Raspberry Pi Low-Latency PREEMPT Kernel 5.15.65-llat
This is a Low-Latency PREEMPT kernel build. Both 32 and 64 bit packages are included.
64-bit kernel can be installed on 32-bit system.
This is built from unpatched raspberrypi/linux sources, with config options PREEMPT, 1000 Hz timer, performance CPU governor.
You may find that this kernel gives better results for your application than PREEMPT_RT, with less tuning effort, even though it does not score as well on synthetic latency tests. This might be because PREEMPT_RT on RPi introduces spinlocks to avoid conflict with RPi OS use of FIQ.
deb packages are attached below. For installation or build instructions, see the repo wiki:
