[ECOS] FW: Questions about dsr?

[Retallack, Mark (Poole)]

DSR's cannot block. (We learnt the hard way after a very strange crash and
not reading the documentation). A DSR is just a delayed ISR, so you don't
want to be doing to much in a DSR that cannot be done in a thread.

Hi to all, 

I have some questions about DSR as following… 

1.Can DSR waits on semphore? 
2.If one DSR is blocked, can kernel switch to another DSR? 

Thank you for answering these question.
