Title: RTL8822be driver not found in Tinycore64 11.x
Post by: mrjake2 on March 02, 2020, 11:59:56 PM
Hello,

I saw a thread for 9.x where Juanito had made a tcz for the wireless driver rtl8822be-KERNEL.  It looks like this hasn't been created yet for 11.x .  Would it be possible to create it for 11.x and add it to the extensions repo?  I need it for Tinycore64 but others will probably need it for the standard tce repo as well.

(admin: you can move this topic if needed as the direction has changed.)

I actually went ahead and used the previous posts I found to compile this myself for Tiny Core 64 and it works.  I'd like to submit a tcz of this (currently testing it now), but I have a few questions.

1) Since it deals with firmware it has a non-standard license from Realtek.  The author of the code that uses that firmware has not included a separate license for his own work.  So I'm assuming the firmware files are covered under the Realtek license, and any other files are covered by standard copyright of the original author.  Is that correct?  FYI this is the Realtek license file: https://github.com/lwfinger/rtlwifi_new/blob/master/firmware/rtlwifi/Realtek-Firmware-License.txt

2) I don't believe this package has any dependencies since it's just firmware and drivers (although it won't actually do anything useful if you don't also install wireless-KERNEL).  Am I correct that I don't need to add any deps here?

3) Once I've tested it out, where do I send the archive file with everything necessary to submit the tcz to the repo?

Not sure why I can sometimes edit my previous messages and why sometimes I can't, so I'm just replying to the topic...

I found the answer to #3 in the wiki page for building tcz's so I'm assuming that information is still accurate.  I'm able to load my extension now, but I'm running into another issue that I'll need to clean up before I submit the package for inclusion in the repo. 

I'd still like answers to my first 2 questions from the previous post.  Additionally:

3a) The package I'm building does not include DESTDIR, but it is also an extremely simple Makefile.  I just looked at the install target in the Makefile, and used that to figure out where it was putting the files (confusingly, it actually seems to copy the firmware files twice - once explicitly to /lib/firmware and once to ${FIRMWAREDIR}/lib/firmware - but when I manually put them in /usr/local/lib/firmware instead of /lib/firmware it seems to work fine).  I manually copied the compiled drivers and firmware into /tmp/wifi-rtw88 (preserving the paths from the install target under that).  I'm assuming that should work fine, but I'd like confirmation of that.

3b) submitcq thinks everything is ok other than the license file issue mentioned above.  I then test this by copying the tcz file into my tce directory, booting up my USB on my laptop, and then loading the extension.  When I do that, though, I get the following output:

Code: [Select]
tc@box:~$ tce-load -il wifi-rtw88
loading out-of-tree module taints kernel.
rtw88: Unknown symbol ieeee80211_start_tx_ba_cb_irqsafe (err -2)
...

However after that I load wireless-KERNEL.tcz and wifi.tcz, and I'm able to connect to my access point.  What do those errors mean, and how do I fix them before submitting?

I'm attaching the makefile from the wireless driver package in case there is anything else in there that I'm missing.  The one item from the Makefile that I didn't explicitly handle in my tcz is "depmods -a ${KERNEL}", but since this module doesn't have any dependencies (that I know of) I assumed that step isn't actually necessary.  I don't know anything about depmods though, so please correct me if I'm wrong.

Hmm, I think it's actually the other way around, i.e. wireless-KERNEL relies on my code (wifi-rtw88.tcz) already being loaded.  If I try loading wireless-KERNEL first (or wifi.tcz, which first loads wireless-KERNEL),  then I get a bunch of errors and wifi won't start:

I tried, and that doesn't work.  The whole package structure for rtlwifi_new changed in the last year since Juanito last compiled it, so I'm not surprised that the dependencies have changed.  If you load wireless-KERNEL before wifi-rtw88, it definitely fails with the errors in my last post (I have verified this).  But if you run wireless-KERNEL *after* you load my extension, then you get the tainted kernel warnings but wireless-KERNEL does load the firmware (and you are then able to use wifi).

firmware-rtlwifi doesn't seem to make a difference one way or the other.  This isn't surprising, as my code is really just a separate branch of rtlwifi_new that builds a different set of drivers in the same family as that package.

