Subject: [PATCH v20 10/28] x86/sgx: Add SGX1 and SGX2 architectural data structures
Date: Wed, 17 Apr 2019 13:39:20 +0300
Message-ID: <20190417103938.7762-11-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <20190417103938.7762-1-jarkko.sakkinen@linux.intel.com>

Define the data structures used by various ENCLS functions needed for
Linux to support all SGX1 and SGX2 ENCLS leaf functions.  This is not
an exhaustive representation of all SGX data structures as several are
only consumed by ENCLU (userspace), e.g. REPORT and KEYREQUEST, while
others are only consumed by future features, e.g. RDINFO.
