From: Andy Yan <[email protected]>
This patch sets aims at enable the VOP2 support on rk3588.
Main feature of VOP2 on rk3588:
Four video ports:
VP0 Max 4096x2160
VP1 Max 4096x2160
VP2 Max 4096x2160
VP3 Max 2048x1080
4 4K Cluster windows with AFBC/line RGB and AFBC-only YUV support
4 4K Esmart windows with line RGB/YUV support
The current version support all the 8 windows with all the suppported
plane format.
And we don't have a upstreamed encoder/connector(HDMI/DP) for rk3588
yet, Cristian from collabora is working on adding upstream support for
HDMI on rk3588.
My current test is runing with a HDMI driver pick from downstream bsp kernel.
A branch based on linux-6.7 rc2 containing all the series and
HDMI driver(not compatible with mainline rk3568 hdmi) picked from downstream bsp kernel
is available [0].
[0]https://github.com/andyshrk/linux/tree/rk3588-vop2-upstream-linux-6.7-rc2-2023-11-22
Changes in v2:
- fix errors when running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
- split dt-bindings form vop driver patch
- add rk3588_ prefix for functions which are rk3588 only
- make some calculation as fixed value and keep calculation formula as
comment
- check return value for some cru calculation functions.
- check return value for syscon_regmap_lookup_by_phandle
- add NV20/NV30 for esmart plane

2.34.1
From: Andy Yan <[email protected]>
This reverts commit b63a553e8f5aa6574eeb535a551817a93c426d8c.
regcache_sync will try to reload the configuration in regcache to
hardware, but the registers of 4 Cluster windows and Esmart1/2/3 on
the upcoming rk3588 can not be set successfully before internal PD
power on.
Also it's better to keep the hardware register as it is before we really
enable it.
So let's revert this version, and keep the first version:
commit afa965a45e01 ("drm/rockchip: vop2: fix suspend/resume")

At first we thought the half_block_en bit in AFBCD_CTRL register
only work in afbc mode. But the fact is that it control the line
buffer in all mode(afbc/tile/line), so we need configure it in
all case.

The output interface related definition can shared between
vop and vop2, move them to rockchip_drm_drv.h can avoid duplicated
definition.

From: Andy Yan <[email protected]>
The vop2 on rk3588 is similar to which on rk356x
but with 4 video ports and need to reference
more grf modules.

You relax requirements for all existing variants here which is not
explained in commit msg. I assume this was not intentional, so you need
to re-constrain them in allOf:if:then.
See for example:
https://elixir.bootlin.com/linux/v5.19-rc6/source/Documentation/devicetree/bindings/clock/samsung,exynos7-clock.yaml#L57
for some ideas.

Drop last sentence, instead add it to required in allOf:if:then.
Is this valid for other variants? If not, should be disallowed in
allOf:if:then: for them.

For all these three: what is "misc control"? Way too vague. Everything
is a misc and everything can be control. You must be here specific and
much more descriptive.

Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v6.4-rc1/source/Documentation/process/submitting-patches.rst#L597
Subject:

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.
https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577
Best regards,
Krzysztof

If I'm not mistaken this prints a register space of 0x110 bytes.
Shouldn't it be 0x100 bytes instead?
Also, are all these register spaces really have the same size? Does it
make sense to add the size to struct vop2_regs_dump?

Can you create a statically initialized array of struct vop2_regs_dump
and iterate over it?
You would need an additional present_in_soc_xy flag in struct
vop2_regs_dump, but other than that I don't see a problem and the result
might look better.
For the windows it might also be an option to iterate over
vop2->data->win instead. This array already contains the register base
addresses and window names.

Not sure if we really need an additional debugfs entry to print only the
active entities, but if we do then we could avoid a bit of code
duplication by adding creating a common register dump function called
from vop2_regs_show() and vop2_active_regs_show() which takes an
additional ignore_disabled argument.

Hi Andy,
Looks good overall, two small things inside.

Not that it matters in practice here, but you should add braces around
the x argument in the macros usage, i.e. ((x) == ROCKCHIP_VOP2_EP_RGB0)

you should clear the bits of a mask before setting them again. The same
goes for several other bits modified in this switch/case.

This struct already contains a bool type variable. Please add this one
next to it to keep the struct size smaller.

This looks common to the rk3568 variant, right, so I guess this should
have a

I don't fully understand that code:
(1) the write mask is also present on the rk3568, so should this change
be a separate patch with a fixes tag?
(2) RK3568_REG_CFG_DONE__GLB_CFG_DONE_EN does not contain the part for
the write-mask
#define RK3568_REG_CFG_DONE__GLB_CFG_DONE_EN BIT(15)
why is this working then?

I think this at least warrants a comment, what is happening here. Also,
can you already see how future vop2-users are behaving - aka are all new
socs in the "else" part of the conditional, or would a switch-case better
represent future socs?

hmm, shouldn't the check for the validity of a mode happen before
atomic_enable is run? So this shouldn't error out in the middle of the

I'm not sure if we need a Fixes tag here, in fact this issue never happens on
rk3566/8 , because the cluster windows of rk356x only support afbc format,
they don't have a chance to switch between afbc and linear mode.
Of course, the lack support of linear mode of rk356x cluster windows is a thoughtless
of IC design, if it really support both afbc and linear format, we indeed need this fix.
The situation is the same as patch 03/12.
So I hope follow your advice, if it need a Fixes tag here.

ah ok, thanks for the explanation. Then I guess we don't need a fixes tag
when the rk3568 is not affected by this.
Same for the other patch. If you're re-sending you could add this information
to the commit message though. (existing support for rk3568 only supports
afbc cluster windows and is therefore not affected)
Thanks

The write mask of VP config done on rk356x is missing, that means
you can write the corresponding mask bit, but it has no effect.
I once considered making it a separate patch, I can split it as a separate patch if
you like.

Actually this bit has no write-mask bit. ????

On rk356x, this bit is auto gating enable, but this function is not work well so
we need to disable this function.
On rk3588, and the following new soc(rk3528/rk3576), this bit is gating disable,
we should write 1 to disable gating when enable a cluster window.
Maybe i add some comments in next version ?

when doing that separate patch mentioned above, could you also add a
comment to the code stating that RK3568_REG_CFG_DONE__GLB_CFG_DONE_EN
doesn't have a write mask bit please?
Because the TRM is not clear and ideally I'd not forget this fact for
the future :-) .

Yep that comment would be helpful. And with your explanation the code
itself can stay as it is :-)

Actually it is a check like the check of clk_prepares_enable at the beginning,
maybe one place can do this is at crtc_atomic_check ? But we really don't need to
do the calculate and enable the related interface at every frame commit.
with a grep i can find many platforms do this kind of check in crtc_atomic_enable(ade/meson/vc4/omap/malidp/tidss_crtc_atomic_enable, etc...)
so maybe just let it as it is now?

I don't think so. Just follow the original code write it here.
Anyway, I will just write once in next version.
And would you please check my response about debugfs patch[0] when it is convenient for you?
I want to know what you think, and prepare the next version.
