[RFC PATCH 00/15] KVM: x86/mmu: Eager Page Splitting for the TDP MMU

[RFC PATCH 00/15] KVM: x86/mmu: Eager Page Splitting for the TDP MMU

[David Matlack]

This series is a first pass at implementing Eager Page Splitting for the
TDP MMU. For context on the motivation and design of Eager Page
Splitting, please see the RFC design proposal and discussion [1].

Paolo, I went ahead and added splitting in both the intially-all-set
case (only splitting the region passed to CLEAR_DIRTY_LOG) and the
case where we are not using initially-all-set (splitting the entire
memslot when dirty logging is enabled) to give you an idea of what
both look like.

Note: I will be on vacation all of next week so I will not be able to
respond to reviews until Monday November 29. I thought it would be
useful to seed discussion and reviews with an early version of the code
rather than putting it off another week. But feel free to also ignore
this until I get back :)

This series compiles and passes the most basic splitting test:

$ ./dirty_log_perf_test -s anonymous_hugetlb_2mb -v 2 -i 4

But please operate under the assumption that this code is probably
buggy.

[RFC PATCH 01/15] KVM: x86/mmu: Rename rmap_write_protect to kvm_vcpu_write_protect_gfn

[David Matlack]

rmap_write_protect is a poor name because we may not even touch the rmap
if the TDP MMU is in use. It is also confusing that rmap_write_protect
is not a simpler wrapper around __rmap_write_protect, since that is the
typical flow for functions with double-underscore names.

Rename it to kvm_vcpu_write_protect_gfn to convey that we are
write-protecting a specific gfn in the context of a vCPU.

No functional change intended.

[RFC PATCH 02/15] KVM: x86/mmu: Rename __rmap_write_protect to rmap_write_protect

[David Matlack]

Now that rmap_write_protect has been renamed, there is no need for the
double underscores in front of __rmap_write_protect.

No functional change intended.

[RFC PATCH 03/15] KVM: x86/mmu: Automatically update iter->old_spte if cmpxchg fails

[David Matlack]

Consolidate a bunch of code that was manually re-reading the spte if the
cmpxchg fails. There is no extra cost of doing this because we already
have the spte value as a result of the cmpxchg (and in fact this
eliminates re-reading the spte), and none of the call sites depend on
iter->old_spte retaining the stale spte value.

Move the kvm_mmu_memory_cache structs into a separate wrapper struct.
This is in preparation for eagerly splitting all large pages during
VM-ioctls (i.e. not in the vCPU fault path) which will require adding

[RFC PATCH 06/15] KVM: x86/mmu: Derive page role from parent

[David Matlack]

Derive the page role from the parent shadow page, since the only thing
that changes is the level. This is in preparation for eagerly splitting
large pages during VM-ioctls which does not have access to the vCPU
MMU context.

No functional change intended.

This reduces the number of arguments by 1, cutting down on line lengths.

[RFC PATCH 12/15] KVM: x86/mmu: Split large pages when dirty logging is enabled

[David Matlack]

When dirty logging is enabled without initially-all-set, attempt to
split all large pages in the memslot down to 4KB pages so that vCPUs
do not have to take expensive write-protection faults to split large
pages.

Large page splitting is best-effort only. This commit only adds the
support for the TDP MMU, and even there splitting may fail due to out
of memory conditions. Failures to split a large page is fine from a
correctness standpoint because we still always follow it up by write-
protecting any remaining large pages.

[RFC PATCH 13/15] KVM: x86/mmu: Split large pages during CLEAR_DIRTY_LOG

[David Matlack]

When using initially-all-set, large pages are not write-protected when
dirty logging is enabled on the memslot. Instead they are
write-protected once userspace invoked CLEAR_DIRTY_LOG for the first
time, and only for the specific sub-region of the memslot that userspace
whishes to clear.

Enhance CLEAR_DIRTY_LOG to also try to split large pages prior to
write-protecting to avoid causing write-protection faults on vCPU
threads. This also allows userspace to smear the cost of large page
splitting across multiple ioctls rather than splitting the entire
memslot when not using initially-all-set.

[RFC PATCH 15/15] KVM: x86/mmu: Update page stats when splitting large pages

[David Matlack]

When splitting large pages we need to update the pages stats to reflect
all of the new pages at the lower level. We do not need to change the
page stats for the large page that was removed as that is already
handled tdp_mmu_set_spte_atomic.

