2c362dc181 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.

12ec611ec6 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.

959a234634 Set p->p_switchtime to switchtime instead of to the current time in
fork_trampoline() if switchtime is valid.  This fixes not accounting
for the time between the previous context switch and and the current
time (when the forked child starts up here) in most cases - the time
is now counted in the child's runtime.  I think it actually fixes
all cases, and switchtime is always valid here, since there must have
been a context switch just before the forked child starts up.  Some
code should be removed if this is correct.  The check that switchtime
is valid sometimes gives a false negative because the check isn't
correct until the after the first context switch after the system
has been up for >= 1 second.

39d6cd0751 Stop physical DMA for the non-auto case in isa_dmadone(). This fixes a
small part of a bug suite beginning in the SLICE probes but mostly in the
floppy driver.  This is a quick fix: the auto case shouldn't be special;
DMA should also be stopped in isa_dma_release(); isa_dmastop() probably
shouldn't exist; common DMA registers should not be accessed without
locking.

7466f92c1a 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.

caused remarkably few problems in C code, but the inline asm here

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

0262543b5f There is no such thing any more as "struct bdevsw".
There is only cdevsw (which should be renamed in a later edit to deventry

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.

5ffa52e68e Add workaround to allow the FreeBSD boot block to work on
Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
on having a short jump and nop as the first instructions in the
boot sector code. The prevailing theory is that the BIOS is doing
some sort of boot sector virus detection and refusing to run any
boot block that doesn't start with the same instruction sequence as
MS-DOG boot sector code. If this is the case, it would be nice if it
actually printed an error message to this effect instead of just
saying 'FAILED.'

This workaround has no effect on the boot sector code other than to
increase its size by three bytes.

406115eeb3 These are a selection of small problems and annoyances with the netboot
code. Apart from the first one, none really affect typical configurations
but are nevertheless unnecessary limitations. We use netbooted PCs as
student X-terminals and all of the below fixes have been useful. Apologies
for including them all in one PR, but some are just too silly or trivial
to send on their own!

a)     Newer SMC cards have hardware addresses starting with 00:E0.
      Netboot compares the MAC address with 00:00:C0 to determine
      if it is a WD/SMC card, so it fails to detect these.

b)     Netboot is unable to boot kzipped kernels, as it assumes that
      the kernel load address is 0x100000.

c)     Users can abort the booting process and enter arbitrary network
      addresses, or boot from a floppy disk. This can be a problem when
      netbooted machines are used in a student environment.

d)     It is not possible to set all options via bootp. For example there
      is no way to remotely force a client to boot from disk. With both
      SECURE_BOOT(patch below) and NO_TFTP defined, short of unplugging
      the eprom there is no way at all to get the client to boot locally.
      A generic solution is to allow complete netboot commands to be sent
      using bootp lines such as:
	      :T132="diskboot":
e)     The last character of netboot command names is not checked. You
      can type 'iz 10.0.0.1' and it will be interpreted as 'ip'. This
      is only important if you try to add a new command which is the
      same as an existing one except for the last character.

f)     We have a configuration where multiple servers are willing to serve
      a diskless client. The tftp config file, or the bootptab entry on
      each server must specify the root and swap filesystems as 'ip:/fs'
      even though 'ip' will usually be the responding server's IP address.
      It would be nice if netboot could automatically prepend the server's
      IP address to an entry specified as just '/fs', so that multiple
      servers can use the same tftp or bootp configuration files. Admittedly
      this is hardly a major problem!

    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.

0d80f93df9 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.

Maintain process "on-cpu" time as 64 bits of microseconds to avoid

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.

a4775d632f Missing parens caused cpu features not to be printed for cyrix >= M2/MX.
Althought the comments say the datasheet doesn't list the device ID
registers on the M2/MX, they seem to be there and quite alive.
(It's interesting to note that the M2/MX calls itself a 686 class cpu but
 is missing a heck of a lot of features, including VME, PGE, PSE, etc)

cf73abacf6 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.

Remove some unneeded manipulation of tpr register in mplock.s.

Adjust code in mplock.s to be aware of variables on the stack being
destroyed by MPgetlock if GRAB_LOPRIO is defined.

4347025be3 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.

ec73ba31ec Some of newer PC-98 may cause "Windows Protection Fault" when booting
Windows 95 after rebooting FreeBSD without power off.  In PC-98
system, reboot mode is set via I/O port 0x37 in cpu_reset(), and
accessing of this port is the reason of the problem.  To avnoid the
fault, current status of reboot mode should be checked before
accessing the I/O port.

53cc68b743 Backed out previous commit. It is invalid to call d_ioctl() on
possibly non-open devices, and we don't want to restrict dumping
to swap devices anwyay.  It is especially invalid to call d_ioctl()
in non-process context for panics.  d_psize() can be called on
non-open devices, at least on non-SLICED ones that support d_dump(),
and setdumpdev() has depended on this for a long time although it
is probably wrong, but even d_psize() can't be called in non-process
context - that's why dumpsys() depends on previously computed values
although these values may be stale.  The historical restriction to
devices with dkpart(dev) == SWAP_PART should go away.
