Takashi Yamamoto 781749a46b [POWERPC] PS3: Add logical performance monitor driver support
Add PS3 logical performance monitor (lpm) device driver.

The PS3's LV1 hypervisor provides a Logical Performance Monitor that
abstracts the Cell processor's performance monitor features for use
by guest operating systems.

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.

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 && 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

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 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 system control. In
general, all users will say Y or M.
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, all 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_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.
