Merge tag 'drm-intel-next-2017-08-18' of git://anongit.freedesktop.org/git/drm-intel into drm-next

Browse Source 
Final pile of features for 4.14

- New ioctl to change NOA configurations, plus prep (Lionel)
- CCS (color compression) scanout support, based on the fancy new
  modifier additions (Ville&Ben)
- Document i915 register macro style (Jani)
- Many more gen10/cnl patches (Rodrigo, Pualo, ...)
- More gpu reset vs. modeset duct-tape to restore the old way.
- prep work for cnl: hpd_pin reorg (Rodrigo), support for more power
  wells (Imre), i2c pin reorg (Anusha)
- drm_syncobj support (Jason Ekstrand)
- forcewake vs gpu reset fix (Chris)
- execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris)
- switch to idr/radixtree instead of the resizing ht for execbuf id->vma
  lookups (Chris)

gvt:
- MMIO save/restore optimization (Changbin)
- Split workload scan vs. dispatch for more parallel exec (Ping)
- vGPU full 48bit ppgtt support (Joonas, Tina)
- vGPU hw id expose for perf (Zhenyu)

Bunch of work all over to make the igt CI runs more complete/stable.
Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for
progress in getting this ready. Next week we're going into production
mode (i.e. will send results to intel-gfx) on hsw, more platforms to
come.

Also, a new maintainer tram, I'm stepping out. Huge thanks to Jani for
being an awesome co-maintainer the past few years, and all the best
for Jani, Joonas&Rodrigo as the new maintainers!

/**
* DOC: The i915 register macro definition style guide
*
* Follow the style described here for new macros, and while changing existing
* macros. Do **not** mass change existing definitions just to update the style.
*
* Layout
* ''''''
*
* Keep helper macros near the top. For example, _PIPE() and friends.
*
* Prefix macros that generally should not be used outside of this file with
* underscore '_'. For example, _PIPE() and friends, single instances of
* registers that are defined solely for the use by function-like macros.
*
* Avoid using the underscore prefixed macros outside of this file. There are
* exceptions, but keep them to a minimum.
*
* There are two basic types of register definitions: Single registers and
* register groups. Register groups are registers which have two or more
* instances, for example one per pipe, port, transcoder, etc. Register groups
* should be defined using function-like macros.
*
* For single registers, define the register offset first, followed by register
* contents.
*
* For register groups, define the register instance offsets first, prefixed
* with underscore, followed by a function-like macro choosing the right
* instance based on the parameter, followed by register contents.
*
* Define the register contents (i.e. bit and bit field macros) from most
* significant to least significant bit. Indent the register content macros
* using two extra spaces between ``#define`` and the macro name.
*
* For bit fields, define a ``_MASK`` and a ``_SHIFT`` macro. Define bit field
* contents so that they are already shifted in place, and can be directly
* OR'd. For convenience, function-like macros may be used to define bit fields,
* but do note that the macros may be needed to read as well as write the
* register contents.
*
* Define bits using ``(1 << N)`` instead of ``BIT(N)``. We may change this in
* the future, but this is the prevailing style. Do **not** add ``_BIT`` suffix
* to the name.
*
* Group the register and its contents together without blank lines, separate
* from other registers and their contents with one blank line.
*
* Indent macro values from macro names using TABs. Align values vertically. Use
* braces in macro values as needed to avoid unintended precedence after macro
* substitution. Use spaces in macro values according to kernel coding
* style. Use lower case in hexadecimal values.
*
* Naming
* ''''''
*
* Try to name registers according to the specs. If the register name changes in
* the specs from platform to another, stick to the original name.
*
* Try to re-use existing register macro definitions. Only add new macros for
* new register offsets, or when the register contents have changed enough to
* warrant a full redefinition.
*
* When a register macro changes for a new platform, prefix the new macro using
* the platform acronym or generation. For example, ``SKL_`` or ``GEN8_``. The
* prefix signifies the start platform/generation using the register.
*
* When a bit (field) macro changes or gets added for a new platform, while
* retaining the existing register macro, add a platform acronym or generation
* suffix to the name. For example, ``_SKL`` or ``_GEN8``.
*
* Examples
* ''''''''
*
* (Note that the values in the example are indented using spaces instead of
* TABs to avoid misalignment in generated documentation. Use TABs in the
* definitions.)::
*
* #define _FOO_A 0xf000
* #define _FOO_B 0xf001
* #define FOO(pipe) _MMIO_PIPE(pipe, _FOO_A, _FOO_B)
* #define FOO_ENABLE (1 << 31)
* #define FOO_MODE_MASK (0xf << 16)
* #define FOO_MODE_SHIFT 16
* #define FOO_MODE_BAR (0 << 16)
* #define FOO_MODE_BAZ (1 << 16)
* #define FOO_MODE_QUX_SNB (2 << 16)
*
* #define BAR _MMIO(0xb000)
* #define GEN8_BAR _MMIO(0xb888)
