From 8545129540a5862b22aad03badb2a9f93bf29117 Mon Sep 17 00:00:00 2001 From: Bob Cochran Date: Mon, 3 Nov 2014 22:45:35 -0500 Subject: [meta-fsl-ppc][PATCH] linux-qoriq: Change defconfig for T1040 to match number of CPUS Having a number higher than necessary for NR_CPUS wastes memory by instantiating unnecessary structures in RAM. An example is in the DPAA where DPAA_ETH_TX_QUEUES is defined based on NR_CPUS and used to create dozens of extra qman_fq structures. Using the prior value of 24, which was left over from the T4240 created an additonal 60 frame queue structures alone. This has been tested on t1040rdb-64b. .
