***SPAM*** Re: ***SPAM*** Fwd: [ofw][PATCH-1/3] [IBIOU] Expose vendor defined device in ibiou

Leonid,

I am still waiting for your comments on the ibiou patch for user defined
device creations from IBAL stack.
It would be great to receive your comments so that we can move in this patch
asap.

Regards
Deepak

> IBIOU driver doesn't create child PDO's on discovering a EVIC IOC.
> It's behavior for SRP target IOCs is not altered and child devices for SRP
> targets will get created on their discovery.
>
> IBIOU keeps a global list of reachable IOCs in iou_globals. IBIOU
> add/delete entries in this list on IOC ADD and IOC REMOVE PnP events.
> User mode utility "qlgcvnic_config" is used to list all the reachable IOCs
> to the user and then to create the VNIC PDOs.
> "qlgcvnic_config" uses device IOCTLs to communicate with the IBIOU driver.
> IBIOU creates the devices only if sees that EVIC IOC is reachable from the
> particular CA.
> "qlgcvnic_config" utility writes this device information into the registry
> also, so that IBIOU can pick up these device creation information on
> next reboot.
> In initialization phase, IBIOU reads the child device information from the
> registry and makes a list of VNIC child devices to be created.
> On each IOC add events, it traverses the child device list (prepared during
> initialization) and create the child PDO for matching child device entries.
