Hi
I have basic question over SMC call in ARM64 architecture.
I am working on 8 core system,
say when core-0 calls SMC and this is in progress , at same time can core-1 do smc call and enter into EL3 ?
Is this possible two SMC handler are running at same time
thx
In my opinion yes. SMC call is an Synchronous Exception Type out of 4 defined by the VBAR. A core interrupted is the only the invoked the SMC. So the same handler can be run at the same time but on different cores.
