Integrated Webcam Realtek Integrated_Webcam_HD (0bda:58f4) not working in DELL XPS 13 9370 with firmware 1.50

It seems that there is a patch being worked out:

https://<email address hidden>/msg127992.html

This change was made by a bot.

Another piece of information. This webcam is working with the 1.0 firmware, but not with the 1.5 firmware that the Dell XPS 13 9370 ships right now. Some affected user have reported the issue and they have changed the screen for them with a webcam with the 1.0 firmware, and the webcam started working.

This is the non-working firmware:

uvcvideo: Found UVC 1.50 device Integrated_Webcam_HD (0bda:58f4)

And this is the working one:

uvcvideo: Found UVC 1.00 device Integrated_Webcam_HD (0bda:58f4)

I tried the following upstream kernel:

Linux XPS-13-9370 4.17.0-041700rc1-generic #201804152230 SMP Mon Apr 16 02:33:40 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

and the bug is reproducible.

Dear Walter,
  that's interesting, thanks for digging this out. Is there any way we can use the firmware 1.00 instead of 1.50? For example swapping a file in /lib/firmware?

Thanks
Stefano

Dear Stefano, I think the problem is there is no appropriate driver in the Linux kernel for the 1.50 firmware, and the installed webcam has that firmware.

I'm trying now to recompile the 4.17.rc1 kernel with the patch I mention in #2. I will try this patched kernel and see if the webcam works.

I've tried with a 4.17rc1 kernel recompiled with the patch mentioned in #2 but no change, the webcam does not work.

Is the webcam firmware upgradable under Linux? I can't reproduce the issue on the XPS 9370 at my hand because it's with older firmware.

Kai-Heng Feng (kaihengfeng):

As far as I can tell the only way to upgrade the firmware is to completely change the screen, at least this is what Dell is doing for the users that report the issue. This is the new XPS 13 9370 laptop that they started selling at the end of January 2018. And instead of upgrading, they downgrade from version 1.50 to 1.00.

Please try this kernel,
https://people.canonical.com/~khfeng/lp1763748/

I made an ugly workaround to keep the UVC version at 1.0. Let's see if this work.

Thanks Key-Heng, I tried your kernel but in my system there is no change. The webcam is still using the 1.50 firmware and is not detected by the system.

Dear Kai-Heng
  thank you vefry much for your contribution. I do have a webcam version
15.0
  I (think I) installed your .deb and rebooted and this is what I see in
the journal:

   It looks (to me) that the version 1.50 is still detected by the kernel.
Two questions:
   a) how can I make sure I am running your version (the uname -r is the
same...)
   b) is there any other output you would like to see?

  P.S. needless to say the webcam is not working ATM :-)

Thanks
Stefano

Ok, I use a more direct way to force the version to be 1.0:
diff --git a/drivers/media/usb/uvc/uvc_driver.c b/drivers/media/usb/uvc/uvc_driver.c

Here's the kernel:
https://people.canonical.com/~khfeng/lp1763748-2/

I tried this last one, and webcam still not detected. But now syslog seems to show the 1.00 firmware. This is the output of "dmesg | grep uvcvideo":

 dmesg | grep uvcvideo

Right, I wasn't give it too much hoping.
I'll escalate the issue to UVC upstream to let them know the issue.
I'll also ask Realtek if there's a way (maybe via USB control message) to switch between UVC1.0/UVC1.5.

@Kai Heng,

I believe this should help:

Can you please apply https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/media/usb/uvc?h=v4.17-rc1&id=e96cdc9a0aa2fcaa276a76e8ffa86fc10a1d3d99 to a test kernel?

Or alternatively can someone affected please test 4.17-rc1 (it's included)?

As I say in message #5, I tried 4.17rc1 and the webcam was still not working.

I actually found the discussion [1] several days ago. The patch is to support a new format.
The webcam in [1] is the UVC1.0 variant.

OTOH, this bug is not about format, the error happens at driver probing.

[1] https://www.spinics.net/lists/kernel/msg2755810.html

If the firmware is downgrade-able, I guess the best option here is to ask users to downgrade the firmware via fwupdmgr?

See this forum:

https://www.dell.com/community/Linux-General/Dell-xps-13-9370-Webcam-support/td-p/6032049

Dell is downgrading the firmware by plainly substituting the whole screen with another screen that has the integrated webcam with firmware 1.00.

@Walter Garcia-Fontes,

Sorry, I missed that comment of yours. Thank you for confirming that 4.17-rc1 didn't adequately resolve the issue.

I believe what this is coming down to is that there are still aspects from UVC 1.5 that are missing in the kernel then.

@Kai Heng,

There is no plugin currently available for fwupdmgr that can downgrade this firmware currently.

Let's wait for maintainers' reply for [1].

I Cc'ed both of you.

