qword - A KISS Unix-like operating system, written in C and Assembly for x86_64.

Features

SMP (multicore) scheduler supporting thread scheduling.
Program loading with minimal userspace.
Fully functional VFS with support for several filesystems.
Support for AHCI/SATA.
ATA disk support.

Build requirements

In order to build qword, make sure to have the following installed:

wget
git
bash
make
meson
ninja
GCC and binutils
nasm
QEMU (to test it)

On Debian and Ubuntu, these packages can be installed with:

sudo apt-get install git build-essential meson nasm qemu-system-x86

On FreeBSD, these packages can be acquired using pkg with:

sudo pkg install git wget bash gcc gmake meson nasm qemu

Building

# Clone repo wherever you like
git clone https://github.com/qword-os/qword.git
cd qword
# Build and install echfs-utils (used to build the root fs image)
cd host/echfs-utils
make
# This will install echfs-utils in /usr/local
sudo make install
# Else specify a PREFIX variable if you want to install it elsewhere
#make PREFIX=<myprefix> install
# Now build the toolchain (this step will take a while)
cd ../toolchain
# You can replace the 4 in -j4 with your number of cores + 1
./make_toolchain.sh -j4
# Go back to the root of the tree
cd ../..
# Build the ports distribution
cd root/src
./makeworld.sh -j4
./makeworld.sh clean
# Now to build qword itself
cd ../..
# You might need to use gmake instead of make here on FreeBSD
make clean && make DEBUG=qemu img && sync

You've now built qword, a flat qword.img disk image has been generated. To run the OS in QEMU, use make run-img. To run it with KVM enabled, use make run-img-kvm.
