[Cbe-oss-dev] [RFC/PATCH 2/2] spufs: Add a "capabilities" file to spu contexts

[Mike Kistler]

Uli,

I added support for single stepping a few months ago ... as soon as I 
learned you might be interested in using this feature.  I should be 
available in the SDK 2.1 version of the sim.  However, I don't think there 
is an easy check to determine if the support is there or not.  If this is 
important, I could probably figure out something (like a version number 
check or something).

Regards,
Mike

Mike, you mentioned that the simulator may not support the SPE single-step
feature.  Is that true for any version of the simulator?  Is there
something that would allow to test for whether the feature is supported?
