This is the kernel part (userland to follow soon) of the latest (and
very probably last) release (version 0.96) of ISDN4BSD. ISDN4BSD has a
homepage at http://www.freebsd-support.de/i4b/.
It gives the user various ways to use the isdn connection: raw data (via
the i4brbch "raw b-channel" device), ppp (via the isp "isdn PPP" device),
voice/answering machine (the i4btel "telephone" device) and ip over isdn
(the ipr device, "IP over raw ISDN").
Supported are a bunch of common and older cards, more to be added soon
after some cleanup. Currently only the european E-DSS1 variant of the
ISDN D channel protocol is supported.

* move all exec-type specific information from struct emul to execsw[] and
provide single struct emul per emulation
* elf:
- kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
per emulation and contains pointer to respective probe function
- interp is allocated via MALLOC() rather than on stack
- elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
part of appropriate execsw[] entry
* constify couple of structures
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

How we ever got along without this for so long is beyond me.

* put #includes of opt headers and headers to get protos used by
net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than
in netisr_dispatch.h itself, and potentially nowhere, respectively).
* require netisr.h to be included before netisr_dispatch.h.
* minor additional cleanup of both netisr.h and netisr_dispatch.h.

"off_t" and the return value is a "paddr_t" to allow mappings

- for bold characters, only blit the leftmost ftwidth pixels per character
cell row. The rightmost row which used to be printed would have been
overwritten formerly by the next character on sequential output, so no
visible change will result most of the time.
This fixes two problems:
* USE_C_BFOPS (which only works for 8 pixel wide fonts) blits the same
for bold characters now... it used to print the rightmost 8 pixel columns
of the bold-smeared characters
* we no longer need a reserved 1 pixel column at the right end of the screen.
That is, a 640x400 screen will hold 80x50 charactes with the 8x8 font.
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1(). In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.
This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.
- Change ktrace interface to pass in the current process, rather than
p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it
handy anyway.
- Add a second proc argument for inferior() since callers all had
curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O
(simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD.
Do non-blocking I/O, and yield a finite number of times when receiving
EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()
state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.
- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.
which indicates that the process is actually running on a
processor. Test against SONPROC as appropriate rather than
combinations of SRUN and curproc. Update all context switch code
to properly set SONPROC when the process becomes the current
process on the CPU.
change these from bp->b_un.b_addr to bp->b_data, as well. This also
allows us more flexibility to experiment with other data buffer types

contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
as sizeof(struct device) when amiga switched to new config, and recent
additions of callout structures and a long missing struct device to the
soft structure resulted in kernel panics when attempting to open the builtin
serial port. The callout structure initialization was clearing the serial
port softc data! Fixed by using sizeof(struct par_softc).
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
make them type-generic, which is necessary i.e. to operate on file offsets
without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
integral type (paddr_t, vaddr_t).
Originally done by Chuck Silvers, updated by myself.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.

(Whoops! I missed checking these in when adding the RAID_AUTOCONFIG stuff.)
on an A1200 yet. Configuration of wdc/atapi in GENERIC is currently
commented out to prevent the suprise of an IDE drive changing from sd0
to wd0 (and the first real SCSI drive changing from sd1/sd1 to sd0).
Note: enabling these will cause disk device renumbering if any IDE were
present (i.e. if sd0 was IDE drive 0, that drive will become wd0 and sd0
will be the first real SCSI drive.
Add a byte-swapping access_method array for use with MI wdc driver.

This is not strictly necessary, as
- at least for the Ricoh chip in the A3000 and A4000, as those chips' Y10
registers happily continue to count up from 0xA if manually incremented
past 0x9.
- the Amiga ROMs and "setclock" commands seem to interpret 0xA 0x? like
200?, etc.
However,
- the Amiga setclock writes the modulo 10 value into the chips
- the chip docs of both chips, including the Y2K information of their
manufacturers, only refer to the range 0-9
- the chips increment from 9 to 0
So we better conform to this, to avoid unpleasant surprises.
"To fully support self-modifying code in any situation, it is imperative that
a CPUSHA intrcution is executed before the execution of the first self-modified
instruction. The CPUSHA instruction has the effect of ensuring that there is
no stale data iin memory, the pipeline is flushed, and instruction prefetches
are repeated and taken from external memory."
I verified that this is the only way (I can think of) to make the sigtramp
regression test work on 68040. doing cpushl dc; cinvl ic; over the affected
address range, then nop (to synchronize the pipeline) is not enough; apparently
the nop does not FLUSH the pipeline and prefetch...
Note that the 68060 UM has copied the above cited passage, but in fact this is
not true. This might be connected to the fact that the 68060 does ensure
memory access order under most conditions.

IPsec items are commented out as well, though we can enable "options IPSEC"

This fixes a problem with using the "rnd" pseudo-device from within

- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that. INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now). This will eventually
change now these maps are locked, as well.

in the page being collected.
