From: Vanshidhar Konda <redacted> Increase the default value of NR_CPUS to 512 from 256. This will enable the defconfig kernel to support platforms that have upto 512 cores.Do we already support such a platform, and what is it? I'm fine with bumping. the number, it's just nice to be able to say specifically _why_ we're dong it.I'm not aware of any publicly available systems that run into the 256 core limitation. At Ampere we have internal systems that would benefit from this change as they support more than 256 cores.
But what does that have to do with the default value? Do you expect to run defconfig kernels? I don't ever expect that. -- ~Randy _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
