e45df26438 drm/rockchip: dw-mipi-dsi: Fix connector and encoder cleanup.
In bind()'s error handling path call destroy functions instead of
cleanup functions for encoder and connector and reorder to match how is
called in bind().

In unbind() call the connector and encoder destroy functions.

702791f7f2 drm/i915: add schedule out notification of preempted but completed request
There is one corner case missing schedule out notification of the preempted
request. The preempted request is just completed when preemption happen,
then it will be canceled and won't be resubmitted later, GVT-g will lost
the schedule out notification.

Here add schedule out notification if found the preempted request has been
completed.

v2:
- refine description, add completed check and notification in
  execlists_cancel_port_requests. (Chris)

v3:
- use ternary confitional, remove local variable. (Tvrtko)

c822e05918 drm/i915: expose rcs topology through query uAPI
With the introduction of asymmetric slices in CNL, we cannot rely on
the previous SUBSLICE_MASK getparam to tell userspace what subslices
are available. Here we introduce a more detailed way of querying the
Gen's GPU topology that doesn't aggregate numbers.

This is essential for monitoring parts of the GPU with the OA unit,
because counters need to be normalized to the number of
EUs/subslices/slices. The current aggregated numbers like EU_TOTAL do
not gives us sufficient information.

The Mesa series making use of this API is :

    https://patchwork.freedesktop.org/series/38795/

As a bonus we can draw representations of the GPU :

    https://imgur.com/a/vuqpa

v2: Rename uapi struct s/_mask/_info/ (Tvrtko)
    Report max_slice/subslice/eus_per_subslice rather than strides (Tvrtko)

a446ae2c6e drm/i915: add query uAPI
There are a number of information that are readable from hardware
registers and that we would like to make accessible to userspace. One
particular example is the topology of the execution units (how are
execution units grouped in subslices and slices and also which ones
have been fused off for die recovery).

At the moment the GET_PARAM ioctl covers some basic needs, but
generally is only able to return a single value for each defined
parameter. This is a bit problematic with topology descriptions which
are array/maps of available units.

This change introduces a new ioctl that can deal with requests to fill
structures of potentially variable lengths. The user is expected fill
a query with length fields set at 0 on the first call, the kernel then
sets the length fields to the their expected values. A second call to
the kernel with length fields at their expected values will trigger a
copy of the data to the pointed memory locations.

The scope of this uAPI is only to provide information to userspace,
not to allow configuration of the device.

v2: Simplify dispatcher code iteration (Tvrtko)
    Tweak uapi drm_i915_query_item structure (Tvrtko)

v3: Rename pad fields into flags (Chris)
    Return error on flags field != 0 (Chris)
    Only copy length back to userspace in drm_i915_query_item (Chris)

v4: Use array of functions instead of switch (Chris)

v5: More comments in uapi (Tvrtko)
    Return query item errors in length field (All)

v6: Tweak uapi comments style to match the coding style (Lionel)

v7: Add i915_query.h (Joonas)

v8: (Lionel) Change the behavior of the item iterator to report
    invalid queries into the query item rather than stopping the
    iteration. This enables userspace applications to query newer
    items on older kernels and only have failure on the items that are
    not supported.

v9: Edit copyright headers (Joonas)

v10: Typos & comments in uapi (Joonas)

8cc7669355 drm/i915: store all subslice masks

df99dd9202 drm/pl111: Use max memory bandwidth for resolution
We were previously selecting 1024x768 and 32BPP as the default
set-up for the PL111 consumers.

This does not work on elder systems: the device tree bindings
support a property "max-memory-bandwidth" in bytes/second that
states that if you exceed this the memory bus will saturate.
The result is flickering and unstable images.

Parse the "max-memory-bandwidth" and respect it when
intializing the driver. On the RealView PB11MP, Versatile and
Integrator/CP we get a nice console as default with this code.

2e7a66a8b5 drm/bridge: sii902x: Retry status read after DDI I2C
The following happens when connection a DVI output driven
from the SiI9022 using a DVI-to-VGA adapter plug:

i2c i2c-0: sendbytes: NAK bailout.
i2c i2c-0: sendbytes: NAK bailout.

