1652 | This option inform the kernel to use Hot Pluggable bit | ||
1653 | in flags from SRAT from ACPI BIOS to determine which | ||
1654 | memory devices could be hotplugged. The corresponding | ||
1655 | memory ranges will be set as ZONE_MOVABLE. | ||
1656 | NOTE: Whatever node the kernel resides in will always | ||
1657 | be un-hotpluggable. | ||

1659 | movablemem_map=nn[KMG]@ss[KMG] | ||
1660 | [KNL,X86,IA-64,PPC] This parameter is similar to | ||
1661 | memmap except it specifies the memory map of | ||
1662 | ZONE_MOVABLE. | ||
1663 | If user specifies memory ranges, the info in SRAT will | ||
1664 | be ingored. And it works like the following: | ||
1665 | - If more ranges are all within one node, then from | ||
1666 | lowest ss to the end of the node will be ZONE_MOVABLE. | ||
1667 | - If a range is within a node, then from ss to the end | ||
1668 | of the node will be ZONE_MOVABLE. | ||
1669 | - If a range covers two or more nodes, then from ss to | ||
1670 | the end of the 1st node will be ZONE_MOVABLE, and all | ||
1671 | the rest nodes will only have ZONE_MOVABLE. | ||
1672 | If memmap is specified at the same time, the | ||
1673 | movablemem_map will be limited within the memmap | ||
1674 | areas. If kernelcore or movablecore is also specified, | ||
1675 | movablemem_map will have higher priority to be | ||
1676 | satisfied. So the administrator should be careful that | ||
1677 | the amount of movablemem_map areas are not too large. | ||
1678 | Otherwise kernel won't have enough memory to start. | ||
1679 | NOTE: We don't stop users specifying the node the | ||
1680 | kernel resides in as hotpluggable so that this | ||
1681 | option can be used as a workaround of firmware | ||
1682 | bugs. | ||
