Media userspace was the last userspace to still use them, and they converted now too:144020c377This means no reason anymore to make relocations faster than they've been for the first 9 years of gem. This code was added in commit7dd4f6729fAuthor: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jun 16 15:05:24 2017 +0100 drm/i915: Async GPU relocation processing Furthermore there's pretty strong indications it's buggy, since the code to use it by default as the only option had to be reverted: commitad5d95e4d5Author: Dave Airlie <airlied@redhat.com> Date: Tue Sep 8 15:41:17 2020 +1000 Revert "drm/i915/gem: Async GPU relocations only" This code just disables gpu relocations, leaving the garbage collection for later patches and more importantly, much less confusing diff. Also given how much headaches this code has caused in the past, letting this soak for a bit seems justified.

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.
