| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | display_header() code to parse meminfo as is was buggy: - uninitialized variables were used if meminfo was not as expected - meminfo parsing failed on new kernels (3.14+) as new field 'MemAvailable' was introduced between MemFree and Buffers - shared memory was handled only for ancient kernels (2.4.x and earlier) as result Buffers and shared memory fields were shown with bogus values on current kernels. The new code does not try to parse the old style summary header, as the separated fields are always present (it saves code size). Additionally, both Shmem (2.6+) and MemShared (2.4 and earlier) fields are now parsed and summed for shared memory usage; as only one of them exists depending on kernel version. display_topmem_header() parses also meminfo so this makes it use the same code for code shrink. function old new delta display_header - 681 +681 display_topmem_process_list 465 684 +219 parse_meminfo - 189 +189 static.fields - 106 +106 static.match 132 - -132 .rodata 120254 120117 -137 display_topmem_header 513 - -513 display_process_list 1705 667 -1038 ------------------------------------------------------------------------------ (add/remove: 3/2 grow/shrink: 1/2 up/down: 1195/-1820) Total: -625 bytes Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* pmap: new applet. +1k.Alexander Shishkin2010-08-281-8/+8
| | | | | | | | | | | | | | | | | | | pmap is a tool used to look at processes' memory maps, normally found in procps package. It provides more readable and easily sortable output (one line per mapping) from maps/smaps files in /proc/PID/. This would help in debugging memory usage issues, especially on devices where lots of typing is not a viable option. This patch does'n implement -d and -A command line options of GNU pmap, since those are not that must have features and I was afraid of going blind from looking at its code. The implementation takes smaps scanning part out of procps_scan() function and moves it into procps_read_smaps(), which does more detailed processing of a single PID's smaps data.
