FEDORA-2020-740479e5ec created by thl 3 months ago for Fedora 32
obsolete

Version 0.9.0 is a major rework with quite a number of important changes and new features. These are the highlights, see below for details:

  • kcbench now supports building a configuration generated with make allmodconfig
  • compiling with gcc10 and clang (with or without LLVM=1) are now supported
  • kcbench will now default to compiling Linux 5.7 for gcc10, clang10, and all compilers it does not recognize
  • a totally new approach for finding the optimal number of jobs that kcbench will use when compiling the kernel (make -j #), as measurements showed some systems (like an AMD Threadripper that was tested) compile the kernel quicker if SMT (aka HT/Hyper-Threading) is not used (see below and the man page for details)
  • the old and slightly unintuitive “kcbench points” result was dropped; instead show a "rate per hour" value for speed runs
  • kcbench now prints more details about the system before starting to measure, including the CPUfreq driver and governor
  • quite a few command line options and were changed to make usage more intuitive and consistent; some defaults have changed, too
  • kcbench finally has a Makefile for installing
  • the man page was improved quite a lot
  • handle errors during compilation more efficiently and show the output from make by default
  • cross-compilation is now support (still experimental!)
  • besides compiling one kernel really quick kcbench now supports a mode called “rate-run” (aka “kernbenchrate”), where it compiles multiple kernels in parallel (still experimental!) to keep all CPU cores busy all the time.
