320d41b33a drm/i915: Extract ilk_lut_10()
Extract a helper to calculate the ILK+ 10bit gamma LUT entry.
It's already duplicated twice, and soon we'll have more.

59f9e9cab3 drm/i915: Skip modeset for cdclk changes if possible
If we have only a single active pipe and the cdclk change only requires
the cd2x divider to be updated bxt+ can do the update with forcing a full
modeset on the pipe. Try to hook that up.

v2:
- Wait for vblank after an optimized CDCLK change.
- Avoid optimization if the pipe needs a modeset (or was disabled).
- Split CDCLK change to a pre/post plane update step.
v3:
- Use correct version of CDCLK state as old state. (Ville)
- Remove unused intel_cdclk_can_skip_modeset()
v4:
- For consistency call intel_set_cdclk_post_plane_update() only during
  modesets (and not fastsets).
v5:
- Remove the logic to update the CD2X divider on-the-fly on ICL, since
  only a divider of 1 is supported there. Clint also noticed that the
  pipe select bits in CDCLK_CTL are oddly defined on ICL, it's not clear
  yet whether that's only an error in the specification.

48d9f87ddd drm/i915: Save the old CDCLK atomic state
The old state will be needed by an upcoming patch to determine if the
commit increases or decreases CDCLK, so move the old state to the atomic
state (while keeping the new one in dev_priv). cdclk.logical and
cdclk.actual in the atomic state isn't used atm anywhere after the
atomic check phase, so this should be safe.

v2:
- Use swap() instead of opencoding it. (Ville)

7881e60575 drm/i915: Only emit one semaphore per request
Ideally we only need one semaphore per ring to accommodate waiting on
multiple engines in parallel. However, since we do not know which fences
we will finally be waiting on, we emit a semaphore for every fence. It
turns out to be quite easy to trick ourselves into exhausting our
ringbuffer causing an error, just by feeding in a batch that depends on
several thousand contexts.

Since we never can be waiting on more than one semaphore in parallel
(other than perhaps the desire to busywait on multiple engines), just
pick the first fence for our semaphore. If we pick the wrong fence to
busywait on, we just miss an opportunity to reduce latency.

An adaption might be to use sched.flags as either a semaphore counter,
or to track the first busywait on each engine, converting it back to a
single use bit prior to closing the request.

v2: Track first semaphore used per-engine (this caters for our basic
igt that semaphores are working).

b01720bfcd drm/i915: Prefault before locking pages in shmem_pwrite
If the user passes in a pointer to a GGTT mmaping of the same buffer
being written to, we can hit a deadlock in acquiring the shmemfs page
(once as the write destination and then as the read source).

We can reduce (but not eliminate!) the chance of this happening by
faulting the user_data before we take the page lock in
pagecache_write_begin(). One way to eliminate the potential recursion
here is by disabling pagefaults for the copy, and handling the fallback
to use an alternative method -- so convert to use kmap_atomic (which
should disable preemption and pagefaulting for the copy) and report
ENODEV instead of EFAULT so that our caller tries again with a different
copy mechanism -- we already check that the page should have been
faultable so a false negative should be rare.

805446c834 drm/i915: Introduce concept of a sub-platform
Concept of a sub-platform already exist in our code (like ULX and ULT
platform variants and similar),implemented via the macros which check a
list of device ids to determine a match.

With this patch we consolidate device ids checking into a single function
called during early driver load.

A few low bits in the platform mask are reserved for sub-platform
identification and defined as a per-platform namespace.

At the same time it future proofs the platform_mask handling by preparing
the code for easy extending, and tidies the very verbose WARN strings
generated when IS_PLATFORM macros are embedded into a WARN type
statements.

v2: Fixed IS_SUBPLATFORM. Updated commit msg.
v3: Chris was right, there is an ordering problem.

v4:
 * Catch-up with new sub-platforms.
 * Rebase for RUNTIME_INFO.
 * Drop subplatform mask union tricks and convert platform_mask to an
   array for extensibility.

v5:
 * Fix subplatform check.
 * Protect against forgetting to expand subplatform bits.
 * Remove platform enum tallying.
 * Add subplatform to error state. (Chris)
 * Drop macros and just use static inlines.
 * Remove redundant IRONLAKE_M. (Ville)

v6:
 * Split out Ironlake change.
 * Optimize subplatform check.
 * Use __always_inline. (Lucas)
 * Add platform_mask comment. (Paulo)
 * Pass stored runtime info in error capture. (Chris)

v7:
 * Rebased for new AML ULX device id.
 * Bump platform mask array size for EHL.
 * Stop mentioning device ids in intel_device_subplatform_init by using
   the trick of splitting macros i915_pciids.h. (Jani)
 * AML seems to be either a subplatform of KBL or CFL so express it like
   that.

