We are using uClinux (2.4.32-uc0) on a Microblaze processor
here and am hunting down a problem. In doing so, I am looking at entry.S
and have a question how KSP is used. It is first set in head.S and is
read in SAVE_STATE and written in RETURN. On the surface one would assume
that KSP would maintain a value close to its original value (+- SAVE_SIZE) but
I see it changing greatly. Could somebody enlighten me on what I am
missing on the usage of KSP in 2.4? Thanks Gary |
