Subject: [RFC v2 23/25] RDMA/irdma: Extend CQE Error and Flush Handling for GEN3 Devices
From: Shiraz Saleem <shiraz.saleem@...el.com>
Enhance the CQE error and flush handling specific to GEN3 devices.
Unlike GEN1/2 devices, which depend on software to generate completions
in error, GEN3 devices leverage firmware to generate CQEs in error for
all WQEs posted after a QP moves to an error state.
Key changes include:
- Updating the CQ poll logic to properly advance the CQ head in the
event of a flush CQE.
- Updating the flush logic for GEN3 to pass error WQE idx
for SQ on an AE to flush out unprocessed WQEs in error.
- Isolating the decoding of AE to flush codes into a separate routine
irdma_ae_to_qp_err_code. This routine can now be leveraged to
flush error CQEs on an AE and when error CQE is received for SRQ
