Hello,
makedumpfile version 1.6.2 is released.
Your comments/patches are welcome.
Main new feature:
o Support for sparc64
- sparc64 is supported from this version, it's tested on kernel-4.1.12.
o Add new option for --dump-dmesg
- Introduce the new option "--partial-dmesg", it can exclude the buffers
cleared by "dmesg --clear" while the current --dump-dmesg always extracts
the whole ring buffer.
o Support new kernels
- The supported kernel is updated to 4.11 in this version.

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 from the following URL.
Details of the change are written on the git 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-x.y.z.tar.gz"
2. "cd makedumpfile-x.y.z"
3. "make; make install"
Usage:
makedumpfile [-c|-l|-p] [-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 /proc/vmcore dumpfile
Thanks
Atsushi Kumagai