I have a similar patch for the old MMU, but it was also replacing 
shadow_root_level with shadow_root_role.  I'll see if I can adapt it to 
the TDP MMU, since the shadow_root_role is obviously the same for both.

This probably deserves a comment:

This refactoring drops this trace point. Is that intentional?

I'm amazed there's only one instance of a check for present and large.

I think this is an artifact of the days when I thought we could avoid

Trying to do that turned out to be a huge pain though and the memory
savings weren't great.
Happy to see this cleaned up.

Just because this always trips me up reading code, I'd suggest naming
the argument large_spte_level or something.
Avoiding a variable called "level" in this function makes it much more explicit.

In the interest of not crashing the host, I think it would be safe to
WARN and return 0 here.
BUG is fine too if that's preferred.

This += makes me nervous. It at least merits a comment explaining
what's going on.
I'd find a |= more readable to make it more explicit and since sptes
aren't numbers.
You could probably also be really explicit about extracting the PFN
and adding to it, clearing the PFN bits and then putting it back in
and I bet the compiler would optimize out the extra bit fiddling.

This functionality could be shoe-horned into
tdp_mmu_iter_cond_resched, reducing code duplication.
I don't know if the extra parameters / complexity on that function
would be worth it, but I'm slightly inclined in that direction.

Ah, right. I was confused by this for a second, but it's safe because
the caches are protected by the slots lock.

I think it would be safe to just WARN and return here as well.

Relating to my other comment above on make_large_page_split_spte, you
could also iterate through the range of PFNs here and pass that as an
argument to the helper function.

Thank you for parameterizing the target level here. I'm working on a
proof of concept for 2M dirty tracking right now (still in exploratory
phase) and this parameter will help future-proof the splitting
algorithm if we ever decide we don't want to split everything to 4k
for dirty logging.

Are mmu_gfn_array_cache and mmu_pte_list_desc_cache wasted here?  I saw that
"struct kvm_mmu_memory_cache" still takes up quite a few hundreds of bytes,
just want to make sure we won't waste them in vain.

Is it intended to only top-up with one cache object?  IIUC this means we'll try
to proactively yield the cpu for each of the huge page split right after the
object is consumed.

Wondering whether it be more efficient to make it a slightly larger number, so
we don't overload the memory but also make the loop a bit more efficient.

Is it intended to try split every time even if we could have split it already?
As I remember Paolo mentioned that we can skip split if it's not the 1st
CLEAR_LOG on the same range, and IIUC that makes sense.

But indeed I don't see a trivial way to know whether this is the first clear of
this range.  Maybe we can maintain "how many huge pages are there under current
kvm_mmu_page node" somehow?  Then if root sp has the counter==0, then we can
skip it.  Just a wild idea..

Or maybe it's intended to try split unconditionally for some reason?  If so
it'll be great to mention that either in the commit message or in comments.

Thanks,

Will there be more numbers to show in the formal patchset?  It's interesting to
know how "First Pass Dirty Memory Time" will change comparing to the rfc
numbers; I can have a feel of it, but still. :) Also, not only how it speedup
guest dirty apps, but also some general measurement on how it slows down
KVM_SET_USER_MEMORY_REGION (!init-all-set) or CLEAR_LOG (init-all-set) would be
even nicer (for CLEAR, I guess the 1st/2nd+ round will have different overhead).

Besides that, I'm also wondering whether we should still have a knob for it, as
I'm wondering what if the use case is the kind where eager split huge page may
not help at all.  What I'm thinking:

  - Read-mostly guest overload; split huge page will speed up rare writes, but
    at the meantime drag readers down due to huge->small page mappings.

  - Writes-over-very-limited-region workload: say we have 1T guest and the app
    in the guest only writes 10G part of it.  Hmm not sure whether it exists..

  - Postcopy targeted: it means precopy may only run a few iterations just to
    send the static pages, so the migration duration will be relatively short,
    and the write just didn't spread a lot to the whole guest mem.

I don't really think any of the example is strong enough as they're all very
corner cased, but just to show what I meant to raise this question on whether
unconditionally eager split is the best approach.

Hello, Paolo

I'm sorry to ask something unrelated to this patchset, but related
to my pending work.

