15:58 <dougg3> hi! I've been slowly getting an old PXA168-based device up and running with modern kernels. It has a GC300 in it. I honestly don't know how to even use it, but wanted to mention I ran into "imprecise external abort" when loading the etnaviv kernel module

15:59 <dougg3> i was able to get past it by commenting out etnaviv_gpu_enable_mlcg(), which then led to another one, which I got past by commenting out etnaviv_gpu_setup_pulse_eater(). but I don't think it's actually working, so I'm guessing I wasn't supposed to do that :)

16:00 <dougg3> now it loads, but I get "etnaviv-gpu c0400000.gpu: GPU not yet idle, mask: 0x000000fe". etnaviv_2d_test from libdrm says "etna_gpu_new: No such device or address" so I'm guessing it's not actually working. but the kernel definitely recognizes it as a GC300, so progress!

16:00 <dougg3> etnaviv-gpu c0400000.gpu: model: GC300, revision: 1051

16:03 <austriancoder> dougg3: it might help to have a look what the vivante driver would do - maybe here: https://source.codeaurora.org/external/imx/linux-imx and a tag like: imx_5.4.3_2.0.0

16:04 <austriancoder> dougg3: I have not the time to look into it by my own right now - sorry

16:06 <dougg3> thanks austriancoder!
