[v3,2/4] media: imagination: Add E5010 JPEG Encoder driver
Commit Message
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: 70, Succeeded: 70, 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
Existing V4L2 M2M based JPEG drivers namely s5p-jpeg,
imx-jpeg and rcar_jpu were referred while making this.
TODO:
Add MMU and memory tiling support

V2:
No change
V3:
- Correct license headers
- 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
- Fix unexpected indentation
- Correct commit message
- Remove dependency on ARCH_K3 as driver is not specific to that

Yes I think it should be possible to have a jpeg helpers library or a common
file for preparing jpeg headers and I am open to look into it but would prefer
to track that as a separate patch and not in this series as I want to spend
some time to design it properly.
For now, I was thinking if I can move all these byte arrays too to
include/media/jpeg.h and update it in V4 and then as a separate patch series
introduce the jpeg encoder helper module which export API to prepare JPEG helpers.
Kindly let me know your opinion.

It's the size of both chroma and luma qp_tables, maybe I can have a macro
QP_TABLE_SIZE instead of using magic numbers.

You can just do:

This can just be:
return reg & JASPER_INTERRUPT_STATUS_CR_PICTURE_DONE_IRQ_MASK;

Same here.

Just use return write_reg_field_not_busy(), same in the similar instances below.

I haven't read through the whole patch yet, but almost certainly get_queue is
only ever called with V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE or V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE.
So just simplify this:
if (type == V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE)
return &ctx->out_queue;
return &ctx->cap_queue;
Then the caller doesn't need to do any error checking, thus simplifying
the code further.

bus_info is filled in automatically for platform devices, just drop this.

No need for these two lines, the v4l2 framework will use device_caps in struct video_device
to fill this in automatically.

Hmm, this looks very much like the VIDIOC_TRY_FMT is actually updating
real values, instead of just 'trying' them.
I think this belongs in s_fmt below. Same for the other changes to
queue in this function.

And here is where the actualy updates to e5010_q_data should take place, I think.
It certainly does not make sense that s_fmt is just the same as try_fmt. That
can really only happen if there is just a single hardcoded format, and that isn't
the case here.

Ew, you are modifying a global struct.

This must be done last. As soon as you register the video device it can be
used, so registering the video device should only be done once everything
else is set up correctly.
