28647b52ec drm/i915/guc: Don't try to create log runtime if there is no log
In case of GuC initialization failure we may continue with driver
load, but we wrongly assume that GuC is fully functional. This
leads to the BUG as we attempt to access non-existing log vma.

bf67ce62a0 drm/i915/guc: Don't forget to free GuC error log
We're freeing GuC error log in uc_fini_hw() that matches
corresponding uc_init_hw() but we missed the point that this
log object is copied on error path and in case of failure in
uc_init_hw() we will leak this object as uc_fini_hw() is
never called.

If we free this log object as part of the late uC cleanup, where
we also release other firmware objects, we can avoid this BUG:

Try to catch a bug we've seen in the wild where the shrinker purges the

b715a2f0c7 drm/i915/ppgtt: Pin page directories before allocation
Commit e2b763caa6 ("drm/i915: Remove bitmap tracking for used-pdpes")
believed that because it did not insert its freshly allocated page
directory into the pd tree, it was safe from the shrinker. I failed to
heed the lesson learnt from commit dd19674bac ("drm/i915: Remove bitmap
tracking for used-ptes") that we need to pin all the levels in the tree
before hitting the shrinker or else the shrinker may free an upper layer
as we proceed to allocate the tree. Thus leaving dangling pointers
everywhere and a GPF should we hit direct reclaim at just the wrong
moment.

225701fc20 drm/i915/icl: Set graphics mode register for gen11
This patch clears a single bit. The bit is 0 by default but expected
not to be set. Explicitly clearing the bit in this patch is intended
to indicate some thinking has occurred, and that we want this bit
cleared and we are not just excepting the default value.

We also stop setting GFX_RUN_LIST_ENABLE, which is correct since that
bit is gone.

5b364bec5c 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.

889230489b 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
4680816be3 ("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.

168fe32a07 Merge branch 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull poll annotations from Al Viro:
 "This introduces a __bitwise type for POLL### bitmap, and propagates
  the annotations through the tree. Most of that stuff is as simple as
  'make ->poll() instances return __poll_t and do the same to local
  variables used to hold the future return value'.

  Some of the obvious brainos found in process are fixed (e.g. POLLIN
  misspelled as POLL_IN). At that point the amount of sparse warnings is
  low and most of them are for genuine bugs - e.g. ->poll() instance
  deciding to return -EINVAL instead of a bitmap. I hadn't touched those
  in this series - it's large enough as it is.

  Another problem it has caught was eventpoll() ABI mess; select.c and
  eventpoll.c assumed that corresponding POLL### and EPOLL### were
  equal. That's true for some, but not all of them - EPOLL### are
  arch-independent, but POLL### are not.

  The last commit in this series separates userland POLL### values from
  the (now arch-independent) kernel-side ones, converting between them
  in the few places where they are copied to/from userland. AFAICS, this
  is the least disruptive fix preserving poll(2) ABI and making epoll()
  work on all architectures.

  As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
  it will trigger only on what would've triggered EPOLLWRBAND on other
  architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
  at all on sparc. With this patch they should work consistently on all
  architectures"

drm_encoder_slave is the old way to write bridge drivers, for i2c
bridges only. It's deprecated, and definitely should not be used in
new drivers. This has absolutely nothing to do with the new bridge
driver infrastructure implemented by drm_bridge.

What's even strange is that arcpgu doesn't even use any of this, it
really only wants a plain normal drm_encoder. Nuke all the surplus
real estate.

394676f05b drm/i915: Add WA for planes ending close to left screen edge
While running the kms_plane clipping test I noticed a similar problem to
the one described in Display WA #1175. In this case, similarly for
planes other than the cursor, with 1 or 3 pixels visible from the left
edge of the screen to the end of the plane and an odd plane X offset
used for clipping causes the same kind of underflow and display
corruption as described for WA #1175. Fix this in a similar way as that
WA rejecting planes ending <4 pixels from the left screen edge.

c322c64952 drm/i915: Add display WA #1175 for planes ending close to right screen edge
As described in the WA on GLK and CNL planes on the right edge of the
screen that have less than 4 pixels visible from the beginning of the
plane to the edge of the screen can cause FIFO underflow and display
corruption.

On GLK/CNL I could trigger the problem only if the plane was at the same
time also aligned to the top edge of the screen (after clipping) and
there were exactly 2 pixels visible from the start of the plane to the
right edge of the screen (so couldn't trigger it with 1 or 3 pixels
visible). Nevertheless, to be sure, I also applied the WA for these cases.

I also couldn't see any problem with the cursor plane and later Art
confirmed that it's not affected, so the WA is applied only for the
other plane types.

