This series (or at least the suballocator helper) is a prerequisite
for the new Xe driver.
There was an unresolved issue when the series was last up for review,
and that was the per allocation aligment. Last message was from
Maarten Lankhorst arguing that the larger per-driver alignment used
would only incur a small memory cost. This new variant resolves that.
The generic suballocator has been tested with the Xe driver, and a
kunit test is under development.
The amd- and radeon adaptations are only compile-tested.
v3:
- Remove stale author information (Christian König)
- Update Radeon Kconfig (Thomas Hellström)
v4:
- Avoid 64-bit integer divisions (kernel test robot <lkp@intel.com>)
- Use size_t rather than u64 for the managed range. (Thomas)
Maarten Lankhorst (3):
drm/suballoc: Extract amdgpu_sa.c as generic suballocation helper
drm/amd: Convert amdgpu to use suballocation helper.
drm/radeon: Use the drm suballocation manager implementation.

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Suballocating a buffer object is something that is not driver-specific
and useful for many drivers.
Use a slightly modified version of amdgpu_sa.c
v2:
- Style cleanups.
- Added / Modified documentation.
- Use u64 for the sizes and offset. The code dates back to 2012 and
using unsigned int will probably soon come back to bite us.
We can consider size_t as well for better 32-bit efficiency.
- Add and document gfp, intr and align arguments to drm_suballoc_new().
- Use drm_printer for debug output.
v3:
- Remove stale author info (Christian König)
v4:
- Avoid 64-bit integer divisions (kernel test robot <lkp@intel.com>)
- Use size_t rather than u64 for the managed range. (Thomas)

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Suballocating a buffer object is something that is not driver-specific
and useful for many drivers.
Use a slightly modified version of amdgpu_sa.c
v2:
- Style cleanups.
- Added / Modified documentation.
- Use u64 for the sizes and offset. The code dates back to 2012 and
using unsigned int will probably soon come back to bite us.
We can consider size_t as well for better 32-bit efficiency.
- Add and document gfp, intr and align arguments to drm_suballoc_new().
- Use drm_printer for debug output.
v3:
- Remove stale author info (Christian König)
v4:
- Avoid 64-bit integer divisions (kernel test robot <lkp@intel.com>)
- Use size_t rather than u64 for the managed range. (Thomas)

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Suballocating a buffer object is something that is not driver-specific
and useful for many drivers.
Use a slightly modified version of amdgpu_sa.c
v2:
- Style cleanups.
- Added / Modified documentation.
- Use u64 for the sizes and offset. The code dates back to 2012 and
using unsigned int will probably soon come back to bite us.
We can consider size_t as well for better 32-bit efficiency.
- Add and document gfp, intr and align arguments to drm_suballoc_new().
- Use drm_printer for debug output.
v3:
- Remove stale author info (Christian König)
v4:
- Avoid 64-bit integer divisions (kernel test robot <lkp@intel.com>)
- Use size_t rather than u64 for the managed range. (Thomas)

Now that we have a generic suballocation helper, Use it in amdgpu.
For lines that get moved or changed, also fix up pre-existing style issues.

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Now that we have a generic suballocation helper, Use it in amdgpu.
For lines that get moved or changed, also fix up pre-existing style issues.

- * When allocating new object we first check if there is room at

- *
- * When there is not enough room at the end, we start waiting for

- * alloc_size, this object then become the sub object we return.
- *
- * Alignment can't be bigger than page size.

- *
- * When allocating new object we first check if there is room at

- *
- * When there is not enough room at the end, we start waiting for
- * each sub object until we reach object_offset+object_size >=
- * alloc_size, this object then become the sub object we return.
- *
- * Alignment can't be bigger than page size.

- * Hole are not considered for allocation to keep things simple.
