Sorry for the slow turnaround testing this. This version seems to do better with my quirky system. Summary of /proc/zoneinfo now looks like this: $ ./zoneinfo Node Normal Movable DMA DMA32 0 17090.04 85687.43 14.93 1677.41 1 17949.70 81490.98 2 17911.66 85675.00 3 17936.42 85313.32 which gets close to the mirror numbers reported in early part of boot: [ 0.000000] efi: Memory: 81050M/420096M mirrored memory SUM(Normal) = 70887.82 There are ~8GB of "struct page" allocated from boot time allocator, which covers most of the difference in the values. -Tony -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
