- Added the POSIX message queue implementation.  We're still stitching
  together a decent description of all of this.  Reference information is at

	http://www.mat.uni.torun.pl/~wrona/posix_ipc/
 and
	http://www.opengroup.org/onlinepubs/007904975/basedefs/mqueue.h.html

- A fair amount of work against the page reclaim code.  Mainly
  reorganisation and simplification of various little glitches.  This means
  that a few of the optimisations which were in 2.6.3-mm4 were broken and
  were dropped.  But this is a better basis upon which to reintroduce them.

  Performance, however, seems similar to 2.6.3-mm4 in a few tests. 
  Inter-zone balancing is much better than 2.6.3 but still could be improved a
  little.

  Slab reclaim balancing is improved, however with some (artificial)
  workloads slab is still being a problem because of tremendous internal
  fragmentation problems: 6% occupancy of the pages which are allocated to
  dcache, for example.  More work is needed to account for this.

  I tested the swapout code with 7.2G of tmpfs pagecache on a 7G machine. 
  The rotate_reclaimable_page() logic seems to work fine here - only 200M of
  memory was added to swapcache and was swapped out.  

- Plus the usual various little fixes and cleanups.

- The contents of the broken-out/ directory are now available in the
  2.6.4-rc1-mm1-broken-out.tar.gz file.  This includes the `series' file
  which describes the patching order.

  People who are using patch-scripts can recreate the patching machinery by
  doing:

	cd /usr/src/linux
	tar xfz ~/2.6.4-rc1-mm1-broken-out.tar.gz
	mv broken-out/*.patch patches
	mv broken-out/series .
	for i in $(cat-series series)
	do
		pcpatch $i
	done
	rmdir broken-out



Changes since 2.6.3-mm4:

 bk-acpi.patch
 bk-alsa.patch
 bk-arm.patch
 bk-driver-core.patch
 bk-ieee1394.patch
 bk-netdev.patch
 bk-scsi.patch

 Latest versions of various external trees.  bk-i2c.patch was dropped
 pending it getting its lmsensors act together.  And bk-input was dropped
 because it was old and nobody will tell me the input project's bk URL.

This has been rejected on linux-scsi a few times.  Don't use include/scsi/

so the situation is even more clear thæn the general you should not include

hm, OK.  If it works in 2.4 and doesn't work in 2.6 I'd consider that a
regression.  And as the fix is so trivial, I'd consider failure to fix it
as pure dogmatism.  But whatever, I'm utterly bored of this discussion. 
Consider it dropped.

Thank you Andrew.

All these changes are nicely broken out, and they all look good. 
vmscan-control-by-nr_to_scan-only.patch and
vmscan-balance-zone-scanning-rates.patch are almost exactly what
I have here.

I had one addition which is to use a "refill_counter" for inactive
list scanning as well so the scanning is batched up now that we don't
round up the amount to be done. No observed benefits, but I imagine
it would lower the acquisition frequency of the lru locks in some
cases?

kswapd-avoid-higher-zones.patch looks good, and should solve the
incremental min problem which my solution didn't.

Should I start testing again, or are you still doing more to vmscan?
Nikita's dont-rotate-active-list.patch looks to be the only major
casualty. I found this patch pretty important, so I will definitely
like to demonstrate its benefits. One question remains, would you
accept the patch in its current form?

Might do, yes.

Also I think you did some work on the inactive-vs-active list balancing?  I
have spent precisely zero time looking at or working on that since
2.5.nothing and it's entirely possible that it is doing something
inappropriate.

>  Should I start testing again, or are you still doing more to vmscan?

Now would be a good time.  The only thing I'm likely to look at in the next
several days is accounting for the slab fragmentation.  My current thinking
is to solve that by making slab account for the number of objects and the
number of pages, and to use that in shrink_dcache_memory(), so it doesn't
touch vmscan.c at all.

We should bring that back for testing, please.  I need to sit down and
think a bit more about test suites which replicate workloads which we care
about before making any decisions.

One point I would make is that if a workload is only achieving 5% CPU
anyway, we shouldn't optimise for it.  Sure, it's nice to be able to get it
up to 7% but it is much more important to get the 50% CPU workload up to
70%.  The 5% problem is a fiscal one, not an engineering one ;)

My thinking is to go by number of pages. Then you get to tell the
shrinker: we scanned this many pages of LRU, so please scan an
equivalent percentage of slab *pages*.

You can then translate this to number of slab objects before scanning.

Oh, apart from that, there is still one thing that I'm not sure is
correct about slab scanning... we scan slab in response to scanning
a part of the inactive list, but we apply this pressure as if it
were a ratio of active + inactive lists.

This will cause slab to be scanned less, but my main worry is that
it makes slab scanning behaviour dependant on the ratio of active to
inactive list size: the bigger your active list, the less slab will
be scanned which I think is silly. But I might be wrong.

Just so I'm not misunderstood, I must add that I found Nikita's
patch to definitely help light and medium swapping kbuild runs.
The fact that it *really* helped heavy swapping is a bonus.

But I agree that we need more meaningful tests too. Maybe things
like overloading apache or a mail or database server might be
interesting.

The metric which we need to be balancing on here is

	(probability that the object will be needed again) *
	(number of seeks to reestablish the object) /
	(size of object).

The first two factors are wildass guesses.  I figure a pagecache page is
worth maybe 1/8th of a seek and an inode is worth, umm, more than that. 
Maybe half a seek?  Our accounting for this is currently way off and needs
to be tuned up.



One big problem with implementing slab balancing is that the inode cache is
a separate slab per filesystem, so any fancy accounting of icache requires
visits to all filesystems.

Now it could well be that inode_unused is a complete waste of space.  After
all, these are inodes whose dentries have been reaped - it is unlikely that
they're much use.  And it could be that their backing block is still in
pagecache anyway.

So if getting the dcache accounted for is not sufficient then it might be
necessary to either shrink the heck out of inode_unused of just kill it
altogether.

I can confirm that basic functionality is there. Both blocking and
nonblocking operations work as advertised. Queue properly blocks when full
or empty.

mq_timedsend does not wait, it immediately returns ETIMEOUT with the queue
is full:

         struct timespec ts;
         ts.tv_sec=1;
    	 ts.tv_nsec=0;
         sprintf(msgptr,"%05d %s",c,stime);
	 
         if ( mq_timedsend(mqd,msgptr,msglen,msg_prio, &ts) )
	 {
	    perror("mq_send()");
	      break;
	 }

results in:

$ ./mqreceive /Q32x128
1: priority 0  len 64 text 00001 Mon Mar  1 12:20:11 2004  
$ ./mqreceive /Q32x128
1: priority 0  len 64 text 00001 Mon Mar  1 12:20:11 2004  
$ ./mqsend  /Q32x128
$ ./mqsend  /Q32x128
$ ./mqsend  /Q32x128
mq_send(): Connection timed out  <- immediately

Queue is in blocking mode.

I would very much advise Michal and Krzysztof to add some basic examples to
their page. I had to scour the internet to find some working code.

This is one of the few sites that allow you to test the posix message queue:
http://www.ac3.edu.au/SGI_Developer/books/T_IRIX_Prog/sgi_html/ch06.html

The examples there add /var/tmp/ to the queuenames, with linux, posix queues
need to have a name that starts with /.

Mounting the queuefs works but the fs, confusingly, is called mqueue and not
mqueuefs.

Otherwise sound work! PowerDNS really wants posix message queues, right now
we fuddle along with semaphores and locks.

Thanks,
Bert.

It _should_ return immediately. mq_timedsend timeout must be given as 
absolute value, so if you want to have one second timeout from now,
you must do:

	ts.tv_sec = time(NULL) + 1;
    	ts.tv_nsec = 0;

And I don't have idea why POSIX defines timeout as absolute not relative 
;-).

Thats right. The above problem also shows that such examples can be 
usefull. We are just now updating man pages for the library (there are 
some obsolete informations) and I will prepare some well commented programs.

As proc or msdos. Of course it can be changed if more people will want 
'fs' suffix. Menuconfig help gives proper name.

Re: 2.6.4-rc1-mm1

Hi,

has anything changed with C1 halt? I mean it seems that CPU Disconnect 
doesn't get called (Though I enabled it), as with 2.6.3-mm4 (yesterday 
and today going back) my idle temps are about 46-47°C. Now with 
2.6.4-mm1 they went up to 50-52°C.

Using same config. I attached mine for 2.6.3-mm4.

I guess it is some sort of ACPI issue? Aside from the temp rise, I 
haven't noticed any regression. I will try 2.6.4_rc1-mm1 later again, to 
  verify my observation. Anything else I could check?

bye,

Prakash

Hmm, today I went back to 2.6.4-rc1-mm1 and everything seems to be

But the glibc headers don't describe 2.6, do they? Don't work with 2.6?
We went around with this for cdrecord unless I misread which headers are
involved.

It's not reasonable to expect people to rebuild glibc for each kernel,
even if it is "the right thing to do" in some purist sense. It would be
better to have something like user header in the kernel for just the
interface, and have the kernel include start by pulling in the user
header and then adding things the user doesn't need.

Changes between kernel series are always unpleasant during the time when
people have to boot back and forth, we should think about a better way
to do this for 2.7.

Ok, its me again. So now I was running 2.6.4-rc1-mm1 today and the 
rratic behaviour came again, ie, idle temps went high. Strange enough 
this only happens after some time.

Comparing dmesg from both, I see this as major differnece: With latest 
mm-source the as scheduler gets used, though I set elevator=cfq in the 
kernel line. So either you removed cfq or it doesn't get selcted and 
maybe anticipatory causes the temp rise?

Well, I will test as scheduler with 2.6.3-mm4 tomorrow and report back

Prakash

The CFQ elevator is not present in Linus's tree.

So the kernel picked the anticipatory scheduler instead.

Aargghh, something seemed to have gone wrong on patching to the latest 
mm kernel then. *blush*. Well, I'll try again...
