[PATCH 0/7] drm/exynos: clean ups

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

Hi,

Here goes some clean ups to the exynos drivers. The main clean ups is
the presetting and zpos making the property immutable and the removal
of *_win_data structures.


Gustavo Padovan (6):
  drm/exynos: remove unused exynos_crtc->win_enable() callback
  drm/exynos: remove struct *_win_data abstraction on planes
  drm/exynos: preset zpos value for overlay planes
  drm/exynos: make zpos property immutable
  drm/exynos: remove exynos_plane_destroy()
  drm/exynos: remove leftover functions declarations

Mandeep Singh Baines (1):
  drm/exynos: track vblank events on a per crtc basis

[PATCH 1/7] drm/exynos: remove unused exynos_crtc->win_enable() callback

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

None of the exynos crtc drivers implements win_enable() so remove it for
better clarity of the code.

[PATCH 2/7] drm/exynos: remove struct *_win_data abstraction on planes

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

struct {fimd,mixer,vidi}_win_data was just keeping the same data
as struct exynos_drm_plane thus get ride of it and use exynos_drm_plane
directly.

It changes how planes are created and remove .win_mode_set() callback
that was only filling all *_win_data structs.

[PATCH 3/7] drm/exynos: preset zpos value for overlay planes

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

Usually userspace don't want to have two overlay planes on the same zpos
so this change assign a different zpos for each plane. Before this change
a zpos of value zero was created for all planes so the userspace had to
set up the zpos of every plane it wanted to use.

Also all places that were storing zpos positions are now unsigned int.

[PATCH 4/7] drm/exynos: make zpos property immutable

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

We already set each plane zpos at init, after that changes to zpos are
not expected. This patch turns zpos into a read-only property so now it is
impossible to set zpos.

It's a good idea for a hardware overlay to a plane object isn't changed
by user-space. However, this patch would make the compatibility of the
existing application - using set_property ioctl to change hardware
overlay to particular plane - to be broken because the set_property
ioctl request will always be failed without the set_property callback.

So how about leaving warning message 'the hardware overlay cannot be
changed to another anymore' when the set_property ioctl is requested by
user-space, and returning just 0?

Thanks,
Inki Dae

[PATCH 5/7] drm/exynos: remove exynos_plane_destroy()

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

The .destroy() callback for exynos can be replaced by drm_plane_cleanup().
The only extra operation on exynos_plane_destroy() was a call to
exynos_plane_disable() but the plane is already disabled by a earlier call
to drm_framebuffer_remove().

[PATCH 6/7] drm/exynos: remove leftover functions declarations

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

These functions were already removed by previous cleanup work, but these
ones were left behind.

[PATCH 7/7] drm/exynos: track vblank events on a per crtc basis

[Gustavo Padovan]

From: Mandeep Singh Baines <msb@chromium.org>

The goal of the change is to make sure we send the vblank event on the
current vblank. My hope is to fix any races that might be causing flicker.
After this change I only see a flicker in the transition plymouth and
X11.

Simplified the code by tracking vblank events on a per-crtc basis. This
allowed me to remove all error paths from the callback. It also allowed
me to remove the vblank wait from the callback.

With your cleanup patch set, the plane test doesn't work. Have you ever
tested plane feature with modetest application?

I typed like below and it looks like no problem but I cannot see
anything on Panel except for cute four penguins.

# modetest -P 29:100x100+0+0
trying to open device 'i915'...failed.
trying to open device 'radeon'...failed.

trying to open device 'vmwgfx'...failed.
trying to open device 'omapdrm'...failed.
trying to open device 'exynos'...success.
testing 100x100@XR24 overlay plane 25

And for two plane test,

# modetest -P 29:100x100+0+0 -P 29:100x100+0+100
trying to open device 'i915'...failed.
trying to open device 'radeon'...failed.

Okay, I'll check on that. I was using a test app we wrote here.
I'll test this again with modetest too.

Well, I did some more testing and even without my patches I can't see a plane
on the screen. Running only on exynos-drm-next also doesn't work so it is not
something that my patches introduced, it is already a bug upstream.
I'm using a snow for testing.

It's strange. I can see a semicircular small box on the screen without
your patch set, and that works well on not only exynos-drm-next but also
exynos-drm-fixes. I'm using a trarts2 board based on Exynos4412 SoC.

Could anyone check the plane test with modetest for double-check?

[PATCH 0/7] drm/exynos: clean up patches (preparing for atomic)

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

Hi,

Here goes some clean ups to the exynos drivers. The main clean ups is
the presetting and zpos making the property immutable and the removal
of *_win_data structures.

Gustavo Padovan (6):
  drm/exynos: remove unused exynos_crtc->win_enable() callback
  drm/exynos: remove struct *_win_data abstraction on planes
  drm/exynos: preset zpos value for overlay planes
  drm/exynos: make zpos property immutable
  drm/exynos: remove exynos_plane_destroy()
  drm/exynos: remove leftover functions declarations

  drm/exynos: track vblank events on a per crtc basis

[PATCH 4/7] drm/exynos: make zpos property immutable

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

We already set each plane zpos at init, after that changes to zpos are
not expected. This patch turns zpos into a read-only property so now it is
impossible to set zpos.
