Philippe Rétornaz a7e30b8d91 [AVR32] Fix random segfault with preemption ... As explained on: http://www.avrfreaks.net/index.php?nameÿphpBB2&fileÿewtopic&tS307 If the current process is preempted before it can copy RAR_SUP and RSR_SUP both register are lost and the process will segfault as soon as it return from the syscall since the return adress will be corrupted. This patch disable IRQ as soon as we enter the syscall path and reenable them when the copy is done. In the interrupt handlers, check if we are interrupting the srrf instruction, if so disable interrupts and return. The interrupt handler will be re-called immediatly when the interrupts are reenabled. After some stressing workload: - find / > /dev/null in loop - top (in ssh) - ping -f avr32 The segfaults are not seen anymore.
