Error when loading intel-ipu6 module

I am running 5.19.12-1-default on OpenSUSE Tumbleweed. My hardware is LENOVO 21CBCTO1WW/21CBCTO1WW, BIOS N3AET65W (1.30). I got an error when loading intel-ipu6 module (commit from 20220926) during boot:

Edit: Still the same problem with kernel 6.0.0 and the commit from 20221009

I can confirm the null pointer dereference in ipu_pci_probe as well, same BIOS, slightly different laptop configuration, on Debian Bookworm/Sid, happens on kernels 5.18, 5.19 and custom compiled 6.0-rc.

For me, it has the nasty side effect that shutdown and suspend are broken afterwards.

My wild guess is that it has to do with the patch int3472-support-independent-clock-and-LED-gpios-5.17+ included in this repo is not applied with dkms builds, and furthermore, it does not contain entries for the X1 Carbon:

 };

I guess there some entry for the X1 Carbon (which I also have) is necessary!?

Seing this null pointer dereference with the patch int3472-support-independent-clock-and-LED-gpios-5.17+ included.

@fhloston On which hardware?

Btw, I tried with the new kernel: ~~Error seems to be gone after power off/on of the system and after installing 6.0.0-060000-generic. There is this, not sure what it means, or if it is important: RIP: 0010:ipu_pci_probe.cold+0x404/0x904 [intel_ipu6]~~

Same error for kernel 6.0 and 6.1rc1 (dmesg_ipu6.txt)

Camera/shutdown/standby not working, but maybe related to other issues with the a370m Intel driver, as the whole dmesg output looks like a Christmas tree

Thanks for your suggestion. I tried it out, but seems to generate the same error. This is the dmesg output, in case it can be useful: 5.19.0-9021-generic_dmesg.txt

The point is, I tried something crazy, I merged the driver with the current next branch (development branch). It was a little bit tricky, as the interface changed even more (it seems media entities had previously only one pipeline. But in the new kernel they have multiple pods that can have a pipeline each. A compatibility function exists that goes through all pods and returns the first pipeline that it can find. As it is assumes that usually there is only one pipeline involved. I changed the code to call this utility function. Also I looped through the pods to find the pipeline during closing/deinitalization. But I only close only the first as in the utility function. As I assume that the camera driver only uses one pipeline, I have no idea if this is ok?) This is the full diff between kernel branch next-20221019 and the integrated/modified driver in my local branch: gitdiff-kernel.txt Kernel compiles but still has the same error! To regenerate the next-kernel something like this should work:

git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git  
cd linux  
git remote add linux-next https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
git fetch linux-next
git fetch --tags linux-next
git checkout master
git remote update
git checkout -b hp_spectre_i7-1260p next-20221019
git apply <insert ~/Download/ or where the file is>gitdiff-kernel.txt

Then you have to add the .config file, mine was this: config.txt Then, to build the kernel:

make -j 12
make deb-pkg LOCALVERSION=-ipu6mod -j 12

After this you can install the kernel:

cd ..
sudo dpkg -i linux-libc-dev_6.1.0-rc1-next-20221019-ipu6mod-1_amd64.deb
sudo dpkg -i linux-image-6.1.0-rc1-next-20221019-ipu6mod_6.1.0-rc1-next-20221019-ipu6mod-1_amd64.deb

But I was looking through the diffs and saw that the camera driver files are most probably not in the latest version of the ipu6 repository, i will try to change this and see what happens. (not sure if the ipu driver was already loading the camera driver while it got stuck with the error, or if it was still in an earlier state).

In case I find something out I will post it. Actually, I am not familiar with kernel development and the media subsystem in particular, I actually not even have a clue what the pipeline (image stream from senor to memory, I assume) & pods are, so I am not certain if my modifications for the next-20221019 are ok, but maybe it can be useful for someone.

The specific crash mentioned here is fixed by: https://github.com/intel/ipu6-drivers/pull/58/commits/5a36712499e83cdf1ec6b89e13df573e09ebe565

But fixing it just results in somewhat related crashes further down the road, note I have fixes for those too, see #58 in general. But you also need some other changes to get things to actually work on Alderlake Lenovo Thinkpads let me copy and paste my comment from #55 about this:

I have been working on making the ipu6-driver stack work on a Lenovo Thinkpad X1 Yoga gen 7 (alderlake) with a 6.0 kernel and using the INT3472 mainline kernel driver for power-control.

