Which is why the kernel folks' insistence on keeping drivers in the kernel rather than sandboxed user processes is so backwards...https://twitter.com/CopperheadOS/status/863454511674871808 …
Most people's loads are NOT hw-access-bound but cpu-, memory-, and/or gpu-bound.

Oh certainly. I want the mechanism to work for network card drivers too.
-
If your loads are network-card-bound, then you need some more attention to isolating the driver in a way that doesn't hurt your perf.
-
But that only affects datacenter type users, not mobile, laptop, desktop, small server users.

So everyone else is suffering miserable security model for the sake of enterprise/datacenter network performance needs...
-
Oh certainly. We're over optimized for the wrong users in many cases.
