2016-03-01sparc32: Add -Wa,-Av8 to KBUILD_CFLAGS.David S. Miller1-0/+6
Binutils used to be (erroneously) extremely permissive about instruction usage. But that got fixed and if you don't properly tell it to accept classes of instructions it will fail. This uncovered a specs bug on sparc in gcc where it wouldn't pass the proper options to binutils options. Deal with this in the kernel build by adding -Wa,-Av8 to KBUILD_CFLAGS.

2013-03-20sparc64: Hibernation supportTkhai Kirill1-0/+1
This patch adds CONFIG_HIBERNATION support for sparc64 architecture. The suspend function is the same as on another platforms. The restore function uses Bypass feature of MMU which allows to make the process more comfortable and plesant.

2012-03-13sparc32: Add -Av8 to assembler command line.David S. Miller1-1/+1
Newer version of binutils are more strict about specifying the correct options to enable certain classes of instructions. The sparc32 build is done for v7 in order to support sun4c systems which lack hardware integer multiply and divide instructions. So we have to pass -Av8 when building the assembler routines that use these instructions and get patched into the kernel when we find out that we have a v8 capable cpu.

2009-12-05sparc: Set UTS_MACHINE correctly.David S. Miller1-0/+2
"ARCH" can be just about anything, so we shouldn't end up with UTS_MACHINE of "sparc" in a 64-bit kernel build just because someone set the personality using 'sparc32' or similar. CONFIG_SPARC64 drives the compilation and therefore provides the definitive value, not "ARCH". This mirrors commit 8c6531f7a99f29ba8817ffb12cc9ecf190049bd6 (x86: correctly set UTS_MACHINE for "make ARCH=x86") Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-20arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0Sam Ravnborg1-4/+0
Albin Tonnerre <albin.tonnerre@free-electrons.com> reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

2008-12-04sparc,sparc64: unify prom/Sam Ravnborg1-2/+1
- all files with identical names copied and renamed to *_64.c - the remaning files copied as is - added sparc64 specific files to sparc/prom/Makefile - teach sparc64 Makefile to look into sparc/prom/ - delete unused Makefile from sparc64/prom/ linking order was not kept for sparc64 with this change. It was not possible to keep linking order for both sparc and sparc64 and as sparc64 see more testing than sparc it was natural to break linking order on sparc64. Should it have any effect it would be detected sooner this way. printf_32.c and printf_64.c are obvious candidates to be merged but they are not 100% equal so that was left for later Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

2008-12-04sparc,sparc64: unify MakefileSam Ravnborg1-13/+69
To unify Makefile for sparc and sparc64 a few other steps was needed: 1) separate defconfig files for sparc and sparc64 is required, so locate these in arch/sparc/configs 2) removoval of hack in toplevel Makefile to deal with that headers was in a separate directory compared to the rest The unification of the Makefile required usage of several foo-$(CONFIG_SPARCnn) += due to a few directories pending unification. This will be cleaned up when we unify the remaining directories. Included in this patch are the deletion of a few files in sparc64 as they are no longer needed: Makefile + Kconfig. arch/sparc64/ will after this patch is applied only have four directories (prom, lib, kernel, boot) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

2007-10-15kbuild: enable 'make AFLAGS=...' to add additional options to ASSam Ravnborg1-1/+1
The variable AFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of AFLAGS with KBUILD_AFLAGS all over the tree. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390 Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+78
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
