same application code - different behavior with kernels 2.4 vs. 2.6
Hey, I'm playing with a Linux embedded box. Some time ago, we (finally) switched from kernel 2.4.36 to 2.6.18.8. Naturally libc was also upgraded. What have not changed was the sources of the applications: Firefox 2.0 running on top of custom X server. GTK/pango/cairo/etc are also identical in both systems. So far so good, yet we have found out that the kernel/libc upgrade basically broke the customer's code: CSS/Javascript timers driven application, running inside the browser, which started to run much slower, from user experience point of view. Unfortunately, the customer's user experience is extremely important ;) Black box analysis showed differences in system behavior, see bellow. Any idea about what else should be checked are greatly appreciated. And yeah, the final goal is a happy customer. Please share you thoughts - bounce some ideas. Thanks in advance, ~baum - TOP 2.4 The system CPU is 5% idle, utilization is between browser and X server in 60%-40% ratio. 2.6 The system CPU is 80% idle, utilization is between browser and X server in 60%-40% ratio. - STRACE (strace -c -p PID / during 100 secs).

Kernel memory management problem
Guys/Girls/Dudes, I'm working with embedded Linux box powered by 2.4 kernel ( I know :) we are in process of switching to 2.6 ) with 1G physical memory, no swap defined and some slow flash storage mounted. We noticed that if we copy large media file ( 1.4G ) to flash storage filesystem, using wget/sftp/whatever kernel grabs almost all the available physical memory and buffers are not released even after transfer is completed and sync; sync; sync is issued :). It constitutes a problem - applications have no enough memory to run - crash and burn in hell. See bellow memory consumption numbers (top output): Before test start: Mem: 97296K used, 807096K free, 0K shrd, 1732K buff, 54712K cached During/After test: Mem: 897908K used, 6484K free, 0K shrd, 2872K buff, 835088K cached It worth mentioning that probably we see this issue since network IO rate is higher than storage IO rate. I’m not sure which kernel subsystem is memory grabber: VFS buffer cache, storage driver maybe something else? Bottom line is we don’t want to let the kernel to be so memory hungry and it’s desirable to set some reasonable limit on memory usage and thus work around this problem.

To me it's looks perfectly normal:
almost all of your memory is cached.
I.e kernel know, that this memory was read/written to/from file(s)
and if any of this content is needed kernel can provide it without access to
the filesystem (disk, flash, whatever).
But on the other size when kernel ready to give up that memory, when real
need arise.
Thank you for your insight.
Unfortunately this is real problem: if you do something like
while(true) { transfer } then application crashes and burns in hell :)
Nondeterministically - guys researching this issue called it
Heisenbug ( http://en.wikipedia.org/wiki/Unusual_software_bug ) .
There is clear expectation that application should have at least 25 MB
to run in. Hunger of kernel for memory must have hard limits, even if
it means making transfer more slow - which is not a problem at all.

It's your right. The question is how effective it will help to solve your
problem :)
Do you run a standard kernel or a custom one ?
Is your transfer program run alone or there are other applications
running ?
Kernel has parameter, something like total over commit - when
treshold is reached even when there is a lot of FREE memory any single
malloc or mmap will fail.
We're using pretty standard 2.4.36 kernel.
I looked at total over commit, a.k.a. vm.overcommit_memory sysctl parameter.
It's set to 0 by default on my system. From description I've
harvested on Google (http://www.win.tue.nl/~aeb/linux/lk/lk-9.html):
It is described in Chapter: Going in the wrong direction :) on old
kernels. There is also chapter Going in the right direction which
describes newer vm.overcommit_ratio. My kernel does not provide such
interface.
Yet I tried to play with values of vm.overcommit_memory and set it to
1, 2, 80 and did not notice any improvement - free still drops till
about 6MiB. I'm also not sure it is relevant to my case since
transfer application does not grow at all and stays bellow 10MiB, so
it does not malloc() big chunks. I'm getting more and more sure it is
VFS buffer cache problem. For instance quick way to reclaim the cached
memory is removing the 1.4G file from the filesystem.
Yet I've found some patch which looks promising from description point
of view:
http://mailman.uclinux.org/pipermail/uclinux-dev/2007-January/041671.html
I'm not an expert on VM subsystem and not sure it will apply cleanly on 2.4.36
Any thoughts?
Valery.

