For each HW engine under GT we are adding defaults sysfs
entry to list all engine scheduler properties and its
default values. So that it will be easier for user to
fetch default values of these properties anytime to go
back to default.
For example,
DUT# cat /sys/class/drm/card1/device/tileN/gtN/engines/bcs/.defaults/
job_timeout_ms preempt_timeout_us timeslice_duration_us
where,
@job_timeout_ms: The time after which a job is removed from the scheduler.
@preempt_timeout_us: How long to wait (in microseconds) for a preemption
event to occur when submitting a new context.
@timeslice_duration_us: Each context is scheduled for execution for the
timeslice duration, before switching to the next
context.
V12:

in sysfs for better interfacing readability - Niranjana
V5 :
- Scheduling props should apply per class engine not per hardware engine - Matt
- Do not record value of job_timeout_ms if changed based on dma_fence - Matt
V4 :

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.
