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)?

I'd rather keep it simple as rockchip_vpu_hw.c and just throw in there

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 ;-)

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.

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!

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

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.

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

2021-01-07 Thread 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.
