419df4825a usb: Define new astable write region and use it to move NFA logic onto the host. 
The write protocol handling is reworked on the firmware side.

0f78a93f66 Rename FLUXOP_NOFLUX -> FLUXOP_SPACE 2020-10-27 09:51:16 +00:00
Keir Fraser
e7062e3ad8 usb: Send periodic noflux opcodes during long periods of no flux. 
This new no-flux opcode replaces the long-flux opcode:
 long-flux = no-flux + regular-flux
Also rearrange the code a bit to avoid repetition.

9b4b69da85 usb: Place index timings in-band within the flux read stream. 
This removes the low limit on max index timings per read request.

12028bdffe f7: Do not wait for write buffer to completely fill at Full Speed. 
Now the buffer is 128kB, it takes ~150ms to fill it at FS.

93c5200a65 f7: Define new 'ext_ram' section to allocate data to SRAM1/SRAM2 
Note that these areas are cached by the ARM CPU, and since the
cache does not automatically maintain coherency with DMA operations,
don't do DMA to or from ext_ram!!

73c3902dce bandwidth: New bandwidth measurement command 
Currently measures only average bandwidth. We really care about
mimimum bandwidth, so adding that is a todo.

8799fda304 Introduce erase_flux command to erase a track. 
Use this in 'gw write' to erase unformatted/empty tracks.
Remove the --adjust-speed option: We basically always want this.
 2020-04-21 10:47:41 +01:00

773e9933dd floppy: Remove delayed-index option from WRITE_FLUX command. 
We will deal with non-index write splice instead by writing more
than one full revolution, but starting at index always.

2dc37fe3ec Remove double underscore prefix from __packed and __aligned() definitions. 
It is polluting the GCC namespace and breaks the build with GCC v9.

51178ae11d usb: Use magic baud rates as out-of-band commands to Greaseweazle.
