Jul 05 06:52:08 <KotCzarny> hmm, is there a way to make linux automatically move swapped pages from higher priority (ie. zswap) to lower priority (sdcard) depending on their age/last used/etc ?
Jul 05 07:18:12 <bencoh> KotCzarny: could be with latest kernels
Jul 05 07:18:23 <KotCzarny> bencoh: where to look for?
Jul 05 07:18:30 <bencoh> mainline that is, unless it wasn't merged, but I kind recall reading something about that
Jul 05 07:18:44 <KotCzarny> it would be also useful for my old laptop
Jul 05 07:19:40 <bencoh> bswap/zram or stuff like that I'd say
Jul 05 07:20:08 <bencoh> err, not bswap
Jul 05 07:20:27 <bencoh> zswap
Jul 05 07:22:45 <bencoh> yeah I was referring to zswap (different from zram)
Jul 05 07:29:41 <KotCzarny> well, what i'm looking at is not backing store though of zswap but swap subsystem moving pages from one swap device to another
Jul 05 07:30:02 <KotCzarny> instead of using lower priority one when higher prio is full
Jul 05 07:32:00 <bencoh> KotCzarny: then I dunno/doubt it, maybe have a look at how they do swap with ssd and whether they implemented that kind of mechanism
Jul 05 07:32:12 <bencoh> although in your case I think you'd benefit more from zswap
Jul 05 07:33:15 <Wizzup> maybe you can set up swap on bcache
Jul 05 07:33:17 <Wizzup> :D
Jul 05 07:34:10 <bencoh> yeah, bcache :)
Jul 05 07:35:52 * KotCzarny googles
Jul 05 07:36:09 <bencoh> bcache probably won't help you either here tbh
Jul 05 07:36:27 <bencoh> well, it might, but ...
Jul 05 07:36:31 <KotCzarny> yeah, it doesnt free the pages
Jul 05 07:36:33 <Wizzup> actually it probablh will, if you make a large set of small swap files
Jul 05 07:36:50 <bencoh> hm?
Jul 05 07:36:55 <Wizzup> you said you wanted to swap pages from one device to another
Jul 05 07:37:03 <Wizzup> bcache will do that based on some LRU I hope
Jul 05 07:37:19 <KotCzarny> hmm
Jul 05 07:37:52 <Wizzup> alt. maybe dm-cache? not sure if it satisfies your needs
Jul 05 07:37:57 <KotCzarny> i'm not seeing bcache into situation with swap in zram
Jul 05 07:39:16 <Wizzup> say you have /dev/fast-disk and /dev/fast-slow-disk, you could have bcache use both and them have swap on top of that?
Jul 05 07:40:22 <Wizzup> bbiab
Jul 05 07:41:51 <KotCzarny> 2 swaps: 1 in zram and 1 in mmcblk
Jul 05 07:42:30 <KotCzarny> ideally pages should be moved out of zram when unused for long
Jul 05 07:42:38 <KotCzarny> onto mmcblk one
Jul 05 07:43:09 <KotCzarny> that way memleaks would be stored in slow device and more ram available for paging
Jul 05 15:39:44 <freemangordon> DocScrutinizer05: ping
Jul 05 15:40:16 <freemangordon> DocScrutinizer05: do you know what "ccc", "npc" and "hwc" certificates are used for?
Jul 05 15:43:36 <freemangordon> KotCzarny: ^^^
Jul 05 15:43:46 <freemangordon> seems you know a bit about that
Jul 05 15:43:53 <KotCzarny> i recall that cert question 
Jul 05 15:43:59 <KotCzarny> have you checked the channel logs?
