config UIO_XILINX_APM tristate "Xilinx AXI Performance Monitor driver" depends on MICROBLAZE || ARCH_ZYNQ || ARCH_ZYNQMP help This driver is developed for AXI Performance Monitor IP, designed to monitor AXI4 traffic for performance analysis of AXI bus in the system. Driver maps HW registers and parameters to userspace. To compile this driver as a module, choose M here; the module will be called uio_xilinx_apm. |
