* [PATCH] sched: balance on forkNick Piggin2005-06-25
| | | | | | | | | | | | | | | | | | Reimplement the balance on exec balancing to be sched-domains aware. Use this to also do balance on fork balancing. Make x86_64 do balance on fork over the NUMA domain. The problem that the non sched domains aware blancing became apparent on dual core, multi socket opterons. What we want is for the new tasks to be sent to a different socket, but more often than not, we would first load up our sibling core, or fill two cores of a single remote socket before selecting a new one. This gives large improvements to STREAM on such systems.

* [PATCH] sched: tweak affine wakeupsNick Piggin2005-06-25
| | | | | | | | | | | | | | | | | | Do less affine wakeups. We're trying to reduce dbt2-pgsql idle time regressions here... make sure we don't don't move tasks the wrong way in an imbalance condition. Also, remove the cache coldness requirement from the calculation - this seems to induce sharp cutoff points where behaviour will suddenly change on some workloads if the load creeps slightly over or under some point. It is good for periodic balancing because in that case have otherwise have no other context to determine what task to move. But also make a minor tweak to "wake balancing" - the imbalance tolerance is now set at half the domain's imbalance, so we get the opportunity to do wake balancing before the more random periodic rebalancing gets preformed.

* [PATCH] sched: balance timersNick Piggin2005-06-25
| | | | | | | | | | | | | Do CPU load averaging over a number of different intervals. Allow each interval to be chosen by sending a parameter to source_load and target_load. 0 is instantaneous, idx > 0 returns a decaying average with the most recent sample weighted at 2^(idx-1). To a maximum of 3 (could be easily increased). So generally a higher number will result in more conservative balancing.

* [PATCH] sched: fix SMT scheduling problemsNick Piggin2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | SMT balancing has a couple of problems. Firstly, active_load_balance is too complex - basically it should be a dumb helper for when the periodic balancer has determined there is an imbalance, but gets stuck because the task is running. So rip out all its "smarts", and just make it move one task to the target CPU. Second, the busy CPU's sched-domain tree was being used for active balancing. This means that it may not see that nr_balance_failed has reached a critical level. So use the target CPU's sched-domain tree for this. We can do this because we hold its runqueue lock. Lastly, reset nr_balance_failed to a point where we allow cache hot migration. This will help ensure active load balancing is successful. Thanks to Suresh Siddha for pointing out these issues.

* [PATCH] sched: reduce active load balancingNick Piggin2005-06-25
| | | | | | | | | | | Fix up active load balancing a bit so it doesn't get called when it shouldn't. Reset the nr_balance_failed counter at more points where we have found conditions to be balanced.

* [PATCH] sched: improve load balancing pinned tasksNick Piggin2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | John Hawkes explained the problem best: A large number of processes that are pinned to a single CPU results in every other CPU's load_balance() seeing this overloaded CPU as "busiest", yet move_tasks() never finds a task to pull-migrate. This condition occurs during module unload, but can also occur as a denial-of-service using sys_sched_setaffinity(). Several hundred CPUs performing this fruitless load_balance() will livelock on the busiest CPU's runqueue lock. A smaller number of CPUs will livelock if the pinned task count gets high. Expanding slightly on John's patch, this one attempts to work out whether the balancing failure has been due to too many tasks pinned on the runqueue. This allows it to be basically invisible to the regular blancing paths (ie. when there are no pinned tasks). We can use this extra knowledge to shut down the balancing faster, and ensure the migration threads don't start running which is another problem observed in the wild.

| | | | | | | | | | | | | | | | | Here is the fix for the problem described in http://bugzilla.kernel.org/show_bug.cgi?id=4721 Basically, problem is generic_file_buffered_write() is accessing beyond end of the iov[] vector after handling the last vector. If we happen to cross page boundary, we get a fault. I think this simple patch is good enough. If we really don't want to depend on the "count", then we need pass nr_segs to filemap_set_next_iovec() and decrement it and check it.

* [PATCH] RCU: clean up a few remaining synchronize_kernel() callsPaul E. McKenney2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.12-rc6-mm1 has a few remaining synchronize_kernel()s, some (but not all) in comments. This patch changes these synchronize_kernel() calls (and comments) to synchronize_rcu() or synchronize_sched() as follows: - arch/x86_64/kernel/mce.c mce_read(): change to synchronize_sched() to handle races with machine-check exceptions (synchronize_rcu() would not cut it given RCU implementations intended for hardcore realtime use. - drivers/input/serio/i8042.c i8042_stop(): change to synchronize_sched() to handle races with i8042_interrupt() interrupt handler. Again, synchronize_rcu() would not cut it given RCU implementations intended for hardcore realtime use. - include/*/kdebug.h comments: change to synchronize_sched() to handle races with NMIs. As before, synchronize_rcu() would not cut it... - include/linux/list.h comment: change to synchronize_rcu(), since this comment is for list_del_rcu(). - security/keys/key.c unregister_key_type(): change to synchronize_rcu(), since this is interacting with RCU read side. - security/keys/process_keys.c install_session_keyring(): change to synchronize_rcu(), since this is interacting with RCU read side.

* [PATCH] s390: debug feature changesMichael Holzheu2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the memory allocation method for the s390 debug feature. Trace buffers had been allocated using the get_free_pages() function before. Therefore it was not possible to get big memory areas in a running system due to memory fragmentation. Now the trace buffers are subdivided into several subbuffers with pagesize. Therefore it is now possible to allocate more memory for the trace buffers and more trace records can be written. In addition to that, dynamic specification of the size of the trace buffers is implemented. It is now possible to change the size of a trace buffer using a new debugfs file instance. When writing a number into this file, the trace buffer size is changed to 'number * pagesize'. In the past all the traces could be obtained from userspace by accessing files in the "proc" filesystem. Now with debugfs we have a new filesystem which should be used for debugging purposes. This patch moves the debug feature from procfs to debugfs. Since the interface of debug_register() changed, all device drivers, which use the debug feature had to be adjusted.
