In case of firmware assert snapshot of firmware memory is essential for debugging. Add firmware coredump collection support for PCI bus. Collect RDDM and firmware paging dumps from MHI and pack them in TLV format and also pack various memory shared during QMI phase in separate TLVs. Add necessary header and share the dumps to user space using dev coredump framework. Coredump collection is controlled by CONFIG_DEV_COREDUMP. Dump collected for a radio is 55 MB approximately.

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.
