These changes enable onlining memory into ZONE_MOVABLE on power, and the creation of discrete nodes of movable memory. We provide a way to describe the extents and numa associativity of such a node in the device tree, yet still defer the memory addition to take place post-boot through hotplug. In v1, this patchset introduced a new dt compatible id to explicitly create a memoryless node at boot. Here, things have been simplified to be applicable regardless of the status of node hotplug on power. We still intend to enable hotadding a pgdat, but that's now untangled as a separate topic. v2: * Use the "status" property of standard dt memory nodes instead of introducing a new "ibm,hotplug-aperture" compatible id. * Remove the patch which explicitly creates a memoryless node. This set no longer has any bearing on whether the pgdat is created at boot or at the time of memory addition. v1: * http://lkml.kernel.org/r/1470680843-28702-1-git-send-email-arbab@xxxxxxxxxxxxxxxxxx Reza Arbab (3): drivers/of: recognize status property of dt memory nodes powerpc/mm: allow memory hotplug into a memoryless node mm: enable CONFIG_MOVABLE_NODE on powerpc Documentation/kernel-parameters.txt | 2 +- arch/powerpc/mm/numa.c | 13 +------------ drivers/of/fdt.c | 8 ++++++++ mm/Kconfig | 2 +- 4 files changed, 11 insertions(+), 14 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
