SMP MIPS and Linux 3.2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


I'm running Linux 3.2 on a MIPS 34K with two VPEs (in MT_SMP configuration). It works fine in UP but with SMP it deadlocks during bootup (both CPUs gets idle). Typically like this:

[    0.090000] CPU revision is: 01019550 (MIPS 34Kc)
[    0.090000] Primary instruction cache 32kB, VIPT, 4-way, linesize 32 bytes.
[    0.090000] Primary data cache 32kB, 4-way, PIPT, no aliases, linesize 32 bytes
[    0.170000] Brought up 2 CPUs
<No more output>

I have tried to enable __ARCH_WANT_INTERRUPTS_ON_CTXSW but that didn't improve anything. Anyone else got this running or have any thoughts about what the problem may be?

Best Regards
