- Increase I/O space from 22 bits (4 MB) to 23 bits (8 MB).
- Add Special Cycles and Interrupt Acknowledge Cycles at 14 MB offset.
- Pass Through range at 16 MB offset is 16 MB size. VGA and 24 bit physical addresses can go here.
- Bandit is 32 MB except for pci1 which has GrandCentral at Bandit's 16 MB offset.
We only need up to BE_FB_OFFSET + this->vram_size.
If vram_size is 8MB, then make sure the last 4K is not mapped to BAR 0 because the macOS driver likes to map BAR 2 at that location.
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.
Have the entire dbdma program executed by scheduling each iteration in the CPU loop.
This is done only for devices that use the dbdma program to drive data input/output (has_data_callbacks) rather than have the device drive the dbdma program.
If bits 6 and 7 are 3, then the divisor should be 1 instead of 16.
0 -> 2x
1 -> 4x
2 -> 8x
3 -> 1x (not 16x).
This change affects RGB 12 inch dislay 512 x 384 60Hz mode in Platinum.
- 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.
