b8ec759e6f drm/i915/hsw: add missing disabled EUs registers reads
It turns out that HSW has a register that tells us how many EUs are
disabled per half-slice (roughly a similar notion to subslice). We
didn't read those registers so far as most userspace drivers didn't
need those values prior to Gen8, but an internal library would like to
have access to this.

Since we already have the getparam interface, there is no harm in
exposing this.

e61e0f51ba drm/i915: Rename drm_i915_gem_request to i915_request
We want to de-emphasize the link between the request (dependency,
execution and fence tracking) from GEM and so rename the struct from
drm_i915_gem_request to i915_request. That is we may implement the GEM
user interface on top of requests, but they are an abstraction for
tracking execution rather than an implementation detail of GEM. (Since
they are not tied to HW, we keep the i915 prefix as opposed to intel.)

In short, the spatch:
@@

@@
- struct drm_i915_gem_request
+ struct i915_request

A corollary to contracting the type name, we also harmonise on using
'rq' shorthand for local variables where space if of the essence and
repetition makes 'request' unwieldy. For globals and struct members,
'request' is still much preferred for its clarity.

1c9b6b133e drm/i915/fbc: Use PLANE_HAS_FENCE to determine if the plane is fenced
Rather than trusting the cached value of plane_state->vma->fence to
imply whether the plane_state itself holds a reference on the
framebuffer's fence, use the information provided in the
plane_state->flags (PLANE_HAS_FENCE). Note that we still assume that FBC
is entirely bounded by the plane_state active life span; it's not clear
if that is a safe assumption.

5935485f8e drm/i915: Move the policy for placement of the GGTT vma into the caller
Currently we make the unilateral decision inside
i915_gem_object_pin_to_display() where the VMA should resided (inside
the fence and mappable region or above?). This is not our decision to
make as it impacts on how the display engine can use the resulting
scanout object, and it would rather instruct us where to place the VMA so
that it can enable the features it wants. As such, make the pin flags an
argument to i915_gem_object_pin_to_display() and control them from
intel_pin_and_fence_fb_obj()

Whilst taking control of the mapping for ourselves, start tracking how
we use it to avoid trying to free a fence we never claimed:

c154d1e0aa drm/i915: Set the primary plane pipe select bits on gen4
i965 and g4x still have the pipe select bits in the plane control
registers, they're just hardcoded to select a specific pipe. However
plane C on i965 can still move between the pipes, thus we should
program the pipe select bits on i965 if we want to expose plane C
some day.

Since there is no harm in programming the bits on any plane on
i965/g4x let's just always set them. This will also make our
pre-computed register value match what the hardware register
would read, should we want to cross check the two.

G4x cursor control registers still allow us to write to the pipe select
bits even though cursors are supposed to be fixed to a specific pipe.
Bspec tells us that we should only ever write 0 to these bits. Let's
follow that recommendation. On ilk+ the bits become hardwired to 0.

Also looks like ICL repurposes these bits for some other use, so
we had better stop setting them to bogus values there.

aa81e2c334 drm/i915: Assert that we don't overflow frontbuffer tracking bits
Add some compile time assrts to the frontbuffer tracking to make sure
that we have enough bits per pipe to cover all the planes, and that we
have enough total bits to cover all the planes across all pipes.

We'll ignore any potential clash between the overlay bit and the
plane bits because that will allow us to keep using a total of 32
bits for the foreseeable future.

While at it change the macros to use BIT() and GENMASK(). The latter
gets rid of the hardcoded 0xff and thus means we can change the
number of bits per pipe by just changing
INTEL_FRONTBUFFER_BITS_PER_PIPE.

c9c7047154 drm/i915: Track number of pending freed objects
During igt, we frequently call into the driver to reset both HW and
driver state (idling the device, waiting for it to become idle and
freeing off old objects) to ensure that we start each test/subtest/pass
from known state. This process incurs an RCU barrier or two to ensure
that any such pending frees are indeed flushed before we return.
However, unconditionally waiting on the RCU barrier adds needless delay
to many callers, which adds up to several seconds when repeated thousands
of times. We can skip the rcu_barrier() if by tracking how many outstanding
frees we have, we know there are none.

The same path is used along suspend, where we may be able to save the
unconditional RCU barrier.

To put it into perspective with a completely meaningless
microbenchmark, igt/gem_sync/idle is improved from 50ms to 30us on bdw.

needs to be moved for the next execbuf), then we need to clear the
persistent tracking state we setup for this execbuf.

