qinwei1 4cb5ff3353 arm64: ARMv8-r(Cortex-R82) support(add ARCH_SET_VMPIDR_EL2 option) ... Summary VMPIDR_EL2 holds the value of the Virtualization Multiprocessor ID. From architecture manual of AArch64, the behave is: -reading register MPIDR_EL1 in EL2, it's return real MPIDR_EL1 -reading register MPIDR_EL1 in EL1, it's return VMPIDR_EL2 So since NuttX for SMP is running at EL1 to read MPIDR_EL1 for identify CPU id, it's need to set VMPIDR_EL2 to MPIDR_EL1 for every CPU at boot EL2 stage. For some platform, the bootloader or hypervisor will do that at the EL2 stage, but not all. Signed-off-by: qinwei1 <qinwei1@xiaomi.com>		2023-03-01 13:23:48 +08:00
