dbf56ab11a drm/amdkfd: Remove usage of alloc(sizeof(struct...
See https://kernel.org/doc/html/latest/process/coding-style.html
under "14) Allocating Memory" for rationale behind removing the
x=alloc(sizeof(struct) style and using x=alloc(sizeof(*x) instead

ab7c164867 drm/amdkfd: Fix goto usage v2
Remove gotos that do not feature any common cleanup, and use gotos
instead of repeating cleanup commands.

According to kernel.org: "The goto statement comes in handy when a
function exits from multiple locations and some common work such as
cleanup has to be done. If there is no cleanup needed then just return
directly."

v2: Applied review suggestions in create_queue_nocpsch

4eacc26b3b drm/amdkfd: Change x==NULL/false references to !x
Upstream prefers the !x notation to x==NULL or x==false. Along those lines
change the ==true or !=NULL references as well. Also make the references
to !x the same, excluding () for readability.

79775b627d drm/amdkfd: Consolidate and clean up log commands
Consolidate log commands so that dev_info(NULL, "Error...") uses the more
accurate pr_err, remove the module name from the log (can be seen via
dynamic debugging with +m), and the function name (can be seen via
dynamic debugging with +f). We also don't need debug messages saying
what function we're in. Those can be added by devs when needed

Don't print vendor and device ID in error messages. They are typically
the same for all GPUs in a multi-GPU system. So this doesn't add any
value to the message.

Lastly, remove parentheses around %d, %i and 0x%llX.
According to kernel.org:
"Printing numbers in parentheses (%d) adds no value and should be
avoided."

efa479352f drm/nouveau: Fix merge commit
The most recent merge commit in airlied/drm-next has problems with
confusing old_crtc_state and new_crtc_state. Use the
for_each_oldnew_crtc_in_state macros to clean up the confusion,
and explicitly look at the correct state instead of looking at
asyh->state.

With these fixes it becomes more obvious what the code is trying to do,
which will hopefully prevent future confusion.

dc911f5bd8 drm/i915/edp: Allow alternate fixed mode for eDP if available.
Some fixed resolution panels actually support more than one mode,
with the only thing different being the refresh rate.  Having this
alternate mode available to us is desirable, because it allows us to
test PSR on panels whose setup time at the preferred mode is too long.
With this patch we allow the use of the alternate mode if it's
available and it was specifically requested.

If a ring is not initialized, it also should not be finished.
For example, in Vega10's SR-IOV environment, UVD's decode ring is not
initialized, but will be finnished in amdgpu_uvd_sw_fini, because UVD
driver put all the uvd decode ring's finish operation into
amdgpu_uvd_sw_fini function, while not uvd_vXXX_0_sw_fini. This will
lead to amdgpu module unloading failure.

the Pitcairn initialization silently falls through the Cape Verde

intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

cf6e7bac63 drm/i915: Add support for drm syncobjs
This commit adds support for waiting on or signaling DRM syncobjs as
part of execbuf.  It does so by hijacking the currently unused cliprects
pointer to instead point to an array of i915_gem_exec_fence structs
which containe a DRM syncobj and a flags parameter which specifies
whether to wait on it or to signal it.  This implementation
theoretically allows for both flags to be set in which case it waits on
the dma_fence that was in the syncobj and then immediately replaces it
with the dma_fence from the current execbuf.

v2:
 - Rebase on new syncobj API
v3:
 - Pull everything out into helpers
 - Do all allocation in gem_execbuffer2
 - Pack the flags in the bottom 2 bits of the drm_syncobj*
v4:
 - Prevent a potential race on syncobj->fence

Testcase: igt/gem_exec_fence/syncobj*

b805014897 drm/i915: Handle full s64 precision for wait-ioctl
The wait-ioctl is optionally supplied a timeout with nanosecond
precision in a s64 field. We use nsecs_to_jiffies64() to convert that
into the jiffies consumed by the scheduler, but internally
nsecs_to_jiffies64() does not guard against overflow (as it's purpose is
for use by the scheduler and not drivers!). So we must guard against the
overflow ourselves, and in the process note that we may then return
much earlier than the timeout selected by the user, so don't report
ETIME unless we do hit the timeout. (Woe betold us though if the user
waits for a year (32bit) and the request is still not complete!)

v2: Refine overflow detection (to not include an overffow itself)

b8f55be644 drm/i915: Split obj->cache_coherent to track r/w
Another month, another story in the cache coherency saga. This time, we
come to the realisation that i915_gem_object_is_coherent() has been
reporting whether we can read from the target without requiring a cache
invalidate; but we were using it in places for testing whether we could
write into the object without requiring a cache flush. So split the
tracking into two, one to decide before reads, one after writes.

