@BigSkyRider @lupyuen I've had a look at this for an upcoming publication on embedded data distribution. Delta compression looks feasible, as long as there isn't too heavy optimization in place (LTO and similar) -- but the network has to support full updates anyway (eg. for compiler updates), and then update diffusion can cut traffic to a fraction.

Several fixes have been committed to the #OpenBSD iwm and iwx #wifi drivers. My goal is to have a stable base for upcoming changes.
If you have been seeing "iwm0: fatal firmware error" and such in the logs, upgrading to -current will hopefully fix this (with build date after June 30, 09:45h UTC).
And if you aren't seeing any issues then please try the next round of changes

@lupyuen Huh, neat how much "closed source" code is out there if you only look for it.
#BL602 #WiFi Firmware: 87,000 lines of Decompiled Code have been classified ... 24,000 more lines to go!

2,500 lines of Decompiled Code in #BL602 #WiFi Supplicant seem to match Rockchip RK3399 ... Leaving 700 lines to be deciphered