[1] https://www.spinics.net/lists/linux-media/msg132364.html

I am no kernel expert so, will leave that to those of you who are qualified. I did find this interesting. I am experiencing all of the same symptoms but, when I spin up a Windows instance in Virtualbox on 17.10 host, the camera is available and it works. Not sure how to explain that but, it does tell me that the camera is actually functionable.

@jay-z The reason is quite simply that there are drivers for this webcam available for Windows but not for Linux.

A solution has been proposed by Dell France:

http://dl.free.fr/uYeYUDXjo

Untar the archive and then go inside the folder, and you should be able to execute: sudo ./rts_uvc -v 0x0bda -p 0x58f4 --download 170606_6BF129N2_58F4_v7605.rfw

It should say a huge "PASS" and after rebooting the camera should be working.

I haven't been able to try it yet because I don't have my laptop with me.

Here is the reference:
https://www.dell.com/community/Linux-General/Dell-xps-13-9370-Webcam-support/td-p/6032049/page/9

HUGE Thanks!
I can confirm that this solution works perfectly for my laptop (for the record: you do not even need to reboot).

Many thanks too !!!
Works perfectly.
Also no need to reboot.

Just to share, here is the output of the script:

More comments coming from DELL:

"Yesterday, a new Dell internal document was created which contained a temporary work around to downgrade the camera firmware to 1.0 ( the file RomainDurritcague shared ). This internal document is about to be deleted as this fix wasn't meant to be shared yet. The document was released prematurely. I've asked RomainDurritcague to delete the post which contains the file in question. The firmware downgrade is a downgrade in features. We don't like to downgrade our customers.
Dell is working to release an OS patch that will allow Ubuntu owners to utilize the camera with UVC 1.50. The patch is scheduled to be released on 5/11. That's all the detail
I have on the patch at this time. More to come.

All,

The patch has been submitted here:

https://lkml.org/lkml/2018/5/8/1117

@Kai Heng,

Can you share a test kernel with that patch for folks in this thread affected?

Hello,
  I am with the few who tried the downgraded firmware 1.0
  Would it be possible to release the firmware 1.5 for us to re-upgrade?

Thanks
Stefano

I built a kernel with the patch. Please try it here.
https://people.canonical.com/~khfeng/lp1763748-rtl/

Some steps to install the kernel on https://people.canonical.com/~khfeng/lp1763748-rtl/.

1. Download all Debian packages from https://people.canonical.com/~khfeng/lp1763748-rtl/

2. Open a GNOME Terminal by Ctrl+Alt+t.

3. Execute the following command in GNOME terminal to check if all Debian packages are already here to install.

$ ls -l ~/Download/

4. Execute the following command in GNOME terminal to install the kernel

$ sudo dpkg -i Download/linux*.deb

5. Reboot the system to use the new kernel.

P.S. If you want to remove the testing kernel, just execute `sudo apt purge linux-headers-4.15.0-22 linux-headers-4.15.0-22-generic linux-image-unsigned-4.15.0-22-generic linux-modules-4.15.0-22-generic linux-modules-extra-4.15.0-22-generic`.

Hello! I have compiled kernel module with patch from https://lkml.org/lkml/2018/5/8/1117 and I can confirm it works. I'm attaching related lines from dmesg. Module was loaded via insmod. I'm using 4.16.1 Kernel.

@Josef,

Glad to hear that confirmation. It may be useful to respond with a Tested-by to the patch upstream.
https://patchwork.kernel.org/patch/10388043/

@Stefano

No need to upgrade again. You can stay at 1.0 and it's functionally just fine with Ubuntu.

Thanks,

@Mario
Well, 1.0 already works without any patch. It'just downgraded in features too, right?

S

Only if you have userspace that uses other 1.5 features, which doesn't
exist today in Linux. The patch and fw 1.0 should be functionally
equivalent for Linux.

I finally could get back to my laptop, and I have tried Kau-Heng's patched kernel 4.15.0-22 . I confirm that the webcam now works as expected. Thanks a lot Kay-Heng and Mario.

I will apply now for a SRU for all supported Ubuntu versions.

@Mario Tested-by submitted to upstream. Thanks for this hint!

Ok for Xenial (v4.4) kernel, there's one missing commit that adds UVC1.5 to device ID.

The commit for this bug is still needed though.

I'll send another SRU to backport the commit.

well. I have just tested the proposed kernel (*) for 16.04. strangely my camera is not seen at all, there is not trace of any "UVC" activity in syslog/dmesh, and when I load the module "by hand" it does not detect any camera. only lsusb does. Am I still missing something?

[4.4.0-128-generic #154], maybe this is wrong?]

Well, you are not wrong. There's one missing commit for Xenial. I've already filed LP: #1773905 for that.

Ok thanks, sorry. Now I understand the meaning of your message #47. I'll wait.

PS : I tried the "hwe" 16.04 kernel (which is the kernel from 17.10) and it does not work either...

"Proposed" needs to be enabled in APT to use the new kernel.
