The "Run Tests on qemu" section of run_wrapper.rst had a few issues left
over from the last big documentation refactor[1]:
- It referenced a non_uml.rst page, which was integrated into the other
pages (including run_wrapper.rst).
- It skimmed over the use of --arch= and --cross_compile= in favour of
using a custom --qemu_config. Since most users will want to use the
former, let's give examples.
Remove the reference to the non-existant page, and add a couple of
examples to encourage the use of --arch= and --cross_compile=.
With this change, there should be no more broken references in the KUnit
documentation (i.e., the one mentioned in [2] is gone).

There are several tests which depend on PCI, and hence need a bunch of
extra options to run under UML. This makes it awkward to give
configuration instructions (whether in documentation, or as part of a
.kunitconfig file), as two separate, incompatible sets of config options
are required for UML and "most other architectures".
For non-UML architectures, it's possible to add default kconfig options
via the qemu_config python files, but there's no equivalent for UML. Add
a new tools/testing/kunit/configs/arch_uml.config file containing extra
kconfig options to use on UML.

It's come up a few times that it would be useful to have --kunitconfig
be repeatable [1][2].
This could be done before with a bit of shell-fu, e.g.
$ find fs/ -name '.kunitconfig' -exec cat {} + | \
./tools/testing/kunit/kunit.py run --kunitconfig=/dev/stdin
or equivalently:
$ cat fs/ext4/.kunitconfig fs/fat/.kunitconfig | \
./tools/testing/kunit/kunit.py run --kunitconfig=/dev/stdin
But this can be fairly clunky to use in practice.
And having explicit support in kunit.py opens the door to having more
config fragments of interest, e.g. options for PCI on UML [1], UML
coverage [2], variants of tests [3].
There's another argument to be made that users can just use multiple
--kconfig_add's, but this gets very clunky very fast (e.g. [2]).
Note: there's a big caveat here that some kconfig options might be
incompatible. We try to give a clearish error message in the simple case
where the same option appears multiple times with conflicting values,
but more subtle ones (e.g. mutually exclusive options) will be
potentially very confusing for the user. I don't know we can do better.
Note 2: if you want to combine a --kunitconfig with the default, you
either have to do to specify the current build_dir
> --kunitconfig=.kunit --kunitconfig=additional.config
or
> --kunitconfig=tools/testing/kunit/configs/default.config --kunitconifg=additional.config
each of which have their downsides (former depends on --build_dir,
doesn't work if you don't have a .kunitconfig yet), etc.
Example with conflicting values:
> $ ./tools/testing/kunit/kunit.py config --kunitconfig=lib/kunit --kunitconfig=/dev/stdin <<EOF
> CONFIG_KUNIT_TEST=n
> CONFIG_KUNIT=m
> EOF
> ...

We have an optimization in do_zone_finish() to send REQ_OP_ZONE_FINISH only
when necessary, i.e. we don't send REQ_OP_ZONE_FINISH when we assume we

The assumption is determined by "alloc_offset == capacity". This condition

This inconstancy results in activating another block group while we cannot

When doing a direct IO read or write, we always return -ENOTBLK when we
find a compressed extent (or an inline extent) so that we fallback to
buffered IO. This however is not ideal in case we are in a NOWAIT context
(io_uring for example), because buffered IO can block and we currently
have no support for NOWAIT semantics for buffered IO, so if we need to
fallback to buffered IO we should first signal the caller that we may
need to block by returning -EAGAIN instead.
This behaviour can also result in short reads being returned to user
space, which although it's not incorrect and user space should be able
to deal with partial reads, it's somewhat surprising and even some popular
applications like QEMU (Link tag #1) and MariaDB (Link tag #2) don't
deal with short reads properly (or at all).
The short read case happens when we try to read from a range that has a
non-compressed and non-inline extent followed by a compressed extent.
After having read the first extent, when we find the compressed extent we
return -ENOTBLK from btrfs_dio_iomap_begin(), which results in iomap to
treat the request as a short read, returning 0 (success) and waiting for
previously submitted bios to complete (this happens at
fs/iomap/direct-io.c:__iomap_dio_rw()). After that, and while at
btrfs_file_read_iter(), we call filemap_read() to use buffered IO to
read the remaining data, and pass it the number of bytes we were able to
read with direct IO. Than at filemap_read() if we get a page fault error
when accessing the read buffer, we return a partial read instead of an
-EFAULT error, because the number of bytes previously read is greater
than zero.
So fix this by returning -EAGAIN for NOWAIT direct IO when we find a
compressed or an inline extent.

But we encounter a special testcase,

So VPU report the parsed resolution, then report the eos event.
So driver should notify user to handle resolution change first,

Right now the decoder maintains two separate lists for supported pixel
formats and frame sizes. Getting the supported frame sizes for the
current set format is a bit convoluted, requiring a search through
the separate frame size list. The frame sizes are used to clamp and
align requested resolutions.
Instead, the frame size structure could be embedded inside the pixel
format structure. Getting one also gets the other. And since the
the driver already keeps pointers to the current set format, getting
the frame sizes becomes straightforward.
Do just that. Move v4l2_frmsize_stepwise inside mtk_video_fmt, and get
rid of mtk_codec_framesizes.

In commit b018be06f3 ("media: mediatek: vcodec: Read max resolution
from dec_capability"), TRY_FMT clamps the resolution to the maximum
that was previously set either by default 1080p or the limit set by a
previous S_FMT call. This does not make sense when doing TRY_FMT for
the output side, which may have different capabilities.
Instead, for the output side, find the maximum resolution based on the
pixel format requested. For the capture side, find the maximum
resolution based on the currently set output format.
The maximum resolution is found from the list of per-format frame
sizes, so the patch "media: mediatek: vcodec: dec: Fix 4K frame size
enumeration" is needed.

This partially reverts commit b018be06f3 ("media: mediatek: vcodec:
Read max resolution from dec_capability"). In this commit, the maximum
resolution ended up being a function of both the firmware capability and
the current set format.
However, frame size enumeration for output (coded) formats should not
depend on the format set, but should return supported resolutions for
the format requested by userspace.
Fix this so that the driver returns the supported resolutions correctly,
even if the instance only has default settings, or if the output format
is currently set to VP8F, which does not support 4K.
This adds an copy of special casing for !VP8 and 4K support. The other
existing copy will be removed when .max_{width,height} are removed from
|struct mtk_vcodec_ctx| in a subsequent patch.

Decouple from the imx_media_dma_buf structure defined in shared helpers
by duplicating it in the imx7-media-csi driver, along with the two small
alloc and free functions. No functional change intended.

Replace the subdev pointer stored in platform drv data with the imx7_csi
pointer. Drop a now redundant dev_set_drvdata() call.

Now that the driver doesn't use any helper that relies on the
imx_media_video_dev structure anymore, merge its fields directly in the
imx7_csi structure. Update all the users accordingly, and drop the list
field that isn't used by the driver.

The imx7_csi_media_pipeline_set_stream() function has separate branches
for the start and stop paths, surrounded by mutex lock/unlock. That is
very little shared code, inline the locking and corresponding branch in
each of the two callers.

Simplify the imx7_csi_media_pipeline_set_stream() function by passing it
the imx7_csi pointer, which avoids going from subdev to entity and back
to subdev.

To prepare for code refactoring, copy the

imx-media-utils.c. Rename the function to avoid name clashes, no
