Read ROM file once.
Identify 68K and New World ROMs.
Improve identification of Old World ROMs.
Perform checksum checks.
Identify the ROM even if the user specifies a machine option.
The previous approach of traversing the machine and its device tree
at startup to register CLI11 options was not working for dynamically
registered devices like PCI cards. This meant that options like
gfxmem_size or mon_id from the video cards could not be set.
Switch to instead registering in MachineFactory a hook function that
provides CLI flag values. We can call it when registering any property,
whether at startup or dynamically.
- Use interrupt source instead of IRQ ID in the IrqMap.
- Add a get_interrupt_controller method to mirror the set_interrupt_controller method.
- Have PCI hosts use pcihost_device_postinit to add PCI devices. This was moved from bandit's device_postinit and allows for duplicate devices by appending the slot to the registered device name.
- Fix interrupts of Pippin.
Fix interrupts of cmd646
- Make it work like other PCI devices.
- IntDetails is built into the pcibase base class.
- IntDetails is initialized by calling pci_interrupt.
- pci_interrupt checks the "enable interrupts" flag before doing an interrupt.
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.
The first option is a flag that enables MPC601 (POWER) instructions for CPUs that are not MPC601.
This can be useful for the following reasons:
1) To produce results similar to classic Mac OS which emulates MPC601 instructions on CPUs that don't implement MPC601 instructions. This option is used to compare the risu traces produced in Mac OS 9 on a G3 or G4 with DPPC.
2) May increase performance in apps that use POWER instructions on emulated machines with CPUs that are not MPC601. It is not known if any such apps exist but there could be since Apple included MPC601 emulation in classic Mac OS.
In Xcode, type Command-Shift-B to analyze every source file or Command-Shift-Control-B to analyze the current source file.
For pseudo_dma_read report FIFO underrun and init data_word in that case.
