config PPC_PS3
bool "Sony PS3"
depends on PPC64 && PPC_BOOK3S && CPU_BIG_ENDIAN
select PPC_CELL
select USB_OHCI_LITTLE_ENDIAN
select USB_OHCI_BIG_ENDIAN_MMIO
select USB_EHCI_BIG_ENDIAN_MMIO
select HAVE_PCI
help
This option enables support for the Sony PS3 game console
and other platforms using the PS3 hypervisor. Enabling this
option will allow building otheros.bld, a kernel image suitable
for programming into flash memory, and vmlinux, a kernel image
suitable for loading via kexec.
menu "PS3 Platform Options"
depends on PPC_PS3
config PS3_ADVANCED
depends on PPC_PS3
bool "PS3 Advanced configuration options"
help
This gives you access to some advanced options for the PS3. The
defaults should be fine for most users, but these options may make
it possible to better control the kernel configuration if you know
what you are doing.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about these options.
Most users should say N to this question.
config PS3_HTAB_SIZE
depends on PPC_PS3
int "PS3 Platform pagetable size" if PS3_ADVANCED
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
bool "PS3 Platform dynamic DMA page table management"
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_VUART
depends on PPC_PS3
tristate
config PS3_PS3AV
depends on PPC_PS3
tristate "PS3 AV settings driver" if PS3_ADVANCED
select PS3_VUART
default y
help
Include support for the PS3 AV Settings driver.
This support is required for PS3 graphics and sound. In
general, all users will say Y or M.
config PS3_SYS_MANAGER
depends on PPC_PS3
tristate "PS3 System Manager driver" if PS3_ADVANCED
select PS3_VUART
default y
help
Include support for the PS3 System Manager.
This support is required for PS3 system control. In
general, all users will say Y or M.
config PS3_REPOSITORY_WRITE
bool "PS3 Repository write support" if PS3_ADVANCED
depends on PPC_PS3
help
Enables support for writing to the PS3 System Repository.
This support is intended for bootloaders that need to store data
in the repository for later boot stages.
If in doubt, say N here and reduce the size of the kernel by a
small amount.
config PS3_STORAGE
depends on PPC_PS3
tristate
config PS3_DISK
tristate "PS3 Disk Storage Driver"
depends on PPC_PS3 && BLOCK
select PS3_STORAGE
help
Include support for the PS3 Disk Storage.
This support is required to access the PS3 hard disk.
In general, all users will say Y or M.
config PS3_ROM
tristate "PS3 BD/DVD/CD-ROM Storage Driver"
depends on PPC_PS3 && SCSI
select PS3_STORAGE
help
Include support for the PS3 ROM Storage.
This support is required to access the PS3 BD/DVD/CD-ROM drive.
In general, all users will say Y or M.
Also make sure to say Y or M to "SCSI CDROM support" later.
config PS3_FLASH
tristate "PS3 FLASH ROM Storage Driver"
depends on PPC_PS3
select PS3_STORAGE
help
Include support for the PS3 FLASH ROM Storage.
This support is required to access the PS3 FLASH ROM, which
contains the boot loader and some boot options.
In general, PS3 OtherOS users will say Y or M.
As this driver needs a fixed buffer of 256 KiB of memory, it can
be disabled on the kernel command line using "ps3flash=off", to
not allocate this fixed buffer.
config PS3_VRAM
tristate "PS3 Video RAM Storage Driver"
depends on FB_PS3=y && BLOCK && m
help
This driver allows you to use excess PS3 video RAM as volatile
storage or system swap.
config PS3_LPM
tristate "PS3 Logical Performance Monitor support"
depends on PPC_PS3
help
Include support for the PS3 Logical Performance Monitor.
This support is required to use the logical performance monitor
of the PS3's LV1 hypervisor.
If you intend to use the advanced performance monitoring and
profiling support of the Cell processor with programs like
oprofile and perfmon2, then say Y or M, otherwise say N.
config PS3GELIC_UDBG
bool "PS3 udbg output via UDP broadcasts on Ethernet"
depends on PPC_PS3
help
Enables udbg early debugging output by sending broadcast UDP
via the Ethernet port (UDP port number 18194).
This driver uses a trivial implementation and is independent
from the main PS3 gelic network driver.
If in doubt, say N here.
