05:38 <freemangordon> tmlind: it uses wait queue behind the scenes, so the same question is still valid. I guess I'll just implement it like that

05:41 <tmlind> freemangordon: ok yeah, no idea about the latencies here

06:03 xmn has quit [Ping timeout: 246 seconds]

06:05 <freemangordon> tmlind: for some reason, on n900 usleep_range(728, 728) sleeps for 10955 us :)

06:05 <freemangordon> seems there is something wrong with hrtimers on omap3

06:06 Danct12 has quit [Quit: WeeChat 4.0.4]

06:08 <tmlind> hmm sounds like there's some issue somewhere

06:10 Danct12 has joined #maemo-leste

06:11 <freemangordon> or, when asked for 307us sleeps for 2166748ns. Unless I am doing something stupid when logging the time https://pastebin.com/tMuYC1Cy

06:11 Danct12 has quit [Client Quit]

06:12 <freemangordon> the result https://pastebin.com/wDaFYHGX

06:12 <freemangordon> no wonder IR TX does not work :)

06:13 <tmlind> maybe run timer tests like cyclictest to check which timers are broken

06:14 <freemangordon> tmlind: ktime_t is timestamp in nanoseconds, right?

06:14 <tmlind> cyclictest and others are in the rt-tests package

06:14 <freemangordon> in the repos?

06:14 <tmlind> might be

06:14 <freemangordon> lemme try to find

06:15 * tmlind bbl

06:20 <freemangordon> tmlind: no idea how to read the results:

06:31 <freemangordon> WARN: measured clock resolution approximately: 30517 nsec

06:48 Danct12 has joined #maemo-leste

07:16 <tmlind> freemangordon: the max value is way too long it seems

07:22 <tmlind> hmm well it's high but it's not with rt patches

07:42 Danct12 has joined #maemo-leste

07:50 <freemangordon> tmlind: well, average 446 us does not look good to me

07:50 <freemangordon> given that timer resolution is 30us

07:51 <tmlind> is this with the mainline v6.5 or something else?

07:51 <freemangordon> 6.1.48

07:52 <freemangordon> this https://github.com/maemo-leste/droid4-linux/tree/maemo-6.1.y

07:52 <tmlind> ok

07:53 <tmlind> well CONFIG_NO_HZ_IDLE=y is needed for pm, but also causes the clockevent to be often reprogrammed for the next timer so there's some extra overhead

07:54 <tmlind> sched_clock() is slow because there is no localtimer

14:26 <bencoh> Wizzup: I don't see any either at least

14:28 <bencoh> which reminds me ... does anyone see odd cases of missed calls / sphone not making the phone vibrate / interrupted vibration?

14:33 <Wizzup> no, but I have had repeated smses still some times

15:42 <bencoh> Wizzup: I've had repeated SMSes for a day (and counting)

15:43 <bencoh> (I switched yesterday to d4 as a main phone)

15:43 <bencoh> is there a workaround to that btw?

15:51 <Wizzup> I don't know why it happens, but I think it has something to do with setting the display on/off (by that I mean what mce writes to the modem to silence the signal strength notifications on display on/off)

15:51 <Wizzup> because I get the repeated smses the moment I turn on the display

15:52 <Wizzup> check @ main phone, I finally have some peace so I'm going to revive the sphone tp part

15:52 <Wizzup> then we will hopefully finally also have sip/xmpp calls

16:00 <bencoh> how does the cellular part work nowadays? sphone takes care of everything (ie ofono, pulseaudio routing, vibration, ...)?

16:02 <bencoh> I noticed that I often get SMSes (either repeating, or just regular SMSes that didn't show up thus far) whenever I call or get a call

16:02 <bencoh> 41

16:02 <bencoh> (woops)

16:52 <tmlind> Wizzup, uvos: dtmf should be trivial to implement, there's the dtmf shell script at https://github.com/tmlind/droid4-sms-tools

17:08 <Wizzup> thanks
