Chris Wilson 984cadea03 drm/i915: Allow the sysadmin to override security mitigations ... The clear-residuals mitigation is a relatively heavy hammer and under some circumstances the user may wish to forgo the context isolation in order to meet some performance requirement. Introduce a generic module parameter to allow selectively enabling/disabling different mitigations. To disable just the clear-residuals mitigation (on Ivybridge, Baytrail, or Haswell) use the module parameter: i915.mitigations=auto,!residuals Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1858 Fixes: 47f8253d2b ("drm/i915/gen7: Clear all EU/L3 residual contexts") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Jon Bloomfield <jon.bloomfield@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: stable@vger.kernel.org # v5.7 Reviewed-by: Jon Bloomfield <jon.bloomfield@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210111225220.3483-3-chris@chris-wilson.co.uk (cherry picked from commit f7452c7cbd) Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2021-01-12 19:03:40 +02:00
