drm/i915: Introduce a gmbus power domain
gmbus also needs the power domain infrastructure right from the start,
since as soon as we register the i2c controllers someone can use them.
v2: Adjust cleanup paths too (Chris).
v3: Rebase onto -nightly (totally bogus tree I had lying around) and
also move dpio init head (Ville).
v4: Ville instead suggested to move gmbus setup later in the sequence,
since it's only needed by the modeset code.
v5: Move even close to the actual user, right next to the comment that
states where we really need gmbus (and interrupts!).

commit 2dc2f761dea65069485110d24eaa5b0d5d808b07 upstream.
This fixes reprobing of display connectors on resume. After some
talking with danvet on IRC, I learned that calling
drm_helper_hpd_irq_event() does actually trigger a full reprobe of each
connector's status. It turns out this is the actual reason reprobing on
resume hasn't been working (this was observed on a T440s):
- We call hpd_init()
- We check each connector for a couple of things before marking
connector->polled with DRM_CONNECTOR_POLL_HPD, one of which is an
active encoder. Of course, a disconnected port won't have an
active encoder, so we don't add the flag to any of the
connectors.
- We call drm_helper_hpd_irq_event()
- drm_helper_irq_event() checks each connector for the
DRM_CONNECTOR_POLL_HPD flag. The only one that has it is eDP-1,
so we skip reprobing each connector except that one.
In addition, we also now avoid setting connector->polled to
DRM_CONNECTOR_POLL_HPD for MST connectors, since their reprobing is
handled by the mst helpers. This is probably what was originally
intended to happen here.
Changes since V1:
* Use the explanation of the issue as the commit message instead
* Change the title of the commit, since this does more then just stop a
check for an encoder now
* Add "Fixes" line for the patch that introduced this regression
* Don't enable DRM_CONNECTOR_POLL_HPD for mst connectors
Changes since V2:
* Put patch changelog above Signed-off-by
* Follow Daniel Vetter's suggestion for making the code here a bit more
legible

commit 06ef83a705a98da63797a5a570220b6ca36febd4 upstream.
Following a GPU reset, we may leave the context in a poorly defined
state, and reloading from that context will leave the GPU flummoxed. For
secondary contexts, this will lead to that context being banned - but
currently it is also causing the default context to become banned,
leading to turmoil in the shared state.
This is a regression from

commit ff683df7bf34f90766a50c7e7454e219aef2710e upstream.
In the display resume path, move the calls to drm_vblank_on()
after the point when the display engine is running again.
Since changes were made to drm_update_vblank_count() in Linux 4.4+
to emulate hw vblank counters via vblank timestamping, the function
drm_vblank_on() now needs working high precision vblank timestamping
and therefore working scanout position queries at time of call.
These don't work before the display engine gets restarted, causing
miscalculation of vblank counter increments and thereby large forward
jumps in vblank count at display resume. These jumps can cause client
hangs on resume, or desktop hangs in the case of composited desktops.
Fix this Linux 4.4 regression by reordering calls accordingly.

commit e1d09dc0ccc6c91e3916476f636edb76da1f65bb upstream.
This fixes a regression introduced in Linux 4.4.
This is a port of the same fix for radeon-kms in the
patch "drm/radeon: Don't hang in radeon_flip_work_func
on disabled crtc. (v2)"
Limit the amount of time amdgpu_flip_work_func can
delay programming a page flip, by both limiting the
maximum amount of time per wait cycle and the maximum
number of wait cycles. Continue the flip if the limit
is exceeded, even if that may result in a visual or
timing glitch.
This is to prevent a hang of page flips, as reported
in fdo bug #93746: Disconnecting a DisplayPort display
in parallel to a kms pageflip getting queued can cause
the following hang of page flips and thereby an unusable
desktop:
1. kms pageflip ioctl() queues pageflip -> queues execution
of amdgpu_flip_work_func.
2. Hotunplug of display causes the driver to DPMS OFF
the unplugged display. Display engine shuts down,
scanout no longer moves, but stays at its resting
position at start line of vblank.
3. amdgpu_flip_work_func executes while crtc is off, and
due to the non-moving scanout position, the new flip
delay code introduced into Linux 4.4 by
commit 8e36f9d33c13 ("drm/amdgpu: Fixup hw vblank counter/ts..")
enters an infinite wait loop.
4. After reconnecting the display, the pageflip continues
to hang in 3. and the display doesn't update its view
of the desktop.
This patch fixes the Linux 4.4 regression from fdo bug #93746

commit 005ae95e6ec119c64e2d16eb65a94c49e1dcf9f0 upstream.
eaddr is sometimes treated as the last address inside the address
range, and sometimes as the first address outside the range. This
was resulting in errors when a test filled up the entire address
space. Make it consistent to always be the last address within the
range.

commit a50e2bf5a0f674d62b69f51f6935a30e82bd015c upstream.
When the framebuffer is a vmwgfx dma buffer and a proxy surface is
created, the vmw_kms_update_proxy() function requires that the proxy
surface width and the framebuffer pitch are compatible, otherwise
display corruption occurs as seen in gnome-shell/native with software
3D. Since the framebuffer pitch is determined by user-space, allocate
a proxy surface the width of which is based on the framebuffer pitch
rather than on the framebuffer width.