Then no picture. Apparently the I2C engine inside the SiI9022
is not smart enough to try to fall back to DDC I2C. Or the
vendor have not integrated the electronics properly. I don't
know which one it is.

After this, the I2C bus seems stalled and the first attempt to
read the status register fails, and the code returns with
negative return value, and the display fails to initialized.

Instead, retry status readout five times and continue even
if this fails.

Tested on the ARM Versatile Express with a DVI-to-VGA
connector, it now gives picture.

Introduce a helper struct device *dev variable to make
the code more readable.

This oops happens, because analogix_dp_bind() calls drm_dp_aux_register()
which registers i2c adapter. I2C core tries to runtime get i2c host
device during registration. This ends in analogix_dp_resume(), but dp
context is NULL there. dp context is set in exynos_dp_bind() after
executing analogix_dp_bind(). Fix this issue by postponing enabling runtime
power management after drm_dp_aux_register().

a89a70a8b5 drm/i915/icl: Gen11 forcewake support
The main difference with previous GENs is that starting from Gen11
each VCS and VECS engine has its own power well, which only exist
if the related engine exists in the HW.
The fallback forcewake request workaround is only needed on gen9
according to the HSDES WA entry (1604254524), so we can go back to using
the simpler fw_domains_get/put functions.

BSpec: 18331

v2: fix fwtable, use array to test shadow tables, create new
    accessors to avoid check on every access (Tvrtko)
v3 (from Paulo): Rebase.

    to GEN >= 11
v10: Generate is_genX_shadowed with a macro (Daniele)
     Include gen11_fw_ranges in the selftest (Michel)

05f0addd9b drm/i915/icl: Enhanced execution list support
Enhanced Execlists is an upgraded version of execlists which supports
up to 8 ports. The lrcs to be submitted are written to a submit queue
(the ExecLists Submission Queue - ELSQ), which is then loaded on the
HW. When writing to the ELSP register, the lrcs are written cyclically
in the queue from position 0 to position 7. Alternatively, it is
possible to write directly in the individual positions of the queue
using the ELSQC registers. To be able to re-use all the existing code
we're using the latter method and we're currently limiting ourself to
only using 2 elements.

v2: Rebase.
v3: Switch from !IS_GEN11 to GEN < 11 (Daniele Ceraolo Spurio).
v4: Use the elsq registers instead of elsp. (Daniele Ceraolo Spurio)
v5: Reword commit, rename regs to be closer to specs, turn off

There is a slight name clashing issue because the field that we call
hw_id is actually called SW Context ID in the specs for Gen11+.

With the current size of the hw_id field we can have a maximum of 2k
contexts at any time, but we could use the sw_counter field (which is sw
defined) to increase that because the HW requirement is that
engine_id + sw id + sw_counter is a unique number.
GuC uses a similar method to support more contexts but does its tracking
at lrc level. To avoid doing an implementation that will need to be
reworked once GuC support lands, defer it for now and mark it as TODO.

v2: rebased, add documentation, fix GEN11_ENGINE_INSTANCE_SHIFT
v3: rebased, bring back lost code from i915_gem_context.c
v4: make TODO comment more generic
v5: be consistent with bit ordering, add extra checks (Chris)

edb2e5301c drm/i915: Track whether the DP link is trained or not
LSPCON likes to throw short HPDs during the enable seqeunce prior to the
link being trained. These obviously result in the channel CR/EQ check
failing and thus we schedule a pointless hotplug work to retrain the
link. Avoid that by ignoring the bad CR/EQ status until we've actually
initially trained the link.

I've not actually investigated to see what LSPCON is trying to signal
with the short pulse. But as long as it signals anything I think we're
supposed to check the link status anyway, so I don't really see other
good ways to solve this. I've not seen these short pulses being
generated by normal DP sinks.

c85d200e83 drm/i915: Move SST DP link retraining into the ->post_hotplug() hook
Doing link retraining from the short pulse handler is problematic since
that might introduce deadlocks with MST sideband processing. Currently
we don't retrain MST links from this code, but we want to change that.
So better to move the entire thing to the hotplug work. We can utilize
the new encoder->hotplug() hook for this.

