- 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.
Bit 5 of the channel status register of the SCSI0 DMA channel
reflects the DREQ signal from Curio.
The old SCSI API still used in some Macintosh applications
- most notably HD SC Setup and Drive Setup - relies on this API
and that signal to be implemented.
- Add IOBusDevice (nvram_addr_hi_dev) for NVRAM addr hi.
- Add IOBusDevice (nvram_dev) for NVRAM data.
- Make all IOBusDevices use the same code.
- Log error if 4 least significant bits of offset are not zero.
- Correctly byte swap the value before passing it to the IOBusDevice.
- When reading, duplicate the bytes in a word or dword like a real Power Mac does.
- Add all the interrupts including DMA.
- Modify the Interrupt to IRQ_ID translation so the interrupts belonging to the first set of 32 interrupts don't need to be shifted.
While dingusppc only emulates 32-bit Macs (for now), it is possible for a 32-bit Power Mac to use a PCIe card that has 64-bit BARs.
finish_config_bars is added to scan the cfg values of the BARs and determine their type. The type is stored separately so that it does not need to be determined again.
The type can be I/O (16 or 32 bit) or Mem (20 or 32 or 64 bit). A 64 bit bar is two BARs, the second contains the most significant 32 bits.
set_bar_value uses the stored type instead of trying to determine the type itself. It is always called even when the firmware is doing sizing. For sizing, It does the job of setting the bar value so do_bar_sizing is now just a stub.
Every PCIDevice that has a BAR needs to call finish_config_bars after setting up the cfg values just as they need to setup the cfg values. Since they need to do both, maybe the cfg values should be arguments of finish_config_bars, then finish_config_bars() should be renamed config_bars().
