compose_vm_id()

static uint32_t compose_vm_id ( uint32_t  t, uint32_t  i  )

inlinestatic

Inline function to create VM specific Event IDs.

Definition at line 37 of file manager.c.

event_init()

static int event_init ( int  ctl_fd, struct NvResource *  res, uint32_t  event, uint32_t  notify, uint32_t  flags  )

static

This makes a event handler for the VM manager.

Parameters

ctl_fd	- Control file descriptor.
res	- Parent resource on the base of the system.
event	- Event id.
notify	- Notification settings.
flags	- Flags to use for the event.

Returns

Returns a file descriptor to associate to the event.
