jonathan	7fb01f01ae	Print TC bus speed properly when attaching device, since the SCSI ... clock is taken (and computed) from the TC bus clock. See PR 4380.	1997-10-31 06:29:59 +00:00
mhitch	0ae3de1a27	Use direct DMA with the IOASIC ASC SCSI interface. DMA buffering can be ... re-enabled with ASC_IOASIC_BOUNCE. All DMA buffered processing is now done in the bus-specific DMA routines in asc_ioasic.c and asc_tc.c. Disable several informational messages dealing with non-empty FIFO conditions, but allow enabling with ASC_DIAGNOSTIC for troubleshooting.	1997-07-28 19:39:22 +00:00
jonathan	4631885e91	Kill __BROKEN_INDIRECT_CONFIG on pmax. ... Based on a patch from Chris G. Demetriou, December 1996.	1997-07-21 05:39:02 +00:00
jonathan	1f44934407	* Change Sprite MACH_xxx prefix to MIPS_xxx. ... * Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).	1997-06-22 07:42:25 +00:00

mhitch	184eb4a5e9	Remove extraneous output - ascattach() already did it.	1996-10-12 16:15:34 +00:00
christos	b5c4f2fc49	printf -> kprintf, sprintf -> ksprintf	1996-10-10 20:25:34 +00:00
jonathan	8eca2b2bb4	* Rewrite asc driver with ``mi'' backend and parent-specific front-end ... cfattach code for TC SCSI option cards and ioasic 53c94 baseboard SCSI. ascvar.h: shared softc declarations asc_ioasic.c: ioasic front-end code. asc_tc.c: Turbochannel option (and 5000/200 basebard) front-end code. * ioasic_attach meeds more work to eliminate pmax_type dependency and to verify the clocks speed passed to 53c94. * Add prototypes for asc script entry points; should compile with -Wstrict-prototypes -Wmissing-prototypes. * Use tcvar.h interface. The usage of tc_syncbus() and tc_mb() may not be quite stylistically on an Alhpa, but it apparently makes no difference on the eerly-generation Alpha CPUs in TC Alphas.	1996-09-25 21:07:46 +00:00
