Add dt-bindings for Imagination E5010 JPEG Encoder [1] which is implemented
as stateful V4L2 M2M driver.
The device supports baseline encoding with two different quantization
tables and compression ratio as demanded.
Minimum resolution supported is 64x64 and Maximum resolution supported is
8192x8192.

This adds support for stateful V4L2 M2M based driver for Imagination E5010
JPEG Encoder [1] which supports baseline encoding with two different
quantization tables and compression ratio as demanded.
Support for both contiguous and non-contiguous YUV420 and YUV422 semiplanar
formats is added along with alignment restrictions as required by the
hardware.
System and runtime PM hooks are added in the driver along with v4l2 crop
and selection API support.
Minimum resolution supported is 64x64 and
Maximum resolution supported is 8192x8192.
All v4l2-compliance tests are passing [2] :
v4l2-compliance -s -f -a -d /dev/video0 -e /dev/video1
Total for e5010 device /dev/video0: 79, Succeeded: 79, Failed: 0,
Warnings: 0
NOTE: video1 here is VIVID test pattern generator
Also tests [3] were run manually to verify below driver features:
- Runtime Power Management
- Multi-instance JPEG Encoding
- DMABUF import, export support
- NV12, NV21, NV16, NV61 video format support
- Compression quality S_CTRL
- Cropping support using S_SELECTION
Existing V4L2 M2M based JPEG drivers namely s5p-jpeg, imx-jpeg and rcar_jpu
were referred while making this.

Add MMU and memory tiling support

assignments in probe()
- Remove unrequired checks from queue_setup function
- Return queued buffers back if start_streaming fails
- Use ARRAY_SIZE in place of hard-coding
- Use huffman and quantization tables from reference header file
V3:

- Use more generic name core instead of jasper for base registers
- Add Comment for forward declarations
- Simplify quantization table calculations
- Use v4l2_apply_frmsize_constraints for updating framesize and remove
unrequired functions
- Place TODO at top of file and in commit message too
- Use dev_err_probe helper in probe function
- Fix return value checking for failure scenarios in probe function
- Use v4l2_err/info/warn helpers instead of dev_err/info/warn helpers

Export reference quantization and huffman tables as provided in ITU-T.81 so
that they can be re-used by other JPEG drivers.
These are example tables provided in ITU-T.81 as reference tables and the
JPEG encoders are free to use either these or their own proprietary tables.
Also add necessary prefixes to be used for huffman tables in global header
file.

Add below rounding related macros:
round_closest_up(x, y) : Rounds x to closest multiple of y where y is a
power of 2, with a preference to round up in case two nearest values are
possible.
round_closest_down(x, y) : Rounds x to closest multiple of y where y is a
power of 2, with a preference to round down in case two nearest values are
possible.
roundclosest(x, y) : Rounds x to closest multiple of y, this macro should
generally be used only when y is not multiple of 2 as otherwise
round_closest* macros should be used which are much faster.
Examples:
* round_closest_up(17, 4) = 16
* round_closest_up(15, 4) = 16
* round_closest_up(14, 4) = 16
* round_closest_down(17, 4) = 16
* round_closest_down(15, 4) = 16
* round_closest_down(14, 4) = 12
* roundclosest(21, 5) = 20
* roundclosest(19, 5) = 20
* roundclosest(17, 5) = 15

NOTE: This patch is inspired from the Mentor Graphics IPU driver [1]
which uses similar macro locally and which is updated in further patch
in the series to use this generic macro instead along with other drivers
having similar requirements.

My bad. Yes I would remove the blank line here. This is picked up as warning
from kernel-doc too.

The file math.h is not rendered as part of kernel-doc right now. I can put
this under Documentation/core-api/kernel-api.rst perhaps I can create a new
section as below:
Rounding, absolute diff and 32bit division macros
-------------------------------------------------
under the section:
CRC and Math Functions in Linux
===============================
is that okay ?

This is up to you, but what I meant is that you always can render manually
yourself. And I was asking about the result you got when you tried (and you
did, right?) to render to man, html, and pdf.

From: Daniel Latypov <dlatypov@google.com>
Add basic test coverage for files that don't require any config options:
* part of math.h (what seem to be the most commonly used macros)
* gcd.c
* lcm.c
* int_sqrt.c
* reciprocal_div.c
(Ignored int_pow.c since it's a simple textbook algorithm.)
These tests aren't particularly interesting, but they
* provide short and simple examples of parameterized tests
* provide a place to add tests for any new files in this dir
* are written so adding new test cases to cover edge cases should be
easy
* looking at code coverage, we hit all the branches in the .c files

[devarsht: Rebase to 6.9, remove kernel.h and change license to GPL]
Signed-off-by: Devarsh Thakkar <devarsht@ti.com>
---
Changes since v8:
* Remove unrequired header file linux/kernel.h
Changes since v7:
* Rebase to linux-next, change license to GPL as suggested by checkpatch.
Changes since v6:
* No change
Changes since v5:
* add in test cases for roundup/rounddown
* address misc comments from David
Changes since v4:
* add in test cases for some math.h macros (abs, round_up/round_down,
div_round_down/closest)
* use parameterized testing less to keep things terser
Changes since v3:
* fix `checkpatch.pl --strict` warnings
* add test cases for gcd(0,0) and lcm(0,0)
* minor: don't test both gcd(a,b) and gcd(b,a) when a == b
Changes since v2: mv math_test.c => math_kunit.c
Changes since v1:
* Rebase and rewrite to use the new parameterized testing support.
* misc: fix overflow in literal and inline int_sqrt format string.
* related: commit 1f0e943df68a ("Documentation: kunit: provide guidance
for testing many inputs") was merged explaining the patterns shown here.
* there's an in-flight patch to update it for parameterized testing.

The module.h is already included under include/kunit/test.h and that's the
reason compiler did not give any error. But I can still include it under
math.h for better readability as you suggested as anyway compiler will not
re-include if already included by another header file.
Also I see we were missing a dependency between math_kunit and kunit modules,
so adding a dependency there too.

I did compile and test this, so math.h was indirectly getting included via
some other header file already included but I would not rely on that and
include math.h separately as you suggested.

Indeed, it gives below logs, let me add that too.

Please, follow the IWYU principle, what you are suggesting is a fragile

Add tests for round_closest_up/down and roundclosest macros which round
to nearest multiple of specified argument. These are tested with kunit
tool as shared here [1].

If neither of the flags to round down (V4L2_SEL_FLAG_LE) or round up
(V4L2_SEL_FLAG_GE) are specified by the user, then round to nearest
multiple of requested value while updating the crop rectangle coordinates.
Use the rounding macro which gives preference to rounding down in case two
nearest values (high and low) are possible to raise the probability of
cropping rectangle falling inside the bound region.
This complies with the VIDIOC_G_SELECTION, VIDIOC_S_SELECTION ioctl
description as documented in v4l uapi [1] which specifies that driver
should choose crop rectangle as close as possible if no flags are passed by
user-space, as quoted below :
"``0`` - The driver can adjust the rectangle size freely and shall choose a
crop/compose rectangle as close as possible to the requested
one."

Use generic macro round_closest_up() for rounding closest to specified
value instead of using local macro round_closest().
There is no change from functionality point of view as round_closest_up()
is functionally same as the previously used local macro round_closest().
