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 d37f3bd4ee Use UVM_PGA_ZERO in pmap_alloc_ptp(). 2000-04-10 06:34:11 +00:00
jdolecek cef3c93f82 Switch to MI ns_cksum.c - the MD ns_cksum.c is equivalent to it 
(modulo some u_intX_t vs. u_char type usage). In particular, the
MD version didn't contain any MD code.

thorpej 2bc5adb20e Instead of checking vm_physmem[<physseg>].pgs to determine if 
uvm_page_init() has completed, add a boolean uvm.page_init_done,
and test against that.  Use this same boolean (rather than
pmap_initialized) in pmap_growkernel() to determine if we are
being called via uvm_page_init() to grow the kernel address space.

This fixes a problem on some i386 configurations where pmap_init()
itself was needing to have the kernel page table grown, and since
pmap_initialized was not yet set to TRUE, pmap_growkernel() was
choosing the wrong code path.

Fix tested by Havard Eidnes.

msaitoh 35ba37f2f7 fix the sci[f]cninit() bugs to work both SCI and SCIF at the same time. 2000-03-27 16:24:08 +00:00
kleink 230876cf26 Merge parts of chs-ubc2 into the trunk: 
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

thorpej 7b918b4088 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.
