Copying some code here doesn't help really help.
Could you describe what we can expect in this string?
How can we compare this version number across different
devices of the same driver?
How does it apply to FPGA devices?
What is the potential use?

Why not returning some errors?

You forgot to remove the deprecation notice in this patch.

Qiming: The length is a number large enough to store the firmware version. Original I use a fixed number 20, but in order to be more flexible, I replace it into a variable.

Suggest description such as:

This patch adds ethdev API for fetching firmware version.

Also see Thomas's comments. Looks like some stale patches got picked up

[dpdk-dev] [PATCH v2 0/5] example/ethtool: add bus info and fw version get

[Qiming Yang]

Now, the example ethtool can only show the driver information. From
customers' point of view, it should be better if we can have the same
way that the Linux kernel ethtool does to show the bus-info and
firmware-version.

These five patches add a new API to fetch firmware version and implement
the display in example ethtool.

  ethdev: add firmware version get
  net/e1000: add firmware version get
  net/ixgbe: add firmware version get

Hi Qiming,

Not sure if I am missing something but this change is for following [1]
deprecation notice, right?
If so, notice suggest updating rte_eth_dev_info_get() to include
fw_version, but this patch adds a new eth_dev_ops.

Is it agreed to add a new eth_dev_ops for this?


[1]
* In 17.02 ABI change is planned: the ``rte_eth_dev_info`` structure
  will be extended with a new member ``fw_version`` in order to store
  the NIC firmware version.

Re: [dpdk-dev] [PATCH v2 1/5] ethdev: add firmware version get

[Yang, Qiming]

Hi, Yigit
Yes, we had planned to add  fw_version in rte_eth_dev_info_get(). But Remy think we should better to implement this feature through a way don't break the original ABI. So I change the implement.

This patch has dependence on your get_fw_version patch set.

I think you may misunderstand Ferruh's comments,
I think what he said was ask you to remove bus-info print (above line) from that patch set,
but keep firmware version print.

Hi, Remy
I'll add this update in v3 patch, thank you for your remind.
BTW, It looks like Yigit don't agree the implement we used, he think we'd better not add a new ops to get this info.

It must be a feature in the table (doc/guides/nics/features/).
The deprecation notice must be removed also.

I think it is OK to add a new dev_ops and a new API function for firmware
query. Generally speaking, it is a good thing to avoid putting all
informations in the same structure (e.g. rte_eth_dev_info). However, there
is a balance to find. Could we plan to add more info to this new query?
Instead of
	rte_eth_dev_fwver_get(uint8_t port_id, char *fw_version, int fw_length)
could it fill a struct?
	rte_eth_dev_fw_info_get(uint8_t port_id, struct rte_eth_dev_fw_info *fw_info)

We already have
	rte_eth_dev_get_reg_info(uint8_t port_id, struct rte_dev_reg_info *info)
with
	uint32_t version; /**< Device version */

Here there is another problem, the content and the format of the string
is not defined. In this patchset it is not same for different PMDs.
This is OK for just printing the data, but not good for an API. How can
the application know what to expect.

I believe this is better. But the problem we are having with this usage
is: ABI breakage.

Since this struct will be a public structure, in the future if we want
to add a new field to the struct, it will break the ABI, and just this
change will cause a new version for whole ethdev library!

When all required fields received via arguments, one by one, instead of
struct, at least ABI versioning can be done on the API when new field
added, and can be possible to escape from ABI breakage. But this will be
ugly when number of arguments increased.

Or any other opinion on how to define API to reduce ABI breakage?

You're right.
But I don't think we should have a function per data. Just because it would
be ugly :)
I hope the ABI could become stable with time.

I am no suggesting function per data, instead something like:

rte_eth_dev_fw_info_get(uint8_t port_id, uint32_t maj, uint32_t min);

And in the future if we need etrack_id too, we can have both in
versioned manner:

rte_eth_dev_fw_info_get(uint8_t port_id, uint32_t maj, uint32_t min);

rte_eth_dev_fw_info_get(uint8_t port_id, uint32_t maj, uint32_t min,
	uint32_t etrack_id);

So my concern was if the number of the arguments becomes too many by time.

