question about BSP switch function

question about BSP switch function

[Tiger Liu]

Hi, experts:
I have a question about BSP switch function.
PI Spec defined a Ppi and a Protocol to provide SwitchBSP() function.
EFI_MP_SERVICES_PPI.SwitchBSP()
EFI_MP_SERVICES_PROTOCOL.SwitchBSP()

If SEC code found BSP had some errors, so PEI phase code could use mp services ppi to switch BSP to other ap cores.

So, my question is:
Except BSP errors scenario, is there other use case needed to switch bsp core?

Thanks

best wishes,

PI MP Services provide such capability to switch BSP.

Except for BSP error, platform may have other reason to switch BSP. Anyway, this is platform choice to switch BSP per its request.
