2012-02-17i8259: Do not clear level-triggered lines in IRR on initJan Kiszka1-1/+1
When an input line is handled as level-triggered, it will immediately raise an IRQ on the output of a PIC again that goes through an init reset. So only clear the edge-triggered inputs from IRR in that scenario. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-15qom: Unify type registrationAndreas Färber4-8/+8
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori4-20/+29
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27sysbus: apic: ioapic: convert to QEMU Object ModelAnthony Liguori3-20/+41
This converts three devices because apic and ioapic are subclasses of sysbus. Converting subclasses independently of their base class is prohibitively hard. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27isa: pic: convert to QEMU Object ModelAnthony Liguori1-6/+13
This converts two devices at once because PIC subclasses ISA and converting subclasses independently is extremely hard. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-19kvm: x86: Add user space part for in-kernel IOAPICJan Kiszka1-0/+114
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 Kiszka1-0/+128
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 Kiszka1-0/+138
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>