Oh I see. So it can be versioned with compat macros.

It looks to be a good proposal. We should not have a dozen of arguments.

So, I suggest trying this approach in this API.


Overall, change request for the patch becomes:
1- Change API, is following arguments good enough to start with?:
- FW_major_number
- FW_minor_number
- FW_patch_number
- Etrack_id

If so, API becomes:
rte_eth_dev_fw_version_get(uint8_t port_id, uint32_t *fw_major,
	uint32_t *fw_minor, uint32_t *fw_patch, uint32_t *etrack_id);

! Note, I have renamed API to rte_eth_dev_fw_version_get() from
rte_eth_dev_fw_info_get() mentioned above, to narrow the scope of API.

and dev_ops name keeps same: fw_version_get

2- Add new feature in feature table (doc/guides/nics/features/), first
patch can add to the default one, and each driver patch implements this
feature should update its feature table.
Feature name can be "FW version"

3- Remove deprecation notice in the first patch.

ferruh

I'd suggest to do that the similar way of kernel driver/ethtool (Linux or FreeBSD) does,
which should be well discussed.
In addition, for future extention, and avoid breaking any ABI in a strcuture,
we can just pre-define a lot of bytes as reserved, e.g. 64 bytes. Inside DPDK,
there are several strucutres defined like this, e.g. mbuf.

I have a reserve about the naming etrack_id.
Please could you point to a document explaining this ID?
Is it known outside of Intel?

Re: [dpdk-dev] [PATCH v3 1/4] ethdev: add firmware information get

[Yang, Qiming]

Hi, Ferruh
Please see the question below. In my opinion, etrack_id is just a name used to define the ID of one NIC.
In kernel version ethtool, it will print this ID in the line of firmware verison. 
I know what is etrack_id mean, but I really don't know why this named etrack_id.
Can you explain this question?

Please reply below the question and on the mailing list.
You'll have to explain why this name etrack_id.

Hi Qiming,

I suggested the API based on fields you already used in your patch.

So, this API is to get FW version, is etrack_id something that defines
(part of) firmware version?

Thanks,
ferruh

Yes, in my opinion it is. And I use this name already exist in the share code from ND team.

Different HW may have different version format, so it is better to use string.

And I prefer the API definition in your v2 patch like

rte_eth_dev_fwver_get(uint8_t port_id, char *fw_version, int fw_length);

The problem with this is the format and content of the string is not
defined, as you said different HW has different version format. This is
no problem if you will only print the string.

But this is a public API, if an application wants to call this API and
do something useful according the FW version information, it will need
to parse the string, and it will not able to parse it because format of
the string is not defined. By making API fill some defined variables,
app won't need to parse them, and API output won't be HW dependent.

ferruh

As my understand, the firmware version is specific things to each HW. The format
cannot be generic at all, or at least we have no standard to follow. I think
the API should not be HW dependent, but about the output, application should know
What the string's meaning. Otherwise why we need to provide the firmware info?

I am for rte_eth_dev_fw_version_get(), to limit the scope of the API.
And API name and eth_dev_ops name should match..

I think you can use a struct as parameter here. But beware, that struct
should NOT be a public struct.

I think you can use a struct as parameter here. But beware, that struct should NOT be a public struct.
Qiming: I think only add a private struct for igb is unnecessary. Keep the arguments consistent with rte_eth_dev_fw_info_get is better.

Both are OK.
Normally, I believe using struct is better. But we are not using struct
in public API because of the ABI compatibility issues. Here it is
internal usage, there is no ABI breakage concern, so it may be possible
to use a struct.
But if you prefer to keep the arguments same here with public API, that
is fine.

This API at least provide major and minor fw versions I think. Isn't
there any kind of FW version information for ixgbe? Just providing
etrack_id is not looking good.

Re: [dpdk-dev] [PATCH v3 3/4] net/ixgbe: add firmware version get

[Yang, Qiming]

You can see the kernel version ethtool, use command 'ethtool -i  <ixgbe NIC name>'
driver: ixgbe
version: 4.2.1-k
firmware-version: 0x61bf0001

Ixgbe's FW version do not have the major and minor number, and the original purpose of this function is get FW version, so I think it's enough.

Is etrack_id a unique value that defines the FW version on its own?

And is above definition true for all NICs (or at least Intel ones)?
Because I can see i40e is using 4 bit value for etrack_id ?

Re: [dpdk-dev] [PATCH v3 3/4] net/ixgbe: add firmware version get

[Yang, Qiming]

Yes,  etrack_id is an unique value. But not all NICs have this value.
I didn't find any value about fw version in fm10k.
I40e is 8 bit too.

Is etrack_id a unique value that defines the FW version on its own?

And is above definition true for all NICs (or at least Intel ones)?
Because I can see i40e is using 4 bit value for etrack_id ?

Yes, you are right, following is from i40e datasheet:

"
The EEPROM Manager tool writes a unique 32-bit eTrack_ID number in two
sequential NVM words.
The eTrack_ID is written when EEPROM Manager tool creates an image on
the Intel network. The eTrack_ID DB tracks NVM images back to a specific
SCM build
"

So it is unique, and can be used to identify FW version. And yes it can
be enough on its own without having major minor FW version fields.

Right, I read it wrong, i40e also has 32bits etrack-id.

Thanks,
ferruh

[dpdk-dev] [PATCH v4 0/5] new API 'rte_eth_dev_fw_version_get'

[Qiming Yang]

Now, the example ethtool can only show the driver information. From
customers' point of view, it should be better if we can have the same
way that the Linux kernel ethtool does to show firmware-version.

These five patches added a new function ``rte_eth_dev_fw_version_get()``
to fetch firmware version related information and implement the
display in example ethtool.

Qiming Yang (5):
  ethdev: add firmware version get
  net/e1000: add firmware version get
  net/ixgbe: add firmware version get
  net/i40e: add firmware version get
  ethtool: dispaly firmware version

After reading few comments, I think it should just fill a string.
There is no way the firmware version can be generalized or standardized.
If the application wants to do some processing like number comparisons,
it has to be aware of the specific firmware version string format.
If you want to help the application to parse this string, it should be
a PMD specific API.

indentation is wrong here. Also it looks like major, minor assignment is
common and can be moved from if statement.

Do you need this check. I think it is not good idea to add this kind of
checks into ethtool app. Why not just print "%d.%d.%d %#X, major, minor,
patch, etrack" for all cases ?

My feeling is that if we're going to have driver-specific output, then 
the task of constructing the string should be pushed down into the PMDs. 
It would also solve the headache of trying to standardise, as Thomas has 
mentioned..

[dpdk-dev] [PATCH v5 0/5] new API 'rte_eth_dev_fw_version_get'

[Qiming Yang]

Now, the example ethtool can only show the driver information. From
customers' point of view, it should be better if we can have the same
way that the Linux kernel ethtool does to show firmware version.

These five patches added a new function ``rte_eth_dev_fw_version_get()``
to fetch firmware version related information and implement the
display in example ethtool.

May be size_t should be used for fw_length? Corresponding argument of 
the snprintf()
has size_t type, sizeof(drvinfo.fw_version) is used as value of the 
parameter.

Also the prototype does not provide a way to communicate that fw_length 
is insufficient
to store firmware version. I'd suggest snprintf()-like return value. It 
is pretty easy for PMD
to provide and convenient for the API function caller to handle.

Maybe dev argument to fw_version_get should be:
   const struct rte_eth_dev *dev

Maybe dev argument to fw_version_get should be:
   const struct rte_eth_dev *dev
Qiming: do you means the argument to ops fw_version_get? 
why should add 'const'? both two are OK, but we usually use struct rte_eth_dev *dev.

