[PATCH v20 1/8] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

[jason-jh.lin]

1. Add mt8195 mmsys compatible for 2 vdosys.
2. Add io_start into each driver data of mt8195 vdosys.
3. Add get match data function to identify mmsys by io_start.
4. Add mt8195 routing table settings of vdosys0.

[PATCH v20 1/8] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

[jason-jh.lin]

1. Add mt8195 mmsys compatible for 2 vdosys.
2. Add io_start into each driver data of mt8195 vdosys.
3. Add get match data function to identify mmsys by io_start.
4. Add mt8195 routing table settings of vdosys0.

I'm not very happy with the approach of testing against the reg property to 
decide which version of the two mmsys devices we are probing. I think a better 
approach would be, if we would have added some mediatek specific ID to the 
device tree binding (or use a two compatibles?).

But as we are at v20 I think it wouldn't be fair to ask for such an instrusive 
change. So I'll take this patch now, but maybe we can discuss if we can't do 
better in a follow-up patch. Especially I don't think it's a good approach to 
check for the io_start in the DRM driver. Couldn't we pass the information about 
which of the two mmsys blocks we are calling from through the mediatek-drm 
platform device spefic data?

I also had a look into the vdosys1 series to better understand why we need to do 
things as we do them. But honestly I wasn't able to really understand the 
implication of the patch that adds 'multi mmsys support' [1]. For this looks 
like a several patches that got squashed into one. But as I don't have to 
maintain that it is not my call to complain, the patch has the needed reviews.

For this patch, now applied to v5.18-next/soc

Thanks for all people implicated.

Regards,
Matthias

I'm not very happy with the approach of testing against the reg property to 
decide which version of the two mmsys devices we are probing. I think a better 
approach would be, if we would have added some mediatek specific ID to the 
device tree binding (or use a two compatibles?).

But as we are at v20 I think it wouldn't be fair to ask for such an instrusive 
change. So I'll take this patch now, but maybe we can discuss if we can't do 
better in a follow-up patch. Especially I don't think it's a good approach to 
check for the io_start in the DRM driver. Couldn't we pass the information about 
which of the two mmsys blocks we are calling from through the mediatek-drm 
platform device spefic data?

I also had a look into the vdosys1 series to better understand why we need to do 
things as we do them. But honestly I wasn't able to really understand the 
implication of the patch that adds 'multi mmsys support' [1]. For this looks 
like a several patches that got squashed into one. But as I don't have to 
maintain that it is not my call to complain, the patch has the needed reviews.

For this patch, now applied to v5.18-next/soc

Thanks for all people implicated.

Regards,
Matthias

I'm not very happy with the approach of testing against the reg property to 
decide which version of the two mmsys devices we are probing. I think a better 
approach would be, if we would have added some mediatek specific ID to the 
device tree binding (or use a two compatibles?).

But as we are at v20 I think it wouldn't be fair to ask for such an instrusive 
change. So I'll take this patch now, but maybe we can discuss if we can't do 
better in a follow-up patch. Especially I don't think it's a good approach to 
check for the io_start in the DRM driver. Couldn't we pass the information about 
which of the two mmsys blocks we are calling from through the mediatek-drm 
platform device spefic data?

I also had a look into the vdosys1 series to better understand why we need to do 
things as we do them. But honestly I wasn't able to really understand the 
implication of the patch that adds 'multi mmsys support' [1]. For this looks 
like a several patches that got squashed into one. But as I don't have to 
maintain that it is not my call to complain, the patch has the needed reviews.

For this patch, now applied to v5.18-next/soc

Thanks for all people implicated.

Regards,
Matthias

I'm not very happy with the approach of testing against the reg property to 
decide which version of the two mmsys devices we are probing. I think a better 
approach would be, if we would have added some mediatek specific ID to the 
device tree binding (or use a two compatibles?).

But as we are at v20 I think it wouldn't be fair to ask for such an instrusive 
change. So I'll take this patch now, but maybe we can discuss if we can't do 
better in a follow-up patch. Especially I don't think it's a good approach to 
check for the io_start in the DRM driver. Couldn't we pass the information about 
which of the two mmsys blocks we are calling from through the mediatek-drm 
platform device spefic data?

