Yeah I had that already setup and I could not figu

I'm bringing up support for a new RISC-V core but I'm running into some
issues around the sys tick.
My tick timer interrupt is disabled at activating a task, clearly this is
not correct. This is code used across all architectures so I

My tick timer interrupt is disabled at activating a task, clearly this is
not correct. This is code used across all architectures so I'm sure I just
do not understand something