See commit e27ab73d17 ("drm/i915: Mark CPU cache as dirty on every
transition for CPU writes") for the previous entry in this saga.

v2: Be verbose
v3: Remove unused function (i915_gem_object_is_coherent)
v4: Fix inverted coherency check prior to execbuf (from v2)
v5: Add comment for nasty code where we are optimising on gcc's behalf.

6b3816d696 drm/i915/gvt: Fix guest i915 full ppgtt blocking issue
Guest i915 full ppgtt functionality was blocking by an issue, which would
lead to gpu hardware hang. Guest i915 driver may update the ppgtt table
just before this workload is going to be submitted to the hardware by
device model. This case wasn't handled well by device model before, due
to the small time window between removing old ppgtt entry and adding the
new one. Errors occur when the workload is executed by hardware during
that small time window. This patch is to remove this time window by adding
the new ppgtt entry first and then remove the old one.

Changes in v2:
- Move VGT_CAPS_FULL_PPGTT introduction to patch 2/4. (Joonas)

Changes since v2:
- Divide the whole patch set into two separate patch series, with one
  patch in i915 side to check guest i915 full ppgtt capability and enable
  it when this capability is supported by the device model, and the other
  one in gvt side which fixs the blocking issue and enables the device
  model to provide the capability to guest. And this patch focuses on gvt

8a4ab66f38 drm/i915: Enable guest i915 full ppgtt functionality
Enable the guest i915 full ppgtt functionality when host can provide this
capability. vgt_caps is introduced to guest i915 driver to get the vgpu
capabilities from the device model. VGT_CPAS_FULL_PPGTT is one of the
capabilities type to let guest i915 dirver know that the guest i915 full
ppgtt is supported by device model.

Notice that the minor version of pvinfo isn't bumped because of this
vgt_caps introduction, due to older guest would be broken by simply
increasing the pvinfo version. Although the pvinfo minor version doesn't
increase, the compatibility won't be blocked. The compatibility is ensured
by checking the value of caps field in pvinfo. Zero means no full ppgtt
support and BIT(2) means this feature is provided.

Changes since v1:
- Use u32 instead of uint32_t (Joonas)
- Move VGT_CAPS_FULL_PPGTT introduction to this patch and use #define
  instead of enum (Joonas)
- Rewrite the vgpu full ppgtt capability checking logic. (Joonas)
- Some coding style refine. (Joonas)

Changes since v2:
- Divide the whole patch set into two separate patch series, with one
  patch in i915 side to check guest i915 full ppgtt capability and enable
  it when this capability is supported by the device model, and the other
  one in gvt side which fixs the blocking issue and enables the device
  model to provide the capability to guest. And this patch focuses on guest
  i915 side. (Joonas)
- Change the title from "introduce vgt_caps to pvinfo" to
  "Enable guest i915 full ppgtt functionality". (Tina)

Change since v3:
- Add some comments about pvinfo caps and version. (Joonas)

Change since v4:
- Tested by Tina Zhang.

Change since v5:
- Add limitation about supporting 32bit full ppgtt.

Change since v6:
- Change the fallback to 48bit full ppgtt if i915.ppgtt_enable=2. (Zhenyu)

Change in v9:
- Remove the fixme comment due to no plan for 32bit full ppgtt
  support. (Zhenyu)
- Reorder the patch-set to fix compiling issue with git-bisect. (Zhenyu)
- Add print log when forcing guest 48bit full ppgtt. (Zhenyu)

v10:
- Update against Joonas's has_full_ppgtt and has_full_48bit_ppgtt disconnect
  change. (Zhenyu)

9db529aac9 drm/i915: More surgically unbreak the modeset vs reset deadlock
There's no reason to entirely wedge the gpu, for the minimal deadlock
bugfix we only need to unbreak/decouple the atomic commit from the gpu
reset. The simplest way to fix that is by replacing the
unconditional fence wait a the top of commit_tail by a wait which
completes either when the fences are done (normal case, or when a
reset doesn't need to touch the display state). Or when the gpu reset
needs to force-unblock all pending modeset states.

The lesser source of deadlocks is when we try to pin a new framebuffer
and run into a stall. There's a bunch of places this can happen, like
eviction, changing the caching mode, acquiring a fence on older
platforms. And we can't just break the depency loop and keep going,
the only way would be to break out and restart. But the problem with
that approach is that we must stall for the reset to complete before
we grab any locks, and with the atomic infrastructure that's a bit
tricky. The only place is the ioctl code, and we don't want to insert
code into e.g. the BUSY ioctl. Hence for that problem just create a
critical section, and if any code is in there, wedge the GPU. For the
steady-state this should never be a problem.

