QPI to PCIe read: IIO
returns all ‘1s’ and normal
response to Intel

QPI to
indicate master abort.

QPI to PCIe NP write: IIO
returns normal response.
PCIe to PCIe read/NP-write:
‘Unsupported request’ is
returned

to original PCIe
requester.
SMBus accesses: IIO returns
‘UR’ response status on SMBus.
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 - GNERRST,
GNFERRST, GNNERRST, GNFERRTIME.

IIO encountered a
PCIe ‘Unsupported
Request’ condition,
on inbound
address decode,
as listed in Table
3-6, with the
exception of SAD
miss (see C6 for
SAD miss), and
those covered by
entry #11
PCIe read: ‘Unsupported
request’ completion is returned
on PCIe.
PCIe non-posted write:
‘Unsupported request’
completion is returned on PCIe.
The write data is dropped.
PCIe posted write: IIO drops the
write data.
Log error per PCI Express AER requirements for
unsupported request.
