To lower CPU overhead, future userspace will be switching to pinning iova and avoiding the use of relocs, and only include cmds table entries for IB1 level cmdstream (but not IB2 or state-groups). This leaves the kernel unsure what to dump for rd/hangrd cmdstream dumping. So add a MSM_SUBMIT_BO_DUMP flag so userspace can indicate buffers that contain cmdstream (or are otherwise important to dump). Signed-off-by: Rob Clark <robdclark@gmail.com>
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.