I will still continue to do something on shadow_root_level.  But I
would like to wait until your shadow_root_role work is queued.
And is it a part of work splitting the struct kvm_mmu?

Thanks

Yes, more or less.  I'm basically splitting the "CPU role" (the basic 
and extended role from the processor registers) used for emulation, from 
the "MMU role" (the basic role used for the root shadow page tables). 
Then shadow_root_level/root_level become respectively mmu_role->level 
and cpu_role->base.level.

Yes definitely. I didn't have a lot of time to test this series, hence
the RFC status. I'll include more thorough testing and performance
evaluation in the cover letter for v1.

I'd be happy to add a knob if there's a userspace that wants to use
it. I think the main challenge though is knowing when it is safe to
disable eager splitting. For a small deployment where you know the VM
workload, it might make sense. But for a public cloud provider the
only feasible way would be to dynamically monitor the guest writing
patterns. But then we're back at square one because that would require
dirty logging. And even then, there's no guaranteed way to predict
future guest write patterns based on past patterns.

The way forward here might be to do a hybrid of 2M and 4K dirty
tracking (and maybe even 1G). For example, first start dirty logging
at 2M granularity, and then log at 4K for any specific regions or
memslots that aren't making progress. We'd still use Eager Page
Splitting unconditionally though, first to split to 2M and then to
split to 4K.

Yes it was intentional, but I forgot to describe it in the commit
message. Good catch.

This tracepoint is redundant with the one in alloc_tdp_mmu_page().

I'll update the commit message for v1.

While I was writing this patch it got me wondering if we can do an
even more general refactor and replace root_hpa and shadow_root_level

Oh wow, thanks for catching that. You are correct. Will fix in v1.

Ack. I'll take a look and see if I can avoid the BUG_ONs. They're
optional sanity checks anyway.

I can change it to |= and add a comment. I prefer not to extra the PFN
and replace it since there's really no reason to. One of the nice
things about this function in general is that we don't have to
construct the child SPTE from scratch, we just have to slightly adjust
the parent SPTE. For the address, the address in the large SPTE is
already there, we just need to add in the offset to the lower-level
page.

Yes they are wasted right now. But there's a couple of things to keep in mind:

1. They are also wasted in every vCPU (in the per-vCPU caches) that
does not use the shadow MMU.
2. They will (I think) be used eventually when I add Eager Page
Splitting support to the shadow MMU.
3. split_caches is per-VM so it's only a few hundred bytes per VM.

If we really want to save the memory the right way forward might be to
make each kvm_mmu_memory_cache a pointer instead of an embedded
struct. Then we can allocate each dynamically only as needed. I can
add that to my TODO list but I don't think it'd be worth blocking this
on it given the points above.

IIUC, 1 here is just the min needed for kvm_mmu_topup_memory_cache to
return success. I chose 1 for each because it's the minimum necessary
to make forward progress (split one large page).

No matter what you pass for min kvm_mmu_topup_memory_cache() will
still always try to allocate KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE
objects.

Thanks for calling this out. Could the same be said about the existing
code that unconditionally tries to write-protect 2M+ pages? I aimed to
keep parity with the write-protection calls (always try to split
before write-protecting) but I agree there might be opportunities
available to skip altogether.

By the way, looking at this code again I think I see some potential bugs:
 - I don't think I ever free split_caches in the initially-all-set case.
 - What happens if splitting fails the CLEAR_LOG but succeeds the
CLEAR_LOG? We would end up propagating the write-protection on the 2M
page down to the 4K page. This might cause issues if using PML.

Gah, meant to say "first CLEAR_LOG" and "second CLEAR_LOG" here.

For TDP MUU, yes, as root_hpa == __pa(sp->spt) in all cases.  For the legacy/full
MMU, not without additional refactoring since root_hpa doesn't point at a kvm_mmu_page
when KVM shadows a non-paging guest with PAE paging (uses pae_root), or when KVM
shadows nested NPT and the guest is using fewer paging levels that the host (uses
pml5_root or pml4_root).

	if (mmu->shadow_root_level == PT64_ROOT_5LEVEL)
		mmu->root_hpa = __pa(mmu->pml5_root);
	else if (mmu->shadow_root_level == PT64_ROOT_4LEVEL)
		mmu->root_hpa = __pa(mmu->pml4_root);
	else
		mmu->root_hpa = __pa(mmu->pae_root);

