Subject: drm/i915: add HAS_ALIASING_PPGTT parameter for userspace

On Sanybridge a few MI read/write commands only work when ppgtt is
enabled.  Userspace therefore needs to be able to check whether ppgtt
is enabled. For added hilarity, you need to reset the "use global GTT"
bit on snb when ppgtt is enabled, otherwise it won't work.  Despite
what bspec says about automatically using ppgtt ...

Luckily PIPE_CONTROL (the only write cmd current userspace uses) is
not affected by all this, as tested by tests/gem_pipe_control_store_loop.

For -stable because the next patch (fixing phys obj pwrite) needs this

Subject: mm: extend prefault helpers to fault in more than PAGE_SIZE

drm/i915 wants to read/write more than one page in its fastpath
and hence needs to prefault more than PAGE_SIZE bytes.

Add new functions in filemap.h to make that possible.

Also kill a copy&pasted spurious space in both functions while at it.

v2: As suggested by Andrew Morton, add a multipage parameter to both
functions to avoid the additional branch for the pagemap.c hotpath.
My gcc 4.6 here seems to dtrt and indeed reap these branches where not
needed.

v3: Becaus I couldn't find a way around adding a uaddr += PAGE_SIZE to
the filemap.c hotpaths (that the compiler couldn't remove again),
let's go with separate new functions for the multipage use-case.

v4: Adjust comment to CodingStlye and fix spelling.

Subject: drm/edid: Allow drm_mode_find_dmt to hunt for reduced-blanking modes

It won't find any, yet.  Fix up callers to match: standard mode codes
will look prefer r-b modes for a given size if present, EST3 mode codes
will look for exactly the r-b-ness mentioned in the mode code.  This
might mean fewer modes matched for EST3 mode codes between now and when
the DMT mode list regrows the r-b modes, but practically speaking EST3
codes don't exist in the wild.

Requiring the first byte of the EDID base block header to be 0 means we
don't fix up as many transfer errors as we could.  Instead have the
callers specify whether it's meant to be block 0 or not, and
conditionally run header fixup based on that.

Subject: drm: pass dev to drm_vm_{open,close}_locked()

Previously these functions would assume that vma->vm_file was the
drm_file.  Although if in some cases if the drm driver needs to use
something else for the backing file (such as the tmpfs filp) then this
assumption is no longer true.  But vma->vm_private_data is still the
GEM object.

With this change, now the drm_device comes from the GEM object rather
than the drm_file so the driver is more free to play with vma->vm_file.

The scenario where this comes up is for mmap'ing of cached dmabuf's
for non-coherent systems, where the driver needs to use fault handling
and PTE shootdown to simulate coherency.  We can't use the vma->vm_file
of the dmabuf, which is using anon_inode's address_space.  The most
straightforward thing to do is to use the GEM object's obj->filp for
vma->vm_file in all cases, for which we need this patch.

This changes the API as a clean-up.  Instead of passing multiple

whole callback functions and pass it to the registration.

The same struct will be used for the upcoming audio client
registration, too.

Subject: drm: WARN() when drm_connector_attach_property fails

Also return void instead of int. We have more than 100 callers and
no one checks for the return value.

If this function fails the property won't be exposed by the get/set
ioctls, but we should probably survive. If this starts happening,
the solution will be to increase DRM_CONNECTOR_MAX_PROPERTY and
recompile the Kernel.

For now, only connectors have it. In the future, all objects that need
properties should use it. Since the structure is referenced inside
struct drm_mode_object, we will be able to deal with object properties
without knowing the real type of the object.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This way, we don't need to count every time, so we're a little bit
faster and code is a little bit smaller.

Change suggested by Ville Syrjälä.

Subject: drm/exynos: add G2D driver

Changelog v3:
- use __u64 instead of pointer in ioctl struct.

The G2D is a 2D graphic accelerator that supports Bit Block Transfer.
This G2D driver is exynos drm specific and supports only G2D(version
4.1) of later Exynos series from Exynos4X12 because supporting DMA.

The G2D is performed by two tasks simply.
1. Configures the rendering parameters, such as foreground color and
   coordinates data by setting the drawing context registers.
2. Start the rendering process by setting thre relevant command
   registers accordingly.

The G2D version 4.1 supports DMA mode as host interface. User can make
command list to reduce HOST(ARM) loads. The contents of The command list
is setted to relevant registers of G2D by DMA.

The command list is composed Header and command sets and Tail.
- Header: The number of command set(4Bytes)
- Command set: Register offset(4Bytes) + Register data(4Bytes)
- Tail: Pointer of base address of the other command list(4Bytes)

By Tail field, the G2D can process many command lists without halt at
one go.

The G2D has following the rendering pipeline.
--> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling
--> Color Key --> ROP --> Mask Operation --> Alpha Blending -->
Dithering --> FrameBuffer

And supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- window clipping
- rotation
- flip
- 4 operand raster operation(ROP4)
- masking operation
- alpha blending
- color key
- dithering
- etc

User should make the command list to data and registers needed by
operation to use. The Exynos G2D driver only manages the command lists
received from user. Some registers needs memory base address(physical
address) of image. User doesn't know its physical address, so fills the
gem handle of that memory than address to command sets, then G2D driver
converts it to memory base address.

We adds three ioctls and one event for Exynos G2D.

- ioctls
DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version
DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver
DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver

- event
DRM_EXYNOS_G2D_EVENT: event to give notification completion of the
		      command list to user

This lets the kernel tell userspace if the device supports prime

This is useful for -modesetting at least, but would be nice for other

Subject: drm: Constify gem_vm_ops pointer

The GEM vm operations structure is passed to the VM core that stores it
in a const field. There vm operations structures can thus be const in
DRM as well.

A bitmask property is similar to an enum.  The enum value is a bit
position (0-63), and valid property values consist of a mask of
zero or more of (1 << enum_val[n]).

The omapdrm driver uses this for setting per-overlay rotation.  It
is likely also useful for setting YUV->RGB colorspace conversion
matrix, etc.

Subject: drm/prime: introduce sg->pages/addr arrays helper

the ttm drivers need this currently, in order to get fault handling
working and efficient.

It also allows addrs to be NULL for devices like udl.

Subject: ttm: add prime sharing support to TTM (v2)

This adds the ability for ttm common code to take an SG table
and use it as the backing for a slave TTM object.

The drivers can then populate their GTT tables using the SG object.

v2: make sure to setup VM for sg bos as well.
