Generic driver template
To use this template, you must at least define the following (samples given for the MGA driver):
Definition in file drm_drv.c.
| #define DRM_CORE_IOCTL_COUNT ARRAY_SIZE( drm_ioctls ) |
|
read |
Called whenever a process performs an ioctl on /dev/drm.
| inode | device inode. |
| file_priv | DRM file private. |
| cmd | command. |
| arg | user argument. |
Looks up the ioctl function in the ioctls table, checking for root previleges if so required, and dispatches to the respective function.
| int drm_lastclose | ( | struct drm_device * | dev | ) |
Take down the DRM device.
| dev | DRM device structure. |
Frees every resource in dev.
