@ -121,59 +121,6 @@ We *actually* recommend 100GB, because Libreboot will also have a Linux distro
in flash on a future release. On our testing, disk I/O does not seem to be a
major bottleneck, so any HDD or SSD will do, but we obviously recommend a
fast NVMe (PCI-E) SSD if you can.
ystem requirements
===================
This concerns system requirements when *building* Libreboot.
Operating system
----------------
Any sensible Linux distribution will do. Libreboot's build system is regularly
testing on all the major distros. Please do report bugs if you encounter
issues.
Host CPU
--------
At least an Intel Core 2 Duo, though we recommend much faster CPUs if building
entire release archives, e.g. quad-core Haswell CPU or better.
NOTE: x86 boards require an *x86_64* host CPU with appropriate host toolchains
and libraries. We don't yet cross-compile x86 payloads.
NOTE2: ARM64 mainboards *are* cross compiled, so you can build for AArch64
machines quite easily, from x86 or ARM64 machines.
NOTE3: *32-bit* x86 (i686) machines can be used to compile Libreboot, but
MemTest86\+ is only compiled for 64-bit, and not cross compiled, so builds
are disabled when lbmk detects a 32-bit host CPU.
Memory
------
At least 2GB per CPU core, ideally 4GB; for example, 16GB RAM is recommended
if you're compiling an a quad-core CPU.
NOTE: `XBMK_THREADS` environmental variable defaults to 1 if unset. This sets
the number of build threads, which you should match to the number of cores.
For example, when you're building on a quad-core, do this prior to building:
export XBMK_THREADS=4
Disk space
----------
About 20GB bare minimum, if only compiling for 1 board. The sources take up a
lot of space. However, Libreboot is always expanding as it's developed.
At least 50GB of free disk space is therefor recommended.
We *actually* recommend 100GB, because Libreboot will also have a Linux distro
in flash on a future release. On our testing, disk I/O does not seem to be a
major bottleneck, so any HDD or SSD will do, but we obviously recommend a
