thorpej 72a24b4eae Add an align argument to uvm_map() and some callers of that
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

thorpej 58e7a6954b Add spllock(). See spl(9) for details. 2000-08-22 19:46:26 +00:00
thorpej 23a7f255d4 Make sure we provide splsched() as described in spl(9). 2000-08-21 02:06:31 +00:00
itojun 85dda25e94 move "options PULLDOWN_TEST" into sys/sys/mbuf.h (in #ifdef _KERNEL),
as it is no wthe default setting for everyone.

the reason we still use the name "PULLDOWN_TEST" while it is now default:
kame code sharing.

tshiozak 51a53de0d5 Preparation for the future introduction of multibyte locale.
- MB_LEN_MAX is increased to 32.
 - To ensure binary compatibility for old executables
   under multibyte locale, versioned setlocale is added.
 - __mb_len_cur definision is added in setlocale.c
   and enable it in stdlib.h .
   It is also important for multibyte locale stuffs,
   but I just forgot.

I've tried hard to find also various usage() messages and remove the
appropriate flag from there as well, hopefully all occurences are covered.

cgd a5c13f9ad4 Kwality control:
* put #includes of opt headers and headers to get protos used by
  net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than
  in netisr_dispatch.h itself, and potentially nowhere, respectively).
* require netisr.h to be included before netisr_dispatch.h.
* minor additional cleanup of both netisr.h and netisr_dispatch.h.
* clean up uses to remove now-unnecessary header file inclusions, and
  local prototypes of the fns.
* convert netisr dispatch implementations which didn't use
  netisr_dispatch.h (pc532) to use it.

itojun d738f90fd7 raise MSIZE from 128 to 256.
- for sizeof(void *) == 8 arch, this is mandatory.  MHLEN is too small
  already (less than 80) and there are chances for unwanted packet loss due
  to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
  (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
  extension header)

portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

thorpej 7a5ce477cb When allocating new PT pages during early bootstrap (i.e. before
pmap_init() has finished), make sure to zero them.

thorpej 8871d8563a Add a comment on single-processor systems about p_cpu being initialized
by fork1().
2000-05-31 05:06:43 +00:00
nisimura 0e80e9cd4b Minor comment adjustments. cpu_switch has an argument of struct proc *. 2000-05-31 01:46:15 +00:00
thorpej e03e9e8086 Rather than starting init and creating kthreads by forking and then
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1().  In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.

This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.
2000-05-28 05:48:59 +00:00
sommerfeld 40339b39f9 Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than
p->p_tracep, since the various ktr* function need curproc anyway.

 - Add curproc as a parameter to mi_switch() since all callers had it
handy anyway.

 - Add a second proc argument for inferior() since callers all had
curproc handy.

Also, miscellaneous cleanups in ktrace:

 - ktrace now always uses file-based, rather than vnode-based I/O
(simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD.
Do non-blocking I/O, and yield a finite number of times when receiving
EWOULDBLOCK before giving up.

 - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.

 - simplify interface to ktrwrite()

cgd 5f23f3b392 Fix typo: 68681, not 68881. (I'm a UART, Jim, not an FPU!!!) 2000-05-26 23:03:18 +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.

jhawk 8e44b27348 Rename the machine-specific stack trace printing functions
from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).

Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.

Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].

Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.

jhawk 285fe9436f In callback for db_printsym(), use db_printf() rather than printf() [oops]. 2000-05-26 02:10:18 +00:00
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.
2000-05-26 00:36:42 +00:00
jhawk f3528d725d Interface change: db_printsym() takes a third argument, pr, a function
pointer indicating how to print the symbol. This allows db_printsym()
to called in places where db_printf() is not an appropriate output
function.

While straightforward, apologies in advance if I've introduced any minor
syntax errors; I was unable to test compilation this on all the affected
platforms.

thorpej 7f4eca2d94 Use preempt(), not an open-coded equivalent (which won't be
equivalent for long).
2000-05-24 17:28:05 +00:00
thorpej 071aed40ac A foolish consistency; most parts of the kernel use bp->b_data, so
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.
2000-05-19 18:54:22 +00:00
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.
2000-05-09 00:56:21 +00:00
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.
2000-05-09 00:32:19 +00:00
thorpej 855b79db92 Let each platform typedef the new __cpu_simple_lock_t, which should
be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.
2000-05-02 04:41:04 +00:00
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>.
