  • 6451d7783   arm: remove machine_desc.io_pg_offst and .phys_io ... Browse Code »

    Since we're now using addruart to establish the debug mapping, we can
    remove the io_pg_offst and phys_io members of struct machine_desc.

    The various declarations were removed using the following script:

    grep -rl MACHINE_START arch/arm | xargs \
    sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

    [ Initial patch was from Jeremy Kerr, example script from Russell King ]

  • df0698be1   ARM: stack protector: change the canary value per task ... Browse Code »

    A new random value for the canary is stored in the task struct whenever
    a new task is forked. This is meant to allow for different canary values
    per task. On ARM, GCC expects the canary value to be found in a global
    variable called __stack_chk_guard. So this variable has to be updated
    with the value stored in the task struct whenever a task switch occurs.

    Because the variable GCC expects is global, this cannot work on SMP
    unfortunately. So, on SMP, the same initial canary value is kept
    throughout, making this feature a bit less effective although it is still
    useful.

    One way to overcome this GCC limitation would be to locate the
    __stack_chk_guard variable into a memory page of its own for each CPU,
    and then use TLB locking to have each CPU see its own page at the same
    virtual address for each of them.

  • 516793c61   [ARM] ARMv6: add CPU_HAS_ASID configuration ... Browse Code »

    Presently, we check for the minimum ARM architecture that we're
    building for to determine whether we need ASID support. This is
    wrong - if we're going to support a range of CPUs which include
    ARMv6 or higher, we need the ASID.

    Convert the checks to use a new configuration symbol, and arrange
    for ARMv6 and higher CPU entries to select it.

  • 8799ee9f4   [ARM] Set bit 4 on section mappings correctly depending on CPU ... Browse Code »

    On some CPUs, bit 4 of section mappings means "update the
    cache when written to". On others, this bit is required to
    be one, and others it's required to be zero. Finally, on
    ARMv6 and above, setting it turns on "no execute" and prevents
    speculative prefetches.

    With all these combinations, no one value fits all CPUs, so we
    have to pick a value depending on the CPU type, and the area
    we're mapping.

  • cdaabbd74   [ARM] iwmmxt thread state alignment ... Browse Code »

    This patch removes the reliance of iwmmxt on hand coded alignments.
    Since thread_info is always 8K aligned, specifying that fpstate is
    8-byte aligned achieves the same effect without needing to resort
    to hand coded alignments.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
