It used to be handy that we only had a couple of headers, but over time
intel_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.
Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
only where needed, and sort the modified include directives while at it
and as needed.
No functional changes.

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)

edram is not part of uncore and there is no requirement for the
detection to be done before we initialize the uncore functions. The
first check on HAS_EDRAM is in the ggtt_init path, so move it to
i915_driver_init_hw, where other dram-related detection happens.
While at it, save the size in MB instead of the capabilities because the
size is the only thing we look at outside of the init function.

The intent was to expose these as part of the means to perform full
context recovery (though not the SINGLE_TIMELINE, that is for later and
just sucked as collateral damage). As that requires a couple more
patches to complete the series, roll back the earlier chunks of ABI for
an intervening PR. We keep all the internals intact and under selftests.

It can be useful to have a single ioctl to create a context with all

ioctls. This extension to create context allows any of the parameters

context.

When the system idles, we switch to the kernel context as a defensive
measure (no users are harmed if the kernel context is lost). Currently,
we issue a switch to kernel context and then come back later to see if
the kernel context is still current and the system is idle. However,
if we are no longer privy to the runqueue ordering, then we have to
relax our assumptions about the logical state of the GPU and the only
way to ensure that the kernel context is currently loaded is by issuing
a request to run after all others, and wait for it to complete all while
preventing anyone else from issuing their own requests.
v2: Pull wedging into switch_to_kernel_context_sync() but only after
waiting (though only for the same short delay) for the active context to
finish.

In the next patch, we are introducing a broad virtual engine to encompass
multiple physical engines, losing the 1:1 nature of BIT(engine->id). To
reflect the broader set of engines implied by the virtual instance, lets
store the full bitmask.
v2: Use intel_engine_mask_t (s/ring_mask/engine_mask/)
v3: Tvrtko voted for moah churn so teach everyone to not mention ring
and use $class$instance throughout.
v4: Comment upon the disparity in bspec for using VCS1,VCS2 in gen8 and
VCS[0-4] in later gen. We opt to keep the code consistent and use
0-index naming throughout.

No functional change. Just a reorg to match the preferred
behavior.
When rebasing internal branch on top of latest sort I noticed
few more cases that needs to get reordered.
Let's do in a bundle this time and hoping there's no other
missing places.
v2: Check for HSW/BDW ULT before generic IS_HASWELL or
IS_BROADWELL or it doesn't work as pointed by Ville.
But also ULT came afterwards anyway.
v3: Accepting suggestions from Lucas:
Sort CNL/CFL, KBL/SKL, and use <= 8 removing chv and bdw.

Having introduced per-context seqno, we now have a means to identity
progress across the system without feel of rollback as befell the
global_seqno. That is we can program a MI_SEMAPHORE_WAIT operation in
advance of submission safe in the knowledge that our target seqno and
address is stable.
However, since we are telling the GPU to busy-spin on the target address
until it matches the signaling seqno, we only want to do so when we are
sure that busy-spin will be completed quickly. To achieve this we only
submit the request to HW once the signaler is itself executing (modulo
preemption causing us to wait longer), and we only do so for default and
above priority requests (so that idle priority tasks never themselves
hog the GPU waiting for others).
As might be reasonably expected, HW semaphores excel in inter-engine
synchronisation microbenchmarks (where the 3x reduced latency / increased
throughput more than offset the power cost of spinning on a second ring)
and have significant improvement (can be up to ~10%, most see no change)
for single clients that utilize multiple engines (typically media players
and transcoders), without regressing multiple clients that can saturate
the system or changing the power envelope dramatically.
v3: Drop the older NEQ branch, now we pin the signaler's HWSP anyway.
v4: Tell the world and include it as part of scheduler caps.

The use of drmP.h is discouraged and removal of it from
drm_modeset_helper.h caused i915 to fail to build.
This patch introduce the necessary fixes to prepare for the
drmP.h removal from drm_modeset_helper.h.
In the files touched the lists of include files was grouped
and sorted.
Build tested on x86 and arm allmodconfig / allyesconfig.

We generally omit register polling from the i915_reg_rw tracepoint.
Understandable since polling could generate a lot of noise in the
trace. The downside is that the trace is incomplete. As a compromise
let's trace the final register value observed while polling. That
should be generally sufficient to observe what the code should be
doing next.
I suppose in some cases it might make sense to also trace the initial
register value, and maybe the number of times we polled. But that
would require a separate tracepoint so let's leave it for the future.
The other users of _NOTRACE() are i915_pmu and i2c bitbanging,
which I decided to leave alone.
Next we should do something to claw back the tracepoints for
planes and whatnot which were switched to _FW() a while back.
I guess just new macros for raw_rw+trace. The question is
what to call it?

This is only used by drm_irq_install(), which is an optional helper.
For legacy pci devices this is required (due to interrupt sharing without
msi/msi-x), and just making this the default exactly matches the behaviour
of all existing drivers using the drm_irq_install() helpers. In case that
ever becomes wrong drivers can roll their own irq handling, as many
drivers already do (for other reasons like needing a threaded interrupt
handler, or having an entire pile of different interrupt sources).
v2: Rebase
v3: Improve commit message (Emil)

If a non-legacy driver calls these it's valid to assume there is
interrupt support. The flag is really only needed for legacy drivers,
which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL
legacy IOCTL.
Also remove all the flag usage from non-legacy drivers.
v2: Review from Emil:
- improve commit message
- I forgot hibmc, fix that

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.
