** Description changed:
- v6.13-rc2 cdd30ebb1b9f3 ("module: Convert symbol namespace to string
+ [ Impact ]
+
+ Upstream kernel API changes in v6.13. The details can be found in the
+ below.
+
+ [ Test Plan ]
+
+ 1. Install kernel v6.13 headers. Currently it is only available through
+ prebuilt headers packages in https://kernel.ubuntu.com/mainline/.
+
+ 2. Install intel-ipu6-dkms, intel-ipu7-dkms from plucky-proposed.
+
+ 3. The dkms should be compiled automatically with the running kernel. To
+ compile it against the just installed v6.13 kernels:
+
+ ```
+ $ for k in $(dpkg -l| awk '$2 ~ /^linux-headers-.*-generic$/ { print
substr($2, length("linux-headers-") + 1); }'|sort -V -r); do
+ sudo dkms install --force ipu6-drivers/0~git202411190607.0ad49882 -k $k;
+ sudo dkms install --force ipu7-drivers/0~git202412060257.0fc08453 -k $k;
+ done
+ ```
+
+ [ Where problems could occur ]
+
+ The proprocessor macros were done to provide API compatibility with
+ previously released kernels. The entity source to be compiled does not
+ change.
+
+ [ Other Info ]
+
+ Only nominate for Plucky because that's only available in Plucky (now
+ 6.14).
+
+ ========== original bug report ==========

+ * v6.13-rc2 cdd30ebb1b9f3 ("module: Convert symbol namespace to string
literal") expects string literals than symbol names as usual, therefore
