ccr(4) — Chelsio T6 crypto accelerator driver 💖✨

okay so bestie, this is ccr(4), straight outta the Kernel Interfaces Manual, and it is literally the manual page for the Chelsio T6 crypto accelerator driver. group-chat energy: on. facts: untouched. let's go 🫶

🧚 NAME 🧚

ccr — the Chelsio T6 crypto accelerator driver, no cap.

🌸 SYNOPSIS 🌸

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device ccr
device cxgbe

To load the driver as a module at boot time, place the following line in loader.conf(5):

ccr_load="YES"

💅 DESCRIPTION 💅

The ccr driver provides support for the crypto accelerator engine included on PCI Express Ethernet adapters based on the Chelsio Terminator 6 ASIC (T6). It accelerates these operations for crypto(9) consumers such as ktls(4), geli(4), and ipsec(4):

  • AES-CBC
  • AES-CCM
  • AES-CTR
  • AES-GCM
  • AES-XTS
  • SHA1
  • SHA2-224
  • SHA2-256
  • SHA2-384
  • SHA2-512
  • SHA1-HMAC
  • SHA2-224-HMAC
  • SHA2-256-HMAC
  • SHA2-384-HMAC
  • SHA2-512-HMAC

iconic. The driver also supports chaining one of AES-CBC, AES-CTR, or AES-XTS with SHA1-HMAC, SHA2-224-HMAC, SHA2-256-HMAC, SHA2-384-HMAC, or SHA2-512-HMAC for encrypt-then-authenticate operations.

For further hardware information and questions related to hardware requirements, see http://www.chelsio.com/.

The ccr driver attaches as a child of an existing Chelsio NIC device and thus requires that the cxgbe(4) driver be active. iykyk 💅

🎀 HARDWARE 🎀

The ccr driver supports the crypto accelerator engine included on adapters based on the T6 ASIC:

  • Chelsio T6225-CR
  • Chelsio T6225-SO-CR
  • Chelsio T62100-LP-CR
  • Chelsio T62100-SO-CR
  • Chelsio T62100-CR
