Intel(R) Software Guard Extensions for Linux* OS

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.

This driver can be used to support earlier SGX-capable CPUs without Flexible Launch Control (FLC). However, please note that the ABI of this driver is diverged from the upstreaming SGX kernel patches and extra effort may be required to migrate software using this driver to future kernels with SGX support. To minimize ABI divergence and better align all SGX software stack with future SGX enabled kernel, no new features will be added to this driver. Support for distro/kernel versions other than those listed here will be considered on a case-by-case basis.

The DCAP driver has been developed to track closely with the upstreaming kernel patches, and support all SGX CPUs with FLC. Therefore, we recommend SGX community to start using the DCAP driver to minimize future impact from adopting new mainline kernels with SGX support.

For new feature requests/patches, please submit them directly to the linux-sgx mailing list

See License.txt for details.

Build and Install the Intel(R) SGX Driver

• Ensure that you have an operating system version supported as listed in releases: https://01.org/intel-software-guard-extensions/downloads
• Ensure that you have the following required hardware:
  • 6th Generation Intel(R) Core(TM) Processor or newer

  $ dpkg-query -s linux-headers-$(uname -r) 

  $ sudo apt-get install linux-headers-$(uname -r) 

  $ sudo yum install kernel-devel 

  $ sudo yum install kernel $ sudo reboot 

  $ sudo yum install elfutils-libelf-devel 

  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

  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:

  $ sudo mkdir -p "/lib/modules/"`uname -r`"/kernel/drivers/intel/sgx" $ sudo cp isgx.ko "/lib/modules/"`uname -r`"/kernel/drivers/intel/sgx" $ sudo sh -c "cat /etc/modules | grep -Fxq isgx || echo isgx >> /etc/modules" $ sudo /sbin/depmod $ sudo /sbin/modprobe isgx 

  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

  $ sudo /sbin/modprobe isgx --allow-unsupported 

  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:

  $ sudo /sbin/modprobe -r isgx $ sudo rm -rf "/lib/modules/"`uname -r`"/kernel/drivers/intel/sgx" $ sudo /sbin/depmod $ sudo /bin/sed -i '/^isgx$/d' /etc/modules

  How do I install the Intel Graphics driver in my system?

  Can someone help me out and explain or point me in the right direction on how to check video drivers and see if my video card running okay? I had 10.04 installed on my Thinkpad r61 with Compiz Manager and life was great, until the machine took water damage. I bought an ASUS (X54H) since and am trying out 12.04, but the desktop just doesn’t look right. I always struggled with video driver installation. There are no proprietary drivers available in the hardware manager. When I run lspci | grep VGA :

  00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 

  I will greatly appreciate your help. I want to use Linux more, but like I said video drivers appear to be my biggest concern. I have also tried 12.04 on my desktop PC, but again failed to configure video card, so switched back to Windows 7.

  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).

  Just to ensure it didn’t get removed by mistake (very slim possibility), just run this command:

  sudo apt-get install xserver-xorg-video-intel 

  If the driver is installed, and you’re still having issues with graphics on your desktop, then please file a bug report against the xorg package, using this terminal command:

  Установка драйвера Intel в Ubuntu

  В отличие от драйверов видеокарт от других производителей, таких как Nvidia и AMD, часть драйвера Intel для интегрированных видеокарт встроена в ядро, а другая часть в пакет mesa-utils. Таким образом если вы используете последнюю версию ядра и свежую версию mesa-utils то, скорее всего, вы используете самую свежую версию драйвера Intel.

  В этой статье мы рассмотрим как выполняется установка драйвера Intel в Ubuntu если он не установлен по умолчанию, а также как получить самую последнюю версию.

  Официальный установщик драйверов Intel

  Раньше существовал установщик драйверов от Intel, позволяющий установить последнюю версию драйвера в Ubuntu или Fedora, но потом компания прекратила поддержку этой утилиты. Скачать её можно здесь. Но последняя версия пакета вышла в 2018 году, и с тех пор уже вышло много новых ядер и новых версий дистрибутива Ubuntu. Сейчас в репозиториях Ubuntu версия драйвера более новая чем там.

  Установка драйвера Intel в Ubuntu

  Вы можете посмотреть какой сейчас драйвер видеокарты используется с помощью команды lspci:

  

  Как видите, в данном примере используется i915, это драйвер видеокарты от Intel. Он работает и ничего больше устанавливать не нужно. Если же в этой строчке находится что-то другое, можно попытаться установить драйвер.

  Для установки части драйвера для Xorg и Mesa достаточно установить в систему такие пакеты:

  sudo apt install xserver-xorg-video-intel

  sudo apt install mesa-utils

  

  Если вы хотите получить самую последнюю версию драйвера можно воспользоваться специальным PPA. Для добавления репозитория в систему выполните:

  sudo add-apt-repository ppa:oibaf/graphics-drivers

  Затем просто обновите систему и перезагрузите компьютер:

  Выводы

  Вот и все. Теперь вы знаете как выполняется установка драйвера Intel Ubuntu. В отличие от драйверов для Nvidia, в большинстве случаев здесь всё уже установлено. И вам не надо думать как поддерживать актуальную версию этого драйвера в своей системе. Если у вас остались вопросы, спрашивайте в комментариях!
