Hi Joonas, I am sorry for not getting this code indent issue. The above code is just split by typing an enter due to longer than 80 characters. Are you expecting to see the code like below? The 2nd line will be longer than 80 characters in below case. If this is fine then I will change this in the next version. intel_gvt_notify_context_status(rq, INTEL_CONTEXT_SCHEDULE_OUT); > > > @@ -87,5 +87,19 @@ uint64_t intel_lr_context_descriptor(struct > > i915_gem_context *ctx, > > /* Execlists */ > > int intel_sanitize_enable_execlists(struct drm_i915_private *dev_priv, > > int enable_execlists); > > +static inline void > > +intel_gvt_notify_context_status(struct drm_i915_gem_request *rq, > > + unsigned long status) > > With that prefix, this needs to go to intel_gvt.h, where you can take > advantage of the existing #ifdef block (which should really be #if > IS_ENABLED() too). Sure. Will move to intel_gvt.h in the next version.
