So.....in order to ‘fix’ a hardware problem in the Intel processors it is necessary to write code for operating systems?

Harder to do a recall of 20+ years worth of processors than it is to write software to work around the bugs.

Even the recent generations (2010+) would be a hard sell.

So.....in order to ‘fix’ a hardware problem in the Intel processors it is necessary to write code for operating systems?

Yes, because of the way the OS enables/enabled the CPU to perform protected memory operations on its behalf. A vulnerability was discovered that enables "malicious code" as simple as Javascript to access the protected memory in the CPU.

The OS patch disables the OS kernel from allowing the CPU to perform protected memory functions that are vulnerable and move those functions to the OS by creating separate memory tables for the OS to access.

That results in the performance hit some are reporting.

I'm not sure the performance hit is 30% as some say,I've not seen any benchmarks proving that.
