drm/i915/icl: Ringbuffer interrupt handling
On Gen11 interrupt masks need to be clear to allow C6 entry. We keep them all enabled knowing that we generate extra interrupts. v2: Rebase. v3: Remove gen 11 extra check in logical_render_ring_init. v4: Rebase fixes. v5: Rebase/refactor. v6: Rebase. v7: Rebase. v8: Update comment and commit message (Daniele) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180302161501.28594-1-mika.kuoppala@linux.intel.com
