Hi,
These patches add a debug exception test in aarch64 KVM selftests while
also adding basic exception handling support.
The structure of the exception handling is based on its x86
counterpart.
Tests use the same calls to initialize exception handling and both
architectures allow tests to override the handler for a particular
vector, or (vector, ec) for synchronous exceptions in the arm64 case.
The debug test is similar to x86_64/debug_regs, except that the x86 one
controls the debugging from outside the VM. This proposed arm64 test
controls and handles debug exceptions from the inside.
Thanks,
Ricardo
v3 -> v4:
V3 was dropped because it was breaking x86 selftests builds (reported
by
the kernel test robot).
- rename vm_handle_exception to vm_install_sync_handler instead of
vm_install_vector_handlers. [Sean]
- use a single level of routing for exception handling. [Sean]
- fix issue in x86_64/sync_regs_test when switching to ucalls for
unhandled
exceptions reporting.
This looks good to me. If I can get an Ack from any of the x86
maintainers,
I'll queue the series.
Thanks,
M.
