1menu "PS3 Platform Options" 2 depends on PPC_PS3 3 4config PS3_ADVANCED 5 depends on PPC_PS3 6 bool "PS3 Advanced configuration options" 7 help 8 This gives you access to some advanced options for the PS3. The 9 defaults should be fine for most users, but these options may make 10 it possible to better control the kernel configuration if you know 11 what you are doing. 12 13 Note that the answer to this question won't directly affect the 14 kernel: saying N will just cause the configurator to skip all 15 the questions about these options. 16 17 Most users should say N to this question. 18 19config PS3_HTAB_SIZE 20 depends on PPC_PS3 21 int "PS3 Platform pagetable size" if PS3_ADVANCED 22 range 18 20 23 default 20 24 help 25 This option is only for experts who may have the desire to fine 26 tune the pagetable size on their system. The value here is 27 expressed as the log2 of the page table size. Valid values are 28 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively. 29 30 If unsure, choose the default (20) with the confidence that your 31 system will have optimal runtime performance. 32 33config PS3_DYNAMIC_DMA 34 depends on PPC_PS3 && EXPERIMENTAL 35 bool "PS3 Platform dynamic DMA page table management" 36 default n 37 help 38 This option will enable kernel support to take advantage of the 39 per device dynamic DMA page table management provided by the Cell 40 processor's IO Controller. This support incurs some runtime 41 overhead and also slightly increases kernel memory usage. The 42 current implementation should be considered experimental. 43 44 This support is mainly for Linux kernel development. If unsure, 45 say N. 46 47config PS3_USE_LPAR_ADDR 48 depends on PPC_PS3 && EXPERIMENTAL 49 bool "PS3 use lpar address space" 50 default y 51 help 52 This option is solely for experimentation by experts. Disables 53 translation of lpar addresses. SPE support currently won't work 54 without this set to y. 55 56 If you have any doubt, choose the default y. 57 58config PS3_VUART 59 depends on PPC_PS3 60 bool "PS3 Virtual UART support" if PS3_ADVANCED 61 default y 62 help 63 Include support for the PS3 Virtual UART. 64 65 This support is required for several system services 66 including the System Manager and AV Settings. In 67 general, all users will say Y. 68 69config PS3_PS3AV 70 tristate "PS3 AV settings driver" if PS3_ADVANCED 71 depends on PS3_VUART 72 default y 73 help 74 Include support for the PS3 AV Settings driver. 75 76 This support is required for graphics and sound. In 77 general, all users will say Y or M. 78 79config PS3_SYS_MANAGER 80 bool "PS3 System Manager driver" if PS3_ADVANCED 81 depends on PS3_VUART 82 default y 83 help 84 Include support for the PS3 System Manager. 85 86 This support is required for system control. In 87 general, all users will say Y. 88 89endmenu 90
