Linux kernel source tree

There is no recovery mechanism in place yet to recover from mmu faults for DPU. We can only prevent the faults by making sure there is no misconfiguration. Rate-limit the snapshot capture for mmu faults to once per msm_atomic_commit_tail() as that should be sufficient to capture the snapshot for debugging otherwise there will be a lot of DPU snapshots getting captured for the same fault which is redundant and also might affect capturing even one snapshot accurately.

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 reStructuredText 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.
