From: Andi Shyti <andi.shyti@xxxxxxxxx>
The following interfaces:
i915_wedged
i915_forcewake_user
i915_gem_interrupt
i915_sseu_status
are dependent on gt values. Put them inside gt/ and drop the
"i915_" prefix name. This would be the new structure:
gt
|
+-- forcewake_user
|
+-- interrupt_info
|
+-- sseu_status
|
+-- wedge

Hi,
this patch is the first of a series that aims to refactor the
debugfs structure in the i915. Some changes will affect the
debugfs framework as well.
It has gone through a series of offline reviews mainly from
Tvrtko.
Thanks Tvrtko for the review,
Andi
Changelog
=========
v4:
- interrupt and sseu debugfs interface are moved to their own
"debugfs_gt_irq" and "debugfs_gt_sseu" files
- reset functions are renamed to reset_show/store
v3:
- better arrangement of what should stay in i915_debugfs and
what needs to be moved under gt/
- more use of the local "uncore" and "i915" variables to improve
readability
v2:
- dropped changes on "drop_caches", they were indeed irrelevant
- improved interrupt info function
