The PAPI 4.1.1 release is now available for download. This is a minor
release of PAPI-C. It addresses a number of bugs and other issues that
have surfaced since the 4.1.0 release. See the software page to download the tarball.
This version fixes an issue in which 'make clean' would go into an
infinite loop searching for the doc directory. It also implements a
better mechanism for insuring that threads in linux kernels get their
own interrupts for perf_events. Various features are now enabled or
disabled at runtime based on kernel versioning, and support for the
perf-counter interface in linux kernel 2.6.31 has been deprecated in
favor of the perf-events interface in kernel 2.6.32 and above.
Support for the perf-events interface built into recent linux kernels has been strengthened and broadened.
In addition a number of corner cases in the test code have been
examined and addressed. A WARNING state was implemented for the tests,
to allow information to be provided without actually FAILing the test.
