  • 9caebec7b   [AVR32] optimize pagefault path ... Browse Code »

    Avoid the costly notifier list in the pagefault path and call
    the kprobes code directly. The same change went into the 2.6.22
    cycle for powerpc, 2s390 and sparc64 already.

  • 1eeb66a1b   move die notifier handling to common code ... Browse Code »

    This patch moves the die notifier handling to common code. Previous
    various architectures had exactly the same code for it. Note that the new
    code is compiled unconditionally, this should be understood as an appel to
    the other architecture maintainer to implement support for it aswell (aka
    sprinkling a notify_die or two in the proper place)

    arm had a notifiy_die that did something totally different, I renamed it to
    arm_notify_die as part of the patch and made it static to the file it's
    declared and used at. avr32 used to pass slightly less information through
    this interface and I brought it into line with the other architectures.

  • 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.
