This patch:
- Fixes some bugs with Windows. It is working again
- Fixes a long-time issue with Linux on some Intel CPUs that
would cause any attempt to load the driver to crash due to
the GDT being marked as read only, and the Linux APIs
for this will triple fault your system if these APIs are
not used very quickly (a bug that probably should be
reported to Linux).
- Fixes issues with how the fail logic worked. You can not
fail inside the fail handler. New integration tests were
added to ensure that this case works as expected. In
general, the hypervisor has less assembly, and should be
more robust as a result.
- Fixes how TLB flushing is done, and adds TLB flushing APIs.
A future PR will use this code to implement free_page and
free_huge.
- Continued work on removing the heap logic that is no longer
supported.
This patch provides
- A change to the way advance IP worked. It now also runs the
the VS.
- Added two new ABIs to support changing the active VM. This
allows exit handlers to determine which VM they want to
work with, without having to run the VM to make this change
occur
- Adds some sanity checks to some of the registers to ensure
they are configured properly by extensions.
This patch addresses the following:
- Adds a number of addition hypercall that are needed for MicroV
- Updates the code to support the changes made to the BSL including
better checking of safe integrals and narrow contracts
- Adds a lib folder to contain code shared between the kernel and
extensions where possible.
- Minor initial additions for Rust. Still lots of work to do here
