Lephe	6910714c2c	asyncio: remove unused field asyncio_op_t.flying_w	2023-02-16 16:09:53 +01:00
Lephe	af5c16a3d3	usb: massively improve writing logic ... * Move logic around tracking transfers to asyncio.c. * Add a "short buffer" holding 0-3 bytes between writes, so that the driver performs only 4-byte writes in the FIFO and a short write in the commit, if needed. - This is partially due to me thinking at some point that degrading writing size was impossible, but it might actually be possible by writing to FIFO/FIFO+2 or FIFO/FIFO+1/FIFO+2/FIFO+3. - In any case I think this new approach wins on performance. * Get rid of unit_size since we now always use 4 bytes. * Add a waiting function which is used in usb_close() (and once tested should be used in world switches too). * Eliminate some of the special cases for the DCP, though not all (in particular I can't get the commit to rely on the BEMP interrupt yet, nor can I properly clear PID to NAK when unbinding).	2023-02-09 23:00:44 +01:00
