I know the problem now, please close this issue directly. Thank you! Just replace it with memory reading. I'll use VMMLL_readEX instead

I'm trying to transmit some data, but DMA buffers seems to overflow under used data rates. I think this is kinda similar to https://github.com/xtrx-sdr/xtrx_linux_pcie_drv/issues/7, I tried to increas…

Shim DMA, Mem DMA and Tile DMA descriptors have fields with different lengths.
e.g. the buffer_length field is 32-bits in AIE2 for shim tiles, 17-bits for mem tiles and 14-bits for compute tiles.

# The setup
Using the `EVK MIMXRT685` as `I2S` SLAVE configured as:
- TDM / DSP mode A (mono)
- 48kHz (SCK at ~25MHz)
- 16 slots (channels) per frame
- 512 SCK per frame
- 32 SCK per slot
- 3…

It was noted by James Munns that we may need to use an `UnsafeCell` internal wrapper on the DMA reception buffers to prevent invoking undefined behavior by the Rust compiler (i.e. two owners of the me…

The uart-dma example does not show how to send data with different length using dma.
Is this not supported by this crate or is it even a hardware limitation?
example:
```rust

**Describe the bug**
I build and run `samples/drivers/led_strip/` on the MIMXRT1050_EVK with DMA enabled for LPSPI. However, no data is put on MOSI pin. When I disable DCACHE, the data is put on the …

Hi, I'm testing RDMA via RoCEv2 connectivity and we're using `dma-buf` instead of `nv-peer-mem` and it's failing but I'm unsure of the fix/why.
I setup the test on Ubuntu Kubernetes Pods (based on …

in case no dma device is available, mpp thinks that dma allocator is still valid. I think it should check the availablity of at least one device device in dma devices.
here is a potential fix.
