Orange Pi RV2

Is this specific patch that reverts the busy looping thread?

@maxsub yes and no. That 900*.patch never was meant to be in the Armbian repo, I wounder how this made it in the Armbian repo. Some black git magic...

 

Patch experimentally rolls back an upstream change (...that removes the kthread under discussion and by this prevents the main CPU from communicating to the remote CPU). Upstream (the Fedora folks that emitted the SpacemiT code drops) has removed the kthread to prevent high CPU load b/c they use RV2 for their RISCV compile farm or so. The 900*.patch was an experiment by me to understand the impact on HDMI audio / ADMA).

 

Long blabla. This proposed and committed change solves the issue for my pull RQ on the topic: https://github.com/armbian/build/pull/9299/changes/613737fab5aadc2d0a288a10a98aa0a433db4e76

I patched that, am rebuilding and will post the R2S temps after that patch.

The patch brought the idle load average drastically down on the R2S from 2.0 to 0.18.

However the temp remains at 57-58 deg C.