Note that in both cases TDR itself keeps working, so from a userspace
pov this trickery isn't observable. Users themselvs might spot a short
glitch while the rendering is catching up again, but that's still
better than pre-TDR where we've thrown away all the rendering,
including innocent batches. Also, this fixes the regression TDR
introduced of making gpu resets deadlock-prone when we do need to
touch the display.

One thing I noticed is that gpu_error.flags seems to use both our own
wait-queue in gpu_error.wait_queue, and the generic wait_on_bit
facilities. Not entirely sure why this inconsistency exists, I just
picked one style.

A possible future avenue could be to insert the gpu reset in-between
ongoing modeset changes, which would avoid the momentary glitch. But
that's a lot more work to implement in the atomic commit machinery,
and given that we only need this for pre-g4x hw, of questionable
utility just for the sake of polishing gpu reset even more on those
old boxes. It might be useful for other features though.

v2: Rebase onto 4.13 with a s/wait_queue_t/struct wait_queue_entry/.

v3: Really emabarrassing fixup, I checked the wrong bit and broke the
unbreak/wakeup logic.

v4: Also handle deadlocks in pin_to_display.

v5: Review from Michel:
- Fixup the BUILD_BUG_ON
- Don't forget about the overlay

42b062b0d9 drm/i915: Push i915_sw_fence_wait into the nonblocking atomic commit
Blocking in a worker is ok, that's what the unbound_wq is for. And it
unifies the paths between the blocking and nonblocking commit, giving
me just one path where I have to implement the deadlock avoidance
trickery in the next patch.

I first tried to implement the following patch without this rework, but
force-completing i915_sw_fence creates some serious challenges around
properly cleaning things up. So wasn't a feasible short-term approach.
Another approach would be to simple keep track of all pending atomic
commit work items and manually queue them from the reset code. With the
caveat that double-queue in case we race with the i915_sw_fence must be
avoided. Given all that, taking the cost of a double schedule in atomic
for the short-term fix is the best approach, but can be changed in the future of course.

v2: Amend commit message (Chris).

v3: Add comment explaining why we do nothing in the sw_fence complete
callback (Michel).

97154ec242 drm/i915: Avoid the gpu reset vs. modeset deadlock
... using the biggest hammer we have. This is essentially a weaponized
version of the timeout-based wedging Chris added in

commit 36703e79a9
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Thu Jun 22 11:56:25 2017 +0100

    drm/i915: Break modeset deadlocks on reset

Because defense-in-depth is good it's good to still have both. Also
note that with the locking change we can now restrict this a lot (old
gpus and special testing only), so this doesn't kill the TDR benefits
on at least anything remotely modern.

And futuremore with a few tricks it should be possible to make a much
more educated guess about whether an atomic commit is stuck waiting on
the gpu (atomic_t counting the pending i915_sw_fence used by the
atomic modeset code should do it), so we can improve this.

But for now just start with something that is guaranteed to recover
faster, for much better CI througput.

This defacto reverts TDR on these platforms, but there's not really a
single commit to specify as the sole offender.

v2: Add a debug message to explain what's going on. We can't DRM_ERROR
because that spams CI. And the timeout based fallback still prints a
DRM_ERROR, in case something goes wrong.

v3: Fix comment layout (Michel)

12124bea5b drm/i915: Suppress switch_mm emission between the same aliasing_ppgtt
When switching between contexts using the aliasing_ppgtt, the VM is
shared. We don't need to reload the PD registers unless they are dirty.

Martin Peres reported an issue that looks like corruption between
Haswell context switches, bisecting to commit f9326be5f1 ("drm/i915:
Rearrange switch_context to load the aliasing ppgtt on first use").
Switching between the same mm (the aliasing_ppgtt is used for all
contexts in this case) should be a nop, but appears to trigger some
side-effects in the context switch. However, as we know the switch
is redundant in this case, we can skip it and continue to ignore the
issue until somebody feels strong enough to investigate full-ppgtt on
gen7 again!

Except.. Martin was using full-ppgtt which is not supported as it
doesn't work correctly yet. So whilst the bisect did yield valuable
information about the failures, the fix should not have any user impact
under default settings, with the exception of a slightly lower
throughput on xcs as the VM would always be reloaded.

v2: Also remember to set the legacy_active_context following the switch
on xcs (commit e8a9c58fcd ("drm/i915: Unify active context tracking
between legacy/execlists/guc"))

2ae9e3653f drm/i915/fbc: only update no_fbc_reason when active
In our snb farm in CI we have plenty of underruns, but not enough
stolen memory to enable fbc. Which means every time there's an
underrun the no_fbc_reason swichtes to something that makes
kms_frontbuffer_tracking fail instead of skip, adding massive amounts
of additional noise to igt test runs.

