Russell King want people to move to SGI0 for this, so that we can have SGI1-N as the proper IPIs, but now we can't do this, maybe we must wait for so many years. But, Do you think we can use a another way to resolve this problem, because this warning message will oftenly appeare in products. We can't assume the fixed IPI number that can wakeup secondary cores. "I'd much rather see platforms deciding whether they need to use SGI1 or whether they can switch to SGI0 instead."Why not just fix your platform to use SGI0. I think we're _finally_ there with everyone using SGI0, which means we can commit the patch which fixes this.
Yes. I'm going to put it in the patch tracker now. https://patchwork.kernel.org/patch/1433931/ -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
