[RFC PATCH] drm/xe/bo: Honor madvise(2) advices

[RFC PATCH] drm/xe/bo: Honor madvise(2) advices

[Thomas Hellström]

The user can give advices as to how the CPU will access an
address range. Use those advices to determine the number of
bo pages to prefault on a page-fault.

Do this regardless of whether we can find a way to avoid the
fairly slow vm_insert_pfn_prot() to populate buffer
object maps.

Initially, fault up to 512 pages on sequential access and
a single page on random access.

Ah, interesting. Do we know if any UMD is making use of these special 
flags today? Just wondering if this might be a visible change or not? 
Also would it make sense to document/advertise this somewhere for UMD 
folks, in case this has an immediate benefit for them?

I guess would be good to add an IGT which uses both flags, if we don't 
already?

Anyway, I think change makes sense,

I also have a question here - does Xe / TTM support faulting in THP on
the CPU side? Is that something we should also look at doing based on
madvise / global THP settings? Would that help mitigate the slow
vm_insert_pfn_prot too?

I'm not aware of any.

No we don't. Just trying to get some feedback at this point. Reason is
we've got some complaints about xe being significantly slower on first
CPU access than i915. There is resistance adding something i915-like
from core mm, and until we find out a way to do that cleanly, this
might perhaps suffice. Trying to get that confirmed / rejected.

It would probably help a lot, as long as we actually get 2MiB pages
from TTM. 

I had that implemented in TTM once with vmwgfx the only user, and it
was working fine except one very important detail: I had implemented it
based on vma information rather than PTE-based information, so
get_user_pages_fast() didn't recognize these pages and was terribly
confused. So it had to be ripped out.

If we're going to try that again, we need to talk to x86 arch to get a
PMD_PUD_SPECIAL pmd/pud flag that behaves just like PTE_SPECIAL, so
that things like get_user_pages_fast() ignore these huge PTEs. Auditing
all page-walks in core-mm for this is non-trivial.

But if that is done, we could bring in that stuff again, although
Christian wasn't very fond of having it in TTM.

But I think it would also be very beneficial for things like ioremap()
and friends.

Hmm, yes this seems like a pretty big win too considering Mesa now
always allocates 2M BOs and then suballocates smaller allocations in
user space. So we should pretty much always should be getting 2M pages /
faults.

Agree, core-mm page walks are non-trivial to audit. Recently looked at
2M device pages series and it really wasn't all that bad though.

Out of technical depth on the PTE_SPECIAL comment, but can dig in a bit
here. We do have a maintainer of x86 at Intel (Dave Hansen) which we can
float any ideas wrt to this topic though.

We can perhaps bring this up as an option to Christian - from my limited
knowledge on this topic, this seems like something worth while to do
regardless of the PAT issue as just seems like a pretty big win. This
however is very unlikely to make it into customer kernels which are
complaining about this perf issue, so I think ww need to explore other
options too.

Yeah, I was talking to those people back then and they suggested using
a flag at least initially separate from PTE_SPECIAL. (There are some
available flags in the huge PMDs). But at the time x86_32 was a thing
and using one of the suggested flags would make updating the 64-bit
PTEs with x86_32 the way it was implemented become racy, on top of all
other complications. So while I made significant progress back then, I
decided there were more important things to do, and stopped.

Maybe for the issue at hand (I completely understand the NAK of using
apply_to_page_range() from within drivers) maybe we could get a go-
ahead for exporting some useful interfaces from core mm: Like perhaps
vmf_insert_pfns_prot() that takes an array of pfns and inserts them,
and perhaps vmf_insert_pages_as_pfns_prot() which would do the same for
struct page pointer arrays These could do the slow PAT adjustments once
and then insert all pages/pfns using a single page-walk. Either using
apply_to_page_range() or the more generic pagewalk. Could perhaps look
at the i915 implementation, particularly for the iomap stuff and see if
there's something reusable.
