      There seems to be an issue tracking the last flush of

      VM is used.  For now just flush the VM for every IB.

      drm: Perform ioctl command validation on the stored kernel values · e4fda9f2
      Chris Wilson authored
      Userspace is free to pass in any command bits it feels like through the
      ioctl cmd, and for example trinity likes to fuzz those bits to create
      conflicting commands. So instead of relying upon userspace to pass along
      the correct IN/OUT flags for the ioctl, use the flags as expected by the
      kernel.
      
      This does have a side-effect that NULL pointers can not be substituted
      by userspace in place of a struct. This feature was not being used by
      any driver, but instead exposed all of the command handlers to a user
      triggerable OOPS.

      The drm_mode_config_cleanup() function needs to be moved after the

      well to keep the functions together.

      For 3.10 I have a bunch of fixes queued up and I plan to send them all out
      at the end of this week. I need to shuffle patches in my -next queue a bit
      so that we don't but feature-y stuff in there, too. The main thing I'd
      like to sneak in is Egbert's hpd irq storm handling, which should be
      pretty low-risk since all the infrastructure work has landed already. I
      also have the oops fix pending, but that only mustered review before the
      w/e and giving how hairy that part of our modeset code is, I want to give
      it some more testing before forwarding.

      upstream -rc I've backmerged is already in your drm-next.

      drm/omap: Fix and improve crtc and overlay manager correlation · 0d8f371f
      Archit Taneja authored
      The omapdrm driver currently takes a config/module arg to figure out the number
      of crtcs it needs to create. We could create as many crtcs as there are overlay
      managers in the DSS hardware, but we don't do that because each crtc eats up
      one DSS overlay, and that reduces the number of planes we can attach to a single
      crtc.
      
      Since the number of crtcs may be lesser than the number of hardware overlay
      managers, we need to figure out which overlay managers to use for our crtcs. The
      current approach is to use pipe2chan(), which returns a higher numbered manager
      for the crtc.
      
      The problem with this approach is that it assumes that the overlay managers we
      choose will connect to the encoders the platform's panels are going to use,
      this isn't true, an overlay manager connects only to a few outputs/encoders, and
      choosing any overlay manager for our crtc might lead to a situation where the
      encoder cannot connect to any of the crtcs we have chosen. For example, an
      omap5-panda board has just one hdmi output. If num_crtc is set to 1, with the
      current approach, pipe2chan will pick up the LCD2 overlay manager, which cannot
      connect to the hdmi encoder at all. The only manager that could have connected
      to hdmi was the TV overlay manager.
      
      Therefore, there is a need to choose our overlay managers keeping in mind the
      panels we have on that platform. The new approach iterates through all the
      available panels, creates encoders and connectors for them, and then tries to
      get a suitable overlay manager to create a crtc which can connect to the
      encoders.
      
      We use the dispc_channel field in omap_dss_output to retrieve the desired
      overlay manager's channel number, we then check whether the manager had already
      been assigned to a crtc or not. If it was already assigned to a crtc, we assume
      that out of all the encoders which intend use this crtc, only one will run at a
      time. If the overlay manager wan't assigned to a crtc till then, we create a
      new crtc and link it with the overlay manager.
      
      This approach just looks for the best dispc_channel for each encoder. On DSS HW,
      some encoders can connect to multiple overlay managers. Since we don't try
      looking for alternate overlay managers, there is a greater possibility that 2
      or more encoders end up asking for the same crtc, causing only one encoder to
      run at a time.
      
      Also, this approach isn't the most optimal one, it can do either good or bad
      depending on the sequence in which the panels/outputs are parsed. The optimal
      way would be some sort of back tracking approach, where we improve the set of
      managers we use as we iterate through the list of panels/encoders. That's
      something left for later.

      drm/omap: Take a fb reference in omap_plane_update() · b03e14fd
      Archit Taneja authored
      When userspace calls SET_PLANE ioctl, drm core takes a reference of the fb and
      passes control to the update_plane op defined by the drm driver.
      
      In omapdrm, we have a worker thread which queues framebuffers objects received
      from update_plane and displays them at the appropriate time.
      
