  • 8b5690f88   MIPS: 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.

    [ralf@linux-mips.org: Fixed up conflicts in
    arch/mips/alchemy/common/dbdma.c, arch/mips/cavium-octeon/smp.c and
    arch/mips/kernel/perf_event.c.]

  • 3e5c12409   set_rtc_mmss: show warning message only once ... Browse Code »

    Occasionally the system gets into a state where the CMOS clock has gotten
    slightly ahead of current time and the periodic update of RTC fails. The
    message is a nuisance and repeats spamming the log.

    See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS

    Rather than just removing the message, make it show only once and reduce
    severity since it indicates a normal and non urgent condition.

  • ad4b2b627   MIPS: Repair Kbuild make clean breakage. ... Browse Code »

    When running make clean, Kbuild doesn't process the .config file, so nothing
    generates a platform-y variable. We can get it to descend into the platform
    directories by setting $(obj-).

    The dec Platform file was unconditionally setting platform-, obliterating
    its previous contents and preventing some directories from being cleaned.
    This is change to an append operation '+=' to allow cavium-octeon to be
    cleaned.

    This is required for the patch to sort out irqflags handling function naming to

  • 36de48de8   [MIPS] DECstation: Optimised early printk() ... Browse Code »

    This is an optimised implementation of early printk() for the DECstation.
    After the recent conversion to a MIPS-specific generic routine using a
    character-by-character output the performance dropped significantly.
    This change reverts to the previous speed -- even at 9600 bps of the
    serial console the difference is visible with a naked eye; I presume for a
    framebuffer it is even worse (it may depend on exactly which one is used
    though).

    Additionally the change includes a fix for a problem that the old
    implementation had -- the format used would not actually limit the length
    of the string output. This new implementation uses a local buffer to deal
    with it -- even with this additional copying it is much faster than the
    generic function.

    Plus this driver is registered much earlier than the generic one,
    allowing one to see critical messages, such as one about an incorrect CPU
    setting used, that are produced beforehand. :-)

    is redundant while AFLAGS contains $(cflags-y) and any options only

    When I post a patch (commit f431baa55abf8adeed0c718b51deacbc151f58f1),
    I just tried to not change behavior of existing codes, but it seems
    dec/int-handler.S had been broken since its previous commit
    937a801576f954bd030d7c4a5a94571710d87c0b.

    The caller of plat_irq_dispatch do setup/restore TI_REGS($28), so
    dec's plat_irq_dispatch should not do it, and there is no need to
    adjust RA.

  • 97dcb82de   [MIPS] Define MIPS_CPU_IRQ_BASE in generic header ... Browse Code »

    The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all
    platforms and are same value on most platforms (0 or 16, depends on
    CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make
    them customizable. This will save a few cycle on each CPU interrupt.

    A good side effect is removing some dependencies to MALTA in generic
    SMTC code.

    Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq
    mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing
    them might cause some header dependency problem and there seems no
    good reason to customize it. So currently only VR41XX is using custom
    MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259.

    Testing this patch on those platforms is greatly appreciated. Thank
    you.
