Andrew, this requires a little more fixing than your simple patch.
Several drivers omit 'regs' from the receive handler when sysrq is
not enabled.  Hence, this simple fix on its own will cause compile
failures.

Me no understand.  It replaces a three-arg macro with a three-arg static
inline?

Some serial drivers drop 'regs' from the parent function when sysrq is
disabled.  'regs' is only passed for sysrq support.

(Yes, it's disgusting, but I thought at the time I had the choice of
being lynched by the "as efficient as possible" mob, or...)

Me still no understand.

+static inline int uart_handle_sysrq_char(struct uart_port *port,
+               unsigned int ch, struct pt_regs *regs)
+{
+       return 0;
+}
	
That function doesn't touch *regs, and all callers pass in either
a pt_regs* or NULL??

Also GITtable, as soon as the mirrors' work is done:

... since people asked:
- trees from GIT are properly parent-linked.
- yes, I can import other people's patch series.
- the whole import runs in a couple of minutes.
  In fact, I keep suspecting that it must be skipping some important
  step or other. ;-)  Kudos to Linus, and of course everybody else who's
  involved with git, for yet another tool done *right*.

Yes, quite.  How about the following to correct the intention.



Add correct Kconfig option for ISP24xx support.

Andrew, do we really need to add every piece of crap lying on the street
to -mm?  It's far away from mainline enough already without adding obviously
unmergeable stuff like this.

My gut reaction to ckrm is the same as yours.  But there's been a lot of
work put into this and if we're to flatly reject the feature then the
developers are owed a much better reason than "eww yuk".

Otherwise, if there are certain specific problems in the code then it's
best that they be pointed out now rather than later on.

What, in your opinion, makes it "obviously unmregeable"?

Well arch/mips/Kconfig is defining CONFIG_FB as bool and
drivers/video/Kconfig was changed a while ago to define it as tristate.  I
assume this failure also happens in linus's current tree.  

It seems odd that mips is privately duplicating the generic code's
definition.  Maybe that needs to be taken out of there.

I'll cc the fbdev guys - could someone please come up with fix?  It's a
showstopper for the MIPS architecture.

Thanks.
Can you please resend with proper changelog and signed-off-by.
Diff should be done on top of latest -linus preferable.
Also this patch seems relative small compared to the others floating
around to cure signed warnings in scripts/
Does this really fix all of them or only a subset of the warnings?

I do not have gcc4 present but maybe thats easy - running gentoo?

Can we have a local variable so we do not have all the casts in the if
condition?

there should be also "select FW_LOADER", as it uses request_firmware &

There seems to be a regression wrt 2.6.13-rc3 which causes my box (Asus L5D,
Athlon 64 + nForce3) to hang solid during resume from disk on battery power.

First, 2.6.13-rc3-mm1 is affected by the problems described at:
http://bugzilla.kernel.org/show_bug.cgi?id=4416
http://bugzilla.kernel.org/show_bug.cgi?id=4665
These problems go away after applying the two attached patches.  Then, the
box resumes on AC power but hangs solid during resume on battery power.
The problem is 100% reproducible and I think it's related to ACPI.

Greets,
Rafael

 <1>Fixing recursive fault but reboot is needed!


It just happened once. I noticed it because I wasn't able to suspend to disk, gnome-setting was stuck in D state.

I don't know if this is specific to 2.6.13-rc3-mm1.

.config is attached below.

Feel free to ask for more information.

    I seem to recall that swsusp2 can do this.

    I don't hold out much hope that suspend will ever work on my
laptop, with its i815 video chipset, at least not from X (and then
there's no point).  The i81x and the linux video architecture just
don't get along, even if I do away with i810fb and DRM support.

    But I can't help but notice that every linux-suspend HOWTO tells
you to patch in swsusp2 as a first step -- the consensus seems to be
that it you want clean and conservative code, use swsusp1; if you want
suspending to *work*, use swsusp2.  How many people are actually able
to make use of swsusp1?  Is anyone testing it besides Mr. Machek?

    This is a case in point; every time I partition a system for
Linux, I have to consider whether or not I'm ever going to want swsusp
to work on that box.   The performance penalty for swap files went
away in 2.6, so this is sort of a regression.

    I know I'm not going to be writing any of those patches, but I'd
sure be nice if Linux got around to having usable suspend support
without being beholden to the whatever patches Mr. Cunningham gets
around to putting out.

It looks good (except that you used spaces instead of a tab in the 
"select" line, but that's only a minor nitpick).

Below is another fix for a different issue that was already present.

cu
Adrian


<--  snip  -->


SCSI_QLA2XXX is automatically enabled for (SCSI && PCI).
It therefore mustn't select SCSI_FC_ATTRS, since it otherwise 
unconditionally enables SCSI_FC_ATTRS for all users with
(SCSI && PCI) enabled, even when they don't need any support for
QLogic hardware.

This patch also does a cosmetic change for making the "default" look 
more like in other kernel code.

This has bugged me for a while.  Why does this one SCSI driver default

It's not a driver, it's a subdirectory.

