Upon a GPU reset, we copy the default context image over top of the

drm/i915/gem: Split eb_vma into its own allocation
Use a separate array allocation for the execbuf vma, so that we can
track their lifetime independently from the copy of the user arguments.
With luck, this has a secondary benefit of splitting the malloc size to
within reason and avoid vmalloc. The downside is that we might require
two separate vmallocs -- but much less likely.
In the process, this prevents a memory leak on the ww_mutex error
unwind.

We wish that the scheduler emit the context modification commands prior
to enabling the oa_config, for which we must explicitly inform it of the
ordering constraints. This is especially important as we now wait for
the final oa_config setup to be completed and as this wait may be on a
distinct context to the state modifications, we need that command packet

We borrow the i915_active for its ability to track multiple timelines
and the last dma_fence on each; a flexible dma_resv. Keeping track of
each dma_fence is important for us so that we can efficiently schedule
the requests and reprioritise as required.

drm/i915/execlists: Workaround switching back to a completed context

idle context with HEAD==TAIL, it appears we must prevent the HW from
switching to an idle context in ELSP[1], while simultaneously trying to
preempt the HW to run another context and a continuation of the idle
context (which is no longer idle).
We can achieve this by preventing the context from completing while we
reload a new ELSP (by applying ring_set_paused(1) across the whole of
dequeue), except this eventually fails due to a lite-restore into a
waiting semaphore does not generate an ACK. Instead, we try to avoid
making the GPU do anything too challenging and not submit a new ELSP
while the interrupts + CSB events appear to have fallen behind the
completed contexts. We expect it to catch up shortly so we queue another
tasklet execution and hope for the best.

drm/i915/debugfs: move uC printers and update debugfs file names
Move the printers to the respective files for clarity. The
guc_load_status debugfs has been squashed in the guc_info one, has
having separate ones wasn't very useful. The HuC debugfs has been
renamed huc_info to match.

drm/i915/huc: make "support huc" reflect HW capabilities
We currently initialize HuC support based on GuC being enabled in
modparam; this means that huc_is_supported() can return false on HW that
does have a HuC when enable_guc=0. The rationale for this behavior is
that HuC requires GuC for authentication and therefore is not supported
by itself. However, we do not allow defining HuC fw wthout GuC fw and
selecting HuC in modparam implicitly selects GuC as well, so we can't
actually hit a scenario where HuC is selected alone. Therefore, we can
flip the support check to reflect the HW capabilities and fw
availability, which is more intuitive and will make it cleaner to log
HuC the difference between not supported in HW and not selected.
Removing the difference between GuC and HuC also allows us to simplify
the init_early, since we don't need to differentiate the support based
on the type of uC.

drm/i915/gt: allow setting generic data pointer
When registering debugfs files the intel gt debugfs library
forces a 'struct *gt' private data on the caller.
To be open to different usages make the new
"intel_gt_debugfs_register_files()"[*] function more generic by
converting the 'struct *gt' pointer to a 'void *' type.
I take the chance to rename the functions by using "intel_gt_" as
prefix instead of "debugfs_", so that "debugfs_gt_register_files()"
becomes "intel_gt_debugfs_register_files()".

drm/i915/gt: Stage the transfer of the virtual breadcrumb
We move the virtual breadcrumb from one physical engine to the next, if
the next virtual request is scheduled on a new physical engine. Since
the virtual context can only be in one signal queue, we need it to track
the current physical engine for the new breadcrumbs. However, to move
the list we need both breadcrumb locks -- and since we cannot take both
at the same time (unless we are careful and always ensure consistent
ordering) stage the movement of the signaler via the current virtual

drm/i915/execlists: Drop setting sibling priority hint on virtual engines
We set the priority hint on execlists to avoid executing the tasklet for
when we know that there will be no change in execution order. However,
as we set it from the virtual engine for all siblings, but only one
physical engine may respond, we leave the hint set on the others
stopping direct submission that could take place.
If we do not set the hint, we may attempt direct submission even if we
don't expect to submit. If we set the hint, we may not do any submission
until the tasklet is run (and sometimes we may park the engine before
that has had a chance). Ergo there's only a minor ill-effect on mixed
virtual/physical engine workloads where we may try and fail to do direct
submission more often than required. (Pure virtual / engine workloads
will have redundant tasklet execution suppressed as normal.)

