Johannes Berg a5d7da3fd3 hwsim tests: Prefill database in VM tests 
In some cases, e.g., with the VM tests if the VM crashes, it
can be useful to know which tests should have run but didn't
(or didn't finish). In order to catch these more easily, add
an option to prefill the database with all tests at the very
beginning of the testing (in a new NOTRUN state) and use the
option in the VM tests.

README 

These scripts allow you to run the hwsim tests inside a KVM virtual machine.

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.

Install the required tools: at least 'kvm', if you want tracing trace-cmd,
valgrind if you want, etc.

Compile the hwsim tests as per the instructions given, you may have to
install some extra development packages (e.g. binutils-dev for libbfd).

Create a vm-config file and put the KERNELDIR option into it (see the
vm-run.sh script). If you want valgrind, also increase the memory size.

Now you can run the vm-run.sh script and it will execute the tests using
your system's root filesystem (read-only) inside the VM. The options you
give it are passed through to run-all.sh, see there.