I have submitted the following fixes for this, I believe these should also fix things not working on the X1 Nano Gen2:

https://github.com/intel/ipu6-drivers/pull/58 https://github.com/intel/ivsc-driver/pull/24 https://lore.kernel.org/linux-acpi/20221022150722.31787-1-hdegoede@redhat.com/

Note this relies on the mainline kernel itself also being build with the 2 patches from ipu6-drivers/patch. And if you look at the int3472-support-independent-clock-and-LED-gpios-5.17+.patch you will see it adds an entry for the Yoga Gen 7 to the int3472_sensor_configs[] table. You may need to add a copy of that entry with the sensor-module-name used for the main camera on your model. Note the IR camera is not supported yet.

I can confirm that applying the before mentioned fixes i can see video from the webcam for the first time!

Thank you, great job @jwrdegoede

sudo -E gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink

Sadly v4l2-relayd does not work for me yet.

@jwrdegoede how do you then use the camera?

@jwrdegoede how do you then use the camera?

I have not gotten around to trying v4l2-relayd yet. I was happy to have gst-launch work after a marathon coding session involving all the kernel fixes and then called it a day :) I might give v4l2-relayd a shot coming Tuesday.

BTW did you have to add an entry to the int3472_sensor_configs[] table ?

BTW did you have to add an entry to the int3472_sensor_configs[] table ?

I looks like that I do not need to add an entry to int3472_sensor_configs[] for the HP Spectre x360 16-f1010TX (i7-1260P)

I compiled the kernel now with all patches applied, seems that I am almost there :)

This looks to me as if there are some HAL-driver related files missing, but it seems that the device is available.

same for the other command: sudo -E gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesin

Btw, is there any easy way to list the acpi ensor-module-names in the console?

BTW did you have to add an entry to the int3472_sensor_configs[] table ?

No, I just applied your mentioned patches plus an unrelated i915 patch. Also X1 Yoga gen7 here.

@fhloston was that i915 patch useful?

@jeffreyfq There are multiple names that are necessary for sensor setup.

The _HID and _DDN from ACPI can be obtained easily and are used in the camera sensor driver. On my X1 Yoga Gen 7, the cameras have HIDs like INT3474 and that name can be found in drivers/media/i2c/ov2740.c. Script to find these (needs acpica-tools for iasl):

cat /sys/firmware/acpi/tables/DSDT > dsdt.dat
iasl -tc dsdt.dsl
grep -A9 "Device (CAM" dsdt.dsl

Then there is a model string from ACPI _DSM() of some device that is used by int3472 and compared to the list in int3472_sensor_configs[].

Maybe it is contained in the DSDT, but not verbatim, so I just added dev_info(int3472->dev, "Sensor _DSM: %s\n", obj->string.pointer); to skl_int3472_get_sensor_module_config(...) and saved the work of figuring out where that string ultimately comes from.

As a sort of long shot I added this to int3472_sensor_configs[]

    /* Lenovo ThinkPad X1 Yoga Gen7 - OV9234 monochromatic sensor? */
    { "6BF115T2", { 0 }, NULL, true },

and changed ov9734_acpi_ids[] in drivers/media/i2c/ov9734.c to

    { "OVTI9234", },
    { "OVTI9734", },
    { "INT3471", },

but the ov9734 sensor driver does not like its monochrome sibling variant and fails with -EINVAL during probing. No crash though.

@jeffreyfq There are multiple names that are necessary for sensor setup.

Thank you for your help and the detailed instructions, I was able to read out the ACPI data:

        Device (CAM0)
        {
            Name (_HID, "INT3471")  // _HID: Hardware ID
            Name (_DDN, "IMX135-CRDG2")  // _DDN: DOS Device Name
            Name (_UID, "0")  // _UID: Unique ID
            Name (_DEP, Package (0x01)  // _DEP: Dependencies
            {
                PMIC
            })
            Name (_PLD, Package (0x01)  // _PLD: Physical Location of Device
--
        Device (CAM1)
        {
            Name (_HID, "INT3474")  // _HID: Hardware ID
            Name (_DDN, "OV2740-CRDG2")  // _DDN: DOS Device Name
            Name (_UID, "0")  // _UID: Unique ID
            Name (_DEP, Package (0x01)  // _DEP: Dependencies
            {
                ^^I2C2.PMIC
            })
            Name (_PLD, Package (0x01)  // _PLD: Physical Location of Device

So I have the device INT3474 with OV2740-CRDG2 and a device INT3471 with sensor IMX135-CRDG2.

It seems that OV2740 and IMX135 (for imx135 there is seemingly no driver available in drivers/media/i2c/), both are RGB sensors, kind of strange, I thought the IR sensor would be grayscale.

