ToaruOS v1.99.5

ToaruOS v1.99.5

What's New in v1.99.5?

Several major features, improvements, and bugfixes have been added since the last release:

• Support for filesystem groups and supplementary group lists has been added, along with a groups command.
• A new calculator app has been added, which uses Kuroko as a backend.
• The bootloader now has a simple text editor for modifying kernel command lines.
• The compositor has been rewritten to be single-threaded for better visual stability and performance.
• Several drivers from toaru32 have been ported to Misaka, including the IDE controller driver, PC beeper driver, and the ISO 9660 filesystem implementation.
• Support for automatic display resizing in VMware Player has been restored.
• The libc qsort is now a viable quicksort implementation, which has improved performance significantly in text rendering.
• The use of shared memory mapped font files has been reimplemented, which improves text rendering performance in most applications.
• A fix has been implemented for incorrect handling of page table invalidation, which has resolved a major source of slowdown when running with SMP.

This release also celebrates 5000 commits to the main git branch!

What is ToaruOS?

ToaruOS is a hobbyist, educational operating system for x86-64 PCs, focused primarily on use in virtual machines. It provides a Unix-like environment, complete with a graphical desktop interface, shared libraries, feature-rich terminal emulator, and support for running, GCC, Quake, and several other ports. The core of ToaruOS, provided by the CD images in this release, is built completely from scratch. The bootloader, kernel, drivers, C standard library, and userspace applications are all original software created by the authors, as are the graphical assets.

Who wrote ToaruOS?

ToaruOS is primarily written by a single maintainer, with several contributions from others. A complete list of contributors is available from AUTHORS.

Running ToaruOS

It is recommended that you run ToaruOS in a virtual machine / emulator, for maximum compatibility. ToaruOS's driver support is limited, and running on real "bare metal", while possible, does not provide the most complete experience of the OS's capabilities except on very particular hardware. ToaruOS is regularly tested in VirtualBox, QEMU, and VMWare Player, and can be successfully booted (with poor performance) in Bochs. ToaruOS is intended to run from a live CD, though it is possible to install to a hard disk. Additional details on running ToaruOS in different virtual machines is available from the README.

Release Files

image.iso is the standard build of ToaruOS, built by the Github Actions CI workflow. It uses ToaruOS's native bootloaders and should work in most virtual machines using BIOS.

ToaruOS v1.99.3

ToaruOS v1.99.3

What's New in v1.99.3?

This is an iterative development beta of ToaruOS 2.0. This release includes a number of new major features:

• Loadable kernel modules are supported again and a handful of device drivers have moved back into modules. Unlike in ToaruOS 1.x, modules are not loaded from Multiboot "modules", and instead only loaded from userspace with the insmod tool. In combination with PCI device ID scanning, the system startup scripts will load necessary modules for supported devices when the relevant devices are found.
• A new TrueType text rasterization engine has been implemented, replacing the "signed distance field" text rasterization system used since ToaruOS 1.5. The SDF library has been removed and all applications have been ported to the new TrueType renderer. The implementation is incomplete, but has sufficient support for rendering the DejaVu Sans family, which is included as it was in previous releases.
• The panel has gone through some visual redesign.
• The graphics library now includes support for arbitrary, composable affine transformations of textures.
• The BIOS CD bootloader includes an automatic timeout.

Many other minor improvements and bug fixes have also been made.

Please note that from this point forward, ToaruOS 2.0 beta releases will not be marked as "pre-releases" on Github, in order to have them appear on the front page of the repository.

ToaruOS v1.99.1

ToaruOS v1.99.1

What's New in v1.99.1?

This is a beta release of ToaruOS 2.0.

ToaruOS 2.0 includes a new kernel, Misaka, targeting x86-64 and with support for SMP. The new kernel is still in development, and many features are missing that we hope to include in a final release of ToaruOS 2.0 at a later date. Several hardware drivers have not yet been ported to Misaka. Block device drivers are not yet available, though the final release is planned to include drivers for AHCI devices. Network chipset drivers for Realtek and AMD devices have also not yet been ported; users who wish to experiment with network features should use a supported Intel "e1000" or "e1000e" device (both QEMU virtualized devices have been tested, and general support has been confirmed on at least one real chipset). The network stack is still a work-in-progress and has not reached the same level of functionality as the one provided in early versions of the OS; in ideal conditions, the package manager may be used to install a collection of ports, and the fetch utility may work. SMP support is also still considered experimental, and while some degree of stability can be achieved depending on the workload it is not recommended for any attempt at "daily use". Finally, we are working to build a new EFI bootloader and the release image attached here contains only an updated BIOS loader; GRUB CDs may be provided with future beta iterations.

What's New in v1.14.0?

This release features Kuroko 1.1.0 and fixes issues with the EFI bootloader in VirtualBox. A number of improvements have also been made to the libc, including a new printf implementation and corrections to some floating point mathematics functions which has fixed the lighting in Quake. The CD images have gotten smaller as the ramdisk images are now compressed.

What is ToaruOS?

ToaruOS is a hobbyist, educational operating system for x86 PCs, focused primarily on use in virtual machines. It provides a Unix-like environment, complete with a graphical desktop interface, shared libraries, feature-rich terminal emulator, and support for running Python 3.6, GCC, and several other ports. The core of ToaruOS, provided by the CD images in this release, is built completely from scratch. The bootloader, kernel, drivers, C standard library, and userspace applications are all original software created by the authors, as are the graphical assets.

Who wrote ToaruOS?

ToaruOS is primarily written by a single maintainer, with several contributions from others. A complete list of contributors is available from AUTHORS.

Running ToaruOS

It is recommended that you run ToaruOS in a virtual machine / emulator, for maximum compatibility. ToaruOS's driver support is limited, and running on real "bare metal", while possible, does not provide the most complete experience of the OS's capabilities except on very particular hardware. ToaruOS is regularly tested in VirtualBox, QEMU, and VMWare Player, and can be successfully booted (with poor performance) in Bochs. ToaruOS is intended to run from a live CD, though it is possible to install to a hard disk. Additional details on running ToaruOS in different virtual machines is available from the README.

Release Files

image.iso is the standard build of ToaruOS, built the Github Actions CI workflow. It uses ToaruOS's native bootloaders and should work in most virtual machines using either BIOS or EFI boot.

When provided in a release, toaruos-grub.iso is an alternative CD with GRUB as a bootloader. If you are attempting to run ToaruOS on real hardware, this is generally preferred.

Known Issues

• Several utilities are missing functionality.
• The libc's implementation of scanf is incredibly incomplete.
• There are many known security issues with ToaruOS. You should not use ToaruOS in a production environment - it is a hobby project, not a production operating system. If you find security issues in ToaruOS and would like to responsibly report them, please file a regular issue report here on GitHub.
• There appears to be a problem with the performance of the gzip decompression implementation in the BIOS loader under TCG in QEMU. Users are recommended to use an accelerated backend or boot with EFI.
