  • e63fb7a9d   MIPS: Octeon: Mark SMP-IPI interrupt as IRQF_NO_THREAD ... Browse Code »

    This is to exclude it from force threading to allow RT patch set to work.
    And while on this line
    * Remove IRQF_DISABLED as as this flag is NOOP
    * Add IRQF_PERCPU as this is a per cpu interrupt.

  • 184748cc5   sched: Provide scheduler_ipi() callback in response to smp_send_reschedule() ... Browse Code »

    For future rework of try_to_wake_up() we'd like to push part of that
    function onto the CPU the task is actually going to run on.

    In order to do so we need a generic callback from the existing scheduler IPI.

    This patch introduces such a generic callback: scheduler_ipi() and
    implements it as a NOP.

    BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!

  • 0c3263870   MIPS: Octeon: Rewrite interrupt handling code. ... Browse Code »

    This includes conversion to new style irq_chip functions, and
    correctly enabling/disabling per-CPU interrupts.

    The hardware interrupt bit to irq number mapping is now done with a
    flexible map, instead of by bit twiddling the irq number.

    [ tglx: Adjusted to new irq_cpu_on/offline callbacks and
    __irq_set_affinity_lock ]

    * Rename camel-case InitTLBStart_addr to octeon_bootloader_entry_addr.

    * Convert calls to cvmx_read64_uint32(), to simple pointer
    dereferences.

    * Set proper ebase.

    * Don't confuse coreid and cpu numbers.

    * Try to maintain consistent bootloader coremask.

    * Update the signature and boot_init_vector of supported bootloaders.

  • 39b3d4462   MIPS: Octeon: Run IPI code with interrupts disabled. ... Browse Code »

    In mm/slab.c the function do_ccupdate_local requires that interrupts be
    disabled. If they are not, we panic with CONFIG_DEBUG_SLAB.

    So we disable interrupts while processing IPIs. Also these are not shared
    irqs, so get rid of the IRQF_SHARED flag.

    These are the rest of the new files needed to add OCTEON processor
    support to the Linux kernel. Other than Makefile and Kconfig which
    should be obvious, we have:

    csrc-octeon.c -- Clock source driver for OCTEON.
    dma-octeon.c -- Helper functions for mapping DMA memory.
    flash_setup.c -- Register on-board flash with the MTD subsystem.
    octeon-irq.c -- OCTEON interrupt controller managment.
    octeon-memcpy.S -- Optimized memcpy() implementation.
    serial.c -- Register 8250 platform driver and early console.
    setup.c -- Early architecture initialization.
    smp.c -- OCTEON SMP support.
    octeon_switch.S -- Scheduler context switch for OCTEON.
    c-octeon.c -- OCTEON cache controller support.
    cex-oct.S -- OCTEON cache exception handler.

    asm/mach-cavium-octeon/*.h -- Architecture include files.
