Supporting more kernels. + 2. Fixing the report message. + - Now, it sometimes counts the number of free_pages duplicating zero-pages + if creating an ELF dumpfile. + - The cyclic mode will show incorrect and many progress indicator. + +* NOTE + 1. A vmcoreinfo file should be generated by the makedumpfile which is used + for dump filtering. If installing the latest makedumpfile, the vmcoreinfo + file should be regenerated by it. Actually, makedumpfile v1.2.0 or later + cannot work by vmcoreinfo file which is generated by v1.1.9 or before. + + 2. If using linux-2.6.24 and kexec-tools-testing-20061214, /proc/vmcore + contains vmcoreinfo data. So it is possible to create a dumpfile without + -x option (or -i option) like the following: + # makedumpfile -d 31 /proc/vmcore dumpfile + + 3. On makedumpfile-1.2.5 or before, both '--xen-syms' and '--xen-vmcoreinfo' + excluded Xen user domain pages. Since makedumpfile-1.2.6, '-X' option + have been added for excluding Xen user domain pages, and these options + does not exclude Xen user domain pages. So user should specify '-X' + option for excluding Xen user domain pages. + +* FAQ + 001: If installing elfutils-0.137 into older elfutils by the above way, the + following problem happens sometimes. If seeing, try to enable LDFLAGS + comment (-L/usr/local/lib -I/usr/local/include) in Makefile. + + $ make + [..] + /tmp/ccXQtvnZ.o: In function `process_module': + /makedumpfile/makedumpfile.c:1387: undefined reference to `dwarf_getelf' + collect2: ld returned 1 exit status + make: *** [makedumpfile] Error 1 + + 002: makedumpfile is compiled with -static option, because the command should + run while the second kernel, which may not mount root filesystem and may + not contain dynamic library files, is running. + If the dynamic library files, which are needed by makedumpfile, exist + while the second kernel is running, we can use dynamic libraries by + "LINKTYPE" parameter. + + $ make LINKTYPE=dynamic + + This is a workaround for some linux distributions which does + not contain static library files needed by makedumpfile. + + +* REFERENCES + https://sourceforge.net/projects/makedumpfile/ + http://lists.infradead.org/pipermail/kexec/ + https://lists.linux-foundation.org/pipermail/fastboot/ + +* BUG REPORT + If finding some bugs, please send the information to the following: + Kazuhito Hagio <k-hagio@ab.jp.nec.com> + kexec-ml <kexec@lists.infradead.org> + |
