[RFC 0/2] Shrink page_frag_cache

[RFC 0/2] Shrink page_frag_cache

[Matthew Wilcox]

From: Matthew Wilcox <mawilcox@microsoft.com>

I've just learned about the page_frag_cache allocator, and now I want
to use it everywhere ;-)

But before I start using it in other places, I want to see if it can
be improved at all.  The pfmemalloc flag is pretty specific to how the
network stack uses it (with GFP_ATOMIC), and the pagecnt_bias is tricky
to understand.  I think we can do better by just using the fields in
struct page directly.  I don't have a suitable setup for performance
testing this code ... Alex, is there any chance you'd have time to give
this a spin?

[RFC 1/2] mm: Use page->mapping to indicate pfmemalloc

[Matthew Wilcox]

From: Matthew Wilcox <mawilcox@microsoft.com>

I want to use page->index for a different purpose, so move the pfmemalloc
indicator from page->index to page->mapping.

[RFC 2/2] page_frag_cache: Store metadata in struct page

[Matthew Wilcox]

From: Matthew Wilcox <mawilcox@microsoft.com>

Shrink page_frag_cache from 24 to 8 bytes (a single pointer to the
currently-in-use struct page) by using the page's refcount directly
(instead of maintaining a bias) and storing our current progress through
the page in the same bits currently used for page->index.  We no longer
need to reflect the page pfmemalloc state if we're storing the page
directly.

On the downside, we now call page_address() on every allocation, and we
do an atomic_inc() rather than a non-atomic decrement, but we should
touch the same number of cachelines and there is far less code (and
the code is less complex).

One point about storing metadata not in struct page was to avoid false sharing.

consumers of page frags call put_page() thus touching page refcount.

With the pagecnt_bias (and other fields) we store in another cache line 
(private to the producer) we amortize the access to the shared cache line only when needed.

So my concern with this patch is that it is essentially trading off
CPU performance for reduced size. One of the reasons for getting away
from using the page pointer is because it is expensive to access the
page when the ref_count is bouncing on multiple cache lines. In
addition converting from a page to a virtual address is actually more
expensive then you would think it should be. I went through and
optimized that the best I could, but there is still a pretty
significant cost to the call.

I won't be able to test the patches until next week, but I expect I
will probably see a noticeable regression when performing a small
packet routing test.

I'm not really interested in trading off SMP scalability for reduced
memory usage; if we see more than a trivial penalty then I'll withdraw
this RFC.  I read & understand the commits that you made to get us to
the current codebase, but there's no history of this particular variation
in the tree.

I think that by moving the 'offset' into the struct page, we end up updating
only one cacheline instead of two, which should be a performance win.
I understand your concern about the cacheline bouncing between the freeing
and allocating CPUs.  Is cross-CPU freeing a frequent occurrence?  From
looking at its current usage, it seemed like the allocation and freeing
were usually on the same CPU.

Were you able to break down where that cost occurred?  It looks
pretty cheap on x86-32 nohighmem:

I did code up a variant which stored the virtual address of the offset
in page->index, but I threw that away after seeing how much more code
it turned into.  Fortunately I had a better idea of how to implement that
early this morning.  I haven't even tested it yet, but it looks like better
generated code:

Obviously if the problem turns out to be the cacheline thrashing rather
than the call to page_to_virt, then this is pointless to test.

I really appreciate you being willing to try this for me.  I need to
get myself a dual-socket machine to test things like this.

Issue is cacheline thrashing indeed, particularly on PowerPC (64 KB pages)

While we/the-network-stack in many cases try to alloc and free on the
same CPU.  Then, in practical default setups it will be common case to
alloc and free on different CPUs.  The scheduler moves processes
between CPUs, and irqbalance change which CPU does the DMA TX
completion (in case of forwarding).  I usually pin/align the NIC IRQs
manually (via proc smp_affinity_list) and manually pin/taskset the
userspace process (and makes sure to test both local/remote alloc/free
cases when benchmarking).

I used to recommend people to pin the RX userspace process to the NAPI
RX CPU, but based on my benchmarking I no longer do that.  At least for
UDP (after Paolo Abeni's optimizations) then there is a significant
performance advantage of running UDP receiver on another CPU (in the
range from 800Kpps to 2200Kpps). (Plus it avoids the softirq starvation
problem).

Mellanox even have a perf tuning tool, that explicit moves the DMA
TX-completion IRQ to run on another CPU than RX. Thus, I assume that
they have evidence/benchmarks that show this as an advantage.

More recently I implemented XDP cpumap redirect.  Which explicitly
moves the raw page/frame to be handled on a remote CPU.  Mostly to move
another MM alloc/free overhead away from the RX-CPU, which is the SKB
alloc/free overhead.  I'm working on a XDP return frame API, but for
now, performance depend on the page_frag recycle tricks (although for
the sake of accuracy it doesn't directly depend on page_frag_cache API,
but similar pagecnt_bias tricks).

Agreed.

So I went to test the patches and it looks like I am running into
something similar to what the kbuild test robot was reporting.

For my test I was going to just do a simple routing setup with an igb
pf trying to route packets to a netns with a pair of VFs on two
different subnets. As soon as I brought the VFs up in the namespace
they crashed with the following errors:

I can try taking a look at it, but I am pretty swamped for the next
several days. I probably won't have any free time to really test
