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 Alex Williamson (1): pci: Identify Enhanced Allocation (EA) BAR Equivalent resources Sean O.
