Arnd Bergmann 67207b9664 [PATCH] spufs: The SPU file system, base 
This is the current version of the spu file system, used
for driving SPEs on the Cell Broadband Engine.

This release is almost identical to the version for the
2.6.14 kernel posted earlier, which is available as part
of the Cell BE Linux distribution from
http://www.bsc.es/projects/deepcomputing/linuxoncell/.

The first patch provides all the interfaces for running
spu application, but does not have any support for
debugging SPU tasks or for scheduling. Both these
functionalities are added in the subsequent patches.

See Documentation/filesystems/spufs.txt on how to use
spufs.

There are four families of PowerPC chips supported. The more common

versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
embedded versions (403 and 405) and the high end 64 bit Power
processors (POWER 3, POWER4, and IBM PPC970 also known as G5).
Unless you are building a kernel for one of the embedded processor
systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
Note that the kernel runs in 32-bit mode even on 64-bit chips.

This option enables kernel support for the Altivec extensions to the
PowerPC processor. The kernel currently supports saving and restoring
altivec registers, and turning on the 'altivec enable' bit so user
processes can execute altivec instructions.
This option is only usefully if you have a processor that supports
altivec (G4, otherwise known as 74xx series), but does not have
any affect on a non-altivec cpu (it does, however add code to the
kernel).
If in doubt, say Y here.

This option enables kernel support for the Signal Processing

'spe enable' bit so user processes can execute SPE instructions.
This option is only useful if you have a processor that supports

than one CPU, say Y. Note that the kernel does not currently
support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
since they have inadequate hardware support for multiprocessor
operation.
If you say N here, the kernel will run on single and multiprocessor
machines, but will use only one CPU of a multiprocessor machine. If
you say Y here, the kernel will run on single-processor machines.
On a single-processor machine, the kernel will run faster if you say
N here.

bool "Workarounds for PPC601 bugs"
depends on 6xx && (PPC_PREP || PPC_PMAC)
help
Some versions of the PPC601 (the first PowerPC chip) have bugs which
mean that extra synchronization instructions are required near
certain instructions, typically those that make major changes to the
CPU state. These extra instructions reduce performance slightly.
If you say N here, these extra instructions will not be included,
resulting in a kernel which will run faster but may not run at all
on some systems with the PPC601 chip.
If in doubt, say Y here.
config TAU
bool "Thermal Management Support"
depends on 6xx
help
G3 and G4 processors have an on-chip temperature sensor called the
'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
temperature within 2-4 degrees Celsius. This option shows the current
on-die temperature in /proc/cpuinfo if the cpu supports it.
Unfortunately, on some chip revisions, this sensor is very inaccurate
and in some cases, does not work at all, so don't assume the cpu
temp is actually what /proc/cpuinfo says it is.
config TAU_INT
bool "Interrupt driven TAU driver (DANGEROUS)"
depends on TAU
---help---
The TAU supports an interrupt driven mode which causes an interrupt
whenever the temperature goes out of range. This is the fastest way
to get notified the temp has exceeded a range. With this option off,
a timer is used to re-check the temperature periodically.
However, on some cpus it appears that the TAU interrupt hardware
is buggy and can cause a situation which would lead unexplained hard
lockups.
Unless you are extending the TAU driver, or enjoy kernel/hardware
debugging, leave this option off.
config TAU_AVERAGE
bool "Average high and low temp"
depends on TAU
---help---
The TAU hardware can compare the temperature to an upper and lower
bound. The default behavior is to show both the upper and lower
bound in /proc/cpuinfo. If the range is large, the temperature is
either changing a lot, or the TAU hardware is broken (likely on some
G4's). If the range is small (around 4 degrees), the temperature is
relatively stable. If you say Y here, a single temperature value,
halfway between the upper and lower bounds, will be reported in
/proc/cpuinfo.
If in doubt, say N here.

Some PowerPC chips designed for embedded applications do not have

help
Cause IO segments sent to a device for DMA to be merged virtually
by the IOMMU when they happen to have been allocated contiguously.
This doesn't add pressure to the IOMMU allocator. However, some

kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
but it is indepedent of the system firmware. And like a reboot
you can start any kernel with it, not just Linux.
The name comes from the similiarity to the exec system call.
It is an ongoing process to be certain the hardware in a machine
is properly shutdown, so do not be surprised if this code does not
initially work for you. It may help to enable device hotplugging
support. As of this writing the exact hardware interface is
strongly in flux, so no good recommendation can be made.

their own address space using seccomp. Once seccomp is