1c6ceeee6e drm/atomic: Fix memleak on ERESTARTSYS during non-blocking commits
During a non-blocking commit, it is possible to return before the
commit_tail work is queued (-ERESTARTSYS, for example).

Since a reference on the crtc commit object is obtained for the pending
vblank event when preparing the commit, the above situation will leave
us with an extra reference.

Therefore, if the commit_tail worker has not consumed the event at the
end of a commit, release it's reference.

Changes since v1:
- Also check for state->event->base.completion being set, to
  handle the case where stall_checks() fails in setup_crtc_commit().
Changes since v2:
- Add a flag to drm_crtc_commit, to prevent dereferencing a freed event.
  i915 may unreference the state in a worker.

75a655e0a2 drm/modes: Provide global mode_valid hook
Allow drivers to provide a device wide .mode_valid() hook in addition to
the already existing crtc/encoder/bridge/connector hooks. This can be
used to validate device/driver wide constraings without having to add
those to the other hooks. And since we call this hook also for user
modes later on in the modeset we don't have to worry about anything the
hook has already rejected.

I also have some further ideas for this hook. Eg. we could replace the
drm_mode_set_crtcinfo(HALVE_V) call in drm_mode_convert_umode()/etc.
with a driver specific variant via this hook. At least on i915 we would
like to pass CRTC_STEREO_DOUBLE to that function instead, and then
we could safely use the crtc_ timings in all our .mode_valid() hooks,
which would allow us to reuse those hooks for validating the
adjusted_mode during a modeset.

For connectors the issue is a bit more complicated as they can
be created/destroyed at runtime due to MST. So the problem is no

Single irq regression fix

0fd189a95f drm/nouveau: Move irq setup/teardown to pci ctor/dtor
For a while we've been having issues with seemingly random interrupts
coming from nvidia cards when resuming them. Originally the fix for this
was thought to be just re-arming the MSI interrupt registers right after
re-allocating our IRQs, however it seems a lot of what we do is both
wrong and not even nessecary.

This was made apparent by what appeared to be a regression in the
mainline kernel that started introducing suspend/resume issues for
nouveau:

        a0c9259dc4 (irq/matrix: Spread interrupts on allocation)

After this commit was introduced, we started getting interrupts from the
GPU before we actually re-allocated our own IRQ (see references below)
and assigned the IRQ handler. Investigating this turned out that the
problem was not with the commit, but the fact that nouveau even
free/allocates it's irqs before and after suspend/resume.

For starters: drivers in the linux kernel haven't had to handle
freeing/re-allocating their IRQs during suspend/resume cycles for quite
a while now. Nouveau seems to be one of the few drivers left that still
does this, despite the fact there's no reason we actually need to since
disabling interrupts from the device side should be enough, as the
kernel is already smart enough to know to disable host-side interrupts
for us before going into suspend. Since we were tearing down our IRQs by
hand however, that means there was a short period during resume where
interrupts could be received before we re-allocated our IRQ which would
lead to us getting an unhandled IRQ. Since we never handle said IRQ and
re-arm the interrupt registers, this would cause us to miss all of the
interrupts from the GPU and cause our init process to start timing out
on anything requiring interrupts.

So, since this whole setup/teardown every suspend/resume cycle is
useless anyway, move irq setup/teardown into the pci subdev's ctor/dtor
functions instead so they're only called at driver load and driver
unload. This should fix most of the issues with pending interrupts on
resume, along with getting suspend/resume for nouveau to work again.

As well, this probably means we can also just remove the msi rearm call
inside nvkm_pci_init(). But since our main focus here is to fix
suspend/resume before 4.15, we'll save that for a later patch.

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!).

70deeaddc6 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.

Apparently SKL/KBL/CFL need some manual help to get the
programmed HDMI vswing to stick. Implement the relevant
workaround (display w/a #1143).

Note that the relevant chicken bits live in a transcoder register
even though the bits affect a specific DDI port rather than a
specific transcoder. Hence we must pick the correct transcoder
register instance based on the port rather than based on the
cpu_transcoder.

Also note that for completeness I included support for DDI A/E
in the code even though we never have HDMI on those ports.

c60c4af36d drm/zte: Use drm_mode_get_hv_timing() to populate plane clip rectangle
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

Note that this replaces crtc_state->adjusted_mode usage with
crtc_state->mode. The latter is the correct choice since that's the
mode the user provided and it matches the plane crtc coordinates

Once everyone agrees on this we can move the clip handling into

c1beabcf14 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.)

v2: Include some notes on where I plucked the numbers from.

c0cfb10d9e 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.

drm/sun4i: backend: Make sure we don't have a commit pending
If we try to read the backend registers while it fetches the new values, we
end up with the value of some random register instead of the one we asked
for.