That's definitely a solvable problem, e.g. it wouldn't be a problem to burn a few
kvm_mmu_page for the special root.  The biggest issue is probably the sheer amount
of code that would need to be updated.  I do think it would be a good change, but
I think we'd want to do it in a release that isn't expected to have many other MMU
changes.

shadow_root_level can also be replaced by mmu_role.base.level.  I've never bothered
to do the replacement because there's zero memory savings and it would undoubtedly
take me some time to retrain my brain :-)

The @min parameter is minimum number of pages that _must_ be available in the
cache, i.e. it's the maximum number of pages that can theoretically be used by
whatever upcoming operation is going to be consuming pages from the cache.

So '1' is technically correct, but I think it's the wrong choice given the behavior
of this code.  E.g. if there's 1 object in the cache, the initial top-up will do
nothing, and then tdp_mmu_split_large_pages_root() will almost immediately drop
mmu_lock to topup the cache.  Since the in-loop usage explicitly checks for an
empty cache, i.e. any non-zero @min will have identical behavior, I think it makes
sense to use KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE _and_ add a comment explaining why.

No, it will try to allocate KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE if and only if there
are fewer than @min objects in the cache.

This scenario will not happen though, since we free the caches after
splitting. So, the next time userspace enables dirty logging on a
memslot and we go to do the initial top-up the caches will have 0
objects.

If we set the min to KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE,
kvm_mmu_topup_memory_cache will return ENOMEM if it can't allocate at
least KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE objects, even though we really
only need 1 to make forward progress.

It's a total edge case but there could be a scenario where userspace
sets the cgroup memory limits so tight that we can't allocate
KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE objects when splitting the last few
pages and in the end we only needed 1 or 2 objects to finish
splitting. In this case we'd end up with a spurious pr_warn and may
not split the last few pages depending on which cache failed to get
topped up.

Yeah I never meant to block this series just for this. :)

If there's plan to move forward with shadow mmu support and they'll be needed
at last, then it's good to me to keep it as is.  Maybe before adding the shadow
mmu support we add a comment above the structure?  Depending on whether the
shadow mmu support is in schedule or not, I think.

IMHO when -ENOMEM happens, instead of keep trying with 1 shadow sp we should
just bail out even earlier.

Say, if we only have 10 (<40) pages left for shadow sp's use, we'd better make
good use of them lazily to be consumed in follow up page faults when the guest
accessed any of the huge pages, rather than we take them all over to split the
next continuous huge pages assuming it'll be helpful..

From that POV I have a slight preference over Sean's suggestion because that'll
make us fail earlier.  But I agree it shouldn't be a big deal.

They're different because wr-protect can be restored (to be not-wr-protected)
when vcpu threads write to the pages, so they need to be always done.

For huge page split - when it happened during dirty tracking it'll not be
recovered anymore, so it's a one-time thing.

So IMHO it's not about parity but it could be about how easy can it be
implemented, and whether it'll be worth it to add that complexity.

Besides the above accounting idea per-sp, we can have other ways to do this
too, e.g., keeping a bitmap showing which range has been split: that bitmap
will be 2M in granule for x86 because that'll be enough.  We init-all-ones for
the bitmap when start logging for a memslot.

But again maybe it turns out we don't really want that complexity.

IMHO a good start could be the perf numbers (which I asked in the cover letter)
comparing the overhead of 2nd+ iterations of CLEAR_LOG with/without eager page
split.

I saw that it's freed in kvm_mmu_try_split_large_pages(), no?

Hmm looks correct.. I'm wondering what will happen with that.

Firstly this should be rare as the 1st split should in 99% cases succeed.

Then if split failed at the 1st attempt, we wr-protected sptes even during pml
during the split.  When written, we'll go the fast page fault and record the
writes too, I think, as we'll apply dirty bit to the new spte so I think it'll
just skip pml.  Looks like we'll be using a mixture of pml+wp but all dirty
will still be captured as exptected?..

There could be leftover wp when stopping dirty logging, but that seems not
directly harmful too.  It'll make things a bit messed up, at least.

Isn't it a performance feature?  Why it'll be not safe?

Agreed, what I was thinking was not for public cloud usages, but for the cases
where we can do specific tunings on some specific scenarios.  It normally won't
matter a lot with small or medium sized VMs but extreme use cases.

