This patch adds new dcr_map/dcr_read/dcr_write accessors for DCRs that can be used by drivers to transparently address either native DCRs or memory mapped DCRs. The implementation for memory mapped DCRs is done after the binding being currently worked on for SLOF and the Axon chipset. This patch enables it for the cell native platform Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

There are four types of PowerPC chips supported. The more common
|
|
types (601, 603, 604, 740, 750, 7400), the older Freescale
|
|
(formerly Motorola) embedded versions (821, 823, 850, 855, 860,
|
|
52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and
|
|
the Book E embedded processors from IBM (44x) and Freescale (85xx).
|
|
For support for 64-bit processors, set ARCH=powerpc.
|
|
Unless you are building a kernel for one of the embedded processor
|
|
systems, choose 6xx.
|

Also note that because the 52xx, 82xx, & 83xx family have a 603e

core, specific support for that chipset is asked later on.

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)"

|
|
---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.
|

bool "Average high and low temp"

---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.

bool "Math emulation"

depends on 4xx || 8xx || E200 || E500
|
|
---help---
|
|
Some PowerPC chips designed for embedded applications do not have
|
|
a floating-point unit and therefore do not implement the
|
|
floating-point instructions in the PowerPC instruction set. If you
|
|
say Y here, the kernel will include code to emulate a floating-point
|
|
unit, which will allow programs that use floating-point
|
|
instructions to run.
|
|
|
|
If you have an Apple machine or an IBM RS/6000 or pSeries machine,
|
|
or any machine with a 6xx, 7xx or 7xxx series processor, say N
|

will increase the size of the kernel.

config KEXEC
|

bool "kexec system call (EXPERIMENTAL)"
|
|
depends on EXPERIMENTAL
|
|
help
|
|
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 independent of the system firmware. And like a reboot
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
The name comes from the similarity 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.
|
|
|
|
In the GameCube implementation, kexec allows you to load and
|
|
run DOL files, including kernel and homebrew DOLs.

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.

Linux currently supports several different kinds of PowerPC-based
|
|
machines: Apple Power Macintoshes and clones (such as the Motorola
|
|
Starmax series), PReP (PowerPC Reference Platform) machines (such
|
|
as the Motorola PowerStacks, Motorola cPCI/VME embedded systems,
|
|
and some IBM RS/6000 systems), CHRP (Common Hardware Reference
|
|
Platform) machines (including all of the recent IBM RS/6000 and
|
|
pSeries machines), and several embedded PowerPC systems containing
|
|
4xx, 6xx, 7xx, 8xx, 74xx, and 82xx processors. Currently, the
|
|
default option is to build a kernel which works on PReP.

Note that support for Apple and CHRP machines is now only available

with ARCH=powerpc, and has been removed from this menu. If you

This option supports the 2232 7-port serial card shipped with the
|
|
Amiga 2000 and other Zorro-bus machines, dating from 1989. At
|
|
a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
|
|
each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
|
|
ports were connected with 8 pin DIN connectors on the card bracket,
|
|
for which 8 pin to DB25 adapters were supplied. The card also had
|
|
jumpers internally to toggle various pinning configurations.
|
|
|

This driver can be built as a module; but then "generic_serial"
|
|
will also be built as a module. This has to be loaded before

the process as file descriptors supporting the read/write

syscalls, it's possible to isolate those applications in

their own address space using seccomp. Once seccomp is
