effectively full. The code is believed to be functionally complete now. Some code cleanup is included at no extra charge in this version. Fri Mar 13 20:21:57 1998 Frank Ch. Eigler <fche@cygnus.com> * sky-vu1.c: (dump_mem): Commented out function to satiate warning-ful compilation. * sky-pke.c: (pke_reset): New function, called explicitly at initialization and at FBRST. (pke_fifo_flush): New function to flush (skip over) existing quadwords in FIFO. (pke_fifo_fit): New function to add space for new quadword in FIFO. (pke_fifo_access): New function to absolute-index into FIFO. (pke_fifo_old): New function to remove old quadwords from FIFO. (pke_begin_interrupt_stall): New function to abstract interrupt-caused stalls. (pke_*): Access PKE FIFO only thorugh pke_fifo functions. (pke_pcrel_*): Renamed pke_pc_* functions. (pke_code_unpack): Numerous logic tweaks for latest UNPACK behavior changes & clarifications from SCEI. * sky-pke.h (struct pke_fifo): New explicit FIFO representation. (struct pke_device): Use struct above. (PKE_DEBUG): Removed macro as misnomer. * sky-hardware.c: Moved *_cmd_install declarations out. * sky-hardware.h: Moved *_cmd_install declarations in.