Do you mean we'd also offer different granule dirty bitmap to the userspace
too?

I remembered you mentioned 2mb dirty tracking in your rfc series, but I didn't
expect it can be dynamically switched during tracking.  That sounds a very
intersting idea.

Hmm, in this particular case, I think using the caches is the wrong approach.  The
behavior of pre-filling the caches makes sense for vCPUs because faults may need
multiple objects and filling the cache ensures the entire fault can be handled
without dropping mmu_lock.  And any extra/unused objects can be used by future
faults.  For page splitting, neither of those really holds true.  If there are a
lot of pages to split, KVM will have to drop mmu_lock to refill the cache.  And if
there are few pages to split, or the caches are refilled toward the end of the walk,
KVM may end up with a pile of unused objects it needs to free.

Since this code already needs to handle failure, and more importantly, it's a
best-effort optimization, I think trying to use the caches is a square peg, round
hole scenario.

Rather than use the caches, we could do allocation 100% on-demand and never drop
mmu_lock to do allocation.  The one caveat is that direct reclaim would need to be
disallowed so that the allocation won't sleep.  That would mean that eager splitting
would fail under heavy memory pressure when it otherwise might succeed by reclaiming.
That would mean vCPUs get penalized as they'd need to do the splitting on fault and
potentially do direct reclaim as well.  It's not obvious that that would be a problem
in practice, e.g. the vCPU is probably already seeing a fair amount of disruption due
to memory pressure, and slowing down vCPUs might alleviate some of that pressure.

Not using the cache would also reduce the extra complexity, e.g. no need for
special mmu_cache handling or a variant of tdp_mmu_iter_cond_resched().

I'm thinking something like this (very incomplete):

I strongly object to this helper.  PRESENT in hardware and shadow-present are two
very different things, the name is_large_present_pte() doesn't capture that detail.
Yeah, we could name it is_large_shadow_present_pte(), but for me at least that
requires more effort to read, and it's not like this is replacing 10s of instances.

This can easily go on one line.

I don't think this helper should free the sp on failure, even if that's what all
paths end up doing.  When reading the calling code, it really looks like the sp
is being leaked because the allocation and free are in different contexts.  That
the sp is consumed on success is fairly intuitive given the "install" action, but
freeing on failure not so much.

And for the eager splitting, freeing on failure is wasteful.  It's extremely
unlikely to happen often, so in practice it's unlikely to be an issue, but it's
certainly odd since the loop is likely going to immediately allocate another sp,
either for the current spte or for the next spte.

Side topic, tdp_mmu_set_spte_atomic() and friends really should return 0/-EBUSY.
Boolean returns for errors usually end in tears sooner or later.

I would prefer we use hugepage when possible, mostly because that's the terminology
used by the kernel.  KVM is comically inconsistent, but if we make an effort to use
hugepage when adding new code, hopefully someday we'll have enough inertia to commit
fully to hugepage.

This should return a value.  If splitting succeeds, there should be no hugepages
and so walking the page tables to write-protect 2M is unnecessary.  Same for the
previous patch, although skipping the write-protect path is a little less
straightforward in that case.

This should be done when tdp_mmu_split_large_page_atomic() is introduced, otherwise
this series is effectively introducing a bug and then fixing it.  At a very quick
glance, I don't see anything that would prevent squashing this in.

In my mind "huge page" implies 2M and "large page" is generic to 2m
and 1g. (IDK if we settled on a name for 1G pages)
I've definitely been guilty of reinforcing this inconsistent
terminology. (Though it was consistent in my head, of course.) If we
want to pick one and use it everywhere, I'm happy to get onboard with
a standard terminology.

What about 4m PSE pages?  :-)

I'm mostly joking, but it does raise the point that trying to provide unique names
for each size is a bit of a fools errand, especially on non-x86 architectures that
support a broader variety of hugepage sizes.  IMO, the least ambiguous way to refer
to hugepages is to say that everything that isn't a 4k page (or whatever PAGE_SIZE
is on the architecture) is a hugepage, and then explicitly state the size of the
page if it matters.

I hear you on using "large page", I've had to undo a solid decade of "large page"
terminology from my pre-Linux days.  But for better or worse, the kernel uses
hugepage, e.g. hugetlbfs supports 1gb and 2mb pages.  I think we should follow
the kernel, especially since we have aspirations of unifying more of KVM's MMU
across multiple architectures.

