adjtm_mntmn, now that you mentioned coral, there is an i.mx8m in preproduction with NPU (neural processing unit)18:37
adjtm_I don't know if it's pin compatible18:37
adjtm_https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-8-processors/i-mx-8m-plus-arm-cortex-a53-machine-learning-vision-multimedia-and-industrial-iot:IMX8MPLUS18:39
mntmnyeah i know, imx8m+18:40
mntmnadjtm_: unfortunately there is zero technical information on it yet18:42
adjtm_the most important is how open is the NPU18:42
mntmnmhm19:03
cphealyFrom what I've seen in the open NXP repo, it appears the NPU is also Verisilicon IP.  Likely similar R/E work would need to be undertaken to get a blob free solution for it.19:08

adjtm_cphealy, how that compares with other NPU like the one used in rk3399pro or coral?21:51
cphealyadjtm_: I don't know.  I just see that the NXP kernel code is using the same driver stack for it and the GPU.21:57
cphealyI assume this means at least some of the architecture is shared.  (MMU, AXI gasket, etc, etc.)21:57
cphealySimilar to how the i.MX6 has 2D GPU, 3D GPU, and VG GPU with shared parts.21:58

terprii have a list of random technical/design questions (ranging from "y no usbc" to ideas for cramming in interior usb devices), is it ok to dump a list of 5-10 questions here or is there a better forum for that?22:50
mntmnterpri: good forum here22:51
terpricool. got to go run errands but i'll send a question-dump in a bit22:52

adjtm_ndufresne, I don't know about rk3399pro, and coral is google IP afaik23:56
adjtm_it would be to have a libre software friendly NPU at least for inference23:56
adjtm_it would be nice23:57
