We should also do it right for TAPQ with t bit set. I remember
Christian already warned about this but we did not implement it.


Yes, I have some blurry memories of something similar myself. I wonder
if there was a reason, or did we just forget to address this issue.


I will integrate it in the next iteration too, even it is not IRQ, the PQAP hook patch can be more general.

After all, I will not do this, I remember the reason why we did not do it once: simply it is not intercepted until we enable it.

So we will handle it when we enable the TAPQ-t interception

Pierre
