2016-03-11nvdimm acpi: initialize the resource used by NVDIMM ACPIXiao Guangrong
32 bits IO port starting from 0x0a18 in guest is reserved for NVDIMM ACPI emulation. The table, NVDIMM_DSM_MEM_FILE, will be patched into NVDIMM ACPI binary code OSPM uses this port to tell QEMU the final address of the DSM memory and notify QEMU to emulate the DSM method Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

2016-01-21target-i386: Add support to migrate vcpu's TSC rateHaozhong Zhang
This patch enables migrating vcpu's TSC rate. If KVM on the destination machine supports TSC scaling, guest programs will observe a consistent TSC rate across the migration. If TSC scaling is not supported on the destination machine, the migration will not be aborted and QEMU on the destination will not set vcpu's TSC rate to the migrated value. If vcpu's TSC rate specified by CPU option 'tsc-freq' on the destination machine is inconsistent with the migrated TSC rate, the migration will be aborted. For backwards compatibility, the migration of vcpu's TSC rate is disabled on pc-*-2.5 and older machine types.

2016-01-13isa: Clean up error handling around isa_bus_new()Markus Armbruster
We can have at most one ISA bus. If you try to create another one, isa_bus_new() complains to stderr and returns null. isa_bus_new() is called in two contexts, machine's init() and device's realize() methods. Since complaining to stderr is not proper in the latter context, convert isa_bus_new() to Error. Machine's init(): * mips_jazz_init(), called from the init() methods of machines "magnum" and "pica" * mips_r4k_init(), the init() method of machine "mips" * pc_init1() called from the init() methods of non-q35 PC machines * typhoon_init(), called from clipper_init(), the init() method of machine "clipper" These callers always create the first ISA bus, hence isa_bus_new() can't fail. Simply pass &error_abort. Device's realize(): * i82378_realize(), of PCI device "i82378" * ich9_lpc_realize(), of PCI device "ICH9-LPC" * pci_ebus_realize(), of PCI device "ebus" * piix3_realize(), of PCI device "pci-piix3", abstract parent of "PIIX3" and "PIIX3-xen" * piix4_realize(), of PCI device "PIIX4" * vt82c686b_realize(), of PCI device "VT82C686B" Propagate the error. Note that these devices are typically created only by machine init() methods with qdev_init_nofail() or similar. If we screwed up and created an ISA bus before that call, we now give up right away. Before, we'd hobble on, and typically die in isa_bus_irqs(). Similar if someone finds a way to hot-plug one of these critters. Cc: Richard Henderson <rth@twiddle.net> Cc: "Michael S.

2015-12-17kvm: x86: add support for KVM_CAP_SPLIT_IRQCHIPPaolo Bonzini
This patch adds support for split IRQ chip mode. When KVM_CAP_SPLIT_IRQCHIP is enabled: 1.) The PIC, PIT, and IOAPIC are implemented in userspace while the LAPIC is implemented by KVM. 2.) The software IOAPIC delivers interrupts to the KVM LAPIC via kvm_set_irq. Interrupt delivery is configured via the MSI routing table, for which routes are reserved in target-i386/kvm.c then configured in hw/intc/ioapic.c 3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI, which is handled in target-i386/kvm.c and relayed to the software IOAPIC via ioapic_eoi_broadcast.

Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated.

2015-11-04pc: Set hw_version on all machine classesEduardo Habkost
In 2012, QEMU had a bug where it exposed QEMU version information to the guest, meaning a QEMU upgrade would expose different hardware to the guest OS even if the same machine-type is being used. The bug was fixed by commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4, on all machines up to pc-1.0. But we kept introducing the same bug on all newer machines since then. That means we are breaking guest ABI every time QEMU was upgraded. Fix this by setting the hw_version on all PC machines, making sure the hardware won't change when upgrading QEMU. Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU 1.1.0, it started following the "x.y.0" pattern. We have to follow it, to make sure we use the right QEMU_VERSION string from each QEMU release. The 2.5 machine classes could have hw_version unset, because the default value for qemu_get_version() is QEMU_VERSION. But I decided to set it explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0" after we release 2.5.0 and create a 2.6 machine class.

2015-09-10igd gfx passthrough: create a isa bridgeTiejun Chen
Currently IGD drivers always need to access PCH by 1f.0. But we don't want to poke that directly to get ID, and although in real world different GPU should have different PCH. But actually the different PCH DIDs likely map to different PCH SKUs. We do the same thing for the GPU. For PCH, the different SKUs are going to be all the same silicon design and implementation, just different features turn on and off with fuses. The SW interfaces should be consistent across all SKUs in a given family (eg LPT). But just same features may not be supported. Most of these different PCH features probably don't matter to the Gfx driver, but obviously any difference in display port connections will so it should be fine with any PCH in case of passthrough. So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell) scenarios, 0x9cc3 for BDW(Broadwell).

2015-08-13smbios: move smbios code into a common folderWei Huang
To share smbios among different architectures, this patch moves SMBIOS code (smbios.c and smbios.h) from x86 specific folders into new hw/smbios directories. As a result, CONFIG_SMBIOS=y is defined in x86 default config files.

2015-08-13pc: Eliminate pc_default_machine_options()Eduardo Habkost
The only PC machines that didn't call pc_default_machine_options() were isaps and xenfv. Both were already overwriting max_cpus, and only isapc was not overwriting hot_add_cpu. After making isapc set hot_add_cpu to NULL, we can move the pc_default_machine_options() code the PC common class_init. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.
