The trouble here is that it does multiple atomic commits under one
drm_modeset_lock_all, which breaks the behind-the-scenes acquire
context magic that function pulls off. It's much better to have one
overall atomic commit. That we still have multiple atomic commits
prevents us from adding some pretty useful debug checks to the atomic
machinery.
Hence it is really a bad idea to call the legacy
drm_crtc_force_disable_all() function. There's 2 atomic drivers using
this still, nouveau and tinydrm. To fix this, introduce a new
drm_atomic_helper_shutdown() by extracting the code from i915.
While at it improve kernel-doc and catch future offenders by
sprinkling a WARN_ON into the legacy function. We should probably move
those into the legacy modeset helpers, too ...
v2: Make it compile on arm drivers too (Noralf).
v3: Correct kerneldoc to point at _disable_all().

When we wedge the device, we override engine->submit_request with a nop
to ensure that all in-flight requests are marked in error. However, igt
would like to unwedge the device to test -EIO handling. This requires us
to flush those in-flight requests and restore the original
engine->submit_request.

v3: Split new vfunc to a separate patch.
v4: Make the wait interruptible -- the third party fences we wait upon
may be indefinitely broken, so allow the reset to be aborted.

I915_RESET_IN_PROGRESS is being used for both signaling the requirement
to i915_mutex_lock_interruptible() to avoid taking the struct_mutex and
to instruct a waiter (already holding the struct_mutex) to perform the
reset. To allow for a little more coordination, split these two meaning
into a couple of distinct flags. I915_RESET_BACKOFF tells
i915_mutex_lock_interruptible() not to acquire the mutex and

Instead of calling intel_guc_init() and intel_huc_init() one by one this
patch introduces intel_uc_init_fw() function that calls them both.
Called functions are renamed accordingly.
Trying to have subject_verb_object ordering and more descriptive names,
the intel_huc_init() and intel_guc_init() functions are renamed.
For guc_init():
* `intel_guc` is the subject, so those functions now take intel_guc
structure, instead of the dev_priv
* init is the verb
* fw is the object which better describes the function's role
huc_init() change follows the same reasoning.
v2: settle on intel_uc_fetch_fw name (M. Wajdeczko)
v3: yet another rename - intel_uc_init_fw (J. Lahtinen)

There's really not a reason afaics that we can't just clean up
everything at the end, in the terminal postclose hook: Since this is
closing a file descriptor we know no one else can have a reference or
a thread doing something with that drm_file except the close code.
Ordering shouldn't matter, as long as we don't kfree before we clean
stuff up.
In the past this was more relevant when drivers still had to track and
clean up pending drm events, but that's all done by the core now.

Use I915_{READ,WRITE}_FW() for updating the DSPARB registers on
VLV/CHV. This is less expesive as we can grab the uncore.lock across
the entire sequence of reads and writes instead of each register
access grabbing it.
This also allows us to eliminate the dsparb lock entirely as the
uncore.lock now effectively protects the contents of the DSPARB
registers.

We don't use the error return for anything other than reporting and
logging that there is no VBT. We can pull the logging in the function,

the bit in dev_priv, and using it where it's needed, instead of using
the error return.

First slice of drm-misc-next for 4.12:
Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail

small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state
Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
official, still an experiment, but definitely not complete fail and
better to avoid confusion. We kinda screwed that up with drm-misc a
bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over
This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
This patch makes the I915_PARAM_HAS_EXEC_CONSTANTS getparam return 0
(indicating the optional feature is not supported), and makes execbuf
always return -EINVAL if the flags are used.
Apparently, no userspace ever shipped which used this optional feature:
I checked the git history of Mesa, xf86-video-intel, libva, and Beignet,
and there were zero commits showing a use of these flags. Kernel commit
72bfa19c8d apparently introduced the feature prematurely. According
to Chris, the intention was to use this in cairo-drm, but "the use was
broken for gen6", so I don't think it ever happened.
'relative_constants_mode' has always been tracked per-device, but this
has actually been wrong ever since hardware contexts were introduced, as
the INSTPM register is saved (and automatically restored) as part of the
render ring context. The software per-device value could therefore get
out of sync with the hardware per-context value. This meant that using
them is actually unsafe: a client which tried to use them could damage
the state of other clients, causing the GPU to interpret their BO
offsets as absolute pointers, leading to bogus memory reads.
These flags were also never ported to execlist mode, making them no-ops
on Gen9+ (which requires execlists), and Gen8 in the default mode.
On Gen8+, userspace can write these registers directly, achieving the
same effect. On Gen6-7.5, it likely makes sense to extend the command
parser to support them. I don't think anyone wants this on Gen4-5.
Based on a patch by Dave Gordon.
v3: Return -ENODEV for the getparam, as this is what we do for other
obsolete features. Suggested by Chris Wilson.

