npus



hey there, debian ai team! it was good to see lumin@ ITP
openvino today; i've been using that with Audacity for music
separation[2] the past few weeks.

anyway, i saw the message to -devel about NPUs[0]. i'm quite
interested in them, and did some compiler work with them at
google.

in general, you're going to find a minimum of firmware blobs,
DFSG-incompatibility-wise, and sometimes closed drivers entirely.
you'll also find that almost everyone has *some* degree of
openness, and the closure is generally due to political/legal
rather than technical reasons. you can assume a level of
annoyance roughly equivalent to working with FPGAs, though
there's work being done kernelside to improve things (kernel
never seemed to care much about FPGAs).

modern ones will be driven through the accel subsystem. older
ones are all over the map.

i don't have any hardware at the moment, but am happy to give
any advice i can.
