* [PATCH] powerpc: disable OProfile for iSeriesKelly Daly2006-02-23
| | | | | | | | Disable OProfile in Kconfig for iSeries to prevent hangs. OProfile was not originally intended to work with legacy iSeries. Signed-off-by: Kelly Daly <kelly@au.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: oprofile cpu type names clash with other codeAndy Whitcroft2006-01-13
| | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] ppc64: Fix oprofile when compiled as a moduleAnton Blanchard2006-01-09
| | | | | | | | | 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. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: G4+ oprofile supportAndy Fleming2006-01-08
| | | | | | | | | | | | | | | 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 Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Add a is_kernel_addr() macroMichael Ellerman2006-01-08
| | | | | | | | | | | 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.

* [PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernelBenjamin Herrenschmidt2005-11-11
| | | | | | | | | | | | | | | | | | | | | 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>
* [PATCH] powerpc: merge code values for identifying platformsPaul Mackerras2005-11-09
| | | | | | | | | | | | 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.

* [PATCH] ppc64: fix oprofile sample bit handlingAnton Blanchard2005-11-07
| | | | | | | | | | 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>
* [PATCH] Move Kprobes and Oprofile to "Instrumentation Support" menuPrasanna S Panchamukhi2005-11-07
| | | | | | | | | | | | | | | Andrew Morton suggested to move kprobes from kernel hacking menu, since kernel hacking menu is in-appropriate for the Kprobes. This patch moves Kprobes and Oprofile under instrumentation menu. (akpm: it's not a natural fit, but things like djprobes and the s390 guys' statistics library need a home) Signed-of-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Cc: Philippe Elie <phil.el@wanadoo.fr> Cc: John Levon <levon@movementarian.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] powerpc: Merge ppc64 pmc.[ch] with ppc32 perfmon.[ch]David Gibson2005-10-20
| | | | | | | | | | | | | | This patches the ppc32 and ppc64 versions of the headers and .c files with helper functions for manipulating the performance counting hardware. As a side effect, it removes use of the term "perfmon" from ppc32, thus avoiding confusion with the unrelated performance counter interface from HP Labs also called "perfmon". Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

* [PATCH] ppc32: make cur_cpu_spec a single pointer instead of an arrayKumar Gala2005-09-28
| | | | | | | | | | Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs. Additionally, made call_setup_cpu check to see if the cpu_setup pointer is NULL or not before calling the function. This lets remove the dummy cpu_setup calls that just return.
