For easier debugging this patch adds dev coredump support to the driver. A dev coredump is generated in case the chip fails to start or an error in the interrupt handler is detected. The dev coredump consists of all chip registers and chip memory, as well as the driver's internal state of the TEF-, RX- and TX-FIFOs, it can be analyzed with the mcp251xfd-dump tool of the can-utils: https://github.com/linux-can/can-utils/tree/master/mcp251xfd Link: https://lore.kernel.org/r/20210304160328.2752293-2-mkl@pengutronix.de Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> |

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.
