mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

pk 8a1606d530 Don't return `XS_DRIVER_STUFFUP' too easily; this can hose buffer cache
writes. Say XS_TIMEOUT in stead so the scsi code will retry.

pk ee08e9085b Extend the size of the "soft" FIFOs which reportedly reduces the number
of FIFO overflows on high baud rates.
However, doing so on all 4 ports would cost a whopping 64KB (at 4096 entries
per FIFO) of kernel memory. So, the FIFOs are now allocated at attach time
allowing the size for the keyboard and mouse ports to be reduced (to 128)
which should be adequate for the 1200 baud they use.

pk ce474272f1 Prevent synch negotiation on ESP100 chips 1995-11-28 22:49:31 +00:00
pk 9bf3251e46 Lots of major and minor bug fixes and changes.
- properly do MSG_IN handshaking, so we can actually receive multi-byte msgs.
- do synch negotiation (now that the above works).
- handle disconnects.
There are a few trial-and-error bits at points where the docs I have are
particularly ambiguous about the state of chip and/or SCSI bus.

Things to do:
- more cleanup
- deal with MSG_OUT phase better
- keep some "config reg 3" bits per target (ie. FASTCLK and FASTSCSI).

and re-synchronize before re-scheduling pending operations.

pk e4fcc8ab5a Move DMA chip draining to dmaintr() and drain when a (possibly partial)
transfer ends in stead of doing it before starting a new transfer.
Use a different CSR bit to wait for "chip not busy" (may be necessary to
make this conditional on chip revision).

pk a3f2bf19e4 Various:
- make esp_poll() approximate the given timeout value.
	- introduce esp_abort(), and use it for timed out commands; make		  targets and driver less confused.
	- make {free,ready,nexus}-list management somewhat more coherent.
	- make sure we only proceed down the state machine in espintr()
	  if there really is an interrupt pending.

chuck 1779adf6be minor cleanups:
- don't let pcyl go unassigned if we have a non-sunos disklabel.
		if nothing else, guess pcyl = ncyl + acyl.
	- don't use bogus disklabel data if disk label is invalid
		(xdgetdisklabel() now returns if label was ok or not).
	- move xddriver decl. before start of actual code (cleanup).

chuck 2aff99a206 bug fix: xddummystrat() was clearing all but B_BUSY when it should
have been clearing just B_BUSY (s/B_BUSY/~B_BUSY/).    this
	fixes hard hang when reading disklabel when booting system.
minor clean up: added a few prototypes and only fool with bootpath
	if booting the system (in xdattach).
