      ALSA: pcm: Modify double acknowledged interrupts check condition · 13a98839
      Koro Chen authored
      
      
      Currently in snd_pcm_update_hw_ptr0 during interrupt,
      we consider there were double acknowledged interrupts when:
      1. HW reported pointer is smaller than expected, and
      2. Time from last update time (hdelta) is over half a buffer time.
      
      However, when HW reported pointer is only a few bytes smaller than
      expected, and when hdelta is just a little larger than half a buffer time
      (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged.
      
      The condition #2 uses jiffies, but jiffies is not high resolution
      since it is integer. We should consider jiffies inaccuracy.

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored
      Since commit 844b03f2
      
       we make
      sure that after vblank irq off, we return the last valid
      (vblank count, vblank timestamp) pair to clients, e.g., during
      modesets, which is good.
      
      An overlooked side effect of that commit for kms drivers without
      support for precise vblank timestamping is that at vblank irq
      enable, when we update the vblank counter from the hw counter, we
      can't update the corresponding vblank timestamp, so now we have a
      totally mismatched timestamp for the new count to confuse clients.
      
      Restore old client visible behaviour from before Linux 3.17, but
      zero out the timestamp at vblank counter update (instead of disable
      as in original implementation) if we can't generate a meaningful
      timestamp immediately for the new vblank counter. This will fix
      this regression, so callers know they need to retry again later
      if they need a valid timestamp, but at the same time preserves
      the improvements made in the commit mentioned above.
