vfio: skip DMA map failure if already mapped

Currently vfio DMA map function will fail in case the same memory
segment is mapped twice.

This is too strict, as this is not an error to map the same memory
twice.

Instead, use the kernel return value to detect such state and have the
DMA function to return as successful.

For type1 mapping the kernel driver returns EEXISTS.
For spapr mapping EBUSY is returned since kernel 4.10.

5 years agoring: enforce reading tail before slots
Gavin Hu [Tue, 12 Mar 2019 16:58:53 +0000 (00:58 +0800)]
ring: enforce reading tail before slots

In weak memory models, like arm64, reading the prod.tail may get
reordered after reading the ring slots, which corrupts the ring and
stale data is observed.

This issue was reported by NXP on 8-A72 DPAA2 board. The problem is most
likely caused by missing the acquire semantics when reading
prod.tail (in SC dequeue) which makes it possible to read a
stale value from the ring slots.

For MP (and MC) case, rte_atomic32_cmpset() already provides the required
ordering. For SP case, the control depependency between if-statement (which
depends on the read of r->cons.tail) and the later stores to the ring slots
make RMB unnecessary. About the control dependency, read more at:
https://www.cl.cam.ac.uk/~pes20/ppc-supplemental/test7.pdf

This patch is adding the required read barrier to prevent reading the ring
slots get reordered before reading prod.tail for SC case.

the case - while *resized* area will be on the same NUMA node,

build: use version number from config file

Since we have the version number in a separate file at the root level,
we should not need to duplicate this in rte_version.h too. Best
approach here is to move the macros for specifying the year/month/etc.
parts from the version header file to the build config file - leaving
the other utility macros for e.g. printing the version string, where they
are.

For "make", this is done by having a little bit of awk parse the version
file and pass the results through to the preprocessor for the config
generation stage.

For "meson", this is done by parsing the version and adding it to the
standard dpdk_conf object.

In both cases, we need to append a large number - in this case "99",
previously 16 in original code - to the version number when we want to do
version number comparisons. Without this, the release version e.g. 19.05.0
will compare as less than it's RC's e.g. 19.05.0-rc4. With it, the

developer repositories and perform actions.  One of these services is
Travis-CI, a simple continuous integration platform.

This series introduces the ability for any github mirrors of the DPDK

travis CI infrastructure.  For now, this just means compilation - no
other kinds of automated run exists yet.  In the future, this can be
expanded to execute and report results for any test-suites that might
exist.

This is a simple initial implementation of a travis build for the DPDK
project.  It doesn't require any changes from individual developers to
enable, but will allow those developers who opt-in to GitHub and the
travis service to get automatic builds for every push they make.

compress/qat: add fallback to fixed compression

This patch adds fallback to fixed compression
feature during dynamic compression, when the input data size
is greater than IM buffer size / 1.1. This feature doesn't
stop compression proccess when IM buffer can be too small
to handle produced data.

5 years agocryptodev: restore crypto op alignment and layout
Konstantin Ananyev [Thu, 7 Mar 2019 14:13:14 +0000 (14:13 +0000)]
cryptodev: restore crypto op alignment and layout

in 18.08 new cache-aligned structure rte_crypto_asym_op was introduced.
As it also was included into rte_crypto_op, it caused implicit change
in rte_crypto_op layout and alignment: now rte_crypto_op is cache-line
aligned has a hole of 40/104 bytes between phys_addr and sym/asym op.
It looks like unintended ABI breakage, plus such change can cause
negative performance effects:
- now status and sym[0].m_src lies on different cache-lines, so
  post-process code would need extra cache-line read.
- new alignment causes grow of the space requirements and cache-line
  reads/updates for structures that contain rte_crypto_op inside.
As there seems no actual need to have rte_crypto_asym_op cache-line
aligned, and rte_crypto_asym_op is not intended to be used on it's own -
the simplest fix is just to remove cache-line alignment for it.
As the immediate positive effect: on IA ipsec-secgw performance increased
by 5-10% (depending on the crypto-dev and algo used).
My guess that on machines with 128B cache-line and lookaside-protocol
capable crypto devices the impact will be even more noticeable.
