* | lscpu: fix floating point exceptionSami Kerola2019-05-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | As the title tells this change indeed fixes floating point exception, but post processing as value overwrite feels a wrong. Possibly something in input is making cpu set count to go wrong, but I could not get my head around what could it be. Anyway avoiding division by zero seems better than crashing so lets do this atleast for now.

* lscpu: rename macros and functionsKarel Zak2019-03-191-77/+77
| | | | | | | We need to differentiate between output about CPUs and another stuff (caches in future). Let's make it more obvious in code. Signed-off-by: Karel Zak <kzak@redhat.com>
* lscpu: report more usable cache sizesKarel Zak2019-03-191-2/+41
| | | | | | | | | | | | | | | | | The current version reports cache size as reported by /sys, it means real size of the one piece of the cache. This way provides minimal overview about all system as the cache is often shared between CPUs. It seems better to report all size of the caches in the summary output. It also does not make sense to report sizes per core (or socket) as CPU topology may be pretty complicated. The final solution (not implemented yet) will be to have --list-caches where we can report all details like all-size, item-size, per-core size, ways, type, etc. Addresses: https://github.com/karelzak/util-linux/issues/663 Signed-off-by: Karel Zak <kzak@redhat.com>

* | lscpu, chcpu: Avoid use of the old CPU macrosStanislav Brabec2018-05-101-4/+9

* Avoid crash in min/max caculation when cpu#0 being offlineDirk Mueller2018-03-171-6/+6
| | | | | | | | When cpu#0 is offline, atof(NULL) is called which causes a segfault or endless loop depending on implementation circumstances. So instead of implicitely assumping that the first cpu is always available, do the presence checks for all including the first one.
