[POWERPC] Add starting of secondary 86xx CPUs.

2006-06-21T05:01:28Z

Clear the high BATS during load_up_mmu if FTR_HAS_HIGH_BATS. Allow just a bit more time for secondary CPUs to phone home. Signed-off-by: Wei Zhang Signed-off-by: Haiying Wang Signed-off-by: Jon Loeliger Signed-off-by: Paul Mackerras

[PATCH] powerpc: fix altivec_unavailable_exception Oopses

2006-02-24T00:36:23Z

altivec_unavailable_exception is called without setting r3... it looks like the r3 that actually gets passed in as struct pt_regs *regs is the undisturbed value of r3 at the time the altivec instruction was encountered. The user actually gets to choose the pt_regs printed in the Oops! This fixes the oops by passing the correct pt_regs pointer to altivec_unavailable_exception.

powerpc: set CONFIG_PPC_OF=y always for ARCH=powerpc

2006-01-09T09:17:01Z

The CONFIG_PPC_OF symbol is used to mean that the firmware device tree access functions are available. Since we always have a device tree with ARCH=powerpc, make CONFIG_PPC_OF always Y for ARCH=powerpc. This fixes some compile errors reported by Kumar Gala, but in a different way to his patch. This also makes prom_parse.o be compiled only if CONFIG_PPC_OF so that non-OF ARCH=ppc platforms will compile. Signed-off-by: Paul Mackerras

[PATCH] powerpc: G4+ oprofile support

2006-01-09T04:06:03Z

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 Signed-off-by: Paul Mackerras

[PATCH] powerpc: Add back support for booting from BootX (#2)

2006-01-09T03:49:58Z

ARCH=powerpc couldn't boot from BootX as it uses a "different" way of getting in the kernel. This patch adds the necessary trampolines, creating a flattened device-tree from the tree passed from MacOS, and initializing the btext engine early for really-early debugging.

[PATCH] powerpc: Unify udbg (#2)

2006-01-09T03:49:54Z

This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

powerpc: Initialize secondary CPU setup for 32-bit SMP

2005-11-11T11:34:43Z

32-bit SMP powermacs weren't booting with ARCH=powerpc because the boot cpu wasn't saving away the state of various control registers, but the secondary CPUs were loading them from the uninitialized state. This adds the necessary save-state call. Signed-off-by: Paul Mackerras

powerpc: Merge xmon

2005-10-28T12:53:37Z

The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').
