[Intel-gfx] [PATCH 0/4] Invalidate TLB cache for all GT's

[Andi Shyti]

Hi,

This series revisits a once-trendy topic: TLB invalidation
support for multi-gt.  It's a theme that's been passed around and
reshaped by several of us.

I've filtered out most of the original changes from this series,
initially sent by Mauro [1]. His ideas were inspired by some
changes from Chris, who in turn was inspired by a change from
me[2], all of which stemmed from offline talks by Chris (it's
like a game of inspiration tag!).

What I've done is simply rebase and refactor the patches,
focusing solely on the changes needed for multi-gt TLB
invalidation in MMIO memory. The result is a leaner, more
targeted proposal.

Other patches from the original series might follow.

Thanks,
Andi