Make sure we don't try to disable fbc when it's off already.

2e45eeac7c drm: Only lastclose on unload for legacy drivers
The only thing modern drivers are supposed to do in lastclose is
restore the fb emulation state. Which is entirely optional, and
there's really no reason to do that. So restrict it to legacy drivers
(where the driver cleanup essentially happens in lastclose).

This will also allow us to share the unregister function with
drm_dev_unplug().

Quoting my reply to Alex on dri-devel:

So I think there's 3 cases:
- Trying to unload the module. You can't do that while anyone has the
fd still open, so lastclose is guaranteeed to run.
- Forcefully unbinding the driver through sysfs. Not any better, since
the can_switch stuff checks for the open count, and so will delay the
delayed switch no matter what.
- Actual hotremoval: a) not implemented since none of the drivers
taking part in vgaswitcheroo correctly unplug the drm device and b)
you can't hotremove a chip from a laptop.

v2: Extend commit message with m-l discussion.

714244e280 drm/i915: Add format modifiers for Intel
This was based on a patch originally by Kristian. It has been modified
pretty heavily to use the new callbacks from the previous patch.

v2:
  - Add LINEAR and Yf modifiers to list (Ville)
  - Combine i8xx and i965 into one list of formats (Ville)
  - Allow 1010102 formats for Y/Yf tiled (Ville)

v3:
  - Handle cursor formats (Ville)
  - Put handling for LINEAR in the mod_support functions (Ville)

v4:
  - List each modifier explicitly in supported modifiers (Ville)
  - Handle the CURSOR plane (Ville)

v5:
  - Split out cursor and sprite handling (Ville)

v6:
  - Actually use the sprite funcs (Emil)
  - Use unreachable (Emil)

v7:
  - Only allow Intel modifiers and LINEAR (Ben)

v8
  - Fix spite assert introduced in v6 (Daniel)

v9
  - Change vendor check logic to avoid magic 56 (Emil)
  - Reorder skl_mod_support (Ville)
  - make intel_plane_funcs static, could be done as of v5 (Ville)
  - rename local variable intel_format_modifiers to modifiers (Ville)
    - actually use sprite modifiers
  - split out modifier/formats by platform (Ville)

v10:
  - Undo vendor check from v9

v11:
  - Squash CCS advertisement into this patch (daniels)
  - Don't advertise CCS on higher sprite planes (daniels)

v12:
  - Don't advertise Y-tiled or CCS on any sprite planes, since we don't
    allocate enough DDB space for it to work. (daniels)

2e2adb0573 drm/i915: Add render decompression support
SKL+ display engine can scan out certain kinds of compressed surfaces
produced by the render engine. This involved telling the display engine
the location of the color control surfae (CCS) which describes
which parts of the main surface are compressed and which are not. The
location of CCS is provided by userspace as just another plane with its
own offset.

Add the required stuff to validate the user provided AUX plane metadata
and convert the user provided linear offset into something the hardware
can consume.

Due to hardware limitations we require that the main surface and
the AUX surface (CCS) be part of the same bo. The hardware also
makes life hard by not allowing you to provide separate x/y offsets
for the main and AUX surfaces (excpet with NV12), so finding suitable
offsets for both requires a bit of work. Assuming we still want keep
playing tricks with the offsets. I've just gone with a dumb "search
backward for suitable offsets" approach, which is far from optimal,
but it works.

Also not all planes will be capable of scanning out compressed surfaces,
and eg. 90/270 degree rotation is not supported in combination with
decompression either.

This patch may contain work from at least the following people:
* Vandana Kannan <vandana.kannan@intel.com>
* Daniel Vetter <daniel@ffwll.ch>
* Ben Widawsky <ben@bwidawsk.net>

v2: Deal with display workarounds 0390, 0531, 1125 (Paulo)
v3: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
    Put the AUX register defines to the correct place
    Fix up the slightly bogus rotation check
v4: Use I915_WRITE_FW() due to plane update locking changes
    s/return -EINVAL/goto err/ in intel_framebuffer_init()
    Eliminate a bunch hardcoded numbers in CCS code

bbfb6ce86c drm/i915: Implement .get_format_info() hook for CCS
SKL+ display engine can scan out certain kinds of compressed surfaces
produced by the render engine. This involved telling the display engine
the location of the color control surfae (CCS) which describes which
parts of the main surface are compressed and which are not. The location
of CCS is provided by userspace as just another plane with its own offset.

By providing our own format information for the CCS formats, we should
be able to make framebuffer_check() do the right thing for the CCS
surface as well.

