Bug ID: 111789 Summary: drm/etnaviv: command buffer outside valid memory window (on cubox i4), Linux 5.3 Product: DRI Version: unspecified Hardware: ARM OS: Linux (All) Status: NEW Severity: not set Priority: not set Component: DRM/other Assignee: dri-devel@lists.freedesktop.org Reporter: rechner@vlado-do.de

Created attachment 145475 --> https://bugs.freedesktop.org/attachment.cgi?id=145475&action=edit dmesg from kernel 5.3, loading firmware

I'm trying to get somewhat accelerated video output out of my CuBox i4 (imx6 cpu, GC2000 graphics), but I don't have any luck with kernels 5.0, 5.2, or 5.3.

I tried recent Armbian and Fedora (30 and 31 beta).

The etnaviv messages from dmesg are:

[ 18.891291] etnaviv etnaviv: bound 130000.gpu (ops gpu_ops [etnaviv]) [ 18.895022] etnaviv etnaviv: bound 134000.gpu (ops gpu_ops [etnaviv]) [ 18.898366] etnaviv etnaviv: bound 2204000.gpu (ops gpu_ops [etnaviv]) [ 18.898385] etnaviv-gpu 130000.gpu: model: GC2000, revision: 5108 [ 18.929873] etnaviv-gpu 130000.gpu: command buffer outside valid memory window [ 18.931182] etnaviv-gpu 134000.gpu: model: GC320, revision: 5007 [ 19.075240] etnaviv-gpu 134000.gpu: command buffer outside valid memory window [ 19.076522] etnaviv-gpu 2204000.gpu: model: GC355, revision: 1215 [ 19.076542] etnaviv-gpu 2204000.gpu: Ignoring GPU with VG and FE2.0 [ 19.083510] [drm] Initialized etnaviv 1.2.0 20151214 for etnaviv on minor 1

I'll attach the complete dmesg - or you can see it here: http://ix.io/1WAW

Google brought me to Russell King's similar problem from June: https://lists.freedesktop.org/archives/dri-devel/2019-June/224474.html

I don't know why the problem disappeared for him, though.

Initially I reported the problem at the armbian forum: https://forum.armbian.com/topic/11539-no-hdmi-with-linux-image-dev-cubox-ker...

I'm more of a user than a developer, especially when it comes to the Linux kernel. But I can test switches or patches.

Any help would be appreciated!