Re: 2.6.13-rc3-mm1 (ckrm)

[Paul Jackson]

Andrew, replying to Christoph, about CKRM:
> What, in your opinion, makes it "obviously unmergeable"?

Thanks to some earlier discussions on the relation of CKRM with
cpusets, I've spent some time looking at CKRM.  I'm not Christoph,
but perhaps my notes will be of some use in this matter.

CKRM is big, it's difficult for us mere mortals to understand, and it
has attracted only limited review - inadequate review in proportion
to its size and impact.  I tried, and failed, sometime last year to
explain some of what I found difficult to grasp of CKRM to the folks
doing it.  See further an email thread entitled:

    Classes: 1) what are they, 2) what is their name?
    http://sourceforge.net/mailarchive/forum.php?thread_id=5328162&forum_id=35191

on the ckrm-tech@lists.sourceforge.net email list between Aug 14 and
Aug 27, 2004

As to its size, CKRM is in a 2.6.5 variant of SuSE that I happen to be
building just now for other reasons.  The source files that have 'ckrm'
in the pathname, _not_ counting Doc files, total 13044 lines of text.
The CONFIG_CKRM* config options add 144 Kbytes to the kernel text.

The CKRM patches in 2.6.13-rc3-mm1 are similar in size.  These patch
files total 14367 lines of text.

It is somewhat intrusive in the areas it controls, such as some large
ifdef's in kernel/sched.c.

The sched hooks may well impact the cost of maintaining the sched code,
which is always a hotbed of Linux kernel development.  However others
who work in that area will have to speak to that concern.

I tried just now to read through the ckrm hooks in fork, to see
what sort of impact they might have on scalability on large systems.
But I gave up after a couple layers of indirection.  I saw several
atomic counters and a couple of spinlocks that I suspect (not at all
sure) lay on the fork main code path.  I'd be surprised if this didn't
impact scalability.  Earlier, according to my notes, I saw mention of
lmbench results in the OLS 2004 slides, indicating a several percent
cost of available cpu cycles.

A feature of this size and impact needs to attract a fair bit of
discussion, because it is essential to a variety of people, or because
it is intriguing in some other way.

I suspect that the main problem is that this patch is not a mainstream
kernel feature that will gain multiple uses, but rather provides
support for a specific vendor middleware product used by that
vendor and a few closely allied vendors.  If it were smaller or
less intrusive, such as a driver, this would not be a big problem.
That's not the case.

The threshold of what is sufficient review needs to be set rather high
for such a patch, quite a bit higher than I believe it has obtained
so far.  It will not be easy for them to obtain that level of review,
until they get better at arousing the substained interest of other
kernel developers.

There may well be multiple end users and applications depending on
CKRM, but I have not been able to identify how many separate vendors
provide middleware that depends on CKRM.  I am guessing that only one
vendor has a serious middleware software product that provides full
CKRM support.  Acceptance of CKRM would be easier if multiple competing
middleware vendors were using it.  It is also a concern that CKRM
is not really usable for its primary intended purpose except if it
is accompanied by this corresponding middleware, which I presume is
proprietary code.  I'd like to see a persuasive case that CKRM is
useful and used on production systems not running substantial sole
sourced proprietary middleware.

The development and maintenance costs so far of CKRM appear (to
this outsider) to have been substantial, which suggests that the
maintenance costs of CKRM once in the kernel would be non-trivial.
Given the size of the project, its impact on kernel code, and the
rather limited degree to which developers outside of the CKRM project
have participated in CKRM's development or review, this could either
leave the Linux kernel overly dependent on one vendor for maintaining
CKRM, or place an undo maintenance burden on other kernel developers.

CKRM is in part a generalization and descendent of what I call fair
share schedulers.  For example, the fork hooks for CKRM include a
forkrates controller, to slow down the rate of forking of tasks using
too much resources.

No doubt the CKRM experts are already familiar with these, but for
the possible benefit of other readers:

  Communications of the ACM, January 1988, Volume 31, Number 1, pp 44-55.

The documentation that I've noticed (likely I've missed something)
doesn't do an adequate job of making the case - providing the
motivation and context essential to understanding this patch set.

Because CKRM provides an infrastructure for multiple controllers
(limiting forks, memory allocation and network rates) and multiple
classifiers and policies, its critical interfaces have rather
generic and abstract names.  This makes it difficult for others to
approach CKRM, reducing the rate of peer review by other Linux kernel
developers, which is perhaps the key impediment to acceptance of CKRM.
If anything, CKRM tends to be a little too abstract.

Inclusion of diffstat output would help convey to others the scope
of the patchset.

My notes from many months ago indicate something about a 128 CPU
limit in CKRM.  I don't know why, nor if it still applies.  It is
certainly a smaller limit than the systems I care about.

A major restructuring of this patch set could be considered,  This
might involve making the metric tools (that monitor memory, fork
and network usage rates per task) separate patches useful for other
purposes.  It might also make the rate limiters in fork, alloc and
network i/o separately useful patches.  I mean here genuinely useful
and understandable in their own right, independent of some abstract
CKRM framework.

