From: Shawn Guo <shawn.guo@linaro.org>
The vblank is mostly CRTC specific and implemented as part of CRTC
driver. Let's keep the vblank hooks struct drm_driver for legacy
drivers, and add corresponding hooks in struct drm_crtc_funcs. These
hooks take struct drm_crtc pointer as argument, and will be called by
core vblank handling code for DRIVER_MODESET drivers.
The new hooks get plugged into core by adding wrapper functions for
vblank handling code. The .get_vblank_counter hook is effectively
optional, as we provide drm_vblank_no_hw_counter() as the default
fallback in the wrapper function.

Every time I have lurked into vblank code I was wondering why it is not
a part of crtc, thanks for clearing it up.
Small comment below, anyway:

After converting all modeset drivers dev->driver->get_vblank_counter
could be called only for non-modeset drivers, ie 'else' can be put
before last if, the same for two other callbacks.

Shawn converted a lot of drivers, but not yet all of them. There's a lot
more kms drivers, so probably will take some time until we can do this.
But a good long-term goal indeed.

Probably should be added to that new TODO list thing... =)

From: Shawn Guo <shawn.guo@linaro.org>
Core code already makes drm_driver.get_vblank_counter hook optional by
letting drm_vblank_no_hw_counter be the default implementation for the
function hook. So the drm_vblank_no_hw_counter assignment in the driver
code becomes redundant and can be removed now.

On an unrelated note, for security reasons we should try to make the driver
structure static, or at least move ops to a static structure.
Anyway, for this patch,

ITYM "const" not "static".
"static" doesn't get you anything from a security point of view. "const"
gets you write protection, so code can't modify the function pointers.

That's what I meant, sorry. My brain-fingers link seems to be have a high
noise level this week.

We can't easily do that for struct drm_driver at the moment because some
fields end up being modified at runtime. I suppose we could move some of
those fields over to struct drm_device, which, in many cases, would make
more sense anyway.
What i915 is currently doing is probably fine for all existing cases,
but it sets a bad example for other drivers that may end up having to
drive multiple devices with one driver, so modifying the global driver
is likely going to break things.

Thanks. Missing this hook was actually a problem in vc4 for a while, so
it's nice to have sensible defaults. For vc4:

The function drm_vblank_no_hw_counter() is now only used in core vblank
wrapper code. Let's unexport it by making it a static function.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead. As the result,
functions armada_drm_crtc_enable[disable]_irq() can be static, although
they are moved around a bit to save forward declaration.
The armada_crtc pointer array in struct armada_private is still kept in
there, because armada_debugfs.c still have reference to it.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
As the result, exynos_drm_crtc_enable[disable]_vblank() become static
functions. They are moved around a bit to save forward declaration
though. Also while at it, we move one step further to kill
exynos_drm_crtc_from_pipe() completely by updating hdmi_bind() a bit.

From: Shawn Guo <shawn.guo@linaro.org>
The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

From: Shawn Guo <shawn.guo@linaro.org>
With the vblank hooks in struct drm_crtc_funcs, we do not need to
maintain the CRTC specific vblank callbacks with struct
imx_drm_crtc_helper_funcs any more. By moving the stuff that we
currently do in imx_drm_add_crtc(), like of_node setting and
drm_crtc_helper_add()/drm_crtc_init_with_planes() invoking, we can kill
things like struct imx_drm_crtc, imx_drm_crtc_helper_funcs and related
functions completely.
Functions ipu_enable_vblank() and ipu_disable_vblank() are moved around
without changes, only for saving the forward declarations.

Thanks for removing the imx_drm_crtc indirection.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

From: Shawn Guo <shawn.guo@linaro.org>
The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
As the result, shmob_drm_crtc_enable_vblank() becomes a static function,
although it gets moved around a bit to save forward declaration.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
As the result, the wrapper functions tegra_drm_xxx get killed
completely, and tegra_dc_xxx are filled into struct drm_crtc_funcs as
vblank hooks directly.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
While at it, the 'return' of .disable_vblank is dropped to fix the
following checkpatch warning.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
The functions are moved around to save forward declaration.

Thanks for the series. I've attached a patch for omapdrm, in case you're
sending v4 and want to include it in the series.

Subject: [PATCH] drm/omap: use vblank hooks in struct drm_crtc_funcs
The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

Tomi's ack.

Hi Shawn,
Thanks for the cleanup, it looks great! Let's soak this on the list until next
week, if there are no objections from driver maintainers, I'll merge it to
-misc.

As suggested by Daniel, I pushed another 11 patches which have already
received Reviewed-by or Acked-by to branch drm-misc-next. That leaves
the last 3 flowing around, i.e. kirin, mediatek and qxl.
So the drm-misc committer flow works for me \o/
