Note that it's not possible to shift windows around in response to faults because fault reporting is asynchronous - the entire remaining instruction queue will be executed *before* the exception is actually raised to the kernel.
ah that would limit the usefulness of its application in the kernel ... thanks for the info
That sounds reasonable. However, I suspect that most NOMMU CPUs won't be able to do that. In effect you're creating a third option, I think (MMU, NOMMU, MPU).
sure, but i'm not sure the MPU option would be mutually exclusive with NOMMU ... in the Blackfin case, we'd want both ... -mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
