Driver Information
------------------
-
-Driver Features
-~~~~~~~~~~~~~~~
-
-Drivers inform the DRM core about their requirements and supported
-features by setting appropriate flags in the driver_features field.
-Since those flags influence the DRM core behaviour since registration
-time, most of them must be set to registering the :c:type:`struct
-drm_driver <drm_driver>` instance.
-
-u32 driver_features;
-
-DRIVER_USE_AGP
- Driver uses AGP interface, the DRM core will manage AGP resources.
-
-DRIVER_LEGACY
- Denote a legacy driver using shadow attach. Don't use.
-
-DRIVER_KMS_LEGACY_CONTEXT
- Used only by nouveau for backwards compatibility with existing userspace.
- Don't use.
-
-DRIVER_PCI_DMA
- Driver is capable of PCI DMA, mapping of PCI DMA buffers to
- userspace will be enabled. Deprecated.
-
-DRIVER_SG
- Driver can perform scatter/gather DMA, allocation and mapping of
- scatter/gather buffers will be enabled. Deprecated.
-
-DRIVER_HAVE_DMA
- Driver supports DMA, the userspace DMA API will be supported.
- Deprecated.
-
-DRIVER_HAVE_IRQ; DRIVER_IRQ_SHARED
- DRIVER_HAVE_IRQ indicates whether the driver has an IRQ handler
- managed by the DRM Core. The core will support simple IRQ handler
- installation when the flag is set. The installation process is
- described in ?.
-
- DRIVER_IRQ_SHARED indicates whether the device & handler support
- shared IRQs (note that this is required of PCI drivers).
-
-DRIVER_GEM
- Driver use the GEM memory manager.
-
-DRIVER_MODESET
- Driver supports mode setting interfaces (KMS).
-
-DRIVER_PRIME
- Driver implements DRM PRIME buffer sharing.
-
-DRIVER_RENDER
- Driver supports dedicated render nodes.
-
-DRIVER_ATOMIC
- Driver supports atomic properties. In this case the driver must
- implement appropriate obj->atomic_get_property() vfuncs for any
- modeset objects with driver specific properties.
-
-DRIVER_SYNCOBJ
- Driver support drm sync objects.
