Externally we follow Microsoft's convention of calling Linux the "root partition" in this setup. "Dom0" is an internal term. We drew parallels to Xen at the beginning of the project. > Magnus Kulke (26): > accel: Add Meson and config support for MSHV accelerator > target/i386/emulate: Allow instruction decoding from stream > target/i386/mshv: Add x86 decoder/emu implementation > hw/intc: Generalize APIC helper names from kvm_* to accel_* > include/hw/hyperv: Add MSHV ABI header definitions > linux-headers/linux: Add mshv.h headers > accel/mshv: Add accelerator skeleton > accel/mshv: Register memory region listeners > accel/mshv: Initialize VM partition > accel/mshv: Add vCPU creation and execution loop > accel/mshv: Add vCPU signal handling > target/i386/mshv: Add CPU create and remove logic > target/i386/mshv: Implement mshv_store_regs() > target/i386/mshv: Implement mshv_get_standard_regs() > target/i386/mshv: Implement mshv_get_special_regs() > target/i386/mshv: Implement mshv_arch_put_registers() > target/i386/mshv: Set local interrupt controller state > target/i386/mshv: Register CPUID entries with MSHV > target/i386/mshv: Register MSRs with MSHV > target/i386/mshv: Integrate x86 instruction decoder/emulator > target/i386/mshv: Write MSRs to the hypervisor > target/i386/mshv: Implement mshv_vcpu_run() > accel/mshv: Handle overlapping mem mappings > target/i386/mshv: Use preallocated page for hvcall > docs: Add mshv to documentation > MAINTAINERS: Add maintainers for mshv accelerator > > Praveen K Paladugu (1): > qapi/accel: Allow to query mshv capabilities > I've gone through this patch series and it generally looks good to me.
