Hi,
thanks Matt for merging the first 10 patches from v8. This series contains only the last 6 patches from the previous that make use of the newly inserted to_gt() to reach the ggtt that at the end moves from the i915 structure to the gt.
I have reshuffled a bit the order of the patche (refer to the changelog) so that from this series only patch 2 remains unreviewed.
Thanks Matt and Sujaritha for the reviews.
Andi
Changelog: ========== Patchwork: https://patchwork.freedesktop.org/series/97020/
v8 -> v9: - The patch is down to the last 6 patches. - Reshuffled a bit the order, it's more intuitive to apply the changes starting from i915/gt/, i915/, i915/gem, i915/display, i915/selftests - Addressed Matt's comments in v8. - Added Matt and Sujaritha's r-b tags
v7 -> v8: - Removed patch 11 from v7 that was allocating statically the ggtt in the gt structure instead of a dynamic allocation. As Matt pointed out, we can have GT's sharing the same GGTT. - The whole i915->ggtt to gt->ggtt patch is split in 5 patches instead of one single to make it easier to review. - The last patch removes i915->ggtt and allocates the gt->ggtt with drmm_kzalloc in the early probe and mock device.
v6 -> v7: - Patch 1: add a note about the double presence of __intel_gt_init_early() and intel_gt_init_early(). - Added all Matt's r-b's for patches 2-10. - Added a patch 12 that moves the i915->ggtt into gt->ggtt.
v5 -> v6: - fixed the assignement of i915->gt->ggtt = ggtt in the mock gem device that was making use of it before.
v4 -> v5: - use to_gt() instead of to_root_gt() and use Michał work done previously. - split the /i915->gt/to_gt()/ patch in smaller chunks in order to make review easier. (Thanks Lucas)
v3 -> v4: - the intel_gt_init_early() has been split as it was causing some headaches for the order of the early initialization. The split has been done keeping in mind the coming next patch in the series that wil make this a static function.
v2 -> v3: - sed -i ... took too much freedom and changed more than it was supposed to. - fix a compile error which did not appear in my local build
v1 -> v2: - patch 2: do not use anymore the reference i915->gt but use to_root_gt(), coming from Matt Roper's patch. - fix some comments from Chris.

GGTT is currently available both through i915->ggtt and gt->ggtt, and we eventually want to get rid of the i915->ggtt one. Use to_gt() for all i915->ggtt accesses to help with the future refactoring.
During the probe of i915 the early intiialization of the gt (intel_gt_init_hw_early()) is moved prior to any access to the ggtt. This because it's in that moment we assign the ggtt to the gt and we want to do that before using it.

I think this function is looking for the GT coming from the VM, otherwise originally it could have taken it from &i915->gt. In my first version I proposed a wrapper around this but it was rejected by Lucas.
Besides, as we discussed earlier when I was proposed the static allocation, the ggtt might not always be linked to the same gt, so that I assumed that sometimes:
to_gt(perf->i915)->ggtt->vm.gt != to_gt(perf->i915)
if two GTs are sharing the same ggtt, what would the ggtt->vm.gt link be?
Thanks, Andi

Actually the most correct thing to do is probably to use 'stream->engine->gt' to ensure we grab the GT actually associated with the stream's engine.

thanks for the suggestions, but this is out of the scope of this patch... I did propose a wrapper but it was rejected because it was, indeed, out of scope.
I'm going to use to_gt(perf->i915) as Matt suggested originally, patch is ready.

From: Michał Winiarski michal.winiarski@intel.com
GGTT is currently available both through i915->ggtt and gt->ggtt, and we eventually want to get rid of the i915->ggtt one. Use to_gt() for all i915->ggtt accesses to help with the future refactoring.

I'm sending this this v10 as reply-to, if it confuses you I can send the whole v10.
The only trivial difference is that in i915_perf.c I'm using
to_gt(perf->i915)
instead of
to_gt(perf->i915)->ggtt->vm.gt

GGTT is currently available both through i915->ggtt and gt->ggtt, and we eventually want to get rid of the i915->ggtt one. Use to_gt() for all i915->ggtt accesses to help with the future refactoring.

Hi Matt,
I'm sending this this v10 as reply-to, if it confuses you I can send the whole v10.
The only trivial difference is that in i915_perf.c I'm using
to_gt(perf->i915)
instead of
to_gt(perf->i915)->ggtt->vm.gt

From: Michał Winiarski michal.winiarski@intel.com
GGTT is currently available both through i915->ggtt and gt->ggtt, and we eventually want to get rid of the i915->ggtt one. Use to_gt() for all i915->ggtt accesses to help with the future refactoring.

The reference to the GGTT from the private date is not used anymore. Remove it.
The ggtt in the root gt will now be dynamically allocated and the deallocation handled by the drmm_* managed allocation.
