Subject: bus/pci: fix UIO resource access from secondary process
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e6cf7bee1c77a0f321cea3494a106bfa5de6f53c;p=dpdk.git

bus/pci: fix UIO resource access from secondary process

For PCI devices presented through igb_uio, pcidev->mem_resource[] is
not populated when the device is initialized for secondary process.

Initialize pcidev->mem_resource[] with pci-bar mapped addresses.

Fixes: eee16c964cd6 ("pci: support multiple PCI regions per device")
