* lspcu: minor manpage improvementHeiko Carstens2016-08-031-2/+2
| | | | | | | | | | Always use the word "can" instead of "may" to be consistent with the descriptions of the other columns. Also print "lspcu" always with bold characters like everywhere else in the man page. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
* lscpu: add --physical optionHeiko Carstens2016-08-031-1/+11
| | | | | | | | | | | | | | | | | | With the --physical option lscpu will use the IDs that are reported by the kernel (e.g. core id for the CORE column) instead of calculating them on it's own. This has the advantage that it is possible to tell on which physical hardware CPUs a Linux instance runs. The logical IDs that lscpu generates on it own are based on comparing of CPU masks and may or may not be identical with the physical IDs. If the kernel was unable to retrieve an ID for a topology element then the corresponding sysfs file will normally contain "-1". In the extended and parsable output a dash "-" will be displayed for such cases. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
* lscpu: fix MMHZ column entry within man pageHeiko Carstens2016-06-241-3/+6
| | | | | | | | | | The indentation for the MMHZ column within the man page is wrong. Also there doesn't exist any column with the name MMHZ. The correct names would be MAXMHZ and MINMHZ. Therefore rename MMHZ to MAXMHZ and add the missong MINMHZ entry. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

* lscpu: Print physical cpu informationSukadev Bhattiprolu2015-12-021-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lscpu currently prints information for CPUs configured in the system. In case of KVM or other virtualized guest operating systems, this refers to the virtual system, and bears no relation to the physical topology of the system. It would be useful if lscpu could also display the physical topology info when available: $ ./lscpu Architecture: ppc64le Byte Order: Little Endian CPU(s): 16 On-line CPU(s) list: 0-15 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 16 NUMA node(s): 1 Model: IBM pSeries (emulated by qemu) Hypervisor vendor: KVM Virtualization type: para L1d cache: 64K L1i cache: 32K NUMA node0 CPU(s): 0-15 Physical sockets: 2 <<< New Physical chips: 4 <<< New Physical cores/chip: 4 <<< New For now, physical topology information is available on platforms that support the following RTAS (Real time abstraction service) call provided by librtas: rtas_get_sysparm(PROCESSOR_MODULE_INFO). Currently this call is available to the PowerVM (pHYP) guests on PowerPC. With a patch propoosed to PowerKVM, this RTAS call would also be available to PowerKVM guests.

| | | | | | | Passing the --all, --online or --offline options for the output summary doesn't make much sense. It should be limited to the two list output options. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

* lscpu: add --offline optionHeiko Carstens2011-09-271-3/+6
| | | | | | | | | | | | | | Implement "--offline" option which only prints offline cpus. As a side effect we can get rid of the internal "allcpus" flag, since if we want to print informations for online and offline cpus we simply set both flags. When reading sysfs attributes of cpus this is now done for all cpus, since e.g. the topology informations of the online cpus may influence the topology informations of the offline cpus. This mainly because online cpus may contain masks which include offline cpus while offline cpus have a missing topology directory. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

* lscpu: add online state to outputHeiko Carstens2011-09-091-1/+1
| | | | | | | | | | | | | | lscpu only prints lines for online CPUs. At least for the human readable list the offline CPUs are of interest as well. In order to distinguish between online and offline CPUs introduce the "Online" column. By default the human readable output now displays online and offline CPUs. The parsable output is not changed. It will print only lines for online CPUs as it used to do. [kzak@redhat.com: - minor changes] Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* lscpu: add configured state to outputHeiko Carstens2011-09-091-1/+1
| | | | | | | | | CPUs may be in a configured or deconfigured state depending if the CPU resource may be used by the guest. If a CPU is in configured state the guest may use it (i.e. set it online). It it is in deconfigured state it cannot use it before changing its state to configured. Display this CPU attribute as well. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
* lscpu: add human readable extended cpu table outputKarel Zak2011-09-091-8/+21
| | | | | | | | | | | | | | | | | Based on patch from Heiko Carstens <heiko.carstens@de.ibm.com>: lscpu currently only supports a parsable output which contains a row for each cpu and its attributes. This output contains only comas as separators and is hard to read for humans. Therefore add a new option "-e | --extended" which outputs the rows in a much more readable (and non-parsable) form. Just like for the -p option a list of columns can be specified that shall be included in the output. By default this option will print all columns that contain data.

| | | | | | | | | | | | | | | | | | | | | | | | chcpu can modify the logical state of CPUs. It can enable and disable CPUs, scan for new CPUs, change the CPU dispatching mode of the underlying hypervisor and request (configure) or give logical CPUs back (deconfigure) to the the underlying hypervisor. This is quite useful if you work a lot with virtual servers, since doing all the configuration stuff directly via sysfs becomes a pain. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running in different dispatching mode the virtual cpus may have different polarizations. E.g. in "vertical" mode cpus may have a polarization of "vertical:high" which means the virtual cpu has dedicated physical cpu assigned. Print this information in the parsable output. Note that this breaks the current rule that a) the parseable output contains only numbers b) these numbers are equal or increased in each line Since however this new item must be selected with the "list" argument this shouldn't be a problem.
