03edf1b31a drm/nouveau/imem/nv50: support eviction of BAR2 mappings
A good deal of the structures we map into here aren't accessed very often
at all, and Fedora 26 has exposed an issue where after creating a heap of
channels, BAR2 space would run out, and we'd need to make use of the slow
path while accessing important structures like page tables.

This implements an LRU on BAR2 space, which allows eviction of mappings
that aren't currently needed, to make space for other objects.

69b136f200 drm/nouveau/imem/nv50: prevent fast-path for mapped objects when BAR isn't ready
Another piece of solving the "GP100 BAR2 VMM bootstrap" puzzle.

Without doing this, we'd attempt to write PDEs for the lower page table
levels through BAR2 before BAR2 access has been fully initialised.

be55287aa5 drm/nouveau/imem/nv50: embed nvkm_instobj directly into nv04_instobj
This is not as simple as it was for earlier GPUs, due to the need to swap
accessor functions depending on whether BAR2 is usable or not.

We were previously protected by nvkm_instobj's accessor functions keeping
an object mapped permanently, with some unclear magic that managed to hit
the slow-path where needed even if an object was marked as mapped.

That's been replaced here by reference counting maps (some objects, like
page tables can be accessed concurrently), and swapping the functions as
necessary.

af515ec8d3 drm/nouveau/imem/nv50: move slow-path locking into rd/wr functions
This is to simplify upcoming changes.  The slow-path is something that
currently occurs during bootstrap of the BAR2 VMM, while backing up an
object during suspend/resume, or when BAR2 address space runs out.

The latter is a real problem that can happen at runtime, and occurs in
Fedora 26 already (due to some change that causes a lot of channels to
be created at login), so ideally we'd prefer not to make it any slower.

We'd also like suspend/resume speed to not suffer.

Upcoming commits will solve those problems in a better way, making the
extra overhead of moving the locking here a non-issue.

bb7e501a66 drm/nouveau/bar: prevent BAR2 mapping of objects during destructor
GP100's page table nests a lot more deeply than the GF100-compatible
layout we're currently using, which means our hackish-but-simple way
of dealing with BAR2 VMM teardown won't work anymore.

In order to sanely handle the chicken-and-egg (BAR2's PTs get mapped
into themselves) problem, we need prevent page tables getting mapped
back into BAR2 during the destruction of its VMM.

To do this, we simply key off the state that's now maintained by the
BAR2 init/fini functions.

9a6edc3ac9 drm/nouveau/kms/nv04-nv40: improve overlay error detection, fix pitch setting
We were previously setting the pitch based on a perfectly packed buffer.
This does not necessarily happen. Either modetest started generating
such buffers recently, or earlier testing only happened with well-picked
overlay sizes.

While we're at it, beef up and refactor the error state detection.

3ce72bcf33 drm/nouveau/kms/nv04-nv40: prevent undisplayable framebuffers from creation
Pre-nv50 YUV overlays have stringent requirements for working with the
internal machinery. Instead of rejecting these at update_plane time, we
should instead prevent the framebuffers from being created in the first
place.

2659b4ce28 initial support (display-only) for GP108
Forked from GP107 implementation. Secboot/gr left out as we don't have
signed blobs from NVIDIA in linux-firmware.

(Ben): Was unable to mmiotrace the binary driver for unknown reasons,
       so not able to 100% confirm that no other changes from GP107
       are needed.  Quick testing shows it seems to work well enough
       for display.  Due to NVIDIA dragging their heels on getting
       signed firmware to us, this is the best we can do for now.

efa479352f drm/nouveau: Fix merge commit
The most recent merge commit in airlied/drm-next has problems with
confusing old_crtc_state and new_crtc_state. Use the
for_each_oldnew_crtc_in_state macros to clean up the confusion,
and explicitly look at the correct state instead of looking at
asyh->state.

With these fixes it becomes more obvious what the code is trying to do,
which will hopefully prevent future confusion.

38bcb208f6 drm/nouveau/bar/gf100: fix access to upper half of BAR2
Bit 30 being set causes the upper half of BAR2 to stay in physical mode,
mapped over the end of VRAM, even when the rest of the BAR has been set
to virtual mode.

We inherited our initial value from RM, but I'm not aware of any reason
we need to keep it that way.

This fixes severe GPU hang/lockup issues revealed by Wayland on F26.

0c1f528cb1 drm: handle HDMI 2.0 VICs in AVI info-frames
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).

This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.

This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.

In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
	- VIC for 4K modes for HDMI 1.4 sinks
	- S3D information for S3D modes
  As CEA-861-F has already defined VICs for 4K videomodes, this
  patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
  until the mode is 3D.

0d93cd92bd drm/nouveau/disp/nv50-: implement a common supervisor 3.0
This makes use of all the additional routing and state added in previous
commits, making it possible to deal with GM20x macro link routing, while
also sharing code between the NV50 and GF119 implementations.

6c22ea3747 drm/nouveau/disp: introduce acquire/release display path methods
These exist to give NVKM information on the set of display paths that
the DD needs to be active at any given time.

Previously, the supervisor attempted to determine this solely from OR
state, but there's a few configurations where this information on its
own isn't enough to determine the specific display paths in question:

- ANX9805, where the PIOR protocol for both DP and TMDS is TMDS.
- On a device using DCB Switched Outputs.
- On GM20x and newer, with a crossbar between the SOR and macro links.

After this commit, the DD tells NVKM *exactly* which display path it's
attempting a modeset on.
