2013-08-12virtio: clear signalled_used_valid when switching from dataplaneStefan Hajnoczi1-0/+1
When the dataplane thread stops, its vring.c implementation synchronizes vring state back to virtio.c so we can continue emulating the virtio device. This patch ensures that virtio.c's signalled_used_valid flag is reset so that we do not suppress guest notifications due to stale signalled_used values.

2013-08-08dump: populate guest_phys_blocksLaszlo Ersek1-0/+1
While the machine is paused, in guest_phys_blocks_append() we register a one-shot MemoryListener, solely for the initial collection of the valid guest-physical memory ranges that happens at listener registration time. For each range that is reported to guest_phys_blocks_region_add(), we attempt to merge the range with the preceding one. Ranges can only be joined if they are contiguous in both guest-physical address space, and contiguous in host virtual address space. The "maximal" ranges that remain in the end constitute the guest-physical memory map that the dump will be based on.

2013-07-30chardev: fix CHR_EVENT_OPENED events for mux chardevsMichael Roth1-0/+1
As of bd5c51ee6c4f1c79cae5ad2516d711a27b4ea8ec, chardevs no longer use bottom-halves to issue CHR_EVENT_OPENED events. To maintain past semantics, we instead defer the CHR_EVENT_OPENED events toward the end of chardev initialization. For muxes, this isn't good enough, since a range of FEs must be able to attach to the mux prior to any CHR_EVENT_OPENED being issued, else each FE will immediately print it's initial output (prompts, banners, etc.) just prior to us switching to the next FE as part of initialization. The is new and confusing behavior for users, as they'll see output for things like the HMP monitor, even though their the current mux focus may be a guest serial port with potentially no output. We fix this by further deferring CHR_EVENT_OPENED events for FEs associated with muxes until after machine init by flagging mux chardevs with 'explicit_be_open', which suppresses emission of CHR_EVENT_OPENED events until we explicitly set the mux as opened later. Currently, we must defer till after machine init since we potentially associate FEs with muxes as part of realize (for instance, serial_isa_realizefn).

The generic one is activated in case spice is used without qxl. The logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes unnoticed.

2013-07-29xics: rename types to be sane and follow coding styleAnthony Liguori2-8/+69
Basically, in HW the layout of the interrupt network is: - One ICP per processor thread (the "presenter"). This contains the registers to fetch a pending interrupt (ack), EOI, and control the processor priority. - One ICS per logical source of interrupts (ie, one per PCI host bridge, and a few others here or there). This contains the per-interrupt source configuration (target processor(s), priority, mask) and the per-interrupt internal state. Under PAPR, there is a single "virtual" ICS ... somewhat (it's a bit oddball what pHyp does here, arguably there are two but we can ignore that distinction). There is no register level access. A pair of firmware (RTAS) calls is used to configure each virtual interrupt. So our model here is somewhat the same. We have one ICS in the emulated XICS which arguably *is* the emulated XICS, there's no point making it a separate "device", that would just be gross, and each VCPU has an associated ICP. Yet we call the "XICS" struct icp_state and then the ICPs 'struct icp_server_state'. It's particularly confusing when all of the functions have xics_prefixes yet take *icp arguments.

At present, the savevm / migration support for the pseries machine will not work when KVM is enabled.

2013-07-29pseries: savevm support for pseries machineDavid Gibson1-3/+9
This adds the necessary pieces to implement savevm / migration for the pseries machine. The most complex part here is migrating the hash table - for the paravirtualized pseries machine the guest's hash page table is not stored within guest memory, but externally and the guest accesses it via hypercalls. This patch uses a hypervisor reserved bit of the HPTE as a dirty bit (tracking changes to the HPTE itself, not the page it references). This is used to implement a live migration style incremental save and restore of the hash table contents. Normally a hash table is 16MB but it can get bigger depending on how much RAM the guest has. Due to its nature, updates to it are random so the live migration style is used for it. In addition it adds VMStateDescription information to save and restore the (few) remaining pieces of state information needed by the pseries machine.

Bug description: QEMU currently gets all bits from GET_SUPPORTED_CPUID for CPUID leaf 0xA and passes them directly to the guest. This makes the guest ABI depend on host kernel and host CPU capabilities, and breaks live migration if we migrate between hosts with different capabilities (e.g., different number of PMU counters). Add a "pmu" property to X86CPU, and set it to true only on "-cpu host", or on pc-*-1.5 and older machine-types. For now, setting pmu=on will enable the current passthrough mode that doesn't have any ABI stability guarantees, but in the future we may implement a mode where the PMU CPUID bits are stable and configurable.

This avoids polluting the global namespace with a non-prefixed macro and makes it obvious in the call sites that we return. Semi-automatic conversion using, e.g., sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c followed by manual tweaking for sparc's GET_REGA() and Coding Style.

2013-07-26cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regsAndreas Färber1-1/+6
CPUState::gdb_num_regs replaces num_g_regs. CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS. Allows building gdb_register_coprocessor() for xtensa, too. As a side effect this should fix coprocessor register numbering for SMP.

2013-07-26Implement sync modes for drive-backup.Ian Main1-1/+3
This patch adds sync-modes to the drive-backup interface and implements the FULL, NONE and TOP modes of synchronization. FULL performs as before copying the entire contents of the drive while preserving the point-in-time using CoW. NONE only copies new writes to the target drive. TOP copies changes to the topmost drive image and preserves the point-in-time using CoW. For sync mode TOP are creating a new target image using the same backing file as the original disk image. Then any new data that has been laid on top of it since creation is copied in the main backup_run() loop. There is an extra check in the 'TOP' case so that we don't bother to copy all the data of the backing file as it already exists in the target. This is where the bdrv_co_is_allocated() is used to determine if the data exists in the topmost layer or below. Also any new data being written is intercepted via the write_notifier hook which ends up calling backup_do_cow() to copy old data out before it gets overwritten. For mode 'NONE' we create the new target image and only copy in the original data from the disk image starting from the time the call was made. This preserves the point in time data by only copying the parts that are *going to change* to the target image. This way we can reconstruct the final image by checking to see if the given block exists in the new target image first, and if it does not, you can get it from the original image. This is basically an optimization allowing you to do point-in-time snapshots with low overhead vs the 'FULL' version. Since there is no old data to copy out the loop in backup_run() for the NONE case just calls qemu_coroutine_yield() which only wakes up after an event (usually cancel in this case). The rest is handled by the before_write notifier which again calls backup_do_cow() to write out the old data so it can be preserved.
