Install Intel Opencl Driver Linux

To build igb driver with DCA: If your kernel supports DCA, the driver will build by default with DCA enabled. Install the Linux. e1000e base driver for Intel® Gigabit Ethernet Network Connection. The Linux. e1000e driver supports PCI Express. Gigabit Network Connections except the 82575, 82576, 82580, I350, I354, and I210/I211.

  • This process isn't as easy on a Linux operating system. For one reason, Linux is an open source operating system, so there are hundreds of Linux distribution variations. This means it's impossible to create one how-to guide that works for all Linux distros. Each Linux operating system handles the driver installation process a different way.
  • Nov 19, 2011  Now the real problem is this, My ignorance on Linux, I just changed my SO to Ubuntu 11.10, and i dont know how to install the drivers. Usually i just had to execute a 'Install.exe' on Windows. But now on Linux, i cant find the way to install it.
  • The Intel graphics driver is part of the xserver-xorg-video-intel driver package, which is installed on all Ubuntu systems by default. And since it isn't a proprietary driver package, it doesn't show up in jockey (aka the Hardware Drivers application).

Introduction

Intel(R) Software Guard Extensions (Intel(R) SGX) is an Intel technology for application developers seeking to protect select code and data from disclosure or modification.

The Linux SGX software stack is comprised of the Intel(R) SGX driver, the Intel(R) SGX SDK, and the Intel(R) SGX Platform Software. The Intel(R) SGX SDK and Intel(R) SGX PSW are hosted in the linux-sgx project.

The 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 branch)
    • 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 1.5 Linux Driver (master) on CPUs without SGX 2.0 support.
  • SGX 1.5 Linux Driver (master branch)
    • The master branch of the linux-sgx-driver project tracks the proposed upstream version of the SGX 1.5 driver and does not yet support SGX 2.0-based features.

IMPORTANT:

Linux

Starting from 5/10/2019, the master branch (which supports only SGX 1.5-based features) is deprecated and is not supported anymore. Please use the sgx2 branch; it is a super set of the master branch.

Contributing

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.

Build and Install the Intel(R) SGX Driver

Prerequisites

  • Ensure that you have the following required operating systems:
    • Ubuntu* 16.04.3 LTS Desktop 64bits
    • Ubuntu* 16.04.3 LTS Server 64bits
    • Red Hat Enterprise Linux Server release 7.4 64bits
    • CentOS 7.4.1708 64bits
    • SUSE Linux Enterprise Server 12 64bits
  • Ensure that you have the following required hardware:
    • 6th Generation Intel(R) Core(TM) Processor or newer
  • Configure the system with the SGX hardware enabled option.
  • To build the driver, the version of installed kernel headers must match the active kernel version on the system.
    • On Ubuntu
      • To check if matching kernel headers are installed:
      • To install matching headers:
    • On CentOS and RHEL
      • To check if matching kernel headers are installed:
      • To install matching headers:
      • After the above command, if the matching headers are still missing in /usr/src/kernels, try update kernel and reboot usig commands below. Then choose updated kernel on boot menu.

Note: Refer to the 'Intel® SGX Resource Enumeration Leaves' section in the Intel SGX Programming reference guide to make sure your cpu has the SGX feature.

Build the Intel(R) SGX Driver

Note: To use the SGX 2.0 driver, checkout or download the sgx2 branch and then follow the build instructions.

To build Intel(R) SGX driver, change the directory to the driver path and enter the following command:

You can find the driver isgx.ko generated in the same directory.

Install the Intel(R) SGX Driver

To install the Intel(R) SGX driver, enter the following command with root privilege:

On Red Hat Enterprise Linux Server or CentOS, need to run below command on each reboot

On SUSE, need to add '--allow-unsupported' flag when executing 'modprobe' command during the SGX driver intallation and on each reboot

Uninstall the Intel(R) SGX Driver

Before uninstall the Intel(R) SGX driver, make sure the aesmd service is stopped. See the topic, Start or Stop aesmd Service, on how to stop the aesmd service.
To uninstall the Intel(R) SGX driver, enter the following commands:
