c9bfe68408 move intrhand2_t from isa_device.h to machine/types.h - it's used far more

4c9340d45c Add support for shared interrupts to the kernel. This code is meant
be (eventually) architecture independent. It provides an emulation
of the ISA interrupt registration function register_intr(), but that
function does no longer manipulated the interrupt controller and
interrupt descriptor table, but calls the architecture dependent
function setup_icu() for that purpose.

After the ISA/EISA bus code has been modified to directly call the new
interrupt registartion functions (intr_create() and intr_connect()),
the emulation of register_intr() should be dropped.

The C level interrupt handler function should take a (void*) argument,
and the function pointer type (inthand2_t) should defined in some  other
place than isa_device.h.

This commit is a pre-requisite for the removal of the PCI specific shared
interrupt code.

296bffc9c0 informal discussion between Bruce Evans <bde@zeta.org.au>,

removed all the IPI_INTS code.
made the XFAST_IPI32 code default, renaming Xfastipi32 to Xinvltlb.
cleanup of i386/isa/isa_device.h to eliminate SMP dependancies:
  made the id_irq member of struct isa_device an u_int.
  made the id_drq member of struct isa_device an int.
  removed all other '#ifdefs' concerning SMP & APIC_IO.

fbf8a6b7cb change #if 0 to #ifdef KERNEL since this is pretty important for
smp compiling.  It still leaves dset non-functional on smp kernels, but

bb625c15c9 #if'ed out the '#include "opt_smp.h"' line.
The SMP source was merged into 3.0-current last nite and this broke
the make of sbin/dset.

Should make things work for non-SMP case.

People making SMP kernels will need to edit i386/isa/isa_device.h, re-enabling
'#include "opt_smp.h"'.  People making SMP worlds will have to punt for now...
I'm thinking about the real solution, but for now the goal is to NOT break
the world!

477a642cee Man the liferafts! Here comes the long awaited SMP -> -current merge!
There are various options documented in i386/conf/LINT, there is more to
come over the next few days.

The kernel should run pretty much "as before" without the options to
activate SMP mode.

There are a handful of known "loose ends" that need to be fixed, but
have been put off since the SMP kernel is in a moderately good condition
at the moment.

This commit is the result of the tinkering and testing over the last 14
months by many people.  A special thanks to Steve Passe for implementing
the APIC code!

1dce4e5d60 Add a lock for DMA Channels to prevent two devices from using the same DMA
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

e7451974bb Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:

kern/subr_xxx.c:

2f86936a07 Finished device configuration database work for all ISA devices (except `ze')
and all SCSI devices (except that it's not done quite the way I want).  New
information added includes:

-	A text description of the device
-	A ``state''---unknown, unconfigured, idle, or busy
-	A generic parent device (with support in the m.i. code)
-	An interrupt mask type field (which will hopefully go away) so that
.	  ``doconfig'' can be written

This requires a new version of the `lsdev' program as well (next commit).

if_ed.c, syscons.c:  Set the above flag.  ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)

bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.

isa.c:  Probe devices with the above flag set before the rest.  Reduce the
number of "conflict" messages per device to one.

f0b544e99e Restore the intr_* array variables that were removed in the previous
revision.  They caused redundant redeclaration warnings because I
forgot to declare them as extern and gcc-2.6.0 treats "extern int x[];"
slightly different from "int x[];" (this is probably a bug).  The new
versions will cause RR warnings from gcc-2.4.5 because it does not
understand that the second declaration in "extern int x[]; int x[1];"
is not redundant.  The variables don't actually need to be declared
in a header file because they are used in only one C source file and
one assembler source file, but I want all public variables and
comments about them to be findable by grepping *.h.

8912c0ed61 Bruce Evans' dynamic interrupt support.
/usr/src/sys/i386/isa/clock.c:
	o Garrett's statclock changes.
	o Wire xxxintr, not Vclk.
	o Wire using register_intr(), not setidt().

/usr/src/sys/i386/isa/icu.s:
	o Garrett's statclock changes.
	o Removed unused variable high_imask.
	o Fake int 8 for rtc as well as int 0 for clk.  Required for kernel
	  profiling with statclock, harmless otherwise.

/usr/src/sys/i386/isa/isa.c:
	o Allow isdp->id_irq and other things in *isdp to be changed by
	  probes.  Changing interrupts later requires direct calls to
	  register_intr() and unregister_intr() and more care.
	  ALLOW_CONFLICT_* is brought over from 1.1.5, except
	  ALLOW_CONFLICT_IRQ is not supported.  IRQ conflict checking is
	  delayed until after probing so that drivers can change the IRQ
	  to a free one; real conflicts require more cooperation between
	  drivers to handle.
	o Too many details to list.
	o This file requires splitting and a lot more work.

/usr/src/sys/i386/isa/isa_device.h:
	o Declare more things more completely.

/usr/src/sys/i386/isa/sio.c:
	o Prepare to register interrupt handlers as fast.

/usr/src/sys/i386/isa/vector.s:
	o Generate entry code for 16 fast interrupt handlers and 16 normal
	  interrupt handlers.  Changed some constants to variables:
	  # $unit is now intr_unit[intr].  Type is int.  Someday it should
	    be a cookie suitable for the handler (e.g., a struct com_s for
	    sio).
	  # $handler is now intr_handler[intr].
	  # intrcnt_actv[id_num] is now *intr_countp[intr].  The indirection
	    is required to get a contiguous range of counters for vmstat
	    and so that the drivers depend more in the driver than on the
	    interrupt number (drivers could take turns using an interrupt
	    and the counts would remain correct).  There is a separate
	    counter for each device and for each stray interrupt.  In
	    1.1.5, stray interrupt 7 clobbers the count for device 7 or
	    something worse if there is no device 7 :-(.
	  # mask is now intr_mask[intr] (was already indirect).
	 o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
	   not _VdevU (U = unit).
	 o Removed BUILD_VECTORS stuff.  There's a trace of it left for
	   the string table for vmstat but config now generates the
	   string in one piece because nothing more is required.
	 o Removed old handling of stray interrupts and older comments
	   about it.
