  • d1bef4ed5   [PATCH] genirq: rename desc->handler to desc->chip ... Browse Code »

    This patch-queue improves the generic IRQ layer to be truly generic, by adding
    various abstractions and features to it, without impacting existing
    functionality.

    While the queue can be best described as "fix and improve everything in the
    generic IRQ layer that we could think of", and thus it consists of many
    smaller features and lots of cleanups, the one feature that stands out most is
    the new 'irq chip' abstraction.

    The irq-chip abstraction is about describing and coding and IRQ controller
    driver by mapping its raw hardware capabilities [and quirks, if needed] in a
    straightforward way, without having to think about "IRQ flow"
    (level/edge/etc.) type of details.

    This stands in contrast with the current 'irq-type' model of genirq
    architectures, which 'mixes' raw hardware capabilities with 'flow' details.
    The patchset supports both types of irq controller designs at once, and
    converts i386 and x86_64 to the new irq-chip design.

    As a bonus side-effect of the irq-chip approach, chained interrupt controllers
    (master/slave PIC constructs, etc.) are now supported by design as well.

    The end result of this patchset intends to be simpler architecture-level code
    and more consolidation between architectures.

    We reused many bits of code and many concepts from Russell King's ARM IRQ
    layer, the merging of which was one of the motivations for this patchset.

    This patch:

    rename desc->handler to desc->chip.

    Originally i did not want to do this, because it's a big patch. But having
    both "desc->handler", "desc->handle_irq" and "action->handler" caused a
    large degree of confusion and made the code appear alot less clean than it
    truly is.

    I have also attempted a dual approach as well by introducing a
    desc->chip alias - but that just wasnt robust enough and broke
    frequently.

    So lets get over with this quickly. The conversion was done automatically
    via scripts and converts all the code in the kernel.

    This renaming patch is the first one amongst the patches, so that the
    remaining patches can stay flexible and can be merged and split up
    without having some big monolithic patch act as a merge barrier.

  • d09042da7   [PATCH] fix incorrect SA_ONSTACK behaviour for 64-bit processes ... Browse Code »

    - When setting a sighandler using sigaction() call, if the flag
    SA_ONSTACK is set and no alternate stack is provided via sigaltstack(),
    the kernel still try to install the alternate stack. This behavior is
    the opposite of the one which is documented in Single Unix Specifications
    V3.

    - Also when setting an alternate stack using sigaltstack() with the flag
    SS_DISABLE, the kernel try to install the alternate stack on signal
    delivery.

    These two use cases makes the process crash at signal delivery.

  • 894b5779c   [PATCH] No arch-specific strpbrk implementations ... Browse Code »

    While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't
    being exported from lib/string.c. Investigating further, I noticed a
    changeset that removed its export and added it to _ksyms.c on a few more
    architectures. The justification was that "other arches do it."

    I think this is wrong, since no architecture currently defines
    __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it
    themselves. Therefore, consolidate the export to lib/string.c.

    CONFIG_TIME_LOW_RES is a temporary way for architectures to signal that
    they simply return xtime in do_gettimeoffset(). In this corner-case we
    want to round up by resolution when starting a relative timer, to avoid
    short timeouts. This will go away with the GTOD framework.

  • 5bfb5d690   [PATCH] sched: disable preempt in idle tasks ... Browse Code »

    Run idle threads with preempt disabled.

    Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
    How did it ever work before?

    Might fix the CPU hotplugging hang which Nigel Cunningham noted.

    We think the bug hits if the idle thread is preempted after checking
    need_resched() and before going to sleep, then the CPU offlined.

    After calling stop_machine_run, the CPU eventually returns from preemption and
    into the idle thread and goes to sleep. The CPU will continue executing
    previous idle and have no chance to call play_dead.

    By disabling preemption until we are ready to explicitly schedule, this bug is
    fixed and the idle threads generally become more robust.

  • 481bed454   [PATCH] consolidate sys_ptrace() ... Browse Code »

    The sys_ptrace boilerplate code (everything outside the big switch
    statement for the arch-specific requests) is shared by most architectures.
    This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
    arch_ptrace.

    Some architectures have a too different ptrace so we have to exclude them.
    They continue to keep their implementations. For sh64 I had to add a
    sh64_ptrace wrapper because it does some initialization on the first call.
    For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
    SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

  • 69be8f189   [PATCH] convert signal handling of NODEFER to act like other Unix boxes. ... Browse Code »

    It has been reported that the way Linux handles NODEFER for signals is
    not consistent with the way other Unix boxes handle it. I've written a
    program to test the behavior of how this flag affects signals and had
    several reports from people who ran this on various Unix boxes,
    confirming that Linux seems to be unique on the way this is handled.

    The way NODEFER affects signals on other Unix boxes is as follows:

    1) If NODEFER is set, other signals in sa_mask are still blocked.

    2) If NODEFER is set and the signal is in sa_mask, then the signal is
    still blocked. (Note: this is the behavior of all tested but Linux _and_
    NetBSD 2.0 *).

    The way NODEFER affects signals on Linux:

    1) If NODEFER is set, other signals are _not_ blocked regardless of
    sa_mask (Even NetBSD doesn't do this).

    2) If NODEFER is set and the signal is in sa_mask, then the signal being
    handled is not blocked.

    The patch converts signal handling in all current Linux architectures to
    the way most Unix boxes work.

    Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU
    3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX.

    * NetBSD was the only other Unix to behave like Linux on point #2. The
    main concern was brought up by point #1 which even NetBSD isn't like
    Linux. So with this patch, we leave NetBSD as the lonely one that
    behaves differently here with #2.

    To implement this all architectures has to source "net/Kconfig" before
    drivers/*/Kconfig in their Kconfig file. This change has been
    implemented for all architectures.

    Device drivers for ordinary NIC's are still to be found

    are located with their corresponding menu entries under the new
