 - [nasm](nasm/): Small unit tests written in assembly, which are run using gdb
   on the host.
-- [qemu](qemu/): Builds a Linux binary, which tests many CPU features, which
-  are then compared to a run on the host.
+- [qemu](qemu/): Based on tests from qemu. Builds a Linux binary, which tests

 - [kvm-unit-test](kvm-unit-test/): Based on tests from the KVM project, tests
   various CPU features.
 - [full](full/): Starts several OSes and checks if they boot correctly.
-- [perf-irhydra](perf-irhydra/): Manual performance test. Probably not
-  interesting for you.
+- [jit-paging](jit-paging/): Tests jit and paging interaction.
+- [api](api/): Tests for several API functions of v86.
+- [devices](devices/): Device tests.
+- [rust](rust/): Rust unit test helpers.
+- [expect](expect/): Expect tests for the jit output. Contains a set of
