Sorry Mani, I shouldn't have spread this SOC bug. This is a bug in RTL
design, the WSTRB signal of AXI bus is not connected correctly, so the first
generation SOC cannot send message, because we mainly use RC mode, and we
cannot send PME_Turn_OFF, that is, our SOC does not support L2. I have no
choice about this, I entered the company relatively late, and our SOC has
already TO.
Ok. Just to clear my head, this patch is needed irrespective of the hw issue,
right? And with or without this patch, first revision hw cannot send any MSG
TLPs?
If so, it is fine. But is there a way we could detect those first generation IPs
and flag it to users about broken MSG TLP support? Atleast, that would make the
users aware of broken hw.
This patch is to solve the Cadence common code bug, and does not conform to
Cadence documentation.
you mean 'does'?
