Builders Of The PREEMPT_RT Patch Set To Revive An Previous Intel Undertaking
You might not have identified that Intel has been engaged on creating an actual time Linux Kernel, however apparently they’ve been for greater than 10 years. They’ve introduced new life to the mission by buying Linutronix, an professional in actual time Linux functions, for an undisclosed sum of money. Amongst different tasks, Linutronix was the architect of PREEMPT_R, a patch set now maintained by a gaggle of programmers who work to make Linux kernel as preemptible as attainable on all kinds of processors.
Through the years the upkeep and improvement of PREEMPT_R has languished as individuals moved on to different tasks, however will now have the backing of Intel. In addition they get one other profit, within the type of Linutronix’s CTO Thomas Gleixner who has been a significant driver in creating safety mitigations for the Linux kernel’s x86 codebase.
Intel and the open supply group as soon as appeared to fully separated, however that’s clearly not true anymore. With even Microsoft providing Linux primarily based Azure cases, the open supply group has develop into increasingly built-in with the big firms they provided a substitute for. Let’s hope not less than a few of their altruism is retained as they’re absorbed into varied companies.
