Prefer the register read specific wait function over i915 wait_for_us(). The existing condition is quite complicated. Simplify by checking for requesters first, and determine timeout based on that. Refresh requesters in case of timeouts, should one have popped up during the wait. The downside is that this does not cut the wait short if requesters show up *during* the wait, but we're talking about 1 ms so shouldn't be an issue. v2: Refresh requesters only if there were none before (Imre) Cc: Imre Deak <imre.deak@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Link: https://lore.kernel.org/r/20250626192632.2330349-1-jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@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.
