Subject: [PATCH v14 03/19] x86/cpufeature: Add SGX and SGX_LC CPU features
Date: Tue, 25 Sep 2018 16:06:40 +0300 [thread overview]
Message-ID: <20180925130845.9962-4-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <20180925130845.9962-1-jarkko.sakkinen@linux.intel.com>
From: Kai Huang <kai.huang@linux.intel.com>
Add X86_FEATURE_SGX and X86_FEATURE_SGX_LC that define the bits
determining whether the CPU supports SGX and user launch configuration
i.e. using a custom root key rather the Intel proprietary key for
enclave signing.