      It is possible that the framebuffer is destoryed by userspace between the time
      of calling the ioctl and apply-worker being scheduled. If this happens, the
      apply-worker holds a pointer to a framebuffer which is already destroyed.
      
      Take an extra refernece/unreference of the fb in omap_plane_update() to prevent
      this from happening. A reference is taken of the fb passed to update_plane(),
      the previous framebuffer (held by plane->fb) is unreferenced. This will prevent
      drm from destroying the framebuffer till the time it's unreferenced by the
      apply-worker.
      
      This is in addition to the exisitng reference/unreference in update_pin(),
      which is taken for the scanout of the plane's current framebuffer, and an
      unreference the previous framebuffer.

      drm/omap: Make fixed resolution panels work · bddabbe1
      Archit Taneja authored
      The omapdrm driver requires omapdss panel drivers to expose ops like detect,
      set_timings and check_timings. These can be NULL for fixed panel DPI, DBI, DSI
      and SDI drivers. At some places, there are no checks to see if the panel driver
      has these ops or not, and that leads to a crash.
      
      The following things are done to make fixed panels work:
      
      - The omap_connector's detect function is modified such that it considers panel
        types which are generally fixed panels as always connected(provided the panel
        driver doesn't have a detect op). Hence, the connector corresponding to these
        panels is always in a 'connected' state.
      
      - If a panel driver doesn't have a check_timings op, assume that it supports the
        mode passed to omap_connector_mode_valid(the 'mode_valid' drm helper function)
      
      - The function omap_encoder_update shouldn't really do anything for fixed
        resolution panels, make sure that it calls set_timings only if the panel
        driver has one.

      drm/omap: fix modeset_init if a panel doesn't satisfy omapdrm requirements · 581382e3
      Archit Taneja authored
      modeset_init iterates through all the registered omapdss devices and has some
      initial checks to see if the panel has a driver and the required driver ops for
      it to be usable by omapdrm.
      
      The function bails out from modeset_init if a panel doesn't meet the
      requirements, and stops the registration of the future panels and encoders which
      come after it, that isn't the correct thing to do, we should go through the rest
      of the panels. Replace the 'return's with 'continue's.

      OMAPDSS: DPI: widen the pck search when using dss fck · 2c6360fb
      Tomi Valkeinen authored
      When not using DSI PLL to generate the pixel clock, but DSS FCK, the
      possible pixel clock rates are rather limited. DSS FCK is currently used
      on OMAP2 and OMAP3.
      
      When using Beagleboard with a monitor that supports high resolutions,
      the clock rates do not match (at least for me) for the monitor's pixel
      clocks within the current threshold in the code, which is +/- 1MHz.
      
      This patch widens the search up to +/- 15MHz. The search is done in
      steps, i.e. it first tries to find a rather exact clock, than a bit less
      exact, etc. so this should not change the cases where a clock was
      already found.

      OMAPDSS: fix dss_fck clock rate rounding · 648a55e1
      Tomi Valkeinen authored
      DSS func clock is calculated with prate / div * m. However, the current
      omapdss code calculates it with prate * m / div, which yields a slightly
      different result when there's a remainder. For example, 432000000 / 14 *
      2 = 61714284, but 432000000 * 2 / 14 = 61714285.
      
      In addition to that, the clock framework wants the clock rate given with
      clk_set_rate to be higher than the actual (truncated) end result. So, if
      prate is 432000000, and div is 14, the real result is 30857142.8571...
      We need to call clk_set_rate with 30857143, which gives us a clock of
      30857142. That's why we need to use DIV_ROUND_UP() when calling
      clk_set_rate.
      
      This patch fixes the clock calculation.

      gma500:fix build failure for 3.9-rc5 · 0c1a14c2
      Xiong Zhou authored
      Last version of this patch is not clear enough and X86 duplicated.
      
      This patch fixes build failure of v3.9-rc5 and rc6.
      When config ACPI_VIDEO as m, DRM_GMA500 as y, here comes the failure.
      GMA5/600 needs acpi_video just like nouveau.
      And some tab type fix by the way.
      
      Failure message:
      drivers/built-in.o: In function `psb_driver_load':
      kernel-3.9-rc5/drivers/gpu/drm/gma500/psb_drv.c:340: \
      	undefined reference to `acpi_video_register'
