KVM: arm/arm64: Unify 32bit fault injection

2017-11-06T15:23:20Z

Both arm and arm64 implementations are capable of injecting faults, and yet have completely divergent implementations, leading to different bugs and reduced maintainability. Let's elect the arm64 version as the canonical one and move it into aarch32.c, which is common to both architectures.

arm: KVM: Add Virtual Abort injection helper

2016-09-08T10:53:00Z

Now that we're able to context switch the HCR.VA bit, let's introduce a helper that injects an Abort into a vcpu. Signed-off-by: Marc Zyngier Signed-off-by: Christoffer Dall

arm: KVM: Use common AArch32 conditional execution code

2016-09-08T10:53:00Z

Add the bit of glue and const-ification that is required to use the code inherited from the arm64 port, and move over to it. Signed-off-by: Marc Zyngier Signed-off-by: Christoffer Dall

arm64: KVM: Move the AArch32 conditional execution to common code

2016-09-08T10:53:00Z

It would make some sense to share the conditional execution code between 32 and 64bit. In order to achieve this, let's move that code to virt/kvm/arm/aarch32.c. While we're at it, drop a superfluous BUG_ON() that wasn't that useful. Following patches will migrate the 32bit port to that code base. Signed-off-by: Marc Zyngier Signed-off-by: Christoffer Dall

ARM: KVM: Move GP registers into the CPU context structure

2016-02-29T18:34:12Z

Continuing our rework of the CPU context, we now move the GP registers into the CPU context structure. Reviewed-by: Christoffer Dall Signed-off-by: Marc Zyngier

ARM: KVM: Move CP15 array into the CPU context structure

2016-02-29T18:34:12Z

Continuing our rework of the CPU context, we now move the CP15 array into the CPU context structure. As this causes quite a bit of churn, we introduce the vcpu_cp15() macro that abstract the location of the actual array. This will probably help next time we have to revisit that code.

ARM: KVM: Cleanup exception injection

2015-12-18T10:14:54Z

David Binderman reported that the exception injection code had a couple of unused variables lingering around. Upon examination, it looked like this code could do with an anticipated spring cleaning, which amounts to deduplicating the CPSR/SPSR update, and making it look a bit more like the architecture spec. The spurious variables are removed in the process. Reported-by: David Binderman Reviewed-by: Christoffer Dall Signed-off-by: Marc Zyngier