Though hints have been dropped, I have not seen any public effort to
integrate CKRM with either cpusets or scheduler domains or process
accounting.  By this I don't mean recoding cpusets using the CKRM
infrastructure; that proposal received _extensive_ consideration
earlier, and I am as certain as ever that it made no sense.  Rather I
could imagine the CKRM folks extending cpusets to manage resources
on a per-cpuset basis, not just on a per-task or task class basis.
Similarly, it might make sense to use CKRM to manage resources on
a per-sched domain basis, and to integrate the resource tracking
of CKRM with the resource tracking needs of system accounting.

yes, that's the crux.  CKRM is all about resolving conflicting resource 
demands in a multi-user, multi-server, multi-purpose machine.  this is a 
huge undertaking, and I'd argue that it's completely inappropriate for 
*most* servers.  that is, computers are generally so damn cheap that 
the clear trend is towards dedicating a machine to a specific purpose, 
rather than running eg, shell/MUA/MTA/FS/DB/etc all on a single machine.  

this is *directly* in conflict with certain prominent products, such as 
the Altix and various less-prominent Linux-based mainframes.  they're all
about partitioning/virtualization - the big-iron aesthetic of splitting up 
a single machine.  note that it's not just about "big", since cluster-based 
approaches can clearly scale far past big-iron, and are in effect statically
partitioned.  yes, buying a hideously expensive single box, and then chopping 
it into little pieces is more than a little bizarre, and is mainly based
on a couple assumptions:

	- that clusters are hard.  really, they aren't.  they are not 
	necessarily higher-maintenance, can be far more robust, usually
	do cost less.  just about the only bad thing about clusters is 
	that they tend to be somewhat larger in size.

	- that partitioning actually makes sense.  the appeal is that if 
	you have a partition to yourself, you can only hurt yourself.
	but it also follows that burstiness in resource demand cannot be 
	overlapped without either constantly tuning the partitions or 
	infringing on the guarantee.

CKRM is one of those things that could be done to Linux, and will benefit a
few, but which will almost certainly hurt *most* of the community.

let me say that the CKRM design is actually quite good.  the issue is whether 
the extensive hooks it requires can be done (at all) in a way which does 
not disporportionately hurt maintainability or efficiency.

CKRM requires hooks into every resource-allocation decision fastpath:
	- if CKRM is not CONFIG, the only overhead is software maintenance.
	- if CKRM is CONFIG but not loaded, the overhead is a pointer check.
	- if CKRM is CONFIG and loaded, the overhead is a pointer check
	and a nontrivial callback.

but really, this is only for CKRM-enforced limits.  CKRM really wants to
change behavior in a more "weighted" way, not just causing an
allocation/fork/packet to fail.  a really meaningful CKRM needs to 
be tightly integrated into each resource manager - effecting each scheduler
(process, memory, IO, net).  I don't really see how full-on CKRM can be 
compiled out, unless these schedulers are made fully pluggable.

finally, I observe that pluggable, class-based resource _limits_ could 
probably be done without callbacks and potentially with low overhead.
but mere limits doesn't meet CKRM's goal of flexible, wide-spread resource 
partitioning within a large, shared machine.

I was afraid you would say so. ;-)

The -rc3-git-[2-4] kernels are unaffected by the problem described, so it seems
to be specific to -rc3-mm1.

Apparently, mount does not work with partitions located on a 3ware RAID
(8006-2PL controller) in a dual-Opteron box (64-bit kernel).

If the kernel is configured with preemption and NUMA, it cannot mount any
"real" filesystems and the output of "mount" is the following:

rootfs on / type ext3 (rw)
/dev/root on / type ext3 (rw)
proc on /proc type proc (rw,nodiratime)
sysfs on /sys type sysfs (rw)
tmpfs on /dev/shm type tmpfs (rw)

(hand-copied from the screen).  I have tried some other combinations (ie.
preemption w/o NUMA, NUMA w/o preemption etc.) and it seems that it works
better with CONFIG_PREEMPT_NONE set, although even it this case some
filesystems are mounted read-only.

The mainline kernels (ie. -rc3 and -rc3-git[1-4]) have no such problems.

Rafael

Hi,

Controlling resource assignment, I think that concept is good.
But the design is another matter that it seems somewhat overkilled
with the current CKRM.

I believe this feature would also make desktop users happier -- controlling
X-server, mpeg player, video capturing and all that -- if the code
becomes much simpler and easier to use.

Well, current -linus already has a patch from me to change the 
compression scheme that also fixes most of the signedness problems. The 
ones below escaped me because my gcc3.3.2 didn't complain about them 
even with all the -W[xxx] switches I could find.

This takes a big hunk out of previous patches I've seen, so that might 
explain the difference.

You are right, patch below.

qla_init.c now uses code that requires FW_LOADER.

Additionally, this patch removes spaces instead of tabs at the 
SCSI_FC_ATTRS selects.