Then I checked, the driver should be fine, there is my _HID name INT3474 in the driver structure ov2740_acpi_ids already.

So next I will compile the kernel module with some print statements to get the _DSM name to add it to the int3472_sensor_configs[]

I still have the _DDN name, do I have to add this name also somewhere? Or is it just relevant to figure out which driver/sensor type it is (e.g. in my case OV2740)?

I did it: Mine is

[    5.480086] int3472-discrete INT3472:01: Sensor _DSM: CJFKE26
[    5.486444] int3472-discrete INT3472:02: Sensor _DSM: CJFKE26

for HP Spectre x360 16-f1xxx (i7-1260P, igpu+ dgpu a370m)

Update: I booted now with the modified kernel modules. Dmesg tells me this now:

[    5.181779] systemd-journald[492]: Received client request to flush runtime journal.
[    5.254716] intel_skl_int3472_discrete: loading out-of-tree module taints kernel.

[    5.264893] int3472-discrete INT3472:02: error -ENODEV: Failed to map regulator to sensor

Update2: I figured out that the error No supply name defined is caused because the entry in int3472_sensor_configs has to include some definition like e.g. REGULATOR_SUPPLY("avdd", NULL), like this:

...
/* HP Spectre x360 16-f1xxx */
{ "CJFKE26", REGULATOR_SUPPLY("avdd", NULL), NULL, true },
...

Actually I dont know what the fourth argument -true- means, did not try with false yet.

Now something happens, but also new errors appear and also the dmeg is messy (includes intel vsc not ready):

I loaded the v4l2 loopback kernel module as well. There are even video devices /dev/videoX, but they dont work as well. So it looks like almost, I guess I may have to recompile everything from scratch, to make sure I did not mess anything up with all the modifications and the kernel version. But for now I may give up :D

@fhloston was that i915 patch useful? @drogenlied yes, trace is gone after applying it (https://gitlab.freedesktop.org/drm/intel/-/issues/6592)

You seem to have another secondary sensor in your X1 Yoga Gen7 than me:

` Device (CAM0) { Name (_HID, "INT3471") // _HID: Hardware ID Name (_DDN, "IMX135-CRDG2") // _DDN: DOS Device Name Name (_UID, "0") // _UID: Unique ID Name (_DEP, Package (0x01) // _DEP: Dependencies { PMIC }) Name (_PLD, Package (0x01) // _PLD: Physical Location of Device

    Device (CAM1)
    {
        Name (_HID, "INT3474")  // _HID: Hardware ID
        Name (_DDN, "OV2740-CRDG2")  // _DDN: DOS Device Name
        Name (_UID, "0")  // _UID: Unique ID
        Name (_DEP, Package (0x01)  // _DEP: Dependencies

            ^^I2C2.PMIC
        })
        Name (_PLD, Package (0x01)  // _PLD: Physical Location of Device`

Sorry for weird formatting :/

Seems my X1 Yoga Gen7 has the same camera setup like @jeffreyfq 's HP Spectre x360.

@jeffreyfq have you tried setting the device name explicitly with: sudo -E gst-launch-1.0 icamerasrc device-name=ov2740-uf buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink

@fhloston I just tried now, but results in the same error. But considering that my hardware is so similar to the X1 Yoga Gen7, like in your case, I guess it has to work for me too. I guess to be on the safe side, I have to start over and patch the kernel/modules from a fresh checkout, could be possible that I messed up something.

this is the output (does not cause new dmesg errors):

@jeffreyfq This is the same error I have with the OV2740 in the Nano X1 Gen2 that I've filed a bug report on ( #55 )

I haven't been able to get further than you and like you I'm a little fatigued by it. I do have one tidbit of info though. Launching your gstreamer command with GST_DEBUG env var set can get you a lot more information. Something like:

GST_DEBUG=4 sudo -E gst-launch-1.0 icamerasrc buffer-count=7 device-name=ov2740-uf ! video/x-raw,format=YUY2,width=1280,height=720 ! v4l2sink device=/dev/video1

I was tracking this down to missing modules or a conflict with the ivsc-driver package. dmesg | grep vsc doesn't produce any output for me however.

You seem to have another secondary sensor in your X1 Yoga Gen7 than me

Note that the presence of the sensor in the DSDT does not say everything, there are multiple sensor entries and only some actually are "active", this is governed by the _STA method of the ACPI device returning 0xf (present) or 0 (not present).

