2007-02-07[POWERPC] Oprofile cleanupOlof Johansson
Clean up the ctr_read/write a bit. It's currently defined in the include but only used in one C file each. The only exception is the classic version, so keep that in the include and define in the C file as appropriate.

2006-11-01[POWERPC] Fix oprofile support for e500 in arch/powerpcAndy Fleming
Fixed a compile error in building the 85xx support with oprofile, and in the process cleaned up some issues with the fsl_booke performance monitor code. * Reorganized FSL Book-E performance monitoring code so that the 7450 wouldn't be built if the e500 was, and cleaned it up so it was more self-contained. * Added a cpu_setup function for FSL Book-E. The original cpu_setup function prototype had no arguments, assuming that the reg_setup function would copy the required information into variables which represented the registers. This was silly for e500, since it has 1 register per counter (rather than 3 for all counters), so the code has been restructured to have cpu_setup take the current counter config array as an argument, with op_powerpc_setup() invoking op_powerpc_cpu_setup() through on_each_cpu(), and op_powerpc_cpu_setup() invoking the model-specific cpu_setup function with an argument. The argument is ignored on all other platforms at present. * Fixed a confusing line where a trinary operator only had two arguments Signed-off-by: Andrew Fleming <afleming@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-06-09[PATCH] powerpc: oprofile support for POWER6Michael Neuling
POWER6 moves some of the MMCRA bits and also requires some bits to be cleared each PMU interrupt. Signed-off-by: Michael Neuling <mikey@neuling.org> Acked-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-03-29[PATCH] powerpc: Remove oprofile spinlock backtrace codeAnton Blanchard
Remove oprofile spinlock backtrace code now we have proper calltrace support. Also make MMCRA sihv and sipr bits a variable since they may change in future cpus. Finally, MMCRA should be a 64bit quantity. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-03-29[PATCH] powerpc: Add oprofile calltrace supportBrian Rogan
Add oprofile calltrace support to powerpc. Disable spinlock backtracing now we can use calltrace info. (Updated to work on both 32bit and 64bit by me). Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-03-22[PATCH] powerpc: Replace platform_is_lpar() with a firmware featureMichael Ellerman
It has been decreed that platform numbers are evil, so as a step in that direction, replace platform_is_lpar() with a FW_FEATURE_LPAR bit. Currently FW_FEATURE_LPAR really means i/pSeries LPAR, in the future we might have to clean that up if we need to be more specific about what LPAR actually means. But that's another patch ...

2006-01-09[PATCH] powerpc: Add a is_kernel_addr() macroMichael Ellerman
There's a bunch of code that compares an address with KERNELBASE to see if it's a "kernel address", ie. >= KERNELBASE. The proper test is actually to compare with PAGE_OFFSET, since we're going to change KERNELBASE soon. So replace all of them with an is_kernel_addr() macro that does that.

2005-11-11[PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernelBenjamin Herrenschmidt
This patch moves the vdso's to arch/powerpc, adds support for the 32 bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds some new (still untested) routines to both vdso's: clock_gettime() with support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same clocks) and get_tbfreq() for glibc to retreive the timebase frequency. Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits returns a long long (r3, r4) not a long. This is such that if we ever add support for >4Ghz timebases on ppc32, the userland interface won't have to change. I have tested gettimeofday() using some glibc patches in both ppc32 and ppc64 kernels using 32 bits userland (I haven't had a chance to test a 64 bits userland yet, but the implementation didn't change and was tested earlier). I haven't tested yet the new functions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-10[PATCH] powerpc: merge code values for identifying platformsPaul Mackerras
This patch merges platform codes. systemcfg->platform is no longer used, systemcfg use in general is deprecated as much as possible (and renamed _systemcfg before it gets completely moved elsewhere in a future patch), _machine is now used on ppc64 along as ppc32. Platform codes aren't gone yet but we are getting a step closer. A bunch of asm code in head[_64].S is also turned into C code.

2005-11-08[PATCH] ppc64: fix oprofile sample bit handlingAnton Blanchard
Oprofile was hardwiring the MMCRA sample bit to 1 but on newer cpus (eg POWER5) we want to vary it based on the group being sampled. Add a temporary workaround until people update their oprofile userspace. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
