SP6 camera detected, sensor ov7251 9-0060 has not format compatible with the IPU3
After following all the instructions for enabling the camera in the camera support page and getting the firmware file based on this blog post (rebooting afterwards also): https://neilzone.co.uk/2021/08/working-front-and-rear-cameras-on-debian-11-on-a-surface-pro-6-surfacebook-2-and-surface-go/ The camera on the SP6 gets detected:

Too long for Github, see here: https://r2.mprogramavimai.lt/dmesg.txt
Reply if any additional information is needed, and than you for the excruciating work of bringing Linux to these great devices!
Same issue here with SG2 using the 6.10.5-surface-1 kernel.
Running qcam brings up a similar list of errors for me:

The folks have done such a fantastic job getting things working: this is the only wrinkle for me!
qcam is using libcamera 0.2
I'm on a SP5 running ubuntu 24 and I fixed this by jumping into the /usr/lib/x86_64-linux-gnu folder and redirecting all of the libcamera 0.2 files to point at libcamera 0.3.1.
I used symlinks like sudo ln -s libcamera.so.0.3.1 libcamera.so.0.2.0
@surface-enjoyer Sorry, your solution doesn't work for me. The default symlinks are already redirected to version 3, but after redirecting the 0.2.0 to 0.3.1, it just fails:
qcam: symbol lookup error: qcam: undefined symbol: _ZN9libcamera13CameraManager8version_B5cxx11E
On sp4 I get similar

Which looks fairly OK (?) But qcam gives errors and no cameras can be selected in the dropdown.

I did some more investigation on this. It would appear that qcam is using version 0.2.0 pf libcamera as @surface-enjoyer points out, and cam is using the correct 0.3.2 version as installed by the instructions linked by the OP.
Indeed the installation instructions linked
Update the symlinks as required:
Installing symlink pointing to libcamera-base.so.0.3.2 to /usr/lib/x86_64-linux-gnu/libcamera-base.so.0.3
Installing symlink pointing to libcamera-base.so.0.3 to /usr/lib/x86_64-linux-gnu/libcamera-base.so
Installing symlink pointing to libcamera.so.0.3.2 to /usr/lib/x86_64-linux-gnu/libcamera.so.0.3
Installing symlink pointing to libcamera.so.0.3 to /usr/lib/x86_64-linux-gnu/libcamera.so
So I tried to rebuild the optional qcam from https://libcamera.org/getting-started.html
This took me a while as I've not touched c++ build systems for 25 years.
But eventually I figured that
meson setup --reconfigure -Dqcam=disabled build
seemed to set the right build options.
cam application : YES
qcam application : YES
lc-compliance application: YES
And installed all the dependent package for qcam.
Unfortunately the qcam does not build
/usr/bin/ld: src/apps/qcam/qcam.p/cam_select_dialog.cpp.o: in function `QString::toStdString() const':
/usr/include/x86_64-linux-gnu/qt6/QtCore/qstring.h:1477:(.text._ZNK7QString11toStdStringEv[_ZNK7QString11toStdStringEv]+0x35): undefined reference to `QByteArray::toStdString() const'
I do not have the inclination to try and fix this!
However - it occurred to me that just because qcam is not working, doesn't mean the camera isn't.
so I tried (as per instructions):
gst-launch-1.0 libcamerasrc camera-name='\\_SB_.PCI0.I2C2.CAMF' !
video/x-raw,width=1280,height=720,framerate=30/1,format=NV12
! videoconvert ! video/x-raw,format=YUY2 ! videoconvert !
v4l2sink device=/dev/video42
and got the error
pipeline could not be constructed: no element "libcamerasrc".
I tried to work this out for a while and then gave up!
It worked fine for me, when I used Ubuntu 24 on my SP6. I just followed the github guide and built v4l2loopback myself instead of installing from the repo. I think I built libcamera from lateset source as well.
Maybe try if Cheese recognizes both your cams