To really see which sensors you have, first build the main kernel with the int3472-gpio + https://lore.kernel.org/linux-acpi/20221022150722.31787-1-hdegoede@redhat.com/ patches. After this the sensors should show up under in ls /sys/bus/i2c/devices for me the 2 sensors are i2c-INT3474:01 which is the ov2740 normal sensor and i2c-OVTI9234:00 which is an ov9234 monochrome sensor which is used as ir-sensor here.

@fhloston What does dmesg | grep vsc say for you when it's working? Can you give a set of outputs, the v4l2 camera information and dmesg | grep ipu and lsmod | grep 'ipu|mei|vsc'. Would be very helpful <3

I did however blacklist intel-ipu6 in /etc/modprobe.d/ipu6.conf because in the boots after installation the system would crash. To my astonishment it then works even though blacklisted. So I assume there still is an issue with module loading order.

To really see which sensors you have, first build the main kernel with the int3472-gpio + https://lore.kernel.org/linux-acpi/20221022150722.31787-1-hdegoede@redhat.com/ patches. After this the sensors should show up under in ls /sys/bus/i2c/devices for me the 2 sensors are i2c-INT3474:01 which is the ov2740 normal sensor and i2c-OVTI9234:00 which is an ov9234 monochrome sensor which is used as ir-sensor here.

yes, indeed! thanks!

@fhloston thank you for taking the time to write these out, very helpful. I'll get to this sometime today.

Just something I noted while applying the kernel patch of @jwrdegoede , in drivers/acpi/scan.c, there is an ignore and honor list:

/* List of HIDs for which we honor deps of matching ACPI devs, when checking _DEP lists. */
static const char * const acpi_honor_dep_ids[] = {
    "INT3472", /* Camera sensor PMIC / clk and regulator info */
    NULL
};

My devices are named INT3471 and INT3474, so I am currently compiling the kernel with those two device names added to the list. Not sure if this is necessary, but later in the code:

bool acpi_dev_ready_for_enumeration(const struct acpi_device *device)
{
    if (device->flags.honor_deps && device->dep_unmet)
        return false;

    return acpi_device_is_present(device);
}

maybe the driver is never loaded if the device name is not in this honor list....

@fhloston : did you forget the IOMMU-passthrough-for-intel-ipu.diff patch in you previous post/while patching the kernel?

As I obviously developed an obsession of compiling my kernel, I tried another round.

This time, I used kernel 6.0.5, downloaded from kernel.org. I applied all the patches in the order @fhloston mentioned in the previous post.... ..except... :) I applied additionally IOMMU-passthrough-for-intel-ipu.diff I added my ids to the int3472_sensor_configs, like so:

/* HP Spectre x360 16-f1xxx */
{ "CJFKE26", REGULATOR_SUPPLY("avdd", NULL), NULL, false },

Actually I tried true and false as the last parameter, and false seems to work better somehow^^ I also added my _HID IDs to the struct acpi_honor_dep_ids.

Then it seems to be crucial to install the v4l2loopback kernel module.

Somewhere in the internet, someone mentioned v4l2-relayd, so I installed it... just in case it does something useful.

As it turns out, I am getting same error messages as before on my self-modified 6.2-rc2/next kernel.

The only related dmesg errors show this:

1.388599] intel vsc not ready
[   16.714727] hp_wmi: Unknown event_id - 131073 - 0x0 <-- this is just the keyboard
[   18.036145] intel vsc not ready
[   18.037633] i2c i2c-INT3537:00: deferred probe pending

I am not sure, but I had a look into the source, the intel vsc not ready orignates in ipu6-drivers-0.0.0/drivers/misc/ivsc/intel_vsc.c and the related source is:

    ret = check_component_ready();
    if (ret < 0) {
        pr_info("intel vsc not ready\n");
        return -EAGAIN;
    }

and the check_component_ready function is doing something like this:

...
if (vsc.ace_registerred && vsc.csi_registerred)
        ret = 0;
...

so it will not be ready until mei_csi.c and mei_ace.c call their respective functions vsc_register_csi(csi, &csi_ops); and vsc_register_ace(ace, &ace_ops); that are located in the module probe functions.

I even put some additional print-outs there, and it turns out those modules are listed in lsmod, but their probe function is never called!! Not sure how this is possible, I thought when I modprobe the module the probe function is called... but my guess is that there is some fancy function in the kernel which relates to the i2c i2c-INT3537:00: deferred probe pending message in the dmesg (not sure).`, maybe some module probe is pending?

One thing that seems strange to me is that there is a hi556 kernel module loaded, even though I dont have this sensor in my device (according to this acpi information)! This could be related to why it is not working. There is no OV2740 module.

@jeffreyfq checkout #55 and read a bit. There's some helpful things in there, does /dev/ipu* exist?

