* Documentation: Update documentation regarding --mem-usage' optionBhupesh Sharma2018-04-03
| | | | | | | | | | | | | Earlier patch in this patchset, enables the '--mem-usage' makedumpfile option on arm64 platforms. In addition, I have validated the '--mem-usage' makedumpfile option on several ppc64/ppc64le and s390x machines, so update the 'makedumpfile.8' documentation to indicate that '--mem-usage' option is supported not only on x86_64, but also on ppc64, s390x and arm64 platforms.

* [PATCH v2] Add the --partial-dmesg option to dump only non-cleared dmesgIvan Delalande2017-06-14
| | | | | | | | | | | This option will make --dump-dmesg save only the part of the dmesg buffer since it was last cleared on the crashed kernel (with dmesg --clear and such) instead of the whole buffer since boot or wrap-around. It works on kernels with commit f468908bb55a ("printk: add clear_idx symbol to vmcoreinfo") merged in v4.6 and otherwise will default to the regular behavior.

* [PATCH v3 7/7] mem-usage: allow to work only with -f for kernel version < 4.11Pratyush Anand2017-03-03
| | | | | | | | | | | | | | PT_LOAD of kcore does not have valid p_paddr values for kernel version less that v4.11. Therefore, older kernel will no long work for mem-usage with current makedumpfile code. They can only work when they are patched with fix to "update physical address for kcore ram and text". This patch fixes the makedumpfile so that it does not allow to work older kernel for --mem-usage until someone is sure that kernel is rightly patched and so uses -f in command line. It also updates man page and usage info accordingly. Signed-off-by: Pratyush Anand <panand@redhat.com>

* [PATCH 1/2] Modify the description of the dump level.Atsushi Kumagai2014-11-17
| | | | | | | | | | | | | | | | There are two kinds of dump level related to cache pages as: - Exclude cache pages without private flag (level:2) - Exclude all cache pages (level:4) The former excludes only the cache pages which don't have private flag while the latter excludes all cache pages. However, the man page occasionally make users misunderstood due to the incomplete description, so it would be better to add the description of each base dump level and to unify the expression.

* [PATCH v6 8/8] Add a new interface to show the memory usage of 1st kernel.Baoquan He2014-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently people complained that they don't know how to decide how much disk size need be reserved for kdump. E.g there are lots of machines with different memory size, if the memory usage information of current system can be shown, that can help them to make an estimate how much storage space need be reserved. In this patch, a new interface is added into makedumpfile. By the help of this, people can know the page number of memory in different use. The implementation is analyzing the "System Ram" and "kernel text" program segment of /proc/kcore excluding the crashkernel range, then calculating the page number of different kind per vmcoreinfo. The print is like below: ~$ ./makedumpfile --mem-usage /proc/kcore The kernel version is not supported. The makedumpfile operation may be incomplete. Excluding unnecessary pages : [100.0 %] | ---------------------------------------------------------------------- TYPE PAGES EXCLUDABLE DESCRIPTION ZERO 28823 yes Pages filled with zero CACHE 197932 yes Cache pages CACHE_PRIVATE 15862 yes Cache pages + private USER 30778 yes User process pages FREE 3671105 yes Free pages KERN_DATA 105168 no Dumpable kernel data Total pages on system: 4049668 makedumpfile Completed. BTW, in formal version of kernel which maintainer declares to support after sufficient test, the warning message about kernel version won't occur. Signed-off-by: Baoquan He <bhe@redhat.com>

* [PATCH 1/3] Remove the 1st bitmap buffer from the ELF path in cyclic mode.Atsushi Kumagai2014-06-17
| | | | | | | | | We can create the 2nd bitmap without creating the 1st bitmap by commit 363d53fc8, so we don't need to create the 1st bitmap in cyclic mode in the ELF path since it isn't used.

* [PATCH v2 2/2] Calculate the size of cyclic buffer automatically.Atsushi Kumagai2012-11-22
| | | | | | | | | | | | | | | | | | | | The size of cyclic buffer is set to DEFAULT_BUFSIZE_CYCLIC(1MB) when the size isn't specified. But 1MB is too small for large memory machine and the number of cycle will be so large. As a result, a lot of time will be spend for dump filtering. To resolve the issue above, I add calculate_cyclic_buffer_size() to calculate the buffer size as needed. Concretely, the logic is to choose the lesser value of the two below as the size of cyclic buffer: a. the size enough for storing the 1st/2nd bitmap for the whole of vmcore b. 80% of free memory (as safety limit) calculate_cyclic_buffer_size() uses max_mapnr, so it needs to be done after get_max_mapnr().

* [PATCH v4 1/12] Introduce cyclic mode to keep memory usage constant.Atsushi Kumagai2012-09-06
| | | | | | | | | | | | | | | | | | This patchset introduces new filtering logic called "cyclic mode" as a default. In the cyclic mode, makedumpfile reads regions of a fixed size from /proc/vmcore, analyzes it, and writes pages to dumpfile repeatedly from start of memory to the end. As a result, memory usage will be kept constant regardless of system memory size. However, the cyclic mode has performance issue in the logic to exclude free pages. (I'm going to improve this issue in feature release.) If you feel the cyclic mode is too slow, you can specify --non-cyclic option.
