1959 | help | |
1960 | The kernel memory allocator divides physically contiguous memory | |
1961 | blocks into "zones", where each zone is a power of two number of | |
1962 | pages. This option selects the largest power of two that the kernel | |
1963 | keeps in the memory allocator. If you need to allocate very large | |
1964 | blocks of physically contiguous memory, then you may need to | |
1965 | increase this value. | |
1966 | ||
1967 | This config option is actually maximum order plus one. For example, | |
1968 | a value of 11 means that the largest free memory block is 2^10 pages. | |
1969 | ||
1970 | The page size is not necessarily 4KB. Keep this in mind | |
1971 | when choosing a value for this option. | |