What is in /sys/bus/i2c/devices/??

Did you actually apply the "LATT2021" patch from the kernel mailing list? Copied manually?

What happens when you modprobe ov2740?

Here is what a working GPIO/i2c dev tree looks like for the ov2740 sensor on a nano gen2:

@jeffreyfq you should not edit/change acpi_honor_dep_ids. To make the i2c devices for the sensors show up under /sys/bus/i2c/devices you need 2 changes:

My patch which adds "LATT2021" to acpi_ignore_dep_ids[]
https://github.com/intel/ivsc-driver/pull/24/commits/c5aa0b65a6fb3cca7ee3b6fae093cfadfdd3a5cf

For details for how this all actually works (it has to do with ensuring that things are probed in a certain order) see: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9d9bcae47fd5a

@jwrdegoede That's exactly the details I wanted. Very great reading/learning material. Thanks.

@fhloston @jwrdegoede If you have trouble with v4l-relayd not working, try using v4l2loopback from Ubuntu (https://git.launchpad.net/ubuntu/+source/v4l2loopback), it contains patches (in folder debian/patches) that are crucial to make v4l-relayd work, mostly relating to V4L2_EVENT_PRI_CLIENT_USAGE, aka v4l2 events needed to start the stream when a client opens the loopback device.

I just got that to sort of work today with chromium and gstreamer video source, everything else has some problems with the loopback device and sometimes v4l2-relayd just crashes.

@drogenlied a thanks, that probably explains why it is not working for me.

Another tip: applying https://github.com/umlaeute/v4l2loopback/pull/435 to v4l2loopback will allow some ffmpeg based applications to use the device, otherwise they complain about buffer sizes. Maybe this just fixes symptoms and the root cause is somewhere in gstreamer, it helps nonetheless.

One more thing:

I added an output video format to the v4l2-relayd .service file and the config file, as shown below, now I have successfully tested Chromium, OBS, Firefox, mpv and VLC.

Especially VLC and Firefox really do not like the NV12 video format and work fine with YUY2.

Thanks @jwrdegoede and @polair for following up on this,

@jwrdegoede, I can confirm,

I now removed the the IDs I added to the acpi_honor_dep_ids struct.
The patch which adds LATT2021 to acpi_ignore_dep_ids[] was applied-> one liner + "LATT2021", / Lattice FW Update Client Driver / (But I dont have this LATT2021 device in my system)
I applied https://github.com/intel/ivsc-driver/pull/24 / (probe order fixes) and also the #58
I2C devices seem to be available (listing below; /sys/bus/i2c/devices/)
Of course, I also applied the gpio and IOMMU patches

@polair:

does /dev/ipu* exist?

Yes

Did you actually apply the "LATT2021" patch from the kernel mailing list? Copied manually?

Yes, I patched this, the one-liner, but I dont have that device in my system. I also applied the IOMMU, gpio, #58 and the 24 pull request (https://github.com/intel/ivsc-driver/pull/24)

What is in /sys/bus/i2c/devices/??

What happens when you modprobe ov2740?

Nothing, no dmesg entry, no error, I can not notice any difference after loading the module by hand.

I guess there are some differences to the HP spectre notebook, compared to the lenovo one. When I boot, the hi556 module is loaded and the ov2740 is not loaded. also the mei_vsc module is not loaded. There other modules are loaded.

But there is no hi556 device, also the device name in hi556.c:

static const struct acpi_device_id hi556_acpi_ids[] = {
    {"INT3537"},
    {}
};

Does not exist in the ACPI data (e.g. grep -A9 "INT3537" dsdt.dsl or grep -A9 "556" dsdt.dsl)

grep -A9 "(CAM" dsdt.dsl 
        Device (CAM0)
        {
            Name (_HID, "INT3471")  // _HID: Hardware ID
            Name (_DDN, "IMX135-CRDG2")  // _DDN: DOS Device Name
            Name (_UID, "0")  // _UID: Unique ID
            Name (_DEP, Package (0x01)  // _DEP: Dependencies
            {
                PMIC
            })
            Name (_PLD, Package (0x01)  // _PLD: Physical Location of Device
--
        Device (CAM1)
        {
            Name (_HID, "INT3474")  // _HID: Hardware ID
            Name (_DDN, "OV2740-CRDG2")  // _DDN: DOS Device Name
            Name (_UID, "0")  // _UID: Unique ID
            Name (_DEP, Package (0x01)  // _DEP: Dependencies
            {
                ^^I2C2.PMIC
            })
            Name (_PLD, Package (0x01)  // _PLD: Physical Location of Device

Also there is no LATT2021 device, checked grep -A9 "LATT2021" dsdt.dsl, can it be that the device has another name in my system, is there a way to figure this out? I guess the suspicious devices are:

But even then, I seems strange to me that the hi556 module loads without a device present in my system.