"This is the main drm pull request for v4.11.
Nothing too major, the tinydrm and mmu-less support should make
writing smaller drivers easier for some of the simpler platforms, and
there are a bunch of documentation updates.
Intel grew displayport MST audio support which is hopefully useful to
people, and FBC is on by default for GEN9+ (so people know where to
look for regressions). AMDGPU has a lot of fixes that would like new
firmware files installed for some GPUs.
Other than that it's pretty scattered all over.

here is the update of sound bits for 4.11: again at this time, no big
changes in ALSA and ASoC core but only cosmetic changes like
consitifaction. Meanwhile, quite a lot of developments are seen in
a few driver side.
ALSA Core:
- Clean up, consitification of some ops
HD-audio:
- A slight behavior change of single_cmd option
- Quirks for AmigaOne X1000, Samsung Ativ Book 8, Dell AiO, ALC221 HP,
and fixes for Lewisburg controller
- Realtek ALC299, ALC1220 codecs
Others:
- USB-audio: Tascam US-16x08 DSP mixer quirk
- Intel HDMI LPE audio support for Baytrail / Cherrytrail; this
contains some updates in drm/i915 for the new platform binding
ASoC:
- Lots of updates in Intel drivers, mostly for DisplayPort and HDMI
on Skylake and onwards, as well as more Baytrail / Cherrytrail
boards support
- Channel mapping support for HDMI
- Support for AllWinner A31 and A33, Everest Semiconductor ES8328,

Merge tag 'v4.10-rc8' into drm-next
Linux 4.10-rc8
Backmerge Linus rc8 to fix some conflicts, but also
to avoid pulling it in via a fixes pull from someone.
Once upon a time before we had automated GPU state capture upon hangs,
we had intel_gpu_dump. Now we come almost full circle and reinstate that
view of the current GPU queues and registers by using the error capture
facility to snapshot the GPU state when debugfs/.../i915_gpu_info is
opened - which should provided useful debugging to both the error
capture routines (without having to cause a hang and avoid the error
state being eaten by igt) and generally.
v2: Rename drm_i915_error_state to i915_gpu_state to alleviate some name
collisions between the error state dump and inspecting the gpu state.

As i915_gem_reset_finish() undoes the steps from
i915_gem_reset_prepare() to leave the system in a fully-working state,
e.g. to be able to free the breadcrumb signal threads, make sure that we
always call it even on the error path.

We may need to keep our memory management alive after we have unloaded
the physical pci device. For example, if we have exported an object via
dmabuf, that will keep the device around but the pci device may be
removed before the dmabuf itself is released, use of the pci hardware
will be revoked, but the memory and object management needs to persist
for the dmabuf.

This adds a file in i915's debugfs directory that allows userspace to
manually control HPD storm detection. This is mainly for hotplugging
tests, where we might want to test HPD storm functionality or disable
storm detection to speed up hotplugging tests without breaking anything.
Changes since v1:
- Make HPD storm interval configurable
- Misc code cleanup

i915 is pretty much feature complete. Support for atomic i915-specific
connector properties is still missing; those properties can (for now)
only be set through the legacy ioctl.
ILK style watermarks and gen9+ watermarks are handled atomically,
and nonblocking modesets work. FBC has also been made to work with
atomic.
gen4x- and vlv/chv watermarks still need to be fixed, so disable atomic
by default there for now.
Flip the switch!!

