The following patchset adds to QEMU the supporting for macOS's native hypervisor, Hypervisor.framework (hvf). The code base is taken from Google's Android emulator at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev.
Apart from general code refactoring, some additional features were implemented: retrieve the set of features supported by host cpu and hvf (cpuid); dirty page tracking for VGA memory area; reimplementation of the event injection mechanism to allow injection of exceptions during vmexits, which is exemplified by the injection of a GP fault when the guest vmexits due to execution of the vmcall instruction; changing the emulator's use of CPUState structure in favor of CPUX86State, so as to in the future remove data structures that are uselessly specific to hvf and unified some of the state between kvm/tcg and hvf. Some features initially planned to implement that didn't make it include: page fault handling in the emulator and implementing the dummy_signal to handle the SIG_IPI signal without race conditions. Hopefully these can be implemented in the near future. Sergio Andres Gomez Del Real (14): hvf: add support for Hypervisor.framework in the configure script hvf: add code base from Google's QEMU repository hvf: add conditional macros around hvf code in cpus.c hvf: add fields to CPUState and CPUX86State; add definitions hvf: use new helper functions for put/get xsave hvf: add compilation rules to Makefile.objs hvf: run hvf code through checkpatch.pl and fix style issues apic: add function to apic that will be used by hvf hvf: implement hvf_get_supported_cpuid hvf: refactor cpuid code hvf: implement vga dirty page tracking hvf: move fields from CPUState to CPUX86State hvf: refactor event injection code for hvf hvf: inject General Protection Fault when vmexit through vmcall configure | 32 + cpus.c | 107 +- hw/intc/apic.c | 11 + include/hw/i386/apic.h | 1 + include/qom/cpu.h | 2 + include/sysemu/hvf.h | 106 ++ qemu-options.hx | 20 +- target/i386/Makefile.objs | 1 + target/i386/cpu-qom.h | 4 +- target/i386/cpu.c | 111 +- target/i386/cpu.h | 30 + target/i386/hvf-all.c | 1123 ++++++++++++++++++ target/i386/hvf-i386.h | 48 + target/i386/hvf-utils/Makefile.objs | 1 + target/i386/hvf-utils/README.md | 7 + target/i386/hvf-utils/vmcs.h | 371 ++++++ target/i386/hvf-utils/vmx.h | 222 ++++ target/i386/hvf-utils/x86.c | 184 +++ target/i386/hvf-utils/x86.h | 476 ++++++++ target/i386/hvf-utils/x86_cpuid.c | 417 +++++++ target/i386/hvf-utils/x86_cpuid.h | 52 + target/i386/hvf-utils/x86_decode.c | 2186 +++++++++++++++++++++++++++++++++++ target/i386/hvf-utils/x86_decode.h | 325 ++++++ target/i386/hvf-utils/x86_descr.c | 124 ++ target/i386/hvf-utils/x86_descr.h | 55 + target/i386/hvf-utils/x86_emu.c | 1536 ++++++++++++++++++++++++ target/i386/hvf-utils/x86_emu.h | 32 + target/i386/hvf-utils/x86_flags.c | 333 ++++++ target/i386/hvf-utils/x86_flags.h | 243 ++++ target/i386/hvf-utils/x86_gen.h | 36 + target/i386/hvf-utils/x86_mmu.c | 273 +++++ target/i386/hvf-utils/x86_mmu.h | 28 + target/i386/hvf-utils/x86hvf.c | 463 ++++++++ target/i386/hvf-utils/x86hvf.h | 22 + target/i386/kvm.c | 2 - vl.c | 7 + 36 files changed, 8957 insertions(+), 34 deletions(-) create mode 100644 include/sysemu/hvf.h create mode 100644 target/i386/hvf-all.c create mode 100644 target/i386/hvf-i386.h create mode 100644 target/i386/hvf-utils/Makefile.objs create mode 100644 target/i386/hvf-utils/README.md create mode 100644 target/i386/hvf-utils/vmcs.h create mode 100644 target/i386/hvf-utils/vmx.h create mode 100644 target/i386/hvf-utils/x86.c create mode 100644 target/i386/hvf-utils/x86.h create mode 100644 target/i386/hvf-utils/x86_cpuid.c create mode 100644 target/i386/hvf-utils/x86_cpuid.h create mode 100644 target/i386/hvf-utils/x86_decode.c create mode 100644 target/i386/hvf-utils/x86_decode.h create mode 100644 target/i386/hvf-utils/x86_descr.c create mode 100644 target/i386/hvf-utils/x86_descr.h create mode 100644 target/i386/hvf-utils/x86_emu.c create mode 100644 target/i386/hvf-utils/x86_emu.h create mode 100644 target/i386/hvf-utils/x86_flags.c create mode 100644 target/i386/hvf-utils/x86_flags.h create mode 100644 target/i386/hvf-utils/x86_gen.h create mode 100644 target/i386/hvf-utils/x86_mmu.c create mode 100644 target/i386/hvf-utils/x86_mmu.h create mode 100644 target/i386/hvf-utils/x86hvf.c create mode 100644 target/i386/hvf-utils/x86hvf.h -- 2.14.1 Subject: [PATCH 00/15]