I send a patch for this yesterday that lets SCSI_QLA2XXX select
FW_LOADER. I believe that's a bit better since the other options
depend on SCSI_QLA2XXX anyway, there's no point in having them all set
FW_LOADER. My patch also fixes another little issue; that you cannot
disable SCSI_QLA2XXX if you don't need it.

See the patch here: http://lkml.org/lkml/2005/7/19/147
The mail contains 3 patches, but the third one is the best fix IMHO.

That's not an issue, this seems to be intentional.

Whether SCSI_QLA2XXX should be user-visible (as your patches make it) or 
stay as it is (with the fixes from my patches) doesn't matter much - 
both are valid setups.

Useful info, thanks.

Faulty kernel programming ;)

I assume that the failure to open /dev/dri/card0 only happens in rc3-mm1?

Could you compare the dmesg output for 2.6.13-rc3 versus 2.6.13-rc3-mm1? 
And double-check the .config settings: occasionally config options will be
renamed and `make oldconfig' causes things to get acidentally disabled.

	The OLS2004 slides are roughly 1 year old. Have you looked at more
recent benchmarks posted on CKRM-Tech around April 15th 2005? They
should be available in the CKRM-Tech archives on SourceForge at
http://sourceforge.net/mailarchive/forum.php?thread_id=7025751&forum_id=35191

(OLS 2004 Slide 24 of
http://ckrm.sourceforge.net/downloads/ckrm-ols04-slides.pdf )

	The OLS slide indicates that the overhead is generally less than
0.5usec compared to a total context switch time of anywhere from 2 to
5.5usec. There appears to be little difference in scalability since the
overhead appears to oscillate around a constant.

	The Rule-Based Classification Engine (RBCE) makes CKRM useful without
middleware. It uses a table of rules to classify tasks. For example
rules that would classify shells:

echo 'path=/bin/bash,class=/rcfs/taskclass/shells' > /rcfs/ce/rules/classify_bash_shells
echo 'path=/bin/tcsh,class=/rcfs/taskclass/shells' > /rcfs/ce/rules/classify_tcsh_shells
..

And class shares would control the fork rate of those shells:

echo 'res=numtasks,forkrate=10000,forkrate_interval=1' > '/rcfs/taskclass/config'
echo 'res=numtasks,guarantee=1000,limit=5000' > '/rcfs/taskclass/shells'

No middleware necessary.

	The choice of algorithm is entirely up to the scheduler, memory
allocator, etc. CKRM currently provides an interface for reading share
values and does not impose any meaning on those shares -- that is the
role of the scheduler.

	Generic and abstract names are appropriate for infrastructure that is
not tied to hardware. If you could be more specific I'd be able to
respond in less general and abstract terms.

I haven't seen this limitation in the CKRM patches that went into -mm
and I'd like to look into this. Where did you see this limit?

The difference in the X logs is that the working one does not have the:

(II) RADEON(0): [drm] added 8192 byte SAREA at 0xffffc20000411000
(II) RADEON(0): [drm] drmMap failed

Hmm no idea what could have broken it, I'm at OLS and don't have any

Perhaps someone who knows CKRM better than I can explain why the CKRM
version in some SuSE releases based on 2.6.5 kernels has substantial
code and some large ifdef's in sched.c, but the CKRM in *-mm doesn't.
Or perhaps I'm confused.  There's a good chance that this represents
ongoing improvements that CKRM is making to reduce their footprint
in core kernel code.  Or perhaps there is a more sophisticated cpu
controller in the SuSE kernel.

I had not seen these before.  Thanks for the pointer.

> without middleware.

I'd be encouraged more if this went one step further, past pointing
out that the API can be manipulated from the shell without requiring C
code, to providing examples of who intends to _directly_ use this
interface. The issue is perhaps less whether it's API is naturally C or
shell code, or more of how many actual, independent, uses of this API
are known to the community.  A non-trivial API and mechanism that
is de facto captive to a single middleware implementation (which
may or may not apply here - I don't know) creates an additional review
burden, because some of the natural forces that guide us to healthy
long lasting interfaces are missing.  If that concern applies here,
it's certainly not insurmountable - but it should in my view raise the
review barrier to acceptance.  If other middleware or direct users
are not essentially performing some of the review for us, we have to do
it here with greater thoroughness.

Good come back <grin>.

I made an effort along these lines last year, in the thread
I referenced a few days ago:

    Classes: 1) what are they, 2) what is their name?

I doubt that it I have much more to contribute along
these lines now.

No offense, but I really don't see why this matters at all ... the stuff
in -mm is what's under consideration for merging - what's in SuSE is
wholly irrelevant ? One obvious thing is that that codebase will be
much older ... would be useful if people can direct critiques at the
current codebase ;-)

As there is NO CKRM cpu controller in 2.6.13-rc3-mm1 (that I can see) 
the one in 2.6.5 is certainly more sophisticated :-).  So the reason 
that the considerable mangling of sched.c evident in SuSE's 2.6.5 kernel 
source is not present is that the cpu controller is not included in 
these patches.

