Below is the booting logs, [ 1.171318] console [ttySAC2] enabled [ 1.175522] 13830000.serial: ttySAC3 at MMIO 0x13830000 (irq = 60, base_baud = 0) is a S3C6400/10 [ 1.185545] [drm] Initialized drm 1.1.0 20060810 [ 1.194104] exynos-drm exynos-drm: bound 11c00000.fimd (ops fimd_component_ops) [ 1.200352] exynos-drm exynos-drm: bound 11c80000.dsi (ops exynos_dsi_component_ops) [ 1.207688] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

This patch looks good to me so I tried to find why locked up and I found the booting is locked up as soon as console_lock function is called. Can you and other guys look into this issue?

I've realized that I left a fix for patch 01 behind, it could be the cause of this issue. I've just resent this patch with the added v2 fix up. Gustavo

With above change, still locked up. So your updated patch doesn't resolve this issue. Anyway, I tested it with fbdev emulation relevant patch series[1] and the booting was ok with disabling fbdev emulation as Daniel commented. However, I think the booting should also be ok with fbdev emulation so I don't want for your last patch to be merged to mainline until the issue is resolved.

Without fbdev you need to start a kms client (X, whatever) to force a modeset. Otherwise you won't reproduce anything. And sometimes it requires a bit of trickery to create a sequence of modeset calls which exactly match what fbcon would do. -Daniel > > [1] http://www.spinics.net/lists/dri-devel/msg86617.html > http://lists.freedesktop.org/archives/dri-devel/2015-March/078975.html > > Thanks, > Inki Dae > > > > > Gustavo > > -- > > To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in > > the body of a message to majordomo@vger.kernel.org > > More majordomo info at http://vger.kernel.org/majordomo-info.html > > > > _______________________________________________ > dri-devel mailing list > dri-devel@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/dri-devel

Without fbdev, modeset never be performed at booting time. However, without fbdev, we cannot use text console and that is definitely a problem. Thanks, Inki Dae > modeset.

I've tried to reproduce your issue with these patches on a odroid-x2 (exynos4412) but it seems to work fine for me with fbdev emulation enabled. In snow and peach-pi it also works fine. We would need to debug better on your side to figure out what is breaking for you. Gustavo

Did you test odroid-x2 with LVDS based Display panel? If so, it's not different because I tested it with Trats2 board with MIPI-DSI + Display panel. AFAIK, Odroid-x2 board doesn't support MIPI-DSI panel. I will have a pull request soon without 11/11. After that, I think we could find and resolve the issue later.

Ah, I thougth your talking about whole patchset! I think I figured out what was happend the .mode_fixup() and .mode_set() helpers for the DSI drm_encoder was not set and leading to a null pointer at some pointer. That is problably what you were experiencing. Could you please try the new version of patch 11/11 that I've just sent to the mailing list? And thanks for merging these patches! Gustavo
