- use more registers when copying
- use hardware to draw the cursor
- use putchar() for horizontal scrolling since byte-wise overlapping copy
ops wouldn't be any faster anyway
#if (defined(SUN4M) && !defined(MSIIEP)) || defined(SUN4D)
to give them the same scope as the definitions in ../sparc/intr.c.
Allows SUN4C-only kernels to compile.
OK mrg
instead of forcing a nul byte afterwards, KASSERT() that the final byte
already is a nul. if there are broken proms... well, we can fix them.
this, plus one more change, allows my SS20 to boot multiuser.
the original ad-audiomp branch notes:
Add MP locking to the audio drivers.
Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe.
The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks.
Welcome to 5.99.57.
rather than sharing them among all zs devices and searching softc
in handlers.
The latter method is derived from ancient sun3 zs driver which tried
to reduce overhead on autovectored interrupts, but nowadays such hack
might cause recursive global locks on modern SMP capable framework.
Fixes "5.99.30 sparc panic during startup" reported by Hauke Fath
on tech-kern@:

and also tested by Jochen Kunz on SS20 with both serial and kbd console.
Ok'ed by mrg@ and dyoung@.
knows it's console and passes the right flags to wskbd, now the wskbd will
not drop off the mux when leaving event mode.
Symptoms: now the keyboard should no longer be dead when leaving X and there
should be no more panics caused by it
I tested this on an SS5 and an SS20, may need some more attention and zs.c
sure could use some cleanup - there are a few differences to sparc64 that
really don't make much sense to me, like not passing console flags to zstty
which sparc64 does but sparc avoids, which caused this problem in the first
place.
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.
passed to child devices even in !(NWSKBD == 0) case so that zs console
functions are actually used rather than the default prom console.
Fixes stray interrupts on MP machines running GENERIC.MP kernel with
zs serial console.
Ok'ed by mrg@.
on SPARCstation-4/5, and emulated by qemu to idle the simulator
when the CPU is idle. Infos about the registers from the linux driver.
Not enabled by default because it can cause some Sparc systems to
hang (so says the linux driver).
Only the CPU idle part implemented at this time; fan speed and
Convenience power outlet management to be added.
Tested on qemu.
for the sun4m timer/counter interrupts. this gets lev10/14 working again
on SMP systems, where those interrupts started taking the kernel lock and
hanging...
in sparc/amd7930intr.s and sparc/bsd_fdintr.s until they are
rewritten to adapt new MI softint(9) API.
No particular comments on PR port-sparc/42192, but
this fixes timeout problem on floppy access on my SPARCstation 1+.
XXX: floppy support on sun4m seems to have another problem (data overrun).
struct timeval passed to todr_gettime(9) and todr_settime(9).
We no longer have an ancient and volatile struct timeval `time'
global since we have switched to MI timercounter(9) on all port.
XXX1: some of these RTC drivers still assume 32bit time_t
XXX2: some of these should be rewritten to use todr_[gs]ettime_ymdhms()
XXX3: todr(9) man page doesn't mention todr_[gs]ettime_ymdhms()
They are derived from 4.4BSD/sparc and have been there since initial import
of NetBSD/sparc in 1993, but the struct sbusdev is almost unused for years,
nothing calls sbusreset(), and all (*sd->sd_reset)() functions look bogus.
Suggested by mrg@ and martin@, and tested on SS1+ and SS20.
XXX This should be done as part of an overall plan to support
power management and device detachment. However, in order to do
that, I would first have to invent sbus_intr_disestablish(). This
is being done at this time in order to aid in the effort to eliminate
shutdownhook_establish().
This was based on the sys/arch/sparc64/fd.c change. Thanks to jdc@
for testing this version.
- finally add my copyright, almost 3 year after the fact
- remove a comment that never applied to the NetBSD port of this driver,
only the OpenBSD version
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>
register com_cleanup() as the shutdown hook.
Add a generic suspend routine. Suspend and resume com@isa.
Protect against dereferencing a NULL softc in comioctl().
Destroy both a mutex and a callout in com_detach().
Cosmetic: use aprint_*_dev(). Use PMF_FN_ARGS, PMF_FN_PROTO.
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).
sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.
The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).
Update all users and documentation to reflect these changes.