The only thing we leave in the short pulse handler is the link status
check. That one still depends on the link parameters stored under
intel_dp, so no locking around that but races should be mostly harmless
as the actual retraining code will recheck the link state if we
end up there by mistake.

v2: Rebase due to ->post_hotplug() now being just ->hotplug()
    Check the connector type to figure out if we should do
    the HDMI thing or the DP think for DDI

cd46c545b7 drm/i915/breadcrumbs: Reduce signaler rbtree to a sorted list
The goal here is to try and reduce the latency of signaling additional
requests following the wakeup from interrupt by reducing the list of
to-be-signaled requests from an rbtree to a sorted linked list. The
original choice of using an rbtree was to facilitate random insertions
of request into the signaler while maintaining a sorted list. However,
if we assume that most new requests are added when they are submitted,
we see those new requests in execution order making a insertion sort
fast, and the reduction in overhead of each signaler iteration
significant.

Since commit 56299fb7d9 ("drm/i915: Signal first fence from irq handler
if complete"), we signal most fences directly from notify_ring() in the
interrupt handler greatly reducing the amount of work that actually
needs to be done by the signaler kthread. All the thread is then
required to do is operate as the bottom-half, cleaning up after the
interrupt handler and preparing the next waiter. This includes signaling
all later completed fences in a saturated system, but on a mostly idle
system we only have to rebuild the wait rbtree in time for the next
interrupt. With this de-emphasis of the signaler's role, we want to
rejig it's datastructures to reduce the amount of work we require to
both setup the signal tree and maintain it on every interrupt.

53b725c7db drm/i915/error: standardize function style in error capture
some of the static functions used from capture() have the "i915_"
prefix while other don't; most of them take i915 as a parameter, but one
of them derives it internally from error->i915. Let's be consistent by
avoiding prefix for static functions and by getting i915 from
error->i915. While at it, s/dev_priv/i915 in functions that don't
perform register reads.

of them are memory write, ioreq handler couldn't distinguish them. So
ioreq handler probe the ppgtt write handler, if it is succuess, this
ioreq is ppgtt write, otherwise it is mmio write.

So ppgtt write handler should return an error at the failure of finding

cf4ee73fd9 drm/i915/gvt: Fix guest vGPU hang caused by very high dma setup overhead
The implementation of current kvmgt implicitly setup dma mapping at MPT
API gfn_to_mfn. First this design against the API's original purpose.
Second, there is no unmap hit in this design. The result is that the
dma mapping keep growing larger and larger. For mutl-vm case, they will
consume IOMMU IOVA low 4GB address space quickly and so tons of rbtree
entries crated in the IOMMU IOVA allocator. Finally, single IOVA
allocation can take as long as ~70ms. Such latency is intolerable.

To address both above issues, this patch introduced two new MPT API:
  o dma_map_guest_page - setup dma map for guest page
  o dma_unmap_guest_page - cancel dma map for guest page

The kvmgt implements these 2 API. And to reduce dma setup overhead for
duplicated pages (eg. scratch pages), two caches are used: one is for
mapping gfn to struct gvt_dma, another is for mapping dma addr to
struct gvt_dma.

With these 2 new API, the gtt now is able to cancel dma mapping when page
table is invalidated. The dma mapping is not in a gradual increase now.

v2: follow the old logic for VFIO_IOMMU_NOTIFY_DMA_UNMAP at this point.

cd7e61b93d drm/i915/gvt: init mmio by lri command in vgpu inhibit context
There is one issue relates to Coarse Power Gating(CPG) on KBL NUC in GVT-g,
vgpu can't get the correct default context by updating the registers before
inhibit context submission. It always get back the hardware default value
unless the inhibit context submission happened before the 1st time
forcewake put. With this wrong default context, vgpu will run with
incorrect state and meet unknown issues.

The solution is initialize these mmios by adding lri command in ring buffer
of the inhibit context, then gpu hardware has no chance to go down RC6 when
lri commands are right being executed, and then vgpu can get correct
default context for further use.

v3:
- fix code fault, use 'for' to loop through mmio render list(Zhenyu)

v4:
- save the count of engine mmio need to be restored for inhibit context and
  refine some comments. (Kevin)

v5:
- code rebase

b6c126a393 drm/i915/gvt: Manage shadow pages with radix tree
We don't know how many page tables will be shadowed. It varies
considerably corresponding to guest load. Radix tree is a better
choice for us. Since Page Frame Number is used as key so most of
the bits are common.

