Subject: question about BSP switch function
Date: Mon, 6 Mar 2017 04:38:03 +0000	[thread overview]
Message-ID: <1E4DA6F54C53C24B98E8E8D172B945AF87ADF6@ZXBJMBX02.zhaoxin.com> (raw)

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,
