Subject: [PATCH 00/27] Add KVM support for Book3s_64 (PPC64) hosts v6
Date: Fri, 30 Oct 2009 16:47:00 +0100 [thread overview]
Message-ID: <1256917647-6200-1-git-send-email-agraf@suse.de> (raw)
KVM for PowerPC only supports embedded cores at the moment.
While it makes sense to virtualize on small machines, it's even more fun
to do so on big boxes. So I figured we need KVM for PowerPC64 as well.
This patchset implements KVM support for Book3s_64 hosts and guest support
for Book3s_64 and G3/G4.
To really make use of this, you also need a recent version of qemu.
This time around I have no git tree to pull from. Sorry guys :-).
V1 -> V2:
- extend sregs with padding
- new naming scheme (ppc64 -> book3s_64; 74xx -> book3s_32)
- to_phys -> in-kernel tophys()
- loadimm -> LOAD_REG_IMMEDIATE
- call .ko kvm.ko
- set magic paca bit later
- run guest code with PACA->soft_enabled=true
- pt_regs for host state saving (guest too?)
- only do HV dcbz trick on 970
- refuse to run on LPAR because of missing SLB pieces
V2 -> V3:
- fix DAR/DSISR saving
- allow running on LPAR by modifying the SLB shadow
- change the SLB implementation to use a mem-backed cache and do
full world switch on enter/exit. gets rid of "context" magic
- be more aggressive about DEC injection
- remove fast ld/st because we're always in host context
- don't use SPRGs in real->paged transition
- implement dirty log
- remove MMIO speedup code
- SPRG cleanup
- rename SPRG3 -> SPRN_SPRG_PACA
- rename SPRG1 -> SPRN_SPRG_SCRATCH0
- don't use SPRG2
V3 -> V4:
- use context_id instead of mm_alloc
- export less
V4 -> V5:
- use get_tb instead of mftb
- make ppc32 and ppc64 emulation share more code
- make pvr 32 bits
- add patch to use hrtimer for decrememter
V5 -> V6:
- // -> /* */ style comments
- make code easier to read
- not take mmap_sem when it's not needed
