SMC call on ARM64

uditknit

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.
