Do not create the display debugfs files when we don't have display.

Based on previous patch by José Souza.

First check in the function is if swsci() is supported. All the error
paths are easy to figure out the reason, so remove the extra debug
message: it's normal not to support swsci() e.g. in dgfx.

v2: Rather than special case dgfx, just remove the debug message
    (from Ville)

GT_PERF_STATUS and RP_STATE_LIMITS were added a long time ago in
commit 3b8d8d91d51c ("drm/i915: dynamic render p-state support for Sandy
Bridge").  Other than printing their values in debugfs we don't do
anything with them.  There's not much useful information in them. These
registers may change location in future platforms, but instead of adding
new locations, it's simpler to just remove them.

This code seems to have been updated for Gen9LP, so that would indicate
the debugging information is useful, right? The value is even decoded, not
simply dumped as most registers. So I would be hesitant to drop it for
not being useful.

The second question is why we have a huge block of 1-to-1 duplicated
code in there. Has there been an incorrect merge or some transition has
been left mid-way?

but just updating the register in itself for a new gen doesn't mean it's
actually useful... the commit message where this happened is pretty
vague: 350405623ff3 ("drm/i915: Update rps frequencies for BXT")

My first reaction would be to do the same if the register had moved or
if it ceased to exist in a new platform. Talking with Matt Roper some
time ago we arrived to the conclusion that just printing these values is
not giving us much benefit and it could very well be accomplished by
intel_reg.

So answering the question:  is it really useful as is? IMO, no.

not a bad merge, no. It seems to be to preserve the previous file
location since now it moved to be inside a gt dir. Long term I think
this is bad both because of the code duplication and because it's easy
to update one and forget the other.

A quick discussion on #intel-gfx seems to indicate it was used for
bug triaging in the past year. So that would indicate it is still
useful to include.

So let's not remove it.

I started a discussion in the thread of the original patch which called
to move code but left the old code in place too, effectively copying it.

When this path was written and such code duplication noticed, would have
been good to highlight or address the code duplication.

getting back to this as we are trying to upstream XeHP-SDV that doesn't
have access to the MCHBAR. So do you think we should just make it
conditional instead of removing?

I'm still on the side that this additional code doesn't bring much value
and could be replaced by intel-reg.

yes, but it doesn't mean there will be an action regarding that, as can
be noticed since that duplication is still there today and this patch
applies cleanly :-/... and they had slightly different changes according
to

Just took a look for a potential deduplication fix there:

the deduplication has now being merged together with fixing of the file
names: https://patchwork.freedesktop.org/series/94827/

Back to the previous question...  Does the silence here mean
there is no interest to block this anymore?

As noted by me and Matt Roper there is very little value in keeping
this. Even if it was used once in a year for bug triaging, it could very
well had used intel_reg - this is just adding to the maintenance
burden for new platforms. Who used it so I can talk to the person to
understand the gap?  Adding some more people in Cc who could possibly
know.

thanks

Yes, please let's make this conditional.

In general I'd agree. However:

1. Sometimes it is very hard to find out what registers and bits have
some useful information.
2. If it is hard to remove sometimes it is harder to add some information
like this.
3. I was not part of the IRC chat that Joonas mentioned, but apparently
this data was useful in the past for some cases.

Thanks,
Rodrigo.

I will disagree and commit since 2 maintainers are against the
removal. I will send a new updated patch. Just to make my point clear:

1) This doesn't expose anything more than what is available with
intel_reg

2) we are already printing the wrong value for "recent" platforms:
one of the register wasn't updated for anything after gen9. The other
register doesn't actually seem to exist anymore after gen9.

3) It adds to the maintenance, particularly because this is an mchbar
register which is not available in bspec

4) It's still not clear how exactly this was useful
