[Qemu-devel] [PATCH v7 2/6] spapr_pci: encode class code including Prog


From: Nikunj A Dadhania
Subject: [Qemu-devel] [PATCH v7 2/6] spapr_pci: encode class code including Prog IF register
Date: Thu, 11 Jun 2015 16:32:25 +0530

Current code missed the Prog IF register. All Class Code, Subclass,
and Prog IF registers are needed to identify the accurate device type.

For example: USB controllers use the PROG IF for denoting: USB
FullSpeed, HighSpeed or SuperSpeed.
