2013-04-08hw: move hw/kvm/ to hw/i386/kvmPaolo Bonzini1-209/+0
Peter requested the KVM GIC to be in hw/intc. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-01-10Make all static TypeInfos constAndreas Färber1-1/+1
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-12-17pci: update all users to look in pci/Michael S. Tsirkin1-1/+1
update all users so we can remove the makefile hack. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-10-31cpus: Pass CPUState to run_on_cpu()Andreas Färber1-1/+1
CPUArchState is no longer needed. Move the declaration to include/qemu/cpu.h and add documentation. Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-10-30apic: Store X86CPU in APICCommonStateAndreas Färber1-4/+4
Prepares for using a link<> property to connect APIC with CPU and for changing the CPU APIs to CPUState. Resolve Coding Style warnings by moving the closing parenthesis of foreach_apic() macro to next line. Signed-off-by: Andreas Färber <afaerber@suse.de> Reviewed-by: Igor Mammedov <imammedo@redhat.com>
2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-2/+2
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-06-11kvm/apic: correct short memsetJim Meyering1-1/+1
kvm_put_apic_state's attempt to clear *kapic before setting its bits cleared sizeof(void*) bytes (no more than 8) rather than the intended 1024 (KVM_APIC_REG_SIZE) bytes. Spotted by coverity. Signed-off-by: Jim Meyering <meyering@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

Catch writes to the MSI MMIO region in the KVM APIC and forward them to the kernel. Provide the kernel support GSI routing, this allows to enable MSI support also for in-kernel irqchip mode. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2012-02-18kvmvapic: Introduce TPR access optimization for Windows guestsJan Kiszka1-0/+32
This enables acceleration for MMIO-based TPR registers accesses of 32-bit Windows guest systems. It is mostly useful with KVM enabled, either on older Intel CPUs (without flexpriority feature, can also be manually disabled for testing) or any current AMD processor. The approach introduced here is derived from the original version of qemu-kvm. It was refactored, documented, and extended by support for user space APIC emulation, both with and without KVM acceleration. The VMState format was kept compatible, so was the ABI to the option ROM that implements the guest-side para-virtualized driver service. This enables seamless migration from qemu-kvm to upstream or, one day, between KVM and TCG mode. The basic concept goes like this: - VAPIC PV interface consisting of I/O port 0x7e and (for KVM in-kernel irqchip) a vmcall hypercall is registered - VAPIC option ROM is loaded into guest - option ROM activates TPR MMIO access reporting via port 0x7e - TPR accesses are trapped and patched in the guest to call into option ROM instead, VAPIC support is enabled - option ROM TPR helpers track state in memory and invoke hypercall to poll for pending IRQs if required Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-02-15qom: Unify type registrationAndreas Färber1-2/+2
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 Liguori1-2/+3
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 Liguori1-6/+13
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>
2012-01-19kvm: 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>
