568f862aeb PR 2111: Do not update system clock until we can keep more accurate time. 1996-02-23 12:40:37 +00:00

ef3500b579 Attempt to work around a hardware bug that screws up DMA on the 4/100. 
Apparently, some early 4/100 DMA controllers do illegal memory access on
large ( >= NBPG ) transfers at the end of the transfer.  This appears
as SI_CSR_DMA_BUS_ERR in the csr.  To work around this, we simply
transfer the (up to 3) missing bytes from the bpr.  We were doing this
anyway, so the work-around is to ignore the bus error.

BUT!  I goofed when I implemented the "left-over byte" code for the sw!
It *should* be correct now.  Keep metrics (acceeible via DDB) on the number
of 1, 2, and 3 byte clean-ups, as well as the number of "clean" transfers,
just so we can get a clearer picture.

Thanks to Andrew Gillham <gillham@whirlpool.com> for noticing this!

a7daa2d931 - Clean up DEBUG code.

c86505a6a5 If we get a transfer with the SCSI_POLL flag set, don't use DVMA. We 
only get these during autoconfiguration and during crash dumps.  During
autoconfiguration, the transfers are small enough that DVMA won't be used
anyway.  However, using DVMA during a crash dump can be dangerous,
depending on the nature of the panic, so we avoid it.

94ca9f6aa0 New interrupt handling code. Highlights: 
- Interrupt service routines now take a pointer to
	  the device's softc, rather than a unit number.
	- Interrupt handling code in locore.s condensed.  Only
	  remaining "special" handlers are lev0 (spurious),
	  lev1 (HIL; don't ask), lev6 (clock), and lev7 (NMI).
	  Only remaining hard-coded device driver reference in
	  locore is HIL.  (clock doesn't count...)
	- "dcafastservice" eliminated.  DCA driver has new mechanism
	  to guarantee prompt interrupt service at any ipl (not
	  just level 5).
	- Interrupt code pulled out of autoconf.c and machdep.c and
	  placed in new file, isr.c
