|
Kernel available :
|
|
This section lists available Debian kernel variants. Each type addresses specific requirements such as
|
|
hardware support, virtualization, real-time processing, or Secure-Boot compatibility.
|
|
|
|
*+bpo* : Debian Backported Kernel
|
|
Backported kernels from Debian testing or unstable, offering newer features, improved hardware
|
|
support, and updated drivers, especially useful on modern systems or special-purpose hardware.
|
|
|
|
*cloud* : Special lightweight images for KVM
|
|
Cloud-optimized kernels tailored for virtualized environments (e.g., KVM, OpenStack). These images
|
|
are minimal, fast-booting, and reduce unnecessary modules and firmware to save memory and time.
|
|
|
|
*unsigned* : Unsigned Kernel
|
|
Kernel images without Microsoft Secure Boot signatures. These require custom Secure Boot key
|
|
management (e.g., using your own PK/KEK/DB or MOK with shim) and will not boot on locked-down systems.
|
|
|
|
*preempt_rt* : Special Kernel for real-time-computing
|
|
Real-time variant with full preemption enabled. Designed for workloads needing deterministic latency
|
|
such as robotics, industrial control, scientific instrumentation, or low-latency audio processing.
|
|
|
|
Note :
|
|
All kernel packages NOT marked as *unsigned* are **Microsoft-signed** and should work out of the
|
|
box with Secure-Boot enabled, assuming the UEFI firmware trusts Microsofts root keys.
