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.

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. > > 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... > > Regards, > > Gérald Kerma > > gandalf(at)gk2(dot)net > ^ permalink raw reply [flat|nested] 20+ messages in thread

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. josh > > > 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... > > > Regards, > > > Gérald Kerma > > > gandalf(at)gk2(dot)net > > ^ permalink raw reply [flat|nested] 20+ messages in thread

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?

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?

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.

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.

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 ! >>>>> 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... >>>>> Regards, >>>>> Gérald Kerma >>>>> gandalf(at)gk2(dot)net ^ permalink raw reply [flat|nested] 20+ messages in thread