Fixes: c7c6e46f913b ("drm/i915: Convert execbuf to use struct-of-array packing for critical fields")
Testcase: igt/gem_fenced_exec_thrash/no-spare-fences-busy*

2e4a5b2588 drm/i915: Prune gen8_gt_irq_handler
The compiler is not automatically caching the i915->regs address inside
a register and emitting a load for every mmio access. For simple
functions like gen8_gt_irq_handler that are already using the raw
accessors, we can open-code them for substantial savings:

add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-83 (-83)

f0fd96f546 drm/i915: Track GT interrupt handling using the master iir
Keep the master iir and use it to reduce the number of reads and writes
to the GT iir array, i.e. only the bits marked as set by the master iir
are valid inside GT iir array and will be handled during the interrupt.

acb79148dc drm/i915: Remove WARN_ONCE for failing to pm_runtime_if_in_use
As the driver is called to handle circumstances beyond it's control, we
cannot assume that the pm_runtime core is happy to see us. For example,
if we are called from shrink_slab to free up our pages during suspend,
rpm may be disabled and pm_runtime_if_in_use() decides to fail with
-EINVAL rather than simply say no. This is expected to happen, so don't
warn.  For example,

41e1bd5648 drm: intel_dpio_phy: fix kernel-doc comments at nested struct
The in-lined comments for channel.port doesn't follow the syntax
described at kernel-doc document, causing the following warning:

	$ ./scripts/kernel-doc -none drivers/gpu/drm/i915/intel_dpio_phy.c
	drivers/gpu/drm/i915/intel_dpio_phy.c:154: warning: Function parameter or member 'channel.port' not described in 'bxt_ddi_phy_info'

While the best would be for the Kernel to deduce that from the
context, supporting it is not trivial. So, let's just stick with
the existing syntax.

[Jani: depends on "scripts: kernel-doc: support in-line comments on
nested structs/unions" to actually fix the warning.]

339ccd35b4 drm/i915: Assert that we always complete a submission to guc/execlists
The continual resubmission model for execlists (and emulated over guc)
requires that we keep feeding requests into the HW in order to generate
more CS interrupts to drain the rest of the queue. Add a couple of
asserts to ensure that we don't skip a cycle and come to a grinding
halt.

c0a51fd07b drm: move read_domains and write_domain into i915
i915 is the only driver using those fields in the drm_gem_object
structure, so they only waste memory for all other drivers.

Move the fields into drm_i915_gem_object instead and patch the i915 code
with the following sed commands:

sed -i "s/obj->base.read_domains/obj->read_domains/g" drivers/gpu/drm/i915/*.c drivers/gpu/drm/i915/*/*.c
sed -i "s/obj->base.write_domain/obj->write_domain/g" drivers/gpu/drm/i915/*.c drivers/gpu/drm/i915/*/*.c

Change is only compile tested.

2e8bf223d8 drm/i915: Estimate and update missed vblanks.
The frame counter may have got reset between disabling and enabling vblank
interrupts due to DMC putting the hardware to DC5/6 states if PSR was
active. The frame counter could also have stalled if PSR was active in case
there was no DMC. The frame counter resetting has a user visible impact
of screen freezes.

Make use of drm_vblank_restore() to compute missed vblanks for the duration
in which vblank interrupts were disabled and update the vblank counter with
this value as diff. There's no need to check if PSR was actually active in
the interrupt disabled duration, so simplify the check to a feature check.

Enabling vblank interrupts wakes up the hardware from DC5/6 and prevents it
from going back again as long as the there are pending interrupts. So, we
don't have to explicity disallow DC5/6 after enabling vblank interrupts to
keep the counter running.

This change is not applicable to CHV, as enabling interrupts does not
prevent the hardware from activating PSR.

v2: Added comments(Rodrigo) and rewrote commit message.

ccf74400da drm/i915/cnl: Remove alpha_support protection
We now have a stable cnl on our CI and it seems mostly
green without big risks of blank screen or anything
blowing up on linux installations in the future.

As a reminder i915.alpha_support was created to protect
future linux installation's iso images that might contain a
kernel from the enabling time of the new platform. Without this
protection most of linux installation was recommending
nomodeset option during installation that was getting stick
there after installation.

Specifically, alpha support says nothing about the development
state of the hardware, and everything about the state of the
driver in a kernel release.

This is semantically no different from the old
preliminary_hw_support flag, but the old one was all too often
interpreted as (preliminary hw) support instead of the intended
(preliminary) hw support, and it was misleading for everyone.
Hence the rename.

v2: Fix the typos and include more history about the parameter
rename on commit message. (Jani)

b6a88e4a80 drm/i915: Fix rsvd2 mask when out-fence is returned
GENMASK_ULL wants the high bit of the mask first. The current value
cancels the in-fence when an out-fence is returned.

Fixes: fec0445caa273 ("drm/i915: Support explicit fencing for execbuf")
Testcase: igt/gem_exec_fence/keep-in-fence*
