17 years agosched: reduce balance-tasks overhead

sched: reduce balance-tasks overhead

At the moment, balance_tasks() provides low level functionality for both
  move_tasks() and move_one_task() (indirectly) via the load_balance()
function (in the sched_class interface) which also provides dual
functionality.  This dual functionality complicates the interfaces and
internal mechanisms and makes the run time overhead of operations that
are called with two run queue locks held.

This patch addresses this issue and reduces the overhead of these
operations.

17 years agosched: fix sched_domain sysctl registration again
Milton Miller [Wed, 24 Oct 2007 16:23:48 +0000 (18:23 +0200)]
sched: fix sched_domain sysctl registration again

commit  029190c515f15f512ac85de8fc686d4dbd0ae731 (cpuset
sched_load_balance flag) was not tested SCHED_DEBUG enabled as
committed as it dereferences NULL when used and it reordered
the sysctl registration to cause it to never show any domains
or their tunables.

Fixes:

1) restore arch_init_sched_domains ordering
we can't walk the domains before we build them

presently we register cpus with empty directories (no domain
directories or files).

2) make unregister_sched_domain_sysctl do nothing when already unregistered
detach_destroy_domains is now called one set of cpus at a time
unregister_syctl dereferences NULL if called with a null.

While the the function would always dereference null if called
twice, in the previous code it was always called once and then
was followed a register.  So only the hidden bug of the
sysctl_root_table not being allocated followed by an attempt to
free it would have shown the error.

3) always call unregister and register in partition_sched_domains
The code is "smart" about unregistering only needed domains.
Since we aren't guaranteed any calls to unregister, always
unregister.   Without calling register on the way out we
will not have a table or any sysctl tree.

4) warn if register is called without unregistering
The previous table memory is lost, leaving pointers to the
later freed memory in sysctl and leaking the memory of the
tables.

Before this patch on a 2-core 4-thread box compiled for SMT and NUMA,
the domains appear empty (there are actually 3 levels per cpu).  And as
soon as two domains a null pointer is dereferenced (unreliable in this
case is stack garbage):

Convert mii (link state) monitor to acquire correct locks for
failover events.  In particular, failovers generally require RTNL at a low
level (when manipulating device MAC addresses, for example) and no other
locks.  The high level monitor is responsible for acquiring a known set

the low level failover processing can then release appropriate locks as
needed.  This patch provides the high level portion.

As it is undesirable to acquire RTNL for every monitor pass (which
may occur as often as every 10 ms), the miimon has been converted to
do conditional locking.  A first pass inspects all slaves to determine
if any action is required, and if so, a second pass (after acquring RTNL)
is done to perform any actions (doing a complete rescan, as the situation

x86: Force enable HPET for CK804 (nForce 4) chipsets

This patch adds a quirk from LinuxBIOS to force enable HPET on
the nVidia CK804 (nForce 4) chipset.

This quirk can very likely support more than just nForce 4
(LinuxBIOS use the same code for nForce 5), and possibly nForce 3,
but I don't have those chipsets, so cannot add and test them.

Tested on an Abit KN9 (CK804).
