOCOL is available. We should do the same. Additionally, the broadcast should occur at MP startup as well, not only when MTRR settings are changed. The inspiration is taken from Quark_EDKII_v1.1.0/IA32FamilyCpuBasePkg/CpuMpDxe/ (see the EarlyMpInit() function and its call sites in "ProcessorConfig.c"). (Sync patch r18632 from main trunk.)

2015-11-17UefiCpuPkg: CpuDxe: Wait for APs to enter idle loopMichael Kinney
Address a race condition in first call to StartupAllAPs() with SingleThread set to TRUE in the MP initialization. If the APs have not entered their idle loop before StartupAllAPs() is called, then some of the APs will be in an unexpected state, and StartupAllAPs() will hang. This is the hang condition that is only seen when SingleThread parameter is set to TRUE and StartupAllAPs() is called very shortly after mAPsAlreadyInitFinished is set to TRUE that releases the APs to complete their initialization. An internal function has been added to check if all APs are in the sleeping state in their idle loop. On the first call to StartupAllAPs(), this internal function is used in a loop to make sure the APs are in a state that is compatible with the use of StartupAllAPs(). PcdCpuApInitTimeOutInMicroSeconds is used as the maximum wait time for the APs to enter their idle loop. If all APs have not entered their idle loop within the timeout, then an ASSERT() is generated.

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