Right after boot, I can see many messages intel vsc not ready and one message i2c i2c-INT3537:00: deferred probe pending in the dmesg output.

@jeffreyfq the ACPI tables unfortunately are not always written in such a way that they are easily readable. E.g. the ACPI hw-id (HID/CID) may come out of a variable set by the BIOS.

E.g. you say there is no INT3537 in your DSDT (did you also check the SSDTs?) but since you do have a i2c-INT3537:00 device you clearly have an ACPI device in your tables with a INT3537 HID and this is also why the hi556 module is loading.

It is also interesting to see if the driver is actually binding to the device. Can you do:

ls -l /sys/bus/i2c/devices/INT3537:00/

And see if there is a driver symlink in there ? And the same for the other i2c-devices.

Note that it might be tricky to get things to work on laptop models which do not have an officially supported Linux OS option (typically an Ubuntu OEM install) . On these laptop models some extra work / fixes may be necessary and it may be quite tricky to figure out what changes are necessary.

Can you attach a full dmesg output from after your latest attempt here? And also please run sudo acpidump -o acpidump.txt and attach the acpidump.txt file here. Or send them both to me directly at hdegoede@redhat.com. Note I'm not making any promises here, but I can at least take a quick look. Also I'm quite busy this week so it may be a while before I get back to you.

@jeffreyfq Also please run: cat /sys/bus/i2c/devices/INT3537:00/firmware_node/path and let us know what the output is? This will tell us which "Device (NAME0000) {}" in the ACPI tables corresponds to the hi556 sensor. Typically a "Device (LNK0) {}" entry in the tables belongs to the main sensor.

Hi all,

[success message]

just joining in with a different but similar hardware: Lenovo ThinkPad X1 Carbon Gen 10, model 21CBCTO1WW

I got the webcam working with the following steps:

get kernel 6.0.6 (latest linux-stable)
patch with int3472-support-independent-clock-and-LED-gpios-5.17+.patch and IOMMU-passthrough-for-intel-ipu.diff
patch with LATT2021.patch
compile/install kernel
install ipu6-drivers with PR #58
install ivsc-driver with ivsc-driver-PR Number 24
install firmwares (via Arch packages intel-ipu6ep-camera-bin and intel-ivsc-firmware
install intel-ipu6ep-camera-hal-git
install icamerasrc-git
rebooted

With that in place I see a lot of log messages concerning IPU:

After that I managed to get a video output with

sudo -E gst-launch-1.0 icamerasrc device-name=ov2740-uf buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink

Next I will try relayd or loopback according to the comments here.

Thanks a lot for all your work

Additional information: With this repo: https://github.com/stefanpartheym/archlinux-ipu6-webcam and in particular the v4l2loopback and v4l2-relayd packages installed and loade using

modprobe v4l2loopback exclusive_caps=1

I get video output in MS Edge (Linux) in Jit.si and Google Meet.

Incredible!

@jeffreyfq the ACPI tables unfortunately are not always written in such a way that they are easily readable. E.g. the ACPI hw-id (HID/CID) may come out of a variable set by the BIOS.

E.g. you say there is no INT3537 in your DSDT (did you also check the SSDTs?) but since you do have a i2c-INT3537:00 device you clearly have an ACPI device in your tables with a INT3537 HID and this is also why the hi556 module is loading.

It is also interesting to see if the driver is actually binding to the device. Can you do:

ls -l /sys/bus/i2c/devices/INT3537:00/

And see if there is a driver symlink in there ? And the same for the other i2c-devices.

Note that it might be tricky to get things to work on laptop models which do not have an officially supported Linux OS option (typically an Ubuntu OEM install) . On these laptop models some extra work / fixes may be necessary and it may be quite tricky to figure out what changes are necessary.

Can you attach a full dmesg output from after your latest attempt here? And also please run sudo acpidump -o acpidump.txt and attach the acpidump.txt file here. Or send them both to me directly at hdegoede@redhat.com. Note I'm not making any promises here, but I can at least take a quick look. Also I'm quite busy this week so it may be a while before I get back to you.

@jwrdegoede Thanks, of course I understand if you don't have time for this. But in case you can have a quick look, and maybe find something I could check, it would be great.

E.g. you say there is no INT3537 in your DSDT (did you also check the SSDTs?) but since you do have a i2c-INT3537:00 device you clearly have an ACPI device in your tables with a INT3537 HID and this is also why the hi556 module is loading.

