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 v8: - Add reasons for using dt solution in dt-bindings. - Add locks for memory pin/unpin and relinquish operations. - Add VM memory stats in debugfs. - Add tracing support for hypercall and vcpu exit reasons. - Enable PTP for timing synchronization between host and guests. - Optimize memory performance for protected VMs. - Refactor wording and titles in documentation. Changes in v7: https://lore.kernel.org/all/20231116152756.4250-1-yi-de.wu@mediatek.com/ - Rebase these patches to the Linux 6.7-rc1 release. - Refactor patches 1 to 15 to improve coding style while ensuring they do not violate the majority of the changes made in v6 - Provide individual VM memory statistics within debugfs in patch 16. - Add tracing support for hyper call and vcpu exit_reason. Changes in v6: https://lore.kernel.org/all/20230919111210.19615-1-yi-de.wu@mediatek.com/ - Rebase based on kernel 6.6-rc1 - Keep dt solution and leave the reasons in the commit message - Remove arch/arm64/include/uapi/asm/gzvm_arch.h due to simplicity - Remove resampler in drivers/virt/geniezone/gzvm_irqfd.c due to defeature for now - Remove PPI in arch/arm64/geniezone/vgic.c - Refactor vm related components into 3 smaller patches, namely adding vm support, setting user memory region and checking vm capability - Refactor vcpu and vm component to remove unnecessary ARM prefix - Add demand paging to fix crash on destroying memory page, acclerate on booting and support ballooning deflate - Add memory pin/unpin memory mechanism to support protected VM - Add block-based demand paging for performance concern - Response to reviewers and fix coding style accordingly Changes in v5: https://lore.kernel.org/all/20230727080005.14474-1-yi-de.wu@mediatek.com/ - 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/all/20230609085214.31071-1-yi-de.wu@mediatek.com/ - 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.