Does seem a bit odd to me as I don't think any of the other rte_dev_ops 
entrypoints use const. Maybe they should but if that's now policy (I've 
been under a rock recently) probably better to do them all in a seperate 
cleanup patchset..

DPDK is somewhat lazy about using const.

It would be good to have same constants and format between Linux kernel
driver and DPDK.

Use %u as format specifier for unsigned values

static inline char *i40e_nvm_version_str(struct i40e_hw *hw)
{
	static char buf[32];
	u32 full_ver;
	u8 ver, patch;
	u16 build;

	full_ver = hw->nvm.oem_ver;
	ver = (u8)(full_ver >> I40E_OEM_VER_SHIFT);
	build = (u16)((full_ver >> I40E_OEM_VER_BUILD_SHIFT) &
		 I40E_OEM_VER_BUILD_MASK);
	patch = (u8)(full_ver & I40E_OEM_VER_PATCH_MASK);

	snprintf(buf, sizeof(buf),
		 "%x.%02x 0x%x %d.%d.%d",
		 (hw->nvm.version & I40E_NVM_VERSION_HI_MASK) >>
			I40E_NVM_VERSION_HI_SHIFT,

That memset is redundant since dev_info_get() does memset as first thing.

[dpdk-dev] [PATCH v6 0/5] new API 'rte_eth_dev_fw_version_get'

[Qiming Yang]

v6: - renamed fw_length -> fw_size
    - added return value for insufficient fw_size
    - fixed the indentation problem in e1000
    - added ver.build.patch in i40e, keep the same with Linux kernel driver

v5: - modified the API rte_eth_dev_fw_version_get(uint8_t port_id,
      char *fw_version, int fw_length).

v4: - removed deprecation notice
    - renamed API as rte_eth_dev_fw_version_get
    - splited bus info print from this patch set

v3: - changed API, use rte_eth_dev_fw_info_get(uint8_t port_id,
      uint32_t *fw_major, uint32_t *fw_minor, uint32_t *fw_patch,
      uint32_t *etrack_id)
    - added statusment in /doc/guides/nics/features/default.ini and
      release_17_02.rst

v2: - fixed commit log

Now, the example ethtool can only show the driver information. From
customers' point of view, it should be better if we can have the same
way that the Linux kernel ethtool does to show firmware version.

These five patches added a new function ``rte_eth_dev_fw_version_get()``
to fetch firmware version related information and implement the
display in example ethtool.

[dpdk-dev] [PATCH v8 0/5] new API 'rte_eth_dev_fw_version_get'

[Qiming Yang]

v8: - defined the minimum fw version size as a macro.

v7: - rebased

v6: - renamed fw_length -> fw_size
    - added return value for insufficient fw_size
    - fixed the indentation problem in e1000
    - added ver.build.patch in i40e, keep the same with Linux kernel driver

v5: - modified the API rte_eth_dev_fw_version_get(uint8_t port_id,
      char *fw_version, int fw_length).

v4: - removed deprecation notice
    - renamed API as rte_eth_dev_fw_version_get
    - splited bus info print from this patch set

v3: - changed API, use rte_eth_dev_fw_info_get(uint8_t port_id,
      uint32_t *fw_major, uint32_t *fw_minor, uint32_t *fw_patch,
      uint32_t *etrack_id)
    - added statusment in /doc/guides/nics/features/default.ini and
      release_17_02.rst

v2: - fixed commit log

Now, the example ethtool can only show the driver information. From
customers' point of view, it should be better if we can have the same
way that the Linux kernel ethtool does to show firmware version.

These five patches added a new function ``rte_eth_dev_fw_version_get()``
to fetch firmware version related information and implement the
display in example ethtool.

How to know the required size?
You should return the size of the non truncated string as snprintf does.
Note: Andrew Rybchenko already commented on it and you didn't reply.

