gwr 81f2d0b179 Move si_reset_adapter() from si.c into the bus-specific modules. 
Support the Sun3/470 (sun3x).  Adapt to the new DVMA interface.
Set the si_xxx_options in the config file (easier for users).
 1997-10-17 03:33:34 +00:00
gwr 5a1f692161 Sync. with the sun3x (mostly cosmetic changes). 1997-10-17 03:25:05 +00:00
gwr 38b2ba3e3f typo 1997-10-07 20:05:00 +00:00
gwr c9d8d6ae1d Use sizeof(struct ieob) instead of a sun3-specific macro, 
so this driver will work on the sun3x as well.  (Works!)

gwr b298a0b98c fix warnings 1997-10-07 17:56:30 +00:00
gwr 076ab3f536 Tweak the console support a little (more like the sparc version). 1997-10-06 21:04:21 +00:00
gwr 210e726aba Use vm_offset_t to represent control space addresses, because 
they are more like physical addresses in that you can not just
dereference a pointer to access the space.  (Also, if you use a
pointer type for such things, gdb will _try_ to deference it.)

gwr 0ec1cda62f Move the call to cninit() up a level (easier to find). 1997-10-04 19:46:17 +00:00
bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices 
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

jeremy 335b7a2d00 Duplicate changes recently made to the SPARC version of this file: 
Do not print warnings if selection of a target via DMA was interrupted
by another target.

jeremy fc60f1979e Prevent RAM disk hooks from compiling until sun3 md_root.c can support 
ram disk images that are read in from the outside.
Sync with some old local changes.

gwr 589bdf49d5 si_intr: if our CSR indicates an interrupt, return 1. 1997-04-28 22:10:41 +00:00
gwr df35245ac0 Fix a bug where OBIO locators were not presented to the children. 
Rename obio_alloc to obio_mapin; add comments, etc.  (like sun3x)
 1997-04-28 22:02:43 +00:00
gwr 388bf0e0e0 Rename obio_alloc/obio_mapin and check for obio in match functions

gwr 479d3fa66d No longer needs an early init call (just normal autoconfig). 1997-04-28 21:51:49 +00:00
gwr e2ca51d2a1 Fixed OBIO locators bug, so this can do the normal thing now. 
Also improved handling of spurious interrupts, and sync up with
the sparc version.

thorpej 1d987a161b #include <net/if_media.h> 1997-03-17 03:17:34 +00:00
is 07b064e02e New ARP system, supports IPv4 over any hardware link. 
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
 1997-03-15 18:09:08 +00:00
gwr 4756c63625 Call isr_soft_request() at most once per zshard interrupt.

 1997-01-27 16:57:12 +00:00
gwr 090dfd13c2 Now that interrupts are enabled AFTER autoconfiguration, put in the 
cute little trick where the zs interrupts are enabled as soon as the
zs driver has done its attachments.   That allows a console break to
enter the debugger during the rest of autoconfiguration.

gwr 769fe0dfca Get rid of some cruft in the match function. 1996-10-30 00:24:32 +00:00
gwr aac9e275ac Add a "submatch" function to the obio bus driver so the children 
of this driver can get rid of the cruft in their match functions.
 1996-10-30 00:20:01 +00:00
gwr d6dfd783d9 Checkpoint new version of this driver with support for the "Type A" 
variant of the CG4 (the one with the AMD colormap DACs).  This has
been tested only on the "Type B" H/W at this point (Brooktree DACs).
Thanks to Ezra Story and Scott Ellis for the "Type A" support.

mycroft b3eac79b64 tty stop functions really should return void, not int, and certainly not both. 1996-09-02 06:43:16 +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).
 1996-08-27 21:53:46 +00:00
chuck c0bae2d189 sync with sparc version: 
repair XDC_HWAIT macro to handle the fact that waithead is now
unsigned.   should fix xdc watchdog timeouts noted in port-sparc
by nathanw@mit.edu.
 1996-08-12 20:28:54 +00:00
gwr bf7ab63c97 Move some of the DMA engine initialization from the "start" routine 
to the "setup" routine.  Doing the initialization earlier prevents
nasty race conditions where the 5380 prefetch changes the counter.

gwr dc066b6a10 KGDB support 1996-06-17 15:40:36 +00:00
gwr 3274834c18 Use the PROM->input_source setting instead of EEPROM to determine 
where the console is, because that is correct if, for example, you
boot with the diag/norm switch set for diagnostics and the EEPROM
is set for keyboard/display.

thorpej dedd4cceab Fix typo, noticed by Curt Sampson <curt@portal.ca>. 1996-05-09 21:15:47 +00:00
thorpej 69351e2be6 Changed struct ifnet to have a pointer to the softc of the underlying 
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.

thorpej 0584bf86a8 Make the MI LANCE driver standalone, and use cfattach to resolve

Changed struct ifnet to have a pointer to the softc of the underlying

if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_start)()

cgd d7d306aeb7 change LANCE copy & zero functions' names to start with amd7990_, and 
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).

chuck 718ac5d246 [import changes from sparc port] 
- moved disk_busy() call from xdstrategy() to xdc_startbuf()
        [prevents disk_unbusy panic when disk is loaded (if no
        free IOPBs, xdstrategy() would queue the buffer for pickup
        by xdcintr() but xdcintr() would never call disk_busy().
        xdc_startbuf() is a better place since all bufs are routed
        through here]   problem detected by girish@dworkin.wustl.edu,
        diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
        XDC_FREE() [don't want to access a data structure that was just put
        on a free list]

chuck 8f339409b7 sync with sparc: 
- move disk_attach() to before reading the disk label as per Jason.
	otherwise we are reading into an unallocated buffer (oops!)

thorpej 5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

gwr 5d5c8d0d4b Latest, greatest version of the new NCR driver. 
DMA works!  Interrupts work!  Disconnect/reselect works!
To be paranoid, leave that all disabled for now...

gwr 93d0f65970 New SCSI driver for the NCR5380, by David Jones. 
Does DMA with interrupts.  Much faster than our old
driver which did only PIO transfers. (Thanks David!)
Could be used on the amiga, and probably others...
