** Description changed:
[SRU Justification]
[Impact]
Upstream commit d69d804845985 ("driver core: have match() callback in
struct bus_type take a const *") added const attribute the the second
parameter of the match callback, and this fails the build against
linux-6.11.
[Fix]
Ubuntu sauced change to accommodate to the API change. Also proposed to
the upstream as https://github.com/intel/ipu6-drivers/pull/261.
[Test Case]
- Install the built dkms binary package and linux-headers-
- oem-24.04b/noble. The dkms build should be triggered and complete
- successfully.
+ 1. install kernel headers packages. This should include kernel headers for
generic-6.8, oem-6.8, linux-hwe-6.8/jammy according to kernel-versions dkms
map. linux-oem-6.5 is outdated therefore is skipped here.
+ 2. install intel-usbio-dkms from -proposed and trigger dkms builds on all
mentioned kernel versions
+ 3. reboot into the kernels to check if intel-ipu6 module was loaded
automatically as before.
[Where problems could occur]
For Oracular, there is a new upstream release mostly for a next Intel
platform, but there are also code refinements as well. No specious side
effect found.
For Noble, there is only preprocessor macros to satisfy the API
compatibility.
[Other Info]
ipu6-drivers/oracular is used in linux/oracular and linux-
oem-6.11/noble, and ipu6-drivers/noble is used in linux/noble, linux-
oem-6.8/noble and linux-hwe-6.8/jammy. The Noble SRU is only to satisfy
compiling ipu6-drivers/noble against linux-oem-6.11/noble, but that's
not how linux-modules-ipu6-oem-24.04b is built.
