pk 25e37f3b97 In addition to the spinlock, use the lockmgr() to serialize access to
the back-end page allocator. This allows the back-end to sleep since we
now relinquish the spin lock after acquiring the long-term lock.

thorpej 73aefe65bc If MULTIPROCESSOR, add a spin lock around the kernel printf (in the
appropriate places).  This makes debugging messages work a LOT better
on my multiprocessor Alpha.

operations.

thorpej 911fd86e93 Regen; signal changes. (mycroft must have forgotten to commit this) 1998-09-11 22:37:53 +00:00

mycroft fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

pk 3718fc4aa7 Allow the result of an extent allocation to be congruous to an arbitrary
number modulo the given alignment.
To do this the function extent_alloc_subregion() takes an additional `skew'
parameter.  For compatibility's sake, this function has been renamed to
extent_alloc_subregion1().

thorpej 93ea1946f0 Implement a new kernel thread, the "reaper", which performs the task
of freeing the VM resources once a process has exited.  A valid thread
must do this work, as doing so may block in a multi-processor environment.
1998-09-08 23:57:58 +00:00
thorpej 970e60efb8 - Use proclists[], rather than checking allproc and zombproc explicitly.
- Add some comments about locking.
1998-09-08 23:50:13 +00:00
thorpej 4edbfb00a8 - Add a new proclist, deadproc, which holds dead-but-not-yet-zombie
processes.
- Create a new data structure, the proclist_desc, which contains a
  pointer to a proclist, and eventually, a pointer to the lock for that
  proclist.  Declare a static array of proclist_descs, proclists[],
  consisting of allproc, deadproc, and zombproc.

thorpej 77ecf8273e Use the pool allocator and "nointr" pool page allocator for name cache entries.
The only benefit this provides is that we don't use kmem_map to map the memory
used for name cache entries (though, this is a 13 virtual page savings on my
PPro) since vnodes are never freed (they have their own freelist).

thorpej 830ea34819 Use the pool allocator and "nointr" pool page allocator for vnodes. The

used for vnodes (though, this is a 30 virtual page savings on my PPro)
since vnodes are never freed (they have their own freelist).
