To work with scatter gather properly, fixes have been done in number of functions. I will explain requirement of each fixes one by one. start_slot: used to retrieve all request of SG during cleanup dwc3_gadget_giveback: We need to skip link TRB if it was one of the intermediate TRB of SG. dwc3_prepare_one_trb: We need to track all submitted TRBs during cleanup. Since, all TRBs would be serially allocated, so we can just keep starting slot info and we can always find rest of them. We need to pass sg node number, so that we cab appropriately program ISOC_FIRST/ISOC, Chain etc. dwc3_prepare_trbs: last_one should be set when it is last node of SG as well as last node of request_list. __dwc3_cleanup_done_trbs: It has been prepared after re-factorization of dwc3_cleanup_done_reqs. It is called for each TRB of SG. Signed-off-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com> |