Here is some performance data (duration in us) of looking up a
element:
Before: (aka. ppgtt_find_shadow_page)
 0.308 0.292 0.246 0.432 0.143 ... 0.311 0.225 0.382 0.199 0.325
After: (aka. intel_vgpu_find_spt_by_mfn)
 0.106 0.106 0.107 0.106 0.105 0.107 ... 0.107 0.109 0.105 0.108

This time I didn't get the early data of hash table. The data is
measured when desktop is shown.

As last change, the overall benchmark almost is not changed, but
we get better scalability.

e502a2af4c drm/i915/gvt: Provide generic page_track infrastructure for write-protected page
This patch provide generic page_track infrastructure for write-protected
guest page. The old page_track logic gets rewrote and now stays in a new
standalone page_track.c. This page track infrastructure can be both used
by vGUC and GTT shadowing.

The important change is that it uses radix tree instead of hash table.
We don't have a predictable number of pages that will be tracked.

Here is some performance data (duration in us) of looking up a element:
Before: (aka. intel_vgpu_find_tracked_page)
 0.091 0.089 0.090 ... 0.093 0.091 0.087 ... 0.292 0.285 0.292 0.291
After: (aka. intel_vgpu_find_page_track)
 0.104 0.105 0.100 0.102 0.102 0.100 ... 0.101 0.101 0.105 0.105

The hash table has good performance at beginning, but turns bad with
more pages being tracked even no 3D applications are running. As
expected, radix tree has stable duration and very quick.

The overall benchmark (tested with Heaven Benchmark) marginally improved
since this is not the bottleneck. What we benefit more from this change
is scalability.

shadow page table - w/ or wo/ a guest page associated with. A pure shadow
page (no guest page associated) will be used to shadow splited 2M huge
gtt. In this case, the spt.guest_page.gfn should be a zero.

To search a existed shadow page table, we have two new interfaces:
 - intel_vgpu_find_spt_by_gfn(), find a spt by guest gfn. It must not
   be a pure spt.
 - intel_vgpu_find_spt_by_mfn, Find the spt using shadow page mfn in

Now we only manage ppgtt mm object with mm->ppgtt_mm.lru_list. No need
to mix ppgtt and ggtt together, since one vGPU only has one ggtt object.

v4: Don't invoke ppgtt_free_all_shadow_page before intel_vgpu_destroy_all_ppgtt_mm.
v3: Add GVT_RING_CTX_NR_PDPS to avoid confusing about the PDPs.
v2: Split some changes into small standalone patches.

b58f0c81e9 drm/amd/display: disable CRTCs with NULL FB on their primary plane (V2)
The below commit

"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"

introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.

This change leads to BUG hit while performing atomic commit on amd driver.

As a fix this patch ensures that we disable the CRTC's with NULL FB by returning
-EINVAL and hence triggering fall back to the old behavior and turning off the
crtc in atomic_remove_fb().

V2: Added error check for plane_state and removed sanity check for crtc.

c21b68c5eb drm/amd/display: defer modeset check in dm_update_planes_state
amdgpu_dm_atomic_check() is used to validate the entire configuration of
planes and crtc's that the user space wants to commit.

However amdgpu_dm_atomic_check() depends upon DRM_MODE_ATOMIC_ALLOW_MODESET
flag else its mostly dummy.
Its not mandatory for the user space to set DRM_MODE_ATOMIC_ALLOW_MODESET,
and in general its not set either along with DRM_MODE_ATOMIC_TEST_ONLY.

Considering its importantance, this patch defers the allow_modeset check
in dm_update_planes_state(), so that there shall be scope to validate
the configuration sent from user space, without impacting the population
of dc/dm related data structures.

This patch fixed secondary screen only S4 resume, eDP is unintentionally
light up due to incorrect dpms off flag.

