Issue seen again where engine resets fails because the engine resumes from an incorrect RING_HEAD. HEAD is still not 0 even after writing into it. This seems to be timing issue and we experimented different values from 5ms to 50ms and found out that 50ms works best based on testing. So, if write doesn't succeed at first then retry again. v2: add a comment (Andi Shyti) Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12806 Signed-off-by: Nitin Gote <nitin.r.gote@intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241217063532.2729031-1-nitin.r.gote@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 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.