Note that we'll return the same format info for both Y and Yf tiled
format as that's what happens with the non-CCS Y vs. Yf as well. If
desired, we could potentially return a unique pointer for each
pixel_format+tiling+ccs combination, in which case we immediately be
able to tell if any of that stuff changed by just comparing the
pointers. But that does sound a bit wasteful space wise.

v2: Drop the 'dev' argument from the hook
v3: Include the description of the CCS surface layout
v4: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
v5: Re-drop 'dev', fix commit message, add missing drm_fourcc.h
    description of CCS layout. (daniels)

3ec0af7f22 drm/i915: Supply the engine-id for our mock_engine()
In the original selftest, we didn't care what the engine->id was, just
that it could uniquely identify it. Later though, we started tracking
the mock engines in the fixed size arrays around the drm_i915_private and
so we now require their indices to be correct. This becomes an issue when
using the standalone harness which runs all available tests at module load,
and so we quickly assign an out-of-bounds index to an engine as we
reallocate the mock GEM device between tests. It doesn't show up in
igt/drv_selftest as that runs each subtest individually.

9dfb8e5b91 drm/i915/gvt: Add shadow context descriptor updating
The current context logic only updates the descriptor of context when
it's being pinned to graphics memory space. But this cannot satisfy the
requirement of shadow context. The addressing mode of the pinned shadow
context descriptor may be changed according to the guest addressing mode.
And this won't be updated, as the already pinned shadow context has no
chance to update its descriptor. And this will lead to GPU hang issue,
as shadow context is used with wrong descriptor. This patch fixes this
issue by letting the pinned shadow context descriptor update its
addressing mode on demand.

This patch fixes GPU HANG issue which happends after changing the
grub parameter i915.enable_ppgtt form 0x01 to 0x03 or vice versa and
then rebooting the guest.

f846c8de64 drm/i915/gvt: Optimize ring siwtch 2x faster by removing unnecessary POSTING_READ
There are lots of POSTING_READ alongside each mmio write Op. While
actually this is not necessary. It just bring too much latency since
PCIe read Op is very slow which is of non-posted transaction.

For PCIe device, the mem transaction for strong ordering rules are:
  o PCIe mmio write sequence is FIFO. Posted request cannot
    pass previous posted request.
  o PCIe mmio read will not go ahead of previous write.

Intel graphics doesn't support RO, so we can apply above rules. In
our case, we only need one POSTING_READ at last. This can remove
half of mmio read Op and then the average ring switch performance
is nearly doubled.

912d64123d drm/i915/psr: Preserve SRD_CTL bit 29 on PSR init
Bit 29 of SRD_CTL needs to have its value preserved according to the
B-Spec, so right before we write out the register we go ahead and read
the register and preserve the value of that bit before we write out
the configured register value.

1899bd5757 drm/exynos: forbid creating framebuffers from too small GEM buffers
Add a check if the framebuffer described by the provided drm_mode_fb_cmd2
structure fits into provided GEM buffers. Without this check it is
possible to create a framebuffer object from a small buffer and set it to
the hardware, what results in displaying system memory outside the
allocated GEM buffer.

802673d66f drm/i915: Perform an invalidate prior to executing golden renderstate
As we may have just bound the renderstate into the GGTT for execution, we
need to ensure that the GTT TLB are also flushed.

On snb-gt2, this would cause a random GPU hang at the start of a new
context (e.g. boot) and on snb-gt1, it was causing the renderstate batch
to take ~10s. It was the GPU hang that revealed the truth, as the CS
gleefully executed beyond the end of the golden renderstate batch, a good
indicator for a GTT TLB miss.

482b0e3c2f drm: Nuke drm_atomic_helper_connector_set_property
It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_connector_set_property.

The only special case is nouveau which used one function for both
pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

144a7999d6 drm: Handle properties in the core for atomic drivers
The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

4a97a3da42 drm: Don't update property values for atomic drivers
Atomic drivers only use the property value store for immutable (i.e.
can't be set by userspace, but the kernel can still adjust it)
properties. The only tricky part is the removal of the update in
drm_atomic_helper_update_legacy_modeset_state().

This was added in

    drm/i915: update dpms property in set_mode

for the legacy modeset code. The reason we needed this hack was that
i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of
the newer-ish drm_drv_uses_atomic_modeset(), which avoids such
troubles. With the correct feature checks this isn't needed anymore at
all.

Also make sure that drivers don't accidentally get this wrong by
making the exported version of drm_object_property_get_value() only
work for legacy drivers. Only gma500 uses it anyway.

