        if (timer_is_v1()) {
                tsc_info.u.counter_paddr = phys + MX1_2_TCN;
-               tsc_info.counter_vaddr =(unsigned long)(phys + MX1_2_TCN);
+               tsc_info.counter_vaddr = (unsigned long)(timer_base + MX1_2_TCN)
        } else {
                tsc_info.u.counter_paddr = phys + V2_TCN;
                tsc_info.counter_vaddr = (unsigned long)(timer_base + V2_TCN);
