tmlind: do you have any idea where to look for usleep_range() latency? I enabled ftrace function tracer but don't know how to analyze the results. BTW, it turned out we have the same issue on d4.
<tmlind>
freemangordon: ok, sorry not sure what might be broken at this point, will try to find my old notes on timer tests so maybe it can be narrowed down a bit
<tmlind>
seems short usleep_range() can take much longer than specified?
<freemangordon>
on average 400us
xmn has joined #maemo-leste
<freemangordon>
according to cyclictest
<freemangordon>
setting pm_qos_resume_latency_us makes no difference
<freemangordon>
increasing the priority however does
<freemangordon>
cyclictest -p 80 -m -i 100 results in 40us average
<freemangordon>
on d4
<freemangordon>
so maybe it is just a matter of scheduler priority, dunno

sounds like if priority affects it
<freemangordon>
mhm
<freemangordon>
but calling cpu_latency_qos_add_request() does nothing
<freemangordon>
OTOH, returning -EAGAIN from pwm_ir_suspend seems to make things better
<freemangordon>
so I am starting to think this is idle related, like CPU enter too deep idle state which needs lots of time to resume from

seems like reloading the d4 modem modules including phy-mapphone-mdm6600 every two weeks works around the modem weirdness, uptime again close to 23 days, this still the old v6.1 based kernel
<tmlind>
so maybe some modem firmware bug triggering some bug on linux

tmlind: nice digging
<Wizzup>
I wonder if this is also the case for turning it in offline mode or not

not sure what goes wrong, but i've had uptimes past two weeks by doing modem reload
<Wizzup>
ok
<Wizzup>
I do sometimes put my d4 into offline mode, which is why I asked
<Wizzup>
this doesn't unload the modules but I suppose it puts the modem in some other mode at least
<tmlind>
ah ok yeah no idea if offline mode is enough to avoid the issue
<tmlind>
i've noticed that the qmi data connection at some point can run out of connection id's so maybe that's related
<Wizzup>
hmm

i made it a separate commit in case it turns out unnecessary. looks to me like the decision to use dns[0] or dns[1] was meant to be made depending on availability or non-availability of dns[1], not dns[0]

<Wizzup>
good eye!

I'll get this going now.

Wizzup: sicelo: i finally successfully built a pcsx-rearmed package for Leste and neon optimized :) it works full speed + sound on N900 :D

should work on D4 with far better rendering with few modifs
<Wizzup>
great
<Wizzup>
what modifs?
<arno11>
for example the key mapping is maybe different
<arno11>
(hardcoded)
<arno11>
and maybe we should use different cflags for optimization
<arno11>
and for better rendering it is just a question of settings
<arno11>
(opengl rendering with scalex2 + filters for example)
<arno11>
but when you see how it runs on n900, could be awesome on D4 really
<arno11>
pcsx burns 'only' 300mA with pulseaudio on n900
<Wizzup>
right, ideally we'd have one build for all devices, but maybe some config files
<Wizzup>
in any case, cool
<Wizzup>
!
<arno11>
yes cool :) i think i just need to check few things about d4 and update config file
<arno11>
anyway maybe it works well with n900 optimization
<arno11>
i'll update my repo and then maybe you can try on your D4 ?
<Wizzup>
sounds good, I'll need some rom to try it on, I haven't done much with the ps recently :D
<arno11>
ok, and btw the HLE bios integrated in the emu works well
<arno11>
so you just need a .bin game ;)

arno11: assuming you can use fremantle on n900, you might want to benchmark pcsx-rearmed there and compare
<arno11>
yes :) with no real benchmark, it already seems similar in term of perf
<arno11>
definitely better in term of power cons.
<arno11>
and really don't know why

on leste cpu usage is around 50-60% @25 fps in Gran Turismo for example

surprisingly it works better on leste @ the same freq (850MHz): similar cpu usage at around 25 fps but smoother on leste with better sound
