Hi,

I gave this a go on the OnePlus 6, I noticed the driver is also meant to read
the stats for remote procs via smem, however this seems to fail for me - it
can't find any of the SMEM items even if I probe the driver manually after
ensuring remoteprocs have booted. Is this an unsupported feature on SDM845?
