Summary uio_pci_generic module bind failed in X710/XL710/XXV710
Product DPDK
Version unspecified
Hardware All
OS All
Status UNCONFIRMED
Severity normal
Priority Normal
Component ethdev
Assignee dev@dpdk.org
Reporter nandinipersad361@gmail.com
Target Milestone ---

The uio_pci_generic module is not supported by XL710, since the errata of XL710
states that the Interrupt Status bit is not implemented. The errata is the item
#71 from the xl710 controller spec. The hw limitation is the same as other
X710/XXV710 NICs.

Implication:
When use --bind=uio_pci_generic, the uio_pci_generic module probes device and
check the Interrupt Status bit. Since it is not supported by X710/XL710/XXV710,
it return a failed value. The statement that these products don’t support INTx
masking, is indicated in the related linux kernel commit.

Resolution/Workaround:
Do not bind the uio_pci_generic module in X710/XL710/XXV710 NICs.

Affected Environment/Platform:
All.

Driver/Module:
Poll Mode Driver (PMD).
