int i2o_device_claim

(

struct i2o_device *

dev

)

i2o_device_claim - claim a device for use by an OSM : I2O device to claim

Do the leg work to assign a device to a given OSM. If the claim succeeds, the owner is the primary. If the attempt fails a negative errno code is returned. On success zero is returned.

Definition at line 60 of file device.c.

int i2o_device_claim_release

(

struct i2o_device *

dev

)

i2o_device_claim_release - release a device that the OSM is using : device to release

Drop a claim by an OSM on a given I2O device.

AC - some devices seem to want to refuse an unclaim until they have finished internal processing. It makes sense since you don't want a new device to go reconfiguring the entire system until you are done. Thus we are prepared to wait briefly.

Returns 0 on success or negative error code on failure.

int i2o_device_parse_lct

(

struct i2o_controller *

c

)

i2o_device_parse_lct - Parse a previously fetched LCT and create devices : I2O controller from which the LCT should be parsed.

The Logical Configuration Table tells us what we can talk to on the board. For every entry we create an I2O device, which is registered in the I2O core.

Returns 0 on success or negative error code on failure.

void i2o_device_remove

(

struct i2o_device *

i2o_dev

)

i2o_device_remove - remove an I2O device from the I2O core : I2O device which should be released

Is used on I2O controller removal or LCT modification, when the device is removed from the system. Note that the device could still hang around until the refcount reaches 0.
