  • a5598ca0d   powerpc/oprofile: Fix mutex locking for cell spu-oprofile ... Browse Code »

    The issue is the SPU code is not holding the kernel mutex lock while
    adding samples to the kernel buffer.

    This patch creates per SPU buffers to hold the data. Data
    is added to the buffers from in interrupt context. The data
    is periodically pushed to the kernel buffer via a new Oprofile
    function oprofile_put_buff(). The oprofile_put_buff() function
    is called via a work queue enabling the funtion to acquire the
    mutex lock.

    The existing user controls for adjusting the per CPU buffer
    size is used to control the size of the per SPU buffers.
    Similarly, overflows of the SPU buffers are reported by
    incrementing the per CPU buffer stats. This eliminates the
    need to have architecture specific controls for the per SPU
    buffers which is not acceptable to the OProfile user tool
    maintainer.

    The export of the oprofile add_event_entry() is removed as it
    is no longer needed given this patch.

    Note, this patch has not addressed the issue of indexing arrays
    by the spu number. This still needs to be fixed as the spu
    numbering is not guarenteed to be 0 to max_num_spus-1.

  • 1474855d0   [CELL] oprofile: add support to OProfile for profiling CELL BE SPUs ... Browse Code »

    From: Maynard Johnson

    This patch updates the existing arch/powerpc/oprofile/op_model_cell.c
    to add in the SPU profiling capabilities. In addition, a 'cell' subdirectory
    was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code.
    Exports spu_set_profile_private_kref and spu_get_profile_private_kref which
    are used by OProfile to store private profile information in spufs data
    structures.

    Also incorporated several fixes from other patches (rrn). Check pointer
    returned from kzalloc. Eliminated unnecessary cast. Better error
    handling and cleanup in the related area. 64-bit unsigned long parameter
    was being demoted to 32-bit unsigned int and eventually promoted back to
    unsigned long.

  • d54b1fdb1   [PATCH] mark struct file_operations const 5 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 0c0a400d1   [PATCH] oprofile: report anonymous region samples ... Browse Code »

    The below patch passes samples from anonymous regions to userspace instead
    of just dropping them. This provides the support needed for reporting
    anonymous-region code samples (today: basic accumulated results; later:
    Java and other dynamically compiled code).

    As this changes the format, an upgrade to the just-released 0.9 release of
    the userspace tools is required.

    This patch is based upon an earlier one by Will Cohen

    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!
