KVM: IA64: Carry non-ia64 changes into ia64

2013-04-26T18:27:27+00:00

We changed a few things in non-ia64 code paths. This patch blindly applies
the changes to the ia64 code as well, hoping it proves useful in case anyone
revives the ia64 kvm code.

KVM: Make KVM_PRIVATE_MEM_SLOTS optional

2012-12-14T01:21:58+00:00

Seems like everyone copied x86 and defined 4 private memory slots
that never actually get used.  Even x86 only uses 3 of the 4.  These
aren't exposed so there's no need to add padding.

KVM: Rename KVM_MEMORY_SLOTS -> KVM_USER_MEM_SLOTS

2012-12-14T01:21:57+00:00

It's easy to confuse KVM_MEMORY_SLOTS and KVM_MEM_SLOTS_NUM.  One is
the user accessible slots and the other is user + private.  Make this
more obvious.

KVM: Fix page-crossing MMIO

2012-04-19T23:35:07+00:00

MMIO that are split across a page boundary are currently broken - the
code does not expect to be aborted by the exit to userspace for the
first MMIO fragment.

This patch fixes the problem by generalizing the current code for handling
16-byte MMIOs to handle a number of "fragments", and changes the MMIO
code to create those fragments.

KVM: Factor out kvm_vcpu_kick to arch-generic code

2012-04-08T09:47:47+00:00

The kvm_vcpu_kick function performs roughly the same funcitonality on
most all architectures, so we shouldn't have separate copies.

PowerPC keeps a pointer to interchanging waitqueues on the vcpu_arch
structure and to accomodate this special need a
__KVM_HAVE_ARCH_VCPU_GET_WQ define and accompanying function
kvm_arch_vcpu_wq have been defined. For all other architectures this
is a generic inline that just returns &vcpu->wq;

KVM: Introduce kvm_memory_slot::arch and move lpage_info into it

2012-03-08T12:10:22+00:00

Some members of kvm_memory_slot are not used by every architecture.

This patch is the first step to make this difference clear by
introducing kvm_memory_slot::arch;  lpage_info is moved into it.

KVM: Clean up vm creation and release

2011-01-12T09:29:09+00:00

IA64 support forces us to abstract the allocation of the kvm structure.
But instead of mixing this up with arch-specific initialization and
doing the same on destruction, split both steps. This allows to move
generic destruction calls into generic code.

It also fixes error clean-up on failures of kvm_create_vm for IA64.

KVM: Remove unnecessary divide operations

2010-08-01T07:47:30+00:00

This patch converts unnecessary divide and modulo operations
in the KVM large page related code into logical operations.
This allows to convert gfn_t to u64 while not breaking 32
bit builds.
