Maximum zone order
configname: CONFIG_FORCE_MAX_ZONEORDER
Linux Kernel Configuration
└─>Memory management options
└─>Maximum zone order
In linux kernel since version 2.6.12
The kernel memory allocator divides physically contiguous memory
blocks into "zones", where each zone is a power of two number of
pages. This option selects the largest power of two that the kernel
keeps in the memory allocator. If you need to allocate very large
blocks of physically contiguous memory, then you may need to
increase this value.
This config option is actually maximum order plus one. For example,
a value of 11 means that the largest free memory block is 2^10 pages.
The page size is not necessarily 4KB. Keep this in mind when
choosing a value for this option.
