+PowerPC guest does not emulate L2 and L3 cache for KVM vCPUs
+
+PowerPC KVM guest does not emulate L2 and L2 caches for vCPU, it would be good to have them enabled if not any known issues/limitation already with PowerPC.

+background: x86 enabling cpu L2 cache bydefault and L3 cache on demand for kvm guest
+and claims performance improvement as vcpus can be 
+benefited with lesser `vmexits due to guest send IPIs.` with L3 cache enabled, below was patch for same.

+The QEMU project is currently considering to move its bug tracking to
+another system. For this we need to know which bugs are still valid
+and which could be closed already. Thus we are setting older bugs to
+"Incomplete" now.
+
+If you still think this bug report here is valid, then please switch
+the state back to "New" within the next 60 days, otherwise this report
+will be marked as "Expired". Or please mark it as "Fix Released" if
+the problem has been solved with a newer version of QEMU already.
+
+Thank you and sorry for the inconvenience.
+
+[Expired for QEMU because there has been no activity for 60 days.]
