πŸ› οΈ SYNOPSIS πŸ› οΈ

int cscfg_register_csdev (struct coresight_device *csdev , u32
       match_flags , struct cscfg_csdev_feat_ops *ops );

πŸ’– ARGUMENTS πŸ’–

  • csdev β€” the coresight device you're registering, aka the main character of this call πŸ‘‘
  • match_flags β€” matching information used to load features; think of it as the little matchmaking vibe check πŸ’«
  • ops β€” the standard operations supported by the device, its lil toolbox 🧰

🌈 DESCRIPTION 🌈

Okay so this function registers the coresight device with the system. match_flags is used to check if the device is a match for registered features β€” it's giving matchmaker but for kernel stuff 😌.

Any currently registered configurations and features that match the device will be loaded onto it. That's the whole flex: the device shows up, the compatible configs and features say "hey bestie" and load right on πŸ’–


πŸ‘€ SEE ALSO πŸ‘€

The kernel file is ./drivers/hwtracing/coresight/coresight-syscfg.c β€” go peek if you want the lore πŸ“–


That's the whole page, bestie 🫢 it comes from ./drivers/hwtracing/coresight, dated October 2026, and it's the cscfg_register_csdev(9) manual tag β€” slay, bye πŸ’‹
