Add APIs to read information from the DPDK applictions.
It can be used to dump the EEPROM of plugin modules (SFP+, QSFP, etc.).
Two APIs are introduced to access eeprom:
- rte_eth_dev_get_module_info
- rte_eth_dev_get_module_eeprom
Applications based on DPDK can dump eeprom by calling those two APIs.
Then, each PMD has to implement these callbacks for e1000, ixgbe, i40e, etc.
Patch for example/ethtool is used to test this function. It can get the raw
data of eeprom. See below how both DPDK applications (ethtool) and Linux
kernel are dumping the same eeprom of a same NIC.
- Start example/ethtool:
./examples/ethtool/ethtool-app/x86_64-native-linuxapp-gcc/ethtool -c 0xf -n 4 --socket-mem 1024,0 -- -i
EthApp> drvinfo
Port 0 driver: net_ixgbe (ver: DPDK 18.05.0-rc0)
firmware-version: 0x18b30001
bus-info: 0000:04:00.0
EthApp> module-eeprom
[UINT16]: module-eeprom <port_id> <filename>
Dump plug-in module EEPROM to file
EthApp> module-eeprom 0 my-module-eeprom.bin
Total plug-in module EEPROM length: 512 bytes
EthApp> quit
- HexDump of this eeprom file:

Both DPDK's my-module-eeprom.bin and Kernel's meeprom-kernel.bin
are the same.
v2 changes:
- Fix typo in features.rst.
- Fix checkpatch warnings regarding long lines.
- Update function pcmd_module_eeprom_callback().
v3 changes:
- fix compilation when dpdk is compiled with shared libs.
v4 changes:
- add RTE_ prefix for the macros defined in rte_dev_info.h.
- mark the new APIs as experimental.
- some other minor fixes.
Zijie Pan (5):
ethdev: add access to eeprom
examples/ethtool: add a new command module-eeprom
net/ixgbe: add module EEPROM callbacks for ixgbe
net/e1000: add module EEPROM callbacks for e1000
net/i40e: add module EEPROM callbacks for i40e
