<geecko> hey xplodwild, do you think updating s3cfb in the kernel would possibly remove all the screen tearing we see ?
<geecko> xplodwild, it's particularly noticable with the kitkat launcher. if you swipe to the left and giggle it, you'll see tearing at the bottom right of the cards
<xplodwild> hmm not sure
<sbrissen> I get it on screen rotations

<geecko> sbrissen, omni or cm?
<sbrissen> cm
<Espenfjo> I wouldnt bet too much on s3cfb
<geecko> Espenfjo, what is the safest bet then?
<sbrissen> xplodwild: the coloring issue i had yesterday has to do with the legacy egl commits. I wasn't using them
<geecko> Espenfjo, also what is the exact purpose of s3cfb? managing the display, in which way?
<Espenfjo> It manages the framebuffer/display
<Espenfjo> hardware part of it
<Espenfjo> Note sure what it could be. some new egl stuff somewhere perhaps
<geecko> Espenfjo, this issue appeared a while ago. i think from android 4.2
<geecko> Espenfjo, 4.1 was utter slow but i don't remember tearing like this
<Espenfjo> Thats probably from something else entirely
<geecko> Espenfjo, at least it's not from the mali drivers :P
krabador has joined #teamhacksung
<geecko> Espenfjo, i'll try to update s3cfb and report :)
<geecko> Espenfjo, by the way you advice "copy and fix everything that derps" for mali was very useful :D
<Espenfjo> :)
<Espenfjo> Been there, done that
<Espenfjo> ump, mali and s3cfb
<Espenfjo> s3cfb is a bit detached from them, but it all melts together
<geecko> Espenfjo, one more reason to work on it
<Espenfjo> sbrissen: Do you get it on overlays? volume overlay for example?
<sbrissen> nope
<Espenfjo> Ok

<geecko> basically new panels support
<geecko> i see references to "fences"
<geecko> i think it's the thing that was needed by the hwcomposer from insignal
<geecko> doesn't compile though
<geecko> there's some updates needed in arch/arm/mach-exynos
<sbrissen> yea the new r3p2 drivers and libs support fencinf
<sbrissen> fencing
<geecko> sbrissen, exciting
<xplodwild> geecko: keep me tuned
<geecko> xplodwild, sure!

<geecko> aw, seems to compile
<geecko> yes it does!
<geecko> some header issue
<geecko> xplodwild, it boots... lemme check the rest
<geecko> xplodwild, glitches still here.
<geecko> i'm using r3p1 drivers though
<geecko> sbrissen Espenfjo
Epsylon3 has quit [Ping timeout: 252 seconds]
<Espenfjo> same glitches, or glitches on overlays (volume menu thingie)@
<geecko> Espenfjo, i see checkboard-like glitches sometimes when switching between apps (like clicking a link on twitter brings me to the browser)
<Espenfjo> Use your volume buttons and increase or decrease the volume
<geecko> xplodwild, this commit was overriden by the changes, and yet i fail to see a difference... https://github.com/GeeckoDev/raw_kernel/commit/c1713e6a8fc8c346fb90581e815a5298ecc0595d
<geecko> Espenfjo, i'm on cm 10.2 right now, and there's no issue here
<Espenfjo> kk
lolwat has quit [Read error: Connection reset by peer]
<geecko> holy shit
<geecko> i was on the wrong branch .....
<geecko> forget everything i say, Espenfjo xplodwild
<geecko> that was too easy ;)
<geecko> so there's still hope ^_^
<geecko> weird, samsung deleted s3cfb_lcd definition from a header, but it's still used at another place in update12... i fail to see how it compiles properly

