This is an offtopic question. What determines the amount of 'reserved' memory, and how much to reserve?
With 2.4.1-ac3, I came up with the following different memory readings for both a Pentium 166 and an Athlon 750.
Pentium 166: (96MB RAM) ------------ BIOS-provided physical RAM map: BIOS-e820: 000000000009fc00 @ 0000000000000000 (usable) BIOS-e820: 0000000000000400 @ 000000000009fc00 (usable) BIOS-e820: 0000000000010000 @ 00000000000f0000 (reserved) BIOS-e820: 0000000005f00000 @ 0000000000100000 (usable) BIOS-e820: 0000000000010000 @ 00000000ffff0000 (reserved) On node 0 totalpages: 24576 zone(0): 4096 pages. zone(1): 20480 pages. zone(2): 0 pages. Memory: 94732k/98304k available (890k kernel code, 3184k reserved, 261k data, 176k init, 0k highmem)
Athlon 750: (128MB RAM) ----------- BIOS-provided physical RAM map: BIOS-e820: 000000000009fc00 @ 0000000000000000 (usable) BIOS-e820: 0000000000000400 @ 000000000009fc00 (reserved) BIOS-e820: 0000000000010000 @ 00000000000f0000 (reserved) BIOS-e820: 0000000000010000 @ 00000000ffff0000 (reserved) BIOS-e820: 0000000007f00000 @ 0000000000100000 (usable) On node 0 totalpages: 32768 zone(0): 4096 pages. zone(1): 28672 pages. zone(2): 0 pages. Memory: 126500k/131072k available (1127k kernel code, 4184k reserved, 322k data, 200k init, 0k highmem)
Last year, when I had 32MB of memory in the Pentium 166 machine, the amount of 'reserved' memory seemed lower. It almost looked as if the amount of reserved memory is a fraction of total available memory.
Is there a way I can 'regain' this memory from the system, especially in cases when there's only 32MB to work with?
Thanks, Byron
