394cb30a36 Rewrite node's r/w/q-lock semantics using only atomics instead of mutex
and atomics combination. Mutex is now used only for queue protection.
Also avoid unneded extra swi scheduling calls.

8aa9e82e67 Move INTR_FILTER from opt_global.h to its own header. 2008-04-05 20:13:15 +00:00
John Baldwin
1ee1b68792 Add a MI intr_event_handle() routine for the non-INTR_FILTER case. This
allows all the INTR_FILTER #ifdef's to be removed from the MD interrupt
code.
- Rename the intr_event 'eoi', 'disable', and 'enable' hooks to
  'post_filter', 'pre_ithread', and 'post_ithread' to be less x86-centric.
  Also, add a comment describe what the MI code expects them to do.
- On amd64, i386, and powerpc this is effectively a NOP.
- On arm, don't bother masking the interrupt unless the ithread is
  scheduled in the non-INTR_FILTER case to match what INTR_FILTER did.
  Also, don't bother unmasking the interrupt in the post_filter case if
  we never masked it.  The INTR_FILTER case had been doing this by having
  arm_unmask_irq for the post_filter (formerly 'eoi') hook.
- On ia64, stray interrupts are now masked for the non-INTR_FILTER case.
  They were already masked in the INTR_FILTER case.
- On sparc64, use the a NULL pre_ithread hook and use intr_enable_eoi() for
  both the 'post_filter' and 'post_ithread' hooks to match what the
  non-INTR_FILTER code did.
- On sun4v, retire the ithread wrapper hack by using an appropriate
  'post_ithread' hook instead (it's what 'post_ithread'/'enable' was
  designed to do even in 5.x).

9c9191983b During attach on some de(4) adapters the driver sends out a test packet as
part of detecting the media.  Explicitly ensure that we don't send it to
bpf(4) as bpf(4) isn't setup yet.  This worked by accident before the bpf
interface stuff was reworked to avoid other races (bpf_peers_present, etc.)
but now it needs an explicit check to avoid a panic.

7630c26507 Reintroduce UMA_SLAB_KMAP; however, change its spelling to
UMA_SLAB_KERNEL for consistency with its sibling UMA_SLAB_KMEM.
(UMA_SLAB_KMAP met its original demise in revision 1.30 of
vm/uma_core.c.)  UMA_SLAB_KERNEL is now required by the jumbo frame
allocators.  Without it, UMA cannot correctly return pages from the
jumbo frame zones to the VM system because it resets the pages' object
field to NULL instead of the kernel object.  In more detail, the jumbo
frame zones are created with the option UMA_ZONE_REFCNT.  This causes
UMA to overwrite the pages' object field with the address of the slab.
However, when UMA wants to release these pages, it doesn't know how to
restore the object field, so it sets it to NULL.  This change teaches
UMA how to reset the object field to the kernel object.

00ca09449d - Add sysctls at debug.rwlock to control the behavior of the speculative
spinning when readers hold a lock.  This spinning is speculative because,
   unlike the write case, we can not test whether the owners are running.
 - Add speculative read spinning for readers who are blocked by pending
   writers while a read lock is still held.  This allows the thread to
   spin until the write lock succeeds after which it may spin until the
   writer has released the lock.  This prevents excessive context switches
   when readers and writers both hold the lock for brief periods.

0502fe2e43 - Allow static_boost to specify no boost with '0', traditional kernel
fixed pri boost with '1' or any priority less than the current thread's
   priority with a value greater than two.  Default the boost to
   PRI_MIN_TIMESHARE to prevent regular user-space threads from starving
   threads in the kernel.  This prevents these user-threads from also
   being scheduled as if they are high fixed-priority kernel threads.
