[RFE] Generic PCI Resource

[Grzegorz Grasza]

Currently, the iLO driver sets a GPU resource capability by hardware inspection (namely pci_gpu_devices).
http://docs.openstack.org/developer/ironic/drivers/ilo.html#hardware-inspection-support

I would like to propose a more generic implementation of hardware inspection and updating the node capabilities.
The name of the capability, as well as the PCI vendor and device ID list could be configured by the deployer. After creating a corresponding flavor, nova scheduler can filter nodes by flavor's extra_specs for a wide range of PCI device types.

This would be implemented in the ironic-python-agent and ironic-inspector projects.

    Add PCI devices collector to inspector

    Adds a new collector, which gathers list of PCI devices.
    Each entry is a dictionary containing 2 keys:
    - vendor-id
    - product-id
    Such information can then be used by the inspector to distinguish
    appropriate PCI devices.

[Dmitry Tantsur (divius)]

Hi! Do you plan to propose the inspector part? I'd be very interested to see it.

[Grzegorz Grasza (xek)]

Yes, we're currently working on it and testing it on our setup. Szymon will be out of work for two weeks, so we are aiming on submitting it then.

[Dmitry Tantsur (divius)]

Cool! Just please mind the feature freeze in the end of August: http://releases.openstack.org/newton/schedule.html

    Add PCI devices plugin to inspector

    Adds a new plugin to distinguish PCI devices returned by Ironic
    Python Agent. Recognized PCI devices are then registered in node
    capabilities and later can be used by nova flavors.
