Merge branch 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux into drm-next

A couple of fixes from the previous pull request as well as gl3 support.
There is one drm core change, an export of a previously private function.

Take 2 implementing screen targets, this time with the fbdev code adjusted
accordingly.

Also there is an implementation of register-driven command buffers, that
overrides the FIFO ring for command processing. It's needed for our upcoming
hardware revision.

+ * The metadata for each command buffer is contained in the

+ *
+ * The SVGA device supports command buffers if
+ * SVGA_CAP_COMMAND_BUFFERS is set in the device caps register.  The
+ * fifo must be enabled for command buffers to be submitted.
+ *
+ * Command buffers are submitted when the guest writing the 64 byte
+ * aligned physical address into the SVGA_REG_COMMAND_LOW and
+ * SVGA_REG_COMMAND_HIGH.  SVGA_REG_COMMAND_HIGH contains the upper 32
+ * bits of the physical address.  SVGA_REG_COMMAND_LOW contains the
+ * lower 32 bits of the physical address, since the command buffer
+ * headers are required to be 64 byte aligned the lower 6 bits are
+ * used for the SVGACBContext value.  Writing to SVGA_REG_COMMAND_LOW
+ * submits the command buffer to the device and queues it for
+ * execution.  The SVGA device supports at least
+ * SVGA_CB_MAX_QUEUED_PER_CONTEXT command buffers that can be queued
+ * per context and if that limit is reached the device will write the
+ * status SVGA_CB_STATUS_QUEUE_FULL to the status value of the command
+ * buffer header synchronously and not raise any IRQs.
+ *
+ * It is invalid to submit a command buffer without a valid physical
+ * address and results are undefined.
+ *
+ * The device guarantees that command buffers of size SVGA_CB_MAX_SIZE
+ * will be supported.  If a larger command buffer is submitted results
+ * are unspecified and the device will either complete the command
+ * buffer or return an error.
+ *
+ * The device guarantees that any individual command in a command
+ * buffer can be up to SVGA_CB_MAX_COMMAND_SIZE in size which is
+ * enough to fit a 64x64 color-cursor definition.  If the command is
+ * too large the device is allowed to process the command or return an
+ * error.
+ *
+ * The device context is a special SVGACBContext that allows for
+ * synchronous register like accesses with the flexibility of
+ * commands.  There is a different command set defined by
+ * SVGADeviceContextCmdId.  The commands in each command buffer is not
+ * allowed to straddle physical pages.

- *
- *    This clipping region serves multiple purposes:

- *      - It can be used to perform an irregularly shaped blit more
- *        efficiently than by issuing many separate blit commands.
- *
- *      - It is equivalent to allowing blits with non-integer

- *      these formats natively, the SVGA3D device will provide an emulation
- *      which should be invisible to the guest OS.
- *
- *      In general, the SVGA3D device should support any operation on
- *      any surface format, it just may perform some of these
- *      operations in software depending on the capabilities of the
- *      available physical hardware.
- *
- *      XXX: In the future, we will add capabilities that describe in

- * enum svga3d_block_desc describes the active data channels in a block.
- *
- * There can be at-most four active channels in a block:
- *    1. Red, bump W, luminance and depth are stored in the first channel.
- *    2. Green, bump V and stencil are stored in the second channel.
- *    3. Blue and bump U are stored in the third channel.
- *    4. Alpha and bump Q are stored in the fourth channel.
- *
- * Block channels can be used to store compressed and buffer data:
- *    1. For compressed formats, only the data channel is used and its size
- *       is equal to that of a singular block in the compression scheme.
- *    2. For buffer formats, only the data channel is used and its size is
- *       exactly one byte in length.
- *    3. In each case the bit depth represent the size of a singular block.
- *
- * Note: Compressed and IEEE formats do not use the bitMask structure.

+/*
+ * This file implements the vmwgfx context binding manager,
+ * The sole reason for having to use this code is that vmware guest
+ * backed contexts can be swapped out to their backing mobs by the device
+ * at any time, also swapped in at any time. At swapin time, the device
+ * validates the context bindings to make sure they point to valid resources.
+ * It's this outside-of-drawcall validation (that can happen at any time),
+ * that makes this code necessary.
+ *
+ * We therefore need to kill any context bindings pointing to a resource
+ * when the resource is swapped out. Furthermore, if the vmwgfx driver has
+ * swapped out the context we can't swap it in again to kill bindings because
+ * of backing mob reservation lockdep violations, so as part of
+ * context swapout, also kill all bindings of a context, so that they are
+ * already killed if a resource to which a binding points
+ * needs to be swapped out.
+ *
+ * Note that a resource can be pointed to by bindings from multiple contexts,
+ * Therefore we can't easily protect this data by a per context mutex
+ * (unless we use deadlock-safe WW mutexes). So we use a global binding_mutex
+ * to protect all binding manager data.
+ *
+ * Finally, any association between a context and a global resource
+ * (surface, shader or even DX query) is conceptually a context binding that
+ * needs to be tracked by this code.
