Diff to v14: - Dropped SGX support for QEMU 6.2.0, only focus on QEMU 7.0.0 (BTW, I noticed the default QEMU version in RHEL9 is still 6.2.0, so those user cannot access this feature unless manually upgrade QEMU) - Removed total EPC size from domain capability, since the corresponding attribute is marked as deprecated in QMP command "query-sgx-capabilities" - Some cleanups to address comments (pin test to 7.0.0, more validations on qemu_validate.c, name issue, use built-in functions, ...)
BTW, it still adds SGX EPC as memory device, since basically SGX EPC is one kind of memory. More specifically, a private region of memory, so didn't add additional general memory. QEMU allocate part of them and pass through to guest VM. I don't have a better alternative to represent it in domain definition.
Any comments will be highly appreciated! Thanks, Lin Yang.
