Red Hat recommend disabling hardware acceleration on all processors with Intel integrated graphcis due to this flaw. gen7 and gen7.5 chips are still vulnerable to that hardware flaw. #Intel graphics driver update for linux Patch#The kernel got a patch which implemented that same workaround for gen9 graphics chips in January 2020. A workaround for this flaw has been in place for gen8 graphics chips since 2017. Intel integrated graphics chips have a hardware flaw which allows one process to get data from another process. #Intel graphics driver update for linux driver#If you have an old distributions and an old Intel GPU and you experience crashes when playing VP9 video then this driver is probably the reason. However, there has been some problems with earlier versions of it that have caused Chromium and mpv to crash when VP9 was played using this driver. The "Hybrid" VAAPI driver ( libva-intel-hybrid-driver) works fine as of version 1.0.2. vainfo show a VAProfileVP9Profile0: VAEntrypointVLD in the list of supported codecs on these machines only if the hybrid driver is present, VP9 hardware decoding will not be supported without this driver. This "hybrid" driver will, in theory, let you do partial VP9 hardware video decoding on certain older Intel iGPUs (Haswell/Broadwell). Intel offers a special "hybrid" VAAPI driver, typically available as libva-intel-hybrid-driver, in addition to the standard libva-intel-driver driver for hardware decoding/encoding using VAAPI. Kaby Lake, Gemini Lake, Coffee Lake, Comet Lake, Cannon Lake vainfo will tell you the capabilities of the iGPU you have on your system. You will also want a package called libva-utils which contains the vainfo utility. You need libva and a driver package typically called libva-intel-driver to use GPU hardware decoding and encoding on Intel hardware. Processors with an Intel iGPU can be used to do hardware video encoding in programs like OBS Studio as long as you have libva installed and the processors iGPU supports the video codec and resolution you want to use. "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. #Intel graphics driver update for linux drivers#It is found under Device Drivers -> Graphics support -> Intel 8xx/9xx/G3x/G4x/HD Graphics in the kernel's make menuconfig. #Intel graphics driver update for linux plus#HD 610, 615, 620, 630, Iris Plus 640, Iris Plus 650Īll Intel iGPUs are supported by a kernel module called i915.
