create_nv_mgr()

struct NvMdev create_nv_mgr

(

)

Creates a NVIDIA manager object.

Todo:

Use proper logging.

Definition at line 42 of file manager.c.

Here is the caller graph for this function:

create_nv_mgr_mdevs()

void create_nv_mgr_mdevs	(	struct NvMdev *	mgr,
		struct Gpu *	limited,
		size_t	gpu_size,
		struct MDevRequest *	requested,
		size_t	mdev_size
	)

Creates necessary mediated devices on GPUs.

Creates mediated devices on the devices.

Side Effect:

RM Side Effect: Creates mdevs on a requested GPU.

Parameters

mgr	- Pointer to the manager for the NVIDIA driver.
limited	- GPUs to limit the requested drivers on.
gpu_size	- Size of the limited list.
requested	- Requested MDevs to use.
mdev_size	- Size of the requested list.

free_nv_mgr()

void free_nv_mgr

(

struct NvMdev *

mgr

)

Deletes a NVIDIA manager object.

Todo:

Use proper logging.

register_nv_mgr_mdevs()

void register_nv_mgr_mdevs

(

struct NvMdev *

mgr

)

Registers mdevs on the OS.

This command actually registers the MDevs in the Operating System.

Side Effect:

RM Side Effect: Creates mdevs in the OS.

Parameters

mgr	- Manager to register the MDevs for.
