Enables NUMA topology reporting on PowerPC architecture
|
|
from the libvirt driver in Nova but with a caveat as mentioned below.
|
|
NUMA cell affinity and dedicated cpu pinning
|
|
code assumes that the host operating system is exposed to threads.
|
|
PowerPC based hosts use core based scheduling for processes.
|
|
Due to this, the cores on the PowerPC architecture are treated as
|
|
threads. Since cores are always less than or equal
|
|
to the threads on a system, this leads to non-optimal resource usage
|
|
while pinning. This feature is supported from libvirt version 1.2.19
|
|
for PowerPC.
