MIPS: Fix MSA toolchain support detection.

2014-06-03T19:19:28Z

The '-mmsa' option is not supported by all current compilers. Change the detection to instead pass the option directly to the assembler. Signed-off-by: Steven J.

MIPS: SB1: Fix excessive kernel warnings.

2014-05-28T06:42:23Z

A kernel build with binutils 2.24 is going to emit warnings like CC kernel/sys.o {standard input}: Assembler messages: {standard input}:701: Warning: the 32-bit MIPS architecture does not support the `mdmx' extension {standard input}:701: Warning: the `mdmx' extension requires 64-bit FPRs {standard input}:701: Warning: the `mips3d' extension requires MIPS32 revision 2 or greater {standard input}:701: Warning: the `mips3d' extension requires 64-bit FPRs for almost every file. This is caused by changes to gas' interpretation of .set semantics. Fixed by explicitly disabling MIPS3D and MDMX for Sibyte builds. Signed-off-by: Ralf Baechle

MIPS: math-emu: Move various objects into an ar library.

2014-05-23T13:11:14Z

ieee754d.o contains only debug code and dp_sqrt.o and sp_sqrt.o contain code which for MIPS I/II/III systems we don't want to link.

MIPS: Add MSA register definitions & access

2014-03-26T22:09:10Z

This patch introduces definitions for the MSA control registers and functions which allow access to both the control & vector registers. If the toolchain being used to build the kernel includes support for MSA then this patch will make use of that support & use MSA instructions directly. However toolchain support for MSA is very new & far from a point where it can be reasonably expected that everyone building the kernel uses a toolchain with support. Thus fallbacks using .word assembler directives are also provided for now as a temporary measure.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2014-01-31T01:20:32Z

Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.

MIPS: microMIPS: Remove unsupported compiler flag.

2014-01-23T12:02:35Z

Remove usage of -mno-jals compiler flag when building a pure microMIPS kernel. The -mno-jals flag only ever existed within Mentor toolchains. Dropping this flag allows all FSF toolchains to work.

stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between architectures

2013-12-20T08:38:40Z

Instead of duplicating the CC_STACKPROTECTOR Kconfig and Makefile logic in each architecture, switch to using HAVE_CC_STACKPROTECTOR and keep everything in one place. This retains the x86-specific bug verification scripts.

MIPS: Kbuild: Do not allow building vmlinuz when !ZBOOT

2013-10-29T20:24:26Z

When CONFIG_SYS_SUPPORTS_ZBOOT is not enabled, we will still try to build the decompressor code in arch/mips/boot/compressed as a dependency for producing the vmlinuz target and this will result in the following build failure: OBJCOPY arch/mips/boot/compressed/vmlinux.bin arch/mips/boot/compressed/decompress.c: In function 'decompress_kernel': arch/mips/boot/compressed/decompress.c:105:2: error: implicit declaration of function 'decompress' make[1]: *** [arch/mips/boot/compressed/decompress.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [vmlinuz] Error 2 This is a genuine build failure because we have no implementation for the decompress() function body since no kernel compression method defined in CONFIG_KERNEL_(GZIP,BZIP2...) has been enabled. arch/mips/Makefile already guards the install target for the "vmlinuz" binary with a proper ifdef CONFIG_SYS_SUPPORTS_ZBOOT, we now also do the same if we attempt to do a "make vmlinuz" and show that CONFIG_SYS_SUPPORTS_ZBOOT is not enabled.