In order to prevent that, let's make sure that the very first thing we do
during our atomic modesetting is to let the commit bit come to a rest.

We don't have to worry about anything else since the only time we will
trigger a new transaction is during the atomic_commit which comes much
later.

drm/sun4i: backend: Add a custom atomic_check for the frontend
Now that we have everything in place, we can start enabling the frontend.
This is more difficult than one would assume since there can only be one
plane using the frontend per-backend.

We therefore need to make sure that the userspace will not try to setup
multiple planes using it, since that would be impossible. In order to
prevent that, we can create an atomic_check callback that will check that
only one plane will effectively make use of the frontend in a given
configuration, and will toggle the switch in that plane state so that the
proper setup function can do their role.

drm/sun4i: backend: Wire in the frontend
Now that we have a driver, we can make use of it. This is done by
adding a flag to our custom plane state that will trigger whether we should
use the frontend on that particular plane or not.

The rest is just plumbing to set up the backend to not perform the DMA but
receive its data from the frontend.

Note that we're still not making any use of the frontend itself, as no one
is setting the flag yet.

841b5ed7aa drm/i915/cnl: Add Port F definition.
Some Cannonlake SKUs will come with a full split between
port A and port E. This will be called port F although it
is not a 6th port, but only a split.

Note this patch alone is not sufficient for port F enabling,
it's just the first step.

v2: Fix size of dvo_ports found by Ander.
v3: Adding missing cases from intel_bios.c for Port_F
v4: Adding other missing cases and fix the commit message.
v5: Rebase on top of display headers rework.
v6 (from Paulo): improve commit message, bikeshed bit definitions.

77064e2eb8 drm/i915: Add CCS capability for sprites
Allow sprites to scan out compressed framebuffers.

Since different platforms have a different set of planes that
support CCS let's add a small helper to determine whether a
specific plane supports CCS or not. Currently that information
is spread around in many places, and not all the pieces of
code even agree with each other.

In addition to allowing sprites to scan out compressed fbs,
the other fix here is that we stop rejecting them on pipe C
on CNL.

3019062905 drm/i915: Ignore TMDS clock limit for DP++ when EDID override is set
4K modes testing by using dummy EDID data has never been working
properly on boxes with DP++ (dual-mode) adaptors. The reason for
this is that those modes got pruned during hdmi mode validation.
intel_hdmi_mode_valid returns CLOCK_HIGH because the pixel clock
reported by the 4k mode is higher than dual port TMDS clock limit.

However 4k injection does work properly on machines that don't have
DP++ adapters because the mode is never validated against the DP++
TMDS clock limit.

v2: Don't detect the DP++ limits when we're testing using overridden
    EDIDs. Make sure to check for the override condition after
    respecting the value of drm_dp_dual_mode_detect (Jani Nikula).

e062a01e6d drm/nouveau/bar/gk20a: Avoid bar teardown during init
Commit bbb163e189 ("drm/nouveau/bar: implement bar1 teardown")
introduced add a teardown helper function for BAR1. During
initialisation of the Nouveau, initially all the teardown helpers are
called once, before calling their init counterparts. For gk20a, after
the BAR1 teardown function is called, the device is hanging during the
initialisation of the FB sub-device. At this point it is unclear why
this is happening and this is still under investigation. However, this
change is preventing Tegra124 devices from booting when Nouveau is
enabled. To allow Tegra124 to boot, remove the teardown helper for
gk20a.

This is based upon a previous patch by Guillaume Tucker but limits
the workaround to only gk20a GPUs.

35fe703c31 drm/i915/guc: Change values for i915_guc_log_control
Today we have format mismatch between read/write operations
of i915_guc_log_control entry. For read we return (0, 1..4)
that represents disable/verbosity levels, but for write we
force user to follow internal structure format (0,1,9,11,13).
Let's hide internals from the user and accept same values
as we support for read and related guc_log_level modparam.

e9af4ea2b9 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.

b6c51c3e28 drm/i915: Add tracking for CDCLK bypass frequency
The CDCLK bypass frequency can vary on upcoming platforms, so prepare
for that now by tracking its value in the CDCLK state.

Currently on BDW+ the bypass frequency is always the reference clock and
I didn't bother with earlier platforms since it's not all that clear
what's the bypass clock on those.

I also didn't bother adding support for changing this frequency, since
atm I don't see any need for it.

