This patch implements IB_WR_REG_SIG_MR posted by the user.
Baisically this WR involvs 3 WQEs in order to prepare and properly
register the signature layout:
1. post UMR WR to register the sig_mr in one of two possible ways:
* In case the user registered a single MR for data so the UMR data
segment
consists of:
- single klm (data MR) passed by the user
- BSF with signature attributes requested by the user.
* In case the user registered 2 MRs, one for data and one for
protection,
the UMR consists of:
- strided block format which includes data and protection MRs and
their repetitive block format.
- BSF with signature attributes requested by the user.
2. post SET_PSV in order to set the for the memory domain initial
signature parameters passed by the user.
3. post SET_PSV in order to set the for the wire domain initial
signature parameters passed by the user.
This patch also introduces some helper functions to set the BSF correctly
and determining the signature format selectors.
Has it already been explained somewhere what the abbreviations KLM, BSF and
PSV stand for ?
Bart, these are all HW T10 related objects/concepts, we made an effort
to keep them contained within the mlx5 driver such that they don't
show up on the IB core layer. If this helps for the review, Sagi can
spare few words on each, sure.
Hello Or,
I would certainly appreciate it if these abbreviations could be
clarified further. That would allow me to understand what has been
explained in the above patch description :-)
Bart.
