[ Upstream commita6ed203587] On some OEM setups users can configure the BIOS for S3 or S2idle. When configured to S3 users can still choose 's2idle' in the kernel by using `/sys/power/mem_sleep`. Before commit6dc8265f98("drm/amdgpu: always reset the asic in suspend (v2)"), the GPU would crash. Now when configured this way, the system should resume but will use more power. As such, adjust the `amdpu_acpi_is_s0ix function` to warn users about potential power consumption issues during their first attempt at suspending.

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.