When testing that the timeout fired, we need to be sure we have waited
just long enough for the timeout to have occurred and for the softirq
(on another cpu) to have completed. Sleeping for an arbitrary amount is
prone to error, so wait for the timeout instead and complain if it was
too late.

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.

341a0ffcea 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.

Tvrtko noticed that the comments describing the interaction of RCU and
the deferred worker for freeing drm_i915_gem_object were a little
confusing, so attempt to bring some sense to them.

fd2cb71bbc drm/bridge/synopsys: dsi: handle endianness correctly in dw_mipi_dsi_write()
We're filling the "remainder" word with little-endian data, then writing
it out to IO registers with endian-correcting writel(). That probably
won't work on big-endian systems.

Let's mark the "remainder" variable as LE32 (since we fill it with
memcpy()) and do the swapping explicitly.

Some of this function could be done more easily without memcpy(), but
the unaligned "remainder" case is a little hard to do without
potentially overrunning 'tx_buf', so I just applied the same solution in
all cases (memcpy() + le32_to_cpu()).

Tested only on a little-endian system.

ad95dc86e6 drm/bridge/synopsys: dsi: use common mipi_dsi_create_packet()
This takes care of 2 TODOs in this driver, by using the common DSI
packet-marshalling code instead of our custom short/long write code.
This both saves us some duplicated code and gets us free support for
command types that weren't already part of our switch block (e.g.,
MIPI_DSI_GENERIC_LONG_WRITE).

The code logic stays mostly intact, except that it becomes unnecessary
to split the short/long write functions, and we have to copy data a bit
more.

Along the way, I noticed that loop bounds were a little odd:

	while (DIV_ROUND_UP(len, pld_data_bytes))

This really was just supposed to be 'len != 0', so I made that more
clear.

Tested on RK3399 with some pending refactoring patches by Nickey Yang,
to make the Rockchip DSI driver wrap this common driver.

beacbd1615 drm/i915: Use our singlethreaded wq for freeing objects
As freeing the objects require serialisation on struct_mutex, we should
prefer to use our singlethreaded driver wq that is dedicated to work
requiring struct_mutex (hence serialised).The benefit should be less
clutter on the system wq, allowing it to make progress even when the
driver/struct_mutex is heavily contended.

4488496d58 drm/i915: Fix deadlock in i830_disable_pipe()
i830_disable_pipe() gets called from the power well code, and thus
we're already holding the power domain mutex. That means we can't
call plane->get_hw_state() as it will also try to grab the
same mutex and will thus deadlock.

Replace the assert_plane() calls (which calls ->get_hw_state()) with
just raw register reads in i830_disable_pipe(). As a bonus we can
now get a warning if plane C is enabled even though we don't even
expose it as a drm plane.

23ac127328 drm/i915: Redo plane sanitation during readout
Unify the plane disabling during state readout by pulling the code into
a new helper intel_plane_disable_noatomic(). We'll also read out the
state of all planes, so that we know which planes really need to be
diabled.

Additonally we change the plane<->pipe mapping sanitation to work by
simply disabling the offending planes instead of entire pipes. And
we do it before we otherwise sanitize the crtcs, which means we don't
have to worry about misassigned planes during crtc sanitation anymore.

Two important fixes for vmwgfx.
The off-by-one fix could cause a malicious user to potentially crash the
kernel.
The framebuffer map cache fix can under some circumstances enable a user to
read from or write to freed pages.

9be712ef46 drm/tegra: Changes for v4.16-rc1
The bulk of these changes are preparation work and addition of support
 for Tegra186. Currently only HDMI output (the primary output on Jetson
 TX2) is supported, but the hardware is also capable of doing DSI and
 DisplayPort.
 
 Tegra DRM now also uses the atomic commit helpers instead of the open-
 coded variant that was only doing half its job. As a bit of a byproduct
 of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos
 property support.
 
 Along the way there are also a few patches to clean up a few things and
 fix minor issues.

2fa6d6cdaf drm/nouveau: deprecate pci_get_bus_and_slot()
pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.

Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().

Replace pci_get_bus_and_slot() with pci_get_domain_bus_and_slot()
and extract the domain number from
1. struct pci_dev
2. struct pci_dev through drm_device->pdev
3. struct pci_dev through fb->subdev->drm_device->pdev

Getting ready to remove pci_get_bus_and_slot() function in favor of

Add domain parameter to CDV_MSG_READ32, CDV_MSG_WRITE32, MRST_MSG_READ32,
MRST_MSG_WRITE32, MDFLD_MSG_READ32, MDFLD_MSG_WRITE32.

Extract pci_dev from struct drm_device and use pdev to find the domain
number while calling pci_get_domain_bus_and_slot().
