Subject: [RFC PATCH 07/20] i386: Add SGX CPUID leaf FEAT_SGX_12_1_EBX
Date: Tue, 6 Aug 2019 11:56:36 -0700 [thread overview]
Message-ID: <20190806185649.2476-8-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20190806185649.2476-1-sean.j.christopherson@intel.com>
CPUID leaf 12_1_EBX is an Intel-defined feature bits leaf enumerating
the platform's SGX extended capabilities. Currently there is a single
capabilitiy:
- EXINFO: record information about #PFs and #GPs in the enclave's SSA
Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com>
