  • d11584a04   SH: irq: Remove IRQF_DISABLED ... Browse Code »

    Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled
    and we even check and yell when an interrupt handler
    returns with interrupts enabled (see commit [b738a50a:
    genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • 2f55ac072   suspend: constify platform_suspend_ops ... Browse Code »

    While at it, fix two checkpatch errors.
    Several non-const struct instances constified by this patch were added after
    the introduction of platform_suspend_ops in checkpatch.pl's list of "should
    be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73).

    Patch against mainline.
    Inspired by hunks of the grsecurity patch, updated for newer kernels.

  • 9d56dd3b0   sh: Mass ctrl_in/outX to __raw_read/writeX conversion. ... Browse Code »

    The old ctrl in/out routines are non-portable and unsuitable for
    cross-platform use. While drivers/sh has already been sanitized, there
    is still quite a lot of code that is not. This converts the arch/sh/ bits
    over, which permits us to flag the routines as deprecated whilst still
    building with -Werror for the architecture code, and to ensure that
    future users are not added.

  • 9dcaa7b25   ALSA: sh: add SuperH DAC audio driver for ALSA V4 ... Browse Code »

    This is a port of the sound/oss/sh_dac_audio.c driver.
    The driver uses an on-chip 8-bit D/A converter, which has a speaker connected
    to one of its channels, found in several ancient HP machines.
    For interrupts it uses a high-resolution timer (hrtimer).
    Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).

    Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver
    would be obsolete soon, and it could be removed.

  • 1d015cf02   sh: shared register saving code for sh3/sh4/sh4a ... Browse Code »

    This patch reworks the sh3/sh4/sh4a register saving code in
    the following ways:
    - break out prepare_stack_save_dsp() from handle_exception()
    - break out save_regs() from handle_exception()
    - the register saving order is unchanged
    - align new functions to fit in cache lines
    - separate exception code from interrupt code
    - keep main code flow in a single cache line per exception vector
    - use bsr/rts for regular functions (save pr first)
    - keep data in one shared cache line (exception_data)
    - document the functions
    - tie in the hp6xx code

  • 3e5176275   sh: move the hp6xx pm code ... Browse Code »

    Move the not-so-generic pm code from arch/sh/kernel/pm.c to the
    platform directory together with the rest of the hp6xx pm code.

    This is done to let non-hp6xx platforms enable CONFIG_PM.
