da653c6148 Start using the new SWI registration system instead of hardwiring everything. 1998-09-26 14:25:32 +00:00

18c5a6c435 Implemented dynamic registration of software interrupt handlers. Not
used yet.

Use dummy SWI handlers to avoid some checks for null pointers.

a23d65bfc8 Cast pointers to uintptr_t/intptr_t instead of to u_long/long,
respectively.  Most of the longs should probably have been
u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.

9a2daf9190 Changed the type of an isa/general interrupt handler to take a
`void *' arg.  Fixed or hid most of the resulting type mismatches.
Handlers can now be updated locally (except for reworking their
global declarations in isa_device.h).

3900ddb2dc Only build this on i386 for now. I may use it for the alpha later but
currently it doesn't compile.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

cfa5673efd Move include of <machine/ipl.h> inside ifndef SMP where it is used, to
avoid getting 'unused include file' warnings in the SMP case.

fd35ecc322 - Hide the 'device doesn't supported shared interrupts' code behind
bootverbose, since the older register_intr() code didn't print out
  anything, and the laptop support will cause lots of these un-necessary
  messages.

77625cfe0b Moved splq() to isa/ipl_funcs.c for SMP only.
This is in preperation for moving all cpl accesses behind a critical region lock.

0c514a25a0 The defines INTR_FAST and INTR_EXCL are part of the public interface. The
previous commit made them private which broke things.

683523378c Move interrupt handling code from isa.c to a new file. This should make
isa.c (slightly) more portable and will make my life developing the really
portable version much easier.

8c046d14dc Move "typedef struct intrec {} intrec" from sys/interrupt.h to kern_intr.c
since that's the only place that it's used.

425f9fda52 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 theISA/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.
