08:37 <freemangordon> heh, tracker-sparql is so smart... it caches up to 100 queries

08:37 <freemangordon> so, eventually, at some point memory usage will stop increasing :D

08:38 <freemangordon> unfortunately there is no way to disable the cache

08:38 <freemangordon> and 100 is hardcoded

08:38 <freemangordon> meh

09:08 <Wizzup> what is that cache for?

09:09 <freemangordon> sql queries

09:09 <freemangordon> umm...

09:09 <freemangordon> sql3 prepared statements

09:10 <freemangordon> it keeps a cache of LRU queries and the prepared statemets

09:10 <freemangordon> which is not that bad if you have 16G

09:11 <Wizzup> well, we can just decrease this number since we build it oursleves anyway

09:11 <freemangordon> but now, even after I have massaged it a bit, in the VM it uses ~230MB RES for ~ 1800 songs

09:12 <freemangordon> well, yeah, but I wanted to avoid that if possible

09:14 <Wizzup> wait so it also caches the results of the queries?

09:15 <freemangordon> no

09:15 <freemangordon> at least that's my understanding

09:16 <freemangordon> as it does sqlite3_reset() on cursor close

09:16 <freemangordon> but, it uses queries as hash table key

09:17 <freemangordon> I don;t know what is left after sqlite3_reset()

09:17 <freemangordon> https://www.sqlite.org/c3ref/reset.html

09:17 <freemangordon> but obviously a lot, so 20 of those take ~180 MB

09:47 <freemangordon> crowdfail, eh?

09:51 <Wizzup> hm?

09:51 <Wizzup> going to build new 6.6 now

09:53 <freemangordon> Wizzup: google "crowdstrike bsod"

09:53 <freemangordon> ;)

09:54 <freemangordon> I guess most of the windows machines are now there

09:54 <Wizzup> Ah

09:54 pagurus has quit [Remote host closed the connection]

09:55 <freemangordon> no, really, how is a single company allowed to have such a power to me is a mistery

09:55 <freemangordon> not to say that pushing production updates on friday is crazy

09:55 <Wizzup> there's many more companies with such power now :D

09:55 <freemangordon> yeah

09:56 <freemangordon> if it is not those guys then it will be some other "antivirus software" vendor

09:56 <freemangordon> the whole "windows security" is...

10:03 <Wizzup> of android, or ios :D

10:03 <Wizzup> or*

10:11 arno11 has joined #maemo-leste

10:12 <Wizzup> freemangordon: when this works I think we can move from experimental to devel, agree?

10:13 Wikiwide has joined #maemo-leste

10:17 <arno11> Wizzup: for d4, sounds good, but for n900 there is still the emmc swap issue making it buggy and unusable after few hours.

10:17 <arno11> the easiest way could be to use sd swapfile by default

10:17 <arno11> (temporary)

10:19 <Wizzup> yes, I have the pr open

10:19 <Wizzup> although I guess that's not for the other swap location

10:20 <Wizzup> we have the postinst rules for n900 in leste-config to update fstab, so we could do that

10:21 f_ has quit [Remote host closed the connection]

10:21 <arno11> yep but i suppose first boot will be longer if it has to create the swapfile or ?

10:26 Wikiwide has quit [Remote host closed the connection]

10:27 Wikiwide has joined #maemo-leste

10:27 <arno11> (for other swap location: i didn't notice any issue after 3.5 days with sd swap and no reboot)

10:34 <Wizzup> arno11: don't we have swap partition?

10:35 <Wizzup> maybe we don't

10:35 <arno11> we don't

10:36 <arno11> indeed, sounds good to have

10:36 Wikiwide has quit [Remote host closed the connection]

10:36 <Wizzup> well we can't just repartition :)

10:38 Wikiwide has joined #maemo-leste

10:38 Wikiwide has quit [Remote host closed the connection]

10:39 <arno11> otherwise we have to figure out what's going on with emmc

10:41 Wikiwide has joined #maemo-leste

10:41 <freemangordon> I think that's the proper thing to do

10:41 <arno11> yep and it still works perfectly with 6.1

10:42 <freemangordon> Wizzup: I think 6.6 is not ready for devel

10:42 <freemangordon> `because of reboot/shutdown issue

10:44 <arno11> what's the issue btw ?

10:48 <Wizzup> freemangordon: what is the issue?

