V7:
Ported this patch series forward to the current state of for-next.
MW now being allocated in core.
Split up rxe_pool changes into patches as requested by Jason.
Added some better comments.
Added error returns via ERR_PTR for APIs that return pointers.
Added some additional validation for rkeys in rxe_resp based on
chapter 9 of IBA.
Minor cleanup to rxe_mr which had duplicate entries.
V6:
Fixed two issues raised by Jason and Zhu.
Undid the replacement of rwlocks by spinlocks in patch 10/12. On further
reading it turns out rwlocks were the better choice.
Missing prototype for rxe_invalidate_mr. This was caused by a regression in
patch 05/12 which had dropped the actual use of the routine as well as the
prototype. Fixed.
V5:
This patch series is a collection of API extensions for the rdma_rxe driver.
With this patch set installed there are no errors in pyverbs run-tests and
31 tests are skipped down from 56. The remaining skipped test cases include
- XRC tests
- ODP tests
- Parent device tests
- Import tests
- Device memory
- MLX5 specific tests
- EFA tests
It continues from the previous (v4) set which implemented memory windows and
has had a number of individual patches picked up in for-next.
This set (v5) includes:
Ported to current head of tree
Memory windows patches not yet picked up
kernel support for the extended user space APIs:
- ibv_query_device_ex
- ibv_create_cq_ex
- ibv_create_qp_ex
Fixes for multicast which is not currently working
This patch set depends on a matching rdma-core user space library patch set.
In order to run correctly it is necessary to configure by hand the EUI64 link
local IPV6 address on systems which use a random link local address (like
Ubuntu).