Interestingly, while loading wireless-KERNEL first and wifi-rtw88 second makes it so the firmware isn't loaded properly, it *does* get rid of the taint warnings.  Is it possible that mac80211.ko.gz from wireless-KERNEL is needed to prevent the taint warnings, but then wireless-KERNEL as a package needs the firmware loaded first before it can set up the drivers?  If so, this would create a circular dependency between the two packages that I'm not sure how to resolve.

I believe that the wireless driver for your hardware loads the firmware - you can check this in dmesg, for example:
Code: [Select]

Since you are not using a driver from wireless-KERNEL, it should be your RTL8822be driver that loads the firmware.

Post by: mrjake2 on March 04, 2020, 02:56:33 AM
Hi Juanito - it sounds like you are saying that i should be able to load wireless-KERNEL before my RTL8822be driver because wireless-KERNEL is not actually loading the firmware.  Am I understanding you correctly?  That's not quite what I'm seeing when I load wireless-KERNEL:
Code: [Select]
> tce-load -il wireless-5.4.3-tinycore64
platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

rtw_pci 0000:02:00.0: failed to load firmware

rtw_pci 0000:02:00.0: failed to setup chip information
rtw_pci: probe of 0000:02:00.0 failed with error -22

You can see above that it's failing because it is looking for rtw88/rtw8822b_fw.bin and not finding it - that's because that is the directory and firmware file that my driver code loads.

But if load my driver first and then wireless-KERNEL, I get the taint messages followed by the firmware being loaded as expected:

Code: [Select]
> tce-load -il wifi-rtw88
rtw88: loading out-of-tree module taints kernel.
rtw88: Unknown symbol ieee80211_start_tx_ba_cb_irqsafe (err -2)

rtw_pci 0000:02:00.0: Firmware version 27.2.0, H2C version 13

I'm not 100% clear what wireless-KERNEL does, but from the above it looks like it finds and uses (or maybe sets up) Firmware version 27.2.0, H2C version 13.  But it only does that if I load wifi-rtw88.tcz first.

From the look of your dmesg output, the kernel believes that the rtw88 driver in wireless-KERNEL is the correct one for your hardware.

rtw8822b_fw.bin is in firmware-rtlwifi

Have you tried loading firmware-rtlwifi then wireless-KERNEL and seeing if things work (all without loading your driver)?

Try it with the dependencies in the order listed. If that doesn't work, you may have to break out your firmware into a separate
extension (firmware-rtl8822be.tcz). Then use a dependency file that looks like this:
Code: [Select]
firmware-rtl8822be.tcz

Yes, that was the first thing I tried, and it still complained about not being able to find rte88/rtl8822be.bin. That was why I compiled my own driver in the first place. Once I compiled my own driver then wifi started work, just with the taint errors on load.

Is that an exact quote? Because  firmware-rtlwifi.tcz.list  lists the firmware files name as:

The way wifi firmware loading works is that the kernel first tries to load the firmware from the driver itself and, if that fails, it tries to load the firmware from /usr/local/lib/firmware.

Looking at your dmesg output:
Code: [Select]
rtw_pci 0000:02:00.0: Direct firmware load for rtw88/rtw8822b_fw.bin failed with error -2
rtw_pci 0000:02:00.0: Falling back to sysfs fallback for: rtw88/rtw8822b_fw.bin
rtw_pci 0000:02:00.0: Firmware version 27.2.0, H2C version 13..this is what seems to have happened.

You could try editing wireless-KERNEL to remove /usr/local/lib/modules/5.4.3-tinycore64/kernel/drivers/net/wireless/realtek/rtw88/rtw88.ko.gz and try again loading firmware-rtlwif then the modified wireless-KERNEL and finally your driver.

For what it's worth, when trying to get my wireless working on another distro (I believe it was Kali) I had the exact same problem with that driver.  In that case someone had already recompiled the same one that I have compiled, but for Kali.  Dropping that in resolved the issue for me.  So I'm pretty confident that the existing driver really no longer works given that this was a required change in that distro as well.

Hi mrjake2
According to your  dmesg,  it's looking for  rtw8822b_fw.bin.  That file is listed here:

http://tinycorelinux.net/11.x/x86_64/tcz/firmware-rtlwifi.tcz.list

That's true, but when I try to load firmware-rtlwifi followed by wireless-KERNEL, it doesn't work.  I get the errors posted above.