[dpdk-dev] [PATCH v9 0/5] new API 'rte_eth_dev_fw_version_get'

[Qiming Yang]

v9: - when fw_size is insufficient, return the size of the non truncated
      string as snprintf does.

v8: - defined the minimum fw version size as a macro.

v7: - rebased

v6: - renamed fw_length -> fw_size
    - added return value for insufficient fw_size
    - fixed the indentation problem in e1000
    - added ver.build.patch in i40e, keep the same with Linux kernel driver

v5: - modified the API rte_eth_dev_fw_version_get(uint8_t port_id,
      char *fw_version, int fw_length).

v4: - removed deprecation notice
    - renamed API as rte_eth_dev_fw_version_get
    - splited bus info print from this patch set

v3: - changed API, use rte_eth_dev_fw_info_get(uint8_t port_id,
      uint32_t *fw_major, uint32_t *fw_minor, uint32_t *fw_patch,
      uint32_t *etrack_id)
    - added statusment in /doc/guides/nics/features/default.ini and
      release_17_02.rst

v2: - fixed commit log

I think it would be good to handle difference from snprintf() behaviour 
here and specify
that fw_version_get callback has exactly snprintf()-like return value. 
It would allow to avoid
duplicated code in all drivers (adding 1 for terminating null, 
conversion of success value to 0).
Also I think warning about insufficient space is not required. It could 
be intentional to call
the first time with 0 (or some small) space to get required space to be 
(re)allocated.
May be debug level message would be useful.

If we finally have different return value for

it would be useful to highlight it here.

It is OK for me to keep 0 for success here and it is right in this case 
to include terminating null
iin the return value if size is insufficient (to cover corner case with 
empty FW version).
Please, highlight that terminating null is included here. It is the 
difference from snprintf() and
it should be 100% clear.

But I think it would be better to just keep the way it is. If I handle snpritf() behavior here,
may the function rte_eth_dev_fw_version_get and ops fw_version_get will have different 
definition of return value.

Good advice, when call this function with 0, this function will become a API to get
firmware version size. I think we can remove the warning message here.

If I keep the handle of snprintf() return value in drivers, they will not have different
return here, so the highlight is not necessary.

You are right, I'll highlight that the firmware version stored here is include '\0'.

[dpdk-dev] [PATCH v9 5/5] ethtool: display firmware version

[Qiming Yang]

This patch enhances the ethtool example to support to show
firmware version, in the same way that the Linux kernel
ethtool does.

[dpdk-dev] [PATCH v10 0/5] new API 'rte_eth_dev_fw_version_get'

[Qiming Yang]

v10:- highlighted that terminating null is included in the output string array.
      removed the warning message in drivers.

v9: - when fw_size is insufficient, return the size of the non truncated
      string as snprintf does.

v8: - defined the minimum fw version size as a macro.

v7: - rebased

v6: - renamed fw_length -> fw_size
    - added return value for insufficient fw_size
    - fixed the indentation problem in e1000
    - added ver.build.patch in i40e, keep the same with Linux kernel driver

v5: - modified the API rte_eth_dev_fw_version_get(uint8_t port_id,
      char *fw_version, int fw_length).

v4: - removed deprecation notice
    - renamed API as rte_eth_dev_fw_version_get
    - splited bus info print from this patch set

v3: - changed API, use rte_eth_dev_fw_info_get(uint8_t port_id,
      uint32_t *fw_major, uint32_t *fw_minor, uint32_t *fw_patch,
      uint32_t *etrack_id)
    - added statusment in /doc/guides/nics/features/default.ini and
      release_17_02.rst

v2: - fixed commit log

Now, the example ethtool can only show the driver information. From
customers' point of view, it should be better if we can have the same
way that the Linux kernel ethtool does to show firmware version.

These five patches added a new function ``rte_eth_dev_fw_version_get()``
to fetch firmware version related information and implement the
display in example ethtool.

[dpdk-dev] [PATCH 5/5] ethtool: dispaly bus info and firmware version

[Qiming Yang]

This patch enhances the ethtool-API to support to show the
bus information and firmware version as same as kernel
version ethtool displayed.
