While looking for other ARMv8 based platform, I found that the RK3368
platform has the same SCPI implementation as Amlogic.
They extended it with DDR, system and thermal commands.
Look at :
So the SCPI must have a framework to allow different protocol
versions, and must allow command extension. Grouping Rockchip and
Amlogic should be done, thus needing a generic name like vendor_scpi
or with a version.
Makes sense. I understand the need to reuse and I need a bit of time to
have a look at the code(both Amlogic one's you have pointed out and the
Rockchip one) in detail to see what's the best way to proceed. I will
have a look at this later this week and get back to you.
Sudeep, could you somehow find out which version of the protocol
AmLogic and Rockchip based their SCPI development ?
Yes I tried checking with Rockchip but didn't get a response. But my
guess is that it was some preliminary unpublished version of SCPI
And if one partner did that, probably everyone else did as well, but
this being the ARM universe, they all did it slightly differently. :(
We know from experience, that this happens all the time in the absence
of a clear standard, so this framework will need to be extended to be
