ad 9b4d249497 Avoid recursive mutex_enter() when the system is low on KVA. 
Should fix crash reported by riz on current-users.
 2008-11-11 16:13:03 +00:00
ad 1ec58d56ef - Rename cpu_lookup_byindex() to cpu_lookup(). The hardware ID isn't of 
interest to MI code. No functional change.
- Change /dev/cpu to operate on cpu index, not hardware ID. Now cpuctl
  shouldn't print confused output.

yamt e4fb48bcaf pool_do_put: fix a pool corruption bug discovered by 
the recent exec_pool changes.
 2008-07-09 02:43:53 +00:00
yamt 03bb7555b4 fix pool corruption bugs in subr_pool.c 1.162. 2008-07-07 12:27:19 +00:00
ad 6c6c91b240 Move an assignment later. 2008-07-04 16:41:00 +00:00
ad 46587f3717 - Keep cache locked while allocating a cache group - later we might want 
to automatically tune the group sizes at run time.
- Fix broken assertion.
- Avoid another test+branch.
 2008-07-04 16:38:59 +00:00
ad 9d573e640e Remove a bunch of conditional branches from the pool_cache fast path. 2008-07-04 13:28:08 +00:00
ad e10320350c Use __noinline. 2008-05-31 13:31:25 +00:00
martin ce099b4099 Remove clause 3 and 4 from TNF licenses 2008-04-28 20:22:51 +00:00
ad 4c7ba24481 Add MI code to support in-kernel preemption. Preemption is deferred by 
one of the following:

- Holding kernel_lock (indicating that the code is not MT safe).
- Bracketing critical sections with kpreempt_disable/kpreempt_enable.
- Holding the interrupt priority level above IPL_NONE.

Statistics on kernel preemption are reported via event counters, and
where preemption is deferred for some reason, it's also reported via
lockstat. The LWP priority at which preemption is triggered is tuneable
via sysctl.
 2008-04-28 15:36:01 +00:00
ad 27168d9d58 - Rename crit_enter/crit_exit to kpreempt_disable/kpreempt_enable. 
DragonflyBSD uses the crit names for something quite different.
- Add a kpreempt_disabled function for diagnostic assertions.
- Add inline versions of kpreempt_enable/kpreempt_disable for primitives.
- Make some more changes for preemption safety to the x86 pmap.
 2008-04-27 11:37:48 +00:00
ad 15e29e981b Merge the socket locking patch: 
- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

With much feedback from matt@ and plunky@.

ad feb4783fdf Replace use of CACHE_LINE_SIZE in some obvious places. 2008-03-27 18:30:15 +00:00
ad ad4f28d1e9 Make them compile again. 2008-03-17 17:05:54 +00:00
yamt a67bae0b7b - simplify ASSERT_SLEEPABLE. 
- move it from proc.h to systm.h.
- add some more checks.
- make it a little more lkm friendly.
 2008-03-17 08:27:50 +00:00
martin d8788e7fd7 Use cpu index instead of the machine dependend, not very expressive 
cpuid when naming user-visible kernel entities.
 2008-03-10 22:20:14 +00:00
yamt 59a00111af pool_do_put: remove pa_starved_p check for now as it seems to cause 
more problems than it solves.  PR/37993 from Greg A. Woods.
 2008-03-02 12:19:58 +00:00
yamt 8ae4ab89dd use time_uptime instead of getmicrotime() for ph_time. 2008-02-14 11:45:24 +00:00
skrll fa0da8dc36 Revert previous as requested by yamt. 2008-02-05 10:11:19 +00:00
skrll 6b8ce99a9e Check alignment against pp->pr_align not pp->pr_alloc->pa_pagesz. 
DIAGNOSTIC kernels on hppa boot again.

OK'd by ad.
 2008-02-02 20:21:55 +00:00
yamt 4ad8bf4c8a pool_cache_get_paddr: don't bother to clear pcgo_va unless DIAGNOSTIC. 2008-01-28 10:26:12 +00:00
ad 0664a0459b Start detangling lock.h from intr.h. This is likely to cause short term 
breakage, but the mess of dependencies has been regularly breaking the
build recently anyhow.

ad 4a780c9ae2 Merge vmlocking2 to head. 2008-01-02 11:48:20 +00:00
ad ea3f10f7e0 Merge more changes from vmlocking2, mainly: 
- Locking improvements.
- Use pool_cache for more items.
 2007-12-26 16:01:34 +00:00
yamt 9108a50874 pool_in_cg: don't bother to check slots past pcg_avail. 2007-12-22 04:31:34 +00:00
yamt 0ce2491bde pool_whatis: print cached items as well. 2007-12-22 03:28:48 +00:00
ad 73157b0e11 - Support two different sizes of pool_cache group. The default has 14 or 15 
items, and the new large groups (for busy caches) have 62 or 63 items.
- Add PR_LARGECACHE flag as a hint that a pool_cache should use large groups.
  This should be eventually be tuned at runtime.
- Report group size for vmstat -C.
 2007-12-20 23:49:10 +00:00
yamt 0c38201391 add ddb "whatis" command. inspired from solaris ::whatis dcmd. 2007-12-13 02:45:09 +00:00
yamt b839442793 don't forget to initialize ph_off for PR_NOTOUCH. 2007-12-13 01:22:50 +00:00
ad 7b8aa25abc Change the ncpu test to work when a pool_cache or softint is initialized 
between mi_cpu_attach() and attachment of the boot CPU. Suggested by mrg@.
 2007-12-11 19:07:27 +00:00
ad 8cd835a351 pool_init, pool_cache_init: hack around IP input processing which can 
not yet safely block without severely confusing soo_write() and friends.
If the pool's IPL is IPL_SOFTNET, initialize the mutex at IPL_VM so that
it's a spinlock. To be dealt with correctly in the near future.
 2007-12-05 06:52:01 +00:00
ad 82a0bcef97 Work around issues with pool_cache on sparc. 2007-11-18 16:27:42 +00:00
yamt d2f81c7a05 fix freecheck. 2007-11-14 11:14:13 +00:00
yamt d4b8e5537d for PR_NOTOUCH pool_item_header, use a bitmap rather than a freelist. 
it saves some space and allows more items per a page.
