When in split mode, instruction relocation and data relocation are not equal. So far we implemented this mode by reserving a special pseudo-VSID for the two cases and flushing all PTEs when going into split mode, which is slow. Unfortunately 32bit Linux and Mac OS X use split mode extensively. So to not slow down things too much, I came up with a different idea: Mark the split mode with a bit in the VSID and then treat it like any other segment. This means we can just flush the shadow segment cache, but keep the PTEs intact. I verified that this works with ppc32 Linux and Mac OS X 10.4 guests and does speed them up.

There are some pieces in the code that I overlooked that still use u64s instead of longs. This slows down 32 bit hosts unnecessarily, so let's just move them to ulong. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAvi Kivity <avi@redhat.com>

Some code we had so far required defines and had code that was completely Book3S_64 specific. Since we now opened book3s.c to Book3S_32 too, we need to take care of these pieces. So let's add some minor code where it makes sense to not go the Book3S_64 code paths and add compat defines on others.

This patch makes the VSID of mapped pages always reflecting all special cases we have, like split mode. It also changes the tlbie mask to 0x0ffff000 according to the spec. The mask we used before was incorrect. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAvi Kivity <avi@redhat.com>

There's a typo in the debug ifdef of the book3s_32 mmu emulation. While trying to debug something I stumbled across that and wanted to save anyone after me (or myself later) from having to debug that again. So let's fix the ifdef.

This patch adds an implementation for a G3/G4 MMU, so we can run G3 and G4 guests in KVM on Book3s_64. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>