However, I did notice that firmware-rtlwifi.tcz puts it in a different directory than the one I get in the error message.  firmware-rtlwifi.tcz puts it in rtlwifi/rtw8822b_fw.bin, but my updated firmware from the rtw88 branch of https://github.com/lwfinger/rtlwifi_new/tree/rtw88 puts them under rtw88/rtw8822b_fw.bin instead.  This exactly matches the dir that I see in the error message, so as a test I created rtw88/ under firmware/ and copied the driver from the firmware-rtlwifi.tcz package to that new dir.  Strangely, this got rid of the "failed to load firmware" error messages, but it also didn't result in seeing the line "Firmware version 27.2.0, H2C version 13", which I believe would mean that the driver was loaded correctly. 

After doing this I loaded wifi.tcz, started X, and tried to run wifi.sh.  It does find wlan0, but it never completes a successful wifi scan.  So I think the driver is in the correct location at this point, but the driver itself isn't correct anymore.  Based on the instructions I see in the README for https://github.com/lwfinger/rtlwifi_new/tree/rtw88 - plus the fact that I've only been able to get this to work when I use the compiled code for that branch, and that I needed the drivers compiled from this same branch to get wifi working in Kali Linux - I believe that I need to be using the version of rtw822b_fw.bin that I compiled, and that it needs to be in rtw88/ instead of rtlwifi/.  I just don't know how to get rid of the taint errors.

OK, forget about loading  firmware-rtlwifi.tcz  and  wireless-KERNEL.tcz

Unpack the driver extension you created.

Move the firmware from that extension into an extension called:

firmware-rtl8822be.tczAdd a file called:
Code: [Select]
/usr/loca/tce.installed/firmware-rtl8822bePlace the following in that file:

Then copy your firmware and driver extensions to your tce directory, then reboot and:

tce-load -i YourCompiledDriver.tcz

Maybe it was listed in your  onboot.lst?  You did reboot prior to trying to load it, right?

Sorry, I missed the part about rebooting.  But I did reboot by happenstance because I tried this several times.  Whenever I rebooted, the script in /usr/local/tce.installed disappeared though, so I needed to recreate it after every reboot.  Do I need to do something differently to make sure the script persists between reboots?

I also did check that it isn't listed in my onboot.lst.  The only thing in there is Xorg-7.7, and I have showapps on the linux kernel params to ensure that it wasn't being loaded as a dependency (it's not).

Got it.   So I changed that and some of the strange errors have gone away now.  However, I do still get the taint warnings when I load the drivers I compiled (not the firmware).  After that, though, wifi works as expected.

So to summarize, I get the following after each step:

So I guess what we learned from this is that the taint messages are coming from the drivers, not the firmware.  Not sure what to do with that information though.

Packaging the module to /usr/local/lib/modules is correct - the taint message comes from the module being out of tree/licensing issues.

Since your module moved from staging in kernel 4.x to being in-tree in 5.x, I'm surprised that the stock version does not work.

Looking here:

I don't see  rtl8822be  or any  8822  drivers listed. Or am I misunderstanding something?

Hi Juanito
Checking here:
http://tinycorelinux.net/11.x/x86_64/release/src/kernel/config-5.4.3-tinycore64

I see:
# CONFIG_RTL8XXXU_UNTESTED is not set
CONFIG_RTW88=m
CONFIG_RTW88_CORE=m
CONFIG_RTW88_PCI=m
CONFIG_RTW88_8822BE=y
CONFIG_RTW88_8822CE=y
# CONFIG_RTW88_DEBUG is not set
# CONFIG_RTW88_DEBUGFS is not set

If that's the driver for his hardware, it's built into the kernel. If that's true, does the firmware need to be built into the kernel too?

They are in an unexpected place but they are there:

tinycore64/kernel/drivers/net/wireless/realtek/rtw88/rtw88.ko.gz
./usr/local/lib/modules/5.4.3-tinycore64/kernel/drivers/net/wireless/realtek/rtw88/rtwpci.ko.gz

Those are the same names as the drivers that I compiled, however their location has changed to no longer be under Realtek. They are now just under wireless/rtw88/.
