Subject: [patch 3/4] intr_remap: Allocate intr-remapping table using numa locality info
Date: Thu, 01 Oct 2009 16:06:18 -0700 [thread overview]
Message-ID: <20091001230744.135836864@sbs-t61.sc.intel.com> (raw)
In-Reply-To: <20091001230743.949931468@sbs-t61.sc.intel.com>
[-- Attachment #1: intr_remap_use_affinity_info.patch --]
[-- Type: text/plain, Size: 895 bytes --]
Allocate intr-remapping table using numa locality info. On platforms
having remapping hardware units span different nodes, this enables
optimized intr-remapping table entry access by remapping hardware.
