2016-03-24ppc: Add macros to register hypervisor mode SPRsBenjamin Herrenschmidt
The current set of spr_register_* macros only take the user and supervisor function pointers. To make the transition easy, we don't change that but we add "_hv" variants that can be used to register all 3 sets. To simplify the transition, users of the "old" macro will set the hypervisor callback to be the same as the supervisor one. The new registration function only needs to be used for registers that are either hypervisor only or behave differently in HV mode.

2016-03-24spapr/target-ppc/kvm: Only add hcall-instructions if KVM supports itAlexey Kardashevskiy
ePAPR defines "hcall-instructions" device-tree property which contains code to call hypercalls in ePAPR paravirtualized guests. In general pseries guests won't use this property, instead using the PAPR defined hypercall interface. However, this property has been re-used to implement a hack to allow PR KVM to run (slightly modified) guests in some situations where it otherwise wouldn't be able to (because the system's L0 hypervisor doesn't forward the PAPR hypercalls to the PR KVM kernel). Hence, this property is always present in the device tree for pseries guests. All KVM guests use it at least to read features via the KVM_HC_FEATURES hypercall. The property is populated by the code returned from the KVM's KVM_PPC_GET_PVINFO ioctl; if not implemented in the KVM, QEMU supplies code which will fail all hypercall attempts. If QEMU does not create the property, and the guest kernel is compiled with CONFIG_EPAPR_PARAVIRT (which is normally the case), there is exactly the same stub at @epapr_hypercall_start already. Rather than maintaining this fairly useless stub implementation, it makes more sense not to create the property in the device tree in the first place if the host kernel does not implement it. This changes kvmppc_get_hypercall() to return 1 if the host kernel does not implement KVM_CAP_PPC_GET_PVINFO. The caller can use it to decide on whether to create the property or not. This changes the pseries machine to not create the property if KVM does not implement KVM_PPC_GET_PVINFO. In practice this means that from now on the property will not be created if either HV KVM or TCG is used.

MIPS Release 6 and MIPS SIMD Architecture make it mandatory to have IEEE 754-2008 FPU which is indicated by CP1 FIR.HAS2008, FCSR.ABS2008 and FCSR.NAN2008 bits set to 1. In QEMU we still keep these bits cleared as there is no 2008-NaN support. However, this now causes problems preventing from running R6 Linux with the v4.5 kernel. Kernel refuses to execute 2008-NaN ELFs on a CPU whose FPU does not support 2008-NaN encoding: (...) VFS: Mounted root (ext4 filesystem) readonly on device 8:0. devtmpfs: mounted Freeing unused kernel memory: 256K (ffffffff806f0000 - ffffffff80730000) request_module: runaway loop modprobe binfmt-464c Starting init: /sbin/init exists but couldn't execute it (error -8) request_module: runaway loop modprobe binfmt-464c Starting init: /bin/sh exists but couldn't execute it (error -8) Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance. Therefore always indicate presence of 2008-NaN support in R6 as well as in R5+MSA CPUs, even though this feature is not yet supported by MIPS in QEMU.
