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 Changes from V3 (only lspci changes): - Incremented libpci API version number - append new flag variables to the end of struct pci_dev (so we don't break binary compatiblity) - expanded comment for the resource flags - removed brackets around 1 line conditionals Alex Williamson (1): pci: Identify Enhanced Allocation (EA) BAR Equivalent resources Sean O.