I now figured out, I don't have the ov2740 sensor. The camera is advertised as 5Mp and ov2740 is below that, I also booted windows and looked in the device manager. I have the hi556 sensor in my device!

This means that the loading of the kernel module is indeed ok. The entries shown by doing a grep -A9 "INT3537" dsdt.dsl on the dst table are obviously misleading and are not activated.

ls -l /sys/bus/i2c/devices/INT3537:00/

And see if there is a driver symlink in there ? And the same for the other i2c-devices.

There is a symlink:

Can you attach a full dmesg output from after your latest attempt here? And also please run sudo acpidump -o acpidump.txt and attach the acpidump.txt file here. Or send them both to me directly at hdegoede@redhat.com. Note I'm not making any promises here, but I can at least take a quick look. Also I'm quite busy this week so it may be a while before I get back to you.

dmesg output: dmesg.txt sudo acpidump -o acpidump.txt: There is a file-size limit, I will send the two files via e-mail

@jeffreyfq Also please run: cat /sys/bus/i2c/devices/INT3537:00/firmware_node/path and let us know what the output is? This will tell us which "Device (NAME0000) {}" in the ACPI tables corresponds to the hi556 sensor. Typically a "Device (LNK0) {}" entry in the tables belongs to the main sensor.

This is the path (I can see the same path in the windows device manager for the sensor)

jfq@jeffreyhp:~$ cat /sys/bus/i2c/devices/i2c-INT3537\:00/firmware_node/path 
\_SB_.PC00.LNK0

This is the output of gstreamer:

The first error is ERROR icamerasrc gstcamerasrc.cpp:2763:gst_camerasrc_set_caps: CameraId=0, StreamId=0 failed to config stream for format NV12 1280x720 but the stream format should be working according to instructions on https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api I also tried the native resolution of the sensor without success.

As a summary:

I have the Hi556 sensor
/dev/ipu-psys0 exists!
/sys/bus/i2c/devices/i2c-... devices exist and are symlinks
I don't have the i2c-LATT2021 device in my system!

I added this to the int3472 discrete.c:

/* HP Spectre x360 16-f1xxx */
{ "CJFKE26", REGULATOR_SUPPLY("avdd", NULL), NULL, false },

The sensor driver loads with this.

Ipu-related dmesg looks promising:

Later in the dmesg I get the following errors/messages that do not seem right:

intel vsc not ready

and

i2c i2c-INT3537:00: deferred probe pending

This tells me that there might be a dependency the vsc driver is waiting for. I added the latt2021 kernel patch, but I don't have the device. I tried to get a print-out of devices modules wait for. For this purpose I added the following to the drivers/acpi/scan.c to the acpi_scan_check_dep function at around line 1976:

....
        if (skip)
            continue;

        dep = kzalloc(sizeof(*dep), GFP_KERNEL);
        if (!dep)
            continue;

        count++;

        acpi_handle_debug(handle, "JFQ adding acpi _DEP device %s to device\n", info->hardware_id.string);    // <-- HRERE!!!!!!

        dep->supplier = dep_devices.handles[i];
        dep->consumer = handle;
        dep->honor_dep = honor_dep;

        mutex_lock(&acpi_dep_list_lock);
        list_add_tail(&dep->node , &acpi_dep_list);
        mutex_unlock(&acpi_dep_list_lock);
    }

    return count;
}

But I can not see any output in the dmesg of this, could be that there is no acpi device waiting or the acpi_handle_debug does not print to dmesg. Not sure, maybe this is the wrong place to check devices that hinder module loading.

Another thing I wanted to mention, during boot I can see the message:

[    5.409736] int3472-discrete INT3472:01: JFQ sensor name is i2c-INT3537:00 (discrete.c)
...
[    5.412935] int3472-discrete INT3472:01: GPIO type 0x12 unknown; the sensor may not work
[    5.412940] int3472-discrete INT3472:01: No clk GPIO. The privacy LED won't work
[    5.412942] int3472-discrete INT3472:01: JFQ probe return ok (discrete.c)

Modprobing works, but there is the message GPIO type 0x12 unknown; the sensor may not work, so there is a new GPIO type, I confirmed that INT3472_GPIO_TYPE_RESET, INT3472_GPIO_TYPE_POWER_ENABLE, INT3472_GPIO_TYPE_PRIVACY_LED are set. But No clk GPIO. The privacy LED won't work occurs as well.

