💅 ACCEL-CONFIG CONFIG-DEVICE — the accfg manual, bestie edition

Okay so hi, welcome, this is accel-config config-device from the accfg manual, and it's literally the page where you get to poke at every little attribute on your device one by one. It's giving "customizing your avatar but the avatar is a hardware accelerator." Obsessed. 🎀

Oh and heads up, this whole thing lives in section 1 of the manual, so like, it's a user command, not some deep kernel lore. Iykyk.

✨ NAME ✨

accel-config-config-device — configure the individual attributes of the device 🦋

Like, singular. One device. Your device. The attributes are hers to tweak now.

🌸 SYNOPSIS 🌸

accel-config config-device <device name> [<options>]

So you give her the device name, and then you can sprinkle on some <options> if you're feeling spicy. That's the whole vibe.

🍓 EXAMPLE 🍓

Here's one that just works, no cap:

accel-config config-device dsa0 --read-buffer-limit=1

Touching dsa0, setting her read buffer limit to 1. Iconic. ✨

💖 OPTIONS 💖

Two (2) options. That's it. Short page, big power.

  • -l, --read-buffer-limit= — bestie listen, this sets the maximum number of read buffers that can be in use at one time by operations that go access low bandwidth memory. 💀 And here's the important part: that number of read buffers is shared by all descriptors that access low bandwidth memory across the entire device. Whole. Entire. Device. So don't be selfish with it. Also read-buffer-limit should be more than 0 — zero is not the move, babe. 🙈
  • -e, --event-log-size= — this one says how many entries live in the event log. The valid range is 64-65535, so stay inside those walls, okay? Going outside is not a slay. 👑
