pk aca7e7fa24 Just don't force the baud rate in the driver, ever. 2000-03-19 14:58:02 +00:00
pk 41fb5989fe Revise console device handling: 
* do not require a `zs' driver for console handling
	* run the console on PROM primitives until a device recognises
	  itself as a console device during normal autoconfiguration.
	* allow (keyboard) devices to take over the input channel of
	  the PROM primitive-based console device.

As a result, consinit() is much simplified and does no longer have
to "detect" devices to setup a working console device. This complexity
has moved to individual drivers which interpret the PROM information
after they have attached to decide whether or not to act as a console.

thorpej a183d34f04 - Implement cnbell() -- ring the console bell. The cn_bell entrypoint 
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

pk e2909faa19 Sanatize consinit() a bit. 1999-03-02 13:40:05 +00:00
pk 372e76a3bb Since V2 & V3 proms already pass us ihandles for stdin and stdout, 
there's no need to open the device a second time. It suffices to
just convert the `ihandles' to `phandles'.

mycroft 2a304686e6 Minor cleanup. 
Make the initializer for BAUDLO depend on PCLK directly; it was incorrect on
some ports where PCLK is not 4.9152MHz.
XXX Is the default value actually used?

mycroft be1af660c0 Don't set DCD_IE in the frontends. KGDB doesn't even use DCD, and the tty 
frontends get it from zsparam() anyway.

pk 2357b53997 Avoid race for the chip's interrupt pending status bits in zscnputc() 
by introducing a single-character queue to defer kernel console output
until the transmitter interrupt handler runs.

mrg bb07095632 as per discussion with torek, allow TC=1. also add option 
to allow TC=0.  the zilog documentation says not to allow
TC=0 -- however, i tested this and it "does work", as far
as i could tell, so, allow this use if so desired.

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 ee08e9085b Extend the size of the "soft" FIFOs which reportedly reduces the number 
of FIFO overflows on high baud rates.
However, doing so on all 4 ports would cost a whopping 64KB (at 4096 entries
per FIFO) of kernel memory. So, the FIFOs are now allocated at attach time
allowing the size for the keyboard and mouse ports to be reduced (to 128)
which should be adequate for the 1200 baud they use.
