e011d86742 amic: don't reset cur_buf_pos if we've drained the DMA buffer
Otherwise if pull_data is called again, it will think that it still
has data available in the buffer (rem_len will be non-zero) and
random data at the buffer location will be returned.

This manifested itself as noise being played back in the JS
implementation of the SoundServer. The cubeb implementation was not
affected because it stops polling once it's told it has no more
data in the buffer. Both approaches are valid (the JS version pads
data with silence), and the DMA buffer should support both.

35c86ad6bf Clean up #includes
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

5787d49e9b Prevents crashing for Big Mac
For some reason, on Windows, whether it be VS2022 or Clang, it will crash when trying to write to a Big Mac register if you don't specify the exact name of the component within Heathrow.

This commit fixes that.

cc17035e67 pcidevice: improve BAR configuration. 2023-02-04 17:57:46 +01:00

2a64f547cc Add 64-bit BAR support.
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().
