media: ipu6: Invalidate MMU TLB in dma buffers creation#438
Merged
Conversation
This patch ensures that the MMU TLB is properly invalidated during the creation and mapping of DMA buffers for IPU devices. Without explicit invalidation, stale or incorrect entries in the TLB can cause invalid memory access in hardware. Signed-off-by: Hao Yao <hao.yao@intel.com>
