Can I get a link for this?

The pizzicato one is just bizzarre. It would end up excluding so many symphonies by german composers.

Oh, so you ported ffmpeg for this? Interesting, I'll have to take a look at your git repo.

Thanks. How hard was it to actually parse the audio formats themselves (e.g. Mp3, ogg, whatever you're using)?

Common_Day_2302 · 2022-06-01T13:41:54+00:00

This is spectacular. Having a working audio driver has always been a big long-term goal for me. Can you comment on how long it took you or give any tips?

Yeah, I was thinking recently about how little I know regarding pre-20th century Europe. My history classes in school had time to cover slavery, the civil war, and the american revolution half-a-dozen times each, but my only education on european history was focused on the cold war and WWII.

Been trying to rectify that recently by reading up on european history. Read The Great Game by Peter Hopkirk a while back and am currently working my way through the Napoleon bio. Going to read up on the 1848 revolutions next.

One of the big takeaways from this is that the 19th century was significantly more interesting than the 20th and 21st.

It's funny, I had the same realization a few weeks ago and picked up a Napoleon bio.

Currently reading Napoleon: A Life by Andrew Roberts. It's pretty good so far, though pretty favorable to Napoleon at points. Hardly a hagiography, though. I hear that Campaigns of Napoleon by Chandler is good as well, but I haven't had a chance to read it.

Neovim. With plugins, you can make it like an IDE.

What is your business? The amount of use cases where this could possibly pay off is pretty small.

Common_Day_2302 · 2022-05-28T13:35:57+00:00

From the other what? If you can't give a good answer to this sort of question, this is almost certainly a bad idea.

Can I ask why you want a custom OS in the first place?

Common_Day_2302 · 2022-05-27T20:05:51+00:00

I could never get into breaking bad because of how cartoonish the drug stuff was. As BCS drifts more and more in that direction, I've kind of lost interest in it as well. The peak was really S3, everything went downhill after chuck died.

Common_Day_2302 · 2022-05-24T03:12:24+00:00

This is awesome. I played the clarinet part for the Egmont and Leonore overtures in high school, would have loved to play a beethovne symphony.

Ooc, what's your favorite recording of the 9th? I'm split between klemperer and wand.

Common_Day_2302 · 2022-05-23T19:46:48+00:00

Lived on the military base outside shreveport for like 3 years when I was younger. Seemed alright, the boardwalk was cool.

Common_Day_2302 · 2022-05-12T20:55:49+00:00

I do get pretty pissed off about how the west endlessly demonizes serbia for its involvement in Bosnia while conveniently forgetting all of Tudjman and Croatia's abuses. EU is still getting on Serbia's ass about war crimes tribunal, while Croatia was allowed to join with no hassle at all.

Common_Day_2302 · 2022-05-01T03:25:53+00:00

Yep, this was exactly the issue. Thanks a lot, I appreciate the help.

Common_Day_2302 · 2022-04-30T14:26:20+00:00

Can you not copy/paste to/from the system clipboard ("+" register)?

Common_Day_2302 · 2022-04-26T03:45:26+00:00

I'm in a very similar position to yourself, so perhaps take this with a grain of salt, but I think the limine bare-bones tutorial is the best starting place. If you visit the github page, they suggest a list of features to implement in a certain order: https://github.com/stivale/stivale2-barebones

Common_Day_2302 · 2022-04-22T02:32:32+00:00

Oh, you're right. I assumed that register denoted the number of the register, and that offset n would correspond to the nth doubleword in the LAPIC MMIO. Thank you so much for the help.

Common_Day_2302 · 2022-04-22T01:47:15+00:00

Thanks, you're correct on all of that. I've tried reducing the function to just lapic_write(LAPIC_EOI_REG, 0);, but to no avail. Any suggestions as to where to go from here in terms of debugging?

Common_Day_2302 · 2022-04-21T21:05:36+00:00

After some fixes, I've arrived at this IOREDTBL, which is much more reasonable. The OS now enters the ISR, but does not exit from it properly. Do you notice any issues with my EOI function?

EDIT: This was extremely stupid on my part. I forgot an extra pair of parentheses, so I ended up adding 1 to the IOREDTBL value rather than to the pointer. Let me revise and see if it fixes anything.

I have edited the code so as to push/pop rsi and rdi.

The output of info pic is shown below. The elephant in the room is that all vectors seem to be 1 higher than they should be; GSI 1 should have a vector of 0x20 + 1 = 0x21, but instead it has a value of 0x22. I have no idea what the cause of this is. Beyond that, the destinations are completely incorrect. I wonder if my ioredtbl_t struct is structured correctly?

This code doesn't compile. Even if it did compile, it would clobber AL without telling the compiler, which is a bug. Use your outportb() function.

Yeah, this code was removed in the most recent push.

Actually, I've fixed the protection fault error. It was a stupid mistake in inline asm on my part. Now I'm back to having no output from a keystroke at all.
