[PATCH RESEND 0/2] media: rockchip: rga: Add rk3568 support

[PATCH RESEND 0/2] media: rockchip: rga: Add rk3568 support

[Michael Tretter]

The RGA2 on the Rockchip rk3568 is the same core as the RGA2 on the Rockchip
rk3288.

This series adds the necessary device tree binding and node in the device tree
to enable the RGA2 on the Rockchip rk3568.

I tested the driver with the GStreamer v4l2convert element on a Rock3 Model A
board.

This is a RESEND including the linux-media list, as Heiko asked for an
Acked-by from someone from media.

[PATCH RESEND 1/2] media: dt-bindings: media: rockchip-rga: add rockchip,rk3568-rga

[Michael Tretter]

Add a new compatible for the rk3568 Rockchip SoC, which also features an
RGA, which is called RGA2 in the TRM Part2. It is the same core as used
on the rk3288, which documents the same RGA2.

Specify a new compatible for the rk3568 to be able to handle unknown
SoC-specific differences in the driver.

@media people: I'd guess this should go through the media-tree, while I
would pick the devicetree patch.

I can also apply this binding patch, but would need an Ack from the
media-side for it.

I am not really sure where to put such a TODO to make it visible for people
that are running into the issue and to make sure that it is removed once it is
fixed.

Maybe it would be better to add error handling to the rga_buf_map function to
fail if the address of the buffer that should be mapped has the upper 32 bit
set and print a warning. Furthermore, the driver would be able to skip the
buffer and prevent potential memory corruption caused by the erroneous
mapping.

Unfortunately, I don't have hardware that allows me to test this.

Hi Michael,

Seems we could use GFP_DMA32 flag to limit memory required by driver into

upper size range(actually using ZONE_DMA32 configured by device tree). Just

some driver modification needed. Maybe Nicolas could help testing? I would

like to fix this, but I don't have much free time these days.

Best regards,

I don't think the GFP_DMA32 flag works with DmaBuf import. The buffer may be
allocated by some other driver that is able to address more than 4G and
imported into the RGA driver. In this case, limiting the allocations is not
enough, but we would still need error handling in the map function for buffers
that cannot be addressed by the RGA.

I guess we need both, a limit for the allocation and error checking for the
map.

Maybe you are right.. I haven't digged into v4l2-m2m API, so I'm not 
sure about

it. Seems we need others' help.

Can this patch be merged via the media tree? I don't expect merging the
other one via a different tree being an issue either, so alternatively to
the 1st patch:

thanks for the Ack. To prevent conflicts with other additions to the
rk356x.dtsi file, I've picked now both patches for the rockchip tree.

I thought that was the reason that these patches weren't picked up before?

I have no insight into this problem, so I can't comment on the technical
aspects, but I had made a note for myself 'locally' about it.

Using the RGA2 with the driver in its current form on devices with more than 4
GB system memory may lead to memory corruption as buffer addresses are
silently truncated to 32 bits.

I'm not sure if that's actually a blocker for merging these patches.

That's because the driver is completely broken and is not using the DMA 
API anywhere near properly. The fact that it's been getting away with it 
so far can be mostly put down to good luck and nobody using 
CONFIG_DMA_API_DEBUG.

If anything, hopefully getting more SoC support merged might provide 
more motivation for someone to fix the existing code :)
