The drm_mm range manager claimed to support top-down insertion, but it
was neither searching for the top-most hole that could fit the
allocation request nor fitting the request to the hole correctly.
In order to search the range efficiently, we create a secondary index
for the holes using either their size or their address. This index
allows us to find the smallest hole or the hole at the bottom or top of
the range efficiently, whilst keeping the hole stack to rapidly service
evictions.
v2: Search for holes both high and low. Rename flags to mode.
v3: Discover rb_entry_safe() and use it!
v4: Kerneldoc for enum drm_mm_insert_mode.

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

HDMI 2.0 recommends that we set the Q bits in the AVI infoframe
even when the sink does not support quantization range selection (QS=0).
According to CEA-861 we can do that as long as the Q we send matches
the default quantization range for the mode.
Previously I think I had misread the spec as saying that you can't
send a non-zero Q at all when QS=0. But that's not what the spec
actually says.

Pull the logic to populate the quantization range information
in the AVI infoframe into a small helper. We'll be adding a bit
more logic to it, and having it in a central place seems like a
good idea since it's based on the CEA-861 spec.

struct drm_dp_mst_topology_mgr currently stores a pointer to struct dev.
Changing this to instead hold a pointer to drm_device is more useful as it
gives access to DRM structures. This also makes it consistent with other
DRM structures like drm_crtc, drm_connector etc.

Updated pull request after I pulled first time :)

drm/i915: Pevent copying uninitialised garbage into vma->ggtt_view
|
| | | |

Since tweaking i915_vma_compare() we allowed constructors to skip
clearing the ggtt_view believing that we didn't access the unused
members. That, as it turns out, was not entirely true. In particular,
i915_gem_fault() uses
ret = remap_io_mapping(area,
area->vm_start + (vma->ggtt_view.partial.offset << PAGE_SHIFT),
(ggtt->mappable_base + vma->node.start) >> PAGE_SHIFT,
min_t(u64, vma->size, area->vm_end - area->vm_start),
&ggtt->mappable);
i.e. the ggtt_view.partial for both normal and partial views. If we
allowed garbage into the normal vma->ggtt_view and then try userspace
tried to mmap it, we could explode in an unobvious fashion.
Fixes: 7b92c047bae2 ("drm/i915: Eliminate superfluous i915_ggtt_view_rotated")
Fixes: 3bf4d5751943 ("drm/i915: Stop clearing i915_ggtt_view")

max/min
When we reach the user's RPS limits, stop requesting an adjustment. Even
though we will clamp the requested frequency later, we rely on interrupt
masking to disable further adjustments in the same direction. Even
though it is unlikely (one scenario is a bug in the driver, another is
careful manipulation through the uAPI) if we keep exponentially
increasing the adjustment value, it will wrap and cause a negative
adjustment.

With the introduce of i915_vma_instance() for obtaining the VMA
singleton for a (obj, vm, view) tuple, we can remove the
i915_vma_create() in favour of a single entry point. We do incur a
lookup onto an empty tree, but the i915_vma_create() were being called
infrequently and during initialisation, so the small overhead is
negligible.

light, such as i915_gem_obj_lookup_or_create(). Joonas suggested
i915_vma_instance() as a neat replacement, so rename them, move them to
i915_vma.c and add some kerneldoc as a sugary bonus.

lookups in between.

This patch will allow for getparams to return the status of the HuC.
As the HuC has to be validated by the GuC this patch uses the validated
status to show when the HuC is loaded and ready for use. You cannot use
the loaded status as with the GuC as the HuC is verified after it is
loaded and is not usable until it is verified.
v2: removed the forewakes as the registers are already force-woken.
(T.Ursulin)
v3: rebased on top of drm-tip. Removed any reference to intel_huc.h
v4: rebased. Rename I915_PARAM_HAS_HUC to I915_PARAM_HUC_STATUS.
Remove intel_is_huc_valid() since it is used only in one place.
Put the case of I915_PARAM_HAS_HUC() in the right place.
v5: rebased. Add a comment to specify that I915_READ(reg)
does not read garbage value. The register HUC_STATUS2 is force
woken and no rpm is needed.

The HuC loading process is similar to GuC. The intel_uc_fw_fetch()
is used for both cases.
HuC loading needs to be before GuC loading. The WOPCM setting must
be done early before loading any of them.
v2: rebased on-top of drm-intel-nightly.
removed if(HAS_GUC()) before the guc call. (D.Gordon)
update huc_version number of format.
v3: rebased to drm-intel-nightly, changed the file name format to
match the one in the huc package.
Changed dev->dev_private to to_i915()
v4: moved function back to where it was.
change wait_for_atomic to wait_for.
v5: rebased. Changed the year in the copyright message to reflect
the right year.Correct the comments,remove the unwanted WARN message,
replace drm_gem_object_unreference() with i915_gem_object_put().Make the
prototypes in intel_huc.h non-extern.
v6: rebased. Update the file construction done by HuC. It is similar to
GuC.Adopted the approach used in-
https://patchwork.freedesktop.org/patch/104355/ <Tvrtko Ursulin>
v7: Change dev to dev_priv in macro definition.
Corrected comments.
v8: rebased on top of drm-tip. Updated functions intel_huc_load(),
intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of
dev. Moved contents of intel_huc.h to intel_uc.h.
v9: change SKL_FW_ to SKL_HUC_FW_. Add intel_ prefix to guc_wopcm_size().
Remove unwanted checks in intel_uc.h. Rename huc_fw in struct intel_huc to
simply fw to avoid redundency.
v10: rebased. Correct comments. Make intel_huc_fini() accept dev_priv
instead of dev like intel_huc_init() and intel_huc_load().Move definition
to i915_guc_reg.h from intel_uc.h. Clean DMA_CTRL bits after HuC DMA
transfer in huc_ucode_xfer() instead of guc_ucode_xfer(). Add suitable
WARNs to give extra info.
v11: rebased. Add proper bias for HuC and make sure there are
asserts on failure by using guc_ggtt_offset_vma(). Introduce
intel_huc.c and remove intel_huc_loader.c since it has functions that
do more than just loading.Correct year in copyright.
v12: remove invalidates that are not required anymore.

Since we now only skip banned contexts, preventing the skip of default
contexts is no longer sensible. For a similar argument as before
'commit 7ec73b7e36d0 ("drm/i915: Only skip requests once a context is banned")'
we end up with an inconsistent API if we only mark future execbufs from
the default ctx as banned but fail to mark those currently executing
as failed.

Add a new function for skipping all pending requests
for a context in order to make engine reset flow more
readable.

Now that we have prepare/finish routines for the GEM reset, move the
disabling of the engine->irq_tasklet into them to reduce repetition. The
device irq enable/disable is split out to ensure it is run first and
last always (even if the GPU reset fails).
