RELEASE: 2020.1 Patch
=====================
RELEASE: 2020.2
===============
This release is based on DPDK v19.11 and contains QDMA poll mode driver and
QDMA test application. This release is validated on QDMA4.0 2020.1 Patch based
example design.
QDMA test application.
This release is validated for VCU1525 and U200 devices on QDMA4.0 2020.2 based example design
and QDMA3.1 2020.2 based example design.
This release includes a patch file for dpdk-pktgen v19.12.0 that extends
dpdk-pktgen application to handle packets with packet sizes more than 1518 bytes
and it disables the packet size classification logic in dpdk-pktgen to remove
application overhead in performance measurement.
This patch is used for performance testing with dpdk-pktgen application.
This patch is used for performance testing with dpdk-pktgen application.
The driver is validated against dpdk-pktgen and testpmd applications for API compliance.
SUPPORTED FEATURES:
......@@ -75,6 +77,14 @@ SUPPORTED FEATURES:
- Verified QDMA DPDK software with IOVA=VA mode by enabling hugepage allocation matching support in DPDK
(i.e. by specifying the --match-allocations command-line switch to the EAL).
2020.2 Updates
--------------
- Added support for detailed register dump
- Added support for post processing HW error messages
- Added support for Debug mode and Internal only mode
- Resolved the issue related to mbuf packet length
- Fixed VF FMAP programming of qmax issue by setting qmax to the actual user configured total queue number
KNOWN ISSUES:
=============
- Function Level Reset(FLR) of PF device when VFs are attached to this PF results in mailbox communication failure
