By that I mean that when I tried to play an HEVC video with mpv with
only core0 enabled, it would play fine, but trying to play videos in
another codec would result in power collapse fails. Likewise with core1,
but in other codecs.
I assume this is how cores are split - core0 does HEVC decoding and
core1 does the rest of codecs. This is confirmed by downstream code as
well (although the cores are flipped - core0 is the rest of codecs
("legacy") and core1 is HEVC):
