7095ee912b * Fix a couple of places in the device pager where an address was
truncated to 32 bits.
* Change the calling convention of the device mmap entry point to
  pass a vm_offset_t instead of an int for the offset allowing
  devices with a larger memory map than (1<<32) to be supported
  on the alpha (/dev/mem is one such).

These changes are required to allow the X server to mmap the various
I/O regions used for device port and memory access on the alpha.

6cde7a165f Fixed two potentially serious classes of bugs:
1) The vnode pager wasn't properly tracking the file size due to
   "size" being page rounded in some cases and not in others.
   This sometimes resulted in corrupted files. First noticed by
   Terry Lambert.
   Fixed by changing the "size" pager_alloc parameter to be a 64bit
   byte value (as opposed to a 32bit page index) and changing the
   pagers and their callers to deal with this properly.
2) Fixed a bogus type cast in round_page() and trunc_page() that
   caused some 64bit offsets and sizes to be scrambled. Removing
   the cast required adding casts at a few dozen callers.
   There may be problems with other bogus casts in close-by
   macros. A quick check seemed to indicate that those were okay,
   however.

DEB macro). There are probably quite a few other messages that warrant
a similar treatment, and many more that should be converted to plain

that I think of it, same goes for the CAM code (e.g. the famed "tagged

The VESA support code requires vm86 support. Make sure your kernel

        options "VM86"
If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
        options "VESA"

The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600

The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.

vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'.  When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

b63b587cb3 A better fix for kern/7144:
The check for dropping unicast packets not sent to our ethernet
address is after the bpf tap, but not conditioned on it.  All packets
received should get handed to bpf, and unicast packets not to us (mac)
should get dropped whether or not there is a bpf listener.  I believe
that the common optimization that the interface is in hw promisc mode
iff there is a bpf listener is in general wrong, but more frequently
so on wavelans.

I think Max's fix makes bpf listeners not see unicast packets sent to
others, but I'm not sure.

One can argue that checking on MOD_ENAL is wrong, but the code only
drops packets that shouldn't be received.  The correctness condition
is that it be run whenever unicast packets without our mac address can
be received.

I don't have access to a real VT220 to verify this against.
However, I'm committing the patch in `good faith' because
(a) getting hold of a real VT220 is going to be increasingly difficult
    the longer the PR sits around,
(b) some one was troubled enough to in a PR and
(c) the fix is minor and has no other implications.

 - ieee1284 infrastructure added, including parallel-port PnP
 - port microsequencer added, for scripting the sort of port I/O
   that is common with parallel devices without endless calls up and down

 - improved bus ownership behaviour among the ppbus-using drivers.
 - improved I/O chipset feature detection

The vpo driver is now implemented using the microsequencer, leading to

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

- 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

- 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.

34e9dea435 Added a flags arg to dsopen() and updated drivers. The DSO_ONESLICE
and DSO_NOLABELS flags prevent searching for slices and labels
respectively.  Current drivers don't set these flags.  When
DSO_NOLABELS is set, the in-core label for the whole disk is cloned
to create an in-core label for each slice.  This gives the correct
result (a good in-core label for the compatibility slice) if
DSO_ONESLICE is set or only one slice is found, but usually gives
broken labels otherwise, so DSO_ONESLICE should be set if DSO_NOLABELS
is set.

5c1a1eae83 Fixed error handling:
- Call isa_dmadone() whenever necessary to stop DMA and/or free bounce
  buffers.  Undead DMA corrupted the malloc freelist fairly consistently
  in the following configuration: SLICE kernel, 2 floppy drives, no disk
  in fd0, disk in fd1.
- Don't call fdc_reset() from fd_timeout().  Doing so gave an "extra"
  interrupt which was usually misinterpreted as being for completion
  of the next FDC command; the interrupt for completion of the next
  FDC command was then usually misinterpreted...  There were further
  complications for interrupts latched by the soft-spl mechanism so
  that they were delivered after all the h/w interrupts went away.
  This caused at least wrong head settle delays and may be why the
  FreeBSD floppy driver seems to munch floppies more than most floppy
  drivers.  The reset was unnecessary anyway in cases that didn't have
  the bug described next, since is was repeated a little later for
  the IOTIMEDOUT state.  The state machine has complications to handle
  resets correctly, so just use it.
- Don't call retrier() from fd_timeout().  The IOTIMEDOUT state needs
  to be processed next, and it isn't valid to set to that state if
  retrier() has aborted the current transfer.  Doing so caused null
  pointer panics after the previous bug was fixed.

Improved error handling:
- If an i/o is aborted, arrange to reset in the state machine before
  doing the next i/o.  New fdc flag for this.  This fixes spurious
  warnings and lengthy busy-waiting for the next i/o.
- Split STARTRECAL into RESETCOMPLETE and STARTRECAL and only check
  for the results from reset if we actually reset.  This fixes spurious
  warnings for other paths to STARTRECAL.  [Oops, it may break reset
  handling for motor-off resets.]

Cleanups in fd_timeout():
- Renamed to fd_iotimeout() to make it clearer that it is only used
  for i/o.
- Don't handle the bp == 0 case.  This case can't happen for i/o.
- Don't check for controller-busy.  We know it must be.
- Don't print anything.  retrier() already prints too much for normal
  errors.
- Fudge the state differently so that the state machine advances
  fdc->retry and the status is invalid (perhaps this should fudge a
  valid state like the one for WP).
- Style fixes.

small part of a bug suite beginning in the SLICE probes but mostly in the

DMA should also be stopped in isa_dma_release(); isa_dmastop() probably
shouldn't exist; common DMA registers should not be accessed without
locking.

e5d7d24361 Fixed error handling after a seek error that can't happen. When the
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case.  This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested.  The fix is simply to arrange to reset the state
machine.

Corruption of the buffer queue seems to only have been a problem in the
floppy driver.  Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order.  Dequeueing breaks it anyway.

cdevsw entries.  The bdevsw[] table stiff exists and is a second pointer
to the cdevsw entry of the device. it's major is in d_bmaj rather than
d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).

rawread()/rawwrite() went away as part of this though it's not strictly
the same  patch, just that it involves all the same lines in the drivers.

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 *.

eca52014bd Don't log "unexpected" events on never-opened devices. Events left
over from the probe are now expected for incompatible UARTs that
deliver IRQs as a strobe (low) instead of a level (high).

Discard events on going-away devices too.  Endless loops may have
been possible when an active pccard was removed.

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.

12e1ed28e2 Force success of the probe (after doing it as before except in one
miscconfigured case) if the port is the console.  This fixes several
bugs:
- if all sioprobe()s failed, then the console driver followed null
  pointers in cdevsw[].
- if the sioprobe() for the console failed but another sioprobe()
  succeeded, then init hung early when the console couldn't be
  opened.
- it was silly for the console to not be there after printing boot
  messages on it.
Bugs introduced by this are hopefully no worse than old ones caused
by forcing the success of the `cn' level probe.

Only complain about an irq mismatch in the probe if the configured
irq doesn't become active, and then print the bitmap of irqs that
became active (including clock irqs) instead of just the first
(not including clock irqs).

cd55b8f46c Converted the ICU-level interrupt tests (3, 5 and 8) in sioprobe() into
a test of the irq number, and made failure of this test non-fatal.
Removed related unused complications for the APIC_IO case.  Removed the
no-test3 flag.

Deverbosified the failure messages for the other tests.  Removed the
per-port verbose flag - just use the general verbose flag.

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.

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.
