"Intel Quick Sync Video" is the marketing name for the hardware video decoding and encoding features on Intel processors with integrated graphics. Neo provides OpenCL 1.2, 2.1 or 3.0 ( Tiger Lake and newer) depending on which iGPU you have. You will have a hard time getting them to work on other GNU/Linux distributions. Neo packages for Ubuntu only are available at /intel/compute-runtime/releases. Beignet did not provide more than OpenCL 1.2 for the older chips in question.īeignet has been replaced by a package called Neo ("new and improved OpenCL Driver stack"). The Mesa Clover OpenCL provides OpenCL 1.2 support for the older Intel graphics chips that are not supported by the newer Intel Neo driver. It is also not required and you should not bother trying to get an old Beignet package working on a modern distribution. Many GNU/Linux distributions have dropped the Beignet package since it is no longer maintained. This driver is required to get OpenCL on <=Gen7.5 graphics cards. Intel maintained an OpenCL driver called Beignet from 2013 to 2017. Vulkan is supported by a graphics driver called ANV. The i965 source is hosted at /(.)/drivers/dri/i965. It works on older chips too Broadwell (Gen (8) and newer is supported by the Intel Iris driver. Future Intel GPUs will supported by a new driver called Intel Iris. OpenGL on the user-space side is supported either the Mesa i915 driver or the i965, one of those will be used automatically depending on the GPU.
See the Troubleshooting section below for details. You may need kernel parameters like intel_idle.max_cstate=1 and/or i915.enable_dc=0 to have a problem-free experience with Intel graphics. There are issues with using the i915 kernel module in 5.3.x and 5.4.x kernels. It does not matter if a specific Intel iGPU is or is not listed, all of them are supported by this kernel module. The help text as of 5.2.20 states "(.) including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G, G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3, Core i5, Core i7 as well as Atom CPUs with integrated graphics.". While the module is called i915 it's actually a general driver for all Intel iGPUs. It is found under Device Drivers -> Graphics support -> Intel 8xx/9xx/G3x/G4x/HD Graphics in the kernel's make menuconfig. HD 610, 615, 620, 630, Iris Plus 640, Iris Plus 650Īll Intel iGPUs are supported by a kernel module called i915.
