adding projects linux-mako & linux-flo, is it possible to change to the
interactive governor by default  (instead of OnDemand)

also, not just for mako/flo but this is a question that should be
asked/answered for all devices (arale, krillin,... as well)

[Alberto Aguirre]

Looking at callgrind output on the desktop, there are no obvious mir
hotspots we could single out and optimize. It's similar to the output of
perf, in that quite a bit time is just spent in the GL + dri driver
code.

One more point, using the interactive governor (which we should be
defaulting to anyway) the N4 cpu usage reported by top is around 23%.

[Bug 1513450] Re: ActivityIndicators cause very high cpu usage for unity8/mir even when visible: false

[Alberto Aguirre]

Also worth noting that the 40% figure is with the default "ondemand"
governor, which changes cpu clock "ondemand" and can potentially also
change gpu clocks.

Using the "performance" governor (which fixes the cpu clock and
potentially the gpu clock) the figure is closer to 10% cpu load on an
N7.

On a vegetahd, with the default cpu governor, the server cpu load is
around 20%. With the performance governor, the cpu load is around 11%.

@Alberto - so last week we were pretty well focused on n4 & n7when i
logged this bug. Which are both code aurora afiak, so I'm wondering if
we're chasing a gpu specific issues. maybe it's worth a quick check on
mx4 or bq devices for comparison.

[Bug 1513450] Re: ActivityIndicators cause very high cpu usage for unity8/mir even when visible: false

[Alberto Aguirre]

I'm trying to get perf to return a more complete picture, but from the
attached flame graph (one mir_demo_server, one
mir_demo_client_egltriangle in Nexus 4):

Of the time spent in mir (29%) roughly 50-60% of that is spent in the
driver/kernel code (related to gpu/display)
