6 int "PS3 Platform pagetable size"
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.
15 If unsure, choose the default (20) with the confidence that your
16 system will have optimal runtime performance.
18 config PS3_DYNAMIC_DMA
19 depends on PPC_PS3 && EXPERIMENTAL
20 bool "PS3 Platform dynamic DMA page table management"
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.
29 This support is mainly for Linux kernel development. If unsure,
32 config PS3_USE_LPAR_ADDR
33 depends on PPC_PS3 && EXPERIMENTAL
34 bool "PS3 use lpar address space"
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.
41 If you have any doubt, choose the default y.
45 bool "PS3 Virtual UART support"
48 Include support for the PS3 Virtual UART.
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.
