drm/i915: Flush ggtt writes through the old fenced vma before changing fences
This is a precautionary measure as I have no evidence to suggest we've
hit a bug here (I was hoping this might explain gdg's odd behaviour, but
alas), but given that we have a function to flush the ggtt writes it
seems prudent to use it prior to changing the fence register. Due to the
intrinsic nature of the GTT often operating as an independent mmio path,
we should not just rely on the write to the fence acting as a full flush
for GTT writes.

drm/i915: Always run hangcheck while the GPU is busy
Previously, we relied on only running the hangcheck while somebody was
waiting on the GPU, in order to minimise the amount of time hangcheck
had to run. (If nobody was watching the GPU, nobody would notice if the
GPU wasn't responding -- eventually somebody would care and so kick
hangcheck into action.) However, this falls apart from around commit
4680816be336 ("drm/i915: Wait first for submission, before waiting for
request completion"), as not all waiters declare themselves to hangcheck
and so we could switch off hangcheck and miss GPU hangs even when
waiting under the struct_mutex.
If we enable hangcheck from the first request submission, and let it run
until the GPU is idle again, we forgo all the complexity involved with
only enabling around waiters. We just have to remember to be careful that
we do not declare a GPU hang when idly waiting for the next request to
be come ready, as we will run hangcheck continuously even when the
engines are stalled waiting for external events. This should be true
already as we should only be tracking requests submitted to hardware for
execution as an indicator that the engine is busy.

CTX_CONTEXT_CONTROL (CTX_SR_CTL) operates as a masked register and so
will only apply the bits that are selected by the upper half. In the
case of selectively enabling sr inhibit, this may mean the context keeps
the current setting (so forgetting to save the context later, eventually
leading to a very upset GPU!).

drm/i915/guc: Fix lockdep due to log relay channel handling under struct_mutex
This patch fixes lockdep issue due to circular locking dependency of
struct_mutex, i_mutex_key, mmap_sem, relay_channels_mutex.
For GuC log relay channel we create debugfs file that requires i_mutex_key
lock and we are doing that under struct_mutex. So we introduced newer
dependency as:
&dev->struct_mutex --> &sb->s_type->i_mutex_key#3 --> &mm->mmap_sem
However, there is dependency from mmap_sem to struct_mutex. Hence we
separate the relay create/destroy operation from under struct_mutex.
Also added runtime check of relay buffer status.

drm/i915: Increase render/media power gating hysteresis for gen9+
On gen9+, after an idle period the HW will disable the entire power well
to conserve power (by preventing current leakage). It takes around a 100
microseconds to bring the power well back online afterwards. With the
current hysteresis value of 25us (really 25 * 1280ns), we do not have
sufficient time to respond to an interrupt and schedule the next execution
before the HW powers itself down. (At present, we prevent this by
grabbing the forcewake for prolonged periods of time, but that overkill
fixed in the next patch.) The minimum we want to set the power gating
hysteresis to is the length of time it takes us to service the GPU, which
across a broad spectrum of machines is about 250us.
(Note this also brings guc latency into the same ballpark as execlists.)

drm/i915/edp: Do not do link training fallback or prune modes on EDP
In case of eDP because the panel has a fixed mode, the link rate
and lane count at which it is trained corresponds to the link BW
required to support the native resolution of the panel. In case of
panles with lower resolutions where fewer lanes are hooked up internally,
that number is reflected in the MAX_LANE_COUNT DPCD register of the panel.
So it is pointless to fallback to lower link rate/lane count in case
of link training failure on eDP connector since the lower link BW
will not support the native resolution of the panel and we cannot
prune the preferred mode on the eDP connector.
In case of Link training failure on the eDP panel, something is wrong
in the HW internally and hence driver errors out with a loud
and clear DRM_ERROR message.

properly on boxes with DP++ (dual-mode) adaptors. The reason for

intel_hdmi_mode_valid returns CLOCK_HIGH because the pixel clock

drm/i915: Avoid waitboosting on the active request
Watching a light workload on Baytrail (running glxgears and a 1080p
decode), instead of the system remaining at low frequency, the glxgears
would regularly trigger waitboosting after which it would have to spend
a few seconds throttling back down. In this case, the waitboosting is
counter productive as the minimal wait for glxgears doesn't prevent it
from functioning correctly and delivering frames on time. In this case,
glxgears happens to almost always be waiting on the current request,
which we already expect to complete quickly (see i915_spin_request) and
so avoiding the waitboost on the active request and spinning instead
provides the best latency without overcommitting to upclocking.
However, if the system falls behind we still force the waitboost.
Similarly, we will also trigger upclocking if we detect the system is
not delivering frames on time - again using a mechanism that tries to
detect a miss and not preemptively upclock.
v2: Also skip boosting for after missed vblank if the desired request is
already active.

v2: Use wait_event_timeout to provide an upper bound
v3: Fix inverted check for wait_event_timeout timing out
v4: Restore the check that the fences aren't signalled too early, by
inspecting them before the expected timeout.

drm/i915: Do not WARN_ON with small framebuffers.
It's perfectly legal to create a fb with stride < 512, and one of
the kms_plane_scaling subtests creates a very small fb.
Downgrade the WARN_ON to a simple check check, and because this
function is potentially called on every atomic update/pageflip,
downgrade the other WARN_ON to a WARN_ON_ONCE, and do the right
thing here.

drm: Fix PANEL_ORIENTATION_QUIRKS breaking the Kconfig DRM menuconfig
All Kconfig menu menu entries should have a depends on MENU_OPTION, the
menu stops after the first Kconfig entry without this depends on.
Since the PANEL_ORIENTATION_QUIRKS option is also used outside of DRM,
it deliberately does not have a depends on DRM, but this causes all
items after it to show as separate items rather then under the DRM
menuconfig.
This commit moves PANEL_ORIENTATION_QUIRKS to the end of the drm Kconfig
file, grouping it with DRM_LIB_RANDOM which also does not depend on DRM,
fixing the DRM menuconfig.

drm/radeon: fill in rb backend map on evergreen/ni.
This looks to have never gotten filled in, and it seems to
trigger a bug in mesa.
