Testing my log function and kernel halt (with message)

Windows oriented all the same way are boring.

This shows various programs running at once in 16 colors.

Dear god man, write a BGA driver and get some sweet, sweet 32bpp going.

I didn't even know 800x600x4bpp was even a thing.

Actually, the default driver supports 32BPP already through VBE. I also have a BGA driver which used to work fine, but it stopped working properly in Bochs version 2.6 (the window shrinks to 720x400 and is filled with junk when I enter the debugger in Bochs).

Looks like you are assuming something in your driver that isn't guaranteed to be always the same like memory locations or vídeo mode codes or something like that. For that reason something may break because of using diferent Bochs version or another emulator or machine.

It's called headache mode. It's available on every VGA

It's been a while (years, in fact), so here's a Pedigree screenie I took just now - shared object modules in Python working just fine (in 2.6 and 2.7).

I'm very impressed with ToAruOs and it's successor PonyOS, so I wrote an operating system, ported SDL and Bochs to it, and then ran ToAruOs under my OS with bochs:



Yep, that's my operating system emulating another hobby operating system! :v

@sortie: Nice.

@sortie, wow!

We had a race on #osdev (between sorite, pcmattman, gerryg and myself) - first to port glxgears.



I won.

Built Mesa 7.5.2 (which is particularly old) with just osmesa (software rasterization to a raw buffer) and pointed it at the backbuffer for a window.

Here's a video.

Looks like I made it to the second place.



You can view it in action on youtube as well.


Oh, and as a special bonus, I also ported git.

Well, in my opinion, týndur should be awarded first place, since it features a gears port since September 14 2011.


Also, a YouTube version – which seems to be badly resized (which I blame YouTube for) and in which our (self-written) software rasterizer runs pretty slowly (which is mainly because týndur uses a pretty exotic way of implementing VM86 which in turn requires a bit of luck to get working with KVM; I didn't have that luck today, so this is non-KVM mode).

XanClic: Neat, sounds like you beat us to it - though you didn't participate in the race. Are you using Mesa or a custom software renderer? I saw some x's in the filenames, do you have an X port or is that your own stuff going on?
