e1849a2bfd dbdma: Schedule interpret_cmd. 
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.

15986a4e4f dbdma: Allow clearing only control bits. 
Only control bits can be set and cleared by software.
Command bits and status bits cannot be cleared.

f415a63b76 dbdma: Allow Stop command to set xferStatus. 
Some software may check the status flags of a Stop DBDMA descriptor.

50e661f804 dbdma: Resume should continue DBDMA program. 
Just like Start does.

96875a1278 dbdma: Clear active flag if paused flag is set. 
The active flag is cleared when the pause flag is set, so why shouldn't the active flag be cleared when the start flag is set with the pause flag is already set?

11d61359c1 dbdma: Add data callbacks. 
Allow the dbdma program to initiate reading/writing by adding in and out callbacks.
Support the DBDMA flush command by adding a flush callback. If the transfer completes, then clear the flush flag, otherwise leave it unchanged.
Clear the flush flag after it is copied to the xferStatus of the DBDMA command.

1d75730d44 dbdma: Do interrupt on main thread. 
These may be triggered by other threads (such as for audio) so use the timer manager to handle them in the main thread.

dcdfaabedf dbdma: skip transfer commands with reqCount=0. 2024-04-07 20:39:24 +02:00

bc582e64cc dbdma: Clear cmd_in_progress before callback. 
Because the callback might start DMA commands.

2d8f2422b3 dbmda: Fix dma output res_count update. 
Use this->res_count to track amount of data transferred.

29d13aef09 dma: Add is_active method for input channels. 
Since DBDMA contains an input and output channel, rename the existing is_active method to is_out_active.

fb0396923f Fix dma STORE_QUAD and LOAD_QUAD. 
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.

b0dc893a05 dma: Add name to dma classes. 
For logging purposes, each DMA channel should have a name.

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.
