ce->wa_bb_page is allocated only for graphics version 12. However __gen125_emit_bb_start() is used for any graphics version >= 12.50. For the currently supported platforms this is not an issue, but for future ones there's a mismatch causing the jump to `wa_offset + DG2_PREDICATE_RESULT_BB` to be invalid since wa_offset is not correct. As in other places in the driver, check for graphics version "greater or equal" to future-proof the support for new platforms.

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.