drm/i915/display/fbc: Make fences a nice-to-have for GEN9+
dGFX has local memory so it does not have aperture or support
CPU fences but even for iGFX it have a small number of fences.
As replacement for fences to track frontbuffer modifications by CPU
we have a software tracking that is already in used by FBC and PSR.
PSR don't support fences so it shows that this tracking is reliable.
So lets make fences a nice-to-have to activate FBC for GEN9+, this
will allow us to enable FBC for dGFXs and iGFXs even when there is no
available fence.
We do not set fences to rotated planes but FBC only have restrictions
against 16bpp, so adding it here.
Also adding a new check for the tiling format, fences are only set
to X and Y tiled planes but again FBC don't have any restrictions
against tiling so adding linear as supported as well, other formats
should be added after tested but IGT only supports drawing in thse
3 formats.
intel_fbc_hw_tracking_covers_screen() maybe can also have the same
treatment as fences but BSpec is not clear if the size limitation is
for hardware tracking or general use of FBC and I don't have a 5K
display to test it, so keeping as is for safety.
v2:
- Added tiling and pixel format rotation checks
- Changed the GEN version not requiring fences to 11 from 9, DDX
needs some changes but it don't have support for GEN11+
v3:
- Changed back to GEN9+
- Moved GEN test to inside of tiling_is_valid()
v4:
- moved rotation check to its own functions
v5:
- renamed rotations_is_valid to rotation_is_valid
- moved pre-g4x rotation check to rotation_is_valid()

drm/i915/selftests: mark huge_gem_object as not shrinkable
It looks like some callers expect a non-volatile object, that they do not
want the contents of the pages lost if they happen to not be looking at it.
The shrinker however sees that we mark the pages as DONTNEED and
believes that it can freely reap them. However, since the huge object
use plain pages, they cannot be swapped out as they have no backing
storge, and the only way we can shrink them is by discarding the
contents. In light of the callers wanting to keep the contents around,
both IS_SHRINKABLE and marking the pages as volatile are incorrect.
If we drop the IS_SHRINKABLE flag we avoid the immediate issue of the
shrinker accidentally removing valuable content. We will have to
remember that a huge object is not suitable for exercising the shrinker
interaction -- although we can introduce a shrinkable one if we require.

drm/i915/edp: Ignore short pulse when panel powered off
Few edp panels like Sharp is triggering short and long
hpd pulse after panel is getting powered off.
Currently driver is already ignoring long pulse for eDP
panel but in order to process the short pulse, it turns on
the VDD which requires panel power_cycle_delay + panel_power_on_delay
these delay on Sharp panel introduced the responsiveness overhead
of 800ms in the modeset sequence and as well is in suspend
sequence.
Ignoring any short pulse if panel is powered off.
FIXME: It requires to wait for panel_power_off delay in order
to check the panel power status due to pps_lock because panel triggers
short pulse immediately after writing PP_OFF to PP_CTRL register and
wait_panel_off waits for panel_power_off delay with pps_lock held.
This still creates responsiveness overhead of panel_power_off delay.
v2:
- checking vdd along with panel power to ignore the hpd. [Jani,Ville]
v3:
- safer side check to ignore the long hpd when eDP have power,
adding type of hpd to debug log. [Jani]

drm/i915: Fix crtc nv12 etc. plane bitmasks for DPMS off
We only consider crtc_state->enable when initially calculating plane
visibility. Later on we try to override the plane's state to invisible
if the crtc is in DPMS off state (crtc_state->active==false).
Unfortunately the code doing that only updates the plane_state.visible
flag and the crtc_state.active_planes bimask, but forgets to update
some of the other plane bitmasks stored in the crtc_state. Namely
crtc_state.nv12_planes is left set up based on the original visibility
check which makes icl_check_nv12_planes() pick a slave plane for the
flagged plane in the bitmask. Later on we hit the watermark code
which sees a plane with a slave assigned and it then makes the
logical assumption that the master plane must itself be visible.
Since the master's plane_state.visible flag was already cleared
we get a WARN.
Fix the problem by clearing all the plane bitmasks for DPMS off.
This is more or less the wrong approach and instead we should
calculate all the plane related state purely based crtc_state->enable
(to guarantee that the subsequent DPMS on can't fail). However in
the past we definitely had some roadblocks to making that happen.
Not sure how many are left these days, but let's stick to the current
approach since it's a much simpler fix to the immediate problem
(the WARN).

drm/i915/dp: Add dpcd link_rate quirk for Apple 15" MBP 2017 (v3)
This fixes a problem found on the MacBookPro 2017 Retina panel.
The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec = multiplier 0xc),
but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.
This restricts the panel to 8 bpc, not providing the full
color depth of the panel.
This patch adds a quirk specific to the MBP 2017 15" Retina
panel to add the additiional 324000 kbps link rate during
edp setup.
Link to previous discussion of a different attempted fix
with Ville and Jani:
https://patchwork.kernel.org/patch/
11325935/
v2: Follow Jani's proposal of defining quirk_rates[] instead
of just appending 324000. This for better clarity.
v3: Rebased onto current drm-tip, as of 16-March-2020. Adapt
to new edid_quirks parameter of drm_dp_has_quirk().
