mpp_rkvenc fdf40000.rkvenc: no memory region mapped

[denghengli]

一、版本信息

平台：RK3568 kernel：5.10.198 libmpp：1.0.6 librga: rgaapi version 1.3.1[11] (RGA is compiling with meson base: $PRODUCT_BASE) RGA Deriver：RGA2 Device Driver: v2.1.0

二、mpp使用说明

1、4路摄像头rtsp取流-->mpp H265解码-->RGA分辨率转换--->mppH65编码+OSD字符叠加 2、每路摄像头rtsp取流 跟 mpp编解码都是独立的线程，两个线程直接通过的队列传递AVPacket

三、日志信息

1、kernel启动的时候mpp_rkvenc相关的打印信息，看着有一些失败的信息 [ 2.781678] mpp_rkvenc fdf40000.rkvenc: Adding to iommu group 5 [ 2.781888] mpp_rkvenc fdf40000.rkvenc: probing start [ 2.782322] mpp_rkvenc fdf40000.rkvenc: bin=0 [ 2.782344] mpp_rkvenc fdf40000.rkvenc: Failed to get leakage [ 2.782427] mpp_rkvenc fdf40000.rkvenc: pvtm = 87650, from nvmem [ 2.782437] mpp_rkvenc fdf40000.rkvenc: pvtm-volt-sel=1 [ 2.782605] mpp_rkvenc fdf40000.rkvenc: avs=0 [ 2.782718] mpp_rkvenc fdf40000.rkvenc: failed to find power_model node [ 2.782730] mpp_rkvenc fdf40000.rkvenc: failed to initialize power model [ 2.782738] mpp_rkvenc fdf40000.rkvenc: failed to get dynamic-coefficient [ 2.783315] mpp_rkvenc fdf40000.rkvenc: probing finish [ 2.783778] mpp_rkvdec2 fdf80200.rkvdec: Adding to iommu group 6 [ 2.783995] mpp_rkvdec2 fdf80200.rkvdec: rkvdec, probing start [ 2.784312] mpp_rkvdec2 fdf80200.rkvdec: shared_niu_a is not found!

四、问题疑问

1、kernel启动的时候的输出信息来看，是rkvdec驱动初始化有异常吗 2、运行一段时间后出现上面dmesg的问题，会是什么原因呢，应该怎么解决或避免？ 3、如果长时间这样运行会有什么问题吗，是否有影响 4、RGA也会报错，不知道是否了解会是什么原因呢

[HermanChen]

1. 内核启动 log 没什么问题，只是一些报警用 log
2. dmesg 看起来是 rga 先报错了 rga2 map dst memory failed，可能是 RGA 使用空间超 4G 空间了？或者是开了解码 FBC 输出，错误帧导致了 RGA 异常
3. 会有问题

[moo-the-cow]

I have that issue too: https://github.com/Joshua-Riek/ubuntu-rockchip/issues/1002 I posted quite some infos about it, it is still unresolved

this happens on the opi5 plus only. the other boards seem to be fine

[HermanChen]

It seems a kernel issue. Could you please provide the kernel mpp directory?

[HermanChen]

@FumasterLin reg 133 is a rcb address?

[moo-the-cow]

ok, I just upgraded the custom kernel of that repo from 1021 to 1025 it seems indeed a kernel issue, because it works now. Thank you for the hint!

[FumasterLin]

@FumasterLin reg 133 is a rcb address?

是的，有点奇怪

[denghengli]

ok, I just upgraded the custom kernel of that repo from 1021 to 1025 it seems indeed a kernel issue, because it works now. Thank you for the hint!

Are you saying that upgrading the kernel from 6.1.0-1021 to 6.1.0-1025 will solve the problem? Does that mean that this issue will also occur on 5.10.198?

[moo-the-cow]

I used a custom kernel and ubuntu version 24.04 https://github.com/Joshua-Riek/ubuntu-rockchip/

I was posting here because I had the same error message, but it turns out that the maintainer (see url above) messed up some kernel configs. I'm not sure if there is an issue with your kernel or something else.
