<prahal> I always get oops on end-of-stream from s5p-mfc . Who should I bug report to ? (kernel 4.16-rc4 mfc v5 exynos 4412 odroidu)
<ahajda> You can use linux-media@vger.kernel.org and linux-samsung-soc@vger.kernel.org mailing lists to report it, generally for kernel drivers you can use:
<ahajda> ./scripts/get_maintainer.pl drivers/media/platform/s5p-mfc/ , please describe steps to reproduce and environment
<prahal> nvm I noticed I have Tobias s5p-mfc patches , will try without before bugging everybody in maintainer list :)
<prahal> the report is ready to ship ! but I will hold it a little

<PabloPL> mszyprow: Got wifi working on Aries (with few other things)
<mszyprow> PabloPL: nice
nighty- has quit [Quit: Disappears in a puff of smoke]
<mszyprow> PabloPL: it would be nice if you send all your patches to mainline :)
<PabloPL> and i know why radio (si470x) is not working - broken driver :/
<PabloPL> since 3.5 kernel
<mszyprow> PabloPL: then fix the driver ;)
<mszyprow> PabloPL: it should not be that hard to fix it once you know which commit causes the issue
<PabloPL> mszyprow: I also need some patches from tom3q (onenand and fimd)
<mszyprow> PabloPL: no problem to submit also them
<mszyprow> PabloPL: it's fine to submit patches from someone else
<PabloPL> Probably this commit, because now it's failing at video_register_device, and looking at code i saw that radio->v4l2_dev is not set)
<PabloPL> mszyprow: I'm using s5pv210_defconfig but today i saw that it's possible to use multi_v7_defconfig also. Should i switch to this defconfig ?
<mszyprow> PabloPL: for your case s5pv210_defconfig is better
<mszyprow> multi_* defconfigs are a base for distro makers
<mszyprow> they support more than one hw archs
<mszyprow> so more drivers are compiled into the kernel
<mszyprow> longer compilation
<PabloPL> and missing for example exynos3 (3250 maybe)
<PabloPL> in case for example multi_v7
<PabloPL> mszyprow: Do you know what will happend with g2d/jpeg drivers? old ones in video has support for s5pv210 but new one in drm/ don't
<mszyprow> there is no jpeg driver in drm
<mszyprow> in case of g2d, the drm driver was rewritten from scratch
<mszyprow> and it supports much more features offered by g2d hw
<mszyprow> so X/wayland can use it for hw acceleration
<mszyprow> but I don't remember the differences between g2d in s5pv210 and exynos4
<PabloPL> so old ones will be dropped probably? and for new ones "someone" would need to add support for it
<mszyprow> that would be the best solution
<mszyprow> as the v4l2 g2d driver is very limited
<mszyprow> basically it offers only simple blits
<mszyprow> noting more
<PabloPL> here was a patch for this, but not sufficient
<mszyprow> you also would need to add respective userspace code for g2d/s5pv210 hw in libdrm/exynos/ if you want to switch to drm g2d driver
<mszyprow> but that definitely the right way of using g2d hw
<PabloPL> Is here anyone using kgdb?
<PabloPL> I'm having problems with using it on s5pv210
<mszyprow> not here right now

<PabloPL> maybe someone will know the answer how to fix it (tried also ubuntu gdb and the same error)
<forkbomb> mszyprow: do you guys have any plans to submit a new version of the trats2-audio stuff?
<mszyprow> forkbomb: right now it is only on the todo list and noone works on it, if you have time and wish to port the driver from the older kernel (i.e. Tizen v3.10) then feel free to do it :)
<mszyprow> forkbomb: I don't know if there were any significant api changes there
<forkbomb> cool, i'll have a go :)

<mszyprow> forkbomb: btw, you may also check if there are any other drivers in the https://git.tizen.org/cgit/platform/kernel/linux-3.10/ tree, which didn't get into mainline
<forkbomb> modem_if :P
<mszyprow> forkbomb: if I remember correctly, that tree was quite complete and already based on dt (although on the early version of some bindings and work-in-progress code)
<forkbomb> i think it's mostly all there for trats2/i9300
<forkbomb> mszyprow: yeah, it seems pretty complete
<forkbomb> maybe NFC isn't supported?
<mszyprow> afair it was working
<forkbomb> uh, i mean in mainline
<mszyprow> ah, right, mainline might lack it
<forkbomb> i have patches for touchkey locally, which i should submit
<mszyprow> and one need to check rgb leds
<forkbomb> oh, i submitted a driver for that
<mszyprow> okay, then I missed it
