tests: Use '+=' to add additional tests, not '='
The recent commit that added the prom-env-test accidentially
overwrote the check-qtest-ppc-y, check-qtest-ppc64-y and
check-qtest-sparc-y variables instead of extending them.

ppc / sparc: Add a tester for checking whether OpenBIOS runs successfully
Since the mac99 and g3beige PowerPC machines recently broke without being noticed, it would be good to have a tester for "make check" that detects such issues immediately. A simple way to test the firmware of these machines is to use the "-prom-env" parameter of QEMU. This parameter can be used to put some Forth code into the 'boot-command' firmware variable which then can signal success to the tester by writing a magic value to a known memory location. And since some of the Sparc machines are also using OpenBIOS, they are now tested with this prom-env-tester, too.

qht: add qht-bench, a performance benchmark
This serves as a performance benchmark as well as a stress test for QHT. We can tweak quite a number of things, including the number of resize threads and how frequently resizes are triggered. A performance comparison of QHT vs CLHT[1] and ck_hs[2] using this same benchmark program can be found here: http://imgur.com/a/0Bms4 The tests are run on a 64-core AMD Opteron 6376, pinning threads to cores favoring same-socket cores. For each run, qht-bench is invoked with: $ tests/qht-bench -d $duration -n $n -u $u -g $range , where $duration is in seconds, $n is the number of threads, $u is the update rate (0.0 to 100.0), and $range is the number of keys. Note that ck_hs's performance drops significantly as writes go up, since it requires an external lock (I used a ck_spinlock) around every write. Also, note that CLHT instead of using a seqlock, relies on an allocator that does not ever return the same address during the same read-critical section. This gives it a slight performance advantage over QHT on read-heavy workloads, since the seqlock writes aren't there. [1] CLHT: https://github.com/LPD-EPFL/CLHT https://infoscience.epfl.ch/record/207109/files/ascy_asplos15.pdf [2] ck_hs: http://concurrencykit.org/ http://backtrace.io/blog/blog/2015/03/13/workload-specialization/ A few of those plots are shown in text here, since that site might not be online forever.
