In enhanced DMA the vrings are handled internally by the FW and are not exposed to the driver. Instead, the driver handles descriptor rings, which are mapped by the FW to vrings. The completions of the TX and RX descriptors are notified to the driver using status rings. Each status ring descriptor includes information of the completed descriptors and the ring id of their descriptor ring. This patch changes struct vring to generic wil_ring to allow its reuse for enhanced DMA descriptor rings and adds the descriptor and status rings specific descriptors. The vring debugfs entries have changed as follows: - dbg_vring_index has changed to dbg_ring_index - vrings has changed to rings - vring_idle_trsh has changed to ring_idle_trsh - vring_index has changed to ring_index Signed-off-by: Gidon Studinski <gidons@codeaurora.org> Signed-off-by: Maya Erez <merez@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> |

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
