One exception though: if the host only supports XIVE, we still # want to boot so we ignore xive=off. # # Similarly, have the spapr XIVE init code to looking at the interrupt # mode negotiated during CAS, and ignore xive=off if the hypervisor only # supports XIVE. # # Fixes: eac1e731b59e ("powerpc/xive: guest exploitation of the XIVE interrupt controller") # Cc: stable@vger.kernel.org # v4.20 # Reported-by: Pavithra R.
