[PATCH 0/5] Patches to get the information and data of EEPROM

[PATCH 0/5] Patches to get the information and data of EEPROM

[Zijie Pan]

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

Quite a few checkpatch warnings regarding long lines, but did a quick 
test with ixgbe and on the whole it looks good to me. CC the 
ixgbe/e1000/i40e maintainers on any v2 patchset, as they might catch 
something I've missed.

[PATCH v2 0/5] get the information and data of EEPROM

[Zijie Pan]

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

[PATCH v3 0/5] get the information and data of EEPROM

[Zijie Pan]

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

New APIs needs to be experimental at least first release they are introduces,
can you please mark them as experimental?

Please add the usual EXPERIMENTAL warnings for the new functions.

As noticed by Ferruh, they should be experimental.

Wasn't able to test the e1000/i40e callbacks but that aside the patchset 
looks good to me. Extend my previous ack to the whole series.

[PATCH v4 0/5] get the information and data of EEPROM

[Zijie Pan]

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

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.

I am not sure "plugin module" is descriptive enough.
And I think the structure name should be rte_eth_dev_module_info
to make clear that we are talking about NIC modules.
Any better idea?

Here is the description when "man ethtool":
-m --dump-module-eeprom --module-info
    Retrieves  and if possible decodes the EEPROM from plugin modules, e.g SFP+, QSFP.
Is there any suggestion how to describe it?

> Any better idea?
Yes, rte_eth_dev_module_info is better than rte_dev_module_info.
But the name of other structures should be also changed. And the file name
should be changed to rte_eth_dev_info.h.
Do we need to make a patch first to change the name of the file and structures?

I put the functions after rte_eth_dev_set_eeprom(). Please apply the patch and check it.

No you can just focus on your change.
If more clean-up is required in your opinion, you can do it later.

New APIs needs to be experimental at least first release they are introduces,
can you please mark them as experimental?
