[PATCH RFC v3 0/9] KVM: allow dynamic kvm->vcpus array
The only common part with v2 is [v3 5/9]. The crucial part of this series is adding a separate mechanism for kvm_for_each_vcpu() [v3 8/9] and with that change, I think that the dynamic array [v3 9/9] would be nicer if protected by RCU, like in v2: The protection can be nicely hidden in kvm_get_vcpu(). I just had the split done before implementing [v3 8/9] and presented it for consideration. Smoke tested on x86 only. Radim Krčmář (9): KVM: s390: optimize detection of started vcpus KVM: arm/arm64: fix vcpu self-detection in vgic_v3_dispatch_sgi() KVM: remember position in kvm->vcpus array KVM: arm/arm64: use locking helpers in kvm_vgic_create() KVM: remove unused __KVM_HAVE_ARCH_VM_ALLOC KVM: rework kvm_vcpu_on_spin loop KVM: add kvm_free_vcpus and kvm_arch_free_vcpus KVM: implement kvm_for_each_vcpu with a list KVM: split kvm->vcpus into chunks arch/mips/kvm/mips.c| 19 ++ arch/powerpc/kvm/book3s_32_mmu.c| 3 +- arch/powerpc/kvm/book3s_64_mmu.c| 3 +- arch/powerpc/kvm/book3s_hv.c| 7 +- arch/powerpc/kvm/book3s_pr.c| 5 +- arch/powerpc/kvm/book3s_xics.c | 2 +- arch/powerpc/kvm/book3s_xics.h | 3 +- arch/powerpc/kvm/book3s_xive.c | 18 +++--- arch/powerpc/kvm/book3s_xive.h | 3 +- arch/powerpc/kvm/e500_emulate.c | 3 +- arch/powerpc/kvm/powerpc.c | 16 ++--- arch/s390/include/asm/kvm_host.h| 1 + arch/s390/kvm/interrupt.c | 3 +- arch/s390/kvm/kvm-s390.c| 77 -- arch/s390/kvm/kvm-s390.h| 6 +- arch/s390/kvm/sigp.c| 3 +- arch/x86/kvm/hyperv.c | 3 +- arch/x86/kvm/i8254.c| 3 +- arch/x86/kvm/i8259.c| 7 +- arch/x86/kvm/ioapic.c | 3 +- arch/x86/kvm/irq_comm.c | 10 +-- arch/x86/kvm/lapic.c| 5 +- arch/x86/kvm/svm.c | 3 +- arch/x86/kvm/vmx.c | 5 +- arch/x86/kvm/x86.c | 34 -- include/linux/kvm_host.h| 81 --- virt/kvm/arm/arch_timer.c | 10 ++- virt/kvm/arm/arm.c | 25 virt/kvm/arm/pmu.c | 3 +- virt/kvm/arm/psci.c | 7 +- virt/kvm/arm/vgic/vgic-init.c | 31 - virt/kvm/arm/vgic/vgic-kvm-device.c | 30 + virt/kvm/arm/vgic/vgic-mmio-v2.c| 5 +- virt/kvm/arm/vgic/vgic-mmio-v3.c| 22 --- virt/kvm/arm/vgic/vgic.c| 3 +- virt/kvm/kvm_main.c | 124 +++- 36 files changed, 278 insertions(+), 308 deletions(-) -- 2.13.3
