Subject: [Patch 0/2] Optimize CPU vector allocation for NUMA systems
Date: Mon, 4 May 2015 10:47:39 +0800 [thread overview]
Message-ID: <1430707662-28598-1-git-send-email-jiang.liu@linux.intel.com> (raw)
Hi all,
This is a small patch set based on tip/x86/apic.
This first patch is a bugfix for tip/x86/apic. And the second patch
is an enhancement to optimize CPU vector allocation on NUMA systems.
It introduces a mechanism to allocate CPU vectors from device local
NUMA node and a kernel parameter to enable/disable the optimization.
Thanks!
Gerry
