• 37ca5eb34   oprofile: set values to default when creating oprofilefs ... Browse Code »

  This patch restores default values for:

  /dev/oprofile/cpu_buffer_size
  /dev/oprofile/buffer_watershed
  /dev/oprofile/buffer_size

  when creating the oprofilefs:

  # opcontrol --deinit
  # opcontrol --init
  # cat /dev/oprofile/cpu_buffer_size
  8192
  # echo 5123 > /dev/oprofile/cpu_buffer_size
  # cat /dev/oprofile/cpu_buffer_size
  5123
  # opcontrol --deinit
  # opcontrol --init
  # cat /dev/oprofile/cpu_buffer_size
  8192
  # opcontrol --deinit

  This sets the values in a defined state. Before, there was no way to
  restore the defaults without rebooting the system or reloading the
  module.

  This patch introduces multiplexing support for the Oprofile kernel
  module. It basically adds a new function pointer in oprofile_operator
  allowing each architecture to supply its callback to switch between
  different sets of event when the timer expires. Userspace tools can
  modify the time slice through /dev/oprofile/time_slice.

  It also modifies the number of counters exposed to the userspace through
  /dev/oprofile. For example, the number of counters for AMD CPUs are
  changed to 32 and multiplexed in the sets of 4.

• 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.

  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!
