Hello Linus!
Here are the target updates for the v3.12-rc1 merge window.
Please go ahead and pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next
Lots of activity again this round for I/O performance optimizations
(per-cpu IDA pre-allocation for vhost + iscsi/target), and the addition
of new fabric independent features to target-core (COMPARE_AND_WRITE +
EXTENDED_COPY).
The main highlights include:
- Support for iscsi-target login multiplexing across individual network
portals
- Generic Per-cpu IDA logic (kent + akpm + clameter)
- Conversion of vhost to use per-cpu IDA pre-allocation for descriptors,
SGLs and userspace page pointer list
- Conversion of iscsi-target + iser-target to use per-cpu IDA pre-allocation
for descriptors
- Add support for generic COMPARE_AND_WRITE (AtomicTestandSet) emulation for
virtual backend drivers
- Add support for generic EXTENDED_COPY (CopyOffload) emulation for virtual
backend drivers.
- Add support for fast memory registration mode to iser-target (Vu)
The patches to add COMPARE_AND_WRITE and EXTENDED_COPY support are of
particular significance, which make us the first and only open source
target to support the full set of VAAI primitives.
Currently Linux clients are lacking upstream support to actually utilize
these primitives. However, with server side support now in place for
folks like MKP + ZAB working on the client, this logic once reserved for
the highest end of storage arrays, can now be run in VMs on their
laptops.
:-)
Thank you,
