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disable instead of outdated -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

Rip out the check from exynos_update_plane() and create exynos_check_plane() for the check phase enabling use to use the atomic helpers to call our check and update phases when updating planes.
Update all users of exynos_update_plane() accordingly to call exynos_check_plane() before.

The atomic helper to disable planes also uses the optional .atomic_disable() helper. The unique operation it does is calling .win_disable()
exynos_drm_fb_get_buf_cnt() needs a fb check too to avoid a null pointer.

Run dpms operations through the atomic intefaces. This basically removes the .dpms() callback from econders and crtcs and use .disable() and .enable() to turn the crtc on and off.
v2: Address comments by Joonyoung: - make hdmi code call ->disable() instead of ->dpms() - do not use WARN_ON on crtc enable/disable

The planes are already disabled by the drm_atomic_helper_commit() code so we don't need to disable the in these two places.

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disable instead of outdated -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()

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

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

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.
You can add my Tested-by: Tobias Jakobi tjakobi@math.uni-bielefeld.de
With best wishes, Tobias

Hi,
2015-05-09 6:51 GMT+09:00 Tobias Jakobi liquid.acid@gmx.net:
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.
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.
Kernel log is 'clean', so the series works fine for me.
You can add my Tested-by: Tobias Jakobi tjakobi@math.uni-bielefeld.de
So you didn't test it correctly yet.
Thanks, Inki Dae
With best wishes, Tobias

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()

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.
Kernel log is 'clean', so the series works fine for me.

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, Tobias

Hi,

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.
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.
I've enabled VIDI and FIMD and confirmed that they should up properly in modetest before applying the series.
This should read "...show up properly..."
Booting with the atomic series works fine, but I get a segfault when calling modetest. I've attached the kernel log below.
Kernel log is 'clean', so the series works fine for me.
You can add my Tested-by: Tobias Jakobi tjakobi@math.uni-bielefeld.de
So you didn't test it correctly yet.
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, Tobias
Thanks, Inki Dae

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.

Hi,

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.
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.
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.
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.
Thanks, Inki Dae
Kernel log is 'clean', so the series works fine for me.
You can add my Tested-by: Tobias Jakobi tjakobi@math.uni-bielefeld.de
So you didn't test it correctly yet.
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, Tobias
Thanks, Inki Dae

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.
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.
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.
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.
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.