When entering S4, dpms off flags are set to true via
set power state. During resume, eDP is light up by vbios, so the flags
should be changed to false to match the real state.
By change the flag properly, eDP is able to be turned off properly as per
OS request.

This change may affect S3/S4 Shut down resume IOIC, need to verify
those cases.

086247a4b2 drm/amd/display: Use 4096 lut entries
Points in the DRM LUT are spaced linearly. Points in hardware are spaced
exponentially, with greater density towards 0. To maintain low-end
accuracy in hardware when sampling the DRM LUT, more points are needed.

However, X doesn't seem to play with legacy LUTs of such size.
Therefore, check for legacy lut when updating DC states, and update
accordingly.

v2: Use a macro for the maximum drm LUT value.

v3: Update commit to reflect that this does not map 1-1 to HW

During reset/wedging, we have to clean up the requests on the timeline
and flush the pending interrupt state. Currently, we are abusing the irq
disabling of the timeline spinlock to protect the irq state in
conjunction to the engine's timeline requests, but this is accidental
and conflates the spinlock with the irq state. A baffling state of
affairs for the reader.

Instead, explicitly disable irqs over the critical section, and separate
modifying the irq state from the timeline's requests.

aebbc2d7b3 drm/i915/execlists: Move irq state manipulation inside irq disabled region
Although this state (execlists->active and engine->irq_posted) itself is
not protected by the engine->timeline spinlock, it does conveniently
ensure that irqs are disabled. We can use this to protect our
manipulation of the state and so ensure that the next IRQ to arrive sees
consistent state and (hopefully) ignores the reset engine.

the conclusion is that the only place where the ports are reset to zero,
is from engine->cancel_requests called during i915_gem_set_wedged().

The race is horrible as it results from calling set-wedged on active HW
(the GPU reset failed) and as such we need to be careful as the HW state
changes beneath us. Fortunately, it's the same scary conditions as
affect normal reset, so we can reuse the same machinery to disable state
tracking as we clobber it.

fee0fddc1d drm/i915/gen9, gen10: Disable FBC on planes with a misaligned Y-offset
Enabling FBC on a plane having a Y-offset that isn't divisible by 4 may
cause pipe FIFO underruns and flickers, so disable FBC on such a config.

I tried the followings to work around the issue:
- enable each HW work around in ILK_DPFC_CHICKEN
- disable each compression algorithm in ILK_DPFC_CONTROL
- disable low-power watermarks
None of the above got rid of the problem. I haven't found this issue in
the Bspec/WA database either.

Besides the igt testcase below (yet to be merged) an easy way to
reproduce the issue is to enable a plane with FBC and a plane Y-offset
not aligned to 4 and then just enable/disable FBC in a loop, keeping the
plane enabled.

I could trigger the problem on BXT/GLK/SKL/CNL, so assume for now that it's
only present on GEN9 and GEN10.

v2: (Ville)
- Run the test/apply the WA on CNL as well.
- Use IS_GEN() instead of INTEL_GEN().
- Fix spelling.

Update the code to progam the YCbCr->RGB CSC mode correctly when

The spec is rather confusing as it calls the mode "YUV601 to RGB709".
I'm going to assume that just means it's going to use the YCbCr->RGB

5deae91911 drm/i915: Correctly handle limited range YCbCr data on VLV/CHV
Turns out the VLV/CHV fixed function sprite CSC expects full range
data as input. We've been feeding it limited range data to it all
along. To expand the data out to full range we'll use the color
correction registers (brightness, contrast, and saturation).

On CHV pipe B we were actually doing the right thing already because we
progammed the custom CSC matrix to do expect limited range input. Now
that well pre-expand the data out with the color correction unit, we
need to change the CSC matrix to operate with full range input instead.

This should make the sprite output of the other pipes match the sprite
output of pipe B reasonably well. Looking at the resulting pipe CRCs,
there can be a slight difference in the output, but as I don't know
the formula used by the fixed function CSC of the other pipes, I don't
think it's worth the effort to try to match the output exactly. It
might not even be possible due to difference in internal precision etc.

One slight caveat here is that the color correction registers are single
bufferred, so we should really be updating them during vblank, but we
still don't have a mechanism for that, so just toss in another FIXME.
