On gen7 and gen7.5 devices, there could be leftover data residuals in EU/L3 from the retiring context. This patch introduces workaround to clear that residual contexts, by submitting a batch buffer with dedicated HW context to the GPU with ring allocation for each context switching. This security mitigation changes does not triggers any performance regression. Performance is on par with current drm-tips. v2: Add igt generated header file for CB kernel assembled with Mesa tool and addressed use of Kernel macro for ptr_align comment. v3: Resolve Sparse warnings with newly generated, and imported CB kernel. v4: Include new igt generated CB kernel for gen7 and gen7.5. Also add code formatting and compiler warnings changes (Chris Wilson) Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Signed-off-by: Prathap Kumar Valsan <prathap.kumar.valsan@intel.com> Signed-off-by: Akeem G Abodunrin <akeem.g.abodunrin@intel.com> Cc: Chris Wilson <chris.p.wilson@intel.com> Cc: Balestrieri Francesco <francesco.balestrieri@intel.com> Cc: Bloomfield Jon <jon.bloomfield@intel.com> Cc: Dutt Sudeep <sudeep.dutt@intel.com> Acked-by: Chris Wilson <chris@chris-wilso.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200306000957.2836150-2-chris@chris-wilson.co.uk |

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.
