Public methods

armPeriodicTimerCreates a periodic timer.Method armTimerCreates a single-use timer.Method cancelTimerCancels a timer.Method chainChains an already constructed DMA chain to the next DMA chain transfer.Function template changeTimerPeriodChanges the period of a periodic timer.Method clearImmediately clears the drawing buffer.Method delayDelays the coroutine for a specified amount of time.Method disableScissorImmediately disables the scissoring of the VRAM.Method enableScissorEnables the scissoring of the VRAM.Method getClearSets a `FastFill` primitive to clear the current drawing buffer.Method getFrameCountReturns the number of frames rendered by the GPU so far.Method getNextClearSets a `FastFill` primitive to clear the next drawing buffer.Method getNextScissorGets the next scissoring region.Method getParityGet the index of the current display buffer.Method getRefreshRateReturns the refresh rate of the GPU.Method getScissorGets the current scissoring region.Method initializePerforms `initialize` as part of GPU setup, command submission and frame synchronization.Method isChainIdleGets the status of the background DMA transfer operation when initiated by a frame flip.Method isChainTransferredGets the status of the background DMA transfer operation when initiated by a frame flip.Method isChainTransferringGets the status of the background DMA transfer operation when initiated by a frame flip.Method nowGets the current timestamp in microseconds.Method pauseTimerPauses a timer.Method pumpCallbacksRuns one round of event processing.Method reinitializePerforms `reinitialize` as part of GPU setup, command submission and frame synchronization.Method resumeTimerResumes a paused timer.Method sendChainImmediately sends the current DMA chainMethod sendFragmentImmediately sends a fragment to the GPU. This is a blocking operation. See the fragments.hh file for more information.Function template sendPrimitiveSends a primitive to the GPU. This is a blocking call.Function template uploadToVRAMUploads a buffer to the VRAM as a blocking call.Method waitChainIdleWaits until the background DMA transfer operation initiated by a frame flip is complete.Method waitFifoWaits until the GPU's FIFO is ready to receive data.Method waitReadyWaits until the GPU is ready to send a command.Method

Static methods

sendRawSends a raw 32 bits value to the Data register of the GPU.Method
