      drm: store the gem vma offset manager in a typed pointer · b04a5906
      Daniel Vetter authored
      This was hidden in a generic void * dev->mm_private. But only ever
      used for gem. But thanks to this fake generic pretension no one
      noticed that Rob's drm drivers are now all broken.
      
      So just give the offset manager a type pointer and fix up msm, omapdrm
      and tilcdc.
      
      v2: Fixup compile fail.
      
      v3: Fixup rebase fail that David spotted.

      Anyway, nothing big here, Three more code cleanup patches from Rashika
      Kheria, and one TTM/vmwgfx patch from me that tightens security around TTM
      objects enough for them to opened using prime objects from render nodes:
      
      Previously any client could access a shared buffer using the "name", also
      without actually opening it. Now a reference is required, and for render nodes
      such a reference is intended to only be obtainable using a prime fd.

      Some code cleanup by Rashika Keria,
      VM stuff for ttm:
      -Use PFNMAP instead of MIXEDMAP where possible for performance
      -Refuse to fault imported pages, an initial step to support dma-bufs
      better from within TTM.
      -Correctly set page mapping and -index members. These are needed in various
      places in the vm subsystem that we are not using yet, but plan to use soonish:
      For example unmap-mapping-range keeping COW pages, and dirty tracking
      fbdefio style, but also for PCI memory.

      reliable than soft reset in certain cases.  Disabled by default.  Enable
      with the hard_reset module option.

      drm/msm: add a330/apq8x74 · 55459968
      Rob Clark authored
      Add support for adreno 330.  Not too much different, just a few
      differences in initial configuration plus setting OCMEM base.
      Userspace support is already in upstream mesa.
      
      Note that the existing DT code is simply using the bindings from
      downstream android kernel, to simplify porting of this driver to
      existing devices.  These do not constitute any committed/stable
      DT ABI.  The addition of proper DT bindings will be a subsequent
      patch, at which point (as best as possible) I will try to support
      either upstream bindings or what is found in downstream android
      kernel, so that existing device DT files can be used.

      drm/msm: add mdp5/apq8x74 · 06c0dd96
      Rob Clark authored
      Add support for the new MDP5 display controller block.  The mapping
      between parts of the display controller and KMS is:
      
        plane   -> PIPE{RGBn,VIGn}             \
        crtc    -> LM (layer mixer)            |-> MDP "device"
        encoder -> INTF                        /
        connector -> HDMI/DSI/eDP/etc          --> other device(s)
      
      Unlike MDP4, it appears we can get by with a single encoder, rather
      than needing a different implementation for DTV, DSI, etc.  (Ie. the
      register interface is same, just different bases.)
      
      Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
      routed through MDP.
      
      And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
      which blocks need to be allocated to the active pipes based on fetch
      stride.

      drm/msm: add hdmi support for apq8x74/mdp5 · dada25bd
      Rob Clark authored
      The HDMI block is basically the same between older SoC's with mdp4
      display controller, and newer ones with mdp5.
      
      So mostly this consists of better abstracting out the different sets of
      regulators, clks, etc.  In particular, for regulators and clks we can
      split it up by what is needed for hot plug detect to work, and what is
      needed to light up the display.
      
      Also, 8x74 has a new phy.. a very simple one, but split out into a
      different mmio space.  And with mdp5, the irq is shared with mdp, so we
      don't directly register our own irq handler.

      drm/msm: move irq utils to mdp_kms · 9e0efa63

      We'll want basically the same thing for mdp5, so refactor it out so it
      can be shared.

      This can be shared between mdp4 and mdp5.  Both use the same set of
      parameters to describe the format to the hw.

      drm/msm: move mdp4 -> mdp/mdp4 · 2e54a92f
      Rob Clark authored
      There are some little bits and pieces that mdp4 and mdp5 can share, so
      move things around so that we can have both in a common parent
      directory.

      drm/msm: add support for non-IOMMU systems · 871d812a
      Rob Clark authored
      Add a VRAM carveout that is used for systems which do not have an IOMMU.
      
      The VRAM carveout uses CMA.  The arch code must setup a CMA pool for the
      device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not
      cool).  The user can configure the VRAM pool size using msm.vram module
      param.
      
      Technically, the abstraction of IOMMU behind msm_mmu is not strictly
      needed, but it simplifies the GEM code a bit, and will be useful later
      when I add support for a2xx devices with GPUMMU, so I decided to keep
      this part.
      
      It appears to be possible to configure the GPU to restrict access to
      addresses within the VRAM pool, but this is not done yet.  So for now
      the GPU will refuse to load if there is no sort of mmu.  Once address
      based limits are supported and tested to confirm that we aren't giving
      the GPU access to arbitrary memory, this restriction can be lifted
