Hi,
makedumpfile version 1.2.4 is released.
Please test it. Your opinions/comments are welcome.
Changelog:
o Add linux-2.6.24 support.
An old makedumpfile didn't support linux-2.6.24, and it displays the
following message on linux-2.6.24:
The kernel version is not supported.
The created dumpfile may be incomplete.
A new makedumpfile was confirmed that it runs currently on linux-2.6.24,
and it supports linux-2.6.24. So it doesn't display the above message.
o Add xen kernel support to the STDOUT feature (-F option).
This patch was provided by Akio Takebe.

o Fix the method looking for .debug_info section in get_debug_info().
An old makedumpfile didn't quit the loop even if finding .debug_info
section. The bug doesn't affect the program's functionality, but it
should be fixed.
This patch was provided by Nguyen Anh Quynh.
o Fix the problem that -d1 option cannot be specified without -x/-i option.
-d1 option excludes pages filled with zero, and it should be able to run
without -x/-i option.
Explanation of makedumpfile:
To shorten the size of the dumpfile and the time of creating the
dumpfile, makedumpfile copies only the necessary pages for analysis
to the dumpfile from /proc/vmcore. You can specify the kind of
unnecessary pages with dump_level. If you want to shorten the size
further, enable the compression of the page data.
Download:
You can download the latest makedumpfile(ver. 1.2.4) from the following URL.
Details of the change are written on the CVS page of the following site.
https://sourceforge.net/projects/makedumpfile/
Method of installation:
You can compile the makedumpfile command as follows;
1. "tar -zxvf makedumpfile-1.2.4.tar.gz"
2. "cd makedumpfile"
3. "make; make install"
Usage:
makedumpfile [-c] [-E] [-d dump_level] [-x vmlinux] dump_mem dump_file
Example:
If you want to exclude pages filled by zero, cache pages, user pages
and free pages and to enable compression, please execute the following
command.
# makedumpfile -c -d 31 -x vmlinux /proc/vmcore dumpfile
Thanks
