AMDgpuis anopen sourcedevice driverfor theLinuxoperating system developed byAMDto support itsRadeonlineup ofgraphics cards(GPUs). It was announced in 2014 as the successor to the previousradeondevice driver as part of AMD's new "unified" driver strategy,[3]and was released on April 20, 2015.[4]

Development
editIt takes the form of an in-treekernel module.
As of 2022, AMD Kernel Fusion Driver (KFD) is now integrated in this one kernel module. AMD KFD development at AMD is part ofROCm,under the ROCk project.
Distribution
editAMDgpu has been fully upstreamed and new developments continue to do so.
As AMDgpu is part of themonolithicLinux kernel, it is shipped by most Linux distributions directly. The package suite / install script amdgpu-pro, distributed by AMD directly fromAMD Radeon Software,ships an AMDgpu kernel module somewhat reliably more up-to-date compared to that of kernels shipped in regular operating system distributions.
Community
editThe development of the kernel module happens between AMD and the Linux maintainers, discussions happen on thefreedesktop.orgmailing lists[5][6]- freedesktop being home to major Linux graphics projects such asMesa,libdrm,Xorg,Wayland.
Support
editAMDgpu officially supports cards built uponGCN 1.2or higher, including new instruction sets such asRDNA1&2, CDNA.
Support issues
editThough as of 2022[update]support for GCN 1.0/1.1 is incomplete,[7]it can be enabled by a kernel parameter[8][9]and someLinux distributionsenabled it by default.[10]
