drm_dev_alloc — Allocate new DRM device
struct drm_device * drm_dev_alloc ( | struct drm_driver * driver, |
struct device * parent); |
Allocate and initialize a new DRM device. No device registration is done.
Call drm_dev_register to advertice the device to user space and register it
with other core subsystems. This should be done last in the device
initialization sequence to make sure userspace can't access an inconsistent
state.
The initial ref-count of the object is 1. Use drm_dev_ref and
drm_dev_unref to take and drop further ref-counts.
Note that for purely virtual devices parent can be NULL.