Oh, but that's just evil, setting RWIN to be a third-level modifier just for
the fun of selecting it as a language switching key, because the binding
selection engine does not understand that it is a modifier. If you would bind
it as something else, that would be nice, but people use ISO_Level3_Shift to
temporarily switch keymaps, and your hack creates a collision.
It is interesting that ISO_Next_Group and ISO_Prev_Group can't be used as kde
modifier keys, for some reason unknown to me. Perhaps, in a world where
modifier keys can be bound to actions, making it impossible to bind the right
key to this action makes sense. Moreover, it is only possible to switch
keymaps in one direction in KDE.
I still hang to my opinion that KDE keyboard switching is a mess between xkb
and modmap, thus, I use xkb and ignore KDE keymap switching altogether.

Re: Visual diff tool for patches.
Did not see you mentioned meld specifically. Anyway I could sugest the following procedure. You could prepare two copies of the source tree: pristine and modified, where modified is pristine with patch applied. Then fire up meld (or any other merge tool) and just apply/move changes one by one from modified to pristine. Hope it helps.

Re: Build processes
Tzahi, I could recommend classic paper Recursive Make Considered Harmful http://aegis.sourceforge.net/auug97.pdf It describes a way to build Makefiles with automatic dependencies, meaning no separate make dep target. Non-recursive Makefile builds *exactly* needed files and only them. Saves tones of time and resulting binaries always consistent, meaning no need to do make clean just to be sure. The main idea behind it *not* using industry standard practice of main Makefile recursively running make in subdirectories. Instead single Makefile should be used which includes subdirectory's Makefiles. It makes a difference, because this way make program has a full picture of project's dependency graph. This model is clearly a beauty if you ask me. It is simple and it works. Alexander Indenbaum On 9/27/06, Tzahi Fadida [EMAIL PROTECTED] wrote: Hi, I wish to learn more about build process/es.

But the danger that I'll try to use the key on another linux system presenting the same problem is very low in my case... I shall recompile the kernel, instead. Now, in the documentation coming with the kernel source they recommend to use GCC vesrion 2.95.3. That is teribly old, and probably hard to get. I guesss the documentation is not updated. I recall that there was a time, 2 or 3 years ago when they recomended to use the old 2.95.x version of gcc to compile the kernel, while using the newer version for everything else. This is, probably, long time passe. But, to be on the safe side, what is the present recommendation? Indeed README still talks about 2.95.3, which was latest stable many years ago :) When you're not sure which version to use the best practice is to use default gcc which came with your distribution: it should be compatible with your kernel. My 'gcc -v' reports version 3.4.5 and produced working 2.6 kernel images. Another advice is to reuse existing kernel configuration from /proc/config.gz, just change relevant kernel option and use 'make oldconfig' build procedure.

[OT] about birds in state of art network technology
Hello,
This is OT story from real life and it's still rolling.
A couple of days ago I was reading an article comparing Linux and
Solaris driver models. This article was recommended by Sun as
introductional reading for driver developers and was published on
April 1 2005 at OpenSolaris.org site. While reading I noticed a
factual error and felt really proud for myself, so I wrote a
correction letter to the respected author:
Max,
I was reading your article Inside OpenSolaris: Introduction to
Solaris Drivers at
http://opensolaris.org/os/article/2005-03-31_inside_opensolaris__introduction_to_solaris_drivers/
When you're discussing differences between Linux and Solaris device
driver models you're stating:
Linux uses the same names for devices regardless of their location
(and regardless of the hardware). For instance, Linux disks are
/dev/hda, /dev/hdb, etc., regardless of whether the disk is IDE or
SCSI.
Example you have used seems to me to be inaccurate:
1. IDE disk on Linux named /dev/hdX, from other hand SCSI disks
are /dev/sdX.
2. When talking about IDE disks, device names are determined by their
location/channel:
* hda - primary controller master
* hdb - primary controller slave
* hdc - secondary controller master
* hdd - secondary controller slave
This meens if I move, for example, disk from primary to secondary
controller, its device name will change.

