After a long period of development we are happy to release Klever 1.0! This major version is dedicated to verification of Linux loadable kernel modules. Klever 2.0 will allow users to verify various C software.
Klever 1.0 includes all issues scheduled for 0.3 since they take much more time than we expected (we did not release 0.3 at all). Besides, there are many other fixes and improvements. We would like to mention the most valuable ones:
- Verification results processing, visualization and assessment:
- More accurate calculation and more pretty visualization of a verification job decision progress.
- Adding more means for unknown report marks.
- Improving error traces representation.
- Updating the CPAchecker verification back-end.
- Deployment:
- Developing scripts for local deployment of Klever at Debian 9.
- Improving deployment within OpenStack clouds.
- Creating documentation that describes Klever deployment.
- Support of a command-line interface for Klever Bridge.
- Continuous integration:
- Considerable enhancement of Klever tests.
- Evaluating testing and validation results with preset marks.
- Automated regression testing with help of Jenkins.
- Numerous improvements, optimizations and bug fixes that substantially contribute reliability, increase performance and facilitate manual operations. Too many issues to treat them individually.
We thank all the developers and contributors for this great work! Before releasing Klever 2.0 we are going to release at least one minor version 1.1 with many valuable things but without any fundamental changes.
MicroTESK for RISC-V 0.0.4 has been released:
- Specifications: Support for
RV32C and RV64C
- Specifications: Bug fixes
- Test Templates: RISC-V validation tests
rv32uc/rvc and rv64uc/rvc
- Test Templates: Test templates are split into groups being located in separate folders
- Tests: Test suite uses QEMU4V 0.1.1
MicroTESK for RISC-V can be downloaded from http://forge.ispras.ru/projects/microtesk-riscv/files
We are happy to announce the first build of the QEMU4V tool.
QEMU4V ("QEMU for Verification") is an open source emulator for assembler programs that is based on QEMU project. The tool performs emulation for programs of several hardware architectures and provides some features (tracing, etc.) for system verification of microprocessors.
This build is based on 2.12.0 version of the QEMU emulator and includes all the features of QEMU for ARMv8 and QEMU for RISC-V tools.
