Several workarounds are guarded by IS_MTL_GRAPHICS_STEP.  However none
of these workarounds are actually tied to MTL as a platform; they only
relate to the Xe_LPG graphics IP, regardless of what platform it appears
in.  At the moment MTL is the only platform that uses Xe_LPG with IP
versions 12.70 and 12.71, but we can't count on this being true in the
future.  Switch these to use a new IS_GFX_IPVER_STEP() macro instead
that is purely based on IP version.  IS_GFX_IPVER_STEP() is also
GT-based rather than device-based, which will help prevent mistakes
where we accidentally try to apply Xe_LPG graphics workarounds to the
Xe_LPM+ media GT.

Do we really need/want a combined/long macro like this and not split it out
to something like a more readable IS_GFX_IPVER && IS_<...>_STEP?


On this part, wouldn't that make it less readable?  Right now these
conditions are an ||'d list of cases for which the workaround should
apply (relating to various entries in the workaround database).  If we
split the version, stepping, and GT checks out into separate macros
we'll get more complex conditions that are a mix of && and ||.  We can
try that, but my gut feeling is that it's going to be more error-prone
since we'll have to be really careful to always get the parenentheses in
the right places.  Also many people (myself included) are already having
some trouble adjusting to the new idea of GT (primary vs media) being an
important factor that needs to be considered in the workaround
condition; one of the goals with these new macros was to make sure that
got included in the macro so that it couldn't be omitted by accident.
Oh well I don't know.. maybe. It's just that I find that as amount of all uppercase blocks grows over a certain limit things become quite an eyesore and hard to read. One line of: 

if (IS_GFX_IPVER_STEP(i915, IP_VER(12,70), STEP_A0, STEP_B0))
Is already borderline. A few of those on the same line is just hard to parse. But your argument also has merit so again, don't know. 

What I was suggesting is to maybe have:

IS_GFX_IPVER_STEP(i915, IP_VER(12,70), IP_STEP(A0, B0))

Marginally shorter.

Maybe find a shorted name for IS_GFX_IPVER_STEP?

IS_GFX_IP(i915, IP_VER(12,70), IP_STEP(A0, B0))

?
Too bad we can't have that macro take the stepping argument as optional. Or maybe it is possible, I don't know C macro magic that well.
Also, if we added GT based macros we could get away with encoding the GT type in the macro name. Asking the GT/tile directrly about their IP_VER. Not sure how widely applicable tha would be so just a thought. 

IS_IP(gt, IP_VER(12, 70))

GT_VER_FULL(gt) == IP_VER(13, 0)

Unless that falls apart with that GT is not a tile story.

Adding Jani since we were discussing this direction over the past few weeks.

Hm.. macro trickery for stepping ranges to make it more compact? Like making
the STEP_ prefix be prepended by the macro. Don't know..


One other thing that we could consider if some of these things are
getting too long is eliminating IP_VER() and using the "versionx100"
scheme that Xe and Mesa use.  On one hand that makes me a bit nervous
since GMD_ID's release number is 8 bits and could go past 100 on future
platforms, which would break the scheme (and we're already up to .71 on
MTL).  But on the other hand it does make the code simpler and shorter
and we can always wait and see if we ever actually get a platform with
version X.100 or something before we really worry about what to do
there.

The other point in favor of switching to versionx100 is that we wouldn't
have an inconsistent mix of both IP_VER() and verx100 in the Xe driver
where the display code comes from i915 but the non-display code is
separate.
