Subject: RFC: extern illegal instruction trap and trap RDCYCLE
Date: Tue, 17 Sep 2024 14:08:50 +0100 [thread overview]
Message-ID: <20240917130853.18657-1-ben.dooks@codethink.co.uk> (raw)
This is a RFC series to change how the illegal instruction trap
is handled and then how to trap RDCYCLE and emulate it with RDTIME
instead.
I did this when we found multiple libraries using RDCYCLE and
upgrading multiple runners to newer kernels caused many problems
