3 years agoOne major issue talked about in research papers is reducing the overhead
patrick [Sat, 6 Mar 2021 19:25:27 +0000 (19:25 +0000)]
One major issue talked about in research papers is reducing the overhead
of the IOVA allocation.  As far as I can see the current "best solution"
is to cache IOVA ranges in percpu magazines.  I don't think we have this
issue at all thanks to bus_dmamap_create(9).  The map is created ahead
of time, and we know the maximum size of the DMA transfer.  Since with
smmu(4) we have IOVA per domain, allocating IOVA 'early' is essentially
free.  But pagetable mapping also incurs a performance penalty, since we
allocate pagetable entry descriptors through pools.  Since we have the
IOVA early, we can allocate those early as well.  This allocation is a
bit more expensive though, but can be optimized further.

All this means that there is no allocation overhead in hot code paths.
The "only" thing remaining is assigning IOVA to the segments, adjusting
the pagetable mappings, and flushing the IOTLB on unload.  Maybe there's
a way to do a combined flush for NICs, because we give a list of mbufs
to the network stack and we could do the IOTLB invalidation only once
right before we hand over the mbuf list to the upper layers.

Turns out there are dhcp servers that ignore DHCPREQUEST messages when

Due to another bug dhcpleased would have exit through a fatal() in the
frontend process if he had waited long enough for a Rebooting -> Init
transition because we didn't deconfigure our IP address and thus
didn't close our UDP socket. Upon configuring a new IP address we would
open a new UDP socket send it to the frontend which would then fatal()
due to an unexpected fd passed in.

Aproporiate timings are rather underspecified in RFC 2131. Instead of
doing an exponential backoff up to 64 in the "Rebooting" and

transition into the "Init" state and deconfigure the IP when
appropriate.

3 years agoIntroduce an IOVA allocator instead of mapping pages 1:1. Mapping pages 1:1
patrick [Fri, 5 Mar 2021 00:55:45 +0000 (00:55 +0000)]
Introduce an IOVA allocator instead of mapping pages 1:1.  Mapping pages 1:1
obviously reduces the overhead of IOVA allocation, but instead you have the
problem of doubly mapped pages, and making sure a page is only unmapped once
the last user is gone.  My initial attempt, modeled after apldart(4), calls
the allocator for each segment.  Unfortunately this introduces a performance
penalty which reduces performance from around 700 Mbit/s to about 20 Mbit/s,
or even less, in a simple single stream tcpbench scenario.  Most mbufs from
userland seem to have at least 3 segments.  Calculating the needed IOVA space
upfront reduces this penalty.  IOVA allocation overhead could be reduced once
and for all if it is possible to reserve IOVA during bus_dmamap_create(9), as
it is only called upon creation and basically never for each DMA cycle.  This
needs some more thought.

With this we now put the pressure on the PTED pools instead.  Additionally, but
not part of this diff, percpu pools for the PTEDs seem to reduce the overhead
for that single stream tcpbench scenario to 0.3%.  Right now this means we're
hitting a different bottleneck, not related to the IOMMU.  The next bottleneck
will be discovered once forwarding is unlocked.  Though it should be possible
to benchmark the current implementation, and different designs, using a cycles
counter.

With IOVA allocation it's not easily possible to correlate memory passed to
bus_dmamem_map(9) with memory passed to bus_dmamap_load(9).  So far my code
try to use the same cachability attributes as the kenrel uses for its userland
mappings.  For the devices we support, there seems to be no need so far.  If
this ever gives us any trouble in the feature, I'll have a look and fix it.

While drivers should call bus_dmamap_unload(9) before bus_dmamap_destroy(9),
the API explicitly states that bus_dmamap_destroy(9) should unload the map
if it is still loaded.  Hence we need to do exactly that.  I actually have
found one network driver which behaves that way, and the developer intends
to change the network driver's behaviour.

Extend the commented code that shows which additional mappings are needed,
or which regions need to be reserved.  As it turns out, a region we should
not map is the PCIe address space.  Making a PCIe device try to do DMA to
an address in PCIe address space will obviously not make its way to SMMU
and host memory.  We'll probably have to add an API for that.

Original commit message:

Fix a deadlock between uvn_io() and uvn_flush(). While faulting on a
page backed by a vnode, uvn_io() will end up being called in order to
populate newly allocated pages using I/O on the backing vnode. Before
performing the I/O, newly allocated pages are flagged as busy by
uvn_get(), that is before uvn_io() tries to lock the vnode. Such pages
could then end up being flushed by uvn_flush() which already has
acquired the vnode lock. Since such pages are flagged as busy,
uvn_flush() will wait for them to be flagged as not busy. This will
never happens as uvn_io() cannot make progress until the vnode lock is
released.

Instead, grab the vnode lock before allocating and flagging pages as
busy in uvn_get(). This does extend the scope in uvn_get() in which the
vnode is locked but resolves the deadlock.
