The patch replaces separate calls to driver (de)registration by
loops over the array of drivers. As a result it significantly
decreases number of ifdefs. Additionally it moves device registration
related ifdefs to header file.

Hi Inki,
During testing your component match support patch [1] I have prepared patch
removing most ifdefs from exynos_drm_drv.c. It is based on your patch, but
I can rebase it if necessary.

Hi Andrzej,
I merged it to local repository to test. But now exynos drm doesn't work
correctly since pulling drm-next of Dave regardless of your patch.
Problems are,
1. error occurs when we try to test modetest with -v option from second
times.
2. error occurs when we try to test unbind.
Now we are checking these problems. Can you try to also check it?
Thanks,
Inki Dae

Hi Andrzej,
I merged it to local repository to test. But now exynos drm doesn't work
correctly since pulling drm-next of Dave regardless of your patch.
Problems are,
1. error occurs when we try to test modetest with -v option from second
times.
2. error occurs when we try to test unbind.
Now we are checking these problems. Can you try to also check it?
Thanks,
Inki Dae

I face a similar issue. For me, modetest -v doesn't work for the first try also.
I tried to test on snow and peach_pit.
modetest returns with following error from drm_crtc.c:
if (crtc->primary->fb->pixel_format != fb->pixel_format) {
DRM_DEBUG_KMS("Page flip is not allowed to change
frame buffer format.\n");
ret = -EINVAL;
goto out;
}
This has started coming since 3.15 I think.

I face a similar issue. For me, modetest -v doesn't work for the first try also.
I tried to test on snow and peach_pit.
modetest returns with following error from drm_crtc.c:
if (crtc->primary->fb->pixel_format != fb->pixel_format) {
DRM_DEBUG_KMS("Page flip is not allowed to change
frame buffer format.\n");
ret = -EINVAL;
goto out;
}
This has started coming since 3.15 I think.

The patch disables vblanks during dpms off only if pagefilp has
not been finished. It also replaces drm_vblank_off with drm_crtc_vblank_put.
It fixes issue with page_flip ioctl not being able to acquire vblank counter.

Hi Inki,
This is fix (or just workaround) of the problem you have reported.
Please carefully verify it, as I am not familiar with pageflip code.
Regards
Andrzej

This problem isn't related with pageflip, it just causes from
7ffd7a68511c710b84db3548a1997fd2625f580a commit (drm: Always reject
drm_vblank_get() after drm_vblank_off()).
We need to use drm_vblank_on() as a counterpart to drm_vblank_off()
after the commit .
How about below patch?

Thanks you Joonyoung and Andrzej,
drm_vblank_on/off() are legacy api so it would be better to use
drm_vblank_crtc_on/off functions instead.
And drm_vblank_crtc_off() makes sure that the latest vblank frame count
is stored and restored by drm_vblank_crtc_on() again. So my opinion is,
static void exynos_drm_crtc_dpms(struct drm_crtc *crtc, int mode)
{
[snip]
if (mode > DRM_MODE_DPMS_ON) {
/* wait for the completion of page flip. */
if (!wait_event_timeout(exynos_crtc->pending_flip_queue,
!atomic_read(&exynos_crtc->pending_flip),
HZ/20))
atomic_set(&exynos_crtc->pending_flip, 0);
drm_crtc_vblank_off(crtc); //<- store the latest vblank frame count.
} else {
drm_crtc_vblank_on(crtc); //<- restore the vblank frame count.
}
[snip]
}
Tested and worked well with above patch. How about it?
Thanks,
Inki Dae

This patch should break also other drivers, it seems at least following
drms could be affected:
armada, sti, tegra.
I guess after disabling and re-enabling crtc vblanks should stop
working, unless there are other bugs.

Indeed we (tegra) have just been hit by this. The problem seems to come
from the fact that we have been using drm_vblank_pre_modeset,
drm_vblank_post_modeset and drm_vblank_off conjointly. All these
functions depend on the value of vblank->inmodeset, and 7ffd7a68511
increases the vblank reference counter only in drm_vblank_off, which can
result in the acquired reference never being released.
The following seems to fix this for Tegra, by stopping using
drm_vblank_pre/post_modeset and relying on drm_vblank_off/on instead:

Thierry, does this look ok to you?
But there might be another issue, which is that calls to
drm_vblank_get() will return -EINVAL if invoked between drm_blank_off
and drm_blank_on. Is this really the desired behavior? Can it at least
happen? If so, how are drivers supposed to react to this situation?

I've not yet seen the commit which causes this problem, but I hope
that drm_wait_vblank() isn't affected by this. In current mainline,
drm_vblank_get() is used inside drm_wait_vblank(), which is called as
a result of userspace calling DRM_IOCTL_WAIT_VBLANK.
So, what is the effect of this change on user applications making use
of the vblank wait ioctl - and is that change intended?

There's no effect on user applications if the driver behaves properly.
As far as I can tell, every driver that calls drm_vblank_off() but not
drm_vblank_on() will break. You can easily test this by running libdrm
modetest -s ... -v, which instead of toggling between the test pattern
and an all-gray framebuffer will switch to the gray one once and then
hang.
I guess that was probably not intended, but according to the new rules
all these drivers have now become buggy. So before merging this patch I
think we need to fix existing drivers to avoid regressions.

Yes, that looks like almost the same patch that I sent out yesterday.
The difference is that I didn't replace the drm_vblank_pre_modeset()
call with drm_vblank_off() like you did, but rather just dropped the
former.
I /think/ your version is more correct in that regard.

It shouldn't happen. If drm_vblank_off() and drm_vblank_on() are called
around a modeset they should never conflict with drm_vblank_get(), at
least on Tegra, because the modeset and page-flip IOCTLs will be
serialized.

Feel free to take that extra line in your patch then. ;)

Ok, that's good. I was just wondering whether this case has been thought of.
Actually, and seeing how drm_vblank_pre/post_modeset() have become
useless (if not harmful), maybe it would be a good idea to come with a
fixup patch that gets rid of them altogether and make their callers
invoke drm_vblank_off/on() instead?

drm_crtc_vblank_on should be called after dpms on, otherwise it can fail enabling vblank. I have provided
full explanation in my other email [1].
You can modify your patch or just use the one provided in [1].

* [PATCH] drm/exynos: remove ifdeferry from initialization code
2014-10-30 13:02 ` Inki Dae

From: Andrzej Hajda @ 2014-10-30 13:13 UTC (permalink / raw)
To: Inki Dae; +Cc: Andrzej Hajda, dri-devel
The patch replaces separate calls to driver (de)registration by
loops over the array of drivers. As a result it significantly
decreases number of ifdefs. Additionally it moves device registration
related ifdefs to header file.
Signed-off-by: Andrzej Hajda <a.hajda@samsung.com>

Hi Inki,
Rebased on the latest exynos-drm-next.

Andrzej
