I tried recompiling the kernel on a 5.3-beta2 box with DEVICE_POLLING enabled. Compilation failed with a message saying DEVICE_POLLING isn't compatible with SMP.
Luigi says on: http://info.iet.unipi.it/~luigi/polling/ "Why does this code not work with SMP ? It actually might work (if you remove a one line in systm.h which prevents compilation with SMP). However, you would have a single thread doing the polling, whereas an SMP box might in principle handle concurrently interrupts from different devices. I guess the best answer is that I am not yet sure on whether or not it makes sense to have polling with SMP. " The box in question is a "pseudo SMP" system, with an Intel HyperThreaded P4 and with the fxp onboard the D850MV motherboard. Has anyone hacked systm.h as per above and enabled DEVICE_POLLING on an HT system? If so, did things compile and generally, work? -- Juha _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