10:49 <uvos__> Wizzup: the device hangs on shutdown/reboot

10:50 <uvos__> i did not see this problem early in the 6.6 cycle

10:50 <uvos__> not sure what changed

10:50 <uvos__> but it dose hang here now

10:50 <freemangordon> does here 19 of 20 times

10:50 <uvos__> for sure this dident happen at all when i initally rebased the kernel

10:51 <uvos__> back when cpufreq did not work

10:51 <uvos__> so either it came in with stable updates

10:51 <uvos__> or our additional patches since then

11:00 Wikiwide has joined #maemo-leste

11:02 <Wizzup> did someone connect serial and monitor kernel messages?

11:05 <freemangordon> I don't have serial, afaik

11:23 <Wizzup> oh

11:23 <Wizzup> if you have a usb ttyl serial like pl2303 or so it's very easy to make

11:23 <freemangordon> don;t have time now anyways

11:25 <Wizzup> in any case. new kernel is in repos

11:26 <Wizzup> I would argue it's ok for devel since it's devel, but I won't anymore then

11:29 <freemangordon> well, we know there is issue

11:29 <freemangordon> which is not minor though

11:29 <freemangordon> so, ...

11:29 Wikiwide has quit [Remote host closed the connection]

11:29 Wikiwide has joined #maemo-leste

11:31 <Wizzup> but audio works ;)

11:31 <Wizzup> I haven't seen the device ever hang with 6.6 I think, but I will check now with serial

11:31 <freemangordon> well, yeah, autio works :)

11:32 <freemangordon> *audio

11:32 <Wizzup> 'Will now restart.' and it restarts fine

11:32 <freemangordon> you are lucky

11:32 <freemangordon> lemme upgrade

11:32 <Wizzup> lucky every time eh :D

11:32 <freemangordon> mhm

11:32 <freemangordon> here it hangs every time

11:33 <freemangordon> well, reboots once in a while, but still

11:33 Wikiwide has quit [Remote host closed the connection]

11:33 <Wizzup> I have serial now, although I think due to how we disconnect the kernel messages from tty I might not see them on restart

11:33 Wikiwide has joined #maemo-leste

11:33 <Wizzup> how do you restart?

11:34 <Wizzup> or power off?

11:34 <freemangordon> sudo reboot

11:34 <freemangordon> and power-off reboots sometimes

11:34 <Wizzup> that has always ben the case for me (that power off sometimes reboots)

11:34 <freemangordon> but reboot hangs

11:34 <Wizzup> not for me, again

11:34 <Wizzup> (just rebooted)

11:35 <Wizzup> I might need to disable droid4-pm to get kernel messages upon shutdown if we think it is necessary

11:35 <Wizzup> but right now I can't reproduce

11:35 <freemangordon> upgrading the kernel, lets see after the upgrade

11:35 <Wizzup> this is on the droid 4 yeah?

11:35 <freemangordon> mhm

11:36 <Wizzup> trying switch off from ui now

11:36 <freemangordon> iphb was not rebuild upon upgrade

11:37 <Wizzup> switch off worked fine too

11:37 <Wizzup> freemangordon: got any console errors? I don't think I changed anything since that worked

11:37 <freemangordon> no

11:38 <Wizzup> ok, let me see if it is loaded for me then

11:38 <Wizzup> I didn't see any errors

11:41 <Wizzup> 'dpkg-reconfigure linux-image-omap' shows uninstall working ok, install also working ok

11:41 <Wizzup> but it wasn't loaded on my first boot somehow

11:41 <Wizzup> maybe the order in which headers are updated/installed vs when configure runs or something

11:41 <arno11> freemangordon: did you downgrade before upgrading ? (for iphb)

11:41 <freemangordon> no

11:42 <freemangordon> but it should work regardless

11:42 <arno11> (that's what i did to avoid errors)

11:42 <arno11> ok

11:42 <Wizzup> as stated, could be that headers aren't installed timely enough by dpkg

11:42 <Wizzup> there is no problem with kernel heads location or dkms

11:42 <Wizzup> (as in, rerunning works fine)

11:43 <freemangordon> no, it is not the headers

11:43 <freemangordon> it should fail if it does not find the headers

11:43 <freemangordon> it is something else

11:43 <freemangordon> so, how long does it take to reboot your device?

11:43 <Wizzup> what do you want timed excatly?

11:44 <Wizzup> from when I type 'reboot' to when I see motorola logo?

