Ok, I lied before.. it was a fluke it worked and required magic to repeat it..
It actually helps to fill in RAMFC entries in the correct place.
The code also clears RAMIN entirely instead of just the hash-table.
Added preliminary support for context switches (triggers the interrupts, but hangs after the switch ; something's not quite right yet).
Removed the PFIFO_REINIT ioctl. I hope it's that a good idea...
Requires the upcoming commit to the DDX.
- Mark the correct RAMIN slots as free (oops)
- Remove a VRAM alloc that shouldn't have been there (oops)
- Move HT init out of firstopen() and into dma_init()
- Setup PFIFO_RAM{HT,FC,RO} in pfifo_init()
