Just a final observation.. having graphed the EU idle data from my bastardised intel_gpu_top application. Row0 EU0 never shows up as being used. Nor does it ever seem to appear in my intel_gpu_top profiles.
Can anyone else confirm this on a GM45 or other G4X generation chip? I'm wondering if it is: a) Real - and this EU is being ignored for some reason b) Real - and this EU is not accounted the same? c) A bug in the instdone.c library for intel_gpu_top (although I looked and couldn't see anything obviously wrong). d) A bug in the chip / docs / ... regarding the Row0 EU0 instdone flag Anyway... I was just looking greedily at it as a potential 1/8th of my GPU's cores which didn't seem to be pulling its weight. I _presume_ there is no such thing as a shipped laptop which has a dead and factory-disabled execution unit? Can I ask a really NOOB level question.. is the GM45 a Cantiga? If so.. shouldn't I be seeing flags for 10 EUs rather than 8? (According to the PRM? G45: Vol1a, P.28) Please dear goodness, someone tell me WHY Intel can't come up with a consistent and non-mind-bending way of naming their GPUs.. isn't the Generation number enough? Right 4AM, my sanity is gone.. sorry for all the noise ;) -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