I imagine that the cpu controller is missing from this version of CKRM 
because the bugs introduced to the cpu controller during upgrading from 
2.6.5 to 2.6.10 version have not yet been resolved.

 Yeah - I don't really consider the current CPU controller code something
 ready for consideration yet for mainline merging.  That doesn't mean
 we don't want a CPU controller for CKRM - just that what we have
 doesn't integrate cleanly/nicely with mainline.

 I don't know what bugs you are referring to here.  I don't think we
 have any open defects with SuSE on the CPU scheduler in their releases.
 And that is not at all related to the reason for not having a CPU
 controller in the current patch set.

Yes - what's in SuSE doesn't matter, at least not directly.

No - we are not just considering the CKRM that is in *-mm now, but also
what can be expected to be proposed as part of CKRM in the future.

If the CPU controller is not in *-mm now, but if one might reasonably
expect it to be proposed as part of CKRM in the future, then we need to
understand that.  This is perhaps especially important in this case,
where there is some reason to suspect that this additional piece is
both non-trivial and essential to CKRM's purpose.

The bugs were in the patches for the 2.6.10 kernel not SuSE's 2.6.5 
kernel.  I reported some of them to the ckrm-tech mailing list at the 
time.  There were changes to the vanilla scheduler between 2.6.5 and 
2.6.10 that were not handled properly when the CKRM scheduler was 
upgraded to the 2.6.10 kernel.

Ah - okay - that makes sense.  Those patches haven't gone through my
review yet and I'm not directly tracking their status until I figure
out what the right direction is with respect to a fair share style
scheduler of some sort.  I'm not convinced that the current one is
something that is ready for mainline or is necessarily the right answer
currently.  But we do need to figure out something that will provide
some level of CPU allocation minima & maxima for a class, where that
solution will work well on a laptop or a huge server.

Ideas in that space are welcome - I know of several proposed ideas
in progress - the scheduler in SuSE and the forward port to 2.6.10
that you referred to; an idea for building a very simple interface
on top of sched_domains for SMP systems (no fairness within a
single CPU) and a proposal for timeslice manipulation that might
provide some fairness that the Fujitsu folks are thinking about.
There are probably others and honestly, I don't have any clue yet as
to what the right long term/mainline direction should be here as yet.

The argument about scale-up vs. scale-out is nowhere close to being 
resolved. To argue that any support for performance partitioning (which 
CKRM does) is in support of a lost cause is premature to say the least.

"constantly tuning the partitions" is effectively whats done by workload 
managers. But our earlier presentations and papers have made the case 
that this is not the only utility for performance isolation - simple 
needs like isolating one user from another on a general purpose server 
is also a need that cannot be met by any existing or proposed Linux 
kernel mechanisms today.

If partitioning made so little sense and the case for clusters was that 
obvious, one would be hard put to explain why server consolidation is 
being actively pursued by so many firms, Solaris is bothering with 
coming up with Containers and Xen/VMWare getting all this attention.
I don't think the concept of partitioning can be dismissed so easily.

Of course, it must be noted that CKRM only provides performance 
isolation not fault isolation. But there is a need for that. Whether 
Linux chooses to let this need influence its design is another matter 
(which I hope we'll also discuss besides the implementation issues).

This is a valid point for the CPU, memory and network controllers (I/O 
can be made pluggable quite easily). For the CPU controller in SuSE, the 
CKRM CPU controller can be turned on and off dynamically at runtime. 
Exploring a similar option for  memory and network (incurring only a 
pointer check) could be explored. Keeping the overhead close to zero for 
kernel users not interested in CKRM is certainly one of our objectives.

True but only limits are not as useful for general workload management.

The CKRM design explicitly considered this problem of some controllers 
being more unacceptable than the rest and part of the indirections 
introduced in CKRM are to allow the kernel community the flexibility of 
cherry-picking acceptable controllers. So if the current CPU controller 
   implementation is considered too intrusive/unacceptable, it can be 
reworked or (and we certainly hope not) even rejected in perpetuity. 
Same for the other controllers as and when they're introduced and 
proposed for inclusion.

This is a big NAK - if computers are so damn cheap, why is virtualization
and consolidation such a big deal?  Well, the answer is actually that
floor space, heat, and power are also continuing to be very important
in the overall equation.  And, buying machines which are dedicated but
often 80-99% idle occasionally bothers people who are concerned about
wasting planetary resources for no good reason.  Yeah, we can stamp out
thousands of metal boxes, but if just a couple can do the same work,
well, let's consolidate.  Less wasted metal, less wasted heat, less
wasted power, less air conditioning, wow, we are now part of the
eco-computing movement!  ;-)

Well, yeah IBM has been doing this virtualization & partitioning stuff
for ages at lots of different levels for lots of reasons.  If we are
in such direct conflict with Altix, aren't we also in conflict with our
own lines of business which do the same thing?  But, well, we aren't
in conflict - this is a complementary part of our overall capabilities.

This is orthogonal to clusters.  Or, well, we are even using CKRM today
is some grid/cluster style applications.  But that has no bearing on
whether or not clusters is useful.