I also had a look into the vdosys1 series to better understand why we need to do 
things as we do them. But honestly I wasn't able to really understand the 
implication of the patch that adds 'multi mmsys support' [1]. For this looks 
like a several patches that got squashed into one. But as I don't have to 
maintain that it is not my call to complain, the patch has the needed reviews.

For this patch, now applied to v5.18-next/soc

Thanks for all people implicated.

Regards,
Matthias

Re: [PATCH v20 1/8] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

Hi Matthias,

Thanks for the reviews.

We uses two compatibles in previous version(before v16) of this series.

https://patchwork.kernel.org/project/linux-mediatek/patch/20220307032859.3275-5-jason-jh.lin@mediatek.com/

Since we received the comment of VPPSYS from Rob:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220117055254.9777-15-roy-cw.yeh@mediatek.com/#24707362

we're trying to figure out the way to use the same compatible for
different mmsys.

But we can't find a suitable property to identify the different mmsys
directly.


In mt8195, 2 pipelines are binding to different mmsys, such as vdosys0
and vdosys1. Each mmsys uses different clock drivers and different
power domain.

Since each mmsys has its own clock, I have tried to differentiate
vdosys0, vdosys1 by the clock names:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220407030409.9664-4-jason-jh.lin@mediatek.com/
But it seems not robust enough.

Then we refer to this io_start solution, the idea from Angelo:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c?h=next-20220408#n789


I'm not sure if there is another more suitable idea to fit in this
problem.
But I believe, if using different compatibles for each mmsys is
acceptable, then we can keep the original compatible method for
mediatek-drm and mmsys, and also make these works easier.

If you have any ideas to simplify it, please help us :-)
Thanks for your reviews again.

Jason-JH.Lin

Re: [PATCH v20 1/8] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

Hi Matthias,

Thanks for the reviews.

We uses two compatibles in previous version(before v16) of this series.

Since we received the comment of VPPSYS from Rob:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220117055254.9777-15-roy-cw.yeh@mediatek.com/#24707362

we're trying to figure out the way to use the same compatible for
different mmsys.

But we can't find a suitable property to identify the different mmsys
directly.


In mt8195, 2 pipelines are binding to different mmsys, such as vdosys0
and vdosys1. Each mmsys uses different clock drivers and different
power domain.

Since each mmsys has its own clock, I have tried to differentiate
vdosys0, vdosys1 by the clock names:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220407030409.9664-4-jason-jh.lin@mediatek.com/
But it seems not robust enough.

Then we refer to this io_start solution, the idea from Angelo:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c?h=next-20220408#n789


I'm not sure if there is another more suitable idea to fit in this
problem.
But I believe, if using different compatibles for each mmsys is
acceptable, then we can keep the original compatible method for
mediatek-drm and mmsys, and also make these works easier.

If you have any ideas to simplify it, please help us :-)
Thanks for your reviews again.

Re: [PATCH v20 1/8] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

Hi Matthias,

Thanks for the reviews.

We uses two compatibles in previous version(before v16) of this series.

https://patchwork.kernel.org/project/linux-mediatek/patch/20220307032859.3275-5-jason-jh.lin@mediatek.com/

Since we received the comment of VPPSYS from Rob:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220117055254.9777-15-roy-cw.yeh@mediatek.com/#24707362

we're trying to figure out the way to use the same compatible for
different mmsys.

But we can't find a suitable property to identify the different mmsys
directly.


In mt8195, 2 pipelines are binding to different mmsys, such as vdosys0
and vdosys1. Each mmsys uses different clock drivers and different
power domain.

Since each mmsys has its own clock, I have tried to differentiate
vdosys0, vdosys1 by the clock names:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220407030409.9664-4-jason-jh.lin@mediatek.com/
But it seems not robust enough.

Then we refer to this io_start solution, the idea from Angelo:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c?h=next-20220408#n789


I'm not sure if there is another more suitable idea to fit in this
problem.
But I believe, if using different compatibles for each mmsys is
acceptable, then we can keep the original compatible method for
mediatek-drm and mmsys, and also make these works easier.

If you have any ideas to simplify it, please help us :-)
Thanks for your reviews again.

https://patchwork.kernel.org/project/linux-mediatek/patch/20220117055254.9777-15-roy-cw.yeh@mediatek.com/#24707362

we're trying to figure out the way to use the same compatible for
different mmsys.

But we can't find a suitable property to identify the different mmsys
directly.


