We have already advanced that Logical Ring Contexts have their own kind
of backing objects, but everything will be better explained in the Execlists
series. For now, suffice it to say that the current backing object is only
ever used with the render ring, so we're making this fact more explicit
(which is a good reason on its own).
As for the is_initialized flag, we only use to signify that the render state
has been initialized (a.k.a. golden context, a.k.a. null context). It doesn't
mean anything for the other engines, so make that distinction obvious.
Done with the following Coccinelle patch (plus manual frobbing of the struct):
@@
struct intel_context c;
@@
- (c).obj
+ c.legacy_hw_ctx.rcs_state
@@
struct intel_context *c;
@@
- (c)->obj
+ c->legacy_hw_ctx.rcs_state
@@
struct intel_context c;
@@
- (c).is_initialized
+ c.legacy_hw_ctx.initialized
@@
struct intel_context *c;
@@
- (c)->is_initialized
+ c->legacy_hw_ctx.initialized
This Execlists prep-work patch has been suggested by Chris Wilson and Daniel
Vetter separately.
Initially, it was two separate patches:
drm/i915: Rename ctx->obj to ctx->rcs_state
drm/i915: Make it obvious that ctx->id is merely a user handle

[danvet: s/id/is_initialized/ to fix the subject and resolve a
conflict in i915_gem_context_reset. Also introduce a new lctx local
variable to avoid overtly long lines.]
