Subject: [PATCH v20 18/28] x86/sgx: ptrace() support for the SGX driver
Date: Wed, 17 Apr 2019 13:39:28 +0300 [thread overview]
Message-ID: <20190417103938.7762-19-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <20190417103938.7762-1-jarkko.sakkinen@linux.intel.com>
Add VMA callbacks for ptrace() that can be used with debug enclaves.
With debug enclaves data can be read and write the memory word at a time
by using ENCLS(EDBGRD) and ENCLS(EDBGWR) leaf instructions.
