Hi Gilles：
            I have a proble with  Intel(R) Atom(TM) CPU  E3827  @ 1.74GHz . We have fpga on pcie and fpga give  250us interrupt signal to our task . The  interrupt type is   MSI  .The proble is when we start gpu test glxgears the task  latency just 15us when we start without glxgears the latency is about 120us  . We tested a week‘s  time always the same situation. We don’t know why？ Thanks！！！
