This is the landing branch for the Krun Linux Kernel.
The Krun Linux kernel has additional system calls for low-latency access to several MSRs which Krun uses for benchmarking. Although the existing msr (and rmsr) modules provide access to MSRs via device nodes, they introduce too much jitter into measurements.
For more information on Krun, see: http://soft-dev.org/src/krun/
Binary releases of the Krun Linux Kernel can be found here.
The Krun Linux Kernel functionality is periodically ported to newer kernel versions. The following versions are currently available:
| Version | Branch |
|---|---|
| 3.16.36 | linux-3.16.36-krun |
| 4.9.0 | linux-4.9-krun |
| 4.9.30 | linux-4.9.30-krun |
| 4.9.88 | linux-4.9.88-krun |
Individual branches contain instructions on how to build from source.
