Use 64K pages to map SPE local store
configname: CONFIG_SPU_FS_64K_LS
Linux Kernel Configuration
└─>Cell Broadband Engine options
└─>Use 64K pages to map SPE local store
In linux kernel since version 2.6.22 (release Date: 2007-07-08)
This option causes SPE local stores to be mapped in process
address spaces using 64K pages while the rest of the kernel
uses 4K pages. This can improve performances of applications
using multiple SPEs by lowering the TLB pressure on them.
