我們先看看i915_drv.c里面申明的driver變量：

static struct drm_driver driver = {

/* don't use mtrr's here, the Xserver or user space app should

* deal with them for intel hardware.

*/

.driver_features =

DRIVER_USE_AGP | DRIVER_REQUIRE_AGP | /* DRIVER_USE_MTRR |*/

DRIVER_HAVE_IRQ | DRIVER_IRQ_SHARED | DRIVER_GEM,

.load = i915_driver_load,

.unload = i915_driver_unload,

.open = i915_driver_open,

.lastclose = i915_driver_lastclose,

.preclose = i915_driver_preclose,

.postclose = i915_driver_postclose,

.suspend = i915_suspend,

.resume = i915_resume,

.device_is_agp = i915_driver_device_is_agp,

.enable_vblank = i915_enable_vblank,

.disable_vblank = i915_disable_vblank,

.irq_preinstall = i915_driver_irq_preinstall,

.irq_postinstall = i915_driver_irq_postinstall,

.irq_uninstall = i915_driver_irq_uninstall,

.irq_handler = i915_driver_irq_handler,

.reclaim_buffers = drm_core_reclaim_buffers,

.get_map_ofs = drm_core_get_map_ofs,

.get_reg_ofs = drm_core_get_reg_ofs,

.master_create = i915_master_create,

.master_destroy = i915_master_destroy,

#if defined(CONFIG_DEBUG_FS)

.debugfs_init = i915_gem_debugfs_init,

.debugfs_cleanup = i915_gem_debugfs_cleanup,

#endif

.gem_init_object = i915_gem_init_object,

.gem_free_object = i915_gem_free_object,

.gem_vm_ops = &i915_gem_vm_ops,
