Context save handling needs to be updated for a multi XCC setup: - On a multi XCC setup, KFD needs to report context save base address and size for each XCC in MQD. - Thunk will allocate a large context save area covering all XCCs which will be equal to: num_of_xccs in a partition * size of context save area for 1 XCC. However, it will report only the size of context save area for 1 XCC only in the ioctl call. - Driver then setups the MQD correctly using the size passed from Thunk and information about number of XCCs in a partition. - Update get_wave_state function to return context save area for all XCCs in the partition. v2: update the get_wave_state function for mqd manager v11 (Morris) Signed-off-by: Mukul Joshi <mukul.joshi@amd.com> Tested-by: Amber Lin <Amber.Lin@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Morris Zhang <Shiwu.Zhang@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 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.
