Starting from a patch from Matt to_root_gt() returns the
reference to the root tile in order to abstract the root tile
from th callers.
Being the root tile identified as tile '0', embed the id in the
name so that i915->gt becomes i915->gt0.
The renaming has been mostly done with the following command and
some manual fixes.
sed -i -e sed -i 's/\&i915\->gt\./\&to_root_gt(i915)\->/g' \
-e sed -i 's/\&dev_priv\->gt\./\&to_root_gt(dev_priv)\->/g' \
-e 's/\&dev_priv\->gt/to_root_gt(dev_priv)/g' \
-e 's/\&i915\->gt/to_root_gt(i915)/g' \
-e 's/dev_priv\->gt\./to_root_gt(dev_priv)\->/g' \
-e 's/i915\->gt\./to_root_gt(i915)\->/g' \
`find drivers/gpu/drm/i915/ -name *.[ch]`
Two small changes have been added to this commit:
1. intel_reset_gpu() in intel_display.c retreives the gt from
to_scanout_gt()
2. in set_scheduler_caps() the gt is taken from the engine and
not from i915.
Ideally the non-automatic changes should be in separate patches, before
the ones that can be done by automation. Because then it becomes easier
to apply the final result without conflicts.
This is quite a big diff to merge in one go. Looking at the pending
patches from Michal however I see he had similar changes, split in
sensible chunks.. Could you split your version like that? at least
gt/gem and display would be good to have separate. Or sync with Michal
on how to proceed with these versions Here are his patches:
drm/i915: Remove i915->ggtt
drm/i915: Use to_gt() helper for GGTT accesses
drm/i915: Use to_gt() helper
drm/i915/gvt: Use to_gt() helper
drm/i915/gem: Use to_gt() helper
drm/i915/gt: Use to_gt() helper
drm/i915/display: Use to_gt() helper
drm/i915: Introduce to_gt() helper
This first patch also removed the `struct intel_gt *gt = to_gt(pool)`,
that would otherwise be a leftover in
drivers/gpu/drm/i915/gt/intel_gt_buffer_pool.c
