:candy: All-new engine of the @GreenteaOS

Tofita

All-new engine to-fit-a Greentea OS (hence "Tofita")

Greentea OS is aimed to provide complete operating system compatible with existing apps

GreenteaOS (Tofita) system requirements

• 64-bit UEFI
• Very low on resources, just 2 GB RAM minimum required
• Motherboard with SATA (AHCI) or NVMe, PCIe and USB 2.0+
• Multicore modern 64-bit CPU (most AMD and Intel CPUs from Q3 2011 and newer)
  • Try Greentea OS Compatibility Assistant on your PC

Give some attention for Greentea OS be noticed and attract more contributors, thank you!

Become a sponsor to help us hire developers and test more hardware

Tools

• listen.js - listen to VirtualBox COM port in TCP socket mode
• pipe.js - listen to VirtualBox\Hyper-V COM port in pipe mode
• vbox.js - starts VirtualBox Tofita VM and exits
• webui.bat - web-based UI for COM port
• gos-devlist.bat - show useful device names and PCI IDs to gather user hardware stats
• OVMF.fd - speed of light UEFI bootloader for QEMU
• Greentea OS Compat - Greentea OS compatibility assistant
• build.bat - check comments for examples of how to re-inject .iso file in VirtualBox and avoid full VM reboot for faster testing iterations

Edit Online

You may edit and commit directly from the browser:

https://github.dev/GreenteaOS/Tofita/blob/kawaii/README.md

Remember to open Extensions and install Hexa! Reload the tab if you don't see file icons.

Making a commit in the Source Control panel will create a Fork automatically for you.

Build

Get automatic build or make yours with Teapot (if you want to edit the code)

Teapot is a bundle containing all of the build tools you need like LLVM and NASM.

Automatic builds

If you don't want to build Tofita, you may download the latest automatic GitHub build.

Build using Teapot

Download or clone Teapot repo and others. Place alongside of Tofita repo:

.\Teapot
.\Tofita
.\Greentea
.\Tongue
.\NjRAA

You should have extracted Teapot-kawaii and have folders like this .\Teapot\LLVM-*.*.*.

Teapot will take less space if cloned with limited depth of commit history:

git clone --recursive --depth 1 https://github.com/GreenteaOS/Tofita.git
git clone --recursive --depth 1 https://github.com/GreenteaOS/Teapot.git
git clone --recursive --depth 1 https://github.com/GreenteaOS/Greentea.git
git clone --recursive --depth 1 https://github.com/GreenteaOS/Tongue.git
git clone --recursive --depth 1 https://github.com/GreenteaOS/NjRAA.git

Configure

Add your apps, folders and other files into assets\desktop of the Greentea repo to see them in the built image.

Create R: ram disk about 1 GB (you may download a free AMD Radeon™ RAMDisk) for faster builds and configure config.json > tempFolder. Otherwise C: is used to store builds by default.

Install Hexa

You also need to install Hexa compiler. Simply use the latest graphical installer from the automated builds.

You may build Hexa manually too. Follow instructions. Remember to add Hexa into your PATH.

Compile and generate disk image

cmd /c build

Or just open build.bat file with Explorer.

You'll find Tea subfolder with binaries and disk image.

tofita's Issues

unable to run the nightly build iso file of tofita in vbox

i did all the settings for uefi and 2gb ram and tried testing in virtual box but it didn't gone well ,I got guru meditation screen in vbox..

Use GitHub Actions for builds

Is your feature request related to a Tofita kernel specifically? Please describe

Do it ASAP

Describe the solution you'd like

This should work the same way as AppVeyor does for now

Describe alternatives you've considered

Better GitHub integration

Virtualbox build crashes

Hello,

I wanted to test GreenteaOS and built it according to the instructions as well as to create the Virtualbox (6.1.4) VM according to

(https://github.com/GreenteaOS/Tofita/blob/master/VirtualBox_HOWTO!.txt)

---

Use exactly "Mac OS X (64-bit)" preset (it enables UEFI and other stuff)

Set 2 Gb RAM or more

---

The ISO created and then when I tried to start the VM, I get:

---

A critical error has occurred while running the virtual machine and the machine execution has stopped.

That is as far as it goes.

Any ideas on how to fix this?

Did I miss something in my steps?
Cheers

[FEATURE PROPOSAL] adding linux compiler

so yes, for the now i only saw .bat script, as far i know its a windows executable. will you maybe make a version also for linux/bsd (in bash)? also lacking ,ac support although im not into apple, just saying...

Bad graphics mode (GOP) on some hardware

Describe the bug

Shows malformed animation and crashes

Reproduction

Simply boot from USB

Platform

May happen to be more common than it seems

Expected behavior

No response

Screenshots

Imagine a skewed rectangle or something

Additional context

Probably wrong scanline width (on copy) and/or memory mapping of framebuffer

Run some actual OS tests with QEMU in CI

Is your feature request related to a Tofita kernel specifically? Please describe

We must test a lot of hardware combinations. This is highly achievable with QEMU.

Describe the solution you'd like

Add QEMU to Teapot and run it with Actions. QEMU allows to save log into a file, which we will save as artifact. Also test VM combinations in parallel if possible with same OS image reused

Less annoying regressions

Windows cannot build it!

Hello when i try to compile hexa i always get error in windows i am currently using Windows 10 👍

[?] Can it run on a real machine with out a virtual box?

? Can it run on a real machine No virtual box

Unable to build the tofita, due to error

I just tried to compile the tofita kernel but it shows the error in :-
boot/uefi/boot.c:113:4: error : use of undeclared identifier 'bootsvc'

Screenshots

CI must download Greentea repo

Is your feature request related to a Tofita kernel specifically? Please describe

https://github.com/GreenteaOS/Greentea will be used for user mode assets

Describe the solution you'd like

Simply download alongside of Tofita and Teapot (NOT inside Tofita!)

build fails on Windows

Describe the bug

aside from "error eperm operation not permitted unlink" on init-or-clean, getting to the NASM stage throws a bunch of "file not found" errors, which is pretty confusing.

Reproduction

1. fetch all of the 4 repos
2. go to Tofita
3. run cmd /c build
4. watch the syscall error on init-or-clean
5. if you skip init-or-clean, nasm will throw a bunch of "file not found" errors

Platform

• VMware Workstation 17 virtual machine running Windows 11 x64 on a host machine running Linux on a Ryzen 5 2600
• i fetched the kawaii branch using the git clone commands from the readme

Expected behavior

build is supposed to just fly through the projects
