SMVP Support on MIPS34KC (linux-2.6.35)
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi, we are using mips34Kc processor & are facing some issues while enabling SMVP (2 VPEs with 1 TC attached to each VPE) support on the same. We are using linux-2.6.35 kernel downloaded from malta repository. The issue is seen during system boot-up with the control looping in the function stop_machine_cpu_stop. The CPU freezes after the message "Switching to clocksource" . On further debugging, we observed that the function stop_machine_cpu_stop (defined in kernel/stop_machine.c) loops continuously in the 'do while' loop with the condition 'if (smdata->state != curstate)' never matching. The value of curstate is '1' even after we try to re-initialize to 0. What could be going wrong here? We use External timer interrupt as clocksource. One timer interrupt routed on to vpe0 & another timer interrupt routed on to vpe1.
