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

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

Kazutaka YOKOTA 88a5f0cca7 1. Reorganized screen saver related code so that both the LKM screen
saver and splash screen can all work properly with syscons.  Note that
the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it
requires additional code from msmith.

- Reorganized the splash screen code to match the latest development
  in this area.
- Delay screen switch in `switch_scr()' until the screen saver is
  stopped, if one is running,
- Start the screen saver immediately, if any, when the `saver' key is
  pressed. (There will be another commit for `kbdcontrol' to support
  this keyword in the keymap file.)
- Do not always stop the screen saver when mouse-related ioctls
  are called.  Stop it only if the mouse is moved or buttons are
  clicked; don't stop it if any other mouse ioctls are called.

2. Added provision to write userland screen savers.  (Contact me if you
are interested in writing one.)

- Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to
  support userland screen savers.

3. Some code clean-ups.

Jonathan Lemon f88a03565a Add wrappers for i386_*_ioperm, i386_vm86 so userland code does

Bruce Evans 88bf59fcda Don't pretend to support ix86's with 16-bit ints by using longs just to
ensure 32-bit variables.  Doing so mainly bogotified some printf formats.

Bruce Evans 00be8601cd Don't pretend to support ix86's with 16-bit ints by using longs
just to ensure 32-bit variables.  Doing so broke and/or pessimized
i386's with 64-bit longs (unnecessary use of 64-bit variables
caused remarkably few problems in C code, but the inline asm here
tended to fail because there are no 64-bit registers).  Since the
interfaces here are very machine-dependent and shouldn't be used
outside of the kernel, use a standard types of "known" width instead
of fixed-width types.

Changed all quad_t's to u_int64_t's.  quad_t isn't standard, and
using signed types for 64-bit registers was bogus (but made no
difference).

Bruce Evans 9d508ad2d9 Don't pretend to support ix86's with 16-bit ints by using longs just
to ensure 32-bit variables.  Doing so broke i386's with 64-bit
longs.  Use fixed-size integral types instead of plain ints, shorts,
chars and pointers since the bootinfo struct layout is a binary
interface.  The boot blocks could reasonably be implemented using
16-bit code.

Bruce Evans 930a642372 Oops, fptrint_t still needs to be declared in <machine/profile.h> in the
!KERNEL case.  The kludge to get it declared in libc/gmon/mcount.c wasn't
sufficient because fptrint_t is used in <sys/gmon.h>.
1998-07-10 09:26:41 +00:00
Bruce Evans 2e480d34aa Added a kernel-only typedef (ptrint_t) giving an integral type that is
least unsuitable for holding an object pointer.  This should have been
used to fix warnings about casts between pointers and ints on alphas.

Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>.  Kludged libc/gmon/mcount.c so that it can
still see this typedef.

Bruce Evans 316bbd5c6f Converted add_interrupt_randomness() to take a `void *' arg. Rewrote
mmioctl() to fix hundreds of style bugs and a few error handling bugs
(don't check for superuser privilege for inappropriate ioctls, don't
check the input arg for the output-only MEM_RETURNIRQ ioctl, and don't
return EPERM for null changes).
1998-06-21 11:33:32 +00:00
Bruce Evans 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).
1998-06-18 15:32:09 +00:00
Bruce Evans 084d9853ca Don't declare isa device structs or isa interrupt handlers in <sys/conf>,
and don't depend on them being declared there.  This will cause lots of
warnings for a few minutes until config is updated.  Interrupt handlers
should never have been configured by config, and the machine generated
declarations get in the way of changing the arg type from int to void *.

    The patch supports using the X10 Mouse Remote in both stand-alone and
pass-through configurations, so you can plug your mouse and remote into the
same serial port, use the mouse for X, and use the remote for other apps
like Fxtv. For instance, we can now control fxtv via the remote control
just like a TV : change channels, mute, increase volume, zoom video,
freeze frame 8)

     The mouse events are channeled through the syscons/sysmouse I/F like
normal, and the remote buttons are "syphoned off" to a UNIX-domain stream
socket (defined as _PATH_MOUSEREMOTE in <machine/mouse.h>) for a
remote-aware app to grab and use.

Bruce Evans f0c2a198e7 Removed LOCORE ifdef. This header isn't used for locore stuff.
Use uoff_t instead of `unsigned long long' for unsigned offsets.

Bruce Evans 54968d29c0 Define 64-bit types in terms of __int64_t and __uint64_t.
Define an unsigned version of off_t (uoff_t) if KERNEL is defined.
This is useful for micro-optimizing expressions involving off_t's
where you know that the values are non-negative but the compiler
doesn't know it.

Fixed a gratuitous ANSIism.

Bruce Evans 23adf828d5 Added typedefs for __int64_t and __uint64_t. These will be used to avoid
explicit use of `[unsigned] long long' and `[u]quad_t'.

two commits.  Improved some comments.  The comments should be elswhere

Poul-Henning Kamp e796e00de3 Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.
Clean up (or if antipodic: down) some of the msgbuf stuff.

Use an inline function rather than a macro for timecounter delta.

Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.

Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()

This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

WARNING:  Programs which muck about with struct proc in userland
will have to be fixed.

Tor Egge 5d183e9691 Change simple lock handling to not depend upon having a local apic
available.  The per-cpu variable ss_tpr has been replaced by ss_eflags.
This reduced the number of interrupts sent to the wrong CPU, due to
the cpu having the global lock being inside a critical region.

Tor Egge 2f1e70693d Add forwarding of roundrobin to other cpus. This gives a more regular
update of cpu usage as shown by top when one process is cpu bound
(no system calls) while the system is otherwise idle (except for top).

Don't attempt to switch to the BSP in boot().  If the system was idle when
an interrupt caused a panic, this won't work.  Instead, switch to the BSP
in cpu_reset.

Remove some spurious forward_statclock/forward_hardclock warnings.
