Undefined.
Log in XPUNCERRSTS register.
Log in XPGLBERRSTS, XPGLBERRPTR registers.
If error is forwarded to the global error registers, it is
logged in global non-fatal log registers - GFERRST,
GFFERRST, GFNERRST, GFFERRTIME.

Drop the transaction.
Log in XPUNCERRSTS register.
Log in XPGLBERRSTS, XPGLBERRPTR registers.

for complete
details.

Unsupported Request response
for the associated transaction on
the PCI Express interface.
Error logged in VT-d Fault Record register.
Error logged in VTUNCRRSTS and VTUNCERRPTR
registers.
Error logging also happens (on the GPA address) per
the PCI Express AER mechanism (address logged in
AER is the GPA). Errors can also be routed to the IIO
global error logic and logged in the global non-fatal
registers.

Error logged in VT-d fault record register.
Error also logged in the VTUNCERRSTS register and
in VTUNCERRPTR registers.
These errors can also be routed to the IIO global
error logic and logged in the global fatal registers.
