Whenever firmware crashes, and both CONFIG_ATH10K_DEBUGFS and CONFIG_ALLOW_DEV_COREDUMP are enabled, dump information about the crash via a devcoredump device. Dump can be read from userspace for further analysis from: /sys/class/devcoredump/devcd*/data As until now we have provided the firmware crash dump file via fw_crash_dump debugfs keep it still available but deprecate and a warning print that the user should switch to using dev_coredump. Future improvement would be not to depend on CONFIG_ATH10K_DEBUGFS, as there might be systems which want to get the firmware crash dump but not enable debugfs. How to handle memory consumption is also something which needs to be taken into account.
