arm: KVM: Handle async aborts delivered while at HYP

2016-09-08T10:53:00+00:00

Just like for arm64, we can handle asynchronous aborts being delivered at HYP while being caused by the guest. We use the exact same method to catch such an abort, and soldier on. Signed-off-by: Marc Zyngier Signed-off-by: Christoffer Dall

ARM: KVM: Add VFP lazy save/restore handler

2016-02-29T18:34:14+00:00

Similar to the arm64 version, add the code that deals with VFP traps, re-enabling VFP, save/restoring the registers and resuming the guest. Reviewed-by: Christoffer Dall Signed-off-by: Marc Zyngier

ARM: KVM: Add guest entry code

2016-02-29T18:34:13+00:00

Add the very minimal piece of code that is now required to jump into the guest (and return from it). This code is only concerned with save/restoring the USR registers (r0-r12+lr for the guest, r4-r12+lr for the host), as everything else is dealt with in C (VFP is another matter though).
