* [PATCH] powerpc: oprofile cpu type names clash with other codeAndy Whitcroft2006-01-141-26/+26
| | | | | | | | | | | | | | | | | | | | | | 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 valuePaul Mackerras2006-01-141-44/+128
| | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] ppc64: POWER5+ oprofile supportAnton Blanchard2006-01-091-2/+2
| | | | | | | | POWER5+ adds new PMU groups and as such needs to be treated differently by oprofile userspace. Change it to report itself as power5+. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] ppc64: Fix oprofile when compiled as a moduleAnton Blanchard2006-01-091-78/+26
| | | | | | | | | 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] cell: enable pause(0) in cpu_idleArnd Bergmann2006-01-091-1/+1
| | | | | | | | | | | | 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 supportAndy Fleming2006-01-091-11/+63
| | | | | | | | | | | | | | | 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] ppc64: support 64k pagesBenjamin Herrenschmidt2005-11-061-2/+2
| | | | | | | | | | | | | | | Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

* powerpc: 32-bit needs cur_cpu_spec exported tooPaul Mackerras2005-10-291-2/+0
