• ca078bae8   [PATCH] swsusp: switch pm_message_t to struct ... Browse Code »

  This adds type-checking to pm_message_t, so that people can't confuse it
  with int or u32. It also allows us to fix "disk yoyo" during suspend (disk
  spinning down/up/down).

  [We've tried that before; since that cpufreq problems were fixed and I've
  tried make allyes config and fixed resulting damage.]

  I think we need this patch or we might "lose" devices to the dpm_irq_off
  list if a failure occurs during the suspend process.

• af70316af   [PATCH] Add a semaphore to struct device to synchronize calls to its driver. ... Browse Code »

  This adds a per-device semaphore that is taken before every call from the core to a
  driver method. This prevents e.g. simultaneous calls to the ->suspend() or ->resume()
  and ->probe() or ->release(), potentially saving a whole lot of headaches.

  It also moves us a step closer to removing the bus rwsem, since it protects the fields
  in struct device that are modified by the core.

• 82428b62a   [PATCH] Driver Core: pm diagnostics update, check for errors ... Browse Code »

  This patch includes various tweaks in the messaging that appears during
  system pm state transitions:

  * Warn about certain illegal calls in the device tree, like resuming
  child before parent or suspending parent before child. This could
  happen easily enough through sysfs, or in some cases when drivers
  use device_pm_set_parent().

  * Be more consistent about dev_dbg() tracing ... do it for resume() and
  shutdown() too, and never if the driver doesn't have that method.

  * Say which type of system sleep state is being entered.

  Except for the warnings, these only affect debug messaging.

  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!
