AMDgpu is AMD's fully open source unified kernel driver for its GPUs on Linux. It takes the form of an in-tree kernel module. As of 2022, AMDgpu development at AMD is part of ROCm, under the ROCk project.

AMDgpu has been fully upstreamed and new developments continue to do so. AMD Kernel Fusion Driver (KFD) is now integrated in this one kernel module.

As AMDgpu is part of the monolithic linux kernel, it is shipped by most Linux distributions directly. AMDgpu-pro, still distributed by AMD directly, is somewhat reliably more up-to-date compared to that of kernels shipped in regular operating system distributions.


AMDgpu officially supports cards built upon GCN 1.2 or higher (including new instruction sets such as RDNA1-2).
Though as of 2021 support for GCN 1.0/1.1 is incomplete,[2] it can be enabled by a kernel parameter[3][4] and some Linux distributions enabled it by default.[5]
