Actually, on second thought maybe it's cleaner just to pass the SQ
information from user->kernel? There's not really anything that can
go wrong with RQs, and it's probably safer not to have the same info
passed in two different ways.
maybe something like
struct mlx4_ib_create_qp {
__u64 buf_addr;
__u64 db_addr;
__u8 log_sq_stride;
__u8 log_sq_bb_per_wqe;
__u8 reserved[6];
};
and then use the RQ and SQ sizes and number of gather entries from the
normal part of the command to figure the rest out?
Any opinion on which is preferable?
- R.
