[PATCH 00/10] drm/i915/display: identify display steppings in display code

[Jani Nikula]

Use a Single Point of Truth for display stepping detection instead of
duplicating in i915 and xe.

Jani.

[PATCH 01/10] drm/xe/display: fix compat IS_DISPLAY_STEP() range end

[Jani Nikula]

It's supposed to be an open range at the end like in i915. Fingers
crossed that nobody relies on this definition.

I guess this can be removed already.

I think the various IS_DISPLAY_IP_STEP uses in the driver were already
assuming the corrected logic from this patch, so we've just been
applying workarounds to some steppings where they weren't technically
required.  The risk now would be if a workaround was somehow recorded
with incorrect bounds in the workaround database itself and we were
masking that misdocumentation with the wrong logic.  That doesn't seem
terribly likely though.

A simple grep is a bit misleading because IS_DISPLAY_STEP gets used by
IS_DISPLAY_IP_STEP, which is what we use instead on the newer
GMD_ID-based platforms.  If you grep instead for IS_DISPLAY_IP_STEP, it
turns up some MTL, BMG, and LNL workarounds that would have been
impacted.  But as noted above, I still don't think there's much risk
here since it would only be a problem if the workaround documentation
itself was incorrect.

[PATCH 02/10] drm/xe/display: remove intel_display_step_name() to simplify

[Jani Nikula]

The intel_display_step_name() is an unnecessary extra
indirection. Simplify by just adding a macro to map intel_step_name() to
xe_step_name().

We'll need to temporarily add a compat INTEL_DISPLAY_STEP() for this.

[PATCH 04/10] drm/xe/step: define more steppings E-J

[Jani Nikula]

These are primarily needed for compat reasons with display code in
upcoming changes. There's no harm in having them.

While at it, add a comment about the requirement to match against GMD ID
value spacing.

[PATCH 05/10] drm/i915/display: rename IS_DISPLAY_IP_RANGE() to IS_DISPLAY_VER_FULL()

Unify macro naming. Be more in line with DISPLAY_VER() and
IS_DISPLAY_VER().

be fine.

[PATCH 07/10] drm/i915/display: identify display steppings in display probe

[Jani Nikula]

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.

Can't subdesc still be NULL here?  And if we change this to something
like "subdesc ? &subdesc->step_info : NULL" then we'll also need a
nullcheck inside get_pre_gmdid_step as well to prevent a npd.

Indeed, good catch! And CI appears to have caught it too.

[PATCH v2] drm/i915/display: identify display steppings in display probe

[Jani Nikula]

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.

v2: Handle NULL subdesc (Matt)

Re: [PATCH v2] drm/i915/display: identify display steppings in display probe

[Gustavo Sousa]

Quoting Jani Nikula (2024-08-21 06:50:36-03:00)
>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.

I believe we can be sure that step != STEP_NONE at this point. Are we
keeping this only to guard against bugs from future changes?

[PATCH 08/10] drm/i915/display: switch to display detected steppings

[Jani Nikula]

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.

Thanks for the reviews and acks, pushed to din.

I did some (but not exhaustive) cross-checking between drm-tip and
patchwork CI results, and didn't spot any differences in dmesg on the
steppings.

I also posted a slightly modified series to trybot, with a patch [1] to
warn on any differences between steppings before and after the changes,
all good AFAICT.

BR,
Jani.
