Keep subject as "drm/i915" as this is generic change. Also I saw
i915_runtime_pm_status debugfs output not updated.
Could you please check.

I did not change the seq_puts message of i915_runtime_pm_status debugfs
since it doesn't fit into the unified "early return" pattern.

We currently have two module parameters that control GuC: "enable_guc_loading" and "enable_guc_submission".
Whenever we need i915_modparams.enable_guc_submission=1, we also need enable_guc_loading=1.
We also need enable_guc_loading=1 when we want to verify the HuC,
which is every time we have a HuC (but all platforms with HuC have a GuC and viceversa).

be only HAS_GUC.

This change can be a new patch and since this/most of the patch is
depending on Michal's series I would suggest to post the series once
that gets merged.

Can we say option in the message - "Ignoring GuC submission enable
option, no hardware"
split the message over two lines.

this return is not aligned properly. code indentation needs to updated.
please run "scripts/checkpatch.pl --strict" on all patches that helps
identify such issues faster.

Overall patch logic looks fine. Will need some more updates/rebase later
as suggested.

The Additional Data Struct (ADS) contains objects that are required by
guc post FW load and are not necessarily submission-only (although that's
our current only use-case). If in the future we load GuC with submission
disabled to use some other GuC feature we might still end up requiring
something inside the ADS, so it makes more sense for them to be always
created if GuC is loaded.
Similarly, we still want to access GuC logs even if GuC submission is
disable to debug issues with GuC loading or with wathever we're using
GuC for.
To make a concrete example, the pages used by GuC to save state during
suspend are allocated as part of the ADS.
v3: Group initialization of GuC objects
v2: Decoupling ADS together with logs
v3: Re-factoring code as per review (Michal)
v4: Rebase
v5: Separating group object initialization into next patch
Clarifying commit message
v6: Reverting to goto err format (Michal)
Moved guc_ads functions to dedicated file
Rebase
