From 9d92af621f193c1c889ac8b6fd8c987ccd8aae1f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 20 Jul 2007 21:39:45 +0200 Subject: [CELL] cell: add vicinity information on spus This patch adds affinity data to each spu instance. A doubly linked list is created, meant to connect the spus in the physical order they are placed in the BE. SPUs near to memory should be marked as having memory affinity. Adjustments of the fields acording to FW properties is done in separate patches, one for CPBW, one for Malta (patch for Malta under testing).
