We currently use the Ubuntu kernel sources, available from:
- http://kernel.ubuntu.com/git/ubuntu/ubuntu-focal.git/
+ http://kernel.ubuntu.com/git/ubuntu/ubuntu-jammy.git/
Ubuntu will maintain those kernels till:
https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable
+ or
+ https://pve.proxmox.com/pve-docs/chapter-pve-faq.html#faq-support-table
+
+ whatever happens to be earlier.
Additional/Updated Modules:
directory remains clean even with extra patches applied since it does not
contain a .git directory, but a reference to the (still pristine) submodule:
-$ cat build/ubuntu-focal/.git
+$ cat build/ubuntu-jammy/.git
If you mistakenly cloned the upstream repo as "normal" clone (not via the
submodule mechanics) this means that you have a real .git directory with its
---------------
depends on latest kernel and header package within a certain kernel series,
-e.g., pve-kernel-4.15 / pve-headers-4.15
+e.g., pve-kernel-5.15 / pve-headers-5.15
git clone git://git.proxmox.com/git/pve-kernel-meta.git
We ship this list in /lib/modprobe.d/blacklist_pve-kernel-<VERSION>.conf
The user typically edit /etc/modules to enable a specific watchdog device.
+Debug kernel and modules
+------------------------
+
+In order to build a -dbgsym package containing an unstripped copy of the kernel
+image and modules, enable the 'pkg.pve-kernel.debug' build profile (e.g. by
+exporting DEB_BUILD_PROFILES='pkg.pve-kernel.debug'). The resulting package can
+be used together with 'crash'/'kdump-tools' to debug kernel crashes.
+
+Note: the -dbgsym package is only valid for the pve-kernel packages produced by
+the same build. A kernel/module from a different build will likely not match,
+even if both builds are of the same kernel and package version.
