This series contains the fourth version of KVM for arm64. It depends on the following branche: - git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm/fixes a small number of fixes and other files being moved around The code is unsurprisingly extremely similar to the KVM/arm code, and a lot of it is actually shared with the 32bit version. Most of the duplicated code has now been eliminated by moving it to a common, architecture agnostic location. In terms of features: - Support for 4k and 64k pages - Support for 32bit and 64bit guests - PSCI support for SMP booting Testing has been done on both AEMv8 and Foundation models, with various 32 and 64bit guests running a variety of distributions (OE, Ubuntu and openSUSE for 64bit, Debian and Ubuntu on 32bit). The patches are also available on the following branch: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm64/kvm As we do not have a 64bit QEMU port, it has been tested using kvmtools. Note that some of the changes have broken the userspace ABI in v2 and v3, and you must update and rebuild your kvmtools (the previous versions won't work anymore): git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm64/kvmtool KVM maintainers: this series introduces a new capability (KVM_CAP_ARM_EL1_32BIT, 93) and a new ONE_REG architecture (KVM_REG_ARM64, 0x6000000000000000ULL). Can we make sure these won't clash with any other upcoming patches? If they already do, can you allocate safe and reserved numbers? >From v3: - Now relies on vgic/timer being moved to virt/kvm/arm - Also relies on quite a few 32bit changes, and mimics some other 32bit fixes that have been merged already - Fixed a number of MMU setup issues (Will, Catalin, Pranavkumar) - Fixed a number of issues in the sys_regs interface, updated documentation (Christoffer) - Add a short EL2 memory-map section to memory.txt >From v2: - Dropped the idmap code and use the new KVM/ARM boot protocol - New KVM_CAP_ARM_EL1_32BIT capability to let userspace detect if EL1 is 32bit capable - Fixed a bug in arch/arm/entry.S, where EL0/EL1 breakpoint handling was mixed up (spotted by Catalin Marinas) - Some sparse fixes (courtesy of Geoff Levand) - Dropped the "shared" attribute from device mappings (spotted by Catalin) - Add API documentation - Add MAINTAINERS entry >From v1: - Rework of the world-switch to use common structure between host and guests (suggested by Christopher Covington) - Some additional constants to make the EL1 fault injection clearer (suggested by Christopher Covington) - Use of __u64 instead of "unsigned long" in the userspace API (suggested by Michael S. Tsirkin) - Move the FP/SIMD registers into the "core" registers, dropping the specific accessors. - Generic MPIDR implementation (suggested by Christopher Covington) - Cleaner handling of the various host implementations Marc Zyngier (32): arm64: KVM: define HYP and Stage-2 translation page flags arm64: KVM: HYP mode idmap support arm64: KVM: EL2 register definitions arm64: KVM: system register definitions for 64bit guests arm64: KVM: Basic ESR_EL2 helpers and vcpu register access arm64: KVM: fault injection into a guest arm64: KVM: architecture specific MMU backend arm64: KVM: user space interface arm64: KVM: system register handling arm64: KVM: CPU specific system registers handling arm64: KVM: virtual CPU reset arm64: KVM: kvm_arch and kvm_vcpu_arch definitions arm64: KVM: MMIO access backend arm64: KVM: guest one-reg interface arm64: KVM: hypervisor initialization code arm64: KVM: HYP mode world switch implementation arm64: KVM: Exit handling arm64: KVM: Plug the VGIC arm64: KVM: Plug the arch timer arm64: KVM: PSCI implementation arm64: KVM: Build system integration arm64: KVM: define 32bit specific registers arm64: KVM: 32bit GP register access arm64: KVM: 32bit conditional execution emulation arm64: KVM: 32bit handling of coprocessor traps arm64: KVM: CPU specific 32bit coprocessor access arm64: KVM: 32bit specific register world switch arm64: KVM: 32bit guest fault injection arm64: KVM: enable initialization of a 32bit vcpu arm64: KVM: userspace API documentation arm64: KVM: MAINTAINERS update arm64: KVM: document kernel object mappings in HYP Documentation/arm64/memory.txt | 7 + Documentation/virtual/kvm/api.txt | 58 +- MAINTAINERS | 9 + arch/arm64/Kconfig | 2 + arch/arm64/Makefile | 2 +- arch/arm64/include/asm/kvm_arm.h | 245 ++++++++ arch/arm64/include/asm/kvm_asm.h | 104 ++++ arch/arm64/include/asm/kvm_coproc.h | 56 ++ arch/arm64/include/asm/kvm_emulate.h | 180 ++++++ arch/arm64/include/asm/kvm_host.h | 202 ++++++ arch/arm64/include/asm/kvm_mmio.h | 59 ++ arch/arm64/include/asm/kvm_mmu.h | 135 ++++ arch/arm64/include/asm/kvm_psci.h | 23 + arch/arm64/include/asm/memory.h | 5 + arch/arm64/include/asm/pgtable-hwdef.h | 19 + arch/arm64/include/asm/pgtable.h | 11 + arch/arm64/include/uapi/asm/kvm.h | 168 +++++ arch/arm64/kernel/asm-offsets.c | 34 ++ arch/arm64/kernel/vmlinux.lds.S | 20 + arch/arm64/kvm/Kconfig | 59 ++ arch/arm64/kvm/Makefile | 23 + arch/arm64/kvm/emulate.c | 158 +++++ arch/arm64/kvm/guest.c | 259 ++++++++ arch/arm64/kvm/handle_exit.c | 124 ++++ arch/arm64/kvm/hyp-init.S | 112 ++++ arch/arm64/kvm/hyp.S | 817 +++++++++++++++++++++++++ arch/arm64/kvm/inject_fault.c | 203 ++++++ arch/arm64/kvm/regmap.c | 168 +++++ arch/arm64/kvm/reset.c | 100 +++ arch/arm64/kvm/sys_regs.c | 1050 ++++++++++++++++++++++++++++++++ arch/arm64/kvm/sys_regs.h | 138 +++++ arch/arm64/kvm/sys_regs_generic_v8.c | 95 +++ include/uapi/linux/kvm.h | 2 + virt/kvm/arm/arch_timer.c | 1 + 34 files changed, 4628 insertions(+), 20 deletions(-) create mode 100644 arch/arm64/include/asm/kvm_arm.h create mode 100644 arch/arm64/include/asm/kvm_asm.h create mode 100644 arch/arm64/include/asm/kvm_coproc.h create mode 100644 arch/arm64/include/asm/kvm_emulate.h create mode 100644 arch/arm64/include/asm/kvm_host.h create mode 100644 arch/arm64/include/asm/kvm_mmio.h create mode 100644 arch/arm64/include/asm/kvm_mmu.h create mode 100644 arch/arm64/include/asm/kvm_psci.h create mode 100644 arch/arm64/include/uapi/asm/kvm.h create mode 100644 arch/arm64/kvm/Kconfig create mode 100644 arch/arm64/kvm/Makefile create mode 100644 arch/arm64/kvm/emulate.c create mode 100644 arch/arm64/kvm/guest.c create mode 100644 arch/arm64/kvm/handle_exit.c create mode 100644 arch/arm64/kvm/hyp-init.S create mode 100644 arch/arm64/kvm/hyp.S create mode 100644 arch/arm64/kvm/inject_fault.c create mode 100644 arch/arm64/kvm/regmap.c create mode 100644 arch/arm64/kvm/reset.c create mode 100644 arch/arm64/kvm/sys_regs.c create mode 100644 arch/arm64/kvm/sys_regs.h create mode 100644 arch/arm64/kvm/sys_regs_generic_v8.c -- 1.8.2.3 -- 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
