PCI-Express version 1.1 doesn't support link training error
giovane.anhaia@...
Hi,
I'm working with PCI-Express diagnostics on UEFI using edk2. On PCI-Express Base Specification 1.0a there's a bit defined as "Link Training Error" on "Link Status Register (Offset 12h)".
Specs from 1.1 up define the same bit as "Undefined".
Does somebody know if there's an alternative way to check a link training error in these newer PCI-Express specs?
