VM_KMEM_SIZE_SCALE specifies which fraction of the available physical memory, after deduction of the kernel itself and other early statically allocated memory, can be used for the kmem_map. The kmem_map provides for all UMA/malloc allocations in KVM space. Previously ARM was using a fixed kmem_map size of (12*1024*1024) = 12MB without regard to effectively available memory. This is too small for recent ARM SoC with more than 128MB of RAM. For reference a description of others related kmem_map parameters: VM_KMEM_SIZE default start size of kmem_map if SCALE is not defined VM_KMEM_SIZE_MIN hard floor on the kmem_map size VM_KMEM_SIZE_MAX hard ceiling on the kmem_map size VM_KMEM_SIZE_SCALE fraction of the available real memory to be used for the kmem_map, limited by the MIN and MAX parameters.
