KVM: Add memory slot versioning and use it to provide fast guest write interface

2011-01-12T09:23:08+00:00

Keep track of memslots changes by keeping generation number in memslots
structure. Provide kvm_write_guest_cached() function that skips
gfn_to_hva() translation if memslots was not changed since previous
invocation.

KVM: Use u64 for frame data types

2010-08-02T03:39:44+00:00

For 32bit machines where the physical address width is
larger than the virtual address width the frame number types
in KVM may overflow. Fix this by changing them to u64.

KVM: Move struct kvm_pio_request into x86 kvm_host.h

2009-03-24T09:02:55+00:00

This is an x86 specific stucture and has no business living in common code.

KVM: remove the vmap usage

2009-03-24T09:02:54+00:00

vmap() on guest pages hides those pages from the Linux mm for an extended
(userspace determined) amount of time.  Get rid of it.

KVM: MMU: Don't assume struct page for x86

2008-04-27T09:01:15+00:00

This patch introduces a gfn_to_pfn() function and corresponding functions like
kvm_release_pfn_dirty().  Using these new functions, we can modify the x86
MMU to no longer assume that it can always get a struct page for any given gfn.

We don't want to eliminate gfn_to_page() entirely because a number of places
assume they can do gfn_to_page() and then kmap() the results.  When we support
IO memory, gfn_to_page() will fail for IO pages although gfn_to_pfn() will
succeed.

This does not implement support for avoiding reference counting for reserved
RAM or for IO memory.  However, it should make those things pretty straight
forward.

Since we're only introducing new common symbols, I don't think it will break
the non-x86 architectures but I haven't tested those.  I've tested Intel,
AMD, NPT, and hugetlbfs with Windows and Linux guests.

KVM: Move arch dependent files to new directory arch/x86/kvm/

2008-01-30T16:01:18+00:00

This paves the way for multiple architecture support.  Note that while
ioapic.c could potentially be shared with ia64, it is also moved.
