* kvm: introduce kvm_arch_msi_data_to_gsiEric Auger2015-06-021-0/+5
| | | | | | | | | | | On ARM the MSI data corresponds to the shared peripheral interrupt (SPI) ID. This latter equals to the SPI index + 32. to retrieve the SPI index, matching the gsi, an architecture specific function is introduced.

* kvm: add support for memory transaction attributesPaolo Bonzini2015-04-301-1/+3
| | | | | | | Let kvm_arch_post_run convert fields in the kvm_run struct to MemTxAttrs. These are then passed to address_space_rw. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* kvm: extend kvm_irqchip_add_msi_route to work on s390Frank Blaschka2015-01-121-0/+6
| | | | | | | | | | | on s390 MSI-X irqs are presented as thin or adapter interrupts for this we have to reorganize the routing entry to contain valid information for the adapter interrupt code on s390. To minimize impact on existing code we introduce an architecture function to fixup the routing entry.

* mips/kvm: Disable FPU on reset with KVMJames Hogan2014-07-091-0/+7
| | | | | | | | | | | | | | | | KVM doesn't yet support the MIPS FPU, or writing to the guest's Config1 register which contains the FPU implemented bit. Clear QEMU's version of that bit on reset and display a warning that the FPU has been disabled. The previous incorrect Config1 CP0 register value wasn't being passed to KVM yet, however we should ensure it is set correctly now to reduce the risk of breaking migration/loadvm to a future version of QEMU/Linux that does support it.
