* lscpu: fix floating point exceptionSami Kerola2019-05-181-0/+76
| | | | | | | | | | | | | 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: remove extra space from field key nameSami Kerola2019-05-161-37/+37
| | | | | | | | | | | | | | | | | | | The extra space was more obvious in json output. But as the expected test output displays also the standard output can be effected by this change. $ lscpu --json | jq '.lscpu | .[].field' | grep ': ' "L1d cache: " "L1i cache: " "L2 cache: " "L3 cache: " "Vulnerability L1tf: " "Vulnerability Mds: " "Vulnerability Meltdown: " "Vulnerability Spec store bypass: " "Vulnerability Spectre v1: " "Vulnerability Spectre v2: " Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* lscpu: update s390-lpar-drawer testcaseHeiko Carstens2016-06-241-2/+1Star
| | | | | | | | | | | | | | | | I noticed that the "cpu" line within /proc/cpuinfo has a different meaning on powerpc and sparc than on s390. On s390 it represents the cpu number while on powerpc and sparc it represent the model name. Given that the s390 kernel patch which adds the "cpu" line to /proc/cpuinfo hasn't been merged into the kernel yet, I changed that line to "cpu number" to avoid the unnecessary conflict. Therefore this patch updates the testcase, which mainly changes the contents of /proc/cpuinfo. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
* lscpu: show additional caches (s390)Heiko Carstens2016-06-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | The Linux kernel exposes the cache topology via sysfs. However on virtualized machines like s390 the cache topology contains only cpu private caches. For shared caches it is not known which cpus share them. The hypervisor would have to update this information whenever a virtual cpu would be scheduled on a different physical cpu and make the guest aware of that change. Given that there is hardly any benefit, if it all, this isn't done. However it is still of interest to know about the non-private caches. Therefore this information is available via /proc/cpuinfo at least on s390. This patch adds additional lines to the summary output for all shared caches for which information can be found in /proc/cpuinfo, since we know these aren't exposed via sysfs.

* lscpu: show static and dynamic MHz (s390)Heiko Carstens2016-06-241-0/+2
| | | | | | | | | | | | | | | | s390 machines provide static and dynamic cpu mhz information via /proc/cpuinfo. The static cpu mhz is the normal cpu frequency a cpu is supposed to run with. The dynamic cpu mhz is the actual frequency a cpu is running with. This is usually the same as the static cpu mhz. Note that this values are different to the min/max mhz values available on other architecutes. The min/max values are unknown. This patch adds two new fields to the summary output which display these two values. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
