Re: [coreboot] PCIe PME vs ACPI Interrupt

[Martin Roth]

Hi Gailu,
  Sorry, wake on lan wasn't tested during the Bayley Bay development, 
so something was probably missed.  I'm doing some baytrail work right 
now, so I might get around to looking at it and pushing a change, but I 
can't make any guarantees about when or if that might happen.

Regards,
Martin

Hi Experts,

I am working on S3 wakeup from PCIE WAKE Signal on Baytrail SOC 
(Bayleybay board) with Intel FSP.
When I send WOL packet ACPI interrupt count does not increase though 
PCIe PME interrupt count increases.

Can you please provide some pointers why I am not getting ACPI 
interrupt for the wake event?

in /proc/interrupts, PCIe PME counter increments and acpi counter 
remains 0.
 9:          0          0  IO-APIC-fasteoi   acpi
