ct-bugcheck: Add tools to poll for and report ath10k firmware crashes.
This tool can periodically check for ath10k firmware crashes. If it finds a crash, it will package up the binary crash dump, some OS level things like dmesg, lspci, etc into a tar file. It then notifies the user about the crash and asks them to report the bug to the appropriate email address. This is most useful when used with ath10k-ct driver and CT ath10k firmware, but it should also report issues with stock ath10k driver and firmware in case one has appropriate contacts to debug them. This tool could be extended later for other modules/bugs/etc. Signed-off-by: Ben Greear <greearb@candelatech.com>

Scripts to check for bugs (like firmware crashes) and package them for reporting.
|
||||
Currently this script only checks for ath10k firmware crashes.
|
||||
Once installed, you can enable this tool by creating a file called
|
||||
/etc/config/bugcheck with the following contents:

||||
DO_BUGCHECK=1
|

export DO_BUGCHECK
