2.5.64-mm2

[Andrew Morton]

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.64/2.5.64-mm2/

Just lots of little stuff here.  Mainly a resync with various people.

Note: there is a change to the console handling code in Linus's tree which
means that if you have both VT console and serial console enabled in kernel
config, the serial console now wins.  Nothing comes out on the screen during
bootup.  It used to be the case that the VT console was initialised first.

If this happens you will need to specify the console device on the boot
command line.

We appear to have at least three use-after-free bugs.  One is fixed here, and
there are extra debugging goodies which may help us find the others.  Please
enable memory debugging and keep an eye open.

[patch] updated scheduler-tunables for 2.5.64-mm2

[Robert Love]

Whoops.  Someone edited the scheduler-tunables.patch so it applied on
top of the interactivity changes, but then did not carry over those
changes to the tunable parameters in the patch ;)

So we end up with the usual values, and not the tuned parameters from
mainline.  Which is a shame, you know?

Attached patch is a complete replacement for the old patch.  It defaults
the tunable parameters to the new values in 2.5-bk.  I also added a
tuning knob for the NUMA node threshold stuff.

So we end up with:

        [22:42:31]rml@phantasy:~$ pef /proc/sys/sched
        child_penalty=50
        exit_weight=3
        interactive_delta=2
        max_sleep_avg=10000
        max_timeslice=200
        min_timeslice=10
        node_threshold=125
        parent_penalty=100
        prio_bonus_ratio=25
        starvation_limit=10000

Which looks good to me.

Andrew, please replace this for that stinky old one.  Thanks.

	Robert Love

+2.11 /proc/sys/sched - scheduler tunables
+-----------------------------------------
+
+Useful knobs for tuning the scheduler live in /proc/sys/sched.
+
+child_penalty
+-------------
+
+Percentage of the parent's sleep_avg that children inherit.  sleep_avg is
+a running average of the time a process spends sleeping.  Tasks with high
+sleep_avg values are considered interactive and given a higher dynamic
+priority and a larger timeslice.  You typically want this some value just
+under 100.
+
+exit_weight
+-----------
+
+When a CPU hog task exits, its parent's sleep_avg is reduced by a factor of
+exit_weight against the exiting task's sleep_avg.
+
+interactive_delta
+-----------------
+
+If a task is "interactive" it is reinserted into the active array after it
+has expired its timeslice, instead of being inserted into the expired array.
+How "interactive" a task must be in order to be deemed interactive is a
+function of its nice value.  This interactive limit is scaled linearly by nice
+value and is offset by the interactive_delta.
+
+max_sleep_avg
+-------------
+
+max_sleep_avg is the largest value (in ms) stored for a task's running sleep
+average.  The larger this value, the longer a task needs to sleep to be
+considered interactive (maximum interactive bonus is a function of
+max_sleep_avg).
+
+max_timeslice
+-------------
+
+Maximum timeslice, in milliseconds.  This is the value given to tasks of the
+highest dynamic priority.
+
+min_timeslice
+-------------
+
+Minimum timeslice, in milliseconds.  This is the value given to tasks of the
+lowest dynamic priority.  Every task gets at least this slice of the processor
+per array switch.
+
+parent_penalty
+--------------
+
+Percentage of the parent's sleep_avg that it retains across a fork().
+sleep_avg is a running average of the time a process spends sleeping.  Tasks
+with high sleep_avg values are considered interactive and given a higher
+dynamic priority and a larger timeslice.  Normally, this value is 100 and thus
+task's retain their sleep_avg on fork.  If you want to punish interactive
+tasks for forking, set this below 100.
+
+prio_bonus_ratio
+----------------
+
+Middle percentage of the priority range that tasks can receive as a dynamic
+priority.  The default value of 25% ensures that nice values at the
+extremes are still enforced.  For example, nice +19 interactive tasks will
+never be able to preempt a nice 0 CPU hog.  Setting this higher will increase
+the size of the priority range the tasks can receive as a bonus.  Setting
+this lower will decrease this range, making the interactivity bonus less
+apparent and user nice values more applicable.
+
+starvation_limit
+----------------
+
+Sufficiently interactive tasks are reinserted into the active array when they
+run out of timeslice.  Normally, tasks are inserted into the expired array.
+Reinserting interactive tasks into the active array allows them to remain
+runnable, which is important to interactive performance.  This could starve
+expired tasks, however, since the interactive task could prevent the array
+switch.  To prevent starving the tasks on the expired array for too long. the
+starvation_limit is the longest (in ms) we will let the expired array starve
+at the expense of reinserting interactive tasks back into active.  Higher
+values here give more preferance to running interactive tasks, at the expense
+of expired tasks.  Lower values provide more fair scheduling behavior, at the
+expense of interactivity.  The units are in milliseconds.

Re: [patch] updated scheduler-tunables for 2.5.64-mm2

I am in an accommodating mood... while the first patch was most likely
easiest for Andrew to use (swap out the old for the new), an incremental
diff is probably easier for the users to just apply on top of
2.5.64-mm2.

So here is an incremental diff, which has the following changes over
what is in 2.5-mm now:

	- update the tunable parameters to have the new defaults
	  Linus applied to 2.5-bk.  These defaults are similar to
	  the values in the sched-rml-updates.patch Andrew had
	  in here for awhile, and I like them.

