David Awogbemil says: ==================== GVE Raw Addressing Patchset description: This patchset introduces "raw addressing" mode to the GVE driver. Previously (in "queue_page_list" or "qpl" mode), the driver would pre-allocate and dma_map buffers to be used on egress and ingress. On egress, it would copy data from the skb provided to the pre-allocated buffers - this was expensive. In raw addressing mode, the driver can avoid this copy and simply dma_map the skb's data so that the NIC can use it. On ingress, the driver passes buffers up to the networking stack and then frees and reallocates buffers when necessary instead of using skb_copy_to_linear_data. Patch 3 separates the page refcount tracking mechanism into a function gve_rx_can_recycle_buffer which uses get_page - this will be changed in a future patch to eliminate the use of get_page in tracking page refcounts. Changes from v9: Patch 4: Use u64, not u32 for new tx stat counters. ==================== Reviewed-by: Alexander Duyck <alexanderduyck@fb.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.
