Explain this to me: /* - * Minimum and maximum sizes of the kernel malloc arena in PAGE_SIZE-sized + * Minimum size of the kernel kmem_arena in PAGE_SIZE-sized * logical pages. + * No enforced maximum on sparc64. */ -#define NKMEMPAGES_MIN_DEFAULT ((6 * 1024 * 1024) >> PAGE_SHIFT) -#define NKMEMPAGES_MAX_DEFAULT ((128 * 1024 * 1024) >> PAGE_SHIFT) +#define NKMEMPAGES_MIN_DEFAULT ((64 * 1024 * 1024) >> PAGE_SHIFT) +#define NKMEMPAGES_MAX_UNLIMITED 1 Does this mean a machine needs to allocate a minimum of 64MB for the kernel kmem_arena or it won't boot? What happens if a machine only has 64MB of DRAM? Eduardo
