399f7b6716 drm/i915/uncore: add to_intel_uncore() and use it 
Add to_intel_uncore() function to avoid the inclusion of i915_drv.h from
intel_de.h. This reveals a number of implicit dependencies on i915_drv.h
that need to be added.

For now, to_intel_uncore() can be an inline function, with all the
includes in compat intel_uncore.h, as long as i915_drv.h isn't
included. The implicit dependencies on i915_drv.h is a problem in
display code, but the same is not true for xe_device.h etc.

17d7072607 drm/i915: extract intel_uncore_trace.[ch] 
The i915_reg_rw tracing is a small isolated part of i915_trace.h. Its
users are orthogonal to the other i915_trace.h users as well, and its
implementation does not require all the includes of i915_trace.h. Split
i915_reg_rw tracing to separate intel_uncore_trace.[ch].

The main underlying goal is to reduce implicit includes of i915_drv.h
from display code.

359d2cc1f3 drm/xe: Mimic i915 behavior for non-sleeping MMIO wait 
In upcoming display changes, we will modify the DMC wakelock MMIO
waiting code to choose a non-sleeping variant implementation, because
the wakelock is also taking in atomic context.

While xe provides an explicit parameter (namely "atomic") to prevent
xe_mmio_wait32() from sleeping, i915 does not and implements that
behavior when slow_timeout_ms is zero.

So, for now, let's mimic what i915 does to allow for display to use
non-sleeping MMIO wait. In the future, we should come up with a better
and explicit interface for this behavior in i915, at least while display
code is not an independent entity with proper interfaces between xe and
i915.

v2:
  - Make the tone in comment the comment added in
    __intel_wait_for_register() more explanatory than a FIXME-like text.

5eb2e78559 drm/i915/display: use x100 version for full version and release 
Use x100, or ver * 100 + rel, versions for full IP version checks,
similar to what xe driver does:

- Replace IP_VER(14, 1) inline with 1401, etc.

- Convert DISPLAY_VER_FULL() to DISPLAY_VERx100()

- Convert IS_DISPLAY_VER_FULL() to IS_DISPLAY_VERx100()

- Convert IS_DISPLAY_VER_STEP() to IS_DISPLAY_VERx100_STEP()

This makes ver.rel versions easier to use, follows the xe driver
pattern, and drops the dependency on the IP_VER() macro.

v2: Rebase, drop IP_VER() from xe compat headers

v3: Rebase

If the device is runtime suspended the eDP panel power is also off.
Ignore a short HPD on eDP if the device is suspended accordingly,
instead of checking the panel power state via the PPS registers for the
same purpose. The latter involves runtime resuming the device
unnecessarily, in a frequent scenario where the panel generates a
spurious short HPD after disabling the panel power and the device is
runtime suspended.

06f4d32843 drm/i915: remove IS_LP() 
The .is_lp member of struct intel_device_info and its wrapper IS_LP()
are used to identify just four platforms, VLV/CHV/BXT/GLK. It didn't
become as important as it was perhaps originally planned. Just remove
it, and replace with exact platform identification. In a few places this
becomes slightly verbose, but in many places it improves clarity to
immediately see the exact platforms.

Additionally, this lets us remove the xe compat macro.

2edc6a75f2 drm/i915: switch intel_wakeref_t underlying type to struct ref_tracker * 
For intel_wakeref_t, opaque is reasonable, but disguising the underlying
struct ref_tracker * as an unsigned long is not so great. Update the
typedef to remove one level of disguise.

Although the kernel coding style strongly discourages pointer typedefs,
it's a better alternative, and an incremental improvement on the status
quo. It provides much better type safety than an unsigned long could,
and prevents passing magic -1 instead of INTEL_WAKEREF_DEF. Moreover, it
provides a gradual path for replacing intel_wakeref_t with struct
ref_tracker * if desired.

As an extra safety measure, check for error pointers in
intel_ref_tracker_free() before passing them on to ref_tracker_free(),
to catch any mistakes with mock gt special wakeref value.

83e5af5997 drm/i915 & drm/xe: save struct drm_device to drvdata 
In the future, the display code shall not have any idea about struct
xe_device or struct drm_i915_private, but will need to get at the struct
drm_device via drvdata. Store the struct drm_device pointer to drvdata
instead of the driver specific pointer.

Avoid passing NULL to container_of() via to_i915()/to_xe_device(). (It
does return NULL for NULL pointers when the offset happens to be 0, but
otherwise returns garbage pointers for NULL.)

3034cc8107 drm/xe/pcode: Treat pcode as per-tile rather than per-GT 
There's only one instance of the pcode per tile, and for GT-related
accesses both the primary and media GT share the same register
interface.  Since Xe was using per-GT locking, the pcode mutex wasn't
actually protecting everything that it should since concurrent accesses
related to a tile's primary GT and media GT were possible.

34e804220f drm/xe: Make xe_ggtt_node struct independent 
In some rare cases, the drm_mm node cannot be removed synchronously
due to runtime PM conditions. In this situation, the node removal will
be delegated to a workqueue that will be able to wake up the device
before removing the node.

However, in this situation, the lifetime of the xe_ggtt_node cannot
be restricted to the lifetime of the parent object. So, this patch
introduces the infrastructure so the xe_ggtt_node struct can be
allocated in advance and freed when needed.

By having the ggtt backpointer, it also ensure that the init function
is always called before any attempt to insert or reserve the node
in the GGTT.

v2: s/xe_ggtt_node_force_fini/xe_ggtt_node_fini and use it
    internaly (Brost)
v3: - Use GF_NOFS for node allocation (CI)
    - Avoid ggtt argument, now that we have it inside the node (Lucas)
    - Fix some missed fini cases (CI)
v4: - Fix SRIOV critical case where config->ggtt_region was
      lost (Michal)
    - Avoid ggtt argument also on removal (missed case on v3) (Michal)
    - Remove useless checks (Michal)
    - Return 0 instead of negative errno on a u32 addr. (Michal)
    - s/xe_ggtt_assign/xe_ggtt_node_assign for coherence, while we
      are touching it (Michal)
v5: - Fix VFs' ggtt_balloon

6062ea9398 drm/xe: Encapsulate drm_mm_node inside xe_ggtt_node 
The xe_ggtt component uses drm_mm to manage the GGTT.
The drm_mm_node is just a node inside drm_mm, but in Xe we use that
only in the GGTT context. So, this patch encapsulates the drm_mm_node
into a xe_ggtt's new struct.

This is the first step towards limiting all the drm_mm access
through xe_ggtt. The ultimate goal is to have a better control of
the node insertion and removal, so the removal can be delegated
to a delayed workqueue.

v2: Fix includes and typos (Michal and Brost)

dfc88eac97 drm/i915/display: switch to display detected steppings 
Move the stepping related macros over to display. We can proceed to
remove the compat macros from xe.

Note: Looks like we've failed to actually initialize the display
stepping for GMD ID based platforms in the xe driver. It does get set in
display runtime info, but until now the compat macro used
xe->info.step.display which was not set for GMD ID.

4446387572 drm/i915/display: identify display steppings in display probe 
Both i915 and xe have code to identify display steppings. Start
deduplicating this by, uh, adding a third copy in display code. This is
not yet used for anything other than debug logging. We'll switch over
later.

For platforms before GMD ID, attach the mapping from PCI revision to
stepping in the platform and subplatform descriptors. This is a
considerably cleaner approach than having it completely separate.

Also add a separate field for stepping in display runtime info,
preserving the value from GMD ID.