Jul 05 15:44:11 <freemangordon> yes
Jul 05 15:44:12 <freemangordon> https://mg.pov.lt/maemo-irclog/%23maemo.2016-12-17.log.html#t2016-12-17T17:59:15
Jul 05 15:45:04 <freemangordon> KotCzarny: but still, I have no idea what are those used for
Jul 05 15:45:05 <KotCzarny> nah, i'm just quite good with google (sometimes)
Jul 05 15:46:01 <freemangordon> hmm http://mobilegsm.16mb.com/reb_bb5_cpu.html
Jul 05 15:46:37 <KotCzarny> seems you have that problem since at least 2014
Jul 05 15:46:44 <freemangordon> and "ccc" seems to be Common Configuration Certificate
Jul 05 15:47:36 <KotCzarny> https://mg.pov.lt/maemo-ssu-irclog/%23maemo-ssu.2013-10-13.log.html#t2013-10-13T15:38:43
Jul 05 15:47:41 <KotCzarny> or even 2013
Jul 05 15:48:35 <KotCzarny> certificate npc appears to contain GSM IMEI, bluetooth MAC and wlan MAC
Jul 05 15:48:42 <bencoh> :)
Jul 05 15:49:13 <freemangordon> Wizzup: ^^^
Jul 05 15:49:27 <KotCzarny> seems jonwil might be most knowledgeable
Jul 05 15:49:31 <KotCzarny> see the last link
Jul 05 15:49:42 <freemangordon> KotCzarny: but what kind if cert is that, containg device specific data?!?
Jul 05 15:50:23 <KotCzarny> similar to gpg signed email?
Jul 05 15:50:34 <KotCzarny> to know it is legit
Jul 05 15:50:52 <freemangordon> hmm, seems I've asked the same question back in 2013 :D
Jul 05 15:51:42 <bencoh> yeah :D
Jul 05 15:51:55 <freemangordon> ok, still, the coversation was useful
Jul 05 15:51:56 <bencoh> means you're pretty consistent
Jul 05 15:52:13 <KotCzarny> you should take notes
Jul 05 15:52:15 <freemangordon> Am I not? :)
Jul 05 15:52:16 <KotCzarny> and put on some wiki
Jul 05 15:52:19 <KotCzarny> :>
Jul 05 15:52:28 <freemangordon> no, I'll just finish REing libsysinfo
Jul 05 15:53:25 <bencoh> for some people, REing is just easier that writing documentation ;)
Jul 05 15:53:34 <bencoh> (I'm not one of them unfortunately)
Jul 05 15:54:32 <KotCzarny> yeah, coding > writing docs
Jul 05 15:54:37 <KotCzarny> although both are important
Jul 05 15:55:56 <KotCzarny> hmm, there is something called libcal
Jul 05 15:56:54 <KotCzarny> https://bugs.maemo.org/show_bug.cgi?id=4874
Jul 05 15:57:50 <KotCzarny> and apparently its open sourced
Jul 05 15:58:30 <Wizzup> pretty sure that's already packaged and built even on leste
Jul 05 15:58:32 <KotCzarny> and interesting bits moved to closed libsysinfo, lol
Jul 05 16:06:14 <freemangordon> KotCzarny: yes, and this is what I am REing ATM
Jul 05 16:06:20 <KotCzarny> figured
Jul 05 16:06:40 <freemangordon> but I'll stop, as we'll try to live without it
Jul 05 16:07:04 <KotCzarny> try asking jonwil
Jul 05 16:07:18 <freemangordon> KotCzarny: why not join #maemo-leste? not interested in it?
Jul 05 16:07:27 <freemangordon> sure will do
Jul 05 16:07:32 <KotCzarny> i dont have autorejoin set
Jul 05 16:07:35 <freemangordon> ah
Jul 05 16:07:41 <freemangordon> then set it :p
Jul 05 16:07:50 <KotCzarny> so i have to rejoin manually after i reboot my box
Jul 05 16:08:04 <KotCzarny> sometimes i forgot channel or two
Jul 05 16:08:37 <freemangordon> it is just that it's better to keep info in one place and also more people to read it
Jul 05 16:08:52 <freemangordon> to remind me in few years :D
Jul 05 16:08:57 <bencoh> haha
Jul 05 16:24:20 <bencoh> hmm, I never heard of Sidekick 4g before
Jul 05 16:24:31 <bencoh> https://en.wikipedia.org/wiki/Danger_Hiptop#T-Mobile_Sidekick_4G_(Android/Samsung)
