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.

This patch adds a new sysfs interface for running the cleaner shader on AMD GPUs. The cleaner shader is used to clear GPU memory before it's reused, which can help prevent data leakage between different processes. The new sysfs file is write-only and is named `run_cleaner_shader`. Write the number of the partition to this file to trigger the cleaner shader on that partition. There is only one partition on GPUs which do not support partitioning. Changes made in this patch: - Added `amdgpu_set_run_cleaner_shader` function to handle writes to the `run_cleaner_shader` sysfs file. - Added `run_cleaner_shader` to the list of device attributes in `amdgpu_device_attrs`. - Updated `default_attr_update` to handle `run_cleaner_shader`. - Added `AMDGPU_DEVICE_ATTR_WO` macro to create write-only device attributes. v2: fix error handling (Alex) Cc: Christian König <christian.koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Signed-off-by:Alex Deucher <alexander.deucher@amd.com> Signed-off-by:
