KVM: PPC: Make use of hash based Shadow MMU

2010-08-01T07:47:28+00:00

We just introduced generic functions to handle shadow pages on PPC.
This patch makes the respective backends make use of them, getting
rid of a lot of duplicate code along the way.

KVM: PPC: Enable Book3S_32 KVM building

2010-05-17T09:18:54+00:00

Now that we have all the bits and pieces in place, let's enable building
of the Book3S_32 target.

KVM: PPC: Use KVM_BOOK3S_HANDLER

2010-05-17T09:18:28+00:00

So far we had a lot of conditional code on CONFIG_KVM_BOOK3S_64_HANDLER.
As we're moving towards common code between 32 and 64 bits, most of
these ifdefs can be moved to a more generic term define, called
CONFIG_KVM_BOOK3S_HANDLER.

This patch adds the new generic config option and moves ifdefs over.

KVM: PPC: Name generic 64-bit code generic

2010-05-17T09:18:14+00:00

We have quite some code that can be used by Book3S_32 and Book3S_64 alike,
so let's call it "Book3S" instead of "Book3S_64", so we can later on
use it from the 32 bit port too.

KVM: PPC: Implement Paired Single emulation

2010-04-25T09:35:27+00:00

The one big thing about the Gekko is paired singles.

Paired singles are an extension to the instruction set, that adds 32 single
precision floating point registers (qprs), some SPRs to modify the behavior
of paired singled operations and instructions to deal with qprs to the
instruction set.

Unfortunately, it also changes semantics of existing operations that affect
single values in FPRs. In most cases they get mirrored to the coresponding
QPR.

Thanks to that we need to emulate all FPU operations and all the new paired
single operations too.

In order to achieve that, we use the just introduced FPU call helpers to
call the real FPU whenever the guest wants to modify an FPR. Additionally
we also fix up the QPR values along the way.

That way we can execute paired single FPU operations without implementing a
soft fpu.

KVM: PPC: Add helpers to call FPU instructions

2010-04-25T09:35:15+00:00

To emulate paired single instructions, we need to be able to call FPU
operations from within the kernel. Since we don't want gcc to spill
arbitrary FPU code everywhere, we tell it to use a soft fpu.

Since we know we can really call the FPU in safe areas, let's also add
some calls that we can later use to actually execute real world FPU
operations on the host's FPU.

Include Book3s_64 target in buildsystem

2009-11-05T05:50:26+00:00

Now we have everything in place to be able to build KVM, so let's add it
as config option and in the Makefile.
