[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v2 00/26] Disable domctl-op via CONFIG_MGMT_HYPERCALLS
It can be beneficial for some dom0less systems to further reduce Xen footprint via disabling some hypercalls handling code, which may not to be used & required in such systems. We are introducing a new single Kconfig CONFIG_MGMT_HYPERCALLS to manage such hypercalls. We are trying to disable hypercalls in the following aspects: - sysctl - domctl - hvm - physdev - platform This patch serie is only focusing on domctl-op. Different aspects will be covered in different patch serie. Features, like VM event, or paging log-dirty support, which fully rely on domctl-op, will be wrapped with CONFIG_MGMT_HYPERCALLS, to reduce Xen footprint as much as possible. It is derived from Stefano Stabellini's commit "xen: introduce kconfig options to disable hypercalls"( https://lore.kernel.org/xen-devel/20241219092917.3006174-1-Sergiy_Kibrik@xxxxxxxx) Penny Zheng (26): xen/x86: move domctl.o out of PV_SHIM_EXCLUSIVE xen/sysctl: replace CONFIG_SYSCTL with CONFIG_MGMT_DOMCTL xen/x86: consolidate vram tracking support xen: consolidate CONFIG_VM_EVENT xen/x86: make VM_EVENT depend on CONFIG_MGMT_HYPERCALLS xen/xsm: wrap xsm_vm_event_control() with CONFIG_VM_EVENT xen/domctl: wrap domain_pause_by_systemcontroller() with MGMT_HYPERCALLS xen/domctl: wrap domain_soft_reset() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap domain_resume() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap domain_kill() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap domain_set_node_affinity() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap vcpu_affinity_domctl() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap sched_adjust() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap arch-specific arch_get_info_guest() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap xsm_{irq_permission,iomem_permission} with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap arch-specific domain_set_time_offset() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap xsm_set_target() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap xsm_getdomaininfo() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap set_global_virq_handler() with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap iommu-related domctl op with CONFIG_MGMT_HYPERCALLS xen/xsm: wrap xsm-iommu-related functions with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap arch_{get,set}_paging_mempool_size() with CONFIG_MGMT_HYPERCALLS xen/x86: make CONFIG_X86_PSR depend on CONFIG_MGMT_HYPERCALLS xen/domctl: wrap arch-specific domctl-op with CONFIG_MGMT_HYPERCALLS xen/xsm: wrap xsm functions with CONFIG_MGMT_HYPERCALLS xen/domctl: wrap common/domctl.c with CONFIG_MGMT_HYPERCALLS xen/Kconfig.debug | 4 +- xen/arch/arm/Makefile | 2 +- xen/arch/arm/arm32/Makefile | 2 +- xen/arch/arm/arm64/Makefile | 2 +- xen/arch/arm/domain.c | 5 ++ xen/arch/arm/include/asm/tee/tee.h | 2 + xen/arch/arm/mmu/p2m.c | 8 +++ xen/arch/arm/mpu/p2m.c | 2 + xen/arch/arm/tee/ffa.c | 4 ++ xen/arch/arm/tee/optee.c | 4 ++ xen/arch/arm/tee/tee.c | 2 + xen/arch/arm/time.c | 2 + xen/arch/riscv/stubs.c | 4 +- xen/arch/x86/Kconfig | 1 + xen/arch/x86/Makefile | 6 +- xen/arch/x86/configs/pvshim_defconfig | 2 +- xen/arch/x86/domain.c | 4 ++ xen/arch/x86/emul-i8254.c | 2 + xen/arch/x86/hvm/Makefile | 4 +- xen/arch/x86/hvm/hvm.c | 4 ++ xen/arch/x86/hvm/pmtimer.c | 2 + xen/arch/x86/hvm/save.c | 2 + xen/arch/x86/hvm/svm/svm.c | 8 +++ xen/arch/x86/hvm/vmx/vmx.c | 16 +++++ xen/arch/x86/include/asm/hvm/hvm.h | 20 +++++++ xen/arch/x86/include/asm/hvm/monitor.h | 65 ++++++++++++++++++++- xen/arch/x86/include/asm/hvm/vm_event.h | 4 ++ xen/arch/x86/include/asm/mem_access.h | 9 +++ xen/arch/x86/include/asm/monitor.h | 7 +++ xen/arch/x86/include/asm/p2m.h | 6 +- xen/arch/x86/include/asm/paging.h | 34 +++++------ xen/arch/x86/mm/hap/hap.c | 4 +- xen/arch/x86/mm/mem_sharing.c | 4 ++ xen/arch/x86/mm/p2m-pod.c | 2 + xen/arch/x86/mm/p2m.c | 30 ++++++++++ xen/arch/x86/mm/paging.c | 36 ++---------- xen/arch/x86/psr.c | 18 ------ xen/arch/x86/time.c | 2 + xen/common/Kconfig | 22 +++---- xen/common/Makefile | 7 +-- xen/common/argo.c | 2 + xen/common/device-tree/device-tree.c | 2 + xen/common/domain.c | 10 ++++ xen/common/event_channel.c | 2 + xen/common/grant_table.c | 2 + xen/common/page_alloc.c | 8 +-- xen/common/perfc.c | 4 +- xen/common/sched/arinc653.c | 10 ++-- xen/common/sched/core.c | 10 ++-- xen/common/sched/cpupool.c | 16 ++--- xen/common/sched/credit.c | 10 +++- xen/common/sched/credit2.c | 10 +++- xen/common/sched/private.h | 6 +- xen/common/sched/rt.c | 4 ++ xen/common/spinlock.c | 4 +- xen/drivers/char/console.c | 4 +- xen/drivers/passthrough/amd/pci_amd_iommu.c | 8 +++ xen/drivers/passthrough/arm/ipmmu-vmsa.c | 6 ++ xen/drivers/passthrough/arm/smmu-v3.c | 4 ++ xen/drivers/passthrough/arm/smmu.c | 4 ++ xen/drivers/passthrough/device_tree.c | 6 ++ xen/drivers/passthrough/iommu.c | 2 + xen/drivers/passthrough/pci.c | 6 ++ xen/drivers/passthrough/vtd/iommu.c | 6 ++ xen/include/hypercall-defs.c | 14 ++--- xen/include/xen/domain.h | 13 +++-- xen/include/xen/mem_access.h | 35 ++++++++++- xen/include/xen/monitor.h | 8 ++- xen/include/xen/vm_event.h | 24 +++++++- xen/include/xsm/xsm.h | 58 +++++++++++++----- xen/lib/x86/Makefile | 2 +- xen/xsm/dummy.c | 16 ++--- xen/xsm/flask/hooks.c | 44 +++++++------- 73 files changed, 522 insertions(+), 202 deletions(-) -- 2.34.1
