Summary: testing trunk head toolchain on trunk head kernel would have init make kernel panic

Details:

testing trunk head toolchain on trunk head kernel would have init make kernel panic.

when testing comes to libstdc++/libmudflap, it would stuck and find that trunk head kernel has been make panic and restarted.

--- Mingquan Pan 2009-09-02 00:03:05

Since I can test trunk toolchain with 09r1 branch head kernel, so it should be

the problem of uclinux and move it here.

--- Mingquan Pan 2009-09-09 06:37:35

I try to reproduce this issue with libstdc++ testing on hardware-flat.

In this testing, with linux , uclinux-dist :

6645 8286 fails

6640 8280 works

It fails like the kernel works abnormal and would print out dump info even run

simple command like "ls", but not panic yet.

And this issue may be related to the binary format. If I build the kernel into

fdpic format, it could finish the libstdc++ testing in hardware-flat even in

trunk head kernel.

--- Mingquan Pan 2009-10-26 03:13:02

It looks using the trunk head kernel to test 4.3 toolchain still fails with

kernel panic taking place in the middle of testing.

--- Graf Yang 2009-12-08 08:10:46

There are more memory fragments since kernel 2.6.30 (commit 6645 on kernel

trunk). This caused busybox fail to execute and maybe panic because of stack

destroyed.

The fastest way to reproduce it is to testing the libstdc++(cd

toolchain/buildscript-experimental; ./toolchain-regtest -s /opt/bfin/toolchain

-o /opt/uClinux/bfin -b /tmp/ -t uclinux -T 10.100.4.37 -a -L libstdc++),

continues memory allocation fail(executing the shell, or rm) will occur in 10

minutes.

The 2.6.28.10 kernel have not this issue.

--- Robin Getz 2009-12-08 20:40:01

So -- is the 2.6.30 kernel fragmenting memory? or not re-combining things as

agressively as the 2.6.28 kernel did?

Either could be the problem - and it might help to figure out what is causing

the failures if we know which was the actual issue...

--- Graf Yang 2009-12-08 22:00:57

In my testing, only the kernel is different, one is svn 6644, other is svn

6645.

I'm focusing on the mm/page_alloc.c and trying to find out the fragment reason.

--- Robin Getz 2009-12-08 22:15:22

I understand that.

The question I asked was - is the difference the fragmentation, or the

difference is the re-combining.

Both could fragment the same during run time, but if 2.6.28 was more aggressive

on re-combining small pages into large pages - then eventually 2.6.30 will fail.

(even though the problem isn't with fragmentation - it is with putting things

back together)....

--- Graf Yang 2009-12-09 02:33:01

How to estimate the allocation fragmentation or re-combining fragmentation?

It's an accumulated result after hundreds of allocation/freeing.

I saw there are more freelists with little order in the kernel 2.6.30 than that

in the kernel 2.6.28 after it ran toolchain testing the same time long.

I suspected that the fragment is caused by other portion of kernel, instead of

page_alloc.c, because there are not modifications that changed the page

allocation rule between svn6644:6645 to my thinking.

Grace,

as a temporary workaround, you can configure the kernel to use SLOB, or trying

the following patch,

The fragment is caused by the default trim behavior of do_mmap_private().

We can turn off it for the testing cases that kernel will run a long time and

need to execute thousands of programs.

Method A.

Linux Kernel Configuration -->

Blackfin Processor Options -->

Yes, by disabling this item, now the trunk head toolchain can finish testing by

running on trunk kernel. Close.

--- Mingquan Pan 2010-01-25 01:26:32

This issue still frequently shows up now on trunk head kernel in current

toolchain testing at libmudflap.

Besides BF561, did this issue exist on BF537 still?

--- Mingquan Pan 2010-02-02 01:14:17

Yes，it happens to BF537 stamp and other boards, too.

--- Mingquan Pan 2010-02-04 04:22:21

After revert the changes to traps.c [#8266], the toolchain test can finish now.

So close for now.