Currently we do a reset prepare/finish around the call to reset the GPU,
but it looks like we need a later stage after the hw has been
reinitialised to allow GEM to restart itself. Start by splitting the 2
GEM phases into 3:
prepare - before the reset, check if GEM recovered, then stop GEM
reset - after the reset, update GEM bookkeeping
finish - after the re-initialisation following the reset, restart GEM

too coarse as it does not distinguish between exclusive ownership of the

Apparently there are machines out there with Skylake CPU and KabyPoint
PCH. Judging from our driver code, there doesn't seem to be any code
paths that would do anything different between SunrisePoint and
KabyPoint PCHs, so it would seem okay to accept the combo without
warnings.

Previously intel_gvt_init() was called very early even before
MMIO initialization which had several drawbacks:
- Have to handle MMIO access for initial MMIO state dump if golden
state firmware is not available
- Hypervisor detection should depend on pvinfo only instead of detecting
hypervisor status.
- Don't know hw resource size e.g aperture, ggtt size to determine
for vGPU type, etc.
This trys to move intel_gvt_init() call late after required info
has already been initialized for GVT host.

Apparently there are machines out there with Skylake CPU and KabyPoint
PCH. Judging from our driver code, there doesn't seem to be any code
paths that would do anything different between SunrisePoint and
KabyPoint PCHs, so it would seem okay to accept the combo without
warnings.

We may keep the crtc's enabled when userspace unsets all framebuffers but
keeps the crtc active. This exposes a WARN in fbc_global disable, and
a lot of bugs in our hardware readout code. Solve this by disabling

Userspace is faced with a dilemma. The kernel requires implicit fencing
to manage resource usage (we always must wait for the GPU to finish
before releasing its PTE) and for third parties. However, userspace may
wish to avoid this serialisation if it is either using explicit fencing
between parties and wants more fine-grained access to buffers (e.g. it
may partition the buffer between uses and track fences on ranges rather
than the implicit fences tracking the whole object). It follows that
userspace needs a mechanism to avoid the kernel's serialisation on its
implicit fences before execbuf execution.
The next question is whether this is an object, execbuf or context flag.
Hybrid users (such as using explicit EGL_ANDROID_native_sync fencing on
shared winsys buffers, but implicit fencing on internal surfaces)
require a per-object level flag. Given that this flag need to be only
set once for the lifetime of the object, this reduces the convenience of
having an execbuf or context level flag (and avoids having multiple
pieces of uABI controlling the same feature).
Incorrect use of this flag will result in rendering corruption and GPU
hangs - but will not result in use-after-free or similar resource
tracking issues.
Serious caveat: write ordering is not strictly correct after setting
this flag on a render target on multiple engines. This affects all
subsequent GEM operations (execbuf, set-domain, pread) and shared
dma-buf operations. A fix is possible - but costly (both in terms of
further ABI changes and runtime overhead).

Signed-off-by: Jani Nikula <jani.nikula@intel.com>
The GPU may be in an unknown state following resume and module load. The
previous occupant may have left contexts loaded, or other dangerous
state, which can cause an immediate GPU hang for us. The only save
course of action is to reset the GPU prior to using it - similarly to
how we reset the GPU prior to unload (before a second user may be
affected by our leftover state).
We need to reset the GPU very early in our load/resume sequence so that
any stale HW pointers are revoked prior to any resource allocations we
make (that may conflict).
A reset should only be a couple of milliseconds on a slow device, a cost
we should easily be able to absorb into our initialisation times.

In order to reset the GPU early on in the module load sequence, we need
to allocate the basic engine structs (to populate the mmio offsets etc).
Currently, the engine initialisation allocates both the base struct and
also allocate auxiliary objects, which depend upon state setup quite
late in the load sequence. We split off the allocation callback for
later and allow ourselves to allocate the engine structs themselves
early.

This patch will allow for getparams to return the status of the HuC.
As the HuC has to be validated by the GuC this patch uses the validated
status to show when the HuC is loaded and ready for use. You cannot use
the loaded status as with the GuC as the HuC is verified after it is
loaded and is not usable until it is verified.
v2: removed the forewakes as the registers are already force-woken.

v3: rebased on top of drm-tip. Removed any reference to intel_huc.h
v4: rebased. Rename I915_PARAM_HAS_HUC to I915_PARAM_HUC_STATUS.
Remove intel_is_huc_valid() since it is used only in one place.
Put the case of I915_PARAM_HAS_HUC() in the right place.
