Hi, Dhanasekar,
Linux boot parameters allow specifying serial baudrate. An example would be:
earlycon=uart8250,mmio32,0x,115200n81 console=ttyS2,115200
Please make sure the serial device info (including MMIO or I/O address and
the device name) matches your platform in above settings.
Current function has low performance because it calls GetApicId
many times.
New logic call GetApicId once and base on this value to search
the processor.
V2 changes:
Rollback V1 change which base on stack info to get AP index because
this solution may return error AP index if stack buffer
When resume from S3 and CPU loop mode is MWait mode,
if driver calls APs to do task at EndOfPei point, the
APs can't been wake up and bios hang at that point.
The root cause is PiSmmCpuDxeSmm driver wakes up APs
with HLT mode during S3 resume phase to do SMM relocation.
After this task,

Hi All,
As stack maybe overflow in some case and it will caused error AP index been
returned. Also I don't find any register will be used different in each Aps. So
I will update my patch to only base on APIC ID to get the AP.
Thanks,
Eric

But it needs extra effort to let BSP copy uCode from flash to
memory. Also BSP already enable cache in SEC phase, so it use
less time to relocate uCode from flash to memory. After
