Hi all,
I find EFI_MP_SERVICES_PROTOCOL is implemented on Intel architecture, but not on ARM architecture. Why is it not implemented on ARM architecture?
Short answer is because we've not seen a pressing need. If you have a specific use-case in mind, we could re-evaluate this.
It is very useful in the following use-cases: 1. To do CPU test, every core needs to be tested. 2. To flash a huge image, e.g. Android image, to a device.
Any plan about implementing it on ARM architecture?
Nothing scheduled, but we've had some thoughts about how best to go about it. My preferred route is to implement it as a thin shim layer on top of PCSI.
Best Regards,
Leif
