For this, common Hyper-V code is refactored, necessary support is added, mshv_vtl_main.c is refactored and then finally support is added in Kconfig. Based on commit 1f318b96cc84 ("Linux 7.0-rc3") Naman Jain (11): arch: arm64: Export arch_smp_send_reschedule for mshv_vtl module Drivers: hv: Move hv_vp_assist_page to common files Drivers: hv: Add support to setup percpu vmbus handler Drivers: hv: Refactor mshv_vtl for ARM64 support to be added drivers: hv: Export vmbus_interrupt for mshv_vtl module Drivers: hv: Make sint vector architecture neutral in MSHV_VTL arch: arm64: Add support for mshv_vtl_return_call Drivers: hv: mshv_vtl: Move register page config to arch-specific files Drivers: hv: mshv_vtl: Let userspace do VSM configuration Drivers: hv: Add support for arm64 in MSHV_VTL Drivers: hv: Kconfig: Add ARM64 support for MSHV_VTL arch/arm64/hyperv/Makefile | 1 + arch/arm64/hyperv/hv_vtl.c | 152 ++++++++++++++++++++++ arch/arm64/hyperv/mshyperv.c | 13 ++ arch/arm64/include/asm/mshyperv.h | 28 ++++ arch/arm64/kernel/smp.c | 1 + arch/x86/hyperv/hv_init.c | 88 +------------ arch/x86/hyperv/hv_vtl.c | 130 +++++++++++++++++++ arch/x86/include/asm/mshyperv.h | 8 +- drivers/hv/Kconfig | 2 +- drivers/hv/hv_common.c | 99 +++++++++++++++ drivers/hv/mshv.h | 8 -- drivers/hv/mshv_vtl_main.c | 205 ++++-------------------------- drivers/hv/vmbus_drv.c | 8 +- include/asm-generic/mshyperv.h | 49 +++++++ include/hyperv/hvgdk_mini.h | 2 + 15 files changed, 505 insertions(+), 289 deletions(-) create mode 100644 arch/arm64/hyperv/hv_vtl.c base-commit: 1f318b96cc84d7c2ab792fcc0bfd42a7ca890681 prerequisite-patch-id: 24022ec1fb63bc20de8114eedf03c81bb1086e0e prerequisite-patch-id: 801f2588d5c6db4ceb9a6705a09e4649fab411b1 prerequisite-patch-id: 581c834aa268f0c54120c6efbc1393fbd9893f49 prerequisite-patch-id: b0b153807bab40860502c52e4a59297258ade0db prerequisite-patch-id: 2bff6accea80e7976c58d80d847cd33f260a3cb9 prerequisite-patch-id: 296ffbc4f119a5b249bc9c840f84129f5c151139 prerequisite-patch-id: 3b54d121145e743ac5184518df33a1812280ec96 prerequisite-patch-id: 06fc5b37b23ee3f91a2c8c9b9c126fde290834f2 prerequisite-patch-id: 6e8afed988309b03485f5538815ea29c8fa5b0a9 prerequisite-patch-id: 4f1fb1b7e9cfa8a3b1c02fafecdbb432b74ee367 prerequisite-patch-id: 49944347e0b2d93e72911a153979c567ebb7e66b prerequisite-patch-id: 6dec75498eeae6365d15ac12b5d0a3bd32e9f91c -- 2.43.0
