[dpdk-stable] patch 'bus/pci: fix UIO resource access from secondary process' has been queued to stable release 19.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/21/20. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Luca Boccassi

Subject: [PATCH] bus/pci: fix UIO resource access from secondary process

[ upstream commit e6cf7bee1c77a0f321cea3494a106bfa5de6f53c ]

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")
