drm_kunit_helper_alloc_drm_device

#define drm_kunit_helper_alloc_drm_device	(		_test,
			_dev,
			_type,
			_member,
			_feat
	)

Value:

    ((_type *)__drm_kunit_helper_alloc_drm_device(_test, _dev,      \
                              sizeof(_type),        \
                              offsetof(_type, _member), \
                              _feat))

drm_kunit_helper_alloc_drm_device - Allocates a mock DRM device for KUnit tests @_test: The test context object @_dev: The parent device object @_type: the type of the struct which contains struct &drm_device @_member: the name of the &drm_device within @_type. @_feat: Mocked DRM device driver features

This function creates a struct &drm_driver and will create a struct &drm_device from @_dev and that driver.

@_dev should be allocated using drm_kunit_helper_alloc_device().

The driver is tied to the @_test context and will get cleaned at the end of the test. The drm_device is allocated through devm_drm_dev_alloc() and will thus be freed through a device-managed resource.

Returns: A pointer to the new drm_device, or an ERR_PTR() otherwise.

drm_kunit_helper_alloc_drm_device_with_driver

#define drm_kunit_helper_alloc_drm_device_with_driver	(		_test,

                               offsetof(_type, _member),        \
