2014-12-15cpus: make icount warp behave well with respect to stop/contPavel Dovgalyuk
This patch makes icount warp use the new QEMU_CLOCK_VIRTUAL_RT clock. This way, icount's QEMU_CLOCK_VIRTUAL will never count time during which the virtual machine is stopped. Signed-off-by: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-12-15timer: introduce new QEMU_CLOCK_VIRTUAL_RT clockPavel Dovgalyuk
This patch introduces new QEMU_CLOCK_VIRTUAL_RT clock, which should be used for icount warping. In the next patch, it will be used to avoid a huge icount warp when a virtual machine is stopped for a long time.

2014-12-15KVM_CAP_IRQFD and KVM_CAP_IRQFD_RESAMPLE checksEric Auger
Compute kvm_irqfds_allowed by checking the KVM_CAP_IRQFD extension. Remove direct settings in architecture specific files. Add a new kvm_resamplefds_allowed variable, initialized by checking the KVM_CAP_IRQFD_RESAMPLE extension. Add a corresponding kvm_resamplefds_enabled() function. A special notice for s390 where KVM_CAP_IRQFD was not immediatly advirtised when irqfd capability was introduced in the kernel. KVM_CAP_IRQ_ROUTING was advertised instead. This was fixed in "KVM: s390: announce irqfd capability", ebc3226202d5956a5963185222982d435378b899 whereas irqfd support was brought in 84223598778ba08041f4297fda485df83414d57e, "KVM: s390: irq routing for adapter interrupts". Both commits first appear in 3.15 so there should not be any kernel version impacted by this QEMU modification.

2014-11-23pc: limit DIMM address and size to page aligned valuesIgor Mammedov
When running in KVM mode, kvm_set_phys_mem() will silently fail if registered MemoryRegion address/size is not page aligned. Causing memory hotplug failure in guest. Mapping non aligned MemoryRegion in TCG mode 'works', but sane guest OS still expects page aligned memory module and fails to initialize it if it's not aligned.

2014-11-18exec: Handle multipage ranges in invalidate_and_set_dirty()Peter Maydell
The code in invalidate_and_set_dirty() needs to handle addr/length combinations which cross guest physical page boundaries. This can happen, for example, when disk I/O reads large blocks into guest RAM which previously held code that we have cached translations for. Unfortunately we were only checking the clean/dirty status of the first page in the range, and then were calling a tb_invalidate function which only handles ranges that don't cross page boundaries. Fix the function to deal with multipage ranges. The symptoms of this bug were that guest code would misbehave (eg segfault), in particular after a guest reboot but potentially any time the guest reused a page of its physical RAM for new code.

2014-11-04sysbus: Add new platform bus helper deviceAlexander Graf
We need to support spawning of sysbus devices dynamically via the command line. The easiest way to represent these dynamically spawned devices in the guest's memory and IRQ layout is by preallocating some space for dynamic sysbus devices. This is what the "platform bus" device does. It is a sysbus device that exports a configurably sized MMIO region and a configurable number of IRQ lines. When this device encounters sysbus devices that have been dynamically created and not manually wired up, it dynamically connects them to its own pool of resources. The machine model can then loop through all of these devices and create a guest configuration (device tree) to make them visible to the guest. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Expose MMIO enumeration helperAlexander Graf
Sysbus devices have a range of MMIO regions they expose. The exact number of regions is device specific and internal information to the device model. Expose whether a region exists via a public interface. That way our platform bus enumeration code can dynamically determine how many regions exist. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Expose IRQ enumeration helpersAlexander Graf
Sysbus devices can get their IRQ lines connected to other devices. It is possible to figure out which IRQ line a connection is on and whether a sysbus device even provides an IRQ connector at a specific offset. This patch exposes helpers to make this information publicly accessible. We will need it for the platform bus dynamic sysbus enumeration. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Make devices spawnable via -deviceAlexander Graf
Now that we can properly map sysbus devices that haven't been connected to something forcefully by C code, we can allow the -device command line option to spawn them. For machines that don't implement dynamic sysbus assignment in their board files we add a new bool "has_dynamic_sysbus" to the machine class. When that property is false (default), we bail out when we see dynamically spawned sysbus devices, like we did before. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-11-04sysbus: Add dynamic sysbus device searchAlexander Graf
Sysbus devices can be spawned by C code or dynamically via the command line. In the latter case, we need to be able to find the dynamically created devices to do things with them. This patch adds a search helper that makes it easy to look for dynamically spawned sysbus devices. Signed-off-by: Alexander Graf <agraf@suse.de>

2014-11-03block: Add status callback to bdrv_amend_options()Max Reitz
Depending on the changed options and the image format, bdrv_amend_options() may take a significant amount of time. In these cases, a way to be informed about the operation's status is desirable. Since the operation is rather complex and may fundamentally change the image, implementing it as AIO or a coroutine does not seem feasible. On the other hand, implementing it as a block job would be significantly more difficult than a simple callback and would not add benefits other than progress report to the amending operation, because it should not actually be run as a block job at all. A callback may not be very pretty, but it's very easy to implement and perfectly fits its purpose here.

2014-11-03qcow2: Optimize bdrv_make_empty()Max Reitz
bdrv_make_empty() is currently only called if the current image represents an external snapshot that has been committed to its base image; it is therefore unlikely to have internal snapshots. In this case, bdrv_make_empty() can be greatly sped up by emptying the L1 and refcount table (while having the dirty flag set, which only works for compat=1.1) and creating a trivial refcount structure. If there are snapshots or for compat=0.10, fall back to the simple implementation (discard all clusters).

If two of those limits are combined and the minimum is needed the minimum function should only return zero if both parameters are zero.

2014-11-03hw/core/loader: implement address translation in uimage loaderMax Filippov
Such address translation is needed when load address recorded in uImage is a virtual address. When the actual load address is requested, return untranslated address: user that needs the translated address can always apply translation function to it and those that need it untranslated don't need to do the inverse translation. Add translation function pointer and its parameter to uimage_load prototype. Update all existing users. No user-visible functional changes.

2014-11-02smbios: Encode UUID according to SMBIOS specificationEduardo Habkost
Differently from older versions, SMBIOS version 2.6 is explicit about the encoding of UUID fields: > Although RFC 4122 recommends network byte order for all fields, the PC > industry (including the ACPI, UEFI, and Microsoft specifications) has > consistently used little-endian byte encoding for the first three fields: > time_low, time_mid, time_hi_and_version. The same encoding, also known as > wire format, should also be used for the SMBIOS representation of the UUID. > > The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented > as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF. The dmidecode tool implements this and decodes the above "wire format" when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when we started building the SMBIOS entry point inside QEMU, on commit c97294ec1b9e36887e119589d456557d72ab37b5. Change smbios_build_type_1_table() to encode the UUID as specified. To make sure we won't change the guest-visible UUID when upgrading to a newer QEMU version, keep the old behavior on pc-*-2.1 and older.

2014-11-02virtio-pci: fix migration for pci bus masterMichael S. Tsirkin
Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out this code, and replace it: - Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG so just drop it for latest machine type. - For compat machine types, set PCI_COMMAND if DRIVER_OK is set. As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h to a new common header. Cc: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Michael S.
