Subject: [PATCH v3 0/2] pci/lspci: Identify Enhanced Allocation (EA) Resources
Date: Fri,  5 Feb 2016 11:59:03 -0800	[thread overview]
Message-ID: <1454702345-4014-1-git-send-email-sean.stalley@intel.com> (raw)

Identify BAR-equivalent resources that are described by EA entries
with the IORESOURCE_PCI_EA_BEI flag.

lspci cannot distinguish between resources from VF BARs and resources from EA.
This results in EA Resources being incorrectly identified as [virtual].
Adding this flag allows EA resources to be marked more accurately as [enhanced].

Although this patchset only add support for this flag to lspci,
there are other use cases (such as vfio) where knowing a resource
comes from EA would be useful.

[PATCH 1/2] is for the kernel, [PATCH 2/2] is for lspci.

Changes from V1: 
	-Rewrote commit message for linux changes

Changes from V2: 
	- Rewrote commit message for linux, fixing spelling :)
	- Added warning about resource flags being exposed in sysfs
