Ido Schimmel says: ==================== mlxsw: spectrum: Prepare for XM implementation - prefix insertion and removal Jiri says: This is a preparation patchset for follow-up support of boards with extended mezzanine (XM), which is going to allow extended (scale-wise) router offload. XM requires a separate PRM register named XMDR to be used instead of RALUE to insert/update/remove FIB entries. Therefore, this patchset extends the previously introduces low-level ops to be able to have XM-specific FIB entry config implementation. Currently the existing original RALUE implementation is moved to "basic" low-level ops. Unlike legacy router, insertion/update/removal of FIB entries into XM could be done in bulks up to 4 items in a single PRM register write. That is why this patchset implements "an op context", that allows the future XM ops implementation to squash multiple FIB events to single register write. For that, the way in which the FIB events are processed by the work queue has to be changed. The conversion from 1:1 FIB event - work callback call to event queue is implemented in patch #3. Patch #4 introduces "an op context" that will allow in future to squash multiple FIB events into one XMDR register write. Patch #12 converts it from stack to be allocated per instance. Existing RALUE manipulations are pushed to ops in patch #10. Patch #13 is introducing a possibility for low-level implementation to have per FIB entry private memory. The rest of the patches are either cosmetics or smaller preparations. ==================== Link: https://lore.kernel.org/r/20201110094900.1920158-1-idosch@idosch.org 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.
