Bug description:
[SRU Justification]
[Impact]
Miss AMD MIPI camera 4.0 support.
[Fix]
* https://lore.kernel.org/linux-
media/20250828100811.95722-1-Bin.Du at amd.com/
[Test Case]
1. install kernel from -proposed channel with camera module installed,
2. Check device driver loaded:
```
$ media-ctl -p
Media controller API version 6.17.0
Media device information
------------------------
driver amd_isp_capture
model amd_isp41_mdev
...
$ gst-device-monitor-1.0 Video/Source
Probing devices...
Device found:
name : amd_isp_capture (V4L2)
class : Video/Source
...
```
3. Check camera functioning well:
```
$ gst-launch-1.0 v4l2src ! videoconvert ! autovideosink
```
[Where problems could occur]
New hardware support. Expect further updates.
[Other Info]
Unlike the previous driver implementations, the camera sensor is
delegated to sensor firmware fixed in bug 2119501. There is no more
ov05c10 part as done for linux-oem-6.11 and linux-oem-6.14, but
ov05c10 is still used and provided by ipu6-drivers.
Same with linux-oem-6.11 and linux-oem-6.14, there is no hard
dependency to libcamera to use AMD MIPI.
Nominiate for Questing as hwe-6.17 will be in the migration path for
linux-oem-6.14. And oem-6.17 of course.
========== SRU justification for linux-oem-6.11/6.14 ==========
[SRU Justification]
[Impact]
Miss AMD MIPI camera 4.0 support.
[Fix]
* kernel: https://github.com/amd/Linux_ISP_Kernel/tree/4.0 based on v6.14-rc2.
* Gstreamer or libcamera: https://github.com/amd/Linux_ISP_libcamera/tree/3.0 based on upstream v0.4.0.
- this depends on bug 2092060
[Test Case]
1. install kernel from -proposed channel with camera module installed,
2. upgrade libcamera, pipewire, install libcamera-tools from prebuilt
PPA https://launchpad.net/~vicamo/+archive/ubuntu/ppa-testfield
3. Test camera availability:
```
$ sudo cam -l
[0:00:16.776607397] [3034] INFO Camera camera_manager.cpp:327 libcamera v0.4.0
[0:00:16.778052318] [3039] WARN AmdIsp4 isp4.cpp:706 Env var LIBCAMERA_AMD_CONFIG_FILE not found
[0:00:16.778059201] [3039] WARN AmdIsp4 isp4.cpp:708 Using default config file 'config-default.yaml'
[0:00:16.778347069] [3039] INFO AmdIsp4 isp4.cpp:396 sensor id: 'ov05c_mipi0'
[0:00:16.778487742] [3039] WARN AmdIsp4 isp4.cpp:706 Env var LIBCAMERA_AMD_CONFIG_FILE not found
[0:00:16.778492591] [3039] WARN AmdIsp4 isp4.cpp:708 Using default config file 'config-default.yaml'
Available cameras:
1: (ov05c_mipi0)
```
4. Start camera streaming to check if it actually works:
```
$ gst-launch-1.0 libcamerasrc ! \
video/x-raw,format=YUY2,width=1280,height=720,framerate=30/1 ! \
videoconvert ! \
autovideosink
```
[Where problems could occur]
This kernel driver revision is isolated from other components, and
therefore should not project additional risk to amdgpu itself. It's
still under development but sufficient for early platform enablement,
and it is being upstreamed and is expecting to complete at v6.16.
[Other Info]
Nominate only for oem platform enablement. For Plucky or later, the
current plan is to take the upstreamed revision instead if AMD can
catch the mainline inclusion train. Otherwise, we may still have to
fallback to this beta revision.
