AdbMouse and AdbKeyboard are subdevices of the CUDA device alongside AdbBus.
This doesn't make sense because conceptually, ADB devices hang off of the ADB
bus, not CUDA itself. An ADB bus can exist without a CUDA present, for example
Egret on older 68K Macs and the PMU on newer Power Macs. Therefore, make the ADB
device list a subhierarchy of AdbBus instead. Add a new "adb_devices" property
belonging to AdbBus that can allow users to specify ADB devices on the command
line at machine creation time, independent of the emulated bus's host. Make this
property default to "Mouse,Keyboard" to preserve existing behavior.
Shutdown will enter the debugger or quit depending on the execution mode.
Quit is different from shutdown since it is triggered outside the guest by using the host Quit menu item.
We may be transferring less data than can fit in a chunk, so we need
to ensure that xfer_cnt is clamped to 0 when transferring the last
chunk (otherwise it remains negative, and has_data() will return true).
It's also possible that the transfer size is bigger than a chunk but not
an even multiple of the chunk size, so we need to ensure that we don't
try to transfer a whole chunk in the last iteration.
More correctly initialize the device identification struct, to report
the maximum (word 47) and current (word 59) number of blocks that can be
transferred with READ_MULTIPLE and WRITE_MULTIPLE commands.
Fix post_xfer_action to write the actual data size that was written,
as opposed to an entire chunk (which may be larger).
1f2256ec81a/7ee8b9b2 were referencing a multiple_sector_count field,
but it was never set. This was resulting in an error being returned
(`READ MULTIPLE with SET MULTIPLE==0`).` We actually should use
`sec_per_block``, which bd16b7c69e introduced.
Although being optional in ATA-3 and absent in >= ATA-4,
RECALIBRATE is issued by Open Firmware 3.1.1 during device
initialization. If it fails, the drive is considered non-bootable.
Now we got two classes: IdeChannel and MacioIdeChannel.
The former models a generic IDE channel so it can be used elsewhere.
The latter implements MacIO specific configuration register(s)
and interrupt signaling.
Both cmd_pkt and data_buf class members are cast to a uint16_t pointer,
so we need to make sure they are properly aligned, otherwise it is
undefined behavior.
Take the DDRA and DDRB registers into account as well because
there is software that tries to change state of the pins configured
as inputs.
This commit fixes Cuda for Rhapsody.
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.
