+2022.1.1 Patch Updates
+----------------------
 - Ported changes from pull request https://github.com/Xilinx/dma_ip_drivers/pull/167 to fix XRT build issues while integrating qdma linux driver in to XRT stack
 
+2022.1.2 Patch Updates
+----------------------
+- Added VF 4K queues support for CPM5 design. This feature is applicable only when corresponding RTL support is added.
 
 KNOWN ISSUES:
 =============
 - CPM5 Only
-	- Sufficient host memory is required to accommodate 4K queues. Tested only upto 2099 queues with our test environment though driver supports 4K queues.
+	- Sufficient host memory is required to accommodate 4K queues. Tested only upto 2099 queues for PFs with our test environment though driver supports 4K queues.
+	- VF 4K queue support is not fully verified due to pdi issues
 
 - All Designs
 	- In interrupt mode, Sometimes completions are not received when C2H PIDX updates are held for 64 descriptors
