2.5.54-mm3

[Andrew Morton]

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.54/2.5.54-mm3/

Several patches here which fix pretty much the last source of long
scheduling latency stalls in the core kernel - long-held page_table_lock
during pagetable teardown.

The preemptible kernel now achieves around 500 microsecond worst-case
latency on a 500MHz PIII (with a slow memory system).  This is about as
good as the 2.4 low-latency patch.  Maybe better.

This is with ext2, and only with ext2.  Other filesystems need work
to reach that level of performance.

Non-preemptible kernels will benefit as well.  This sort of means that
preemptibility is only really needed for specialised multimedia/control
type apps.   Opinions vary ;)

Filesystem mount and unmount is a problem.  Probably, this will not be
addressed.  People who have specialised latency requirements should avoid
using automounters and those gadgets which poll CDROMs for insertion events.

This work has broken the shared pagetable patch - it touches the same code
in many places.   I shall put Humpty together again, but will not be 
including it for some time.  This is because there may be bugs in this
patch series which are accidentally fixed in the shared pagetable patch. So
shared pagetables will be reintegrated when these changes have had sufficient
testing.

Hugh, could you please closely review these changes sometime?   Thanks.

That stinks...it don't work in .54 and I'd likem to have my automounter
functioning again. Oh well it *is* 2.5.

Also for some reason I always have to do a "touch /fastboot" and boot in
rw mode to boot the kernel. The kernel fails on remouting fs in r-w mode.
X also don't work saying /dev/agpgart don't exist even though it does and
I saw it. agpgart module is loaded..maybe it would work as built into the
kernel? .config attached.

autofsv4 has been working fine across the 2.5 series.  You'll need to
send a (much) better report.

Many more details are needed.  Sufficient for a developer to be able to
reproduce the problem.

You could try statically linking it, yes.  More details are needed,
such as a description of what hardware you have and what driver you're
using.

I don't really know what the problem is..everything seems to be working
right except when it goes to mount the system from ro mode to rw mode.
Therefore well everything goes down hill after that. I looked through the
/var/log/messages and all those files but nothing specific to the problem.
If I disable fsck and append rw mode kernel boots fine. One minor note, boot
also fails during Mounting other filesystems and gives the typical mount
error about bad superblock, or to many mounted filesystems. My .config was
attached before(?) and that's all I have..anything paticular you are looking
for?

I have a i810 Intel graphics card/motherboard, intel celeron 1.06 GHz
processor, and agp 3 enabled, could that be the problem? I have enabled the
intel i810 driver in the graphics area as you can see in the .config. The
intel driver seems to be enabled fine as in the Xfree/GDM log it says
something about Intel. Only error is it can't find device /dev/agpgart even
though it *is* there. Any more info you would need?

Your .config was not attached.

There is a devfs mounting problem in 2.5.54.  If you're using devfs
you may find that
http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.54/2.5.54-mm3/broken-out/devfs-mount-fix.patch

The device node exists in /dev.  It sounds like no kernel driver
has registered itself against tht node's major/minor.   Make really
sure that you have compiled the appropriate driver for your hardware;
things may have changed.  All else fails, send lspci and dmesg output
to this list and/or davej@codemonkey.org.uk

.config is now attached and no, I am not using devfs.

I also attached the dmesg output from 2.5.54. Hope that helps. Sometime
tonight/tomorrow I will reboot 2.5 and attempt to get the lspci output for
the list.

Hey Andrew,

I changed some options in the filesystems (only) category. I seemed to
have been able to reproduce my oops report that I got from the very
beginning and was forced to basically do a minimized config. This time
the oops didn't flood my screen so I was able to get it. I hope the oops
report and the new .config will shed some light on this annoying
problem.

Re: 2.5.54-mm3

I use an IBM X-30 Laptop, based on an i830-Intel Chipset, and experience 
similar problems.
Once or twice a week I get a ro-root filesystem when booting. In that 
case dmesg shows
the line "Trying to unmount old root ... failed"

If I do a 'mount -o remount /' and then a 'rm /dev/null; mknod -m 666 
/dev/null c 1 3' everything
reverts back to normal.

I currently run a SuSE 8.0 Kernel under ext2 - .config, dmesg and lspci 
-vv are attached .
Since I have experienced the problem also with ext3, reiserfs on SuSE 
8.0 and 8.1 kernels
the problems seems to be independent of the filesystem used. I don't 
have a clue what to do next.

Any Ideas?

Michael

Yes. I am always the one getting weird problems :)

It seems to me that the patch you pointed here doesn't include the latency
instrumentation.

Where it is the needed instrumentation to meassure it?

In http://www.zip.com.au/~akpm/linux/ the are no timepeg/intlat patches for
2.5...

No, it doesn't.  You can monitor the latency using realfeel or realfeel2
from http://www.zip.com.au/~akpm/linux/amlat.tar.gz

But that won't tell you _why_ large latencies are occurring.   For that,
you'll need to apply
http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.54/2.5.54-mm3/experimental/rtc-debug.patch
and run `amlat'.  This combination will spit out stack backtraces whenever
there is a 2 millisecond scheduling overrun.

That's not suitable for this work.  intlat is OK for locating and
measuring interrupts-off code paths.   But it's a bit hard to drive.
