It is important for the SCSI core to know the residual byte count. Hence, extract the residual byte count from the UFS response and pass it to the SCSI core. A few examples of the output of a debugging patch that has been applied on top of this patch: [ 1.937750] cmd 0x12: len = 255; resid = 241 [ ... ] [ 1.993400] cmd 0xa0: len = 4096; resid = 4048 [ ... ] Signed-off-by: Bart Van Assche <bvanassche@xxxxxxx> --- drivers/ufs/core/ufshcd.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/ufs/core/ufshcd.c b/drivers/ufs/core/ufshcd.c index ce7b765aa2af..7bbbae9c7c61 100644 --- a/drivers/ufs/core/ufshcd.c +++ b/drivers/ufs/core/ufshcd.c @@ -5238,6 +5238,9 @@ ufshcd_transfer_rsp_status(struct ufs_hba *hba, struct ufshcd_lrb *lrbp, int scsi_status; enum utp_ocs ocs; + scsi_set_resid(lrbp->cmd, + be32_to_cpu(lrbp->ucd_rsp_ptr->sr.residual_transfer_count)); + /* overall command status of utrd */ ocs = ufshcd_get_tr_ocs(lrbp, cqe);
