grayresearch commented 5 months ago

Specify the new cte control bit in mcx_selector CSR: custom operation trap enable. This enables emulation of absent custom instructions, emulation of absent composable extensions, and virtualization of stateful composable extensions state contexts.

It addresses #19, #20, #24.
