The [linux-sgx-driver](https://github.com/01org/linux-sgx-driver) project hosts the out-of-tree driver for the Linux Intel(R) SGX software stack, which will be used until the driver upstreaming process is complete.
Within the linux-sgx-driver project, two versions of the out-of-tree driver are provided. Both versions are compatible with the linux-sgx PSW and SDK:
- SGX 2.0 Linux Driver (sgx2)
* The sgx2 branch of the linux-sgx-driver project contains the SGX 2.0 Linux Driver. This driver has additional support for SGX 2.0-based features available in upcoming CPUs. This driver has the same behavior as the SGX Linux Driver (master) on CPUs without SGX 2.0 support.
- SGX Linux Driver (master)
* The master branch of the linux-sgx-driver project tracks the proposed upstream version of the SGX driver and does not yet support SGX 2.0-based features.

Starting from 05/2017, we are importing the sgx driver code from the in-kernel sgx repository located at git-hub: https://github.com/jsakkine-intel/linux-sgx.git. Any contribution should be done there. Future versions of the sgx driver code will be imported later on. The motivation behind this decision is to maintain a single source code of the sgx linux driver.
An additional directory inker2ext/ has been created, it contains a script and a patch file that can be used in order to separately generate the code base of the sgx external module; it can be used in case someone wants the newest sgx driver as an external module and does not want to wait for next update.
The sgx2 branch hosts an initial implementation supporting SGX 2.0. This patch is maintained in inker2ext/sgx2.patch in the 2.0 branch and will be periodically rebased to take updates from the linux-sgx-driver:master branch. Contributions for this patch should be managed directly through the linux-sgx-driver project on Github.
