This describes in broad lines the how an AMD GPU is organized, in
terms of hardware blocks.

This series starts by splitting the amdgpu/index file to make some
room for additional contents.
The rest is basically bringing Alex' descriptions of the hardware and
driver internals into the doc.

This series starts by splitting the amdgpu/index file to make some
room for additional contents, but I'm not really happy with the
result, we can certainly do better.
The rest is basically bringing Alex' descriptions of the hardware and
driver internals into the doc.

Thanks for the details Alex!
Here is an attempt to formalize the decomposition of a
(mostly Renoir) APU, using plantuml. That's highly preliminary,
focusing on blocks/sub-blocks/firmware, based on my current
partial (and surely incorrect at places) understanding.
I focused on getting contents qui

Hello,
Context: trying to understand what happens with my Renoir passed through
to a Xen domu [0] (starting with the "VCN disabled" because I don't need it
now (so let's postpone the problem with its _fini) and with "PSP disabled"
because the alternative issue seems easier to solve -- so ip_block_
