Since Sean Christopherson has left Intel and i am responsible for Qemu SGX upstream work. His @intel.com address will be bouncing and his new email( seanjc@google.com) is also in CC lists. This series is Qemu SGX virtualization implementation rebased on latest Qemu release. The numa support for SGX will be sent in another patchset once this basic SGX patchset are merged. You can find Qemu repo here: https://github.com/intel/qemu-sgx.git upstream If you want to try SGX, you can directly install the linux release(at least 5.13.0-rc1+) since kvm SGX has been merged into linux release. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git To simplify, you'd better install linux on host and guest, which can support SGX on host and guest kernel. And to me, use below reference command to boot SGX guest: #qemu-system-x86_64 \ ...... \ -cpu host,+sgx-provisionkey \ -object memory-backend-epc,id=mem1,size=64M,prealloc=on \ -object memory-backend-epc,id=mem2,size=28M \ -M sgx-epc.id.0=epc1,sgx-epc.memdev.0=mem1,sgx-epc.id.1=epc2,sgx-epc.memdev.1=mem2 Overview ======== Intel Software Guard eXtensions (SGX) is a set of instructions and mechanisms for memory accesses in order to provide security accesses for sensitive applications and data. SGX allows an application to use it's pariticular address space as an *enclave*, which is a protected area provides confidentiality and integrity even in the presence of privileged malware. Accesses to the enclave memory area from any software not resident in the enclave are prevented, including those from privileged software. SGX virtaulization ================== The KVM SGX creates one new misc device, sgx_vepc, and Qemu will open '/dev/sgx_vepc' device node to mmap() host EPC memory to guest. The Qemu also adds 'sgx-epc' device to expose EPC sections to guest through CPUID and ACPI table. The Qemu SGX also supports multiple virtual EPC sections to guest, we just put them together physically contiguous for the sake of simplicity. The kernel SGX NUMA has been merged into Linux tip tree, we will support this function in the next phase. Although the current host SGX subsystem can not support SGX2 feature, the KVM/Qemu implementation still expose this feature to guest. Guest SGX2 support doesn't have interaction with host kernel SGX driver, the SGX guest can normally use those new instructions. As for SGX virtualization detailed infomation, please reference docs/intel-sgx.txt docuement(patch 33). Changelog: ========= (Changelog here is for global changes, please see each patch's changelog for changes made to specific patch.) v2-->v3: - Rebased the sgx patches into latest Qemu release. - Implemented the compound property for SGX, ref patch5, the command from '-sgx-epc' to '-M'. - Moved the sgx common code from sgx-epc.c to sgx.c. The sgx-epc.c is only responsible for virtual epc device. - Removed the previous patch13(linux-headers: Add placeholder for KVM_CAP_SGX_ATTRIBUTE) because ehabkost@redhat.com updated Linux headers to 5.13-rc4 with commit 278f064e452. - Updated the patch1 because ram_flags were changed by David Hildenbra. - Added one patch24, which avoid reset operation caused by bios reset. - Added one patch25, which make prealloc property consistent with Qemu cmdline during VM reset. v1-->v2: - Rebased the sgx patches into latest Qemu release. - Unified the "share" and "protected" arguments with ram_flags in the memory_region_init_ram_from_fd()(Paolo). - Added the new MemoryBackendEpcProperties and related documents(Eric Blake). - Changed the KVM_CAP_SGX_ATTRIBUTE from 195 to 196(Kai). - Changed the version and some grammar issues(Eric Blake).
