Michael Chan says: ==================== bnxt_en: Prepare to support new P7 chips This patchset is to prepare the driver to support the new P7 chips by refactoring and modifying the code. The P7 chip is built on the P5 chip and many code paths can be modified to support both chips. The whole patchset to have basic support for P7 chips is about 20 patches so a follow-on patchset will complete the support and add the new PCI IDs. The first 8 patches are changes to the backing store logic to support both chips with mostly common code paths and datastructures. Both chips require host backing store memory but the relevant firmware APIs have been modified to make it easier to support new backing store memory types. The next 4 patches are changes to TX and RX ring indexing logic and NAPI logic. The main changes are to increment the TX and RX producers unbounded and to do any masking only when needed. These changes are needed to support the P7 chips which require additional higher bits in these producer indices. The NAPI logic is also slightly modifed. The last patch is a rename of BNXT_FLAG_CHIP_P5 to BNXT_FLAG_P5_PLUS and other related macro changes to make it clear that the P5_PLUS macro applies to P5 and newer chips. ==================== Link: https://lore.kernel.org/r/20231120234405.194542-1-michael.chan@broadcom.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.
