Add logical mapping for VDBOXs. This mapping is required for split-frame workloads, which otherwise fail with 00000000-F8C53528: [GUC] 0441-INVALID_ENGINE_SUBMIT_MASK ... if the application is using the logical id to reorder the engines and then using it for the batch buffer submission. It's not a big problem on media version 11 and 12 as they have only 2 instances of VCS and the logical to physical mapping is monotonically increasing - if the application is not using the logical id. Changing it for the previous platforms allows the media driver implementation for the next ones (12.50 and above) to be the same, checking the logical id. It should also not introduce any bug for the old versions of userspace not checking the id. The mapping added here is the complete map needed by XEHPSDV. Previous platforms with only 2 instances will just use a partial map and should still work. v2: Remove static from map variable (José) Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> [ Extend the mapping to media versions 11 and 12 and give proper justification in the commit message why ] Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Acked-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220316234538.434357-2-lucas.demarchi@intel.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.
