1.0: initial release.
|
|
|
|
1.1: Various fixes:
|
|
|
|
+ Some tidying and culling of verbose output
|
|
|
|
+ CPU usage self-adjustment was usually wrong on multi-core machines, where
|
|
more than one CPU-jiffy may elapse per wallclock-jiffy. Fixed to account
|
|
for the number of detected CPUs, or --ncpus if given.
|
|
|
|
+ The CPU spinner's busy-wait loop was able to be optimized out on newer
|
|
GCC builds, and seemingly even by more recent x86_64 CPUs. Adjusted the
|
|
busy-waits to be less optimizable at the cost of some memory bus traffic.
|
|
|
|
+ If any child processes die, be more explicit about their exit status
|
|
|
|
+ Get HZ (used to compute jiffies/sec) from sysconf()
|
|
|
|
+ Get VM page size from sysconf()
|
|
|
|
+ Fix compilation warnings on x86_64
|
|
|
|
1.2: Two fixes:
|
|
|
|
+ CPU adjustments were not being properly retained across iterations, so
|
|
a verbose-level check identifying when proper sleep calibration had been
|
|
reached was never actually displayed; this did not affect proper
|
|
function.
|
|
|
|
+ Fix compilation under Debian Etch.
|
|
|
|
1.3: One fix:
|
|
|
|
+ Desired on-disk size was not being correctly passed to the disk stirrer
|
|
process, causing errors on little-endian systems with LFS support.
|
|
|
|
1.4: One fix:
|
|
|
|
+ Memory stirs greater than 4GB should work now, after fixes to non 64-bit
|
|
clean codepath.
|
|
+ v1.3 did not properly identify itself as such with --version
