4 | Subject: [meta-fsl-ppc][PATCH] linux-qoriq: Change defconfig for T1040 to | ||
5 | match number of CPUS | ||
6 | |||
7 | Having a number higher than necessary for NR_CPUS wastes memory by | ||
8 | instantiating unnecessary structures in RAM. An example is in the DPAA where | ||
9 | DPAA_ETH_TX_QUEUES is defined based on NR_CPUS and used to create | ||
10 | dozens of extra qman_fq structures. Using the prior value of 24, which was | ||
11 | left over from the T4240 created an additonal 60 frame queue structures alone. | ||
12 | |||
13 | This has been tested on t1040rdb-64b. . | ||
