Update: add --force, --enable-sriov to opae.io#3038
Open
Conversation
Add --force and --enable-sriov options to the subparser for opae.io init. The --force option enables controlling the force parameter to vfio_init() that was previously hard-coded to False. The --enable-sriov option, when given, causes opae.io init to write 'Y' to /sys/module/vfio_pci/parameters/enable_sriov. The default value for both options is False.

There was a problem hiding this comment.
The Linux kernel folks would suggest trying to minimize indentation by something like the following:
if not os.path.exists(sriov):
LOG.error("Cannot enable sriov because {sriov} does not exist")
return FALSE

Description
Add --force and --enable-sriov options to the subparser for opae.io init. The --force option enables controlling the force parameter to vfio_init() that was previously hard-coded to False.
The --enable-sriov option, when given, causes opae.io init to write 'Y' to /sys/module/vfio_pci/parameters/enable_sriov.
The default value for both options is False.
