I need to check if the current rockchip iommu driver will work for this decoder. I remember that the iommu code for AV1 was a bit different, not sure about this rkvdec. > I would also consider adding the rkvdec1 node(s), if I am understanding > correctly they can both be used in a cluster or completely independent. They can be used independently, yes. I'll add rkvdec1 for rk3588 devices (rk3588s only has 1 core) Regards, Detlev. > Also on RK3582/RK3583 one (or both) of the decoder cores may be marked > as bad, yet the remaining one can still be used independently.

He had a lot of fruitful discussions for the VEPU121/VPU121 support he is working on. Baseline being, while we want the hw to be described correctly wrt the multiple instances, we don't generally want to expose them individually to userspace, because that would then require userspace to do all the scheduling.

I'll add rkvdec1 for rk3588 devices > (rk3588s only has 1 core) I do not think that is true, the rk3588s variant should also include two decoder and two encoder cores. However, the rk3582/rk3583 variants (rk3588s with one or more bad cores) may have 0-2 cores working for the decoder and/or encoder. E.g on my rk3582 boards I have following different ip-state in otp: - 1 bad cpu core (ip-state: 10 00 00) - 1 bad decoder core (ip-state: 00 80 00) - 1 bad encoder core (ip-state: 00 00 04) The general idea is that bootloader will disable or delete the offending nodes in the device tree to correctly describe the HW for the OS.

Agreed, the decoder is a SoC feature. As such, it should be enabled on the SoC level, instead of having it enabled on the board level.

Yes, basically, it makes the driver check for all nodes with the same compatible and list the instances in the same device instance. If multicore is not supported, the other instances can simple be ignored. See here: https://lore.kernel.org/linux-kernel/20240613135034.31684-4-sebastian.reichel@collabora.com/ > Baseline being, while we want the hw to be described correctly wrt the > multiple instances, we don't generally want to expose them individually > to userspace, because that would then require userspace to do all the > scheduling. Yes, so Sebastien's patch will allow the device tree to have the 2 cores but only one visible by the userspace (even when multicore decoding is not supported)

I see, so I will add both cores, enabled, in rk3588s.dtsi and let the bootloader disable the ones that are bad.
