powerpc: Move a bunch of ppc64 headers to include/asm-powerpc

2005-11-14T06:22:01+00:00

... and also delete some that are no longer used because we already had an include/asm-powerpc version of the header. Signed-off-by: Paul Mackerras

ppc64: Add declarations to ppc64 headers as well as powerpc headers

2005-11-10T05:06:30+00:00

For now, we need these declarations that we moved from C code in the asm-ppc64 versions of these headers as well as the asm-powerpc versions. The asm-ppc64 versions will be disappearing shortly. Signed-off-by: Paul Mackerras

[PATCH] ppc64: support 64k pages

2005-11-07T00:56:47+00:00

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: Fix bug arising from having multiple memory_limit variables

2005-10-31T02:07:02+00:00

We had a static memory_limit in prom.c, and then another one defined in setup_64.c and used in numa.c, which resulted in the kernel crashing when mem=xxx was given on the command line. This puts the declaration in system.h and the definition in mem.c. This also moves the definition of tce_alloc_start/end out of setup_64.c. Signed-off-by: Paul Mackerras

[PATCH] powerpc: Fix handling of fpscr on 64-bit

2005-10-27T10:48:50+00:00

The recent merge of fpu.S broken the handling of fpscr for ARCH=powerpc and CONFIG_PPC64=y. FP registers could be corrupted, leading to strange random application crashes. The confusion arises, because the thread_struct has (and requires) a 64-bit area to save the fpscr, because we use load/store double instructions to get it in to/out of the FPU. However, only the low 32-bits are actually used, so we want to treat it as a 32-bit quantity when manipulating its bits to avoid extra load/stores on 32-bit. This patch replaces the current definition with a structure of two 32-bit quantities (pad and val), to clarify things as much as is possible. The 'val' field is used when manipulating bits, the structure itself is used when obtaining the address for loading/unloading the value from the FPU. While we're at it, consolidate the 4 (!) almost identical versions of cvt_fd() and cvt_df() (arch/ppc/kernel/misc.S, arch/ppc64/kernel/misc.S, arch/powerpc/kernel/misc_32.S, arch/powerpc/kernel/misc_64.S) into a single version in fpu.S. The new version takes a pointer to thread_struct and applies the correct offset itself, rather than a pointer to the fpscr field itself, again to avoid confusion as to which is the correct field to use. Finally, this patch makes ARCH=ppc64 also use the consolidated fpu.S code, which it previously did not. Built for G5 (ARCH=ppc64 and ARCH=powerpc), 32-bit powermac (ARCH=ppc and ARCH=powerpc) and Walnut (ARCH=ppc, CONFIG_MATH_EMULATION=y). Booted on G5 (ARCH=powerpc) and things which previously fell over no longer do. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras

powerpc: Merge in 64-bit powermac support.

2005-10-22T06:02:39+00:00

This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to arch/powerpc/platforms/powermac/*.c and makes various minor tweaks elsewhere. On the powermac we now initialize ppc_md by copying the whole pmac_md structure into it, which required some changes in the ordering of initializations of individual fields of it.

ppc64: Use merged versions of init_task.c and process.c.

2005-10-11T12:09:48+00:00

These two files are now built in arch/powerpc/kernel instead of arch/ppc64/kernel. Signed-off-by: Paul Mackerras

powerpc: Merged processor.h.

2005-10-10T04:19:43+00:00

This adds register definitions from the ppc64 processor.h to reg.h, and makes a single merged processor.h. I moved __is_processor from the ppc64 system.h to the merged reg.h along with the PVR register constants. Signed-off-by: Paul Mackerras

[PATCH] powerpc: merge atomic.h, memory.h

2005-09-25T12:38:46+00:00

powerpc: Merge atomic.h and memory.h into powerpc Merged atomic.h into include/powerpc. Moved asm-style HMT_ defines from memory.h into ppc_asm.h, where there were already HMT_defines; moved c-style HMT_ defines to processor.h. Renamed memory.h to synch.h to better reflect its contents.
