2011-05-03qemu-kvm: Do not advertise MSI caps on lacking KVM supportJan Kiszka1-4/+0
As suggested by Michael Tsirkin: Move the check for GSI routing from kvm_msi_message_add to the MSI/MSI-X initalization. If it fails (and KVM is in in-kernel irqchip mode), do not advertise MSI at all. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-04-27qemu-kvm: Move entry comparison into kvm_msi_update_messageJan Kiszka1-1/+13
Checking the the update chances the message content is a common task for both MSI types. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-04-27qemu-kvm: Move gsi bits from kvm_msix_vector_add to kvm_msi_add_messageJan Kiszka1-0/+11
Testing support and allocating a GSI for an MSI message is required both for MSI and MSI-X. At this chance, drop the aging version warning. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-04-27qemu-kvm: Refactor MSI core API of KVMJan Kiszka1-19/+13
Remove MSI-X from function names - the interface is valid for MSI as well - and use KVMMsiMessage as parameter. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-04-20qemu-kvm: Unbreak guest debuggingJan Kiszka1-30/+6
Align handling of guest debug exits to upstream by moving it completely to the arch section. This patch accounts for changed return codes in the exit handling code. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-04-20qemu-kvm: Process async MCE events in main loopJan Kiszka1-3/+6
This aligns qemu-kvm with upstream commit ab443475c9. Namely, we were missing a call to an equivalent of kvm_arch_process_async_events from the main loop. This adds a stripped down version of upstream's process_async_events until we switch over. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-04-20qemu-kvm: Synchronize states before resetJan Kiszka1-0/+2

2010-10-14Avoid use of kvm_irq_routing_entry in hw/msix.cAvi Kivity1-0/+44
kvm_irq_routing_entry cannot be used when CONFIG_KVM is disabled; add a new interface to the kvm support code that uses scalars instead. Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-10-14kvm: drop kvm_context parameter from msix-related kvm functionsAvi Kivity1-14/+19
The kvm_context parameter serves no useful purpose since it's a global (and all callers reference that global); on the other hand it prevents the build when kvm is not configured in since the kvm_context symbol is not defined. Remove the parameter and replace it by the global kvm_context in callees. Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-10-08Fix SRAO/SRAR MCE injecting on guest without MCG_SER_PHuang Ying1-3/+3
On real machine, if MCG_SER_P in MSR_MCG_CAP is not set, SRAO/SRAR MCE should not be raised by hardware. This patch makes QEMU-KVM to follow the same rule.

2010-09-20Add RAM -> physical addr mapping in MCE simulationHuang Ying1-3/+10
In QEMU-KVM, physical address != RAM address. While MCE simulation needs physical address instead of RAM address. So kvm_physical_memory_addr_from_ram() is implemented to do the conversion, and it is invoked before being filled in the IA32_MCi_ADDR MSR.

2010-06-23do not enter vcpu again if it was stopped during IOGleb Natapov1-0/+4
To prevent reentering vcpu after IO completion it is not enough to set env->stopped since it is checked only in main loop but control will not get there until next non-IO exit since kvm_run() will reenter vcpu to complete IO instruction. Solve this by sending self-signal to request exit after IO instruction completion. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

This patch address bug report in https://bugs.launchpad.net/qemu/+bug/530077. Failed vmentries were handled with handle_unhandled() which prints a rather unfriendly message to the user.

2010-04-28Ignore SRAO MCE if another MCE is being processedHuang Ying1-0/+28
In common cases, guest SRAO MCE will cause corresponding poisoned page be un-mapped in host and SIGBUS be sent to QEMU-KVM, then QEMU-KVM will relay the MCE to guest OS. But it is possible that the poisoned page is accessed in guest after un-mapped in host and before MCE is relayed to guest OS. So that, the SRAR SIGBUS is sent to QEMU-KVM before the SRAO SIGBUS, and if QEMU-KVM relays them to guest OS one by one, guest system may reset, because the SRAO MCE may be triggered while the SRAR MCE is being processed. In fact, the SRAO MCE can be ignored in this situation, so that the guest system is given opportunity to survive.
