The kernel was unstable and the system hard locked frequently with the patches enabled (with and without the GFP_KERNEL patch). But I was able to map out all the controller functions to the bits in the first 16 quadlets. I will write up my findings and send them later.
I'm sorry but I have applied wrong changes to the remote branch for kernel patch. It includes three issues:
- call vfree() to memory object allocated by kmalloc()
- bring kernel oops due to double free corruption of 'tscm->status'
- invalid page mapping of 'tscm->status' to process' VMA
I pushed additional three patches. Would you please test with them?
MMAP works fine and stable with the three additional patches.
