2010-03-01KVM: powerpc: Change maintainerAlexander Graf
Progress on KVM for Embedded PowerPC has stalled, but for Book3S there's quite a lot of work to do and going on. So in agreement with Hollis and Avi, we should switch maintainers for PowerPC. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Hollis Blanchard <hollis@penguinppc.org> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: powerpc: Remove AGGRESSIVE_DECAlexander Graf
Because we now emulate the DEC interrupt according to real life behavior, there's no need to keep the AGGRESSIVE_DEC hack around. Let's just remove it.

2010-03-01KVM: powerpc: Improve DEC handlingAlexander Graf
We treated the DEC interrupt like an edge based one. This is not true for Book3s. The DEC keeps firing until mtdec is issued again and thus clears the interrupt line. So let's implement this logic in KVM too. This patch moves the line clearing from the firing of the interrupt to the mtdec emulation. This makes PPC64 guests work without AGGRESSIVE_DEC defined.

2010-03-01KVM: powerpc: Move vector to irqprio resolving to separate functionAlexander Graf
We're using a switch table to find the irqprio that belongs to a specific interrupt vector. This table is part of the interrupt inject logic. Since we'll add a new function to stop interrupts, let's move this table out of the injection logic into a separate function.

2010-03-01KVM: Simplify coalesced mmio initializationAvi Kivity

2010-03-01KVM: SVM: Adjust tsc_offset only if tsc_unstableJoerg Roedel
The tsc_offset adjustment in svm_vcpu_load is executed unconditionally even if Linux considers the host tsc as stable. This causes a Linux guest detecting an unstable tsc in any case. This patch removes the tsc_offset adjustment if the host tsc is stable. The guest will now get the benefit of a stable tsc too.

2010-03-01KVM: VMX: Add instruction rdtscp support for guestSheng Yang
Before enabling, execution of "rdtscp" in guest would result in #UD. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: Add cpuid_update() callback to kvm_x86_opsSheng Yang
Sometime, we need to adjust some state in order to reflect guest CPUID setting, e.g. if we don't expose rdtscp to guest, we won't want to enable it on hardware. cpuid_update() is introduced for this purpose. Also export kvm_find_cpuid_entry() for later use. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01x86: Raise vsyscall priority on hotplug notifier chainSheng Yang
KVM need vsyscall_init() to initialize MSR_TSC_AUX before it read the value. Per Avi's suggestion, this patch raised vsyscall priority on hotplug notifier chain, to 30.

2010-03-01KVM: Extended shared_msr_global to per CPUSheng Yang
shared_msr_global saved host value of relevant MSRs, but it have an assumption that all MSRs it tracked shared the value across the different CPUs. It's not true with some MSRs, e.g. MSR_TSC_AUX. Extend it to per CPU to provide the support of MSR_TSC_AUX, and more alike MSRs. Notice now the shared_msr_global still have one assumption: it can only deal with the MSRs that won't change in host after KVM module loaded.

2010-03-01KVM: VMX: Fold ept_update_paging_mode_cr4() into its callerAvi Kivity
ept_update_paging_mode_cr4() accesses vcpu->arch.cr4 directly, which usually needs to be accessed via kvm_read_cr4(). In this case, we can't, since cr4 is in the process of being updated. Instead of adding inane comments, fold the function into its caller (vmx_set_cr4), so it can use the not-yet-committed cr4 directly. Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: VMX: When using ept, allow the guest to own cr4.pgeAvi Kivity
We make no use of cr4.pge if ept is enabled, but the guest does (to flush global mappings, as with vmap()), so give the guest ownership of this bit. Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: VMX: Make guest cr4 mask more conservativeAvi Kivity
Instead of specifying the bits which we want to trap on, specify the bits which we allow the guest to change transparently. This is safer wrt future changes to cr4. Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: Add accessor for reading cr4 (or some bits of cr4)Avi Kivity
Some bits of cr4 can be owned by the guest on vmx, so when we read them, we copy them to the vcpu structure. In preparation for making the set of guest-owned bits dynamic, use helpers to access these bits so we don't need to know where the bit resides. No changes to svm since all bits are host-owned there. Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: VMX: Move some cr[04] related constants to vmx.cAvi Kivity
They have no place in common code. Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: VMX: Trap and invalid MWAIT/MONITOR instructionSheng Yang
We don't support these instructions, but guest can execute them even if the feature('monitor') haven't been exposed in CPUID. So we would trap and inject a #UD if guest try this way. Cc: stable@kernel.org Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: MMU: Report spte not found in rmap before BUG()Avi Kivity
