  • b920de1b7   mn10300: add the MN10300/AM33 architecture to the kernel ... Browse Code »

    Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
    kernel.

    This patch also adds board support for the ASB2303 with the ASB2308 daughter
    board, and the ASB2305. The only processor supported is the MN103E010, which
    is an AM33v2 core plus on-chip devices.

  • 1474855d0   [CELL] oprofile: add support to OProfile for profiling CELL BE SPUs ... Browse Code »

    From: Maynard Johnson

    This patch updates the existing arch/powerpc/oprofile/op_model_cell.c
    to add in the SPU profiling capabilities. In addition, a 'cell' subdirectory
    was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code.
    Exports spu_set_profile_private_kref and spu_get_profile_private_kref which
    are used by OProfile to store private profile information in spufs data
    structures.

    Also incorporated several fixes from other patches (rrn). Check pointer
    returned from kzalloc. Eliminated unnecessary cast. Better error
    handling and cleanup in the related area. 64-bit unsigned long parameter
    was being demoted to 32-bit unsigned int and eventually promoted back to
    unsigned long.

  • 1394f0322   blackfin architecture ... Browse Code »

    This adds support for the Analog Devices Blackfin processor architecture, and
    currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561
    (Dual Core) devices, with a variety of development platforms including those
    avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP,
    BF561-EZKIT), and Bluetechnix! Tinyboards.

    The Blackfin architecture was jointly developed by Intel and Analog Devices
    Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in
    December of 2000. Since then ADI has put this core into its Blackfin
    processor family of devices. The Blackfin core has the advantages of a clean,
    orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC
    (Multiply/Accumulate), state-of-the-art signal processing engine and
    single-instruction, multiple-data (SIMD) multimedia capabilities into a single
    instruction-set architecture.

    The Blackfin architecture, including the instruction set, is described by the
    ADSP-BF53x/BF56x Blackfin Processor Programming Reference
    http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf

    The Blackfin processor is already supported by major releases of gcc, and
    there are binary and source rpms/tarballs for many architectures at:
    http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete
    documentation, including "getting started" guides available at:
    http://docs.blackfin.uclinux.org/ which provides links to the sources and
    patches you will need in order to set up a cross-compiling environment for
    bfin-linux-uclibc

    This patch, as well as the other patches (toolchain, distribution,
    uClibc) are actively supported by Analog Devices Inc, at:
    http://blackfin.uclinux.org/

    We have tested this on LTP, and our test plan (including pass/fails) can
    be found at:
    http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel

  • 5f97f7f94   [PATCH] avr32 architecture ... Browse Code »

    This adds support for the Atmel AVR32 architecture as well as the AT32AP7000
    CPU and the AT32STK1000 development board.

    AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for
    cost-sensitive embedded applications, with particular emphasis on low power
    consumption and high code density. The AVR32 architecture is not binary
    compatible with earlier 8-bit AVR architectures.

    The AVR32 architecture, including the instruction set, is described by the
    AVR32 Architecture Manual, available from

    http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf

    The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It
    features a 7-stage pipeline, 16KB instruction and data caches and a full
    Memory Management Unit. It also comes with a large set of integrated
    peripherals, many of which are shared with the AT91 ARM-based controllers from
    Atmel.

    Full data sheet is available from

    http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf

    while the CPU core implementation including caches and MMU is documented by
    the AVR32 AP Technical Reference, available from

    http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf

    Information about the AT32STK1000 development board can be found at

    http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918

    including a BSP CD image with an earlier version of this patch, development
    tools (binaries and source/patches) and a root filesystem image suitable for
    booting from SD card.

    Alternatively, there's a preliminary "getting started" guide available at
    http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links
    to the sources and patches you will need in order to set up a cross-compiling
    environment for avr32-linux.

    This patch, as well as the other patches included with the BSP and the
    toolchain patches, is actively supported by Atmel Corporation.
