We are using zephyr V3.6.0 and SDK version 0.16.5-1.
We are written code for Uart HW DMA for STM32H743 controller.
Assuming a buffer of 256 Bytes, A message sent with 257 bytes will cause an overflo…

**Describe the bug**
The async_user_callback can be triggered from two places one from the DMA transfer complete interrupt generated by the DMA and from an k_work queue timeout.
This timeout is not …

### Problem Description
# TLDR
`amdgpu` does not call the free callback that our Linux kernel driver passes into `rdma_get_pages()`. Results in stale ROCm-buffer:DMA-mapped-page cache entries and …

目前我已成功实现RKMPP解码+RGA硬件缩放的程序,但拿到MPP的解码数据后使用导入虚拟内存的方式传递给RGA去做缩放,速度上解码+缩放一帧4656*3496的时间大概是100ms上下浮动,然后发现将这一帧使用mpp从mjpeg数据格式转换为YUV才15ms上下, 然后拿给RGA做颜色格式的转换从YUV到RGB888竟然要80ms上下,基本耗时都在 这一步

If two Piksis are connected and both being bootloaded simultaneously then a DMA buffer overrun can occur.

host_get_copy_bytes_normal() in host-zephyr.c aligns down copy bytes to DMA specific value:
```
return ALIGN_DOWN(dma_copy_bytes, hd->dma_copy_align);
```
For some frame sizes, this can lead to a …
