f6dba67570 Read up to 32 bytes. The ESCC *needs* 8, and it doesn't hurt to leave some 
slop in case there are clone chips with a deeper FIFO.

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.

86b6520e41 more TS_WOPEN to tp->t_wopen changes 1998-03-21 23:36:19 +00:00

019508faee Well, I don't have a Cyclades board, but I needed the alpha kernels 
to compile. I made the changes that seemed to make sense tracking the
shift from TS_WOPEN  to tp->t_wopen- but they may be wrong. I wasn't
subscribed to tech-kern so I missed the discussion, and C. Hannum
was not particularly enlightening. Sorry if this isn't quite right.

77f499595c Switch to a bus_space(9)-based device attachment scheme. 
- device attachment arguments contain bus-specific
	  address and interrupt levels.

	- devices must call back on bus map functions to get their
	  addresses and interrupt levels translated properly.

	- sun4m's obio bus is treated like an Sbus slot.

	- the sun4-style obio bus has its own attach arguments
	  and map functions.

2f2b4dae56 Optimize some cycles out of the clock interrupt handler when 
USE_LEDS is defined.

727b8bc7ac Charles Hannum pointed out that if a clock interrupt was posted while 
we were in ledcontrol(), the heartbeat twinkler would just punt on
updating the LED even though it had already updated the status.  (This
was broken in v1.73 of locore.s).

Rather than resurrect the old code, simplify ledcontrol() and don't
bother with mutual exclusion.  As mentioned by the comments describing
this function, we really don't need to be that precise.  We do, however,
want to guarantee instructions that modify the status variable directly,
so the function is now primarily inline assembly.
