-Query state:
- ProcRRGetScreenInfo/ProcRRGetScreenResources
- RRGetInfo
-
- • Request configuration from driver, either 1.0 or 1.2 style
- • These functions only record state changes, all
- other actions are pended until RRTellChanged is called
-
- ->rrGetInfo
- 1.0:
- RRRegisterSize
- RRRegisterRate
- RRSetCurrentConfig
- 1.2:
- RRScreenSetSizeRange
- RROutputSetCrtcs
- RRModeGet
- RROutputSetModes
- RROutputSetConnection
- RROutputSetSubpixelOrder
- RROutputSetClones
- RRCrtcNotify
-
- • Must delay scanning configuration until after ->rrGetInfo returns
- because some drivers will call SetCurrentConfig in the middle
- of the ->rrGetInfo operation.
-
- 1.0:
-
- • Scan old configuration, mirror to new structures
-
- RRScanOldConfig
- RRCrtcCreate
- RROutputCreate
- RROutputSetCrtcs
- RROutputSetConnection
- RROutputSetSubpixelOrder
- RROldModeAdd • This adds modes one-at-a-time
- RRModeGet
- RRCrtcNotify
-
- • send events, reset pointer if necessary
-
- RRTellChanged
- WalkTree (sending events)
-
- • when layout has changed:
- RRPointerScreenConfigured
- RRSendConfigNotify
-
-Asynchronous state setting (1.2 only)
- When setting state asynchronously, the driver invokes the
- ->rrGetInfo function and then calls RRTellChanged to flush
- the changes to the clients and reset pointer if necessary
-
-Set state
-
- ProcRRSetScreenConfig
- RRCrtcSet
- 1.2:
- ->rrCrtcSet
- RRCrtcNotify
- 1.0:
- ->rrSetConfig
- RRCrtcNotify
- RRTellChanged

+Query state:
+ ProcRRGetScreenInfo/ProcRRGetScreenResources
+ RRGetInfo
+
+ • Request configuration from driver, either 1.0 or 1.2 style
+ • These functions only record state changes, all
+ other actions are pended until RRTellChanged is called
+
+ ->rrGetInfo
+ 1.0:
+ RRRegisterSize
+ RRRegisterRate
+ RRSetCurrentConfig
+ 1.2:
+ RRScreenSetSizeRange
+ RROutputSetCrtcs
+ RRModeGet
+ RROutputSetModes
+ RROutputSetConnection
+ RROutputSetSubpixelOrder
+ RROutputSetClones
+ RRCrtcNotify
+
+ • Must delay scanning configuration until after ->rrGetInfo returns
+ because some drivers will call SetCurrentConfig in the middle
+ of the ->rrGetInfo operation.
+
+ 1.0:
+
+ • Scan old configuration, mirror to new structures
+
+ RRScanOldConfig
+ RRCrtcCreate
+ RROutputCreate
+ RROutputSetCrtcs
+ RROutputSetConnection
+ RROutputSetSubpixelOrder
+ RROldModeAdd • This adds modes one-at-a-time
+ RRModeGet
+ RRCrtcNotify
+
+ • send events, reset pointer if necessary
+
+ RRTellChanged
+ WalkTree (sending events)
+
+ • when layout has changed:
+ RRPointerScreenConfigured
+ RRSendConfigNotify
+
+Asynchronous state setting (1.2 only)
+ When setting state asynchronously, the driver invokes the
+ ->rrGetInfo function and then calls RRTellChanged to flush
+ the changes to the clients and reset pointer if necessary
