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

|

types (601, 603, 604, 740, 750, 7400), the Motorola embedded
|
|
|
|
|
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).

This option is the catch-all for 6xx types, including some of the
|
|
|
|
|
embedded versions. Unless there is see an option for the specific
|
|
|
|
|
chip family you are using, you want this option.
|
|
|
|
|
|
|
|
|
|
You do not want this if you are building a kernel for a 64 bit
|
|
|
|
|
IBM RS/6000 or an Apple G5, choose 6xx.

powerpc: Implement accurate task and CPU time accounting
This implements accurate task and cpu time accounting for 64-bit
powerpc kernels. Instead of accounting a whole jiffy of time to a
task on a timer interrupt because that task happened to be running at
the time, we now account time in units of timebase ticks according to
the actual time spent by the task in user mode and kernel mode. We
also count the time spent processing hardware and software interrupts
accurately. This is conditional on CONFIG_VIRT_CPU_ACCOUNTING. If
that is not set, we do tick-based approximate accounting as before.
To get this accurate information, we read either the PURR (processor
utilization of resources register) on POWER5 machines, or the timebase
on other machines on
* each entry to the kernel from usermode
* each exit to usermode
* transitions between process context, hard irq context and soft irq
context in kernel mode
* context switches.
On POWER5 systems with shared-processor logical partitioning we also
read both the PURR and the timebase at each timer interrupt and
context switch in order to determine how much time has been taken by
the hypervisor to run other partitions ("steal" time). Unfortunately,
since we need values of the PURR on both threads at the same time to
accurately calculate the steal time, and since we can only calculate
steal time on a per-core basis, the apportioning of the steal time
between idle time (time which we ceded to the hypervisor in the idle
loop) and actual stolen time is somewhat approximate at the moment.
This is all based quite heavily on what s390 does, and it uses the
generic interfaces that were added by the s390 developers,
i.e. account_system_time(), account_user_time(), etc.
This patch doesn't add any new interfaces between the kernel and
userspace, and doesn't change the units in which time is reported to
userspace by things such as /proc/stat, /proc/<pid>/stat, getrusage(),
times(), etc. Internally the various task and cpu times are stored in
timebase units, but they are converted to USER_HZ units (1/100th of a
second) when reported to userspace. Some precision is therefore lost
but there should not be any accumulating error, since the internal
accumulation is at full precision.

[POWERPC] Add QUICC Engine (QE) infrastructure
Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.
Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:
"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support. Qe_lib is used by
QE device drivers such as ucc_geth driver.
This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.
v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.
v3: Address comments from Kumar; Update definition of several
device tree nodes; Copyright style change."
In addition, the following changes have been made:
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues
o marked ioregs as __be32/__be16
o removed platform_device code and redundant get_qe_base()
o removed redundant comments
o added cpu_relax() to qe_reset
o uncasted all get_property() assignments
o eliminated unneeded casts
o eliminated immrbar_phys_to_virt (not used)

[POWERPC] Allow hooking of PCI MMIO & PIO accessors on 64 bits
This patch reworks the way iSeries hooks on PCI IO operations (both MMIO
and PIO) and provides a generic way for other platforms to do so (we
have need to do that for various other platforms).
While reworking the IO ops, I ended up doing some spring cleaning in
io.h and eeh.h which I might want to split into 2 or 3 patches (among
others, eeh.h had a lot of useless stuff in it).
A side effect is that EEH for PIO should work now (it used to pass IO
ports down to the eeh address check functions which is bogus).
Also, new are MMIO "repeat" ops, which other archs like ARM already had,
and that we have too now: readsb, readsw, readsl, writesb, writesw,
writesl.
In the long run, I might also make EEH use the hooks instead
of wrapping at the toplevel, which would make things even cleaner and
relegate EEH completely in platforms/iseries, but we have to measure the
performance impact there (though it's really only on MMIO reads)
Since I also need to hook on ioremap, I shuffled the functions a bit
there. I introduced ioremap_flags() to use by drivers who want to pass
explicit flags to ioremap (and it can be hooked). The old __ioremap() is
still there as a low level and cannot be hooked, thus drivers who use it
should migrate unless they know they want the low level version.
The patch "arch provides generic iomap missing accessors" (should be
number 4 in this series) is a pre-requisite to provide full iomap
API support with this patch.

[POWERPC] Allow hooking of PCI MMIO & PIO accessors on 64 bits
This patch reworks the way iSeries hooks on PCI IO operations (both MMIO
and PIO) and provides a generic way for other platforms to do so (we
have need to do that for various other platforms).
While reworking the IO ops, I ended up doing some spring cleaning in
io.h and eeh.h which I might want to split into 2 or 3 patches (among
others, eeh.h had a lot of useless stuff in it).
A side effect is that EEH for PIO should work now (it used to pass IO
ports down to the eeh address check functions which is bogus).
Also, new are MMIO "repeat" ops, which other archs like ARM already had,
and that we have too now: readsb, readsw, readsl, writesb, writesw,
writesl.
In the long run, I might also make EEH use the hooks instead
of wrapping at the toplevel, which would make things even cleaner and
relegate EEH completely in platforms/iseries, but we have to measure the
performance impact there (though it's really only on MMIO reads)
Since I also need to hook on ioremap, I shuffled the functions a bit
there. I introduced ioremap_flags() to use by drivers who want to pass
explicit flags to ioremap (and it can be hooked). The old __ioremap() is
still there as a low level and cannot be hooked, thus drivers who use it
should migrate unless they know they want the low level version.
The patch "arch provides generic iomap missing accessors" (should be
number 4 in this series) is a pre-requisite to provide full iomap
API support with this patch.

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
|
2006-03-27 16:15:26 +08:00
|
|
|
and in many cases, does not work at all, so don't assume the cpu
|
2005-09-26 14:04:21 +08:00

temp is actually what /proc/cpuinfo says it is.

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.
|
|
|
|
|

debugging, leave this option off.

The TAU hardware can compare the temperature to an 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,

kexec is a system call that implements the ability to shutdown your
|
|
|
|
|
current kernel, and to start another kernel. It is like a reboot
|
2006-06-29 13:32:47 +08:00
|
|
|
but it is independent of the system firmware. And like a reboot
|
2005-09-26 14:04:21 +08:00
|
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
|
|
2006-06-29 13:32:47 +08:00
|
|
|
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.

Build a kernel suitable for use as a kdump capture kernel.

The kernel will be linked at a different address than normal, and
|
|
|

so can only be used for Kdump.

[POWERPC] Add QUICC Engine (QE) infrastructure
Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.
Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:
"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support. Qe_lib is used by
QE device drivers such as ucc_geth driver.
This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.
v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.
v3: Address comments from Kumar; Update definition of several
device tree nodes; Copyright style change."
In addition, the following changes have been made:
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues
o marked ioregs as __be32/__be16
o removed platform_device code and redundant get_qe_base()
o removed redundant comments
o added cpu_relax() to qe_reset
o uncasted all get_property() assignments
o eliminated unneeded casts
o eliminated immrbar_phys_to_virt (not used)

Kprobes allows you to trap at almost any kernel address and
|
|
|
|
|
execute a callback function. register_kprobe() establishes
|
|
|
|
|
a probepoint and specifies the callback. Kprobes is useful
|
|
|
|
|
for kernel debugging, non-intrusive instrumentation and testing.
|
|

|
|
If in doubt, say "N".
