[PATCH] powerpc32: Set cpu explicitly in kernel compiles

2006-04-13T16:38:33Z

Compile the 32bit kernel with -mcpu=powerpc. This reduces the imagesize when a compiler is used that defaults to -mtune=power4. It inserts lots of nops to please the 64bit cpu instruction scheduling. But all these nops are not needed for 32bit kernels. Example with SLES10 gcc 4.1.0 and arch/powerpc/configs/pmac32_defconfig: vmlinux vmlinux.strip vmlinux.gz -O2 4980515 4187528 1846829 -Os 4618801 3827084 1673333 -O2 -mcpu=powerpc 4738851 3945868 1816253 -Os -mcpu=powerpc 4532785 3741068 1664688 Signed-off-by: Olaf Hering Signed-off-by: Paul Mackerras

powerpc: move math-emu over to arch/powerpc

2006-03-28T05:43:27Z

Towards the goal of having arch/powerpc not build anything over in arch/ppc move math-emu over. Also, killed some references to arch/ppc/ in the arch/powerpc Makefile which should belong in drivers/ when the particular sub-arch's move over to arch/powerpc. Signed-off-by: Kumar Gala

powerpc: Don't compile in arch/ppc/kernel for 32-bit ARCH=powerpc

2006-03-27T09:17:06Z

All of the things needed for 32-bit ARCH=powerpc builds have now moved to arch/powerpc/kernel, so we don't need to go down into arch/ppc/kernel any more, and we can remove the CONFIG_PPC_MERGE conditional from arch/ppc/kernel/Makefile. There were two files still referenced in the merge section of arch/ppc/kernel/Makefile: ppc-stub.o, depending on CONFIG_KGDB, and dma-mapping.o, depending on CONFIG_NOT_COHERENT_CACHE. None of the platforms currently in ARCH=powerpc have caches that aren't coherent with DMA, but when we do get one we'll move dma-mapping.c over. As for CONFIG_KGDB, none of the Kconfig files in the tree define it, so I'll let it languish for now. Signed-off-by: Paul Mackerras

kbuild: change kbuild to not rely on incorrect GNU make behavior

2006-03-05T23:09:51Z

The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

[PATCH] Fix building external modules on ppc32

2006-02-10T16:13:12Z

We are setting up sources for building external modules like this: /usr/src/linux-obj> # create a .config file /usr/src/linux-obj> make -C /usr/src/linux O=$PWD oldconfig /usr/src/linux-obj> make -C /usr/src/linux O=$PWD prepare /usr/src/linux-obj> make -C /usr/src/linux O=$PWD scripts /usr/src/linux-obj> make -C /usr/src/linux O=$PWD clean After that, external modules can be built with: /usr/src/module> make -C /usr/src/linux-obj M=$PWD This fails for ppc32 because the `make clean' removes the arch/powerpc/include directory. This should be done in archmrproper instead of in archclean.

[PATCH] powerpc: Add CONFIG_DEFAULT_UIMAGE for embedded boards

2006-02-10T06:15:01Z

Embedded boards that u-boot require a kernel image in the uImage format. This allows a given board to specify it wants a uImage built by default. This also fixes a warning at config time, as this symbol is referred to in arch/powerpc/platforms/83xx/Kconfig. Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras
