Driver supports 2 types of core dumps.
- Live dump - Firmware dump when system is up and running.
- Crash dump - Dump which is collected during firmware crash that can be retrieved after recovery.
Crash dump is currently supported only on specific 58800 chips which can be retrieved using OP-TEE API only, as firmware cannot access this region directly.
User needs to set the dump flag using following command before initiating the dump collection:
$ ethtool -W|--set-dump eth0 N
Where N is "0" for live dump and "1" for crash dump
Command to collect the dump after setting the flag:
$ ethtool -w eth0 data Filename
v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n. Also change log message to netdev_info().
