Linux kernel source tree
2989184215
This patch introduces new function pointers in the amdgpu_sdma structure to handle queue stop, start and soft reset operations. These will replace the older callback mechanism. The new functions are: - stop_kernel_queue: Stops a specific SDMA queue - start_kernel_queue: Starts/Restores a specific SDMA queue - soft_reset_kernel_queue: Performs soft reset on a specific SDMA queue v2: Update stop_queue/start_queue function paramters to use ring pointer instead of device/instance(Chritian) v3: move stop_queue/start_queue to struct amdgpu_sdma_instance and rename them. (Alex) v4: rework the ordering a bit (Alex) Suggested-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.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.
