Subject: Boots and seems to work with PREEMPT enabled
Date: Wed, 20 Sep 2023 12:14:23 +0100	[thread overview]
Message-ID: <6eb21cc7-05d5-c9be-6abd-07bdda64dcb6@kot-begemot.co.uk> (raw)

Added support for kernel side fpu store/restore and real kernel_fpu_begin/kernel_fpu_end using gcc intrinsics. Enabled PREEMPT.

It boots and seems to be alive and kicking. I do not notice any significant effect on performance either.

How do I test it from here onwards?

I am happy to throw the patches on the list as an RFC, though I would prefer to test first :)
