Hello! How are things going? There was lots of activity, discussions, and then - silence... Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia > -----Original Message----- > From: kvm-owner@xxxxxxxxxxxxxxx [mailto:kvm-owner@xxxxxxxxxxxxxxx] On Behalf Of Pavel Fedin > Sent: Monday, October 12, 2015 11:30 AM > To: kvmarm@xxxxxxxxxxxxxxxxxxxxx; kvm@xxxxxxxxxxxxxxx > Cc: Christoffer Dall; Marc Zyngier; Andre Przywara > Subject: [PATCH v5 0/7] KVM: arm64: Implement API for vGICv3 live migration > > This patchset adds necessary userspace API in order to support vGICv3 live > migration. GICv3 registers are accessed using device attribute ioctls, > similar to GICv2. > > Whoever wants to test it, please note that this version is not > binary-compatible with previous one, the API has been seriously changed. > qemu patchess will be posted in some time. > > v4 => v5: > - Adapted to new API by Peter Maydell, Marc Zyngier and Christoffer Dall. > Acked-by's on the documentation were dropped, just in case, because i > slightly adjusted it. Additionally, i merged all doc updates into one > patch. > > v3 => v4: > - Split pure refactoring from anything else > - Documentation brought up to date > - Cleaned up 'mmio' structure usage in vgic_attr_regs_access(), > use call_range_handler() for 64-bit access handling > - Rebased on new linux-next > > v2 => v3: > - KVM_DEV_ARM_VGIC_CPUID_MASK enlarged to 20 bits, allowing more than 256 > CPUs. > - Bug fix: Correctly set mmio->private, necessary for redistributor access. > - Added accessors for ICC_AP0R and ICC_AP1R registers > - Rebased on new linux-next > > v1 => v2: > - Do not use generic register get/set API for CPU interface, use only > device attributes. > - Introduce size specifier for distributor and redistributor register > accesses, do not assume size any more. > - Lots of refactor and reusable code extraction. > - Added forgotten documentation > > Christoffer Dall (1): > KVM: arm/arm64: Update API documentation > > Pavel Fedin (6): > KVM: arm/arm64: Move endianess conversion out of > vgic_attr_regs_access() > KVM: arm/arm64: Refactor vGIC attributes handling code > KVM: arm64: Implement vGICv3 distributor and redistributor access from > userspace > KVM: arm64: Refactor system register handlers > KVM: arm64: Introduce find_reg_by_id() > KVM: arm64: Implement vGICv3 CPU interface access > > Documentation/virtual/kvm/devices/arm-vgic-v3.txt | 117 ++++++++ > Documentation/virtual/kvm/devices/arm-vgic.txt | 41 +-- > arch/arm64/include/uapi/asm/kvm.h | 17 +- > arch/arm64/kvm/sys_regs.c | 83 +++--- > arch/arm64/kvm/sys_regs.h | 8 +- > arch/arm64/kvm/sys_regs_generic_v8.c | 2 +- > include/linux/irqchip/arm-gic-v3.h | 19 +- > virt/kvm/arm/vgic-v2-emul.c | 124 ++------ > virt/kvm/arm/vgic-v3-emul.c | 343 +++++++++++++++++++++- > virt/kvm/arm/vgic.c | 57 ++++ > virt/kvm/arm/vgic.h | 3 + > 11 files changed, 630 insertions(+), 184 deletions(-) > create mode 100644 Documentation/virtual/kvm/devices/arm-vgic-v3.txt > > -- > 2.4.4 > > -- > To unsubscribe from this list: send the line "unsubscribe kvm" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
