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.
scsibus has a new method attach_scsi_devices which is used by all machines to populate a SCSI bus with one or more hard drives or CD-ROM drives.
HDDs are specified by the hdd_img property.
CDs are specified by the cdr_img property.
Multiple images are delimited by a colon :
attach_scsi_devices is called by the scsi controller after the scsi controller has attached itself to the scsi bus.
The bus suffix is applied to the property name.
Curio has no suffix so it will use hdd_img and cdr_img properties.
Mesh is expected to have a suffix of 2 so it will use hdd_img2 and cdr_img2 properties.
HDDs will skip SCSI ID 3 unless 7 HDDs are added, in which case, the seventh HDD will use ID 3.
CDs will start at SCSI ID 3, go to 7, then down to 0.
SCSI IDs are skipped if a device is already using that SCSI ID.
ScsiCdrom and ScsiHD no longer use REGISTER_DEVICE or DeviceDescription or PropMap which is normal for devices that can have multiple instances.
PCCard is used by PowerBook G3 Wallstreet in Open Firmware 2.0.1.
CardBus is probed in New World Macs starting from at least Open Firmware 4.1.9f1 sometime after Open Firmware 3.1.1.
- Create PCIBase from common stuff in PCIDevice.
- Add PCIBridgeBase. These have a primary bus number, secondary bus number, and subordinate bus number which are used to determine if PCI type 1 config cycle should be passed.
- Change PCIBridge to use PCIBridgeBase instead of PCIDevice.
- Add PCICardBusBridge which uses PCIBridgeBase.
