<p>This week I was working on ocpu emulator. So using it we can know if specifications can be implemented.
|
|
It helps me adding some description to it.</p>
|
|
|
|
<p>First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator
|
|
based on template (that should be placed in docs one day). Now if someone would like to add some architecture to
|
|
our emulator they won’t need to rewrite it from scratch.</p>
|
|
|
|
<p>I also added –system flag to yemu so architecture can be choosen more user-friendly way.</p>
|
|
|
|
<p>Currently in ocpu emulator only mov and add instructions are implemented.
|
|
We also added some description to commands in specifications, so it is easier to understand what it should do</p>
|
|
|
|
<p>Hope you liked this post! If you would like to help me, contact me via email, xmpp or irc :)</p>

<p>This week was very busy week at school and I had no time for programming.</p>
|
|
|
|
<p>But in the start of week I was thinking about making ocpu specs more Turing-complete.
|
|
I still think it is not done but maybe it will in some time (and of course more description required).</p>
|
|
|
|
<p>But I had time to buy some transistors and other electronics. Currently I am trying to make half-adder.</p>
|
|
|
|
<p>I have created tiny log page - <a href="https://g1n.ttm.sh/lolcpu/">lolcpu</a>. I am going to post there some of my
|
|
electronic ideas, circuits and progress in doing some electronic things.</p>

<p>This week I have done several new instructions for yemu. For example all transfer instructions.</p>
|
|
|
|
<p>Also I have rewritten gasm to support 6502, published it and it should help me with debugging yemu.
|
|
It supports not very a lot instructions but I hope it is good start.</p>
|
|
|
|
<p>But I think the coolest what I did this week is ocpu proccessor specification.
|
|
Currently it is draft but i have already published it <a href="https://g1n.ttm.sh/gru/ocpu">here</a>.
|
|
I hope this specifications will be Turing complete and we will try to implement it in real world.
|
|
But firstly we need to make this specififcations complete, assembler and emulator for it.</p>
|
|
|
|
<p>Also smlckz’s idea was to make translator from ocpu assembler instructions to avr to emulate it on arduino!</p>

<p>I am making this devlog a bit earlier, because I will be busy on weekends.</p>
|
|
|
|
<p>This week I didn’t have plan, but it seems I have done some things to yemu: added loading programs
|
|
from binary file and several instructions - TAX, TAY and NOP.</p>
|
|
|
|
<p>I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in
|
|
testing yemu.</p>
|
|
|
|
<p>I was trying to make some daily notes in Org Roam (and moved devlog notes there), but it wasn’t
|
|
very success, but I hope to do it more often :)</p>

<p>Hooray! Today is 10’s GRU Devlog! :)</p>
|
|
|
|
<p>This week i was trying to make notes to org document, to not forget something and put TODOs
|
|
there for future weeks.</p>
|
|
|
|
<p>First several days was the most valuable - readline support and signal handling!
|
|
This means you can use emacs-like bindings there (but i think readline also supports vi bindings,
|
|
so maybe i will add them too!)</p>
|
|
|
|
<p>Also we now have very minimal completion support there :), but still proper function need to be added
|
|
for that (currently only filenames completion)</p>
|
|
|
|
<p>Orsh also has one session history, so you don’t need to rewrite command from scratch now</p>
|
|
|
|
<p>And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash
|
|
and i can exit from there any time i will need)</p>
|
|
|
|
<p>Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.</p>
|
|
|
|
<p>This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) )
|
|
If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!</p>
|
|
|
|
<p>Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining.
|
|
We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.</p>
|
|
|
|
<p>Hope you liked this post and you will join our XMPP muc (if you are not already there) :).

<p>This week I didn’t commited a lot, but started some new projects.
|
|
I made orsh signal handling working (so it won’t exit on ^C) and homedir “handling”
|
|
(can replace homedir in prompt with ~, and you can use ‘cd ~’ or just ‘cd’ to change
|
|
dir to homedir)</p>
|
|
|
|
<p>Also I started making bootloader, but for now it can only detect what CPU is (intel if x86 and amd if x86_64),
|
|
some additional instructions (msr) and if apic is avalible.</p>
|
|
|
|
<p>I was trying to make something with orion fs, maybe it will use pak files for initrd. Currently i am making archiver
|
|
for it, but after that i will need to understand more how vfs working and rewrite initrd to use pak files.</p>
|
|
|
|
<p>We now have xmpp room (gru@conference.hmm.st) and logo! Thanks to chunk for it!</p>
|
|
|
|
<p>I was thinking about making weekly or monthly “conferences”. We could do it via jitsi tildeverse instance or tilde.tel
|
|
(tel.tilde.org.nz) conference. I think jitsi is better, but we should try tilde.tel confernce at least once, why not? :)</p>

<p>This week I have published initrd, but it is not working as expected.</p>
|
|
|
|
<p>Also I have started one more project - orsh. It is one more shell, but now in C.
|
|
Maybe it will be easier to port to Orion. It already supports ; but they are working a bit weird.</p>
|
|
|
|
<p>Also in orsh you can work with environment variables.
|
|
From today’s morning I am trying to replace bash with it, but still a lot need to be done.</p>

