mycroft aaad0e1149 Sync with Alpha version. 1996-09-28 03:21:04 +00:00
thorpej 8d5c3b9cd1 Sync with the alpha version, fixing several SCSI protocol bugs.
NOTE: THESE FILES ARE NOW IDENTICAL TO THEIR ALPHA COUNTERPARTS.
The C preprocessor does the Right Thing when these files are built
on a SPARC.  This makes it significantly easier to diff the two
versions (until a real MI 53c9x driver is done, hint hint).

cgd adeb6b4058 replace sequences of 8 spaces with tabs (only one instance). kill
unnecessary newlines after return statements but before function
close-braces.
1996-09-09 18:01:30 +00:00
cgd 71ad30d0e9 (1) set scsi_link channel to either the appropriate channel (if a
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
    single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
    function, and kill any locally-defined print function.
1996-08-28 18:59:15 +00:00
cgd 2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

pk 2266b8dd57 Use the setting of the ESPCFG2_FE bit rather than revision number to decide

pk 6a4a26da0c Correct test for `dmachild' which failed on `esp at obio*' configs (PR#2541). 1996-06-12 12:46:21 +00:00
pk 94cd1644ee Avoid the "features enable" bit on ESP100A's; apperently this is a source

pk bc77c57c13 espattach() requires DMA to be configured. For now, panic if it is not. 1996-05-21 19:09:43 +00:00
pk 50e92fd71d Use configuration file flags to disable reselection and/or sync negotiation,
on a per target basis (until the driver can sort things out on its own).

Test against "sbus" in stead of "espdma" to find out where in the
configuration tree we are: an esp can be the child of a "dma" on SBus
add-on boards.

thorpej 3cd14f7597 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

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).

pk 996526aa02 Make error recovery actually work, i.e. don't hang on SCSI bus resets
and re-synchronize before re-scheduling pending operations.
Things seem to be a fair bit stabler now.
1995-11-03 16:47:43 +00:00
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.

pk db43cabe32 Re-instate configuration print routines, following Chris' suggestion.
Only prints something if there's no scsi bus to attach.
1995-09-14 20:38:53 +00:00
pk 9d7c17bfcb We have no need for `esp_print()'; the only child we expect is a `scsibus',
and there's nothing to say if it isn't there. Returning -1 is an error
anyway as noted by Chuck Cranor.

pk 7b7773a0c5 Use bootpath_store() to set next boot component; used in dk_establish()
to match `sd' devices against the PROM's boot path.

Detect DMA "overshoots" when handling odd-sized transfer sizes (e.g., xfers
from/to raw partitions), by using the "Transfer Pad" command when the
transfer count reaches zero.

pk 4770e5e7c5 Try to recover from multi-byte messages sent by a target for which we
get an "Illegal command" (why is this?) when we try to pull it in.
On detection of this condition, we reset the SCSI bus and simply stop asking
this target for an identify messages, for now.

pk f6cd1eeea7 Integrate changes from Chuck Cranor for the Sun 4/100.
Support for multiple register banks on SBUS devices (based on patches
from Francis Dupont).
Highlights:
	romaux defines an array of register spaces.
	pay attention to `vactype'.
	quirks handling 4/100 idiosyncracies.
