[Patch v4 00/11] Add MFC V12 support

[Patch v4 00/11] Add MFC V12 support

[Aakarsh Jain]

This patch series adds MFC v12 support. MFC v12 is used in Tesla FSD SoC.

This adds support for following:

-Add support for YV12 and I420 format (3-plane)
-Add support for Rate Control, UHD and DMABUF for encoder
-Add support for DPB buffers allocation based on MFC requirement

Changes since v3:
-Removed vp9 codec support for now and just keeping MFC v12 base
patches with necessary hardware controls, decoder, encoder and
structural changes. Also covers luma dbp, chroma dpb and mv sizes
for each codec as per the UM for MFCv12, along with appropriate
alignment.
v3 link: https://patchwork.kernel.org/project/linux-media/cover/20221011122516.32135-1-aakarsh.jain@samsung.com/

Changes since v2:
-Addressed review comments by Rob Herring.
This was regarding the errors found by Rob bot in yaml file. File
'samsung,s5p-mfc.yaml' is already converted into json schema and is
merged.

-Addressed review comments by Krzysztof Kozlowski.
This was regarding depricated properties mentioned in s5p-mfc.txt file.
Review comment was addressed and 'samsung,s5p-mfc.yaml' is already
merged now.

-Addressed review comments by Andi Shyti.
This was regarding addition of 'MFC_V10PLUS_BITS' macro in
's5p_mfc_common.h file.

Separated bug fixes patches, resent again with fix tag
and those are merged now.
-Added SoC based compatible string.

[Patch v4 02/11] media: s5p-mfc: Rename IS_MFCV10 macro

[Aakarsh Jain]

Renames macro IS_MFCV10 to IS_MFCV10_PLUS so that the MFCv10 code can
be resued for MFCv12 support. Since some part of MFCv10 specific code
holds good for MFCv12 also.

[Patch v4 02/11] media: s5p-mfc: Rename IS_MFCV10 macro

[Aakarsh Jain]

Renames macro IS_MFCV10 to IS_MFCV10_PLUS so that the MFCv10 code can
be resued for MFCv12 support. Since some part of MFCv10 specific code
holds good for MFCv12 also.

[Patch v4 03/11] media: s5p-mfc: Add initial support for MFCv12

[Aakarsh Jain]

Add support for MFCv12, with a new register file and necessary hw
control, decoder, encoder and structural changes. Add luma dbp, chroma
dpb and mv sizes for each codec as per the UM for MFCv12, along with
appropriate alignment.

[Patch v4 03/11] media: s5p-mfc: Add initial support for MFCv12

[Aakarsh Jain]

Add support for MFCv12, with a new register file and necessary hw
control, decoder, encoder and structural changes. Add luma dbp, chroma
dpb and mv sizes for each codec as per the UM for MFCv12, along with
appropriate alignment.

[Patch v4 04/11] media: s5p-mfc: Add YV12 and I420 multiplanar format support

[Aakarsh Jain]

YV12 and I420 format (3-plane) support is added. Stride information is
added to all formats and planes since it is necessary for YV12/I420
which are different from width.

[Patch v4 04/11] media: s5p-mfc: Add YV12 and I420 multiplanar format support

[Aakarsh Jain]

YV12 and I420 format (3-plane) support is added. Stride information is
added to all formats and planes since it is necessary for YV12/I420
which are different from width.

[Patch v4 06/11] media: s5p-mfc: Add support for UHD encoding.

[Aakarsh Jain]

MFC driver had restriction on max resolution of 1080p, updated it for
UHD. Added corresponding support to set recommended profile and level
for H264 in UHD scenario.

[Patch v4 08/11] media: s5p-mfc: Set context for valid case before calling try_run

[Aakarsh Jain]

Context bit is set for hardware execution if there is a buffer in
source and destination queue before calling try_run in the
init_buffers function. Now there will be a new context created and
hardware will be invoked for the buffer queued instead of waiting for
another buffer to be queued from userspace to set this context bit for
hw execution.

[Patch v4 10/11] media: s5p-mfc: DPB Count Independent of VIDIOC_REQBUF

[Aakarsh Jain]

Add allocation of DPB buffers based on MFC requirement so,
codec buffers allocations has been moved after state
MFCINST_HEAD_PRODUCED. It is taken care that codec buffer allocation
is performed in process context from userspace IOCTL call.