<p>This week I was improving Orion. First I made keyboard working, next day paging!
|
|
Also I have added several new LibC functions.
|
|
Today I have made scrolling working.</p>
|
|
|
|
<p>Last few days I was trying to make initrd working
|
|
(this required heap implementing so I also did that but I don’t know if it works correctly).
|
|
Currently it can only output /dev directory.</p>
|
|
|
|
<p>But I made something wrong with %x in printf and it can display weird chars first
|
|
and then contents of files!</p>

<p>This week I had a lot of new ideas. But I think we have to work on something that

have already been started.
|

Also we now have one more coreutils rewrite
|
|
(now on C to more easily port it to Orion in future).</p>
|

<p>Also i have started working on some

|
projects that is not ready to be published yet. One of them is gxt - tui text editor.</p>
|

|
|
<p>Currently it can only move cursor and display files. But I think I’ll publish it next week
|
|
when editing will be working.</p>
|
|
|
|
<p>Bad news is that my school lessons will start next week so maybe this devlogs won’t be

published every week, because of not enough work done. But I don’t know, maybe I’ll have

enough time.</p>

<p>This week I was trying to make interrupts, paging and other memory things working in Orion.
|
|
I found this guide and tried to follow it without rewriting the whole project:
|
|
<a href="http://www.jamesmolloy.co.uk/index.html">http://www.jamesmolloy.co.uk/index.html</a></p>
|
|
|
|
<p>For now only Global Descriptor Table maybe working.</p>
|
|
|
|
<p>My current goals/dreams:</p>
|
|
|
|
<ul>
|
|
<li><p>make filesystem (the coolest would be make Ext2 driver)</p></li>
|
|
<li><p>build GCC hosted compiler (this will help GCC understand our OS better)</p></li>
|
|
</ul>
|
|
|
|
|
|
<p>My very future dreams:</p>
|
|
|
|
<ul>
|
|
<li><p>make kernel, libs, ports and soft in different repos</p></li>
|
|
<li><p>make proper way to make “distros” on our kernel</p></li>
|
|
<li><p>make some website with mirror of ports scripts (like in Serenity OS but not in one repo with
|
|
everything and tool for searching and downloading ports from that mirror)</p></li>
|
|
<li><p>maybe (if i will work a lot on this projects) I’ll make one more account on tilde.team
|
|
for our organisation (domain name - gru.ttm.sh, is cool), but i’ll ask admins about that</p></li>
|
|
</ul>
|
|
|
|
|
|
<p>Also I think Orion need new name because i found several projects with this name :)</p>
|
|
|
|
<p>Some ideas about the GRU name:</p>
|
|
|
|
<ul>
|
|
<li><p>GRU rocks (or rocking) UNIX</p></li>
|
|
<li><p>GloRious UNIX</p></li>
|
|
<li><p>GloRious Union</p></li>

<p>This week I was developing new OS - Orion.</p>
|
|
|
|
<p>I don’t understand very basic osdev thing so I decided to make OS on C and Asm.
|
|
Currently that can just output text (with printf arguments) on screen and serial.
|
|
Now gros is much cooler than Orion - it has input, interupts and a lot of else.
|
|
But maybe I’ll understand OSdev better.
|
|
Currently working on GDT (global descriptor table) and than will work on
|
|
interrupts and exceptions.</p>
|
|
|
|
<p>Of course if you can help me contact me throught email or in other ways!</p>

<p>I didn’t make a lot work this week, so i think this devlogs should be renamed from “week number” to just “number”
|
|
Ok, so what i did this week:
|
|
- Add wc to grutils
|
|
- Published gros
|
|
- Add basic shell and some commands for gros</p>
|
|
|
|
<p>I know that is not a lot, but i was reading some osdev articles and books.
|
|
Currently I would like to implement basic filesystem but i don’t know what to do.</p>
|
|
|
|
<p>Some goals for gros (I will add that to gros readme):
|
|
- Filesystem (FAT or Ext2)
|
|
- ELF or other executable formats
|
|
- LibC (for compiling C programs)
|
|
- Maybe basic networking but after all of that</p>
|
|
|
|
<p>All code in osdev wiki is for C so I need to implement it myself (or port existing rust code)</p>
|
|
|
|
<p>If you can help me somehow please contact me via email (g1n@ttm.sh) or in other ways (~chat irc, xmpp)</p>

<p>So I have started new project this week - grsh! It is shell written on Rust. Also, for now, other rewrites of coreutils are there.</p>
|
|
|
|
<p>What grsh can do for this moment: echo some variables (pwd, user, home, status of previous command using $?) and text; true, false, : - set status; pwd shows current dir, also comments and cd working, basic piping (thanks to <a href="https://www.joshmcguigan.com/blog/build-your-own-shell-rust/">that article</a> and of course executing not builtin command also working.</p>
|
|
|
|
<p>Some grutils that I made: ls, touch, mkdir/rmdir, rm, grep, head/tail, yes, cat.</p>
|
|
|
|
<p>TODOs exist in grsh repo - so you can read there some of my plans.</p>
|
|
|
|
<p>Yesterday i have started GROS - OS on Rust! But I haven’t published code yet because it not have that minimum of funcionality that i want. Thanks for that site for teaching how to make basics - <a href="https://os.phil-opp.com">https://os.phil-opp.com</a></p>
|
|
|
|
<p>So it was first of GRU Devlog! Thanks for reading! If you want to contribute to some of that project write me an email - <a href="mailto:g1n@ttm.sh">g1n@ttm.sh</a> , or contact me in other ways</p>
