 GPU Support

+NVTOP supports AMD GPUs using the amdgpu driver through the exposed DRM and sysfs interfaces.

+Support for recent GPUs are regularly mainlined into the linux kernel, so please

+### NVIDIA

 The *NVML library* does not support some of the queries for GPUs coming before the
 Kepler microarchitecture. Anything starting at GeForce 600, GeForce 800M and
 successor should work fine. For more information about supported GPUs please
