2011-10-30pseries: Add device tree properties for VMX/VSX and DFP under kvmDavid Gibson
Sufficiently recent PAPR specifications define properties "ibm,vmx" and "ibm,dfp" on the CPU node which advertise whether the VMX vector extensions (or the later VSX version) and/or the Decimal Floating Point operations from IBM's recent POWER CPUs are available. Currently we do not put these in the guest device tree and the guest kernel will consequently assume they are not available. This is good, because they are not supported under TCG. VMX is similar enough to Altivec that it might be trivial to support, but VSX and DFP would both require significant work to support in TCG. However, when running under kvm on a host which supports these instructions, there's no reason not to let the guest use them. This patch, therefore, checks for the relevant support on the host CPU and, if present, advertises them to the guest as well.

2011-10-30ppc: Generalize the kvmppc_get_clockfreq() functionDavid Gibson
Currently the kvmppc_get_clockfreq() function reads the host's clock frequency from /proc/device-tree, which is useful to past to the guest in KVM setups. However, there are some other host properties advertised in the device tree which can also be relevant to the guests. This patch, therefore, replaces kvmppc_get_clockfreq() which can retrieve any named, single integer property from the host device tree's CPU node.

SPE instructions are defined by pairs. Currently, the invalid-bits mask is set for the first instruction, but the second one can have a different mask. example: GEN_SPE(efdcmpeq, efdcfs, 0x17, 0x0B, 0x00600000, 0x00180000, PPC_SPE_DOUBLE), Signed-off-by: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-10-30pseries: Update SLOF firmware imageDavid Gibson
This patch updates the SLOF submodule and precompiled image. The new SLOF versions contains two changes of note: * The previous SLOF has a bug in SCSI condition handling that was exposed by recent updates to qemu's SCSI emulation. This update fixes the bug. * The previous SLOF has a bug in its addressing of SCSI devices, which can be exposed under certain conditions. The new SLOF also fixes this.

2011-10-30pseries: Use Book3S-HV TCE acceleration capabilitiesDavid Gibson
The pseries machine of qemu implements the TCE mechanism used as a virtual IOMMU for the PAPR defined virtual IO devices. Because the PAPR spec only defines a small DMA address space, the guest VIO drivers need to update TCE mappings very frequently - the virtual network device is particularly bad. This means many slow exits to qemu to emulate the H_PUT_TCE hypercall. Sufficiently recent kernels allow this to be mitigated by implementing H_PUT_TCE in the host kernel. To make use of this, however, qemu needs to initialize the necessary TCE tables, and map them into itself so that the VIO device implementations can retrieve the mappings when they access guest memory (which is treated as a virtual DMA operation). This patch adds the necessary calls to use the KVM TCE acceleration. If the kernel does not support acceleration, or there is some other error creating the accelerated TCE table, then it will still fall back to full userspace TCE implementation.

2011-10-30pseries: Allow KVM Book3S-HV on PPC970 CPUSDavid Gibson
At present, using the hypervisor aware Book3S-HV KVM will only work with qemu on POWER7 CPUs. PPC970 CPUs also have hypervisor capability, but they lack the VRMA feature which makes assigning guest memory easier. In order to allow KVM Book3S-HV on PPC970, we need to specially allocate the first chunk of guest memory (the "Real Mode Area" or RMA), so that it is physically contiguous. Sufficiently recent host kernels allow such contiguous RMAs to be allocated, with a kvm capability advertising whether the feature is available and/or necessary on this hardware. This patch enables qemu to use this support, thus allowing kvm acceleration of pseries qemu machines on PPC970 hardware.

2011-10-30pseries: Support SMT systems for KVM Book3S-HVDavid Gibson
Alex Graf has already made qemu support KVM for the pseries machine when using the Book3S-PR KVM variant (which runs the guest in usermode, emulating supervisor operations). This code allows gets us very close to also working with KVM Book3S-HV (using the hypervisor capabilities of recent POWER CPUs). This patch moves us another step towards Book3S-HV support by correctly handling SMT (multithreaded) POWER CPUs. There are two parts to this: * Querying KVM to check SMT capability, and if present, adjusting the cpu numbers that qemu assigns to cause KVM to assign guest threads to cores in the right way (this isn't automatic, because the POWER HV support has a limitation that different threads on a single core cannot be in different guests at the same time). * Correctly informing the guest OS of the SMT thread to core mappings via the device tree.
