Introducing HelenOS coastline

I am still trying to bring GCC to HelenOS but the truth is that I haven't made a big progress since my last post. However, I promised another script that would simplify the porting even more. I am not 100% sure it simplifies it that much but it makes the whole process much easier to reproduce. Let me introduce the HelenOS coastline.

Towards GCC for HelenOS (3) - libmpfr

In previous posts I described my effort to bring GCC to HelenOS. This post briefly summarizes porting of yet another GCC dependency: MPFR library. It comes a bit late as the progress was already reported on last HelenOS meeting but the meeting report did not contain the actual commands, so here are they.

Towards GCC for HelenOS (2) - libgmp

In my previous post about bringing GCC to HelenOS, no actual GCC dependency was compiled. In this post I will describe porting GNU MP Bignum library (libgmp).

Towards GCC for HelenOS

Compiling GCC to run inside HelenOS is for quite some time on the ToDo list of HelenOS. I decided to give it a try and if you want to follow what I did so far, carry on reading.

Telneting to HelenOS

Not that long ago TCP rewrite was merged into HelenOS mainline branch. As a proof of its functionality, webserver was improved recently. That encouraged me to implement "remote console" offering posibility to run applications on HelenOS remotely over the network...

Two days with HelenOS USB

We decided to have a coding weekend (the last one) due to approaching deadline for our USB project and I can (again) announce some good news.

OHCI, HID parser and more

It has been a while since my last post about USB support for HelenOS. But we have made some progress that I am proud to announce.

Adding HelenOS to existing GRUB

Last week we started testing our USB drivers on real hardware. That involves a lot of quick fixes, followed by burning the CD image (or creating bootable USB disk) and rebooting the computer. Not very comfortable. So I decided to polish my script for adding HelenOS to existing GRUB and make it available for everyone.

Hello from USB keyboard to HelenOS

I am proud to announce that today we were able to control HelenOS with plugged in USB keyboard. Although the abilities of the keyboard and host controller drivers are very limited, it is a huge step forward in our project.

IPC cheatsheet for HelenOS

Sometimes as a last resort when debugging HelenOS you need to use the kernel console. If the problem has something to do with IPC, you will end deciphering the IPC communication with ipc command. If you also do not remember that 1031 means request to VFS for file closing, you might find the following cheat sheet useful.

USB hub driver working

I would love to sing some ode right now because I just found a bug and get a working hub driver, but I am afraid that I would be dressed down by my father because it is half past 1am. So, hence this post to let the euphoria out ;-).

USB for HelenOS

Because I am also member of the team that wants to add support for USB to HelenOS and I have enough of programming, I decided to write few paragraphs about HelenOS/USB project...

Support for NUMA in HelenOS

Because it will be almost 6 months since I started flirting with the idea to base my thesis on HelenOS somehow, it is time to report some progress.