In mt8195, 2 pipelines are binding to different mmsys, such as vdosys0
and vdosys1. Each mmsys uses different clock drivers and different
power domain.

Since each mmsys has its own clock, I have tried to differentiate
vdosys0, vdosys1 by the clock names:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220407030409.9664-4-jason-jh.lin@mediatek.com/
But it seems not robust enough.

Then we refer to this io_start solution, the idea from Angelo:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c?h=next-20220408#n789


I'm not sure if there is another more suitable idea to fit in this
problem.
But I believe, if using different compatibles for each mmsys is
acceptable, then we can keep the original compatible method for
mediatek-drm and mmsys, and also make these works easier.

If you have any ideas to simplify it, please help us :-)
Thanks for your reviews again.

[PATCH v20 3/8] drm/mediatek: add DSC support for mediatek-drm

[jason-jh.lin]

DSC is designed for real-time systems with real-time compression,
transmission, decompression and display.
The DSC standard is a specification of the algorithms used for
compressing and decompressing image display streams, including
the specification of the syntax and semantics of the compressed
video bit stream.

[PATCH v20 3/8] drm/mediatek: add DSC support for mediatek-drm

[jason-jh.lin]

DSC is designed for real-time systems with real-time compression,
transmission, decompression and display.
The DSC standard is a specification of the algorithms used for
compressing and decompressing image display streams, including
the specification of the syntax and semantics of the compressed
video bit stream.

[PATCH v20 6/8] soc: mediatek: add DDP_DOMPONENT_DITHER0 enum for mt8195 vdosys0

[jason-jh.lin]

The mmsys routing table of mt8195 vdosys0 has 2 DITHER components,
so mmsys need to add DDP_COMPONENT_DITHER1 and change all usages of
DITHER enum form DDP_COMPONENT_DITHER to DDP_COMPONENT_DITHER0.

But its header need to keep DDP_COMPONENT_DITHER enum
until drm/mediatek also changed it.

[PATCH v20 7/8] drm/mediatek: add suffix 0 to DDP_COMPONENT_DITHER for mt8195 vdosys0

[jason-jh.lin]

Because mt8195 vdosys0 has 2 DITHER components,
so the suffix 0 need to be added to DDP_COMPONENT_DITHER.

Then DITHER enum will become:
DDP_COMPONENT_DITHER0 and DDP_COMPONENT_DITHER1.

Chun-Kuang, I think it would make sense to take that through your tree as it 
depends on the previous patches.

I provide you a stable tag so that you can take it:
v5.18-next-vdso0-stable-tag

After I take this tag, I find one checkpatch warning:

WARNING: DT compatible string "mediatek,mt8195-mmsys" appears
un-documented -- check ./Documentation/devicetree/bindings/
#670: FILE: drivers/soc/mediatek/mtk-mmsys.c:390:
+               .compatible = "mediatek,mt8195-mmsys",

I think this tag lost one binding patch, it's better that this tag has
no this warning.

Sorry for the late reply I was sick.
The warning is, because the stable branch misses commit:
https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/commit/?h=v5.18-next/soc&id=81c5a41d10b968ea89d5f44fe1e5c2fc70289209

So it's not a real issue and will go away once our branches land in upstream.
Is it OK for you to ignore the issue?

Matthias

Sorry for the late reply I was sick.
The warning is, because the stable branch misses commit:
https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/commit/?h=v5.18-next/soc&id=81c5a41d10b968ea89d5f44fe1e5c2fc70289209

So it's not a real issue and will go away once our branches land in upstream.
Is it OK for you to ignore the issue?

It's OK for me, but the patch would go through different maintainer's
tree and I'm not sure it's OK for all of them. So I would wait for the
necessary patch land in upstream.

Re: [PATCH v20 0/8] Add Mediatek Soc DRM (vdosys0) support for mt8195

Hello Jason,

this series does not apply cleanly anymore on next-20220525, can you please
rebase and resend?

I hope that with a bit of coordination, we can get the entire display stack
finally upstreamed in v5.19... it's been quite a while... :-)

Cheers,
Angelo

Hello Jason,

this series does not apply cleanly anymore on next-20220525, can you please
rebase and resend?

I hope that with a bit of coordination, we can get the entire display stack
finally upstreamed in v5.19... it's been quite a while... :-)

Cheers,
Angelo
