2016-02-26target-mips: implement R6 multi-threadingYongbok Kim7-1/+151
MIPS Release 6 provides multi-threading features which replace pre-R6 MT Module. CP0.Config3.MT is always 0 in R6, instead there is new CP0.Config5.VP (Virtual Processor) bit which indicates presence of multi-threading support which includes CP0.GlobalNumber register and DVP/EVP instructions.

2016-02-26mips/kvm: Support MSA in MIPS KVM guestsJames Hogan1-20/+109
Support the new KVM_CAP_MIPS_MSA capability, which allows MIPS SIMD Architecture (MSA) to be exposed to the KVM guest. The capability is enabled if the guest core has MSA according to its Config3 register. Various config bits are now writeable so that KVM is aware of the configuration (Config3.MSAP) and so that QEMU can save/restore the guest modifiable bits (Config5.MSAEn). The MSACSR/MSAIR registers and the MSA vector registers are now saved/restored. Since the FP registers are a subset of the vector registers, they are omitted if the guest has MSA.

2016-02-26mips/kvm: Support FPU in MIPS KVM guestsJames Hogan1-4/+117
Support the new KVM_CAP_MIPS_FPU capability, which allows the host's FPU to be exposed to the KVM guest. The capability is enabled if the guest core has an FPU according to its Config1 register. Various config bits are now writeable so that KVM is aware of the configuration (Config1.FP) and so that QEMU can save/restore the guest modifiable bits (Config5.FRE, Config5.UFR, Config5.UFE). The FCSR/FIR registers and the floating point registers are now saved/restored (depending on the FR mode bit).

2016-02-26mips/kvm: Support signed 64-bit KVM registersJames Hogan1-9/+31
Rename kvm_mips_{get,put}_one_reg64() to kvm_mips_{get,put}_one_ureg64() since they take an int64_t pointer, and add separate signed 64-bit accessors.

2016-02-26mips/kvm: Implement Config CP0 registersJames Hogan1-0/+106
Implement saving and restoring to KVM state of the Config CP0 registers (namely Config, Config1, Config2, Config3, Config4, and Config5). These control the features available to a guest, and a few of the fields will soon be writeable by a guest so QEMU needs to know about them so as not to clobber them on migration/savevm.

2016-02-25qga: fix w32 breakage due to missing osdep.h includesMichael Roth5-9/+8
requester.h relied on qemu/compiler.h definitions to handle GCC_FMT_ATTR() stub, but this include was removed as part of scripted clean-ups via 30456d5: all: Clean up includes under the assumption that all C files would have included it via qemu/osdep.h at that point. requester.cpp was likely missed due to C++ files requiring manual/special handling as well as VSS build options needing to be enabled to trigger build failures. Fix this by including qemu/osdep.h. That in turn pulls in a macro from qapi/error.h that conflicts with a struct field name in requester.h, so fix that as well by renaming the field. While we're at it, fix up provider.cpp/install.cpp to include osdep.h as well.

2016-02-25qga: Support enum names in guest-file-seekEric Blake6-40/+70
Magic constants are a pain to use, especially when we run the risk that our choice of '1' for QGA_SEEK_CUR might differ from the host or guest's choice of SEEK_CUR. Better is to use an enum value, via a qapi alternate type for back-compatibility. With this, {"command":"guest-file-seek", "arguments":{"handle":1, "offset":0, "whence":"cur"}} becomes a synonym for the older {"command":"guest-file-seek", "arguments":{"handle":1, "offset":0, "whence":1}} Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

Each RAM memory region has a unique corresponding RAMBlock. In the current realization, the memory region only stored the ram_addr which means the offset of RAM address space, We need to qurey the global ram.list to find the ram block by ram_addr if we want to get the ram block, which is very expensive. Now, we store the RAMBlock pointer into memory region structure. So, if we know the mr, we can easily get the RAMBlock.

Migration with q35 was not possible before commit 04329029a8c539eb5f75dcb6d8b016f0c53a031a, because q35 unconditionally creates an ich9-ahci device, that was marked as unmigratable.

2016-02-25virtio-blk: fix "disabled data plane" modePaolo Bonzini3-13/+11
In disabled mode, virtio-blk dataplane seems to be enabled, but flow actually goes through the normal virtio path. This patch simplifies a bit the handling of disabled mode. In disabled mode, virtio_blk_handle_output might be called even if s->dataplane is not NULL. This is a bit tricky, because the current check for s->dataplane will always trigger, causing a continuous stream of calls to virtio_blk_data_plane_start. Unfortunately, these calls will not do anything. To fix this, set the "started" flag even in disabled mode, and skip virtio_blk_data_plane_start if the started flag is true. The resulting changes also prepare the code for the next patch, were virtio-blk dataplane will reuse the same virtio_blk_handle_output function as "regular" virtio-blk. Because struct VirtIOBlockDataPlane is opaque in virtio-blk.c, we have to move s->dataplane->started inside struct VirtIOBlock.

2016-02-25virtio: export vring_notify as virtio_should_notifyPaolo Bonzini2-2/+3
Virtio dataplane needs to trigger the irq manually through the guest notifier. Export virtio_should_notify so that it can be used around event_notifier_set.

2016-02-25block-migration: acquire AioContext as necessaryPaolo Bonzini1-13/+52
This is needed because dataplane will run during block migration as well. The block device migration code is quite liberal in taking the iothread mutex. For simplicity, keep it the same way, even though one could actually choose between the BQL (for regular BlockDriverStates) and the AioContext (for dataplane BlockDriverStates). When the block layer is made fully thread safe, aio_context_acquire shall go away altogether. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael S.
