dma-fence: Use kernel's sort for merging fences

commit fe52c649438b8489c9456681d93a9b3de3d38263 upstream.

dma-fence: Use kernel's sort for merging fences

commit fe52c649438b8489c9456681d93a9b3de3d38263 upstream.

One alternative to the fix Christian proposed in
https://lore.kernel.org/dri-devel/20241024124159.4519-3-christian.koenig@amd.com/
is to replace the rather complex open coded sorting loops with the kernel
standard sort followed by a context squashing pass.

Proposed advantage of this would be readability but one concern Christian
raised was that there could be many fences, that they are typically mostly
sorted, and so the kernel's heap sort would be much worse by the proposed
algorithm.

I had a look running some games and vkcube to see what are the typical
number of input fences. Tested scenarios:

1) Hogwarts Legacy under Gamescope

450 calls per second to __dma_fence_unwrap_merge.

Percentages per number of fences buckets, before and after checking for
signalled status, sorting and flattening:

N Before After
0 0.91%
1 69.40%
2-3 28.72% 9.4% (90.6% resolved to one fence)
4-5 0.93%
6-9 0.03%
10+

2) Cyberpunk 2077 under Gamescope

1050 calls per second, amounting to 0.01% CPU time according to perf top.

N Before After
0 1.13%
1 52.30%
2-3 40.34% 55.57%
4-5 1.46% 0.50%
6-9 2.44%
10+ 2.34%

3) vkcube under Plasma

90 calls per second.

N Before After
0
1
2-3 100% 0% (Ie. all resolved to a single fence)
4-5
6-9
10+

In the case of vkcube all invocations in the 2-3 bucket were actually
just two input fences.

From these numbers it looks like the heap sort should not be a
disadvantage, given how the dominant case is <= 2 input fences which heap
sort solves with just one compare and swap. (And for the case of one input
fence we have a fast path in the previous patch.)

A complementary possibility is to implement a different sorting algorithm
under the same API as the kernel's sort() and so keep the simplicity,
potentially moving the new sort under lib/ if it would be found more
widely useful.

v2:
* Hold on to fence references and reduce commentary. (Christian)
* Record and use latest signaled timestamp in the 2nd loop too.
* Consolidate zero or one fences fast paths.

v3:
* Reverse the seqno sort order for a simpler squashing pass. (Christian)

dma-buf: add dma_fence_timestamp helper

When a fence signals there is a very small race window where the timestamp
isn't updated yet. sync_file solves this by busy waiting for the
timestamp to appear, but on other ocassions didn't handled this
correctly.

Provide a dma_fence_timestamp() helper function for this and use it in
all appropriate cases.

Another alternative would be to grab the spinlock when that happens.

v2 by teddy: add a wait parameter to wait for the timestamp to show up, in case
the accurate timestamp is needed and/or the timestamp is not based on
ktime (e.g. hw timestamp)
v3 chk: drop the parameter again for unified handling

ASoC: Improve coverage in default KUnit runs

Merge series from Mark Brown <broonie@kernel.org>:

We have some KUnit tests for ASoC but they're not being run as much as
they should be since ASoC isn't enabled in the configs used by default
with KUnit and in the case of the topology tests there is no way to
enable them without enabling drivers that use them. This series
provides a Kconfig option which KUnit can use directly rather than worry
about drivers.

Further, since KUnit is typically run in UML but ALSA prevents build
with UML we need to remove that Kconfig conflict. As far as I can tell
the motiviation for this is that many ALSA drivers use iomem APIs which
are not available under UML and it's more trouble than it's worth to go
through and add per driver dependencies. In order to avoid these issues
we also provide stubs for these APIs so there are no build time issues
if a driver relies on iomem but does not depend on it. With these stubs
I am able to build all the sound drivers available in a UML defconfig
(UML allmodconfig appears to have substantial other issues in a quick
test).

With this series I am able to run the topology KUnit tests as part of a
kunit --alltests run.
