Re: [Qemu-arm] [PATCH] target-arm: Priority masking with basepri on v7m

Thanks for the swift reply.

Michael's changes look very good indeed. Thank you for pointing them out.

No need to consider this any further then.

Cheers,

François.

There are a lot of problems with our NVIC priority handling
right now. You might like to take a look at the patch set that
Michael Davidsaver sent out earlier this month:
https://lists.nongnu.org/archive/html/qemu-devel/2015-11/msg01542.html

That has some problems but I think it's probably the way we're
going to go to fix up the NVIC.

thanks
