It's observed that no more completion occurs after a few incorrect posts.
Actually, it will block the polling. we can easily reproduce it by the below
pattern.
a. post correct RDMA_WRITE
b. poll completion event
while true {
c. post incorrect RDMA_WRITE(wrong rkey for example)
d. poll completion event <<<< block after 2 incorrect RDMA_WRITE posts
}
V4 add new patch from Bob where it make requester stop executing qp
operation as soon as possible.
Both blktests and pyverbs tests are passed fine.
Bob Pearson (1):
RDMA/rxe: Split qp state for requester and completer
Li Zhijian (3):
RDMA/rxe: Update wqe_index for each wqe error completion
RDMA/rxe: Generate error completion for error requester QP state
RDMA/rxe: Fix typo in comment
