drochner b95651b752 set carrier early if used as console or kgdb line, fixes PR kern/6547

jonathan 0588cdfc88 Update user-level PPS-API to match -05 draft. 
Change PPS_<xxx> ioctls to PPS_IOC_<xxx>.

jonathan b31080319e Fix nanosecond/microsecond botch in PPSAPI: 
remove bogus TIMESPEC_TO_TIMEVAL() after applying any {assert,clear} offset.

ross 4b0326d939 Get rid of delay() in com_common_putc() because the Shark delay() is borked 
and can't be called until after the timers are setup. (It should not use
a timer, or it should have a fallback algorithm.)
 1999-04-19 19:27:31 +00:00
thorpej 552465011e Revert revision 1.159. The correct answer was not to re-break the 
serial console support, but rather to fix the Shark delay().
 1999-04-18 22:02:47 +00:00
mrg 833fb0ac7f back date this file to version 1.155 which works on the shark. 1999-03-31 12:44:04 +00:00
mycroft f487bc59aa Nuke bogus extra variable, too. 1999-03-29 13:40:41 +00:00
mycroft 85ad0d175c Fix bogons in previous change: 
* The fact that IIR_NOPEND was not set on entry does *not* mean that no
  transmission was in progress.  Besides, we don't want to throw away receive
  interrupts either.
* In the !clearirq case, we didn't splx().
 1999-03-29 13:21:15 +00:00
ross 6a228da053 Mods to com_common_putc(). When doing kprintf() or kgdb output: 
1. don't clear the irq unless it was clear before transmitting
2. also do various bus_space_barrier() ops
Stops console from freezing when kprintf interrupts tty driver output.

drochner 525932e022 make the probe stricter to catch cases where the chipset doesn't pull 
the data lines to "high" for not-existant devices

mycroft 0c7afe477d Separate the tiocm code into functions, like the z8530 code, and fix the same 
DTR bug.
 1999-02-03 23:57:27 +00:00
mycroft 9be96dda95 Fix an inconsistency: PPS was turned off on first open, but the mode may have 
still claimed it was enabled.

thorpej d1fba4e7e5 Don't use M_WAITOK to allocate the ring buffer; we could be in interrupt 
context.  Reported by Lennart Augustsson.

jonathan bbc2d1522a PPS support from April, reworked and extended to match the PPS-API 
Internet Draft (draft-mogul-pps-api-02.txt).
 1998-06-10 12:06:23 +00:00
mycroft 2bb5067e13 Move the code to wait for carrier on a tty into a common function, since it 
depends only on device-independent state bits.
Implement SunOS-style `dialout' devices.

(Thanks Charles and Marc for your advices).

mycroft 06ec9f646f Arrange to call com_break() and com_modem() at splserial(). 
It's simpler this way.  Really.
 1998-02-19 09:23:38 +00:00
thorpej 5fe6759646 Fix serial console support, which was broken by the previous revision: 
- In the console getc routine, block until a character becomes ready
  (no, really, we mean it).  This routine should _never_ time out.
- In the console putc routine, if the UART has trouble, do NOT proceed
  to print a diagnostic message, which would recursively invoke the
  console putc routine ad nauseum.

enami 9d13bc6e0e Restore system priority level before return from comopen(). 1998-02-06 03:25:34 +00:00
cgd 9bffcfef75 change #ifdefs keying on "alpha" to key on "__NO_SOFT_SERIAL_INTERRUPT" 
instead, and define that on NetBSD/alpha and NetBSD/arm32.
 1998-02-02 23:01:02 +00:00
cgd c2f42b2213 Implement a flag to indicate that the driver attached correctly. 
This is useful in the case where an attachment's probe routine
verifies that there is indeed hardware present but something goes
"wrong" in the attach causing the device to be unusable.  (Without
keeping track of this, in that case incorrect ports could be
accessed or uninitted pointers could be deferenced on open or at
other times.)
 1998-02-02 22:54:55 +00:00
marc 1d4b77e754 split com_attach_subr into attach stuff and per-open initialization stuff 
add timeouts to all splserial() while loops so bugs elsewhere don't cause
the com driver to wedge the machine
 add power management support

mycroft 13e9b38191 Slight optimization in soft input routine. 1997-11-03 08:20:35 +00:00
mycroft 067898abb8 Mostly cosmetic and performance changes: 
* Make the ring buffer size and water marks patchable, and allocate the buffer
  separately.
* Do the ttymalloc() at attach time.
* Reorganize the receive buffer so the status and data pair are next to each
  other.  This is slightly faster.
* Make sure we actually do turn off interrupts in comclose() if we have DDB
  configured and it's not the console.  (D'oh!!!!)
* When we exhaust the current transmit run, turn off transmit interrupts in
  comintr(), so we're fairly sure we don't get another one.
* Nuke the silly lsrmap[] idea; it's slower in the normal case.
* Cache the l_rint pointer in the soft interrupt routine.

mycroft d0df1f96f4 Add additional splserial()s in comopen() and comclose(). These are not 
necessary on the i386 port, but may be on others.
 1997-11-01 20:31:57 +00:00
drochner d52df86460 Print probe result after the LCR is restored. Otherwise, bad 
things happen if we are the console.
Restore to the prevoius value (not to hardwired 8N1) because this
could be set by the serial console initialization.
