E.g. one value per file, backward compatibility etc...<br>

Apart from that I don't see any reason to not do it in sysfs.<br>

The main reasoning and use case for sysfs would be the SMI CLI,
since unfortunately there is no ioctl support in there.

We also expose the firmware versions via ioctl which is what
the UMDs uses. If you'd prefer it in sysfs, we could do that
too.<br>

<br>
Currently we retrieve firmware versions from
/sys/kernel/debug but this <br>
requires debugfs being enabled and superuser privilege.
Do you see a <br>
concern we add firmware versions to amdgpu sysfs at <br>
/sys/class/drm/cardX/device like vbios_version?<br>
<br>
Regards,<br>
Amber<br>
