Linux kernel source tree
5efc58e409
Many selftests call igt_flush_test() on cleanup. With default preemption timeout of compute engines raised to 7.5 seconds, hardcoded flush timeout of 3 seconds is too short. That results in GPU forcibly wedged and kernel taineted, then IGT abort triggered. CI BAT runs loose a part of their expected coverage. Calculate the flush timeout based on the longest preemption timeout currently configured for any engine. That way, selftest can still report detected issues as non-critical, and the GPU gets a chance to recover from preemptible hangs and prepare for fluent execution of next test cases.

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.
