Hi, I have a P2020 CPU (powerpc) and I compiled it with two different defconfigs. The first one is a SMP, 2 cores, launched with the "nosmp" kernel parameter, the other one is an UP kernel.
My driver behaviour is not the same whether launching one or the other. It is hard to explain more precisely, as it deals only with ioctl which only does ioread32/iowrite32 on a PCIe device. But I can tell that it never works the same way when UP (not working correctly), or SMP "nosmp" (working) or even SMP (not working). AFAIK, the "nosmp" parameter should tell the kernel to act the same is if it is an UP kernel, and it disables IO APIC, which is not an issue in my case. Can you think about anything that would explain it, or would help me debugging it ? Thanks in advance for your help.
