UefiCpuPkg/CpuMpPei: Split CpuMpPei.c to two files
CpuMpPei.c contains two parts: EFI_PEI_MP_SERVICES_PPI instance and CpuMpPpi list installer. Move the EFI_PEI_MP_SERVICES_PPI instance in a new file called CpuMp.c, keep the specific logic and entry point in CpuMpPei.c, and rename the CpuMp2Pei.c to CpuMp2.c Cc: Ray Ni <ray.ni@intel.com> Cc: Jiaxin Wu <jiaxin.wu@intel.com> Cc: Zhiguang Liu <zhiguang.liu@intel.com> Cc: Dun Tan <dun.tan@intel.com> Cc: Rahul Kumar <rahul1.kumar@intel.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Chao Li <lichao@loongson.cn>

This function is used to retrieve the following information:

|
- The number of enabled logical processors in the system at the instant
|

dynamically, the number of enabled logical processors may vary during the

course of a boot session.

This service executes a caller provided function on all enabled APs. APs can

both blocking requests only. This service may only
|

|
be called from the BSP.
|
||||||
|
|
||||||
|
This function is used to dispatch all the enabled APs to the function specified
|
||||||
|
by Procedure. If any enabled AP is busy, then EFI_NOT_READY is returned
|
||||||
|
immediately and Procedure is not started on any AP.
|
||||||
|
|
||||||
|
If SingleThread is TRUE, all the enabled APs execute the function specified by
|
||||||
|
Procedure one by one, in ascending order of processor handle number. Otherwise,
|
||||||
|
all the enabled APs execute the function specified by Procedure simultaneously.
|
||||||
|
|
||||||
|
If the timeout specified by TimeoutInMicroSeconds expires before all APs return
|
||||||
|
from Procedure, then Procedure on the failed APs is terminated. All enabled APs
|

|
are always available for further calls to EFI_PEI_MP_SERVICES_PPI.StartupAllAPs()

terminated.
|

Note: It is the responsibility of the consumer of the EFI_PEI_MP_SERVICES_PPI.StartupAllAPs()
|
||||||
|
to make sure that the nature of the code that is executed on the BSP and the
|
||||||
|
dispatched APs is well controlled. The MP Services Ppi does not guarantee
|

that the Procedure function is MP-safe. Hence, the tasks that can be run in

parallel are limited to certain independent tasks and well-controlled exclusive

specified.

This function is used to dispatch all the enabled APs to the function specified

immediately and Procedure is not started on any AP.

all the enabled APs execute the function specified by Procedure simultaneously.
|
|
