mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Gérald Kerma]

Héllo All,

I made some few tests on EspressoBin-Ultra from GlobalScaleTechnologies,
because of problem with the WiFi.

I have done some quick tests on all the firmware of PCIEUSB-8997 using
the pcieuart8997_combo_v4.bin on OpenWrt 21.02.x

Here is a summary of the tests :
- W16.68.10.p159 = KO
- W16.68.1.p195 = KO
- V16.68.1.p145 = OK
- 16.68.1.p140 = OK
- 16.68.1.p133 = OK
- 16.68.1.p97 = OK
- 16.68.1.p70 = KO
 
REF (and all details of tests) :
https://github.com/NXP/mwifiex-firmware/issues/1


Broken firmware :

Version |W16.68.1.p195| of |pcieusb8997_combo_v4.bin| was included into
linux-firmware repository by this pull request:
https://lore.kernel.org/all/CA+5PVA5yQbjg3vaT7F8120B6ngLn7+sZC0OWt0KoUiQR9hS4FA@mail.gmail.com/
<https://lore.kernel.org/all/CA+5PVA5yQbjg3vaT7F8120B6ngLn7+sZC0OWt0KoUiQR9hS4FA@mail.gmail.com/>

And latest version |W16.68.10.p159| of |pcieusb8997_combo_v4.bin| by
this pull request:
https://lore.kernel.org/linux-firmware/CA+5PVA5on7+CRtEV7tThPxgucwt3W9i-tEXm4cgH-AmMB-Jrtg@mail.gmail.com/
<https://lore.kernel.org/linux-firmware/CA+5PVA5on7+CRtEV7tThPxgucwt3W9i-tEXm4cgH-AmMB-Jrtg@mail.gmail.com/>

Olders looks to works better.

In quick tests, they allow more than 1 clients at a time !

I am still testing the V16.68.1.p145 and report the results after some
longer use...

Hopes it will help...

From this user test result can be seen that last two versions of
pcieusb8997_combo_v4.bin firmware file for 8997 wifi+bt card with
official mainline linux kernel driver mwifiex were not properly tested
internally in NXP and are causing serious issues which make 8997 card
basically unusable.

Sharvari and other NXP developers: Do you have some internal testing of
this pcieusb8997_combo_v4.bin firmware for PCIe+USB variant of 8997
wifi chips? Or are you aware of this issue and do you have in NXP some
workaround for it (e.g. at driver level)? Could you please look at this
serious issue and try to debug firmware and release a new version, as
this is obvious fatal error in firmware itself?

Josh, how you in linux-firmware repository handle such, I must say,
"fatal issues"? Wait for vendor fixes or revert problematic commits? Or
something else?

Because when users starts upgrading linux-firmware packages in their
downstream distributions then basically wifi cards on this 8997 chips
with official mwifiex driver stops working.

We can revert if we need to, but I think it's not quite that simple.

The first broken version was committed in Feb of 2019.  That's
approaching 3 years ago.  Given that this is binary firmware, I have
no idea what else may or may not be included in the updates in the
meantime.

Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Gérald Kerma]

To be more correct :
older firmware allow more than 1 client at a time !
The two latest do not allow more than 1 client at a time...

Josh, do you have any contact in NXP? Because I really do no know how to
get some information about this issue and seems that everything related
to these firmware issues makes just big silence.

Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Pali Rohár]

Sharvari, Rakesh, Cathy, Zheng: could you please look at this issue?
NXP sent firmware to linux-firmware repository which does not work and
it is causing issues to users.

Josh, as Gérald wrote, current binary in linux-firmware repository is
unusable. And there is no reply from NXP for 3 months.

You are right that nobody knows what is in firmware binary, but working
binary is at least usable than non-working binary.

So I would really suggest to start reverting non-working firmware files
if NXP does not respond in few days.

Gérald, what is your opinion? Do you see other way how to make mainline
linux driver work (again)?

I am really lost on this, Marvell do not answer at all.
NXP give me some buggy answer, no NDA possible with me and my own company...
No share about any works already public !
So my only proposal will be poor !

May be we can confirm my own test by some other technical testers and 
look to get the less buggy, because they all, more or less, again to the 
mainline !

Hello Prashanth!

Thank you for reply. Did you have a time to check this issue?

Gérald did a great testing which shows that version W16.68.1.p195 and
higher of pcieuart8997_combo_v4.bin firmware does not work.

Hi Pali,

NXP doesn't have a plan to support mwifiex driver anymore. How should we handle this kind of retired project in upstream?

Thanks,
James

Re: [EXT] Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Gérald Kerma]

[-- Attachment #1: Type: text/plain, Size: 8848 bytes --]

Héllo James,

Was it only ever supported ?

May be NXP can free and share the firmware source to the community, and let anyone who care try to debug it ?

As far as my tests shown, the mwifiex driver never has work correctly, and none version is sufficiently stable to be state as working.

Please, NXP, take cares of your end clients !
Be simple, be smart, be respectuous, give us the source…

Thanks in advance,
Gérald Kerma

Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Pali Rohár]

Hello James!

Thank you for reply, but this is something which we did not want to hear :-(

There is an issue in the latest pcieuart8997_combo_v4.bin firmware file
which NXP sent to linux-firmware repository and it is really needed to
fix this issue. It was sent by NXP, so it is expected that NXP do it.
And because it is binary-only file, people outside of NXP cannot do it.

Would you be able to look at this firmware issue as the last thing?

Or as Gérald wrote, could NXP provide source code of that firmware? So
people outside of NXP could look at it? If firmware requires signing NDA
(either individually or via company), then some professional skilled
kernel developers can do it.

Re: [EXT] Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[James Cao]

[-- Attachment #1: Type: text/plain, Size: 10704 bytes --]

Hi Gérald, Pali,

For NXP Wi-Fi/BT FW, we only have binary release, which is under proprietary license.

Regarding the issue, which kind of adapter (PCIe-USB or PCIe-UART) did you use? Suppose PCIe-USB/PCIe-UART FW may not work on PCIe-UART/PCIe-USB board. What's the failure symptom?

Thanks,
James

Re: [EXT] Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Gérald Kerma]

Héllo James,

So bad to hear from no source possible !
About binaries, I cannot get the latest published one from NXP.
The support answer me I need a NDA.
The support then refuse my proposal of NDA !
I may understand proprietary license, but as a user, I cannot get 
nothing at all !

Regarding the issue, you can see the full details of my tests, and I 
just edit to add a brief summary at the first comment of the following 
issue:
https://github.com/NXP/mwifiex-firmware/issues/1

Please, look at it.
It is full detailed.
If anything missing, please, ask what you need.

Regards,
Gérald Kerma

Re: mwifiex 1.0 (16.68.10.p159) - PCIEUSB-8997 firmware is buggy

[Pali Rohár]

Hello James!

The issue which Gérald observing is that firmware version W16.68.1.p195
or new is unable to start access point on PCIe-USB 8997.

As Gérald wrote in that NXP ticket on github, error message is
following:

[56066.999853] mwifiex_pcie 0000:01:00.0: CMD_RESP: cmd 0xb1 error, result=0x1
[56067.007152] mwifiex_pcie 0000:01:00.0: Failed to start the BSS
[56067.013195] mwifiex_pcie 0000:01:00.0: Failed to start AP

Older firmware versions (e.g. V16.68.1.p145) are working fine.

James, do you need some more information?
