perf_test_util is used to set up KVM selftests where vCPUs touch a region of memory. The guest code is implemented in perf_test_util.c (not the calling selftests). The guest code requires a 1 parameter, the vcpuid, which has to be set by calling vcpu_args_set(vm, vcpu_id, 1, vcpu_id). Today all of the selftests that use perf_test_util are making this call. Instead, perf_test_util should just do it. This will save some code but more importantly prevents mistakes since totally non-obvious that this needs to be called and failing to do so results in vCPUs not accessing the right regions of memory.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
