'''AMDgpu''' is an [[open source]] [[device driver]] for the [[Linux]] operating system developed by [[AMD]] to support its [[Radeon]] lineup of [[graphics card]]s (GPUs). It was announced in 2014 as the successor to the previous <code>radeon</code> device driver as part of AMD's new "unified" driver strategy,<ref>{{Cite web |last=Larabel |first=Michael |date=October 8, 2014 |title=The Slides Announcing The New "AMDGPU" Kernel Driver |url=https://www.phoronix.com/news/MTgwODA |access-date=April 11, 2023 |website=Phoronix |language=en}}</ref> and was released on April 20, 2015.<ref>{{Cite web |last=Larabel |first=Michael |date=April 20, 2015 |title=AMD Releases New "AMDGPU" Linux Kernel Driver & Mesa Support |url=https://www.phoronix.com/news/AMD-AMDGPU-Released |access-date=April 11, 2023 |website=Phoronix |language=en}}</ref>

'''AMDgpu''' is [[AMD]]'s fully [[Open-source software|open source]] unified [[device driver|kernel driver]] for its GPUs on [[Linux]].

It takes the form of an [https://www.kernel.org/doc/html/latest/gpu/amdgpu/index.html in-tree] [[Loadable kernel module|kernel module]].

As of 2022, AMD Kernel Fusion Driver ('''KFD''') is now integrated in this one kernel module. AMD KFD development at AMD is part of [[ROCm#ROCk_-_Kernel_driver|ROCm]], under the ROCk project.

==Community==

The development of the kernel module happens first internally atbetween AMD, and discussion with the Linux maintainers, discussions happen on the [[freedesktop.org]] mailing lists<ref>{{Cite web|title=The dri-devel Archives|url=https://lists.freedesktop.org/archives/dri-devel/|access-date=2021-02-01}}</ref><ref>{{Cite web|title=The amd-gfx Archives|url=https://lists.freedesktop.org/archives/amd-gfx/|access-date=2021-02-01}}</ref> - freedesktop, which isbeing home to major Linux graphics projects such as [[Mesa (computer graphics)|Mesa]], [[libdrm]], [[XOrg|Xorg]], [[Wayland (display server protocol)|Wayland]], provides the hardware infrastructure consisting of dozens of GPUs for Linux-kernel-graphics [[continuous integration]].

==SuportSupport==

AMDgpu officially supports cards built upon [[Graphics Core Next|GCN 1.2]] or higher, including new instruction sets such as [[RDNA (microarchitecture)|RDNA]]1&2, CDNA.
