2010-10-13powerpc/Makefiles: Change to new flag variablesmatt mooney
Replace EXTRA_CFLAGS with ccflags-y and EXTRA_AFLAGS with asflags-y. Signed-off-by: matt mooney <mfm@muteddisk.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-08-20powerpc: Enable GCOVMichael Ellerman
Make it possible to enable GCOV code coverage measurement on powerpc. Lightly tested on 64-bit, seems to work as expected. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-06-16powerpc: Add configurable -Werror for arch/powerpcMichael Ellerman
Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2008-12-23powerpc: Prepare xmon_save_regs for use with kdumpAnton Vorontsov
Today the arch/powerpc/xmon/setjmp.S file contains only the xmon_save_regs function. We want to use it for kdump purposes, so let's move the file into arch/powerpc/kernel/ and give the function a more generic name (ppc_save_regs).

2006-12-04[POWERPC] cell: fix building without spufsArnd Bergmann
It may be desireable to build a kernel for cell without spufs, e.g. as the initial kboot kernel. This requires that the SPU specific parts of the core dump and the xmon code depend on CONFIG_SPU_BASE instead of CONFIG_PPC_CELL. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2006-12-04[POWERPC] Make xmon disassembly optionalMichael Ellerman
While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2006-12-04[POWERPC] Add spu disassembly to xmonMichael Ellerman
This patch adds a "sdi" command to xmon, to disassemble the contents of an spu's local store. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2006-01-09[PATCH] powerpc: Unify udbg (#2)Benjamin Herrenschmidt
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.

2005-11-08powerpc: Simplify and clean up the xmon terminal I/OPaul Mackerras
This factors out the common bits of arch/powerpc/xmon/start_*.c into a new nonstdio.c, and removes some stuff that was supposed to make xmon's I/O routines somewhat stdio-like but was never used. It also makes the parsing of the xmon= command line option common, so that ppc32 can now use xmon={off,on,early} also. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-28powerpc: Merge xmonPaul Mackerras
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').
