CCP(4)

💅 CCP(4) — like, the whole page, bestie

okay so real talk: this is ccp(4) from the Kernel Interfaces Manual, and I'm gonna walk you through it like we're texting at 2am. no gatekeeping, no cap. 🫶

✨ NAME ✨

ccp — the AMD cryptographic co-processor, aka your kernel's little crypto bestie 💖

---

🎀 SYNOPSIS 🎀

how do we even get one of these bad boys? attach vibes only:

ccp* at acpi?
ccp* at fdt?
ccp* at pci?

like, it can show up via acpi, or fdt, or pci. three whole entrances, main character energy tbh 👑

🌸 DESCRIPTION 🌸

okay so the AMD cryptographic co-processor devices are literally out here doing the most: they provide offload for various cryptographic algorithms, they offload zlib compression and decompression, and on top of all that they've got a random number generator. multitalented. we stan. ✨

and the ccp driver? it supports feeding output of the random number generator into the kernel entropy pool. that's it, that's the flex. entropy queen behavior 🔥
