[PATCH 3/5] dt-bindings: media: rockchip-vpu: Add PX30 compatible

[Paul Kocialkowski]

The Rockchip PX30 SoC has a Hantro VPU that features a decoder (VDPU2)
and an encoder (VEPU2). It is similar to the RK3399's VPU but takes an
extra clock (SCLK).

[PATCH 4/5] arm64: dts: rockchip: Add VPU support for the PX30

[Paul Kocialkowski]

The PX30 has a VPU (both decoder and encoder) with a dedicated IOMMU.
Describe these two entities in device-tree.

[PATCH 5/5] media: hantro: Add support for the Rockchip PX30

[Paul Kocialkowski]

The PX30 SoC includes both the VDPU2 and VEPU2 blocks which are similar
to the RK3399 (Hantro G1/H1 with shuffled registers).

Besides taking an extra clock, it also shares an interrupt with the IOMMU
so it's necessary to request the interrupt shared.

Looks like this trailing 0 shouldn't be here. Will fix in v2.

Looks like this trailing 0 shouldn't be here. Will fix in v2.

You could make this:

    clock-names:
      minItems: 2
      items:
        - const: aclk
        - const: hclk
        - const: sclk

And then:

allOf:
  - if:
      properties:
        compatible:
          contains:
            const: rockchip,px30-vpu
    then:
      properties:
        clock-names:
          minItems: 3

to make sure each variant has the correct clocks set.

Re: [PATCH 5/5] media: hantro: Add support for the Rockchip PX30

[Ezequiel Garcia]

Hi Paul,

Happy to see this patch. It was on my TODO list,
but I hadn't had time to bringup my rk3326 device.

A few comments.

Could you clarify on the commit description which iommu device interrupt
line is being shared?

Maybe this irq flag should be part of vpu->variant? It sounds like an IP block
integration specific thing.

Also, you will need a px30-specific interrupt handler now,
since the rk3399 one is not shared-friendly.

Perhaps it's time to rename this to rockchip_vpu_hw.c,
and merge rk3288 and rk3399? It's a nitpick, though.

Hi Paul,

Happy to see this patch. It was on my TODO list,
but I hadn't had time to bringup my rk3326 device.

A few comments.

Could you clarify on the commit description which iommu device interrupt
line is being shared?

Maybe this irq flag should be part of vpu->variant? It sounds like an IP block
integration specific thing.

Also, you will need a px30-specific interrupt handler now,
since the rk3399 one is not shared-friendly.

Sure! It's IRQ 79 of the GIC that's shared with vopl_mmu.
It's not very obvious in the dt commit.

Ah right, I agree that it would be justified. But it would also be simple to
just fix the irq handlers and assume this can generally be the case, because it
feels like a bit of a detail to justify a flag.

Do you think this could be a safe/workable assumption?

Yeah I realize I haven't been very careful there and didn't really check that
the IOMMU driver is really safe to handle shared interrupts either. I'll take
a look a that when crafting v2.

Haha, I was thinking the exact same thing but wasn't sure it would be welcome!

I was thinking of rockchip_vpu2_hw.c or rockchip_vdpu2_hw.c since that's
apparently how it's called in Rockchip terminology: VDPU2 and VEPU2 for the
Hantro G1 and H1 with the shuffled register layout. The rk3288 stuff is
probably VDPU1/VEPU1 and we might want to rename it accordingly as well.

Cheers and thanks for the review!

Paul

Ah right, I agree that it would be justified. But it would also be simple to
just fix the irq handlers and assume this can generally be the case, because it
feels like a bit of a detail to justify a flag.

Do you think this could be a safe/workable assumption?

Yeah I realize I haven't been very careful there and didn't really check that
the IOMMU driver is really safe to handle shared interrupts either. I'll take
a look a that when crafting v2.

Haha, I was thinking the exact same thing but wasn't sure it would be welcome!

I was thinking of rockchip_vpu2_hw.c or rockchip_vdpu2_hw.c since that's
apparently how it's called in Rockchip terminology: VDPU2 and VEPU2 for the
Hantro G1 and H1 with the shuffled register layout. The rk3288 stuff is
probably VDPU1/VEPU1 and we might want to rename it accordingly as well.

Cheers and thanks for the review!

Same here, I just had an occasion to use it again these days so I jumped

Sure! It's IRQ 79 of the GIC that's shared with vopl_mmu.
It's not very obvious in the dt commit.

Having looked through the docs again, I think that the vopl_mmu using
irq 79 is just a mistake:

(1) in general vop and vop-mmu use the same irq (78 in that case)
(2) Rockchip does seem to have fixed that in their 4.19 tree as well:
https://github.com/rockchip-linux/kernel/blob/develop-4.19/arch/arm64/boot/dts/rockchip/px30.dtsi#L1598

So to me it looks like this doesn't need to be shared and instead
"simply" the px30 dtsi fixed ;-)

Having looked through the docs again, I think that the vopl_mmu using
irq 79 is just a mistake:

(1) in general vop and vop-mmu use the same irq (78 in that case)
(2) Rockchip does seem to have fixed that in their 4.19 tree as well:
https://github.com/rockchip-linux/kernel/blob/develop-4.19/arch/arm64/boot/dts/rockchip/px30.dtsi#L1598

So to me it looks like this doesn't need to be shared and instead
"simply" the px30 dtsi fixed ;-)

Do you also mean merging all the rk*_vpu_hw.c files into one or just covering
the general helpers (and not the platform-specific structures)?

Do you plan to resend this series?

Alex recently renamed [1] things so some tweaking will be needed,
but it shouldn't be complicated.

[1] https://lore.kernel.org/linux-media/20210614213215.99389-1-knaerzche@gmail.com/

It would be great to have support RK3326 and PX30 :)

Kindly,
Ezequiel
