The value here is 12f58a9d17SGeoff Levand expressed as the log2 of the page table size. Valid values are 13f58a9d17SGeoff Levand 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively. 14f58a9d17SGeoff Levand 15f58a9d17SGeoff Levand If unsure, choose the default (20) with the confidence that your 16f58a9d17SGeoff Levand system will have optimal runtime performance. 17f58a9d17SGeoff Levand 18f58a9d17SGeoff Levandconfig PS3_DYNAMIC_DMA 19f58a9d17SGeoff Levand depends on PPC_PS3 && EXPERIMENTAL 20f58a9d17SGeoff Levand bool "PS3 Platform dynamic DMA page table management" 21f58a9d17SGeoff Levand default n 22f58a9d17SGeoff Levand help 23f58a9d17SGeoff Levand This option will enable kernel support to take advantage of the 24f58a9d17SGeoff Levand per device dynamic DMA page table management provided by the Cell 25f58a9d17SGeoff Levand processor's IO Controller. This support incurs some runtime 26f58a9d17SGeoff Levand overhead and also slightly increases kernel memory usage. The 27f58a9d17SGeoff Levand current implementation should be considered experimental. 28f58a9d17SGeoff Levand 29f58a9d17SGeoff Levand This support is mainly for Linux kernel development.
