From: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com>
A range + contiguous allocation (e.g. a scanout FB confined to the
CPU-visible VRAM aperture) rounds its size up to a power of two and
requires a naturally aligned free block of that size; on a fragmented
aperture no such aligned block may exist even though enough contiguous
space is free, so the allocation fails with -ENOSPC.
The non-range contiguous path already recovers from this via
__alloc_contig_try_harder(), which stitches an exact-size span from
smaller adjacent blocks, but that fallback was unreachable once
GPU_BUDDY_RANGE_ALLOCATION was set. Give __alloc_contig_try_harder()
a [range_start, range_end) window and route the range + contiguous
case through it: each candidate placement is confined to the window
and aligned to min_block_size. Non-range callers pass [0, mm->size),
where the guards are no-ops, so the existing behaviour is unchanged.
A KUnit regression test covers the fragmentation pattern.
Resolves the igt@kms_plane@plane-panning-bottom-right@pipe-a/pipe-b
regression.
v2:
- Drop the split-undo patch; the range-bias search always descends to
an exact-order block or fails the split (already handled), so the
extra undo was redundant. (Matthew)
- Verified this fallback alone fixes the kms_plane regression.

- [High] gpu/buddy: range-restricted alloc fails when free space exceeds range_end
--
commit 2ed4c9d1a70c51390968b65e939095ce52c8ee07
Author: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com>
gpu/buddy: add range-restricted contiguous allocation fallback
A range + contiguous allocation rounds its size up to a power of two
and requires a naturally aligned free block of that size. The
non-range contiguous path already recovers from fragmentation via
__alloc_contig_try_harder(), which is now given a range window to
support the range + contiguous case.

[Severity: High]
Does this skip the left-hand side (LHS) fallback when contiguous free space
exceeds range_end?
If __gpu_buddy_alloc_range() succeeds at finding free space starting at
rhs_offset, err is 0. If the free space extends beyond range_end, the newly
added check (aligned >= range_start && aligned + size <= range_end) might
fail. But since err is still 0, it hits the unconditional goto next.
By skipping to next, doesn't this bypass the LHS window-sliding logic below?
If there was valid free space to the left of rhs_offset that perfectly fits
the window, it appears it would be ignored, causing the allocator to return
-ENOSPC despite sufficient space existing within the requested range.

Patch looks more like totally new functionally/feature, so the fixes
here is maybe unexpected? Did something in that fixes commit change
something such that the try_harder is now needed, but that needs some
expansion with bias + contig? Do we know exactly what changed here?

Did you consider doing a bias-range for [start, end] using
min_block_size and using what it returns as the starting point,
extending left/right? If that fails advance start and try again? Maybe
what you have here is much better for the case you have in mind?

That commit removed __force_merge(), which previously helped recover
larger contiguous allocations on demand. As a result, some
range-restricted contiguous allocation requests
that used to succeed now fail with -ENOSPC (the kms_plane regression).
This patch restores that capability through the try_harder() stitching
logic, so the Fixes: tag reflects a
regression introduced by that commit rather than new functionality.

I took a closer look at the alloc_range_bias approach. My understanding
is that this would repeatedly bias within [start, end], use the returned
min_block_size block as a starting point, and then extend left/right to
build the requested run.
While that should work, every failed attempt may require splitting
higher-order blocks to obtain a min_block_size block, followed by a
free/merge back when the extension fails.
The free-tree descent evaluates the available starting points through a
tree walk without any splitting or allocation just for enumeration, so I
kept that approach.
Please let me know if there is a case where alloc_range_bias would
provide an advantage over the free-tree descent.
While evaluating it, I found two issues in the current try_harder()
implementation:
1. It only searches free_tree[size_order]. This is insufficient when
min_block_size < size. For example, for a 128 KiB allocation (order-5)
with min_block_size = 4 KiB, free_tree[5] may be empty
while two adjacent order-4 (64 KiB) blocks covering [64 KiB, 128 KiB]
and [128 KiB, 192 KiB] are free. These blocks still form a valid
order-5-sized contiguous run, but they can never appear in
free_tree[5] because they are not mergeable buddies. As a result, a
search that only considers free_tree[5] will never find this placement.
v3 addresses this by walking the free tree from the
requested size order down to min_order, while reusing the existing
extend/stitch logic and min_block_size alignment checks unchanged.
2. The search is not restricted to the requested range. v3 confines the
walk to [range_start, range_end], skipping candidates at or above
range_end and stopping once the walk falls below range_start.
This ensures that range-constrained allocations only consider free
blocks within the requested window and avoids performing allocation/free
attempts on blocks outside the specified range.
For non-range callers, the effective window remains [0, mm->size], so
the behavior is unchanged.
Regards,
Arun.

__force_merge() got nuked, but IIRC I think that was essentially because
we now "force merge" on free, so shouldn't we get the ~same result? Or
is the fact that we force_merge() on every free giving a different
layout of pages, and with some very some specific allocation pattern
that difference subtly results in -ENOSPC, somehow?

You are right - merge-on-free reclaims contiguity just like the old
on-demand __force_merge() , so that is not the cause and the layout is
effectively the same. The real change is where clear/dirty segregation
lives: it used to be an inline guard inside __alloc_range_bias() , but
the rework pulled it out into dirty_steer_window() , which only runs for
non-range allocations. So range (aperture) requests now go through
__alloc_range_bias() with no clear/dirty guard at all - clear and dirty
allocations interleave and fragment the aperture until no large
same-class run survives for a 4K scanout pin (-> -ENOSPC). Restoring
that two-pass guard is the real fix.
I have accordingly moved the Fixes: tag onto that guard-restore patch,
and kept the range support in __alloc_contig_try_harder() as a new
feature - it still helps, but it is a safety-net fallback that should
land on top, not as the root-cause fix.
Regards,
Arun.
