Add absolute coordinates for tablets. Absolute coordinates is relative to window so it can't work for multiple displays? Doesn't work for single display without mouse driver modification.
Add arbitrary number of buttons. Previously, only one mouse button was supported.
Add arbitrary number of bits. Previously, only 7 bits per axis was supported which is good enough for relative movement but not absolute movement.
Allow the dbdma program to initiate reading/writing by adding in and out callbacks.
Support the DBDMA flush command by adding a flush callback. If the transfer completes, then clear the flush flag, otherwise leave it unchanged.
Clear the flush flag after it is copied to the xferStatus of the DBDMA command.
The first packet the one sec mode should send is a mode 1 real time packet, same as GET_REAL_TIME.
A mode 2 packet is the same but doesn't include the time.
They are incomplete or unused (includes cmd and count but not the data and the count isn't used). Might as well get everything from the class fields in_buf and in_count.
GET_REAL_TIME was using the wrong offset and wasn't setting out_count.
May need to add time zone offset which could be different between host and guest.
get-time and set-time can be tested in Open Firmware.
SET_REAL_TIME is used by the Date/Time Control Panel when you change the date.
It is unknown what method Mac OS uses to get the time at boot. Mac OS 8.6 does not use GET_REAL_TIME during boot, so the time is left as 12:00 AM Jan 1, 1904.
Last step of CMD_COMPLETE_STEPS includes INTSTAT_SO to indicate to CurioSCSIController::fsmCompleting that it returned both a status byte and a message byte in the FIFO.
- For pdm/amic, real_dma_xfer is called when SCSI_DMA_Ctrl has the run bit set.
- For tnt/grandcentral, dma_wait is called when the DBDMA is started (run bit is set). It will call real_dma_xfer when the phase and sequence are DATA_IN/RCV_DATA or DATA_OUT/SEND_DATA.
- dma_wait and real_dma_xfer uses a one shot timer instead of a loop to continue doing DMA while also giving time to the CPU. This and the above changes handles the case where the DBDMA is started before setting up the transfer phase and sequence.
- dma_stop will stop the one shot timer when the DBDMA channel is stopped.
bytes_out is used instead of the removed cur_buf_cnt.
data_ptr is setup by prepare_data instead of process_command.
Not sure why scsicdrom doesn't set bytes_out in prepare_data.