No changelog and your cover letter does not explain what happened here.
Specifically, why did you decide to ignore received tag.

That's odd. How so? MFC v12 does not support IOMMU?

Last patch series we had two different patches for schema which was one for adding MFCv12 compatible string and other for adding its HW properties.
In one of the patches you gave reviewed-by tag. Since mfc dt_schema got merged already, and this is relatively  new patch so thought of getting reviewed again.

Link to those patches:
https://patchwork.kernel.org/project/linux-media/patch/20221011122516.32135-2-aakarsh.jain@samsung.com/
https://patchwork.kernel.org/project/linux-media/patch/20221011122516.32135-3-aakarsh.jain@samsung.com/    

if you are ok, I will add your reviewed-by in next patch series.

MFC v12 do support IOMMU. But currently it is not enabled in SW (has dependencies on some of the floating dma-mapping patches) and not tested on upstream kernel. Current patch sets intend to add support for MFCv12 using reserve memory and later patches related to enable iommu will be posted (after resolving the dependencies). So I marked iommu property as false. 
Now what is your suggestion here? Should I keep iommu as false or add memory-region as below?
Ex-
  - if:
      properties:
        compatible:
          contains:
            enum:
              - tesla,fsd-mfc
    then:
      properties:
        clocks:
          maxItems: 1
        clock-names:
          items:
            - const: mfc
        memory-region:
          maxItems: 1

Last patch series we had two different patches for schema which was one for adding MFCv12 compatible string and other for adding its HW properties.
In one of the patches you gave reviewed-by tag. Since mfc dt_schema got merged already, and this is relatively  new patch so thought of getting reviewed again.

Link to those patches:
https://patchwork.kernel.org/project/linux-media/patch/20221011122516.32135-2-aakarsh.jain@samsung.com/
https://patchwork.kernel.org/project/linux-media/patch/20221011122516.32135-3-aakarsh.jain@samsung.com/    

if you are ok, I will add your reviewed-by in next patch series.

It is okay to drop Reviewed-by tag, but this should be explicitly
mentioned in the changelog with a reason.

I expect complete picture of the hardware, not something limited to
current driver, so for sure iommus must be there.

Huh? This is very weird. This definitely deserves a comment in the actual
code rather than just the commit log.

Do you know what is going on? What part is updated? Are you sure it isn't
a driver bug somehow?

I don't usually interfere, this is your driver to maintain, but this becomes
horribly messy. Have you consider de-hardcoding a little and encapsulate per HW
format details into a C structure ? Drivers these days try to make sure of v4l2-
common library, which as a matter of fact knows that YUV420M and YVU420M have 3
places, so that you don't have to duplicate it in your driver.

regards,
Nicolas

I don't usually interfere, this is your driver to maintain, but this becomes
horribly messy. Have you consider de-hardcoding a little and encapsulate per HW
format details into a C structure ? Drivers these days try to make sure of v4l2-
common library, which as a matter of fact knows that YUV420M and YVU420M have 3
places, so that you don't have to duplicate it in your driver.

regards,
Nicolas

Thanks for pointing out.
We could have done it in this way ' *plane_count = ctx->dst_fmt->num_planes' also.
Anyway, will make use of ' v4l2- common library ' for getting the planes count here in next series.

Thanks for the review.

Thanks for pointing out.
We could have done it in this way ' *plane_count = ctx->dst_fmt->num_planes' also.
Anyway, will make use of ' v4l2- common library ' for getting the planes count here in next series.

Thanks for the review.

During SYS_INIT command sent to MFC sequentially, firmware is not able to initialize the hardware due to incorrect firmware transfer and in current scenario the firmware is not loaded again in the Reserved memory area.
In this case RET_SYS_INIT response from hardware is failing. So we need to load firmware every time we open the device node.
I will add comment in the code why this change is needed.

Thanks for the review.

During SYS_INIT command sent to MFC sequentially, firmware is not able to initialize the hardware due to incorrect firmware transfer and in current scenario the firmware is not loaded again in the Reserved memory area.
In this case RET_SYS_INIT response from hardware is failing. So we need to load firmware every time we open the device node.
I will add comment in the code why this change is needed.

Thanks for the review.
