Hi Linus,

I missed a drm-misc-next pull for the main pull last week. It wasn't
that major and isn't the bulk of this at all. This has a bunch of
fixes all over, a lot for amdgpu and i915.

This contains a backmerge of 5.15 as we had a bunch of fixes queued up
in the past couple of days that were based on fixes that were in 5.15,
so I did a backmerge in so I could land them now instead of waiting
for post rc1. I think this also screwed up the diffstat.

Dave.

Ugh.

The i915 conflict was trivial, but made me aware of that absolutely
disgusting "wbinvd_on_all_cpus()" hack.

And that thing is much too ugly to survive. I made my merge resolution
remove that disgusting thing.

That driver is x86-only anyway, so it all seemed completely bogus in
the first place.

And if there is some actual non-x86 work in progress for i915, then
that wbinvd_on_all_cpus() needs to be replaced with something proper
and architecture-neutral anyway, most definitely involving a name
change, and almost certainly also involving a range for the cache
writeback.

Because that "create broken macro on other architectures" thing is
*NOT* acceptable.

And I sincerely hope to the gods that no cache-incoherent i915 mess
ever makes it out of the x86 world. Incoherent IO was always a
historical mistake and should never ever happen again, so we should
not spread that horrific pattern around.

i915 will no longer be x86-64 only in theory, since Intel now produces
PCIe graphics cards using the same hw designs. These shouldn't AFAIK
require the same incoherent architecture, though PCIe unsnooped
transactions are a thing in the real world.

The thing is the same driver needs to build/work for the integrated
and discrete cards, hence this hack, but I'm sure someone can Intel
can do better.

I'll leave it to Daniel to figure out who/how.

Dave.

Well, at least in my tree, it still has the "depends on X86", along
with several other x86-only things (like "select INTEL_GTT", which is
also x86-only)

So by the time that non-x86 theory becomes reality, hopefully the i915
people will also have figured out how to do the cache flushing
properly.

And hopefully that "do it properly" ends up being simply that the
particular configuration that ends up being portable simply doesn't
need to do it at all and can statically just not build it,
sidestepping the issue entirely.

Fingers crossed.

.. of course, I'm also sure some clueless hardware engineer is still
convinced that non-coherent IO is the way to go for graphics, and that
doing cross-CPU IPIs to write back all caches is somehow still a valid
model. Because some people were still convinced about that not _that_
long ago. Hopefully reality (perhaps in the form of Apple) has caused
people to finally reconsider.

For non-x86 / discrete graphics, plan is only coherent mappings, 
although the "Just not build it" part hasn't been properly figured out 
yet I guess. But point taken.

Thanks,

Yeah it's work in progress and 12+ years of x86 pile up high&deep aren't
easy to fix. So please assume the depends on X86 is gone already (and
select INTEL_GTT is optional, it's only needed for igfx older than about 8
years or so), but we can't do that yet because all the build boots would
run out of air screaming so much :-)

Yeah for non-x86 it'll be standard dma-api all the way down. For x86 that
ship sailed long ago, but also I'm not clear on why we added a new cache
flush primitive for that instead of just continuing to use clflush like
we've done since forever. For x86 integrated gpu we _know_ which cpu is
there, clflush will exist. So any new horrors shouldn't be needed, not
sure why a wbinvd_on_all_cpus slipped in.
