I am not a big fan of IBM but I have to say that because they defined the PC bios and interrupt structure, we all owe them a debt of gratitude for the continued degree of compatibility on the X86 machines.
I thought that there was already a stable rt-preempt kernel for 4.9 LTS and 4.14 LTS and they were approaching stable on the 4.19 LTS rt-preempt kernel. However, I now realize that I was looking at the GitHub for rt-preempt generic. It looks like there maybe something approaching stable for 4.9 LTS for Pine64. I am not sure of the relationship between the Pine64 and RockPro64. Pine64+ uses an Allwinner cpu, while the RockPro64 uses RK3399 which is Armv8. I have built kernels in the past but am not an expert. Alan > Message: 4 > Date: Fri, 8 Mar 2019 08:56:46 -0800 (PST) > From: "Peter C.
