[PATCH v4 00/19] kvm-unit-tests/arm: initial drop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a v4 of a series that introduces arm to kvm-unit-tests. First,
it does some tidying up of the repo. Then, it adds support for device
trees (libfdt), and for virtio-testdev[1]. Next, it adds the basic
infrastructure for booting a test case (guest), and adds a first
test case, a self-test to confirm setup was completed successfully.
Finally, it further prepares the framework for more complicated tests
by adding vector support, and extends the self-test to test that too.

This initial drop doesn't require kvmarm. qemu-system-arm is enough,
but it must have mach-virt, and the virtio-testdev patch[1].

These patches (v4) are also available from a git repo here
https://github.com/rhdrjones/kvm-unit-tests/commits/arm/v4-initial-drop

The v3 patches are available for reference here
https://github.com/rhdrjones/kvm-unit-tests/commits/arm/v3-initial-drop

Major v3->v4 differences are noted in each patch that has some under
the '---'. There are also some new patches since v3 in this series,
and a few v3 patches were dropped.

Some more interesting v3->v4 changes are:
  * rebased to "7505ea2: realmode: make performance test run..."
  * generation of asm-offsets.h now done like Kbuild
  * cleaner build in general (new asm dir, no libfdt changes)
  * introduction of memregions
  * introduction of spinlocks
  * determination of nr_cpus on setup
  * reworked devicetree.[ch] to cleanup api and better document
  * a more general virtio_bind() implementation
  * more code comments and commit messages

Thanks in advance for reviews!
