6ab46d52a5 Don't use NULL in non-pointer contexts. 1996-07-12 04:12:25 +00:00

d805b866fa This driver supports the SDL Communications RISCom/N2 ISA cards that is
based on the HD64570 chip. Both the 1 and 2 port cards is supported.

Line speeds of up to 2Mbps is possible. At this speed about 95% of the
bandwidth is usable with 486DX processors.

The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.

At the moment only the X.21 interface is tested. The others may need
tweaks to the clock selection code.

d2700ee639 Use the standard timer (interrupt) frequency while calibrating the clocks.
Testing with the high frequency of 20000 Hz (to find problems) only found
the problem that this frequency is too high for slow i386's.

Disable interrupts while setting the timer frequency.  This was unnecessary
before rev.1.57 and forgotten in rev.1.57.  The critical (i8254) interrupts
are disabled in another way at boot time but not in the sysctl to change
the frequency.

ad0c0c784f Change the way moused talk to syscons, now its only delivering mouseevents
via an ioctl (MOUSE_ACTION).
Fixed a couple of bugs (destructive cursor, uncut, jitter).
Now applications can use the mouse via the MOUSE_MODE ioctl, its
possible to have a signal sent on mouseevents, makeing an event loop
in the application take over mouseevents.

17b944a6a7 When writing the settings for stop bits and output hardware flow control,
things tend to work better if you write the settings to the correct

will solve a few problems that have been reported to me.

Also, take a shot at fixing the serial BREAK processing, what was there
before never really worked.  (There is a PR on this I think)

de4d1b835e Some news for syscons (long overdue):
Real support for a Textmode mousecursor, works by reprogramming the
charset. Together with this support for cut&paste in text mode.
To use it a userland daemon is needed (moused), which provides
the interface to the various mice protokols.
Bug fixes here and there, all known PR's closed by this update.

9b2b0822b7 Removed unused #includes of <i386/isa/icu.h> and <i386/isa/icu.h>. icu.h
is only used by the icu support modules and by a few drivers that know
too much about the icu (most only use it to convert `n' to `IRQn').  isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

f0ea07bffb Reduced nesting of #includes in random.h and adjusted isa/random_machdep.c
to match (pc98/random_machdep.c probably requires a similar change).  This
is a problem area for the PC98 merge - all PC98 ifdefs in <machine/*.h> are
kludges to work around incorrect layering.

7d64a7fe80 Added support for TIOCDCDTIMESTAMP (enable/get timestamp of last DCD rise).
Original version by John Hay.

Simplified timestamp code by reading the time exactly when necessary.
This may slow down the interrupt handler with extra calls to microtime(),
but only in bad configurations - the input fifo should normally be
disabled if timestamps on input are being used, since otherwise the
timestamp won't be precisely associated with any particular input event.
The interrupt handler remains slowed down by one test and branch for
each input (and now DCD change) event - avoiding this is not practical
yet.

The simplifications also fixed:
- timestamps for input sometimes being clobbered by output and modem
  status interrupts.
- valid timestamps not being available unless the port is configured with
  vector siointrts.  siointrts no longer exists.
- compiler warnings about siointr* in some configurations.

Simplified timestamp and probe code by depending on recent changes in
microtime() and DELAY() to preserve the interrupt enable flag.

16263f7a8b In getit(), use read_eflags()/write_eflags() to preserve the interrupt
enable flag instead of enable_intr() to restore it to its usual state.
getit() is only called from DELAY() so there is no point in optimising
its speed (this wasn't so clear when it was extern), and using
enable_intr() made it inconvenient to call DELAY() from probes that need
to run with interrupts disabled.

333f7d7bb6 At long last, we know have support for the 3C589 in a FreeBSD release
using the existing files using the existing PCCARD support.  Now that
this is in place I would like to fixup the PCCARD hooks and remove the
if_zp driver.  At this point, we support everything we used to support
*AND MORE* with the PCCARD code.

8ca7c1c4a0 Better code for switching the ethernet transceiver.
My 3C509B-COMBO works fine with the following patch. Switching between
UTP and BNC is quite easy. (Just type 'ifconfig ep0 link1 -link2' or 'ifconifg
ep0 link2 -link1'.)

connectors on my 3C589B and 3C589C ]

2e60812e3a Fix the spl handling. There's still the effect that the timers have
sometimes already been released at the time pcaclose() is called, but
this is now prevented from deadlocking by checking for a running timer
at the start of pca_wait().

8408422768 Add support for NE2000 compatible PCI Ethernet cards. The PCI probe
is enabled by having an "device ed0 at isa? [...]" config line.
The first PCI card will get a unit number one higher than the highest
defined for any ISA card of the ED type, e.g. if ed0 and ed1 are
configured, then the PCI cards will be ed2, ed3, ...

BEWARE: If you have configured your kernel as ed0 with the port address
as assigned by the PCI BIOS, then your card will be found by both the
PCI and ISA probes, and bad things may happen. Make sure to restore
the original port address form the GENERIC kernel for the ed0 device!
