[PATCH v4 00/17] Add VOP2 support on rk3588

[PATCH v4 00/17] Add VOP2 support on rk3588

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

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(1080P/4KP60) is runing with a HDMI driver pick from
downstream bsp kernel.

A branch based on linux-6.7 rc4 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/commits/rk3588-vop2-upstream-linux-6.7-rc4-2023-12-07

Changes in v4:
- fix the POST_BUF_EMPTY irq when set mode
- use full stop at all the description's end.
- address Krzysztof's review about dt-binding in v3
- keep all VOP2_FEATURE_HAS_xxx macros increase in order.
- address Sascha's review about debugfs
- Add const for rockchip,rk3588-iommu compatible

Changes in v3:
- split from the vop2 driver patch
- put bool variable yuv_overlay next to other bool variable
- define macro for RK3568_OVL_CTRL__YUV_MODE
- just write RK3568_OVL_CTRL register once in function
  vop2_setup_layer_mixer
- constrain properties in allOf:if:then
- some description updates
- change the subject as Krzysztof suggested, and add his ACK
- add braces for x in macro vop2_output_if_is_yyy(x)
- clear the bits of a mask before setting it in rk3588_set_intf_mux
- add more comments.
- put regs dump info in vop2_data

Changes in v2:
- fix errors when running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
- split 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

[PATCH v4 01/17] drm/rockchip: move output interface related definition to rockchip_drm_drv.h

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

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

[PATCH v4 02/17] Revert "drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume"

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

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")

[PATCH v4 03/17] drm/rockchip: vop2: set half_block_en bit in all mode

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

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/linear), so we need configure it in
all case.

As the cluster windows of rk3568 only supports afbc format
so is therefore not affected.

[PATCH v4 04/17] drm/rockchip: vop2: clear afbc en and transform bit for cluster window at linear mode

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

The enable bit and transform offset of cluster windows should be
cleared when it work at linear mode, or we may have a iommu fault
issue on rk3588 which cluster windows switch between afbc and linear
mode.

As the cluster windows of rk3568 only supports afbc format
so is therefore not affected.

[PATCH v4 05/17] drm/rockchip: vop2: Add write mask for VP config done

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

The write mask bit is used to make sure when writing
config done bit for one VP will not overwrite the other.

Unfortunately, the write mask bit is missing on
rk3566/8, that means when we write to these bits,
it will not take any effect.

We need this to make the vop work properly after
rk3566/8 variants.

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.

- 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

[PATCH v4 13/17] drm/rockchip: vop2: rename VOP_FEATURE_OUTPUT_10BIT to VOP2_VP_FEATURE_OUTPUT_10BIT

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

VOP2 has multiple independent video ports with different
feature, so rename VOP_FEATURE_OUTPUT_10BIT to
VOP2_VP_FEATURE_OUTPUT_10BIT for more clearly meaning.

[PATCH v4 14/17] drm/rockchip: vop2: Add debugfs support

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

/sys/kernel/debug/dri/vop2/summary:  dump vop display state
/sys/kernel/debug/dri/vop2/regs: dump whole vop registers
/sys/kernel/debug/dri/vop2/active_regs: only dump the registers of
activated modules

Signed-off-by: Andy Yan <andy.yan@rock-chips.com>

---

Changes in v4:
- check NULL pointer at right place
- fix the index of fb->obj
- drop explicitly cast of void pointer
- make the register dump code as a common function.

Changes in v3:
- put regs dump info in vop2_data

In the next iteration, please split this out into a separate patch and send
it to the iommu+dt maintainers.

Supporting the iommus on rk3588 can be realized separately and the
patch needs to go through a separate tree anyway.


Thanks

Okay, I will split this patch out of this vop2 series, does this mean that
I also need to split out the iommu dt node as a separate patch from current
PATCH16 ?

no :-) .

The vop-iommu can stay together with the vop core node.
As adding the actual vop iommu is very much tied to the vop node.

For the iommu-compatible it was different. The compatible just declares
that the iommu acts similar to the one on rk3568, so is related to the iommu
driver itself and should go through the iommu tree.

So all is good here.

Heiko

resets and reset-names do not seem to be part of the binding, so
should probably be added there.

[PATCH v4 17/17] MAINTAINERS: Add myself as a reviewer for rockchip drm

[Andy Yan]

From: Andy Yan <andy.yan@rock-chips.com>

As I am familiar with all the details of vop2 display
architecture, I can help review and test all related
changes in this subsystem, so add my email here to make
sure I get CC'd on rockchip drm changes.
