      drm/i915: Fix incorrect definition of ADPA HSYNC and VSYNC bits · 60222c0c
      Patrik Jakobsson 提交于
      Disable bits for ADPA HSYNC and VSYNC where mixed up resulting in suspend
      becoming standby and vice versa. Fixed by swapping their bit position.

      drm/i915: also disable south interrupts when handling them · 44498aea
      Paulo Zanoni 提交于
      From the docs:
      
        "IIR can queue up to two interrupt events. When the IIR is cleared,
        it will set itself again after one clock if a second event was
        stored."
      
        "Only the rising edge of the PCH Display interrupt will cause the
        North Display IIR (DEIIR) PCH Display Interrupt even bit to be set,
        so all PCH Display Interrupts, including back to back interrupts,
        must be cleared before a new PCH Display interrupt can cause DEIIR
        to be set".
      
      The current code works fine because we don't get many interrupts, but
      if we enable the PCH FIFO underrun interrupts we'll start getting so
      many interrupts that at some point new PCH interrupts won't cause
      DEIIR to be set.
      
      The initial implementation I tried was to turn the code that checks
      SDEIIR into a loop, but we can still get interrupts even after the
      loop is done (and before the irq handler finishes), so we have to
      either disable the interrupts or mask them. In the end I concluded
      that just disabling the PCH interrupts is enough, you don't even need
      the loop, so this is what this patch implements. I've tested it and it
      passes the 2 "PCH FIFO underrun interrupt storms" I can reproduce:
      the "ironlake_crtc_disable" case and the "wrong watermarks" case.
      
      In other words, here's how to reproduce the problem fixed by this
      patch:
        1 - Enable PCH FIFO underrun interrupts (SERR_INT on SNB+)
        2 - Boot the machine
        3 - While booting we'll get tons of PCH FIFO underrun interrupts
        4 - Plug a new monitor
        5 - Run xrandr, notice it won't detect the new monitor
        6 - Read SDEIIR and notice it's not 0 while DEIIR is 0
      
      Q: Can't we just clear DEIIR before SDEIIR?
      A: It doesn't work. SDEIIR has to be completely cleared (including the
      interrupts stored on its back queue) before it can flip DEIIR's bit to
      1 again, and even while you're clearing it you'll be getting more and
      more interrupts.
      
      Q: Why does it work by just disabling+enabling the south interrupts?
      A: Because when we re-enable them, if there's something on the SDEIIR
      register (maybe an interrupt stored on the queue), the re-enabling
      will make DEIIR's bit flip to 1, and since we'll already have
      interrupts enabled we'll get another interrupt, then run our irq
      handler again to process the "back" interrupts.
      
      v2: Even bigger commit message, added code comments.
      
      Note that this fixes missed dp aux irqs which have been reported for
      3.9-rc1. This regression has been introduced by switching to
      irq-driven dp aux transactions with

       "The biggest feature in the pull is the new (and still experimental)
        raid56 code that David Woodhouse started long ago.  I'm still working
        on the parity logging setup that will avoid inconsistent parity after
        a crash, so this is only for testing right now.  But, I'd really like
        to get it out to a broader audience to hammer out any performance
        issues or other problems.
      
        scrub does not yet correct errors on raid5/6 either.
      
        Josef has another pass at fsync performance.  The big change here is
        to combine waiting for metadata with waiting for data, which is a big
        latency win.  It is also step one toward using atomics from the
        hardware during a commit.
      
        Mark Fasheh has a new way to use btrfs send/receive to send only the
        metadata changes.  SUSE is using this to make snapper more efficient
        at finding changes between snapshosts.
      
        Snapshot-aware defrag is also included.
      
        Otherwise we have a large number of fixes and cleanups.  Eric Sandeen
        wins the award for removing the most lines, and I'm hoping we steal
