git://anongit.freedesktop.org/git/drm-intel into drm-next
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!

The pattern of a power well backing a set of fuses whose initialization
we need to wait for during power well enabling is common to all GEN9+
platforms. Adding support for this to the HSW power well enable helper
allows us to use the HSW/BDW power well code for GEN9+ as well in a
follow-up patch.
v2:
- Use an enum for power gates instead of raw numbers. (Ville)

Once the Windows guest is shutdown, the display pipe will be disabled
and intel_gvt_check_vblank_emulation will be called to check if the
vblank timer is turned off. Given the scenario of creating VM1 ,VM2,
destoying VM2 in current code, VM1 has pipe enabled and continues to
check VM2, the flag have_enabled_pipe is always false since all the VM2
pipes are disabled, so the vblank timer will be canceled and TDR happens
in Windows VM1 guest due to the vsync timeout.
In this patch the vblank timer will be never canceled once one pipe is
enabled.
v2:
- remove have_enabled_pipe flag and check pipe enabled directly. (Zhenyu)

When host connects a crt screen, linux guest will detect two
screens: crt and dp. This is wrong as linux guest has only
one dp.
In order to avoid guest get host crt screen, we should set
ADPA_CRT_HOTPLUG_MONITOR to none. But MMIO_RO(PCH_ADPA) prevent
from that. So MMIO_DH should be used instead of MMIO_RO.
v2: Clear its staus to none at initialize, so guest don't
get host crt.(Zhangyu)
v3: SKL doesn't have this register, limit it to pre_skl.(xiong)

On BDW, when host physical screen and guest virtual screen aren't on
the same DDI port, guest i915 driver prints the following error and
stop running.
[ 6.775873] BUG: unable to handle kernel NULL pointer dereference

The null pointer is guest intel_crtc_state->shared_dpll which is
setted in haswell_get_ddi_pll(). When guest and host screen are
on different DDI port, host driver won't set PORT_CLK_SET(guest_port),
so haswell_get_ddi_pll() will return null and don't set
pipe_config->shared_dpll, once the following program refernce this
structure, it will print the above error.
This patch set the initial val of guest PORT_CLK_SEL(guest_port) to
LCPLL_810. And guest i915 driver will reset this value according to
guest screen mode.

GVT implements a purely virtual monitor for virtual GPU independent of
the host. Some DDI related MMIO are not initialized in current code
which cause the display initialization failure in guest. This patch
fills the gap.

This assigns resolution definition for each vGPU type. For smaller
resource type we should limit max resolution, so e.g limit to 1024x768
for 64M type, others are still default to 1920x1200.

i915 core should only call functions and structures exposed through
intel_gvt.h. Remove internal gvt.h and i915_pvinfo.h.
Change for internal intel_gvt structure as private handler which
not requires to expose gvt internal structure for i915 core.
v2: Fix per Chris's comment
- carefully handle dev_priv->gvt assignment
- add necessary bracket for macro helper
- forward declartion struct intel_gvt
- keep free operation within same file handling alloc
v3: fix use after free and remove intel_gvt.initialized

This patch introduces the GVT-g display virtualization.
It consists a collection of display MMIO handlers, like power well register
handler, pipe register handler, plane register handler, which will emulate
all display MMIOs behavior to support virtual mode setting sequence for
