[PATCH 1/4] drm/i915: fix guest virtual PCH detection on non-PCH systems

[Jani Nikula]

Virtualized non-PCH systems such as Broxton or Geminilake should use
PCH_NONE to indicate no PCH rather than PCH_NOP. The latter is a
specific case to indicate a PCH system without south display.

Then let's go ahead and document it?

Subject: [PATCH] drm/i915: document PCH_NOP

There's a difference between PCH_NONE and PCH_NOP: the former means we
don't have a PCH while in the latter we do, but it doesn't have the
south display.

Please avoid sending suggestion patches in-reply-to existing
series. This confused patchwork and screwed up CI for the series, which
was already a resend just to get CI. :(

I'm resending the series, with your documentation patch added, but I'm
keeping the extra explanatory text in the last patch. I think it's
warranted.

BR,
Jani.

ugh, sorry.  Sometimes just adding a oneline diff is much better than
a hundred words explaining :( ... IMO pw is trying to be smarter than
it should here or not being smart enough. Nonetheless I won't do that
anymore.

I feel you, a patch is more precise.

I think there were earlier complaints about what it did recognize and
what it didn't. I'd be open to only accepting new versions of patches
from whoever sent the original patch. Or requiring patch subjects don't
start with "Re:". Or both.

I was annoyed, but I'm perhaps more annoyed that you can't do this
without confusing patchwork. In the end, I wouldn't want to hamper
review by blocking something that comes naturally to people.

No matter what you do here it will misbehave in some scenarios and
break someone's workflow :<

Originally we required the patches to have X-Mailer set to
git-send-email, which seems reasonable, but that annoyed people because
their servers were stripping out those headers.

Other people send out the patches by feeding them to the drafts folder
through IMAP and then sending them out. This, depending on the
provider's configuration, also gobbles up a thing or two.

Because of the above I am not sure about trusting "Re:" and matching
"From:" headers as good enough indicators either.

It just adds more opaque "smartness". I already can foresee questions
asking "why my v2 was not picked up?" and someone would have to debug it
down the line.

Was the address different (+XYZ before @)? Has that someone used
--subject-prefix=re:? Is it an actual bug? Etc.

Just add the following header:
"X-Patchwork-Hint: comment"
to emails that you type out manually.

For mutt it's as easy as adding:
"my_hdr X-Patchwork-Hint: comment"
to your .muttrc

This may not work for the same reasons you pointed out that wouldn't
work if people are sending patches.  Is there a format I can use that
will not trigger patchwork from parsing a _reply_? Does removing the
"--------" help? Under the hood does it use git am --scissors or
similar?

Humn... it has its own parser. So if I read
https://github.com/dlespiau/patchwork/blob/master/patchwork/parser.py#L36
correctly, it should be just a matter of omitting the "diff | ---"
lines (or prepending with a "#").

It does make things more difficult if the other person would use "git
am --scissors" though.

Yeah, it's far for perfection and needs additional effort to set the
header up. For me it works, but I always send patches via git-send-email
and always send replies via mutt - I am the simple case.

Yes, that is my understanding as well - if you would ommit the "diff
header" it should not recognize your mail as a patch. But that's yet
another behavior you have to know upfront.

It's really hard to strike a balance here.

One idea is to optimize for the default case (i.e. behavior of
git-send-email), sans the known quirks we have seen so far,
and write this down.

Then, if some patches are getting ignored, this would make a handy
checklist that can be use for troubleshooting and we can also link to
it, kindly asking to adhere to a more standard way of sending patches.

[PATCH 2/4] drm/i915: clean up virtual PCH special case handling

[Jani Nikula]

Use intel_pch_type() also for mapping the no PCH case (PCH id 0) to
PCH_NONE to simplify code.

Also make sure that intel_pch_type() knows all the PCH ids returned by
intel_virt_detect_pch(). Loudly fail if this isn't the case; this
shouldn't happen anyway.

[PATCH 3/4] drm/i915: be more strict about HAS_PCH_NOP() usage

HAS_PCH_NOP() implies a PCH platform without south display, not generic
disabled display. Prefer num_pipes == 0 for PCH independent checks.

[PATCH 4/4] drm/i915: fix PCH_NOP setting for non-PCH platforms

[Jani Nikula]

Setting PCH type to PCH_NOP before checking whether we actually have a
PCH ends up returning true for HAS_PCH_SPLIT() on all non-PCH split
platforms. Fix this by using PCH_NOP only for platforms that actually
have a PCH.
