It certainly works for all the targets I'm looking at right now. In those cases the boot protocol couldn't care less about the IPI number as the point is only to kick the target CPU out of WFI. And that message certainly has to go as it may be triggered multiple times per second in some use cases here.Last time this came up I thought we covered most of the platforms? OMAP, Realview, Versatile Express, and MSM are covered by this thread http://lists.infradead.org/pipermail/linux-arm-kernel/2011-January/039275.htmlOk, in that case I've just committed three patches to make those platforms use SGI0 instead of SGI1.
Great. Kukjin Kim, can exynos use SGI0? It looks like exynos is the only one left to move to SGI0. -- Sent by an employee of the Qualcomm Innovation Center, Inc. The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum.
