In case of nested Microsoft Hypervisor there are few privileged hypercalls which need to go L0 Hypervisor instead of L1 Hypervisor. This patches series basically identifies such hypercalls and replace them with nested hypercalls. Jinank Jain (5): mshv: Add support for detecting nested hypervisor hv: Setup synic registers in case of nested root partition hv: Add an interface to do nested hypercalls hv: Enable vmbus driver for nested root partition hv, mshv : Change interrupt vector for nested root partition arch/x86/include/asm/hyperv-tlfs.h | 17 +++++++- arch/x86/include/asm/idtentry.h | 2 + arch/x86/include/asm/irq_vectors.h | 6 +++ arch/x86/include/asm/mshyperv.h | 68 ++++++++++++++++++++++++++++-- arch/x86/kernel/cpu/mshyperv.c | 22 ++++++++++ arch/x86/kernel/idt.c | 9 ++++ drivers/hv/hv.c | 18 +++++--- drivers/hv/vmbus_drv.c | 5 ++- include/asm-generic/hyperv-tlfs.h | 1 + include/asm-generic/mshyperv.h | 1 + 10 files changed, 137 insertions(+), 12 deletions(-) -- 2.25.1
