I didn’t bisect the change, but the refactoring of the init methods looks like the reason for the change of behavior. As it’s not documented in the commit message, was that intentional? I think it breaks Linux’ no regression rule, and the commit (and follow-ups) should be reverted in Linux v5.17 and backed out from the stable series. Kind regards, Paul ¹ Why can’t even without proper firmware, the card at least initialize to have a network connection even if it’s degraded? ^ permalink raw reply [flat|nested] 21+ messages in thread

Top-posting for once, to make this easily accessible to everyone. To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced b7a49f73059fe6147b6b7 #regzbot title firmware now as to be in the initramfs #regzbot ignore-activity If it turns out this isn't a regression, free free to remove it from the tracking by sending a reply to this thread containing a paragraph like "#regzbot invalid: reason why this is invalid" (without the quotes). Reminder for developers: when fixing the issue, please add a 'Link:' tags pointing to the report (the mail quoted above) using lore.kernel.org/r/, as explained in 'Documentation/process/submitting-patches.rst' and 'Documentation/process/5.Posting.rst'. Regzbot needs them to automatically connect reports with fixes, but they are useful in general, too. Sending this just to the lists, as this seems to be handled already. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.

You may want to apply this commit to resolve the problem. commit e13ad1443684f7afaff24cf207e85e97885256bd Author: Manish Chopra <manishc@marvell.com> Date: Wed Feb 23 00:57:20 2022 -0800 bnx2x: fix driver load from initrd Commit b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") added new firmware support in the driver with maintaining older firmware compatibility. However, older firmware was not added in MODULE_FIRMWARE() which caused missing firmware files in initrd image leading to driver load failure from initrd. This patch adds MODULE_FIRMWARE() for older firmware version to have firmware files included in initrd.

It’s not about firmware version 7.13.15.0 not being loaded, but as written, about the code being changed, so the firmware files are required earlier now. For unknown reasons to me `bnx2x_init_firmware()` is now also called in `bnx2x_init_bp()`, which is probably an earlier code path. (I do not know the driver, so please take everything I write with a grain of salt.)

Alright, I don't see a revert in my inbox, so let me double check. Linus, is my understanding correct that our PR today should revert the patches in question [1]? Or just drop them from stable for now, and give Manish and team a week or two to figure out a fix? Manish, assuming it's the former - would you be able to provide a revert within a couple of hours (and I mean "couple" in the British sense of roughly two)?

Linus, does "you can't request FW before system is up and running" translate to "don't request FW at probe" or "don't request FW in initrd?" Or perhaps something else?

So things should work as it is with the mentioned fixed commit. The only discussion led by this problem now is why the request_firmware() was moved early on [from open() to probe()] by the patch in subject. I explained the intention to do this in my earlier emails and let me add more details below - Note that we have just moved request_firmware() logic, *not* something significant which has to do with actual FW loading or device initialization from the FW file data which could cause significant functional change for this device/driver, FW load/init part still stays in open flow. Before the patch in subject, driver used to only work with fixed/specific FW version file whose version was statically known to the driver function at probe() time to take some decision to fail the function probe early in the system if the function is supposed to run with a FW version which is not the same version loaded on the device by another PF (different ENV). Now when we sent this new FW patch (in subject) then we got feedback from community to maintain backward compatibility with older FW versions as well and we did it in same v2 patch legitimately, just that now we can work with both older or newer FW file so we need this run time FW version information to cache (based on request_firmware() return success value for an old FW file or new FW file) which will be used in follow up probe() flows to decide the function probe failure early If there could be FW version mismatches against the loaded FW on the device by other PFs already So we need to understand why we should not call request_firmware() in probe or at least what's really harmful in doing that in probe() if some of the follow up probe flows needs some of the metadata info (like the run time FW versions info in this case which we get based on request_firmware() return value), we could avoid this but we don't want to add some ugly/unsuitable file APIs checks to know which FW version file is available on the file system if there is already an API request_firmware() available for this to be used.

Thanks. I think you are asking "why can't we call request_firmware() at probe time?", right? If so, try it and see why it fails. Build the driver into the kernel image, do not use an initramfs, and see what happens. Again, wait until open() to call it, then you have a working userspace, including a filesystem where the firmware actually will be. Before then, you might not. thanks, greg k-h ^ permalink raw reply [flat|nested] 21+ messages in thread

In the following examples, the driver was not built-in to the kernel but loaded from the root filesystem instead, so there is no initramfs related problem here.

That's why you are not able to locate them in /lib/firmware/bnx2x/ Please check/scan the system environment if there are any OOB modules/PMDs installed or running on the same adapter by any chance ? Maybe perhaps re-installing the kernel with fix and making a cold boot/power cycle of the server will make this issue go away too.? Even after all these if it still report about the odd loaded firmware, it should be fine informatively as the driver fix now also relax the strict FW versions comparisons (against already loaded_fw by any chance) to allow these close oob firmwares to be backward compatible instead failing the device load abruptly. BTW, 1. Can you please provide the complete system logs (/var/log/messages or dmesg -T) and other relevant info (like lspci, ip link show etc.) for any issues ? 2. Does system has only these two NIC controllers with total 4 PCI functions (two to each) ? No any other PCI functions on any of these controllers used in some different environment ?
