In the video I explained how I arrived at tracing __iwl_dbg() in this way, and how you can follow a similar approach for tracing unfamiliar code. This is not my best code, since I hacked it in a hurry, but here it is: #!/usr/bin/python Embedded C. # # Tone generation from: [link] # # 29-Apr-2019 Brendan Gregg Created this.
