- menu "PS3 Platform Options"
- depends on PPC_PS3
- config PS3_HTAB_SIZE
- depends on PPC_PS3
- int "PS3 Platform pagetable size"
- range 18 20
- default 20
- help
- This option is only for experts who may have the desire to fine
- tune the pagetable size on their system. The value here is
- expressed as the log2 of the page table size. Valid values are
- 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
- If unsure, choose the default (20) with the confidence that your
- system will have optimal runtime performance.
- config PS3_DYNAMIC_DMA
- depends on PPC_PS3 && EXPERIMENTAL
- bool "PS3 Platform dynamic DMA page table management"
- default n
- help
- This option will enable kernel support to take advantage of the
- per device dynamic DMA page table management provided by the Cell
- processor's IO Controller. This support incurs some runtime
- overhead and also slightly increases kernel memory usage. The
- current implementation should be considered experimental.
- This support is mainly for Linux kernel development. If unsure,
- say N.
- config PS3_USE_LPAR_ADDR
- depends on PPC_PS3 && EXPERIMENTAL
- bool "PS3 use lpar address space"
- default y
- help
- This option is solely for experimentation by experts. Disables
- translation of lpar addresses. SPE support currently won't work
- without this set to y.
- If you have any doubt, choose the default y.
- config PS3_VUART
- depends on PPC_PS3
- bool "PS3 Virtual UART support"
- default y
- help
- Include support for the PS3 Virtual UART.
- This support is required for several system services
- including the System Manager and AV Settings. In
- general, all users will say Y.
