Re: Multiprocessor support in AARCH64

Rebecca Cran

I committed multiprocessor support for AARCH64 last week. The platform you’re building needs to include the MpServices driver from ArmPkg/Drivers.

Hi everyone.
I'm developing an application using EDK2 and I need to implement
multiprocessor support. For the X64 architecture I was able to use
EFI_MP_SERVICES_PROTOCOL to run code in other processors, but I also
need to use this functionality in AARCH64 processors. I tried using it
on two machines and was unable to use the MP Services protocol on any
of them. Is multiprocessor support not available for ARM machines? Or
is there any other protocol to use with this architecture?
