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
