It's confusing to have a *set* function that actually probes the
hardware rather than receiving a parameter. Rename it to *probe* along
with prefix removal and comment in the relevant places that the
has_flat_ccs flag may be overridden in runtime.
While at it, fix the mixed declaration of struct xe_gt.

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.)

The different approach used by xe regarding the initialization of
display HW has been proved a great addition for early driver bring up:
core xe can be tested without having all the bits sorted out on the
display side.
On the other hand, the approach exposed by i915-display is to *actively*
disable the display by programming it if needed, i.e. if it was left
enabled by firmware. It also has its use to make sure the HW is actually
disabled and not wasting power.
However having both the way it is in xe doesn't expose a good interface
wrt module params. From modinfo:
disable_display:Disable display (default: false) (bool)
enable_display:Enable display (bool)
Rename enable_display to probe_display to try to convey the message that
the HW is being touched and improve the module param description. To
avoid confusion, the enable_display is renamed everywhere, not only in
the module param. New description for the parameters:
disable_display:Disable display (default: false) (bool)
probe_display:Probe display HW, otherwise it's left untouched (default: true) (bool)

VFs do not have direct access to the GMDID register and must obtain
its value from the GuC. Since we need GMDID value very early in the
driver probe flow, before we even start the full setup of GT and GuC
data structures, we must do some early initializations ourselves.
Additionally, since we also need GMDID for the media GT, which isn't
created yet, temporarly tweak the root GT type into MEDIA to allow
communication with the correct GuC, as only it can provide the value
of the media GMDID register.

Rather than trying to identify exactly which engines are available on
each platform in the IP descriptor, just include the list of all media
engines that the IP could theoretically support (i.e., 8 VCS + 4 VECS).
We still rely on the media fuse registers to tell us which specific
engine instances are actually present on a given platform, so there
shouldn't be any functional change. This will help prevent mistakes
with engine numbering (for example ambiguity about whether the 2nd VCS
engine on a platform with exactly two engines is numbered "VCS1" or
"VCS2") and will also future-proof the code a bit more in case new SKUs
or platform refreshes extend the engine list in the future.
Note that the media fuse register technically has an 8-bit field for
VECS engine presence starting on Xe2. However there's still no MMIO
register range reserved for VE engines above VECS3, so VE0-VE3 is still
consider the "maximum" VE engine mask that the driver can support for
now.

On platforms with multiple BCS engines (i.e., PVC and Xe2), not all BCS
engines are created equal. The BCS0 engine is what the specs refer to
as a "resource copy engine," which supports the platform's full set of
copy/fill instructions. In contast, the non-BCS0 "service copy" engines
are more streamlined and only support a subset of the GPU instructions
supported by the resource copy engine. Platforms with both types of
copy engines always support the MEM_COPY and MEM_SET instructions which
can be used for simple copy and fill operations on either type of BCS
engine. Since the simple MEM_SET instruction meets the needs of Xe's
migrate code (and since the more elaborate XY_FAST_COLOR_BLT instruction
isn't available to use on service copy engines), we always prefer to use
MEM_SET for clearing buffers on our newer platforms.
We've been using a 'has_link_copy_engine' feature flag to keep track of
which platforms should use MEM_SET for fills. However a feature flag
like this is unnecessary since we can already derive the presence of
service copy engines (and in turn the MEM_SET instruction) just by
looking at the platform's pre-fusing engine list. Utilizing the engine
list for this also avoids mistakes like we've made on Xe2 where we
forget to set the feature flag in the IP definition.
For clarity, "service copy" is a general term that covers any blitter
engines that support a limited subset of the overall blitter instruction
set (in practice this is any non-BCS0 blitter engine). The "link copy
engines" introduced on PVC and the "paging copy engine" present in Xe2
are both instances of service copy engines.

- Rewrite / expand the commit message. (Bala)

Starting with Xe2, a 5-level page table is always used, regardless of
the actual virtual address range supported by the platform. The two
values need to be tracked separately in the device descriptor since Xe2
platforms only have a 48 bit virtual address range.

Define a common set of Xe2 graphics feature flags and definitions that
will be used for all platforms in this family.
Several of the feature flags are inherited unchanged from Xe_HP and/or
Xe_HPC platforms:
- dma_mask_size remains 46 (Bspec 70817)
- supports_usm=1 (Bspec 59651)
- has_flatccs=1 (Bspec 58797)
- has_asid=1 (Bspec 59654, 59265, 60288)
- has_range_tlb_invalidate=1 (Bspec 71126)
However some of them still need proper implementation in the driver to
be used, so they are disabled.
Notable Xe2-specific changes:
- All Xe2 platforms use a five-level page table, regardless of the
virtual address space for the platform. (Bspec 59505)
The graphics engine mask represents the Xe2 architecture engines (Bspec
60149), but individual platforms may have a reduced set of usable
engines, as reflected by their fusing.

The choice of Y-major tiling format (either the legacy "TileY" or the
newer "Tile4") is based on graphics IP version (12.50 and beyond have
Tile4, earlier platforms have TileY). The tracking in xe was originally
added to allow re-using display from i915. However as of i915 commit
4ebf43d048 ("drm/i915: Eliminate has_4tile feature flag"), the display
code determines TileY vs Tile4 itself, so this can be removed from xe.

gt_count is only being incremented when initializing the primary GT;
since the media GT sets the ID directly, gt_count is not incremented

Allow xe_device_get_gt() and for_each_gt() to operate as expected on
platforms with standalone media.
FIXME: We need to figure out a consistent ID scheme for GTs. This patch
keeps the pre-existing behavior of 0/1 being the GT IDs for both PVC
(multi-tile) and MTL (multi-GT), but depending on the direction we
decide to go with uapi, we may change this in the future (e.g., to
return 0/1 on PVC and 0/2 on MTL). Or if we decide we only need to
expose tiles to userspace and not GTs, we may not even need ID numbers
for the GTs anymore.
v2:
- Restructure a bit to make the assertions more clear.
- Clarify in commit message that the goal here is to preserve existing
behavior; UAPI-visible changes may be introduced in the future once
we settle on what we really want.
v3:
- Store total GT count in xe_device for ease of lookup. (Brian)
- s/(id__++)/(id__)++/ (Gustavo)
