This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

KVM: Add coalesced MMIO support (powerpc part) 2008-07-20T09:42:31+00:00 Laurent Vivier Laurent.Vivier@bull.net 2008-05-30T14:05:56+00:00 588968b6b7d34e6a88f538d1db9aca47b203623e This patch enables coalesced MMIO for powerpc architecture. It defines KVM_MMIO_PAGE_OFFSET and KVM_CAP_COALESCED_MMIO. It enables the compilation of coalesced_mmio.c.

KVM: ppc: Handle guest idle by emulating MSR[WE] writes 2008-05-04T11:44:44+00:00 Hollis Blanchard hollisb@us.ibm.com 2008-04-25T22:55:49+00:00 45c5eb67da5a668abe79c23a7e64dbc87a600f90 This reduces host CPU usage when the guest is idle. However, the guest must set MSR[WE] in its idle loop, which Linux did not do until 2.6.26.

KVM: ppc: PowerPC 440 KVM implementation 2008-04-27T15:21:39+00:00 Hollis Blanchard hollisb@us.ibm.com 2008-04-17T04:28:09+00:00 bbf45ba57eaec56569918a8bab96ab653bd45ec1 This functionality is definitely experimental, but is capable of running unmodified PowerPC 440 Linux kernels as guests on a PowerPC 440 host. (Only tested with 440EP "Bamboo" guests so far, but with appropriate userspace support other SoC/board combinations should work.) See Documentation/powerpc/kvm_440.txt for technical details.
