The value here is 12 expressed as the log2 of the page table size. Valid values are 13 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively. 14 15 If unsure, choose the default (20) with the confidence that your 16 system will have optimal runtime performance. 17 18config PS3_DYNAMIC_DMA 19 depends on PPC_PS3 && EXPERIMENTAL 20 bool "PS3 Platform dynamic DMA page table management" 21 default n 22 help 23 This option will enable kernel support to take advantage of the 24 per device dynamic DMA page table management provided by the Cell 25 processor's IO Controller. This support incurs some runtime 26 overhead and also slightly increases kernel memory usage. The 27 current implementation should be considered experimental. 28 29 This support is mainly for Linux kernel development. If unsure, 30 say N. 31 32config PS3_USE_LPAR_ADDR 33 depends on PPC_PS3 && EXPERIMENTAL 34 bool "PS3 use lpar address space" 35 default y 36 help 37 This option is solely for experimentation by experts. Disables 38 translation of lpar addresses. SPE support currently won't work 39 without this set to y. 40 41 If you have any doubt, choose the default y. 42 43config PS3_VUART 44 depends on PPC_PS3 45 bool "PS3 Virtual UART support" 46 default y 47 help 48 Include support for the PS3 Virtual UART. 49 50 This support is required for several system services 51 including the System Manager and AV Settings. In 52 general, all users will say Y. 53 54config PS3_PS3AV 55 tristate "PS3 AV settings driver" 56 depends on PPC_PS3 57 select PS3_VUART 58 default y 59 help 60 Include support for the PS3 AV Settings driver. 61 62 This support is required for graphics and sound. In 63 general, all users will say Y or M. 64 65endmenu 66