3dfeb631a1 drm/omap: Rework the rotation-on-crtc hack
I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

v4: Review from Laurent
- Move struct omap_crtc_state into omap_crtc.c
- Clean up comments.
- Don't forget to copy the shadowed state over on duplicate.

v5: Don't forget to update the reset handler (Maarten).
v6: Update omap_crtc_state shadow values in omap_crtc_atomic_check (Maarten).
v7:
- Fix get_property to return 0 and set value in *val (Maarten).

c93f6092df drm: bridge: synopsys/dw-hdmi: Provide default configuration function for HDMI 2.0 PHY
Currently HDMI 2.0 PHYs do not have a default configuration function.

As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D
PHYs we can provide the same default configuration function for both
and still let user overwrite this with custom configuration function
if needed.

If, for some reason, the PHY is custom or has a register different
register layout then custom configuration function *must* be provided
in order for the system to work correctly. As we prefer the pdata
provided configuration function over the internal one this change
will not make any impact in custom platforms.

7cc4ab225a drm/bridge: dw-hdmi: add better clock disable control
The video setup path aways sets the clock disable register to a specific
value, which has the effect of disabling the CEC engine.  When we add the
CEC driver, this becomes a problem.

Fix this by only setting/clearing the bits that the video path needs to.

e9d7486eac drm/i915: fix backlight invert for non-zero minimum brightness
When we started following the backlight minimum brightness in
6dda730e55 ("drm/i915: respect the VBT minimum backlight brightness")
we overlooked the brightness invert quirk. Even if we invert the
brightness, we need to take the min limit into account. We probably
missed this because the invert has only been required on gen4 for proper
operation.

9ed85e14e9 drm: mgag200: remove dead code and pointless local lut storage
The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code and hook up the crtc .gamma_set
to use the crtc gamma_store directly instead of duplicating that
info locally.

7490831735 drm: i915: remove dead code and pointless local lut storage
The driver stores lut values from the fbdev interface, and is able
to give them back, but does not appear to do anything with these
lut values. The generic fb helpers have replaced this function,
and may even have made the driver work for the C8 mode from the
fbdev interface. But that is untested.

Since the fb helpers .gamma_set and .gamma_get are obsolete,
remove the dead code.

No functional change.

KBP was based on SPT and spec wasn't clear about the full name.
There was the initial point of the "Point" confusion.

Later the split with Coffee Lake and Cannon Lake both using CNP
and also some uncertainty from the specs we had at that time
made us to propagated the mistake along.

So, let's fix this now and avoid propagating these wrong
"points".

f461bd2b49 drm/fb-helper: add new drm_setup_crtcs_fb() function
This adds a new drm_setup_crtcs_fb() function to handle the parts of
drm_setup_crtcs() that touch fb_helper->fb and fb_helper->fbdev. When
drm_setup_crtcs() is called during initialization, these fields are NULL
because they have not been allocated yet.

There is currently a hack at the end of drm_fb_helper_single_fb_probe()
that sets fb_helper->fb, so it is moved to the new drm_setup_crtcs_fb()
function.

This is also done in preparation for addition setup that requires access
to fb_helper->fbdev.

f89823c212 drm/i915/perf: Implement I915_PERF_ADD/REMOVE_CONFIG interface
The motivation behind this new interface is expose at runtime the
creation of new OA configs which can be used as part of the i915 perf
open interface. This will enable the kernel to learn new configs which
may be experimental, or otherwise not part of the core set currently
available through the i915 perf interface.

v2: Drop DRM_ERROR for userspace errors (Matthew)
    Add padding to userspace structure (Matthew)
    s/guid/uuid/ (Matthew)

v3: Use u32 instead of int to iterate through registers (Matthew)

v4: Lock access to dynamic config list (Lionel)

v5: by Matthew:
    Fix uninitialized error values
    Fix incorrect unwiding when opening perf stream
    Use kmalloc_array() to store register
    Use uuid_is_valid() to valid config uuids
    Declare ioctls as write only
    Check padding members are set to 0
    by Lionel:
    Return ENOENT rather than EINVAL when trying to remove non
    existing config

v6: by Chris:
    Use ref counts for OA configs
    Store UUID in drm_i915_perf_oa_config rather then using pointer
    Shuffle fields of drm_i915_perf_oa_config to avoid padding

v7: by Chris
    Rename uapi pointers fields to end with '_ptr'

v8: by Andrzej, Marek, Sebastian
    Update register whitelisting
    by Lionel
    Add more register names for documentation
    Allow configuration programming in non-paranoid mode
    Add support for value filter for a couple of registers already
    programmed in other part of the kernel

v9: Documentation fix (Lionel)
    Allow writing WAIT_FOR_RC6_EXIT only on Gen8+ (Andrzej)

701f8231a2 drm/i915/perf: prune OA configs
In the following commit we'll introduce loadable userspace
configs. This change reworks how configurations are handled in the
perf driver and retains only the test configurations in kernel space.

