mrg c98a14ad90 update these for poll(2) changes. 1996-09-12 01:35:34 +00:00
cgd adeb6b4058 replace sequences of 8 spaces with tabs (only one instance). kill 
unnecessary newlines after return statements but before function
close-braces.

thorpej fa0e4a3082 Make the SPARC kernel compile again after recent tty cdevsw changes. 1996-09-05 09:32:47 +00:00
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).

unsigned.   should fix xdc watchdog timeouts noted in port-sparc
by nathanw@mit.edu.

abrown 0c6696de2d Take advantage of new am7990 sc_nocarrier() function in order to do auto- 
matic media detection on Sun4m machines which support multiple media
(UTP and AUI). New function lenocarrier() switches media type when called
if no link? flags are set.

Redefine link flags for Lance ethernet (le):
	<none>:	switch between media as needed to find carrier (autodetect)
		Preference to whatever the PROM is using (AUI if not booted
		from the network)
	link0:	use UTP port only
	link1:	use AUI port only

This allows Sun4m machines with dual media Lance ethernet adapters to
boot from the network on the UTP port.

	machines with IOMMUs(?).

pk 2d2098c11b Check for `configuration parent' differently: compare against "sbus" 
rather than "ledma".
 1996-05-16 22:57:32 +00:00
pk 3f1283a92f Re-arrange code that looks for the esp driver to allow for the fact that 
any "dma" device (i.e. not just "espdma") can have an OBP child. This is
the case with (at least some) SBus SCSI boards.

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 ac9df157aa 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.

abrown 6b768c677a Now that we have lehwinit() for the Sun4m, make sure that we wait 20ms 
after changing the cable type, as specified in the chip documentation.
Also, sanity-check that sc_dma is valid in case a Sun4m ever exists without
a ledma.