11:44 <freemangordon> as here it eventually rebooted, but I suspect it was WD

11:44 <freemangordon> yes

11:44 <freemangordon> poweroff hung it

11:44 <Wizzup> 28s

11:45 <freemangordon> like, I will have to reset it

11:45 <Wizzup> seems like I can't help since I can't reproduce

11:45 <freemangordon> :(

11:45 <Wizzup> (with my serial cable I mean)

11:45 <freemangordon> maybe bring me one

11:45 <Wizzup> I can bring the cable on Monday, or make a few

11:45 <Wizzup> ok

11:45 <freemangordon> yes, please

11:46 <freemangordon> new, old, does not matter

11:46 <Wizzup> https://www.olimex.com/Products/Components/Cables/USB-Serial-Cable/USB-SERIAL-M/

11:46 <freemangordon> do you have SIm card in that device?

11:46 <Wizzup> you need this + microusb cable

11:46 <Wizzup> yes

11:46 <Wizzup> I will order these then, since I also lack extra myself

11:46 <freemangordon> hmm, leme see, I have one from pinephone I guess

11:46 <Wizzup> yes but you'd have to destroy it

11:47 <Wizzup> rx / tx goes to usb d+ and d-, gnd to gnd

11:47 <freemangordon> is it usb-to-ttl what I need?

11:47 <Wizzup> yes, I always use the pl2303

11:48 <freemangordon> I have one here, lemme see what it is exactly

11:48 <Wizzup> olimex ships quickly so I think it'd best to just buy some and I'll bring my cable too next week

11:52 <freemangordon> Wizzup: this https://elimex.bg/product/74867-kit-k2118-konvertor-usb-kam-uart-ttl-cp2102-6pn

11:52 <Wizzup> if it is ttl level that is fine too, that's what matters

11:52 <freemangordon> how do I power that? I need external 5V?

11:53 <Wizzup> you don't connect power to the droid serial

11:53 <Wizzup> power for the module comes from usb

11:53 <freemangordon> ok

11:53 <freemangordon> where is droid4 serial?

11:53 <Wizzup> microusb port

11:53 <Wizzup> so you need the olimex thing linked above and a microusb cable you can sacrifice

11:54 <Wizzup> open them both up, and then solder three out of the four wires together, and close it up

11:54 <freemangordon> I have one cut in 2 mieces :)

11:54 <freemangordon> *pieces

11:54 <freemangordon> and ?

11:54 <freemangordon> what is the wiring?

11:55 Wikiwide has quit [Remote host closed the connection]

11:56 <Wizzup> gnd to gnd, and rx / tx to d- / d+, don't know which to which, tony has it on his website

11:56 Wikiwide has joined #maemo-leste

11:56 <Wizzup> http://muru.com/linux/d4/

11:56 <Wizzup> The wire connections are:

11:56 <Wizzup> d-device uart txusb serial rx ftdi yellow, pl2303 white

11:56 <Wizzup> d+device uart rxusb serial tx ftdi orange, pl2303 green

11:56 <Wizzup> gnddevice groundusb serial gnd

11:56 <Wizzup> vbusdo not connect

11:56 <Wizzup> I just tried rx/tx and swapped when it didn't work and then soldered when it did work

11:57 <freemangordon> ok, lemme try

11:57 <freemangordon> do I have to do anything on the device to enable that serial console?

11:58 <freemangordon> hmm, they say 3.3V

11:58 <Wizzup> no, you just need to bash keys to get it out of pm and respond

11:58 <Wizzup> but you sometimes have to plug in a few times

11:58 <freemangordon> ok

12:00 <Wizzup> I have to go, back later

12:00 <freemangordon> ok

12:21 <freemangordon> the fuck! now it works

12:21 Wikiwide has quit [Remote host closed the connection]

12:22 Wikiwide has joined #maemo-leste

12:25 Wikiwide has quit [Remote host closed the connection]

12:36 <freemangordon> ok, no idea why, but now I see no issues with poweroff/reboot

12:38 Wikiwide has joined #maemo-leste

12:41 <Wizzup> maybe you're just waiting longer now?

12:42 <freemangordon> no

12:43 <freemangordon> Wizzup: what to do to be able to see powerdown console messages?

13:29 uvos has joined #maemo-leste

13:30 <uvos> freemangordon: you need to enable the serial console in cmdline (/boot/boot/boot.cfg) and disable kernel console detach in the droid4-pm script

13:30 <uvos> note that the latter has massive pm impiclations, it compleatly breaks all low power states in the omap4
