, where $n is the number of threads and $r is the allowed range for the additions.
The scenarios measured are:
- atomic: implements x86' ADDL with the atomic_add helper (i.e. this patchset)
- cmpxchg: implement x86' ADDL with a TCG loop using the cmpxchg helper
- master: before this patchset
Results sorted in ascending range, i.e. descending degree of contention.
Y axis is Throughput in Mops/s. Tests are run on an AMD machine with 64
Opteron 6376 cores.
For master I stopped measuring master after 8 threads, because there is little

e1000e: Don't zero out buffer address in rx descriptor
The e1000e emulation zeroes out any used rx descriptor and then writes a
completely newly constructed value there. By doing this, it doesn't only
update the write-back area of the descriptors (as it's supposed to do),
but it also clears the buffer address, which real hardware doesn't do.
The spec explicitly mentions in chapter 7.1.8 that it is valid for a
driver to reuse a descriptor and only update the status field while
doing so, i.e. reusing the old buffer address:
If software statically allocates buffers, and uses memory read to
check for completed descriptors, it simply has to zero the status
byte in the descriptor to make it ready for reuse by hardware.
This patch fixes the behaviour to leave the buffer address in
descriptors unchanged even after the descriptor has been used.

qdict: implement a qdict_crumple method for un-flattening a dict
The qdict_flatten() method will take a dict whose elements are
further nested dicts/lists and flatten them by concatenating
keys.
The qdict_crumple() method aims to do the reverse, taking a flat
qdict, and turning it into a set of nested dicts/lists. It will
apply nesting based on the key name, with a '.' indicating a
new level in the hierarchy. If the keys in the nested structure
are all numeric, it will create a list, otherwise it will create
a dict.
If the keys are a mixture of numeric and non-numeric, or the
numeric keys are not in strictly ascending order, an error will
be reported.
The intent of this function is that it allows a set of QemuOpts
to be turned into a nested data structure that mirrors the nesting
used when the same object is defined over QMP.

qapi: don't pass two copies of TestInputVisitorData to tests
The input_visitor_test_add() method was accepting an instance
of 'TestInputVisitorData' and passing it as the 'user_data'
parameter to test functions. The main 'TestInputVisitorData'
instance that was actually used, was meanwhile being allocated
automatically by the test framework fixture setup.
The 'user_data' parameter is going to be needed for tests
added in later patches, so getting rid of the current mistaken
usage now allows this.
