RFC 1/1 makedumpfile-1.1.4-rc: ia64 DISCONTIGMEM support

Hi,

The attached patch is for the development, and it isn't stable yet. This patch can be applied to makedumpfile version 1.1.3. If you find some problems in this patch, please let me know. If there aren't any problems, I will release a new makedumpfile by next weekend.

Changelog:
1. Add __FUNCTION__ to ERRMSG.
The function name is added to ERRMSG.
2. Add ia64_vtop().
The translation function from a virtual address to a physical address is added for ia64.
The patch was provided by Bernhard Walle.
3. Add ia64 DISCONTIGMEM support.
A new makedumpfile supports ia64 DISCONTIGMEM.
4. Cleanup README.
The destination of BUG REPORT is changed to kexec-ml. The item REQUIREMENTS is added.
5. Fix DISCONTIGMEM bitmap.
This patch fixes the problem that it cannot output the part of bitmap on DISCONTIGMEM kernel.
6. Fix ELF output with overlapping sections.
The patch was provided by Bernhard Walle.

Thanks
Ken'ichi Ohmichi

Hi,

I did that, but I still cannot build a kernel, although the problem is different now. The build fails with:

Inconsistent kallsyms data
Try setting CONFIG_KALLSYMS_EXTRA_PASS
make: *** [vmlinux] Error 1

even after I set/enable CONFIG_KALLSYMS_EXTRA_PASS.

Have you tested this on x86_64?

Thanks.

Makefile installs ld command etc. and they influence kernel build. We installed elfutils-0.125 not by 'make install' but by procedure written at README of makedumpfile-1.1.6 in RHEL5.0 environment. Please uninstall elfutils-0.125 and elfutils-0.128 and try the above procedure.

The procedure is as follos:

     # tar -zxvf elfutils-0.125.tar.gz
     # cd elfutils-0.125
     # ./configure
     # make
     #
     # mkdir /usr/local/include/elfutils/
     # cp ./libdw/libdw.h   /usr/local/include/elfutils/libdw.h
     # cp ./libdw/dwarf.h   /usr/local/include/dwarf.h
     # cp ./libelf/libelf.h /usr/local/include/libelf.h

Sorry about this. Above was with the distro-installed 'ld' instead of the one built from elfutils-0.125. When I correct this, build fails like this:
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CHK     include/linux/compile.h

could this be elfutils-0.125.tar.gz or later?
I.e., is there something special/specific about elfutils-0.125 ?
It's a bit difficult to find 0.125 on the internet...
The reason that I ask the question(s) is that after I build elfutils-0.128 and then do 'make install', I can no longer build a kernel, i.e., kernel 'make' has errors, like:
  CC      init/main.o
  CC      init/do_mounts.o

Hi tachibana-san,

I have makedumpfile filtering working now. Much thanks.

Examples of filtering on a 1 GB x86_64 system, booted with "crashkernel=64M@16M" and then crashed (sysrq-c).

Various makedumpfile -d values and their results:

makedumpfile -d 1 -E -i vmcore.info vmcore.002 dump002.omit.zero makedumpfile -d 17 -E -i vmcore.info vmcore.002 dump002.omit.zero.free makedumpfile -d 23 -E -i vmcore.info vmcore.002 dump002.omit.zero.free.all.cache makedumpfile -d 31 -E -i vmcore.info vmcore.002 dump002.omit.all

Interesting. Even after filtering all, dump file size is 429 MB. Given this system has got 1GB of memory, so file size reduction is about only 55%. Wondering what kind of kernel data is in there. Can something else also be filtered out.

Thanks
Vivek
