10:54 <zombah> hello, anyone know is it possible to somehow override black screen problem on exynos525-snow with linux-stable kernel 3.19/3.19.1?

11:00 <javier__> zombah: not all the needed patches for display on Snow made it to 3.19

11:05 <javier__> zombah: so you will need to cherry-pick all Ajay's drm bridge and DTS patches that were merged for 4.0

11:12 <zombah> javier__: oh i see! thought maybe it is fixable by config changes

11:13 <javier__> zombah: unfortunately for snow is not since the support for the eDP/LVDS bridge is not in 3.19

11:15 <javier__> which reminds me that I've to send the patch to rever the disp1 pd DT patch to have display working on snow/spring again

11:18 <zombah> will it land to 4.0 release or only to 4.0.1?

11:23 <javier__> zombah: Ajay's drm patches are already in 4.0 but unfortunately kukjin didn't pick his DTS patches so most likely 4.1

11:23 <javier__> zombah: but having it working in 4.0 will be a matter of cherry-picking one patch

11:25 <zombah> javier__: thanks for info, only one patch is good enough

11:26 <javier__> zombah: you are welcome

11:41 <zombah> javier__: the missing patch is from this series http://www.spinics.net/lists/linux-samsung-soc/msg41403.html ?

11:44 <javier__> zombah: yes, "[PATCH V9 13/14] ARM: dts: snow: represent the connection between bridge and panel using videoport and endpoints

11:45 <javier__> zombah: but kukjin changed ajay's subject to "ARM: dts: represent bridge and panel connection for exynos5250-snow"

11:45 <javier__> so that is how it ended in mainline

11:47 <zombah> javier__: thanks again, now im ready for 4.0 release 8)

11:50 <javier__> zombah: not quite, there are a couple of issues still... you need commit 6562f3bd396a ARM: exynos_defconfig: Disable IOMMU support

11:50 <javier__> zombah: that was merged in linux-next but not in 4.0-rc3 (I asked serval times to kukjin to pick that one but didn't do it)

11:51 <javier__> zombah: and also you need to revert commit 2d2c9a8d0a4f ARM: dts: add display power domain for exynos5250

11:52 <javier__> I'll post a patch today to do that and ask to make it for 4.0-rc cycle but the exynos maintainer sometimes takes weeks to merge stuff...

11:53 <javier__> zombah: hrm, forget about the last revert, the offending commit is in linux-next but didn't make it to 4.0-rc

11:53 <javier__> so you won't need that one

12:20 <zombah> javier__: i think previous one i also don't need, openSUSE use custom kernel config based on multi_v7_defconfig i think not exynos_defconfig

12:21 <javier__> zombah: oh, cool

12:21 <javier__> yeah, if you are using a custom defconfig then is just a matter of making sure that your distro has all the needed kconfig symbols enabled

12:22 <javier__> or disabled in the case of exynos iommu

12:24 <zombah> javier__: yes, i think i need to test linux-next right now to see it works or not

12:35 <javier__> zombah: ok, for linux-next you will need the revert I mentioned though ^

13:47 <afaerber> javier__, zombah: which kconfig symbols?

13:49 <javier__> afaerber: I just mentioned zombah that exynos drm iommu is broken on (at least) exynos5 so you need to disable that

13:51 <javier__> afaerber: 6562f3bd396a ("ARM: exynos_defconfig: Disable IOMMU support") is in linux-next for exynos_defconfig

14:09 <zombah> afaerber: this config variable is not set in current factory openSUSE kernel lpae config, so i think it is ok for now

15:54 <si1v3r> javier__: I did not disable iommu in 4.0rc4 and it still boots.

15:57 <javier__> si1v3r: strange, you should needed after commit 8dcc14f82f06 ("drm/exynos: IOMMU support should not be selectable by user") which made to v4.0-rc1

15:58 <javier__> si1v3r: oh, but you are running linux-next right? you don't need to disable there because the mentioned commit ^^ already does to exynos_defconfig

15:59 <si1v3r> yeah I thought it was broken and then fixed.

15:59 <si1v3r> I needed to disable it in rc2 I think

15:59 <javier__> si1v3r: nod, but zombah was asking about 4.0 not linux-next

15:59 <si1v3r> sorry. :)

15:59 <javier__> si1v3r: no worries :)

15:59 <javier__> so many issues that is hard to keep track what made to each version...

17:17 <daniels> javier__: you forgot this one - https://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg42861.html

17:27 <javier__> daniels: oh, right. that too!

17:27 <daniels> unfortunately it seems to have fallen on deaf ears

17:27 <javier__> I've it on my lists of patches to keep track though

17:27 <daniels> woo :)

17:27 <daniels> ta

17:28 <javier__> daniels: so I'll keep pestering inki :)

18:46 <zombah> a
