[Regression] Is this issue a regression: (Y/N) Y The first bad commit: commit 588dcac2361011556934166d93da62dae712ce69 Author: Pavan Nikhilesh Date: Fri Jun 7 16:06:25 2024 +0530 eventdev/dma: reorganize event DMA ops Re-organize event DMA ops structure to allow holding source and destination pointers without the need for additional memory, the mempool allocating memory for rte_event_dma_adapter_ops can size the structure to accommodate all the needed source and destination pointers. Add multiple words for holding user metadata, adapter implementation specific metadata and event metadata.

Please confirm it need fix or not on ABI compatibility testing or it needn't test for ABI compatibility testing. Thanks. -- You are receiving this mail because: You are the assignee for the bug.
