Tegra DRM driver is not probing with 4.12 on tegra124

Tegra DRM driver is not probing with 4.12 on tegra124

[Paul Kocialkowski]

[-- Attachment #1: Type: text/plain, Size: 1570 bytes --]

As I was investigating why my nyan_big's screen was staying dark when testing
4.12, it appeared that the tegra drm driver does not get probed at all on my
setup (read: host1x_drm_probe never gets called). I have also tested on jetson-
tk1, with the same result.

I am using a finely-tuned out-of-tree config[0], but it appears (from looking at
the lack of drm line in the logs) that the same is happening with the tegra and
multi_v7 defconfigs hooked to kernelci.

First, I am wondering whether the tegra drm driver is probing for anyone
following this list on any tegra124 device with 4.12. If so, feel free to raise
your voice so we can find out what is wrong with my setup.

I initially thought that it was caused by missing firmwares (that are now needed
for falcon/vic support), but disabling that (by removing the &tegra_vic_driver
entry and associated compatible string in drm.c) does not help.

Hopefully, I will have time to run a bisect this week-end and identify the
commit that introduced the regression. It would be quite important to get this
fixed for the 4.13 release.

In the meantime, test results with different setups are more than welcome :)

I have bisected this to ...

    Merge tag 'v4.11-rc1' into patchwork

I am not sure if something went wrong with the above merge, but it
definitely seems to be coming from the media tree [0].

I'm seeing the same on nyan-big and jetson-tk1 with ArchlinuxARM
(linux-armv7 4.12 kernel). I sent an email to linux-tegra yesterday
about it.

Thank's for investigating and let me know if there's anything I can do to aid.

My nyan-big chromebook otherwise works very well with the ArchlinuxARM
4.11 kernel. Maybe I'll try to get the u-boot reading the eMMC so I
don't have to boot the kernel off of a USB drive...

Eh.... on the chance that this is related: I gave running 4.12 on the
Jetson TX1 a shot [1] and got "kernel BUG at
./include/linux/mm.h:466!". Nouveau's in the stacktrace. I've attached
the dmesg.
