[POWERPC] Remove CPU_FTR_NEED_COHERENT for 7448.

2007-05-17T11:10:15+00:00

Remove CPU_FTR_NEED_COHERENT for MPC7448 (and single-core MPC86xx).
This prevents needlessly setting M=1 when not SMP.

[POWERPC] pasemi: PA6T oprofile support

2007-04-24T11:31:51+00:00

Oprofile support for PA6T, kernel side.

Also rename the PA6T_SPRN.* defines to SPRN_PA6T.*.

[POWERPC] Fix PowerPC 750CL and 750GX CPU features

2007-04-24T11:31:47+00:00

PowerPC 750CL has high BATs.  The patch below adds a CPU_FTRS_750CL that
includes that.  Without it, the original firmware mappings in the high BATs
aren't cleared which continue to override the linux translations.

It also adds CPU_FTR_COMMON to CPU_FTRS_750GX for completeness.

[POWERPC] Add PMC type to cputable

2007-02-07T03:03:19+00:00

Add cputable entries for which type of PMC implementation the processor
has.

I've only filled in the current 64-bit processors, the unfilled default
value will have same behaviour as before so it can be done over time
as needed.

Also tidy up the dummy_perf implementation a bit, aggregating it into
one function with ifdefs instead of several.

[POWERPC] Add DSCR SPR to sysfs

2006-12-09T00:39:05+00:00

POWER6 adds a new SPR, the data stream control register (DSCR). It can
be used to adjust how agressive the prefetch mechanisms are.

Its possible we may want to context switch this, but for now just export
it to userspace via sysfs so we can adjust it.

[POWERPC] Add support for FP emulation for the e300c2 core

2006-12-08T08:43:30+00:00

The e300c2 has no FPU.  Its MSR[FP] is grounded to zero.  If an attempt
is made to execute a floating point instruction (including floating-point
load, store, or move instructions), the e300c2 takes a floating-point
unavailable interrupt.

This patch adds support for FP emulation on the e300c2 by declaring a
new CPU_FTR_FP_TAKES_FPUNAVAIL, where FP unavail interrupts are
intercepted and redirected to the ProgramCheck exception path for
correct emulation handling.

(If we run out of CPU_FTR bits we could look to reclaim this bit by adding
support to test the cpu_user_features for PPC_FEATURE_HAS_FPU instead)

It adds a nop to the exception path for 32-bit processors with a FPU.

[POWERPC] Make 64-bit cpu features defined on 32-bit

2006-12-04T09:40:34+00:00

It saves #ifdef'ing in callers if we at least define the 64-bit cpu
features for 32-bit also.
