I am contemplating using the DEVICE_POLLING kernel option with an fxp NIC on FreeBSD 5.3 using an SMP kernel.
/usr/src/sys/kern/kern_poll.c clearly states that DEVICE_POLLING is incompatible with SNP kernels: #ifdef SMP #ifndef COMPILING_LINT #error DEVICE_POLLING is not compatible with SMP #endif #endif Yet there are various performance tuning FAQs floating around the Net stating that DEVICE_POLLING will work just fine with SMP kernels and that the user can safely delete the above section from kern_poll.c This may well be the case, but if this is true, why wouldn't that section have been removed from kern_poll.c by now? What are the corner cases, if any, that an admin should be aware of that keep this error message in the code?