Max admitted an error, but his answer seemed not serious enough to me,
so I wrote a sarcastic reply:

Hi,
This mistake has been pointed out to me, but I have no easy way to

One other mistake which has been pointed out to me

Have not read that article pearl yet.
I also expect that
over time there will be things which change in both OSes...
Well, maybe indeed it is not coincidence that your article is dated
April 1 :)

Thanks,

The strangest thing, Max answered to me today again as if he did not
get it at all !!!
He was asking why April 1 ?
So I had to make it crystal clear: it is all about birds in state of
art network technology:
On 3/19/06, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote:
The extent-based file system stuff is in a different article.
And my comment about things changing in both OSes was also meant
to refer to a different article.
That sounds very interesting. Could you give me a link to this article?
So, what is it about the
driver article that makes you think a publishing date of April 1
is not a coincidence?
April 1 is a day that traditionally marked by publishing revolutionary
articles. Usually about birds in state of art network technology.
Most famous are:
* RFC 1149 - Standard for the transmission of IP datagrams on avian carriers

Re: problem in top utility
Hey, Some unaccounted CPU cycles are consumed for handling software and hardware interrupts and some for managing internal kernel structures like network stack to push packets around or other kernel responsibilities like scheduling or filesystem. The point is that kernel part of CPU pie could not be always mapped to a specific process, that's why benchmarks for IO intensive software systems generally speak about total CPU utilization which could be calculated as 100% - idle%. Totally unrelated but very useful benchmark metric is user/system CPU ratio for a specific process as a function of system load. Systems suffering from contention problems demonstrate good ratio of 80% user 20% system for low-mild load and could reverse and degrade to 20% user 80% system ratio for high load. Naturally such systems do not scale well and perform badly under heavy load.

[OT] Memory allocation in multi-threaded program on multi-proccessormachine
Hi! We have problem with program which fails to utilize all the CPUs on multi-proccessor machine. We suspect that all the threads wait on same mutex when they allocate memory since heap is shared. Is this true? How it can be solved?

Linking Q. - merging global symbols.
Hi!
We develop product using Linux / GCC.
We have problems with run time linking with dll ( .so ) using
dlopen/dlsym. The problem is that global symbols of program and library
with the same name are getting merged when dlopen() executed ( having
global symbols as a bad design is another question :{) ) As result API
function from dll call causes changing of internal data in main program
which is obviously is not desirable at all.
How it can be prevented?

I have a machine installed with RH6.0 that has the who command behave strangely: I only see people that are rloged in to the machine, or if I login from one of the virtual consoles. No "xterm" or any other kind of X terminal I tried shows up in the "who" list. I compared some file permission to another RH6.0 machine we have (where who works fine) and saw no difference. I mainly looked at /var/run/utmp and /var/log/wtmp On plain XFree xterm you have flag: -ut This option indicates that xterm shouldn't write a record into the the system log file /etc/utmp. +ut This option indicates that xterm should write a record into the system log file /etc/utmp.

[off topic] Solaris x86 2.7 and Western Digital 8.4G IDE HD
Hi! I just bought Western Digital 8.4G IDE HD with intention to install Solaris on it. I installed it as secondary master in addition to another HD + CD on primary ide controler. During Solaris installation boot kernel reported warnings about timeout on new HD. Afterwards installation program failed to create fdisk partition. Disk seems to work with Linux and NT. No warnings during boot up. I created couple of fdisk partions, scandisked and fscked it before and after I wrote and read old disk's contents on it with both OSes. All without any visibale problem.
