[PATCH] powerpc: Add cputable entry for POWER6

2006-04-29T00:56:58+00:00

Add a cputable entry for the POWER6 processor.

The SIHV and SIPR bits in the mmcra have moved in POWER6, so disable
support for that until oprofile is fixed.

Also tell firmware that we know about POWER6.

[PATCH] powerpc: Expose SMT and L1 icache snoop userland features

2006-03-03T11:00:23+00:00

This patch makes userland aware of the icache snoop capability of the
POWER5 (and possibly others in the future) and of SMT capabilities.

[PATCH] powerpc: oprofile cpu type names clash with other code

2006-01-14T00:12:16+00:00

In 2.6.15-git6 a change was commited in the oprofile support in
the powerpc architecture.  It introduced the powerpc_oprofile_type
which contains the define G4.  This causes a name clash with the
existing wacom usb tablet driver.

      CC [M]  drivers/usb/input/wacom.o
    drivers/usb/input/wacom.c:98: error: conflicting types for `G4'
    include/asm/cputable.h:37: error: previous declaration of `G4'
      CC [M]  drivers/usb/mon/mon_text.o
    make[3]: *** [drivers/usb/input/wacom.o] Error 1
    make[2]: *** [drivers/usb/input] Error 2

The elements of an enum declared in global scope are effectivly
global identifiers themselves.  As such we need to ensure the names
are unique.  This patch updates the later oprofile support to use
unique names.

powerpc: Provide a suitable AT_PLATFORM value

2006-01-13T23:11:39+00:00

The glibc folks want to use AT_PLATFORM to select between possible
alternative versions of shared libraries.  This commit makes the kernel
supply an AT_PLATFORM string that indicates what class of processor
we are running on.  Processors with the same set of user-level
instructions and roughly the same instruction scheduling characteristics
are given the same AT_PLATFORM value; for example, 821, 823 and 860
are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455
are all called "ppc7450".

The intention is that the AT_PLATFORM values match the values that
gcc accepts for the -mcpu= option.  For values which are numeric
(e.g. -mcpu=750), "ppc" has been prepended.

This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets
it for the 440 family and the Freescale 85xx family.

[PATCH] ppc64: POWER5+ oprofile support

2006-01-09T05:03:30+00:00

POWER5+ adds new PMU groups and as such needs to be treated differently
by oprofile userspace. Change it to report itself as power5+.

[PATCH] ppc64: Fix oprofile when compiled as a module

2006-01-09T05:02:52+00:00

My recent changes to oprofile broke it when built as a module. Fix it by
using an enum instead of a function pointer. This way we still retain
the oprofile configuration in the cputable.

[PATCH] cell: enable pause(0) in cpu_idle

2006-01-09T04:44:32+00:00

This patch enables support for pause(0) power management state
for the Cell Broadband Processor, which is import for power efficient
operation. The pervasive infrastructure will in the future enable
us to introduce more functionality specific to the Cell's
pervasive unit.

[PATCH] powerpc: G4+ oprofile support

2006-01-09T04:06:03+00:00

This patch adds oprofile support for the 7450 and all its multitudinous
derivatives.

* Added 7450 (and derivatives) support for oprofile
* Changed e500 cputable to have oprofile model and cpu_type fields
* Added support for classic 32-bit performance monitor interrupt
* Cleaned up common powerpc oprofile code to be as common as possible
* Cleaned up oprofile_impl.h to reflect 32 bit classic code
* Added 32-bit MMCRx bitfield definitions and SPR numbers