v8:
 * Use one device id table per subplatform. (Jani)

ee8efa8079 drm/i915: Check domains for userptr on release
When we return pages to the system, we release control over them and
should defensively return them to the CPU write domain so that we catch
any external writes on reacquiring them (e.g. to transparently
swapout/swapin). While we did this defensive clflushing for ordinary
shmem pages, it was forgotten for userptr. Fortunately, userptr objects
are normally cache coherent and so oblivious to the forgotten domain
tracking.

3bd02fa4be drm/i915: Handle YUV subpixel support better
Y41x formats is a 4:4:4 format, so it can be addressed with pixel level accuracy.
Meanwhile it seems that while rotating YUYV 4:2:2 formats need a multiple of 2
for width and height, otherwise corruption occurs.

For YUV 4:2:2, the spec says that w/h should always be even, but we get
away with odd height while unrotated. When rotating it seems corruption
occurs with an odd x/y, and w/h should always be even.
Just to be completely paranoid, reject odd x/y w/h when rotating 90/270.

This is to disable semaphore usage when on vGPU for now. Unfortunately
GVT-g hasn't fully enabled semaphore usage yet, so current guest with
semaphore use would cause vGPU failure.

Although current semaphore failure with vGPU can be simply resolved by
allowing cmd parser to accept MI_SEMAPHORE_WAIT command with address
audit, we're checking general usage of semaphore and how we should
handle it properly for virtualization in consider of function and
security concern. So we decide to request to disable it for now in
guest driver. Once GVT could support it, we would add new compat bit
to turn it on.

5aa2c9ae93 drm/i915: Update TRANS_MSA_MISC for fastsets
Update the DP MSA MISC bits for fastsets. This is needed
when we change between limited and full range RGB output.

On HSW+ changing limited_range does not currently result in a
full modeset since we have don't have the readout code for it
(for DP we could, and probably should, readout from TRANS_MSA_MISC
itself, for HDMI we would have to rely on the infoframe). So
the PIPE_CONF_CHECK() is only performed for pre-HSW platforms.
That means any change in the value will result in a fastset
instead. Fortunately there is no prohibition to changing
TRANS_MSA_MISC dynamically, so it looks like we can legally do
fastsets for this.

f147721986 drm/i915: Remove the 8bpc shackles from DP MST
Allow DP MST to output any color depth. This means deep color as
well as falling back to 6bpc if we would otherwise require too
much bandwidth.

TODO: We should probably extend bw_contstrained scheme to force
all streams on the link to 6bpc if we can't fit the new stream(s)
otherwise.

- Improves our engine-centric view of the world in the engine code

- Allows us to wrap accesses to engine register in nice macros that

b024ab9b2d drm/i915/bios: iterate over child devices to initialize ddi_port_info
Iterate over child devices instead of ports in parse_ddi_ports() to
initialize ddi_port_info. We'll eventually need to decide some stuff
based on the child device order, which may be different from the port
order.

As a bonus, this allows better abstractions for e.g. dvo port mapping.

There's a subtle change in the DDC pin and AUX channel sanitization as
we change the order. Otherwise, this should not change behaviour.

d938da6b13 drm/i915: Disable C3 when enabling vblank interrupts on i945gm
The AGPBUSY thing doesn't work on i945gm anymore. This means
the gmch is incapable of waking the CPU from C3 when an interrupt
is generated. The interrupts just get postponed indefinitely until
something wakes up the CPU. This is rather annoying for vblank
interrupts as we are unable to maintain a steady framerate
unless the machine is sufficiently loaded to stay out of C3.

To combat this let's use pm_qos to prevent C3 whenever vblank
interrupts are enabled. To maintain reasonable amount of powersaving
we will attempt to limit this to C3 only while leaving C1 and C2
enabled.

v2: Use READ_ONCE() (Chris)

8f49673ef9 drm/i915: Pick the first mode from EDID as the fixed mode when there is no preferred mode
Some monitors apparently forget to mark any mode as preferred in the
EDID. In this particular case we have a very generic looking ID
"PNP Model 0 Serial Number 4" / "LVDS 800x600" so a specific quirk
doesn't seem particularly wise. Also the quirk we have
(EDID_QUIRK_FIRST_DETAILED_PREFERRED) is actually defunct so we'd
have to fix it first.

