| 6 | int "PS3 Platform pagetable size" | |
| 7 | range 18 20 | |
| 8 | default 20 | |
| 9 | help | |
| 10 | This option is only for experts who may have the desire to fine | |
| 11 | tune the pagetable size on their system. 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. | |

| 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. | |

| 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. | |

| 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. | |