Well, if you don't think it makes sense, don't buy one.  And stay away
from Xen, VMware, VirtualIron, PowerPC/pSeries hardware, Mainframes,
Altix, IA64 platforms, Intel VT, AMD Pacifica, and, well, anyone else
that is working to support virtualization, which is one key level of
partitioning.

I'm sorry but I'm not buying your argument here at all - it just has
no relationship to what's going on at the user side as near as I can
tell.

Can you be more clear on how this will hurt *most* of the community?
CKRM when not in use is not in any way intrusive.  Can you take a look
at the patch again and point out the "extensive" hooks for me?  I've
looked at "all" of them and I have trouble calling a couple of callbacks
"extensive hooks".

You left out a case here:  CKRM is CONFIG and loaded and classes are
defined.

In all of the cases that you mentioned, if there are no classes
defined, the overhead is still unmeasurable for any real workload.
Refer to the archives referenced earlier where Nish did some performance
measurements/comparisons.  If you think there are real workloads where
this is non-trivial, can you run, measure, and point out the cost?  Also,
do this with and without classes defined.  I think that without classes
defined, you'll be hard pressed to find a real workload that shows any
statistically significant performance impact.

Well, loadable modules make sense for some items - what cost there is
(which is still often small) is born only by the users that use that
specific portion of CKRM.  But not everything is likely to be a loadable
module, e.g. the memory controller and the CPU scheduler components
are a bit tougher.  And yes, we are concerned about performance on big
and small machines, so that is always a concern with CKRM as well as
with any patches in any subsystem.

CKRM's goal is to do simple workload management both on laptops and
on servers.  I'm not opposed to doing a few things overly simply as long
as we get some basic capability.  And we can refine with experience.  I'm
definitly not looking to make CKRM any more complex than it has to
be, and yet I also want it to be useful on a laptop, small single CPU
machine, as well as larger servers.

yes, you did miss my point.  I'm actually arguing that it's bad design
to attempt to arbitrate within a single shared user-space.  you make 
the fast path slower and less maintainable.  if you are really concerned
about isolating many competing servers on a single piece of hardware, then
run separate virtualized environments, each with its own user-space.

I'm willing to agree to disagree.  I'm in favor of full virtualization
as well, as it is appropriate to certain styles of workloads.  I also
have enough end users who also want to share user level, share tasks,
yet also have some level of balancing between the resource consumption
of the various environments.  I don't think you are one of those end
users, though.  I don't think I'm required to make everyone happy all
the time.  ;)

And the virtualisation layer has to do the same job with less
information. That to me implies that the virtualisation case is likely
to be materially less efficient, its just the inefficiency you are
worried about is hidden in a different pieces of code.

Secondly a lot of this doesnt matter if CKRM=n compiles to no code

I'm actually trying to keep the impact of CKRM=y to near-zero, ergo
only an impact if you create classes.  And even then, the goal is to
keep that impact pretty small as well.

And yes, a hypervisor does have a lot more overhead in many forms.
Something like an overall 2-3% everywhere, where the CKRM impact is
likely to be so small as to be hard to measure in the individual
subsystems, and overall performance impact should be even smaller.
Plus you won't have to manage each operating system instance which
can grow into a pain under virtualization.  But I still maintain that
both have their place.

I imagine you, like me, are currently sitting in the Xen talk,
and I don't believe they are or will do anything so dumb as to throw away
or lose information.  yes, in principle, the logic will need to be 
somewhere, and I'm suggesting that the virtualization logic should
be in VMM-only code so it has literally zero effect on host-native 
processes.  *or* the host-native fast-path.

but to really do CKRM, you are going to want quite extensive interaction with
the scheduler, VM page replacement policies, etc.  all incredibly
performance-sensitive areas.

actually, let me also say that CKRM is on a continuum that includes 
current (global) /proc tuning for various subsystems, ulimits, and 
at the other end, Xen/VMM's.  it's conceivable that CKRM could wind up
being useful and fast enough to subsume the current global and per-proc
tunables.  after all, there are MANY places where the kernel tries to 
maintain some sort of context to allow it to tune/throttle/readahead
based on some process-linked context.  "embracing and extending"
those could make CKRM attractive to people outside the mainframe market.

I don't see why you are concerned. If the CKRM=n path is zero impact
then its irrelevant to you. Its more expensive to do a lot of resource
management at the VMM level because the virtualisation engine doesn't
know anything but its getting indications someone wants to be
bigger/smaller.

Bingo - and areas the virtualiser can't see into, at least not unless it
uses the same hooks CKRM uses

It is certainly reasonable that you would hope such.

But this hypothetical possibility concerns me a little.  Where would
that leave CKRM, if it was in the mainline kernel, but there was no CPU
controller in the mainline kernel?  Wouldn't that be a rather serious
problem for many users of CKRM if they wanted to work on mainline
kernels?

	Seems like an excellent suggestion to me! Yeah, it may be possible to
maintain the context the kernel keeps on a per-class basis instead of
globally or per-process. The real question is what constitutes a useful
"extension" :).

