Message-ID: <3E638522.3080008@walrond.org> (raw)
The dump looks like this:
BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 00000000000a0000 (usable)
BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved)
BIOS-e820: 0000000000100000 - 00000000bfffa000 (usable)
BIOS-e820: 00000000bfffa000 - 00000000bffff000 (ACPI data)
BIOS-e820: 00000000bffff000 - 00000000c0000000 (ACPI NVS)
BIOS-e820: 00000000fec00000 - 00000000fec01000 (reserved)
BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved)
BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved)
BIOS-e820: 0000000100000000 - 0000000140000000 (usable)
Warning only 4GB will be used.
Use a PAE enabled kernel.
3200MB HIGHMEM available.
896MB LOWMEM available.
So you are saying that not all the 4Gb of ram will get mapped/used
(specifically, everything not marked 'usable') ?
Can you quantify the performance degredation of a PAE enabled kernel?
