|

Note that there is an alternative form in which to specify a crashkernel
|
||||
memory reservation, in the event that more control is needed over the size and
|
||||
placement of the reserved memory. The format is:
|
||||
|
||||
crashkernel=range1:size1[,range2:size2,...][@offset]
|
||||
|
||||
Where range<n> specifies a range of values that are matched against the amount
|
||||
of physical RAM present in the system, and the corresponding size<n> value
|
||||
specifies the amount of kexec memory to reserve. For example:
|
||||
|
||||
crashkernel=512M-2G:64M,2G-:128M
|
||||
|
||||
This line tells kexec to reserve 64M of ram if the system contains between
|
||||
512M and 2G of physical memory. If the system contains 2G or more of physical
|
||||
memory, 128M should be reserved.

Similar to raw partition dumping, you can format a partition with the file

it should be at least as large as the amount of memory in the system. Assuming

/dev/sda3 has been formatted ext4, specify 'ext4 /dev/sda3' in kdump.conf,

Subject: [PATCH] handle !SPARSEMEM_EX properly.
|
||||
X-Git-Url: http://makedumpfile.git.sourceforge.net/git/gitweb.cgi?p=makedumpfile%2Fmakedumpfile;a=commitdiff_plain;h=27b71566ec11128c5b061a350e467546f2d26be6
|
||||
|
||||
[PATCH] handle !SPARSEMEM_EX properly.
|
||||
|
||||
In !SPARSEMEM_EX case, the symbol mem_section points a array of struct
|
||||
mem_section, doesn't point a array of pointer to mem_section[], so I
|
||||
think the check:
|
||||
|
||||
if (!is_kvaddr(mem_sec[SECTION_NR_TO_ROOT(nr)]))
|
||||
return NOT_KV_ADDR;
|
||||
|
||||
in nr_to_section() is not a valid check in this case.
|
||||
|
||||
To make the matters worse, if CONFIG_CGROUP_MEM_RES_CTLR is enabled, the
|
||||
end of struct mem_section is padded with 0.
|
||||
|
||||
So, reading mem_section by "rd" of crash will look like:
|
||||
|
||||
crash> rd mem_section 128
|
||||
c08b71e0: c9002003 c9001200 f7000000 00000000
|
||||
c08b71f0: c9002003 c9001260 f6980000 00000000
|
||||
c08b7200: c9002003 c90012c0 f6300000 00000000
|
||||
c08b7210: c9002003 c9001320 f5c80000 00000000
|
||||
|
||||
This means nr_to_section() will return 0 when "nr" is 3,7,11,... because
|
||||
it meets the condition(mem_sec[SECTION_NR_TO_ROOT(nr)] == mem_sec[nr]
|
||||
== 0 == !is_kvaddr).
|
||||
|
||||
As a result, mem_map for section 3,7,11,... cannot be handled properly.
|
||||
|
||||
This patch is a fix for this problem. nr_to_section() will check "addr"
|
||||
by is_kvaddr() later anyway, so this patch just removes the problematic
|
||||
check.
