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
More KVM-specific devices will come, so let's start with moving the kvmclock into a dedicated folder. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
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>

2012-01-17hw/arm_boot.c: Make SMP boards specify address to poll in bootup loopEvgeny Voevodin
The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a pen until the primary CPU releases them. Make boards specify the address to be polled to determine whether to leave the pen (it was previously hardcoded to 0x10000030, which is a Versatile Express/ Realview specific system register address).

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.
