  • 943aee0c6   Blackfin: SMP: make all barriers handle cache issues ... Browse Code »

    When suspending/resuming, the common task freezing code will run in
    parallel and freeze processes on each core. This is because the code
    uses the non-smp version of memory barriers (as well it should).

    The Blackfin smp barrier logic at the moment contains the cache sync
    logic, but the non-smp barriers do not. This is incorrect as Rafel
    summarized:
    > ...
    > The existing memory barriers are SMP barriers too, but they are more
    > than _just_ SMP barriers. At least that's how it is _supposed_ to be
    > (eg. rmb() is supposed to be stronger than smp_rmb()).
    > ...
    > However, looking at the blackfin's definitions of SMP barriers I see
    > that it uses extra stuff that should _also_ be used in the definitions
    > of the mandatory barriers.
    > ...

  • 3b139cdb3   Blackfin: Rename IRQ flags handling functions ... Browse Code »

    Rename h/w IRQ flags handling functions to be in line with what is expected for
    the irq renaming patch. This renames local_*_hw() to hard_local_*() using the
    following perl command:

    perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"`

    and then fixing up asm/irqflags.h manually.

    Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both
    return the flags rather than passing it through the argument list.

  • 96f1050d3   Blackfin: mass clean up of copyright/licensing info ... Browse Code »

    Bill Gatliff & David Brownell pointed out we were missing some
    copyrights, and licensing terms in some of the files in
    ./arch/blackfin, so this fixes things, and cleans them up.

    It also removes:
    - verbose GPL text(refer to the top level ./COPYING file)
    - file names (you are looking at the file)
    - bug url (it's in the ./MAINTAINERS file)
    - "or later" on GPL-2, when we did not have that right

    It also allows some Blackfin-specific assembly files to be under a BSD
    like license (for people to use them outside of Linux).
