2013-10-02	KVM: ARM: Fix typo in comments of inject_abt()	Anup Patel	1	-1/+1
	Very minor typo in comments of inject_abt() when we update fault status register for injecting prefetch abort. Signed-off-by: Anup Patel <anup.patel@linaro.org> Signed-off-by: Pranavkumar Sawargaonkar <pranavkumar@linaro.org> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2013-03-07	ARM: KVM: move kvm_handle_wfi to handle_exit.c	Marc Zyngier	1	-16/+0
	It has little to do in emulate.c these days... Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2013-03-07	ARM: KVM: move kvm_condition_valid to emulate.c	Marc Zyngier	1	-0/+45
	This is really hardware emulation, and as such it better be with its little friends. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2013-03-07	ARM: KVM: convert GP registers from u32 to unsigned long	Marc Zyngier	1	-11/+11
	On 32bit ARM, unsigned long is guaranteed to be a 32bit quantity. On 64bit ARM, it is a 64bit quantity. In order to be able to share code between the two architectures, convert the registers to be unsigned long, so the core code can be oblivious of the change.

2013-01-23	KVM: ARM: Emulation framework and CP15 emulation	Christoffer Dall	1	-0/+218
	Adds a new important function in the main KVM/ARM code called handle_exit() which is called from kvm_arch_vcpu_ioctl_run() on returns from guest execution. This function examines the Hyp-Syndrome-Register (HSR), which contains information telling KVM what caused the exit from the guest. Some of the reasons for an exit are CP15 accesses, which are not allowed from the guest and this commit handles these exits by emulating the intended operation in software and skipping the guest instruction. Minor notes about the coproc register reset: 1) We reserve a value of 0 as an invalid cp15 offset, to catch bugs in our table, at cost of 4 bytes per vcpu. 2) Added comments on the table indicating how we handle each register, for simplicity of understanding.

2013-01-23	KVM: ARM: Initial skeleton to compile KVM support	Christoffer Dall	1	-0/+155
	Targets KVM support for Cortex A-15 processors. Contains all the framework components, make files, header files, some tracing functionality, and basic user space API. Only supported core is Cortex-A15 for now. Most functionality is in arch/arm/kvm/* or arch/arm/include/asm/kvm_*.h.
