DWMAC Core 5.20 onwards supports HW descriptor prefetching. Additionally, it also depends on platform specific RTL configuration. This capability could be enabled by setting DMA_Mode bit-19 (DCHE). So, to enable this cability, platform must set plat->dma_cfg->dche = true and the DWMAC core version must be 5.20 onwards. Else, this capability wouldn`t be configured Signed-off-by: Mohammad Athari Bin Ismail <mohammad.athari.ismail@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
