Debug Kernel

rarebit

Hi, I have a (regular) UP board and see there are the following kernel choices. Is there any links that explain the differences in these kernels? Thanks in advance

linux-image-extra-virtual-hwe-18.04-upboard - Extra drivers for Virtual Linux kernel image
linux-image-generic-hwe-18.04-upboard - UP board Linux kernel image
linux-image-lowlatency-hwe-18.04-upboard - lowlatency Linux kernel image
linux-image-virtual-hwe-18.04-upboard - Virtual Linux kernel image
linux-signed-image-generic-hwe-18.04-upboard - Signed Generic Linux kernel image
linux-signed-image-lowlatency-hwe-18.04-upboard - Signed Lowlatency Linux kernel image

Virtual kernels are intended to be utilized inside a virtual machine
The lowlatency are needed for systems/applications that operate in low-latency situation (like audio recording and sensors readings) but not really realtime
The signed kernels are needed for system that forces security checks at boot, but it is not the case on UP boards with standard BIOS, so you can use the normal (unsigned) kernels
