Review checklist for kvm patches
|
|
================================
|
|
|
|
1. The patch must follow Documentation/process/coding-style.rst and
|
|
Documentation/process/submitting-patches.rst.
|
|
|
|
2. Patches should be against kvm.git master branch.
|
|
|
|
3. If the patch introduces or modifies a new userspace API:
|
|
- the API must be documented in Documentation/virtual/kvm/api.txt
|
|
- the API must be discoverable using KVM_CHECK_EXTENSION
|
|
|
|
4. New state must include support for save/restore.
|
|
|
|
5. New features must default to off (userspace should explicitly request them).
|
|
Performance improvements can and should default to on.
|
|
|
|
6. New cpu features should be exposed via KVM_GET_SUPPORTED_CPUID2
|
|
|
|
7. Emulator changes should be accompanied by unit tests for qemu-kvm.git
|
|
kvm/test directory.
|
|
|
|
8. Changes should be vendor neutral when possible. Changes to common code
|
|
are better than duplicating changes to vendor code.
|
|
|
|
9. Similarly, prefer changes to arch independent code than to arch dependent
|
|
code.
|
|
|
|
10. User/kernel interfaces and guest/host interfaces must be 64-bit clean
|
|
(all variables and sizes naturally aligned on 64-bit; use specific types
|
|
only - u64 rather than ulong).
|
|
|
|
11. New guest visible features must either be documented in a hardware manual
|
|
or be accompanied by documentation.
|
|
|
|
12. Features must be robust against reset and kexec - for example, shared
|
|
host/guest memory must be unshared to prevent the host from writing to
|
|
guest memory that the guest has not reserved for this purpose.
