%description
|
|
qclib provides a C API for extraction of system information for Linux on z
|
|
Systems.
|
|
|
|
For instance, it will provide the number of CPUs
|
|
* on the machine (CEC, Central Electronic Complex) layer
|
|
* on the PR/SM (Processor Resource/Systems Manager) layer, i.e. visible to
|
|
LPARs
|
|
* in z/VM hosts, guests and CPU pools
|
|
* in KVM hosts and guests
|
|
This allows calculating the upper limit of CPU resources a highest level guest
|
|
can use.
|
|
|
|
E.g.: If an LPAR on a z13 provides 4 CPUs to a z/VM hypervisor, and the
|
|
hypervisor provides 8 virtual CPUs to a guest, qclib can be used to retrieve
|
|
all of these numbers, and it can be concluded that not more capacity than 4
|
|
CPUs can be used by the software running in the guest.
|
|
|
|
qclib uses various interfaces and provides this data through a common and
|
|
consistent API (Application Programming Interface), using information provided
|
|
by:
|
|
* STSI (Store System Information) instruction - for more details, refer to
|
|
the z/Architecture Principles of Operation (SA22-7832)
|
|
* STHYI (Store Hypervisor Information) instruction as provided by a z/VM
|
|
hypervisor - for more information, refer to z/VM: V6R3 CP Programming
|
|
Service (SC24-6179), chapter 'Store Hypervisor Information (STHYI)
|
|
Instruction'.
|
|
* hypfs file system - for more information, refer to 'Device Drivers,
|
|
Features, and Commands', chapter 'S/390 hypervisor file system'.
