[PATCH v10 1/5] qemu: provide support to query the SGX capability

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



QEMU version >= 6.2.0 provides support for creating enclave on
SGX x86 platform using Software Guard Extensions (SGX) feature.
This patch adds support to query the SGX capability from the qemu.