<geecko> xplodwild, Espenfjo, got it compiling, for real this time :)
<geecko> xplodwild, HAHA! it runs approximately at 1fps now :P
arcus has joined #teamhacksung
<Espenfjo> Missing vsync then.. :)
<Espenfjo> Been there done that
gladiac1337 has joined #teamhacksung
<Espenfjo> Yes, should be. Havent looked at the hwcomposer, but it should use sysfs too
<geecko> "W/SurfaceFlinger( 1885): Timed out waiting for hw vsync; faking it" <- that's it!
<sbrissen> the vsync stuff is in the updated s3cfb driver, just the sysfs changed, vsync_time vs vsync_event_show
<geecko> sbrissen, so what should i do
<sbrissen> er vsync_event not show. probably easiest to change the path for hwc to find the vsync events
<geecko> sbrissen, ok, i spotted it.
Kaik541 has quit [Ping timeout: 240 seconds]
<geecko> halp
Rebellos has joined #teamhacksung
<geecko> sbrissen, Espenfjo, should vsync_time show in /dev ?
<sbrissen> current one is /sys/devices/platform/samsung-pd.2/s3cfb.0/vsync_time
<geecko> thx
<geecko> sbrissen, there's nothing in here ...
<geecko> ls, driver, fimd_dump, etc etc, but no vsync_event or vsync_time
<sbrissen> cd to /sys then run find . -name vsync_event
<geecko> ./devices/platform/samsung-pd.2/s3cfb.0/graphics/fb0/vsync_time
<geecko> ... needs userspace changes?
kti_ has quit [Ping timeout: 250 seconds]
<sbrissen> update hwc there then
<Espenfjo> hwc if anything, but perhaps better to change the kernel?
<sbrissen> i thought hwc just to stay inline with samsung's kernel source
<geecko> sbrissen, yes. however i don't have the ressources to compile it right now, i would need the whole source tree
<geecko> xplodwild, halp :)
<Espenfjo> sbrissen: hm.. yeah, perhaps.
<Espenfjo> Was thinking about compatibility with ofther exynos4 kernels.
<xplodwild> ^
<geecko> can i "ln -s" as a quick workaround to test? :D
<Espenfjo> no
<Espenfjo> sysfs is read only
<Espenfjo> or.. well.. not really
<Espenfjo> but you cant create nodes there
<Espenfjo> Fastest test is to change hwc, push then kill surfaceflinger
<Espenfjo> should reload everything thats needed
<geecko> Espenfjo, i can't
<geecko> Espenfjo, xplodwild, anyway if you guys wanna test it with a proper hwcomposer, everything is here: https://github.com/GeeckoDev/raw_kernel/commits/raw-10.2-s3cfb
<geecko> ret = device_create_file(fbdev[i]->fb[pdata->default_win]->dev, &dev_attr_vsync_time);
<geecko> i could change the path here, but how... i want to test
<geecko> oh, ok. it's not just a path change, it belongs to another device, hence the subfolders
<geecko> good luck to change that
<Espenfjo> :)
<geecko> wait no :D
<geecko> ret = device_create_file(fbdev[i]->dev, &dev_attr_vsync_time);
<geecko> file is placed right, but it still doesn't work
<geecko> Espenfjo, ?
<geecko> now i don't understand...
<sbrissen> any times being put into that file?
<geecko> sbrissen, yep
<geecko> shell@GT-N7000:/sys $ find . -name vsync_time
<geecko> ./devices/platform/samsung-pd.2/s3cfb.0/vsync_time
<geecko> 253456978896
<geecko> shell@GT-N7000:/sys $ cat ./devices/platform/samsung-pd.2/s3cfb.0/vsync_time
<geecko> fuuuuuu-
<geecko> Espenfjo, sbrissen, forgot to modify sysfs_notify :D
<sbrissen> :-P
<geecko> IT FUCKING WORKS
<geecko> and there's still these glitches, ha
<Espenfjo> Probably some EGL mismatch in mali, or some new format somewhere

Epsylon3 has joined #teamhacksung
<Epsylon3> hi there, does somebody made work on MHL on exynos 4 ?
<Epsylon3> (on non stock rom)
<Espenfjo> I would say probably not
<Epsylon3> its made in some samsung libs ?
<Epsylon3> im not familiar with that, except on tegra2
<Epsylon3> and it was a real hdmi output
<Espenfjo> MHL/TVout has never really worked on the exynos4 devices. There has been very little effort on it since gb/ics, but it might be possible now with newer revisions of insignal sources
<Epsylon3> do you know the chip reference in S3 / Note 2 ?
<Epsylon3> my previous device was a galaxy r, and even on stock rom it was never implemented
<Espenfjo> No, dont remember it
dan408__ has joined #teamhacksung
<dan408__> hi
<geecko> Espenfjo, if it was a format mismatch, would it glitch *everytime*
<geecko> hi dan
<dan408__> hi geecko
<dan408__> im trying to figure out how to build cm for espresso10att

<rhcp> interesting a few people got builds of S4 VZW 4.4 going
<rhcp> data + bt and other stufff
<rhcp> ive yet to see a build though. i wonder what doesnt work
<codeworkx> E3-x264: mhl... some samsung libs. what would you say if i tell you that "vold" is part of the mhl mess?
<codeworkx> rhcp: 4.4 is working fine here
<rhcp> hook up a build for VZW for me :)
<rhcp> I tried to build it. did not work
<codeworkx> nexus 5 :-P
<rhcp> oh
<rhcp> too many people saying its craptastic
<rhcp> they are already going on ebay/swappa
<rhcp> you dont even see any nexus5 tweets anymore
<codeworkx> much plastic. but hey, look through the crapsung phones
<rhcp> I heard the battery sux
<rhcp> camera sux
<rhcp> and the china IPS display on that oppo is 10x better
<codeworkx> cam got much improved compared to n4
<rhcp> so much for google + flagship
<rhcp> well it sucked on the N4 too
<rhcp> lol
<rhcp> i think the S4 (once hacked and CM'ed) is more of a nexus then a nexus
<rhcp> if you ask me
<codeworkx> lol
<rhcp> and you get SD
<rhcp> vs no sd
<codeworkx> another lol
<rhcp> I never got the idea why they dont put an SD card on the nexus devices
<codeworkx> i bought the 16gb one. even 8gb would be enough
<rhcp> I was THINKING to buy one. but i cant use it
<rhcp> the only way i could use it. is if i was willing to go to TMO
<rhcp> and deal with their craptastic service