	- add tuning for the node_threshold parameter for NUMA
	  folks

I encourage users to apply this, since we are getting close to sniffing
out the last of the interactivity woes and these updated parameters are
a large part of the solution.

Enjoy,

	Robert Love

Here's my .config. I am not SMP.

I suspected the distclean thing, but I made "Mr. Proper" too just in
case.

Check it out. I also just tryed redhat's gcc 2.96, same results.

Did you do a `make distclean' before building?  If not, can you?

And what combination of SMP + PREEMPT are you?  I assume you are
UP+PREEMPT, since that was what we changed.  It should not matter,
though... I think you just need to clean.

Let me know.

Oh.  Its those damn modules.  The bane of my existence.

Problem is, ksyms.c is exporting kernel_flag under PREEMPT.  Now we just
need it exported under SMP.

Andrew, would you mind appending this to the current patch? Sorry.

Everyone else, you need this if you are UP+PREEMPT+MODULES.

Now I oops on boot justt when it trys to mount root (reiserfs),

I'll try booting with vesa fbcon to see if I can't see more.

Eliminate initrd (eliminate using it, not support for it) and oops goes
away. Weird.

Re: [patch] updated scheduler-tunables for 2.5.64-mm2

Cool ... do you want to add the other two NUMA parameters as well to
your stack? (the idle and busy rebalance rates). Here's what I had

+
+2.11 /proc/sys/sched - scheduler tunables
+-----------------------------------------
+
+Useful knobs for tuning the scheduler live in /proc/sys/sched.
+
+child_penalty
+-------------
+
+Percentage of the parent's sleep_avg that children inherit.  sleep_avg is
+a running average of the time a process spends sleeping.  Tasks with high
+sleep_avg values are considered interactive and given a higher dynamic
+priority and a larger timeslice.  You typically want this some value just
+under 100.
+
+exit_weight
+-----------
+
+When a CPU hog task exits, its parent's sleep_avg is reduced by a factor of
+exit_weight against the exiting task's sleep_avg.
+
+interactive_delta
+-----------------
+
+If a task is "interactive" it is reinserted into the active array after it
+has expired its timeslice, instead of being inserted into the expired array.
+How "interactive" a task must be in order to be deemed interactive is a
+function of its nice value.  This interactive limit is scaled linearly by nice
+value and is offset by the interactive_delta.
+
+max_sleep_avg
+-------------
+
+max_sleep_avg is the largest value (in ms) stored for a task's running sleep
+average.  The larger this value, the longer a task needs to sleep to be
+considered interactive (maximum interactive bonus is a function of
+max_sleep_avg).
+
+max_timeslice
+-------------
+
+Maximum timeslice, in milliseconds.  This is the value given to tasks of the
+highest dynamic priority.
+
+min_timeslice
+-------------
+
+Minimum timeslice, in milliseconds.  This is the value given to tasks of the
+lowest dynamic priority.  Every task gets at least this slice of the processor
+per array switch.
+
+parent_penalty
+--------------
+
+Percentage of the parent's sleep_avg that it retains across a fork().
+sleep_avg is a running average of the time a process spends sleeping.  Tasks
+with high sleep_avg values are considered interactive and given a higher
+dynamic priority and a larger timeslice.  Normally, this value is 100 and thus
+task's retain their sleep_avg on fork.  If you want to punish interactive
+tasks for forking, set this below 100.
+
+prio_bonus_ratio
+----------------
+
+Middle percentage of the priority range that tasks can receive as a dynamic
+priority.  The default value of 25% ensures that nice values at the
+extremes are still enforced.  For example, nice +19 interactive tasks will
+never be able to preempt a nice 0 CPU hog.  Setting this higher will increase
+the size of the priority range the tasks can receive as a bonus.  Setting
+this lower will decrease this range, making the interactivity bonus less
+apparent and user nice values more applicable.
+
+starvation_limit
+----------------
+
+Sufficiently interactive tasks are reinserted into the active array when they
+run out of timeslice.  Normally, tasks are inserted into the expired array.
+Reinserting interactive tasks into the active array allows them to remain
+runnable, which is important to interactive performance.  This could starve
+expired tasks, however, since the interactive task could prevent the array
+switch.  To prevent starving the tasks on the expired array for too long. the
+starvation_limit is the longest (in ms) we will let the expired array starve
+at the expense of reinserting interactive tasks back into active.  Higher
+values here give more preferance to running interactive tasks, at the expense
+of expired tasks.  Lower values provide more fair scheduling behavior, at the
+expense of interactivity.  The units are in milliseconds.
+
+idle_node_rebalance_ratio
+-------------------------
+
+On NUMA machines, we normally rebalance within nodes, but we also rebalance
+globally every N idle rebalance ticks, where N = idle_node_rebalance_ratio.
+
+busy_node_rebalance_ratio
+-------------------------
+
+On NUMA machines, we normally rebalance within nodes, but we also rebalance

Sure.

But at least in 2.5.64 and 2.5.64-mm3, I do not see those parameters. 
There is no {IDLE|BUSY}_NODE_REBALANCE_TICK define.