When there is no preferred mode we currently fall back to the VBT.
That approach fails us here as the VBT mode is 1024x768 whereas
the panel resolution is 800x600. So instead of falling back to the
VBT when there is no preferred mode let's just pick the first
probed mode. Only if the EDID provided no modes we fall back to
the VBT.

For this machine the VBIOS would appear to select the 800x600
60Hz EST mode rather than the first detailed mode (which is
the new fallback will pick). The two modes differ only by
having opposite sync polarities, which does not seem to matter
to the panel in question.

v2: Make sure the probed_modes list is not empty

ea593dbba4 drm/i915: Allow contexts to share a single timeline across all engines
Previously, our view has been always to run the engines independently
within a context. (Multiple engines happened before we had contexts and
timelines, so they always operated independently and that behaviour
persisted into contexts.) However, at the user level the context often
represents a single timeline (e.g. GL contexts) and userspace must
ensure that the individual engines are serialised to present that
ordering to the client (or forgot about this detail entirely and hope no
one notices - a fair ploy if the client can only directly control one
engine themselves ;)

In the next patch, we will want to construct a set of engines that
operate as one, that have a single timeline interwoven between them, to
present a single virtual engine to the user. (They submit to the virtual
engine, then we decide which engine to execute on based.)

To that end, we want to be able to create contexts which have a single
timeline (fence context) shared between all engines, rather than multiple
timelines.

v2: Move the specialised timeline ordering to its own function.

b917154172 drm/i915: Extend CONTEXT_CREATE to set parameters upon construction
It can be useful to have a single ioctl to create a context with all
the initial parameters instead of a series of create + setparam + setparam
ioctls. This extension to create context allows any of the parameters
to be passed in as a linked list to be applied to the newly constructed
context.

v2: Make a local copy of user setparam (Tvrtko)
v3: Use flags to detect availability of extension interface

e0695db729 drm/i915: Create/destroy VM (ppGTT) for use with contexts
In preparation to making the ppGTT binding for a context explicit (to
facilitate reusing the same ppGTT between different contexts), allow the
user to create and destroy named ppGTT.

v2: Replace global barrier for swapping over the ppgtt and tlbs with a
local context barrier (Tvrtko)
v3: serialise with struct_mutex; it's lazy but required dammit
v4: Rewrite igt_ctx_shared_exec to be more different (aimed to be more
similarly, turned out different!)

v5: Fix up test unwind for aliasing-ppgtt (snb)
v6: Tighten language for uapi struct drm_i915_gem_vm_control.
v7: Patch the context image for runtime ppgtt switching!

9d1305ef80 drm/i915: Introduce the i915_user_extension_method
An idea for extending uABI inspired by Vulkan's extension chains.
Instead of expanding the data struct for each ioctl every time we need
to add a new feature, define an extension chain instead. As we add
optional interfaces to control the ioctl, we define a new extension
struct that can be linked into the ioctl data only when required by the
user. The key advantage being able to ignore large control structs for
optional interfaces/extensions, while being able to process them in a
consistent manner.

In comparison to other extensible ioctls, the key difference is the
use of a linked chain of extension structs vs an array of tagged
pointers. For example,

struct drm_amdgpu_cs_chunk {
        __u32           chunk_id;
        __u32           length_dw;
        __u64           chunk_data;
};

struct drm_amdgpu_cs_in {
        __u32           ctx_id;
        __u32           bo_list_handle;
        __u32           num_chunks;
        __u32           _pad;
        __u64           chunks;
};

allows userspace to pass in array of pointers to extension structs, but
must therefore keep constructing that array along side the command stream.
In dynamic situations like that, a linked list is preferred and does not
similar from extra cache line misses as the extension structs themselves
must still be loaded separate to the chunks array.

v2: Apply the tail call optimisation directly to nip the worry of stack
overflow in the bud.
v3: Defend against recursion.
v4: Fixup local types to match new uabi

Opens:
- do we include the result as an out-field in each chain?
struct i915_user_extension {
	__u64 next_extension;
	__u64 name;
	__s32 result;
	__u32 mbz; /* reserved for future use */
};
* Undecided, so provision some room for future expansion.

d067994cc4 drm/i915/selftests: Calculate maximum ring size for preemption chain
32 is too many for the likes of kbl, and in order to insert that many
requests into the ring requires us to declare the first few hung --
understandably a slow and unexpected process. Instead, measure the size
of a singe requests and use that to estimate the upper bound on the
chain length we can use for our test, remembering to flush the previous
chain between tests for safety.
