From 4e9200a0a0f89ad2b26f6aa42e1fca16b364a8c8 Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Tue, 1 Nov 2011 09:57:52 +0000 Subject: PPC: monitor: add ability to dump SLB entries When run with a PPC Book3S (server) CPU Currently 'info tlb' in the qemu monitor reports "dump_mmu: unimplemented". However, during bringup work, it can be quite handy to have the SLB entries, which are available in the CPUPPCState. This patch adds an implementation of info tlb for book3s, which dumps the SLB.
