AxiDMA driver exposed the dma_set_max_seg_size() to the DMAENGINE. It shall helps the DMA clients to create size-optimized linked-list for the controller. However, there are certain situations where DMA client might not be abled to benefit from the dma_get_max_seg_size() if the segment size can't meet the nature of the DMA client's operation. In the case of ALSA operation, ALSA application and driver expecting to run in a period of larger than 10ms regardless of the bit depth. With this large period, there is a strong request to split the linked-list in the AxiDMA driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