We now store the test config in dev_priv and resolve the id only once
when opening the perf stream. The OA config is then handled through a
pointer to the structure holding the configuration details.

v2: Rework how test configs are handled (Lionel)

v3: Use u32 to hold number of register (Matthew)

v4: Removed unused dev_priv->perf.oa.current_config variable (Matthew)

v5: Lock device when accessing exclusive_stream (Lionel)

v6: Ensure OACTXCONTROL is always reprogrammed (Lionel)

v7: Switch a couple of index variable from int to u32 (Matthew)

5e0594fd77 drm: rcar-du: Repair vblank for DRM page flips using the VSP
The driver recently switched from handling page flip completion in the
DU vertical blanking handler to the VSP frame end handler to fix a race
condition. This unfortunately resulted in incorrect timestamps in the
vertical blanking events sent to userspace as vertical blanking is now
handled after sending the event.

To fix this we must reverse the order of the two operations. The easiest
way is to handle vertical blanking in the VSP frame end handler before
sending the event. The VSP frame end interrupt occurs approximately 50µs
earlier than the DU frame end interrupt, but this should not cause any
undue harm.

As we need to handle vertical blanking even when page flip completion is
delayed, the VSP driver now needs to call the frame end completion
callback unconditionally, with a new argument to report whether page
flip has completed.

With this new scheme the DU vertical blanking interrupt isn't needed
anymore, so we can stop enabling it.

d6160246f6 drm: rcar-du: Wait for flip completion instead of vblank in commit tail
Page flips can take more than one vertical blanking to complete if
arming the page flips races with the vertical blanking interrupt.
Waiting for one vblank to complete the atomic commit in the commit tail
handler is thus incorrect, and can lead to framebuffers being released
while still being scanned out.

Fix this by waiting for flip completion instead, using the

Commit 52055bafa1 ("drm: rcar-du: Move plane commit code from CRTC
start to CRTC resume") changed the order of the plane commit and CRTC
enable operations to accommodate the runtime PM requirements. However,
this introduced corruption in the first displayed frame, as the CRTC is
now enabled without any plane configured. On Gen2 hardware the first
frame will be black and likely unnoticed, but on Gen3 hardware we end up
starting the display before the VSP compositor, which is more
noticeable.

To fix this, revert the order of the commit operations back, and handle
runtime PM requirements in the CRTC .atomic_begin() and .atomic_enable()
helper operation handlers.

the workaround to H3 ES1.x.

From an implementation point of view, move work around handling outside
of the rcar_du_dpll_divider() function by requesting a x2 DPLL output
frequency explicitly. The existing post-divider calculation mechanism
will then take care of dividing the clock by two automatically.

While at it, print a more useful debugging message to ease debugging

774e39ee35 drm/msm/mdp5: Set up runtime PM for MDSS
MDSS represents the top level wrapper that contains MDP5, DSI, HDMI and
other sub-blocks. W.r.t device heirarchy, it's the parent of all these
devices. The power domain of this device is actually tied to the GDSC
hw. When any sub-device enables its PD, MDSS's PD is also enabled.

The suspend/resume ops enable the top level clocks that end at the MDSS
boundary. For now, we're letting them all be optional, since the child
devices anyway hold a ref to these clocks.

Until now, we'd called a runtime_get() during probe, which ensured that
the GDSC was always on. Now that we've set up runtime PM for the children
devices, we can get rid of this hack.

Note: that the MDSS device is the platform_device in msm_drv.c. The
msm_runtime_suspend/resume ops call the funcs that enable/disable
the top level MDSS clocks. This is different from MDP4, where the
platform device created in msm_drv.c represents MDP4 itself. It would
have been nicer to hide these differences by adding new kms funcs, but
runtime PM needs to be enabled before kms is set up (i.e, msm_kms_init
is called).

0f379b79ab drm/msm/mdp5: Write to SMP registers even if allocations don't change
Requests for assigning/freeing SMP blocks by planes are collected during
the atomic check phase, and represented by mdp5_smp_state's 'assigned'
and 'released' members.

Once the atomic state is committed, these members are reset to 0,
indicating that the existing configuration satisfies all the planes.
Future atomic commits will copy the old mdp5_smp_state, and the 'assigned'
and 'released' members would be updated only if there was a change in
the plane configurations.

When we disable and re-enable display, we lose the values we wrote to the
SMP registers, but the code doesn't program the registers because there
isn't any change in mdp5_smp_state.

