cgd cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).

matt 9169d99f2a Don't pass booted_* to findroot/getdevice, access them via the globals.
Also, make findroot static.  This eliminates unneeded clearing of them
and make their use consistent among the ports.
2000-06-01 15:38:20 +00:00
matt c9aff328d9 Make booted_device global (and booted_parition for consitency).
Eliminate it from header files and other extern definitions.

cgd 47449a63d2 kill __P in these files. (I had to look at them anyway with an eye for
adding some protos... and adding them with __P seems wrong, but mixing
__P and not __P in the same file seems wrong too, so...)

thorpej 8c2d00aaeb Add a comment about needing to initialize p_cpu when multiple
processors are supported.

thorpej b3b7588160 Don't use sleep() and callouts; just use tsleep(). 2000-05-27 04:42:14 +00:00
thorpej a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

thorpej 8964c35eca Introduce a new process state distinct from SRUN called SONPROC
which indicates that the process is actually running on a
processor.  Test against SONPROC as appropriate rather than
combinations of SRUN and curproc.  Update all context switch code
to properly set SONPROC when the process becomes the current
process on the CPU.

thorpej 463931b3ba Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

hubertf 9f48bba3ae Add "install" target, so "make install" after building the kernel
does something useful.  The target can be redefined by putting a
install-kernel-${MACHINE_NAME} target that fits your needs into
/etc/mk.conf.

thorpej 6a33c86623 HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also,
make the use of -Wno-uninitialized explicit, don't rely on a compiler
hack to do it for us.

thorpej f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

thorpej 0cde36f780 Carve off the ISA configuration bits from the floppy driver. Driver is
still ISA-specific, but we can attach ISA instances with different
configuration mechanisms now.

ws b7570cae85 Update several ports to at least work again without IPKDB
after the update of that.
Sorry for breaking this with my last changes :-(.
Fixes PR#9671 by Lennart Augustsson.

thorpej b667a5a357 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

oster 1bad2e1909 Add the RAIDframe device major to the machine-dependent config files
so that the right entries get added to dev_name2blk[].  Needed for / on RAID.
(Whoops!  I missed checking these in when adding the RAID_AUTOCONFIG stuff.)

thorpej a183d34f04 - Implement cnbell() -- ring the console bell. The cn_bell entrypoint
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

simonb 4eb55e447c Do the "<space><tab>" thing with the RAID_AUTOCONFIG option. 2000-02-29 06:32:20 +00:00
oster d9c47013b2 Defopt 'RAID_AUTOCONFIG'. Adding 'options RAID_AUTOCONFIG' turns on
the component auto-detection and auto-configuration of RAID sets.
Also, add "#options RAID_AUTOCONFIG" to the GENERIC config files.

thorpej 52a2804a5c Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.

thorpej fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple
active partitions were on a single spindle.  Add a b_rawblkno member to
struct buf which contains the non-partition-relative block number to sort
by.
