[PATCH v4 0/2] More preparation for multi gt patches

Hi, the first of the two patches concludes the first stage of refactoring which makes the use of intel_gt on the different subsystem. It's taken from Matt's series and it has alread been reviewed. The patch has just been replaced before any multitile patches and I think it can be already pushed.

[PATCH v4 1/2] drm/i915: Store backpointer to GT in uncore

From: Michał Winiarski We now support a per-gt uncore, yet we're not able to infer which GT we're operating upon. Let's store a backpointer for now. Signed-off-by: Michał Winiarski Signed-off-by: Matt Roper Reviewed-by: Andi Shyti Signed-off-by: Andi Shyti --- drivers/gpu/drm/i915/gt/intel

[PATCH v4 2/2] drm/i915: Use to_root_gt() to refer to the root tile

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 com

[PATCH 1/2] drm/amdkfd: Use bitmap_zalloc() when applicable

'kfd->gtt_sa_bitmap' is a bitmap. So use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency. --- drivers/gpu/drm/amd/amdkfd/kfd_device.c | 12 +++

[PATCH 2/2] drm/amdkfd: Use non-atomic bitmap functions when possible

All uses of the 'kfd->gtt_sa_bitmap' bitmap are protected with the 'kfd->gtt_sa_lock' mutex. So: - prefer the non-atomic '__set_bit()' function - use the non-atomic 'bitmap_[set|clear]()' functions instead of equivalent 'for' loops. These functions can work on several bits at a tim