	I was thinking that per-class nice values might be a good place to
start as well. One advantage of per-class as opposed to per-process nice
is the class is less transient than the process since its lifetime is
determined solely by the system administrator.

	CKRM calls this kind of module a "resource controller". There's a small
HOWTO on writing resource controllers here:
http://ckrm.sourceforge.net/ckrm-controller-howto.txt
If anyone wants to investigate writing such a controller please feel
free to ask questions or send HOWTO feedback on the CKRM-Tech mailing

right, but are the CKRM people ready to take this on?  for instance,
I just grepped 'throttle' in kernel/mm and found a per-task RM in 
page-writeback.c.  it even has a vaguely class-oriented logic, since
it exempts RT tasks.  if CKRM can become a way to make this stuff 
cleaner and more effective (again, for normal tasks), then great.
but bolting on a big new different, intrusive mechanism that slows
down all normal jobs by 3% just so someone can run 10K mostly-idle
guests on a giant Power box, well, that's gross.

if CKRM is just extensions, I think it should be an external patch.
if it provides a path towards unifying the many disparate RM mechanisms
already in the kernel, great!

but the Linux RM needs to subsume traditional Unix process groups,
and inherited nice/schd class, and even CAP_ stuff.  I think CKRM
could start to do this, since classes are very general.
but merely adding a new, incompatible feature is just Not A Good Idea.

OK, so if it provides a path towards unifying these, what should happen
to the old interfaces when they conflict with those offered by CKRM?

For instance, I'm considering how a per-class (re)nice setting would
work. What should happen when the user (re)nices a process to a
different value than the nice of the process' class? Should CKRM:

a) disable the old interface by
	i) removing it
	ii) return an error when CKRM is active
	iii) return an error when CKRM has specified a nice value for the
process via membership in a class
	iv) return an error when the (re)nice value is inconsistent with the
nice value assigned to the class

b) trust the user, ignore the class nice value, and allow the new nice
value

	I'd be tempted to do a.iv but it would require some modifications to a
system call. b probably wouldn't require any modifications to non-CKRM
files/dirs. 

	This sort of question would probably come up for any other CKRM
"embraced-and-extended" tunables. Should they use the answer to this
one, or would it go on a case-by-case basis?

I don't think the name matters, as long as the RM code is simplified/unified.
that is, the only difference at first would be a change in name - 
same behavior.

it has to behave as it does now, unless the admin has imposed some 
class structure other than the normal POSIX one (ie, nice pertains 
only to a process and is inherited by future children.)

some interfaces must remain (renice), and if their behavior is implemented
via CKRM, it must, by default, act as before.  other interfaces (say 
overcommit_ratio) probably don't need to remain.

users can only nice up, and that policy needs to remain, obviously.
you appear to be asking what happens when the scope of the old mechanism
conflicts with the scope determined by admin-set CKRM classes.  I'd 
say that nicing a single process should change the nice of the whole 
class that the process is in, if any.  otherwise, it acts to rip that 
process out of the class, which is probably even less 'least surprise'.

I don't see that CKRM should play by rules different from other 
kernel improvements - preserve standard/former behavior when that 
behavior is documented (certainly nice is).  in the absense of admin-set
classes, nice would behave the same. 

all CKRM is doing here is providing a broader framework to hang the tunables
on.  it should be able to express all existing tunables in scope.

On the Zaurus I'm seeing a couple of false "BUG: soft lockup detected on
CPU#0!" reports. These didn't show under 2.6.12-mm1 which was the last
-mm kernel I tested. softlockup.c seems identical between these versions
so it looks like some other change has caused this to appear...

Both of these are triggered from the nand driver. The functions
concerned (nand_wait_ready and nand_read_buf) are known to be slow (they
wait on hardware).

OK, thanks.  We can stick a touch_softlockup_watchdog() into those two
functions to tell them that we know what we're doing.  If you have time to
write-and-test a patch then please do so - otherwise I'll take an untested
shot at it.

I have applied it to my tree. There still is a lot left when I compile
with -Wsign-compare.

All the problems are born here:

struct sym_entry {
    unsigned long long addr;
    unsigned int len;
    unsigned char *sym;
};

I suppose you want sym to be an unsigned char to store the type and to do
the checksum math in there.
And why use a 64bit address in 32bit archs ?. There is no math involved
with 'addr', so you can make it a pointer and let the compiler decide its
size.

Why don't you do something like:

struct sym_entry {
    void		*addr;
    unsigned char	type;
    unsigned short	len;
    union {
	unsigned char	data[KSYM_NAME_LEN+1];
	char		name[KSYM_NAME_LEN+1];
    };
};

Option b) is identify the five lines that do the checksum math and plague
them with (unsigned char) casts...
Will try to do it...

What are you guys talking about?

I've just compiled the current version in -mm with -Wsign-compare and it 
doesn't give me a single warning.

Is my compiler version the problem (3.3.2), or are you testing with the 
old version of kallsyms?

