Even though the initial protocontext we load onto HW has the register cleared, by the time we save it into the default image, BB_OFFSET has had the enable bit set. Reclear BB_OFFSET for each new context. Testcase: igt/i915_selftests/gt_lrc v2: Extend it for gen8. v3: BB_OFFSET is recorded per engine from Gen9 onwards Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Thomas Hellstrom <thomas.hellstrom@linux.intel.com> Signed-off-by: Karolina Drobnik <karolina.drobnik@intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/37c67abb3303852f06a570a4360addf52bf941c1.1663081418.git.karolina.drobnik@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.
