05:41 <tomeu> lynxeye: have made lots of progress on the NPU tflite delegate, but I'm stumbled by the GPU hanging every time I try to use the 8th NN core

05:42 <tomeu> the cmd stream and all buffers are bit identical

05:42 <tomeu> do you have any suggestions on how to debug this further?

06:36 <austriancoder> tomeu: maybe have a look at the registers that get written/read by the kernel driver

06:37 <tomeu> austriancoder: is there any tooling that would make this easier?

06:37 <tomeu> guess I should also decode all the cmdstream that the kernel generates

06:41 <austriancoder> tomeu: the galcore kernel driver has some kind of infra in place that needs to be enabled. Just have a look at e.g. gckOS_WriteRegisterEx(..) and the usage of gcmkHEADER_ARG(..)

06:42 <austriancoder> tomeu: yeah.. having a look at the cmdstreams the kernel generates might be also helpful. Maybe they are also using their debug infra for this.

06:44 <tomeu> I was thinking of some scripts in etna_viv to decode registers, cmdstream, etc

06:47 <austriancoder> for cmdstream there is something: dump_separate_cmdbuf.py

06:57 <tomeu> ok, thanks, will give that a try
