Subject: [PATCH v38 01/24] x86/cpufeatures: x86/msr: Add Intel SGX hardware bits
Date: Tue, 15 Sep 2020 14:28:19 +0300 [thread overview]
Message-ID: <20200915112842.897265-2-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <20200915112842.897265-1-jarkko.sakkinen@linux.intel.com>
From: Sean Christopherson <sean.j.christopherson@intel.com>
Add X86_FEATURE_SGX from CPUID.(EAX=7, ECX=1), which informs whether the
CPU has SGX.
Add X86_FEATURE_SGX1 and X86_FEATURE_SGX2 from CPUID.(EAX=12H, ECX=0),
which describe the level of SGX support available [1].
Add IA32_FEATURE_CONTROL.SGX_ENABLE. BIOS can use this bit to opt-in SGX
before locking the feature control MSR [2].
[1] Intel SDM: 36.7.2 Intel® SGX Resource Enumeration Leaves
