int radeon_driver_firstopen_kms

(

struct drm_device *

dev

)

radeon_driver_firstopen_kms - drm callback for first open

: drm dev pointer

Nothing to be done for KMS (all asics). Returns 0 on success.

Definition at line 387 of file radeon_kms.c.

void radeon_driver_lastclose_kms

(

struct drm_device *

dev

)

radeon_driver_firstopen_kms - drm callback for last close

: drm dev pointer

int radeon_driver_load_kms	(	struct drm_device *	dev,
		unsigned long	flags
	)

radeon_driver_load_kms - Main load function for KMS.

: drm dev pointer : device flags

This is the main load function for KMS (all asics). It calls radeon_device_init() to set up the non-display parts of the chip (asic init, CP, writeback, etc.), and radeon_modeset_init() to set up the display parts (crtcs, encoders, hotplug detect, etc.). Returns 0 on success, error on failure.

Definition at line 74 of file radeon_kms.c.

int radeon_driver_open_kms	(	struct drm_device *	dev,
		struct drm_file *	file_priv
	)

radeon_driver_open_kms - drm callback for open

: drm dev pointer : drm file

On device open, init vm on cayman+ (all asics). Returns 0 on success, error on failure.

Definition at line 413 of file radeon_kms.c.

void radeon_driver_postclose_kms	(	struct drm_device *	dev,
		struct drm_file *	file_priv
	)

radeon_driver_postclose_kms - drm callback for post close

: drm dev pointer : drm file

On device post close, tear down vm on cayman+ (all asics).

Definition at line 458 of file radeon_kms.c.

void radeon_driver_preclose_kms	(	struct drm_device *	dev,
		struct drm_file *	file_priv

radeon_driver_preclose_kms - drm callback for pre close

: drm dev pointer : drm file

On device pre close, tear down hyperz and cmask filps on r1xx-r5xx (all asics).

Definition at line 493 of file radeon_kms.c.

int radeon_driver_unload_kms

(

struct drm_device *

dev

)

radeon_driver_unload_kms - Main unload function for KMS.

: drm dev pointer

This is the main unload function for KMS (all asics). It calls radeon_modeset_fini() to tear down the displays, and radeon_device_fini() to tear down the rest of the device (CP, writeback, etc.). Returns 0 on success.

Definition at line 47 of file radeon_kms.c.

int radeon_enable_vblank_kms	(	struct drm_device *	dev,
		int	crtc
	)

radeon_enable_vblank_kms - enable vblank interrupt

: drm dev pointer : crtc to enable vblank interrupt for

Enable the interrupt on the requested crtc (all asics). Returns 0 on success, -EINVAL on failure.

Definition at line 536 of file radeon_kms.c.

u32 radeon_get_vblank_counter_kms	(	struct drm_device *	dev,
		int	crtc
	)

radeon_get_vblank_counter_kms - get frame count

: drm dev pointer : crtc to get the frame count from

Gets the frame count on the requested crtc (all asics). Returns frame count on success, -EINVAL on failure.

Definition at line 515 of file radeon_kms.c.

int radeon_get_vblank_timestamp_kms	(	struct drm_device *	dev,
		int	crtc,
		int *	max_error,
		struct timeval *	vblank_time,
		unsigned	flags
	)

radeon_get_vblank_timestamp_kms - get vblank timestamp

: drm dev pointer : crtc to get the timestamp for : max error : time value : flags passed to the driver

Gets the timestamp on the requested crtc based on the scanout position. (all asics). Returns postive status flags on success, negative error on failure.

Definition at line 591 of file radeon_kms.c.

int radeon_info_ioctl	(	struct drm_device *	dev,
		void *	data,
		struct drm_file *	filp
	)

radeon_info_ioctl - answer a device specific request.

: radeon device pointer : request object : drm filp

This function is used to pass device specific parameters to the userspace drivers. Examples include: pci device id, pipeline parms, tiling params, etc. (all asics). Returns 0 on success, -EINVAL on failure.
