Linux Drivers This page is intended to give more details on the Xilinx drivers for Linux, such as testing, how to use the drivers, known issues, etc. The drivers included in the kernel tree are intended to run on the ARM (Zynq, Ultrascale+ MPSoC, Versal) and MicroBlaze Linux. Driver InformationThere are a number of drivers in the kernel tree due to history and they may work, but the following list of drivers are currently what's tested and users are encouraged to use these rather than others. Any other drivers, not in the mainline and only in the Xilinx tree, may be old and that they could be removed at any time.
