2012-01-19kvm: Activate in-kernel irqchip supportJan Kiszka
Make the basic in-kernel irqchip support selectable via -machine ...,kernel_irqchip=on. Leave it off by default until it can fully replace user space models. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19kvm: x86: Add user space part for in-kernel IOAPICJan Kiszka
This introduces the KVM-accelerated IOAPIC model 'kvm-ioapic' and extends the IRQ routing setup by the 0->2 redirection when needed. The kvm-ioapic model has a property that allows to define its GSI base for injecting interrupts into the kernel model. This will allow to disentangle PIC and IOAPIC pins for chipsets that support more sophisticated IRQ routes than the PIIX3. So far the base is kept at 0, i.e. PIC and IOAPIC share pins 0..15.

2012-01-19kvm: x86: Add user space part for in-kernel i8259Jan Kiszka
Introduce the alternative 'kvm-i8259' device model that exploits KVM in-kernel acceleration. The PIIX3 initialization code is furthermore extended by KVM specific IRQ route setup. GSI injection differs in KVM mode from the user space model. As we can dispatch ISA-range IRQs to both IOAPIC and PIC inside the kernel, we do not need to inject them separately. This is reflected by a KVM-specific GSI handler. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19kvm: x86: Add user space part for in-kernel APICJan Kiszka
This introduces the alternative APIC device which makes use of KVM's in-kernel device model. External NMI injection via LINT1 is emulated by checking the current state of the in-kernel APIC, only injecting a NMI into the VCPU if LINT1 is unmasked and configured to DM_NMI. MSI is not yet supported, so we disable this when the in-kernel model is in use. CC: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19kvm: x86: Establish IRQ0 override controlJan Kiszka
KVM is forced to disable the IRQ0 override when we run with in-kernel irqchip but without IRQ routing support of the kernel. Set the fwcfg value correspondingly. This aligns us with qemu-kvm. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19kvm: Introduce core services for in-kernel irqchip supportJan Kiszka
Add the basic infrastructure to active in-kernel irqchip support, inject interrupts into these models, and maintain IRQ routes. Routing is optional and depends on the host arch supporting KVM_CAP_IRQ_ROUTING. When it's not available on x86, we looe the HPET as we can't route GSI0 to IOAPIC pin 2. In-kernel irqchip support will once be controlled by the machine property 'kernel_irqchip', but this is not yet wired up. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19memory: Introduce memory_region_init_reservationJan Kiszka
Introduce a memory region type that can reserve I/O space. Such regions are useful for modeling I/O that is only handled outside of QEMU, i.e. in the context of an accelerator like KVM. Any access to such a region from QEMU is a bug, but could theoretically be triggered by guest code (DMA to reserved region). So only warning about such events once, then ignore them. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19ioapic: Factor out base class for KVM reuseJan Kiszka
Split up the IOAPIC analogously to APIC and i8259. KVM will share the IOAPICCommonState, the vmstate, reset logic and certain init parts with the user space model. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19ioapic: Drop post-load irr initializationJan Kiszka
As all devices undergo a reset prior to vmloa, and the reset value of irr is 0, we do not need to do this clearing for older vmstates explicitly. Dropping this redundant code will also make KVM integration a bit simpler. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19i8259: Factor out base class for KVM reuseJan Kiszka
Analogously to the APIC, we will reuse some parts of the user space i8259 model for KVM. The base class provides a common device state, the vmstate, the property list, a reset core and some shared init bits. This also introduces a common helper to instantiate a single i8259 chip from the cascade-creating i8259_init function. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19i8259: Completely privatize PicStateJan Kiszka
Use DeviceState instead of PicState in the public i8259 API. This is cleaner and allows to reorganize the PIC data structures for KVM reuse. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19apic: Open-code timer save/restoreJan Kiszka
To enable migration between accelerated and non-accelerated APIC models, we will need to handle the timer saving and restoring specially and can no longer rely on the automatics of VMSTATE_TIMER. Specifically, accelerated model will not start any QEMUTimer. This patch therefore factors out the generic bits into apic_next_timer and use a post-load callback to implemented model-specific logic. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19apic: Factor out base class for KVM reuseJan Kiszka
The KVM in-kernel APIC model will reuse parts of the user space model while providing the same frontend view to guest and most management interfaces. Factor out an APIC base class to encapsulate those parts that will be shared by user space and KVM model. This class offers callback hooks for init, base/tpr setting, and the external NMI delivery that will be set via APICCommonInfo structure and implemented specifically in the subclasses. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19apic: Introduce apic_report_irq_deliveredJan Kiszka
The in-kernel i8259 and IOAPIC backends for KVM will need this, so encapsulate the shared bits. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19apic: Inject external NMI events via LINT1Jan Kiszka
On real hardware, NMI button events are injected via the LINT1 line of the APICs. E.g. kdump expect this wiring and gets upset if the per-APIC LINT1 mask is not respected, i.e. if NMIs are injected to VCPUs that should not receive them. Change the APIC emulation code to reflect this. Based on qemu-kvm patch by Lai Jiangshan.

2012-01-19apic: Stop timer on resetJan Kiszka
All LVTs are masked on reset, so the timer becomes ineffective. Letting it tick nevertheless is harmless, but will at least create a spurious trace event. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-01-19kvm: Move kvmclock into hw/kvm folderJan Kiszka

2012-01-19msi: Generalize msix_supported to msi_supportedJan Kiszka
Rename msix_supported to msi_supported and control MSI and MSI-X activation this way. That was likely to original intention for this flag, but MSI support came after MSI-X. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a pen until the primary CPU releases them.

2012-01-13virtio-blk: refuse SG_IO requests with scsi=offPaolo Bonzini
QEMU does have a "scsi" option (to be used like -device virtio-blk-pci,drive=foo,scsi=off). However, it only masks the feature bit, and does not reject the command if a malicious guest disregards the feature bits and issues a request. Without this patch, using scsi=off does not protect you from CVE-2011-4127.
