Subject: [PATCH 01/10] x86: add SGX Launch Control definition to cpufeature
Date: Mon, 8 May 2017 17:24:24 +1200 [thread overview]
Message-ID: <20170508052434.3627-2-kai.huang@linux.intel.com> (raw)
In-Reply-To: <20170508052434.3627-1-kai.huang@linux.intel.com>
For Intel CPU that supports SGX Launch Control, CPUID.0x7.0:ECX[bit 30] reports
the availability of 1-setting of bit 17 of IA32_FEATURE_CONTROL MSR, which
enables runtime configuration of SGX Launch Control via IA32_SGXLEPUBKEYHASHn.
