Hello,
I did another run with drm.debug=0xff and also tried to figure out where
the div-by-zero comes from.
The only division I see is in fimd_calc_clkdiv() (which is called by
fimd_commit()). So it looks like 'ideal_clk' is zero when calling
DIV_ROUND_UP().
'htotal' and 'vtotal' can't be zero, since this is checked early in
fimd_commit(). So 'vrefresh' has to be zero. Maybe this helps?
With best wishes,
Tobias

vrefresh can legitimately be zero, which makes this FIMD_DEFAULT_FRAMERATE
assignment problematic rather than harmless.
If it's zero, you can find a vrefresh value with drm_mode_vrefresh, which
will calculate it for you.

So better try this. Ideally fimd_mode_fixup should go away too, I'll do a proper
patch once we know this works.

I've applied this and the debug output patch, but I still get a
div-by-zero.

Can you please add a drm_mode_debug_printmodeline(mode) and give the
output there?

I've also added printk for ideal_clk, here's the output.
kernel output:
[ 81.204682] [drm:fimd_calc_clkdiv] vrefresh 0
[ 81.204700] [drm:drm_mode_debug_printmodeline] Modeline 0:"1366x768"
0 500 1366 1414 1446 1526 768 771 776 790 0x48 0x5
[ 81.204710] [drm:fimd_calc_clkdiv] ideal_clk 0
So vrefresh remains zero after all.
With best wishes,
Tobias

OK,
so Daniel helped me track down this issue. It came from an incorrect
'clock-frequency' entry in my DTS. The freq was 500000. Daniel
recommended 70600000 which works 'fine' (and according to modetest
produces a 59Hz mode). I say 'fine' because I can't confirm that FIMD is
actually working. I just see that with that change I no longer get any
div-by-zeros in the kernel.
So fimd_calc_clkdiv needs some sanitizing for 'ideal_clk' at least.
What still bothers me though is the fact that FIMD actually gets
enabled. I'm just calling 'modetest -M exynos', so it's just doing
probing. Why does that trigger dpms?
With best wishes,
Tobias

That is good to hear! So maybe we are now ready to have the atomic
modesetting patches merged in. I'll send a new version with the last
fix to avoid crashes with null CRTC.

That comes from restore_fbdev_mode() when modetest closes the file
descriptor, but I'm not sure why a update happens at this time.

Indeed. Though as he says below:
>> So fimd_calc_clkdiv needs some sanitizing for 'ideal_clk' at least.
It would be nice to:
a) reject any mode with an impossible clock in mode_valid (filter
connector modes) + mode_fixup (explicit request)
b) WARN_ON and return during FIMD commit if clk_div ends up being zero

It comes from lastclose: when the last client exits, DRM tries to
restore the mode that fbcon was using. Quite why it didn't fail before
this point (i.e. when doing it initially), I'm not quite sure, but oh
well.
Cheers,
Daniel

I suspect that atomic merely exposed this bug (I suspect it was there
all the time).

The weird thing is that it works quite fine on my exynos 5 hardware.
I'll take a look on what could be be happening to cause this kind of
crash.

Below panic issue is same as one I faced with at previous patch seris,
v3, which was invalid memory access - state->crtc is NULL whille
modetest is being performed. It seems that the last patch of v4 didn't
resolve this issue yet.

And here's the drm.debug=0xff output leading to the oops:

I've tried to do this in userspace by running modetest through gdb, but
I can't seem to break when the segfault occurs (modetest is already dead
when gdb attempts to break).
I hope this makes it easier to isolate the issue.
With best wishes,
Tobias

I've enabled VIDI and FIMD and confirmed that they should up properly in
modetest before applying the series.
Booting with the atomic series works fine, but I get a segfault when
calling modetest. I've attached the kernel log below.

I tested the common usage scenario. In fact I can't really test with
FIMD anyway, since I don't have any panel that I can attach to the LCD
expansion port. Regardless of whether the kernel oopses or anything with
atomic, I can never make sure that the FIMD visuals are actually correct.
With best wishes,

As I mentioned several times, it works well in case that only one crtc
driver is enabled. Could you check it again after you enable two or
more crtc drivers such as FIMD and HDMI or FIMD, HDMI and VIDI
together? For this, dts file for X2 should contain their device nodes
and also should be configurated though menuconfig.

So you didn't test it correctly yet.

Hello,
I've tested this on my Hardkernel Odroid-X2 (connected via HDMI to a
1080p panel).
Run the usual modetest tests (just primary plane, primary plane with
vsync, primary plane with overlay, primary plane with overlay and video
overlay, overlay partially outside of crtc area, etc.) and haven't
noticed any issues so far.
Kernel log is 'clean', so the series works fine for me.

Don't the last patch of series in v4 fixes this? I think it can fixes
those issues, but I can't test here as I don't have the hardware.

Thanks for moving it to -next-todo

You need to resolve one issue that booting is still halted when one more
crtc drivers are enabled, which is a dead lock issue incurred by
register_framebuffer call. For this, I pointed out already at v3.
The last patch may resolve invalid memory access which state->crtc had
NULL while modetest is being performed but it didn't resolve above
booting halt issue.
So as of now, I have merged this patch series for more reviews to
exynos-drm-next-todo yesterday. I will move them to exynos-drm-next if
the issue is resolved.
Thanks,
Inki Dae

Hi Inki and Joonyoung.
Any thoughts on this?

Hi,
Here goes the full support for atomic modesetting on exynos. I've
split the patches in the various phases of atomic support.
v2: fixes comments by Joonyoung
- remove unused var in patch 09
- use ->disable instead of outdated ->dpms in hdmi code
- remove WARN_ON from crtc enable/disable
v3: fixes comment by Joonyoung
- move the removal of drm_helper_disable_unused_functions() to
separated patch
v4: add patches that remove unnecessary calls to disable_plane()
Gustavo
