xesPali: freemangordon: if i'm not wrong, kernel-power does not includes BFS and BFQ patches. I can remember the tests with an old bfs was pretty fast. Have you ever tried to test BFQ and CK patches into the kp53?01:04
*** Elleo has quit IRC01:05
Palixes: me not01:06
xesi'm using kernels patched in that way in a few very low perf laptop and they make a big difference01:18
keriobig difference for what01:20
xeskerio: system response during high load01:21
*** pigeon has joined #maemo01:23
xesoften those patches are applied adding also the uksm dedup patch.. but i still can't observe any positive effect from that01:28

MaxdamantusDocScrutinizer05: yes, but does mce also listen for the touch events from Xorg?06:34
MaxdamantusI was asking what program actually connect to the X server, asks it to send it all touchscreen events, then somehow cause vibration.06:35
MaxdamantusI don't think that's mce.06:36
*** svetlana_ has joined #maemo06:38
DocScrutinizer05kill -sigstop `pidof mce`06:39
DocScrutinizer05-->no more vibra feedback from touchscreen06:39
DocScrutinizer05kill -sigcont `pidof mce`06:39
DocScrutinizer05--> all cued vibra events come out06:40
DocScrutinizer05queued even06:40
DocScrutinizer05so the answer is: yes it's mce that finally causes the touchscreen vibra06:40
MaxdamantusOf course, because they go through mce.06:40
MaxdamantusI'm not asking that.06:41
MaxdamantusIf you stop/continue Xorg you'll probably get the same thing.e06:41
MaxdamantusSo Xorg == mce?06:41
DocScrutinizer05you're interested in more answers?06:41
DocScrutinizer05I guess not, like you always been06:42
* DocScrutinizer05 fixes his ignore list. wonders what happened to it06:42
Maxdamantusmce doesn't initiate the chain of events. Neither does twl*vibra06:47
MaxdamantusThey're both parts of the chain I'm probably not asking about.06:47
MaxdamantusIiirc, the events go through Xorg, and I'm asking where they go from there. I don't think it's directly to mce. I think another program sends messages to mce.06:47
Maxdamantusalso, input lag, messages will probably appear all at once.06:47

DocScrutinizer05lsof |egrep "mce|Xorg" |grep unix|sort -k607:04
MaxdamantusI think mce does that for screen locking.07:06
MaxdamantusI'll look into it in an hour or so.07:07

Maxdamantuslooks like it's not.07:47
*** Vajb has joined #maemo07:48
MaxdamantusOkay, got it.07:48
MaxdamantusIt's maemo-xinput-sounds07:48
MaxdamantusJust did a grep for PatternTouchscreen across a backup of the root filesystem.07:49
*** svetlana has joined #maemo07:49
* Maxdamantus wonders why they didn't just put it in mce.07:49
MaxdamantusDocScrutinizer05: am I still ignored btw?07:51
* Maxdamantus suspects that's a yes and doc will be searching through mce for eternity looking for the bit where it triggers a vibration in response to the touchscreen.07:55

freemangordonDocScrutinizer05: jonwil: any clue who and how uses "sleep_ind" gpio?09:54
DocScrutinizer05err, gpio? hmm09:55
DocScrutinizer05wait, is this in our out?09:55
freemangordonyep, 16209:55
DocScrutinizer05sleep_ind is an output from SoC to enable blinking kbd backlight09:57
freemangordonI know, my question is who uses it09:58
DocScrutinizer05related to a /sys/*/??? I always forget the name of09:58
freemangordonhowever, it is referenced in an .qwk script in getbootstate09:58
DocScrutinizer05in a what?09:58
DocScrutinizer05it's used in preinit(?) via `echo 0 >/sys/bla/foo/bar`09:59
DocScrutinizer05echo active > /sys/devices/platform/gpio-switch/sleep_ind/state10:01
DocScrutinizer05line 33110:02
DocScrutinizer05then a nifty >>   awk '/sleep_ind/{ if ($2 == 1) { VALUE="active"; } else { VALUE="inactive"; } print VALUE > "/sys/devices/platform/gpio-switch/sleep_ind/state"  }' < /etc/pmconfig  <<10:02
freemangordongetbootstate does similar stuff10:04
freemangordongot it10:04
* DocScrutinizer05 frowns at using awk in #1 preinit10:07
DocScrutinizer05I know it's per default just another shade of messybox, but hey..10:08
DocScrutinizer05feels sort of wrong10:09

bencohMaxdamantus, DocScrutinizer05: looks like I was referring to "tactile", which is only in extras10:44
bencohtouchscreen feedback / vibration10:46
DocScrutinizer05ohh [2016-01-12 Tue 11:14:12] <bencoh> Maxdamantus: regarding touchscreen vibrating feedback, there is a daemon in a separate package10:46
bencohbut I'm not sure it's what you're looking for since it's in extras-devel10:47
DocScrutinizer05I'm not really looking for anything :-)10:48
bencohyou or Maxdamantus :)10:48
DocScrutinizer05no idea, never heard of tactile10:48
DocScrutinizer05touchscreen vibra feedback is maemo core10:49
DocScrutinizer05maybe tactile is made to tweak that stuff10:49
*** sledges has joined #maemo10:49
*** sledges has joined #maemo10:49
DocScrutinizer05there been an idea a few years(=) ago to not only give vibra feedback for pen-down but also when pen hits borders of widgets like buttons or icons or whatever10:51
DocScrutinizer05a tad useless since you usually don't try to hit buttons with pen-down10:52
infobotDocScrutinizer05 meant: a tad useless since you usually don't try to hit buttons while pen-down10:52
DocScrutinizer05hmm >> tactile provides improved tactile feedback with different  patterns to improve the user experience on the N900.<<10:53
bencohxes: aren't bfs/bfq useful in case of high cpu load?10:54

xesi'm using a kernel with BFS/BFQ patches into a (slooow) Sony VGN-P11Z and it gives a nice kick to overall system usability14:56
xes^^ "Conclusion: The results indicate that CFS outperformed BFS with minimizing turnaround time but that BFS outperformed CFS for minimizing latency. This indicates that BFS is better for interactive tasks that block on I/O or user input and that CFS is better for batch processing that is CPU bound."14:57