My suspicion is that the new/unknown GPIO type 0x12 is maybe the physical lid of the sensor that can be closed opened by an electric mechanism (there is a key on the keyboard that physically closes/opens a lid in front of the camera lens). This is maybe why it is not yet defined in the driver. But it is just a guess for now.

I still fail to use /dev/video0 with vlc or firefox with v4l2loopback and v4l2-relayd

With vlc and trying to playback /dev/video0 at least the camera led turns on, but i see no picture. I see vlc detecting YUV format - even though i have set the format to NV12.

Any ideas what I could be holding wrong?

Update: OK, I have been holding it wrong, cheese and zoom just work. Update2: https://bugzilla.mozilla.org/show_bug.cgi?id=1761519

@fhloston as a workaround for the NV12 issue you can edit the v4l-relayd.service file, check my comment https://github.com/intel/ipu6-drivers/issues/48#issuecomment-1296241668

Maybe it is contained in the DSDT, but not verbatim, so I just added dev_info(int3472->dev, "Sensor _DSM: %s\n", obj->string.pointer); to skl_int3472_get_sensor_module_config(...) and saved the work of figuring out where that string ultimately comes from. (...) and changed ov9734_acpi_ids[] in drivers/media/i2c/ov9734.c

That's a very practical way to do it, but the solution may not scalable as you will only find the _DSM for the precise version of the camera you're using.

For example, the Nano has 2 different _DSM for each camera, depending if the screen is touchscreen enabled or not

/ Lenovo ThinkPad X1 Yoga Gen7 - OV9234 monochromatic sensor? / { "6BF115T2", { 0 }, NULL, true },

If you have access to the Windows partition, an alternative is to check the .inf files like:

/w11/Windows/System32/DriverStore/FileRepository/ov2740.infamd64 and /w11/Windows/System32/DriverStore/FileRepository/ov9234.infamd64

You will find there the names without much need to experiment:

OV2740:

4SF259T2
CJFLE23

OV9234:

0BG101N3
6BF115T2

but the ov9734 sensor driver does not like its monochrome sibling variant and fails with -EINVAL during probing. No crash though.

I think you may be requesting a resolution or a format that's not supported.

Check /win/Windows/System32/drivers/graph_settings_OV9234_6BF115T2_ADL.xml for supported formats, ex:

grep main.format /win/Windows/System32/drivers/graph_settings_OV9234_6BF115T2_ADL.xml
    <main format="YUV420_10_PL" width="640" height="384" />

I'm now here after opening #106.

Thanks for helpful comments.

            })

So I have what an Arducam IMX135?? lol

And OV2740-CRDG2 is Omnivision OV2740?

I also have a problem with Lenovo Thinkpad X1 carbon gen 11: it loads, but there is no usable camera, even with kernel 6.4.4 (also for some reason CONFIG_INTEL_SKL_INT3472 is disabled in Debian, so I have to rebuild kernel).

Have you also enabled CONFIG_VIDEO_V4L2_SUBDEV_API=y?

The wishlist bug for including CONFIG_INTEL_SKL_INT3472=m already exists:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1038385

@fhloston, thank you for the idea! It finally somewhat works! I can see picture via gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! xvimagesink

But /usr/bin/v4l2-relayd -i "icamerasrc buffer-count=7" -o "appsrc name=appsrc caps=video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! videoconvert ! v4l2sink name=v4l2sink device=/dev/video0" crashes with segmentation fault:

v4l2-relayd enchantment looks a bit different here:

/usr/bin/v4l2-relayd -i icamerasrc buffer-count=7 -o appsrc name=appsrc caps=video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw,format=YUY2 ! v4l2sink name=v4l2sink device=/dev/video0

Without putting args for -i and -o into quotes it starts ok, but relay no video. With the quotes it crashes. Unit file runs it with quotes.

I tried both options with ! video/x-raw,format=YUY2 part and without, it makes no difference (at least for now).

I also used 6.4.4 for a while but have reverted back to 6.3.7...

After playing I managed to fix sigfault, but I have no idea how... My best guess is that enabling debug in module v4l2loopback fix it...

So gst-launch-1.0 -v icamerasrc ! video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw,format=YUY2 ! v4l2sink device=/dev/video0 works wonderfully in chrome or mpv, but the camera is always on. I guess I can use it for now, manually switch it on and off when needed...

Unfortunately v4l2-relayd -d -i icamerasrc -o "appsrc name=appsrc caps=video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw,format=YUY2 ! v4l2sink name=v4l2sink device=/dev/video0" never enables camera and only gives black box as result.

Debugging shows nothing useful:(

P.S. I was surprised how bad video quality of this camera, I'd expect something amazing...
