  1. I have successfully boot the Embedded Linux of Digilen-linux-Dev according to Embedded_Linux_Hands-on_Tutorial.pdf. Now I want to simulate the DVFS using Linux's CPUFreq framework,so I managed to look up the Frequency Table and OPP list.But I didn't find the folder called "cpufreq" which might be located at "/sys/device/system/cpu/cpu0/cpufreq". Where should I find this folder,because I want to know what frequency/voltage set I can use to vary before I simulate DVFS operation.
  2. I have bought the ZYBO Zynq™-7000 Development Board with "Voucher for Xilinx Vivado® Design Suite: Design Edition ",and there are something I want to make sure before I use this Vivado Voucher.(1)This voucher said that the code of license may only be used once.so if I have generate the license file and used it on my Vivado Design Suite,but I want to reinstall my computer's OS or reinstall the Vivado Design Suite in the future then this license cannot be used again ?(2)This license can only enable use of the Logic Analyzer tools ? How about the others Vivado's software likes Vivado HLS ?
