Hello and thanks for having reported this issue.
Once the patch set 'Fix doorbell emulation for v2 API on PPC' with patches:
- arch/powerpc/kvm: Add DPDES support in helper library for Guest state buffer
- arch/powerpc/kvm: Fix doorbell emulation for v2 API
are upstream accepted (having them in 'linux-next' is sufficient), we can think
about picking them.
I cannot find them in 'linux-next' yet
(https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/?qt=grep&q=Fix+doorbell+emulation+for+v2+API),
but assume they are still part of a staging tree and will hit linux-next soon.
Based on your statement "The fix has been accepted upstream and will be
backported for kernels >= 6.7" I assume the patch(es) are (or will be soon)
also upstream marked as "stable updates", and will then land in kernel 6.8
(that we have in 24.04).
As soon as this happens, the "stable updates" for 6.8 will be picked by the
Canonical kernel team automatically.
