support three displays simultaneously. Asus H87-based motherboards are also advertised to support three independent monitors at once. Capabilities (GPU hardware) OpenCL 2.1 and 2.2 possible with software update on OpenCL 2.0 hardware (Broadwell+) with future software updates. Support for Direct3D 9 in Mesa is only implemented for Gallium3D-style drivers, and is thus only available with the newer Gallium3D Iris driver, which is the default for Broadwell+ since Mesa 20.0. It is not supported in the classic Mesa i965 driver. The classic Mesa i965 driver, which is the only one for Haswell and older on Linux, only supports core profile for OpenGL 3.1+, not compatibility profile. The Iris Gallium3D driver supports compatibility profile for OpenGL 4.6. All GVT virtualization methods are supported since the Broadwell processor family with KVM and Xen. Capabilities (GPU video acceleration) Intel developed a dedicated SIP core which implements multiple video decompression and compression algorithms branded Intel Quick Sync Video. Some are implemented completely, some only partially. Hardware-accelerated algorithms Intel Pentium and Celeron family Intel Atom family Documentation Intel releases programming manuals for most of Intel HD Graphics devices via its Open Source Technology Center. This allows various open source enthusiasts and hackers to contribute to driver development, and port drivers to various operating systems, without the need for reverse engineering.
