This series is based on linux-next, tag: next-20230726. GenieZone hypervisor(gzvm) is a type-1 hypervisor that supports various virtual machine types and provides security features such as TEE-like scenarios and secure boot. It can create guest VMs for security use cases and has virtualization capabilities for both platform and interrupt. Although the hypervisor can be booted independently, it requires the assistance of GenieZone hypervisor kernel driver(gzvm-ko) to leverage the ability of Linux kernel for vCPU scheduling, memory management, inter-VM communication and virtio backend support. Changes in v5: - Add dt solution back for device initialization - Add GZVM_EXIT_GZ reason for gzvm_vcpu_run() - Add patch for guest page fault handler - Add patch for supporitng pin/unpin memory - Remove unused enum members, namely GZVM_FUNC_GET_REGS and GZVM_FUNC_SET_REGS - Use dev_debug() for debugging when platform device is available, and use pr_debug() otherwise - Response to reviewers and fix bugs accordingly Changes in v4: https://lore.kernel.org/lkml/20230609085214.31071-1-yi-de.wu@xxxxxxxxxxxx/ - Add macro to set VM as protected without triggering pvmfw in AVF. - Add support to pass dtb config to hypervisor. - Add support for virtual timer. - Add UAPI to pass memory region metadata to hypervisor. - Define our own macros for ARM's interrupt number - Elaborate more on GenieZone hyperivsor in documentation - Fix coding style. - Implement our own module for coverting ipa to pa - Modify the way of initializing device from dt to a more discoverable way - Move refactoring changes into indepedent patches. Changes in v3: https://lore.kernel.org/all/20230512080405.12043-1-yi-de.wu@xxxxxxxxxxxx/ - Refactor: separate arch/arm64/geniezone/gzvm_arch.c into vm.c/vcpu.c/vgic.c - Remove redundant functions - Fix reviewer's comments Changes in v2: https://lore.kernel.org/all/20230428103622.18291-1-yi-de.wu@xxxxxxxxxxxx/ - Refactor: move to drivers/virt/geniezone - Refactor: decouple arch-dependent and arch-independent - Check pending signal before entering guest context - Fix reviewer's comments Initial Commit in v1: https://lore.kernel.org/all/20230413090735.4182-1-yi-de.wu@xxxxxxxxxxxx/ Yi-De Wu (12): docs: geniezone: Introduce GenieZone hypervisor dt-bindings: hypervisor: Add MediaTek GenieZone hypervisor virt: geniezone: Add GenieZone hypervisor support virt: geniezone: Add vcpu support virt: geniezone: Add irqchip support for virtual interrupt injection virt: geniezone: Add irqfd support virt: geniezone: Add ioeventfd support virt: geniezone: Add memory region support virt: geniezone: Add dtb config support virt: geniezone: Add virtual timer support virt: geniezone: Add guest page fault handler virt: geniezone: Add memory pin/unpin support .../hypervisor/mediatek,geniezone-hyp.yaml | 31 + Documentation/virt/geniezone/introduction.rst | 86 +++ Documentation/virt/index.rst | 1 + MAINTAINERS | 13 + arch/arm64/Kbuild | 1 + arch/arm64/geniezone/Makefile | 9 + arch/arm64/geniezone/driver.c | 26 + arch/arm64/geniezone/gzvm_arch_common.h | 130 ++++ arch/arm64/geniezone/vcpu.c | 155 +++++ arch/arm64/geniezone/vgic.c | 124 ++++ arch/arm64/geniezone/vm.c | 251 ++++++++ arch/arm64/include/uapi/asm/gzvm_arch.h | 58 ++ drivers/virt/Kconfig | 2 + drivers/virt/geniezone/Kconfig | 16 + drivers/virt/geniezone/Makefile | 12 + drivers/virt/geniezone/gzvm_common.h | 12 + drivers/virt/geniezone/gzvm_exception.c | 34 ++ drivers/virt/geniezone/gzvm_hvc.c | 34 ++ drivers/virt/geniezone/gzvm_ioeventfd.c | 273 +++++++++ drivers/virt/geniezone/gzvm_irqfd.c | 566 ++++++++++++++++++ drivers/virt/geniezone/gzvm_main.c | 154 +++++ drivers/virt/geniezone/gzvm_mmu.c | 210 +++++++ drivers/virt/geniezone/gzvm_vcpu.c | 280 +++++++++ drivers/virt/geniezone/gzvm_vm.c | 488 +++++++++++++++ include/linux/gzvm_drv.h | 185 ++++++ include/uapi/asm-generic/Kbuild | 1 + include/uapi/asm-generic/gzvm_arch.h | 13 + include/uapi/linux/gzvm.h | 362 +++++++++++ 28 files changed, 3527 insertions(+) create mode 100644 Documentation/devicetree/bindings/hypervisor/mediatek,geniezone-hyp.yaml create mode 100644 Documentation/virt/geniezone/introduction.rst create mode 100644 arch/arm64/geniezone/Makefile create mode 100644 arch/arm64/geniezone/driver.c create mode 100644 arch/arm64/geniezone/gzvm_arch_common.h create mode 100644 arch/arm64/geniezone/vcpu.c create mode 100644 arch/arm64/geniezone/vgic.c create mode 100644 arch/arm64/geniezone/vm.c create mode 100644 arch/arm64/include/uapi/asm/gzvm_arch.h create mode 100644 drivers/virt/geniezone/Kconfig create mode 100644 drivers/virt/geniezone/Makefile create mode 100644 drivers/virt/geniezone/gzvm_common.h create mode 100644 drivers/virt/geniezone/gzvm_exception.c create mode 100644 drivers/virt/geniezone/gzvm_hvc.c create mode 100644 drivers/virt/geniezone/gzvm_ioeventfd.c create mode 100644 drivers/virt/geniezone/gzvm_irqfd.c create mode 100644 drivers/virt/geniezone/gzvm_main.c create mode 100644 drivers/virt/geniezone/gzvm_mmu.c create mode 100644 drivers/virt/geniezone/gzvm_vcpu.c create mode 100644 drivers/virt/geniezone/gzvm_vm.c create mode 100644 include/linux/gzvm_drv.h create mode 100644 include/uapi/asm-generic/gzvm_arch.h create mode 100644 include/uapi/linux/gzvm.h -- 2.18.0
