Waaa. So you want me to respect sg_table size in uasp. It is not done
yet.
Could we change sg_tablesize to sg_supported? So I don't have to support
it? From DWC3 point of view you just need to stop in the middle of
request and continue later. I don't think anyone has a restriction here
(I don't really know where this limit is comming from). If you don't
then I need to split the sg list into two or more requests which will
probably end up with the same thing. And, as recently learned a sg_list
of 4 entries could be mapped into one. If I have to split it manually we
may lose that.
If you really want an upper limit (which you copied from usb core where
it is treated as 0/1) then you could rename it so sg_entries or
something like that.
this is taken care of when we're kicking_transfers. See that we stop
when we run out of TRBs.
Yes, we stop. But I don't see that we resume at the point where we
stopped.
