These scripts allow you to run the hwsim tests inside a KVM virtual machine.
These scripts allow you to run the hwsim tests inside a KVM virtual machine or
as a UML (User Mode Linux) program.
To set it up, first compile a kernel with the kernel-config file as the
.config. You can adjust it as needed, the configuration is for a 64-bit
x86 system and should be close to minimal. The architecture must be the
same as your host since the host's filesystem is used.
To set it up, first compile a kernel with the kernel-config[.uml] file as the
.config. You can adjust it as needed, the configuration is for a 64-bit x86
system and should be close to minimal. The architecture must be the same as
your host since the host's filesystem is used.
To build the regular x86_64 kernel, simply issue
yes "" | make -j <n_cpus>
or to build UML:
yes "" | ARCH=um make -j <n_cpus>
Running a UML kernel is recommended as it can optimize out any sleep()s or
kernel timers by taking advantage of UML time travel mode, greatly increasing
test efficiency (~3200 tests can be run in under 5 minutes using parallel-vm.py
on a 24 core CPU).
Install the required tools: at least 'kvm', if you want tracing trace-cmd,
valgrind if you want, etc.
