Thomas Falcon says: ==================== ibmvnic: Performance improvements and other updates The first three patches utilize a hypervisor call allowing multiple TX and RX buffer replenishment descriptors to be sent in one operation, which significantly reduces hypervisor call overhead. The xmit_more and Byte Queue Limit API's are leveraged to provide this support for TX descriptors. The subsequent two patches remove superfluous code and members in TX completion handling function and TX buffer structure, respectively, and remove unused routines. Finally, four patches which ensure that device queue memory is cache-line aligned, resolving slowdowns observed in PCI traces, as well as optimize the driver's NAPI polling function and to RX buffer replenishment are provided by Dwip Banerjee. This series provides significant performance improvements, allowing the driver to fully utilize 100Gb NIC's. ==================== Link: https://lore.kernel.org/r/1605748345-32062-1-git-send-email-tlfalcon@linux.ibm.com Signed-off-by: Jakub Kicinski <kuba@kernel.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.
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.
