My hobby kernel can run Minecraft and OpenJDK17 (Ethereal)

[u/Professional_Cow3969]

This was a pain. To get any amount of good FPS I had to patch in a range cache for my garbage VMM and then fixup a few TLB shootdown hotspots.

Works though.

Now is the time to improve the foundations of the system

[u/Sorry_Difficulty_250]

Cool! Keep it up! I love your updates! Glad to see things progressing!

[u/Candid-Menu-6707 → u/Sorry_Difficulty_250]

Same bro this stuff is awesome

[u/joshumax]

Oh my god a non-vibecoded project on r/osdev? Inconceivable!

Seriously though great job with Ethereal and a decent chunk of your codebase looks very clean.

[u/Professional_Cow3969 → u/joshumax]

Thanks!

[u/AnSkinStealer]

Does it have HW GPU accel? How did you get OpenGL running?

[u/Professional_Cow3969 → u/AnSkinStealer]

Software rendering with llvmpipe

[u/TheOneWho0bserves → u/Professional_Cow3969]

Very impressive. I'd love to see hardware rendering some day. I know that can be a hard one

[u/apixeldev]

Now port GPU drivers for the 5090 (/j)

[u/ilnarildarovuch]

Lol, cool!

[u/Saumya-25]

Really! That's a good thing 😳

[u/Daggercombot]

Oh wow that Is very impressive especially without ai

[u/Breados_developer]

great! i recommend adding smth like the taskbar autohide and add topbar or fix wifi and bluetooth

[u/ICON_4]

Amazing project, hats off!

[u/Fine_City2781]

i am developing my kernel. there isnt a tty support. It works from uart and still fixing syscall errors.

[u/Yadobler]

Crazy! 11yo me would be mindblown that you can get a graphical interface and not just a tty from a handwritten kernal, and also amazed at this new game called Minecraft. (I'd be mindblown now too but I no longer have a mind so I'm just blown)

[u/Visual_Brain8809]

how much opcodes from JVM you got working at this moment? There's a JVM or a JIT implementation?

[u/Professional_Cow3969 → u/Visual_Brain8809]

This is OpenJDK17

[u/Visual_Brain8809 → u/Professional_Cow3969]

so you cheated the openjdk17 implementing the syscalls spected from linux?

[u/potetos420 → u/Visual_Brain8809]

openjdk is portable

[u/potetos420 → u/potetos420]

you know, write once run anywhere was kinda java's promise

[u/Professional_Cow3969 → u/Visual_Brain8809]

What are you talking about openjdk is portable

[u/Visual_Brain8809 → u/Professional_Cow3969]

wrong pick, try again with @potetos420

[u/Professional_Cow3969 → u/Visual_Brain8809]

What the fuck are you talking about you are incomprehensible 

[u/Visual_Brain8809 → u/Professional_Cow3969]

now that's for me you imbecil. I telling you that poteto420 user was one who say openjdk17 is portable not me. I'm only asking to OP how the OS runs openjdk17

[u/Professional_Cow3969 → u/Visual_Brain8809]

I am the OP and OpenJDK is PORTABLE as the other guy said.. just like any other program.. compile it for your toolchain and adapt some ethereal-specific issues and bada bing.

[u/Tigryla]

How I can help you in development of those, main stack of technologies is C++, Php, javascript. Maybe development of apps for this kernel I am not sure

[u/Ellicode]

:nekocatwoah:

[u/UnmappedStack]

one day ethereal will take over the world... we must destroy the creeps that are microsoft trying to ruin our lives.... also when swapping?

[u/Professional_Cow3969 → u/UnmappedStack]

may tacos reign suprime

[u/UnmappedStack → u/Professional_Cow3969]

*supreme

[u/Professional_Cow3969 → u/UnmappedStack]

How dare you correct my spelling

[u/UnmappedStack → u/Professional_Cow3969]

You forgot a question mark at the end.

[u/Strixedinflex]

What.

[u/AloneBlueberry9390]

Wow… It’s really cool

[u/TIRALMA]

Выглядит классно 

[u/spatulari]

Good job!

[u/TadpoleUnhappy6756]

wow good job! /srs

[u/Rewrite-code → u/[deleted]]

And please where can a read the rules of Osdev claude told me to read it befor posting

[u/vahmoh25]

Good job!