Not necessarily. The vCPUs might be running just fine in the VM being
split because they are in their steady state and not faulting in any
new memory. (Memory pressure might be coming from another VM landing
on the host.)

IMO, if we have an opportunity to avoid doing direct reclaim in the
critical path of customer execution we should take it.

The on-demand approach will also increase the amount of time we have
to hold the MMU lock to page splitting. This is not too terrible for
the TDP MMU since we are holding the MMU lock in read mode, but is
going to become a problem when we add page splitting support for the
shadow MMU.

I do agree that the caches approach, as implemented, will inevitably
end up with a pile of unused objects at the end that need to be freed.
I'd be happy to take a look and see if there's anyway to reduce the
amount of unused objects at the end with a bit smarter top-up logic.

Heh, "safe" is a bit overzealous. But we've found that as the vCPU
count scales in VMs, not doing Eager Page Splitting leads to
unacceptable performance degradations (per customers), especially when
using the shadow MMU where hugepage write-protection faults are done
while holding the MMU lock in write mode. So from that perspective,
it's "unsafe" to skip Eager Page Splitting unless you are absolutely
sure the guest workload will not be doing much writes.

Perhaps. The 2M dirty tracking work is still in very early research
phases and the first version will likely not be so dynamic. But I
could imagine we eventually get to the point where we are doing some
hybrid approach.

Good point. I'll fix this in v1.

Agreed. I was sticking with local style here but would like to see
more of this code switch to returning ints. I'll take a look at
including that cleanup as well in v1, if not a separate pre-series.

Thanks for the explanation! I had a feeling this refactor would start

That's true for 4K pages, but not for write-protecting 2M+ pages
(which is what we're discussing here). Once KVM write-protects a 2M+
page, it should never need to write-protect it again, but we always
try to here. Same goes with splitting.

Ah yes you are right. I misremembered how I implemented it and thought
we kept the split_caches around across calls to CLEAR_LOG. (We
probably should TBH. The current implementation is quite wasteful.)

It's not just the extra objects, it's the overall complexity that bothers me.
Complexity isn't really the correct word, it's more that as written, the logic
is spread over several files and is disingenuous from the perspective that the
split_cache is in kvm->arch, which implies persistence, but the cache are
completely torn down after evey memslot split.

I suspect part of the problem is that the code is trying to plan for a future
where nested MMUs also support splitting large pages.  Usually I'm all for that
sort of thing, but in this case it creates a lot of APIs that should not exist,
either because the function is not needed at all, or because it's a helper buried
in tdp_mmu.c.  E.g. assert_split_caches_invariants() is overkill.

That's solvable by refactoring and shuffling code, but using kvm_mmu_memory_cache
still feels wrong.  The caches don't fully solve the might_sleep() problem since
the loop still has to drop mmu_lock purely because it needs to allocate memory,
and at the same time the caches are too agressive because we can theoretically get
false positives on OOM scenarios, e.g. a topup could fail when trying to allocate
25 objects, when only 1 is needed.  We could enhance the cache code, which is
pretty rudimentary, but it still feels forced.

One thing we can take advantage of is that remote TLB flushes can be deferred
until after all roots are done, and don't need to be serviced if mmu_lock is
dropped.  Changes from a hugepage to a collection of smaller pages is atomic, no
memory is freed, and there are no changes in gfn=>pfn made by the split.  If
something else comes along and modifies the newly created sp or its children,
then it will flush accordingly.  Similar to write-protecting the page, the only
requirement is that all vCPUs see the small pages before the ioctl() returns,
i.e. before userspace can query the dirty log.  Never needing to flush is one
less reason to use a variant of tdp_mmu_iter_cond_resched(). 

So, what if we do something like this?  Try to allocate on-demand without dropping
mmu_lock.  In the happy case, it will succeed and there's no need to drop mmu_lock.
If allocation fails, drop RCU and mmu_lock and retry with direct relcaim allowed.

Some ugly gotos to reduce indentation, there's probably a better way to dress
this up.  Comments obviously needed.  This also doesn't track whether or not a
flush is needed, that will sadly need to be an in/out param, assuming we want to
return success/failure.

