* 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).

Bugs to fix:
|
|
* render: figure out why fx-CG dclear() now takes 4.1 ms instead of 2.6 ms
|
|
|
|
Extensions on existing code:
|
|
* clock: mono support
|
|
* usb: add PC->calc reading, and interrupt pipes
|
|
* fs: support RAM files
|
|
* fs: support USB streams as generic file descriptors
|
|
* fugue: support glob() to abstract away BFile entirely
|
|
* fugue/fs: offer a primitive to remove recursively, which is native in Fugue
|
|
* bfile: implement the optimization-restart as realized by Kbd2
|
|
* kernel: better restore to userspace before panic (ensure BL=0 IMASK=0)
|
|
* project: add license file
|
|
* kernel: group linker script symbols in a single header file
|
|
* r61524: brightness control and clean the file
|
|
* core: review forgotten globals and MPU addresses not in <gint/mpu/*.h>
|
|
* core: run destructors when a task-switch results in leaving the app
|
|
* fs: support read-only files backed with GetBlockAddress() on fx-CG
|
|
* kernel: SH4- or G-III-specific linker scripts?
|
|
* keysc: global shortcut SHIFT+0+EXIT for abort() as an infinite loop break
|
|
|
|
Future directions:
|
|
* Audio playback using TSWilliamson's libsnd method
|
|
* Serial communication
|
|
* Make fx9860g projects work out of the box on fxcg50
|
|
* Base for Yatis' threads library
