I have no ideas halp
2021-05-08Better cmdline parsingMarvin Borner
2021-05-08Better serial managementMarvin Borner
Yay, I wrote my final information technology exam yesterday (abitur). Only english and mathematics are left now - hype!! (sorry for polluting my commit messages with useless personal news but this will affect the future of Melvix as my free time and therefore the time that I'm working on this project will increase massively once I'm finished with all my exams)
2021-05-05Debugging improvementsMarvin Borner
STILL NOT FOUND (see previous descr)
2021-05-04General fixes (see description) - closes #17Marvin Borner
Somehow the Grub conversion (or anything before/between that) seems to have caused a *very* weird memory bug involving the heap/stack/sth overflowing into the video memory which will obviously result in strange undefined behaviour when data is written to the video memory. VERY STRANGE. Well, I need to prepare for my finals (Abitur) so I don't know whether I can fix this issue in the next few days. We'll see...
2021-05-03Fixed TSSMarvin Borner
2021-05-03PUREMarvin Borner
2021-05-02Some GDT improvements (attempts to fix no I/O GPF)Marvin Borner
2021-04-30Some small fixes here and thereMarvin Borner

2021-04-29Alright!Marvin Borner
2021-04-29Multiboot/Grub progressMarvin Borner
2021-04-28Started conversion to Grub (#17)Marvin Borner
Yes, the CI won't like this.
2021-04-27Huge compositor, timer and yielding improvementsMarvin Borner
2021-04-26PS/2 mouse aahMarvin Borner
2021-04-26Added VMMouse support and improved PS/2 mouseMarvin Borner
2021-04-25Added range-based memory validatorMarvin Borner
2021-04-25Chu chuu, using the bus for everything now!Marvin Borner
Well, I know: bus != train. But I like trains. So I don't care. Go away!
2021-04-17Added I/O bus implementation for efficient IPCMarvin Borner
This was a nice coding session. See ya tomorrow!
2021-04-17Implemented I/O pollingMarvin Borner
2021-04-16New elegant I/O blocking solutionMarvin Borner
This is done using an internal scheduler syscall (127). Very nice!
2021-04-15Basic block/unblockMarvin Borner
2021-04-14Implemented some I/O interfacesMarvin Borner
2021-04-14Even more I/O - started new PS/2 driverMarvin Borner
2021-04-13Started IO dev managerMarvin Borner
2021-04-10Some changes here and thereMarvin Borner
2021-04-10Gave procs own kernel stack (TSS)Marvin Borner
2021-04-09Added readable/writable checksMarvin Borner
2021-04-08Added UMIPMarvin Borner
2021-04-08Renamed ext2 functionsMarvin Borner
2021-04-06Made exec syscall relative using app nameMarvin Borner
My plan is to implement a mobile-OS-like sandboxing using manifests and permission middlewares. Let's see if I can manage to do this without sacrificing too much performance. I'm also wondering whether I should implement open/close syscalls which would result in a cleaner block/unblock mechanism. I need to think. Hmmm.. Naa

By using the nonnull attribute and replace buffer-overflow-prone functions like strcpy, strcat and sprintf by strlcpy, strlcat and snprintf.
2021-03-28Added ring0 privileges to kernel processesMarvin Borner
This enables a more efficient idling process using the hlt instruction. The context-switching is a bit slower now, too. I have to look into that.
2021-03-26Renamed libsMarvin Borner
Cleaner and more flexible.
2021-03-24Huge GUI improvementsMarvin Borner
2021-03-21Cleaner shared memory implementationMarvin Borner
