When fetching DMA command, make sure to convert little endian fields to host endianness (i.e. don't use memcpy).
When fetching DMA command, return the host address of the DMA command for LOAD_QUAD. Maybe this address should be cached whenever this->cmdptr changes?
When fetching DMA command, return whether the DMA command is writable.
For LOAD_QUAD, pass the address of the DMA command to xfer_quad.
Always log unexpected DMA command values.
Write full 32-bit value for LOAD_QUAD.
Write reqCount to resCount.
pci_conv_rd_data can be used to handle unaligned or 64-bit accesses in mmio regions if it's modified to include the next 32-bit value.
For pci config accesses, grackle repeats the 32-bit value. bandit uses a seemingly random number for the next 32-bit value, but we'll make it work like grackle.
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.
For example, Old World Macs have versions of Open Firmware that don't support 512 MB BARs correctly. They may attempt to set such a BAR to 0x90000000 (a 256 MB boundary) instead of 0xA0000000 (the next available 512 MB boundary).
So that you don't see identical messages "Could not restore NVRAM content from the given file."
Instead, one will mention nvram.bin and the other will mention pram.bin.
AdbKeyboard would copy the event into its own fields and set the
changed field, so that we could return the event when register was 0.
However, if a subsequent event was received before ADB polling, the
previous event would be overwritten and lost.
Fix this by maintaining a queue of events, so that we can return
everything since the last poll.
We were using an empty value on the second byte of the ADB keyboard
register 0, but that maps to the "a" key. This manifested itself
as the Key Caps DA never showing the "a" key as being down.
Switch to a non-existent key for the second byte.