"unsigned char *" is simply the wrong type for mere text strings. "char
*" ist the corrrect one. These are BTW two completely different types
(yes, "char" can be promoted into an "unsigned char" but essentially
these are two completely different types like "int" and "long long *").

Compiler version - zse gcc-4.*.

You're comming really late in this thread :)

The problem is that "sym" isn't really a string. It starts out as a 
string, but as the compression scheme begins to work it just becomes a 
"bunch of bytes" using all the values in the range 0-255 for which 
unsigned char is the perfect type.

Since only the loading of the symbols use string functions, and all the 
compression process treats these as bytes, it seemed better to treat 
them as unsigned chars and just typecast the first few uses.

The union suggested by J.A.Magallon might be a reasonable solution, but 
we only need 4 casts in the 500 lines of code of scripts/kallsyms.c to 
solve all problems, so this seems really overkill.

>>Is my compiler version the problem (3.3.2), or are you testing with the

> Compiler version - zse gcc-4.*.

Yes, I know J.A.Magallon is trying to silence the warnings of gcc 4.0, 
but as I understood it, gcc 3 would also complain of the same problems 
if -Wsign-compare were specified. It was just that gcc4 would complain 
even without -Wsign-compare.

So the question is: is gcc4 complaining about signedness problems that 
gcc3 doesn't, even with -Wsign-compare?

Now that I look at the source, I can see that it must be complaining! 
There are still 3 calls to strcmp that use sym directly, and gcc3 
doesn't say a thing.

I thought that these were already taken care of. In any cased the 
attached patch should fix those and make the code more readable too. 
With this patch we end up only having 2 casts to (char *) in the whole 
source.

Can someone with gcc 4 apply this to the latest -mm and check that it 
fixes everything?

Well, the same issue arised recently somewhere else too on this list and
lots of C programmers (not only beginners) don't know about the 3 char
types as speficied in the C standard.
[ The C standard may have got problems recently with the real world
usinf UTF-8 for a printable character but this must be solved
elsewhere. ]

ACK.

> The union suggested by J.A.Magallon might be a reasonable solution, but 

Syntactically yes. Conceptually no IMHO. sizeof(char) must be ==
sizeof(unsigned char) and must have the same alignment. So a cast seems
to be the simpler and cleaner solution.

AFAIK applies -Wsign-compare in gcc-3 only to pure compares (<, >, ...)
and not assignments/passed parameters too.

As above - this will probably be silently promoted by gcc-3.

Re: 2.6.13-rc3-mm1 compiles unrequested/unconfigured module!

[Helge Hafting]

I usually compile without module support.  This time, I turned modules
on in order to compile an external module.

To my surprise, drivers/scsi/qla2xxx/qla2xxx.ko were built even though
no actual modules are selected in my .config, and the source is
not patched at all except the mm1 patch.

It would be unfortunate indeed since CPU is the first resource that 
people want to try and control.

However, I feel the following are also true:

1. It is still better to have CKRM with the I/O, memory, network, 
forkrate controllers than to have nothing just because the CPU 
controller is unacceptable. Each controller is useful in its own right. 
It may not be enough to justify the framework all by itself but together 
with others (and the possibility of future controllers and per-class 
metrics), it is sufficient.

2. A CPU controller which is acceptable can be developed. It may not 
work as well because of the need to keep it simple and not affect the 
non-CKRM user path, but it will be better than not having anything. 
Years ago, people said a low-overhead SMP scheduler couldn't be written 
and they were proved wrong. Currently Ingo is hard at work to make 
acceptable-impact real time scheduling happen. So why should we rule out 
the possibility of someone being able to develop a CKRM CPU controller 
with acceptable impact ?

Basically, I'm pointing out that there is no reason to hold the 
acceptance of the CKRM framework + other controller's hostage to its 
current CPU controller implementation (or any one controller's 
implementation for that matter).


> Wouldn't that be a rather serious
> problem for many users of CKRM if they wanted to work on mainline
> kernels?

Yes it would. And one could say that its one of the features of the 
Linux kernel community that they would have to learn to accept. Just 
like the embedded folks who were rooting for realtime enhancements to be 
made mainstream for years now, like the RAS folks who have been making a 
case for better dump/probe tools, and you, who's tried in the past to 
get the community to accept PAGG/CSA :-)

But I don't think we need to be resigned to a CPU controller-less 
existence quite yet.  Using the examples given earlier, realtime is 
being discussed seriously now and RAS features are getting acceptance. 
So why should one rule out the possibility of an acceptable CPU 
controller for CKRM being developed ?

We, the current developers of CKRM, hope our current design can be a 
basis for the "one controller to rule them all" ! But if there are other 
ways of doing it or people can point out whats wrong with the 
implementation, it can be reworked or rewritten from scratch.

The important thing, as Andrew said, is to get real feedback about what 
is unacceptable in the current implementation and any ideas on how it 
can be done better. But lets start off with what has been put out there 
in -mm rather than getting stuck on discussing something that hasn't 
been even put out yet ?
