Linux kernel source tree

For long running (LR) jobs with the DRM scheduler we must return NULL in run_job which results in signaling the job's finished fence immediately. This prevents LR jobs from creating infinite dma-fences. Signaling job's finished fence immediately breaks flow controlling ring with the DRM scheduler. To work around this, the ring is flow controlled and written in the exec IOCTL. Signaling job's finished fence immediately also breaks the TDR which is used in reset / cleanup entity paths so write a new path for LR entities. v2: Better commit, white space, remove rmb(), better comment next to emit_job() v3 (Thomas): Change LR reference counting, fix working in commit Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.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.