I thought dropping the lock to allocate memory was a good thing. It
reduces the length of time we hold the RCU read lock and mmu_lock in
read mode. Plus it avoids the retry-with-reclaim and lets us reuse the
existing sp allocation code.

Eager page splitting itself does not need to be that performant since
it's not on the critical path of vCPU execution. But holding the MMU
lock can negatively affect vCPU performance.

But your preference is to allocate without dropping the lock when possible. Why?

This is why I picked a min of 1 for the cache top-up. But this would
be true if we increased the min beyond 1.

Good point. I'll revise the TLB flushing in v1 regardless.

It's not a simple reuse though, e.g. it needs new logic to detect when the caches
are empty, requires a variant of tdp_mmu_iter_cond_resched(), needs its own instance
of caches and thus initialization/destruction of the caches, etc...

Because they're two different things.  Lock contention is already handled by
tdp_mmu_iter_cond_resched().  If mmu_lock is not contended, holding it for a long
duration is a complete non-issue.

Dropping mmu_lock means restarting the walk at the root because a different task
may have zapped/changed upper level entries.  If every allocation is dropping
mmu_lock, that adds up to a lot of extra memory accesses, especially when using
5-level paging.

Batching allocations via mmu_caches mostly works around that problem, but IMO
it's more complex overall than the retry-on-failure approach because it bleeds
core details into several locations, e.g. the split logic needs to know intimate
details of kvm_mmu_memory_cache, and we end up with two (or one complex) versions
of tdp_mmu_iter_cond_resched().

In general, I also dislike relying on magic numbers (the capacity of the cache)
for performance.  At best, we have to justify the magic number, now and in the
future.  At worst, someone will have a use case that doesn't play nice with KVM's
chosen magic number and then we have to do more tuning, e.g. see the PTE prefetch
stuff where the magic number of '8' (well, 7) ran out of gas for modern usage.
I don't actually think tuning will be problematic for this case, but I'd rather
avoid the discussion entirely if possible.

I'm not completely opposed to using kvm_mmu_memory_cache to batch allocations,
but I think we should do so if and only if batching has measurably better
performance for things we care about.  E.g. if eager splitting takes n% longer
under heavy memory pressure, but vCPUs aren't impacted, do we care?

So I think you are positing that disabling reclaim will make the
allocations fast enough that the time between
tdp_mmu_iter_cond_resched checks will be acceptable. Is there really
no risk of long tail latency in kmem_cache_alloc() or
__get_free_page()? Even if it's rare, they will be common at scale.

This is why I'm being so hesitant, and prefer to avoid the problem
entirely by doing all allocations outside the lock. But I'm honestly
more than happy to be convinced otherwise and go with your approach.

Yep.

If there is a potentially long latency in __get_free_page(), then we're hosed no
matter what because per alloc_pages(), it's allowed in any context, including NMI,
IRQ, and Soft-IRQ.  I've no idea how often those contexts allocate, but I assume
it's not _that_ rare given the amount of stuff that networking does in Soft-IRQ
context, e.g. see the stack trace from commit 2620fe268e80, the use of PF_MEMALLOC,
the use of GFP_ATOMIC in napi_alloc_skb, etc...  Anb it's not just direct
allocations, e.g. anything that uses a radix tree or XArray will potentially
trigger allocation on insertion.

But I would be very, very surprised if alloc_pages() without GFP_DIRECT_RECLAIM
has a long tail latency, otherwise allocating from any atomic context would be
doomed.

Ah I see, that's fair point. :)

Yeah let's see how it goes with the numbers, I'd hope it's trivial to do both
wr-protect 2m and the split unconditionally, because for CLEAR_LOG the major
overhead should be walking the small pages instead, afaiu.

In that case I agree your approach should not introduce any more MMU
lock contention than the split_caches approach in practice, and will
require a lot less new code. I'll attempt to do some testing to
confirm, but assuming that goes fine I'll go with your approach in v1.

Thanks!

David, this is yours; basically, kvm_mmu_topup_memory_cache must be 
called outside the mmu_lock.

Ah, I see. kvm_arch_mmu_enable_log_dirty_pt_masked is called with
mmu_lock already held. I'll make sure to address this in v1. In theory
this should just go away when I switch away from using split_caches to
Sean's suggestion of allocating under the mmu_lock with reclaim
disabled.
