Firmware Test Suite - memmapdump utility
This utility dumps the system memory map. This information is simply derived from /sys/firmware/memmap which in turn has gathered this data at boot time using the Int 0x15 AX=0xe820 on a traditional BIOS or via the memory map protocol boot service on a UEFI system.
Example output is as follows:
00013 memmapdump Dump system memory map. 00014 memmapdump ------------------------------------------------------------------ 00015 memmapdump Test 1 of 1: Dump system memory map. 00016 memmapdump Memory Map Layout 00017 memmapdump ----------------- 00018 memmapdump 0000000000000000 - 000000000009f7ff (System RAM) 00019 memmapdump 000000000009f800 - 000000000009ffff (reserved) 00020 memmapdump 00000000000d2000 - 00000000000d3fff (reserved) 00021 memmapdump 00000000000dc000 - 00000000000fffff (reserved) 00022 memmapdump 0000000000100000 - 00000000bf6cffff (System RAM) 00023 memmapdump 00000000bf6d0000 - 00000000bf6e2fff (ACPI Non-volatile Storage) 00024 memmapdump 00000000bf6e3000 - 00000000bfffffff (reserved) 00025 memmapdump 00000000e0000000 - 00000000efffffff (reserved) 00026 memmapdump 00000000fec00000 - 00000000fec0ffff (reserved) 00027 memmapdump 00000000fed00000 - 00000000fed003ff (reserved) 00028 memmapdump 00000000fed14000 - 00000000fed19fff (reserved) 00029 memmapdump 00000000fed1c000 - 00000000fed8ffff (reserved) 00030 memmapdump 00000000fee00000 - 00000000fee00fff (reserved) 00031 memmapdump 00000000ff000000 - 00000000ffffffff (reserved) 00032 memmapdump
Example:
sudo fwts memmapdump -
..runs the memmapdump on your machine and dumps the output to stdout.
