Function Documentation

int drm_add_edid_modes ( struct drm_connector *  connector,
struct edid *  edid 
)

drm_add_edid_modes - add modes from EDID data, if available : connector we're probing : edid data

Add the specified modes to the connector's mode list.

Return number of modes added or 0 if we couldn't find any.

Definition at line 1972 of file drm_edid.c.

int drm_add_modes_noedid ( struct drm_connector *  connector,
int  hdisplay,
int  vdisplay 
)

drm_add_modes_noedid - add modes for the connectors without EDID : connector we're probing : the horizontal display limit : the vertical display limit

Add the specified modes to the connector's mode list. Only when the hdisplay/vdisplay is not beyond the given limit, it will be added.

Return number of modes added or 0 if we couldn't find any.

void drm_mode_sort ( struct list_head *  mode_list)

drm_mode_sort - sort mode list : list to sort

LOCKING: Caller must hold a lock protecting .

int  maxY,
int  maxPitch 
)

drm_mode_validate_size - make sure modes adhere to size constraints : DRM device : list of modes to check : maximum width : maximum height : max pitch

LOCKING: Caller must hold a lock protecting .

The DRM device () has size and pitch limits. Here we validate the modes we probed for against those limits and set their status as necessary.

int drm_mode_vrefresh ( const struct drm_display_mode *  mode)

drm_mode_vrefresh - get the vrefresh of a mode : mode

LOCKING: None.

Return 's vrefresh rate in Hz or calculate it if necessary.

FIXME: why is this needed? shouldn't vrefresh be set already?

RETURNS: Vertical refresh rate. It will be the result of actual value plus 0.5. If it is 70.288, it will return 70Hz. If it is 59.6, it will return 60Hz.

int drm_mode_width ( struct drm_display_mode *  mode)

drm_mode_width - get the width of a mode : mode

LOCKING: None.

Return 's width (hdisplay) value.

FIXME: is this needed?

RETURNS: ->hdisplay
