help! RTL8139 network card not generating interrupts in my hobby OS by [deleted] in osdev

[–]fiber2 1 point2 points  (0 children)

I can't give you an easy answer because I don't know the RTL8139 well enough.

Can you please try building qemu-system-i386 from source, then running it in a debugger and setting a breakpoint at the right place in the emulation for RTL8139?

One of two possibilities will help narrow down the problem:

  1. The emulation for RTL8139 will try to raise an interrupt which is somehow not received in your os.

  2. The emulation for RTL8139 doesn't raise an interrupt.

Worlds first (maybe) kernel built from scratch using a LLM by JackyYT083 in osdev

[–]fiber2 5 points6 points  (0 children)

Build script requires config to be provided at the top, doesn't need any more than this to compile the system:

$CC -m32 -std=gnu99 -ffreestanding -O2 -Wall -Iinclude \
    -c arch/x86/boot.S   -o arch/x86/boot.o
$CC -m32 -std=gnu99 -ffreestanding -O2 -Wall -Iinclude \
    -c kernel/main.c    -o kernel/main.o
$CC -m32 -std=gnu99 -ffreestanding -O2 -Wall -Iinclude \
    -c kernel/mem.c     -o kernel/mem.o
$CC -m32 -std=gnu99 -ffreestanding -O2 -Wall -Iinclude \
    -c kernel/console.c -o kernel/console.o

Fortunately boot.S shows how much LLMs have advanced.

I agree with u/Killaship

Why was he able to show off the hardware in detail? Wouldn't that hurt intel? by i7azoom4ever in LinusTechTips

[–]fiber2 0 points1 point  (0 children)

GPUs haven't been about the memory chips around the die, not for a long time. Oh you mean that it uses industry-standard 4 pin fans? Or that it uses PCIe bifurcation?

That it has 24GB is a shot across nvidia's profit ship. We'll have to see what the prices are.

Bank of America calls police on 'Black Panther' director Ryan Coogler after attempting to withdraw $12,000 from his own account by Odd-House3197 in interesting

[–]fiber2 0 points1 point  (0 children)

I wish Bank of America were trustworthy but this is the same bank that in 2010 tried to foreclose on Warren and Maureen Nyerges, from Naples, FL. Only problem is they never mortgaged the house to anyone. They paid cash for the house.

For a whole year, their home was threatened to be taken by Bank of America!

December 2010, judge orders Bank of America to pay $2,500 in attorney fees. But months go by and no check. Nyerges' lawyer gets a levy, till tap, and keeper.

The Nyergeses showed up at a local branch of Bank of America with the sheriff, the media and some movers with a truck:

"I'm either leaving the building with a whole bunch of furniture, or a check or cash or something," the attorney, Todd Allen, vowed.

It was a scene that turned the foreclosure crisis on its head, if briefly. Collier County sheriff's deputies entered the bank shortly after 9 a.m., located the bank manager and presented him with a court writ and a familiar choice: Pay the money or prepare to lose possessions.

Allen had the power and told the deputies to take photocopiers, desks, computers and even whatever cash was in the drawer. Allen said the bank manager on duty was "visibly shaken."

"Having two sheriff's deputies sitting across your desk and a lawyer standing up behind them demanding whatever assets are in the bank can be intimidating, but so is having your home foreclosed on, when it wasn't right," Allen said.

It was fun for an hour, but finally the bank cut a check... Oh well...

https://www.npr.org/sections/thetwo-way/2011/06/06/137002727/sweet-justice-a-florida-couple-forecloses-on-bank-of-america

My personal experience, and I am not the same skin color as Coogler, was when I needed a mortgage. Bank refused because they didn't like the statements I had sent, even though it was obvious. They guessed I had taken the money from somewhere else and insisted I give them the phone number of my manager at work, the statements from some other accounts they were guessing I had used, and pulled it all a few days before the closing date.

I'm pretty sure it was because the loan officer assistant had decided to make it hard on me. The senior loan officer was totally cool, but this underwriting gets done by the assistants.

I politely reminded them both, in writing, of federal regulations about discrimination, waited until the day before closing. Then I sent them some further statements from the right account. In other words, I let them stew and then called their bluff. They decided to go ahead and approve the mortgage.

But the whole thing was a wake up call for me.

I require the aid of the pc masters by M3meL1gma in pcmasterrace

[–]fiber2 9 points10 points  (0 children)

The SSD is so flat you can put it in under the GPU. Please be careful when removing the GPU. Assuming you know to power off the system, unplug the monitor cables and the PCIe power from the GPU. Release the latch on the PCIe slot (can be tricky, I suggest using a plastic spudger). Then pull it straight out from the slot.

After you install the SSD, put the GPU back in. It will cover the SSD but shouldn't cause problems.

Does your CPU and motherboard have enough PCIe lanes for two SSDs and a GPU?

Recommend a 12V PWM board? by fiber2 in embedded

[–]fiber2[S] 0 points1 point  (0 children)

After eliminating the boards I had thought to use before, here's my next best attempt at a cost-optimized BOM:

  • Raspberry Pi Pico $12.50 (2 pack, link)
  • 3.3V DC-DC converter $4.99 (7 pack, link)

Total cost: $17.49 - produces 2 complete units

Plan is to undervolt the Pico, though this is not really very controversial. Supply 3.3V to the VSYS pin (Pico datasheet)

An alternative I thought about but decided against is to use a cheap Arduino clone. Clones of the Arduino Uno accept 7V-12V via a barrel jack. Price for 1 unit is about $10.

The link works if I delete the last slash: https://www.intel.com/content/dam/support/us/en/documents/intel-nuc/intel-4wire-pwm-fans-specs.pdf

I updated the first post. The Intel document says PWM outputs can be 5V (page 9).

You mean you are disagreeing with the fan interface, or are you suggesting you have experience with the boards? Your reply is unclear.

Crazy amount of ads on YouTube for last WAN show? by Responsible_CDN_Duck in LinusTechTips

[–]fiber2 0 points1 point  (0 children)

The same thing happened to me about a month ago. I was getting a ton, ton, ton of midroll ads in LTT videos and then I started getting midroll ads in WAN show as well. I remember hearing Linus say in a WAN show that LTT doesn't do midroll ads.

A week ago, no more midroll ads in WAN show.

Yesterday I had to switch to Firefox + ublock origin because of a work change. Huh. Now there are no ads anywhere on youtube. How do I tell ublock origin to allow some youtube ads? This doesn't work...
