menu "PS3 Platform Options" depends on PPC_PS3 config PS3_HTAB_SIZE depends on PPC_PS3 int "PS3 Platform pagetable size" range 18 20 default 20 help This option is only for experts who may have the desire to fine tune the pagetable size on their system. The value here is expressed as the log2 of the page table size. Valid values are 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively. If unsure, choose the default (20) with the confidence that your system will have optimal runtime performance. config PS3_DYNAMIC_DMA depends on PPC_PS3 && EXPERIMENTAL bool "PS3 Platform dynamic DMA page table management" default n help This option will enable kernel support to take advantage of the per device dynamic DMA page table management provided by the Cell processor's IO Controller. This support incurs some runtime overhead and also slightly increases kernel memory usage. The current implementation should be considered experimental. This support is mainly for Linux kernel development. If unsure, say N. endmenu
