20:48 <Capteyn> Hi! Has anyone seen etnaviv working on the i.MX8 QuadMax (gc7000 rev 6009)? I'm having some issues...

20:50 <austriancoder> Capteyn: have no such board at my hands.. should change soonish.

20:53 <austriancoder> Capteyn: what issues you are seeing?

20:55 <Capteyn> austriancoder I've got the driver up and running, attached to the GPUs, but I'm getting a similar error to that what was seen (and maybe fixed?) on the i.MX8MM, an MMU error / recover hung GPU / AIX bus fault. However, the fix for the other revs doesn't seem to apply to this one.

20:55 <Capteyn> etnaviv-gpu 53100000.gpu: MMU fault status 0x00000000

20:55 <Capteyn> etnaviv-gpu 53100000.gpu: recover hung GPU!

20:56 <Capteyn> etnaviv-gpu 53100000.gpu: AXI bus error

20:56 <Capteyn> Those errors, repeated.

21:00 <austriancoder> Capteyn: okay... you could check what the galcore kernel driver does. have not yet looked too deeply into the rev6009.

21:00 <Capteyn> I'm curious if anyone has seen it work on the QuadMax...internet searches have yielded no good results so far.

21:01 <austriancoder> Capteyn: I am not aware of anybody ..

21:02 <Capteyn> austriancoder: I haven't looked at galcore much, I thought it was just a shell to point out at the closed-source Vivante driver. But, I will take a look.

21:05 <austriancoder> Capteyn: https://github.com/nxp-imx/linux-imx/tree/lf-6.1.y/drivers/mxc/gpu-viv

21:05 <austriancoder> Capteyn: if you have any kernel patches etc. feel free to send them ..

21:08 <Capteyn> austriancoder: Will definitely share patches if I find something that works! Thanks for the link -- I've been seeing those patches for other imx8 CPUs with 4GB+, but it doesn't seem to work/change anything with the QuadMax...this one I have not specifically seen, however.

21:21 <Capteyn> I'm currently bound to the linux-fslc-imx kernel, v5.15...that could be an issue.

21:44 <Capteyn> austriancoder: I just tried that patch from the link you sent, didn't help on my kernel. I'll keep looking.