Fix this by writing to the registers irrespective of whether there was
a change in SMP state or not. We do this by keeping a cache of the
register values, and write them every time we commit a state.

d68fe15b18 drm/msm/mdp5: Use runtime PM get/put API instead of toggling clocks
mdp5_enable/disable calls are scattered all around in the MDP5 code.
Use the pm_runtime_get/put calls here instead, and populate the
runtime PM suspend/resume ops to manage the clocks.

About the overall design: MDP5 is a child of the top level MDSS
device. MDSS is also the parent to DSI, HDMI and other interfaces. When
we enable MDP5's power domain, we end up enabling MDSS's PD too. It is
only MDSS's PD that actually controlls the GDSC HW. Therefore, calling
runtime_get/put on the MDP5 device is like just requesting a vote to
enable/disable the GDSC.

Functionally, replacing the clock enable/disable calls with the RPM API
can result in the power domain (GDSC) state being toggled if no other
child isn't powered on. This can result in the register context being lost.
We make sure (in future commits) that code paths don't end up configuring
registers and then later lose state, resulting in a bad HW state.

For now, we've replaced each mdp5_enable/disable with runtime_get/put API.
We could optimize things later by removing runtime_get/put calls which
don't really need to be there. This could prevent unnecessary toggling of
the power domain and clocks.

8f93e043d0 drm/msm: gpu: don't abuse dma_alloc for non-DMA allocations
In zap_shader_load_mdt(), we pass a pointer to a phys_addr_t
into dmam_alloc_coherent, which the compiler warns about:

drivers/gpu/drm/msm/adreno/a5xx_gpu.c: In function 'zap_shader_load_mdt':
drivers/gpu/drm/msm/adreno/a5xx_gpu.c:54:50: error: passing argument 3 of 'dmam_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]

The returned DMA address is later passed on to a function that
takes a phys_addr_t, so it's clearly wrong to use the DMA
mapping interface here: the memory may be uncached, or the
address may be completely wrong if there is an IOMMU connected
to the device. What the code actually wants to do is to get
the physical address from the reserved-mem node. It goes through
the dma-mapping interfaces for obscure reasons, and this
apparently only works by chance, relying on specific bugs
in the error handling of the arm64 dma-mapping implementation.

The same problem existed in the "venus" media driver, which was
now fixed by Stanimir Varbanov after long discussions.

In order to make some progress here, I have now ported his
approach over to the adreno driver. The patch is currently
untested, and should get a good review, but it is now much
simpler than the original, and it should be obvious what
goes wrong if I made a mistake in the port.

bdab8e8b2b drm/msm: gpu: call qcom_mdt interfaces only for ARCH_QCOM
When compile-testing for something other than ARCH_QCOM,
we run into a link error:

a5xx_gpu.c:(.text.a5xx_hw_init+0x93c): undefined reference to `qcom_mdt_load'

There is already an #ifdef that tries to check for CONFIG_QCOM_MDT_LOADER,
but that symbol is only meaningful when building for ARCH_QCOM.

This adds a compile-time check for ARCH_QCOM, and clarifies the
Kconfig select statement so we don't even try it for other targets.

The check for CONFIG_QCOM_MDT_LOADER can then go away, which also
improves compile-time coverage and makes the code a little nicer
to read.

d4cea38ebb drm/msm/dsi: Calculate link clock rates with updated dsi->lanes
After the commit mentioned below, we start computing the byte and pixel
clocks (dsi_calc_clk_rate) in the DSI bridge's mode_set() op. The
calculation involves the number of DSI lanes being used by the
downstream bridge/panel.

If the downstream bridge/panel tries to change the number of DSI lanes
(as done in the ADV7533 driver) in its mode_set() op, then our DSI
host driver will not have the correct number of lanes when computing
byte/pixel clocks.

Fix this by delaying the clock rate calculation in the DSI bridge
enable path. In particular, compute the clock rates in
msm_dsi_host_get_phy_clk_req().

This fixes the DSI host error interrupts seen when we try to switch
between modes that require different number of lanes (4 to 3 lanes, or
vice versa) on db410c. The error interrupts occur since the byte/pixel
clock rates aren't according to what the DSI video mode timing engine
expects.

65e9310889 drm/msm: fix an integer overflow test
We recently added an integer overflow check but it needs an additional
tweak to work properly on 32 bit systems.

The problem is that we're doing the right hand side of the assignment as
type unsigned long so the max it will have an integer overflow instead
of being larger than SIZE_MAX.  That means the "sz > SIZE_MAX" condition
is never true even on 32 bit systems.  We need to first cast it to u64
and then do the math.

e6fc3b6855 drm: Plumb modifiers through plane init
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)
