[Nouveau] [PATCH v3 00/22] drm: Clean up VBLANK callbacks in struct drm_driver
VBLANK handlers in struct drm_driver are deprecated. Only legacy,
non-KMS drivers are supposed to used them. DRM drivers with kernel
modesetting are supposed to use VBLANK callbacks of the CRTC
infrastructure.
This patchset converts all DRM drivers to CRTC VBLANK callbacks and
cleans up struct drm_driver. The remaining VBLANK callbacks in struct
drm_driver are only used by legacy drivers.
Patch 1 removes an additional setup step of vblank_disable_immediate
in struct drm_device. This simplifies the integration of CRTC VBLANK
callbacks in patch 3. If necessary, a future patch could move
vblank_disable_immedate to struct drm_crtc, so that high-precision
VBLANKs could be enabled on a per-CRTC basis.
Patches 2 and 3 prepare the DRM infrastructure. These patches add
get_scanout_position() to struct drm_crtc_helper_funcs,
get_vblank_timestamp() to struct drm_crtc_funcs, and add helpers for
the new interfaces.
Patches 4 to 20 convert drivers over.
In patch 21, all VBLANK callbacks are removed from struct drm_driver,
except for get_vblank_counter(), enable_vblank(), and disable_vblank().
These interfaces are moved to the legacy section at the end of the
structure. Old helper code is now unused and being removed as well.
Finally, patch 22 removes an older version of get_scanout_position()
from the VBLANK interface.
To cover all affected drivers, I build the patchset in x86, x86-64,
arm and aarch64. I smoke-tested amdgpu, gma500, i915, radeon and vc4 on
respective hardware.
v3:
* refactor drm_calc_vbltimestamp_from_scanout_pos to share code
with new helper (Villa, Jani)
* do more checks for crtc != NULL to cover non-KMS drivers (Ville)
* add function typedefs for readability (Ville)
v2:
* reorder patches so the i915 can be converted without duplicating
helper code.
* merged cleanup patches
* changed VBLANK function signatures in amdgpu (Alex)

[Nouveau] [PATCH v3 01/22] drm: Remove internal setup of struct drm_device.vblank_disable_immediate
VBLANK interrupts can be disabled immediately or with a delay, where the
latter is the default. The former option can be selected by setting
get_vblank_timestamp and enabling vblank_disable_immediate in struct
drm_device. Simplify the code in preparation of the removal of struct
drm_device.get_vblank_timestamp.

[Nouveau] [PATCH v3 02/22] drm: Add get_scanout_position() to struct drm_crtc_helper_funcs
The new callback get_scanout_position() reads the current location
of the scanout process. The operation is currently located in struct
drm_driver, but really belongs to the CRTC. Drivers will be converted
in separate patches.
To help with the conversion, the timestamp calculation has been
moved from drm_calc_vbltimestamp_from_scanoutpos() to
drm_crtc_vblank_helper_get_vblank_timestamp_internal(). The helper
function supports the new and old interface of get_scanout_position().
drm_calc_vbltimestamp_from_scanoutpos() remains as a wrapper around
the new function.
Callback functions return the scanout position from the CRTC. The
legacy version of the interface receives the device and pipe index,
the modern version receives a pointer to the CRTC. We keep the
legacy version until all drivers have been converted.
v3:
* refactor drm_calc_vbltimestamp_from_scanoutpos() to minimize
code duplication
* define types for get_scanout_position() callbacks
v2:
* fix logical op in drm_calc_vbltimestamp_from_scanoutpos()

[Nouveau] [PATCH v3 03/22] drm: Add get_vblank_timestamp() to struct drm_crtc_funcs
The callback get_vblank_timestamp() is currently located in struct
drm_driver, but really belongs into struct drm_crtc_funcs. Add an
equivalent there. Driver will be converted in separate patches.
The default implementation is drm_calc_vbltimestamp_from_scanoutpos().
The patch adds drm_crtc_vblank_helper_get_vblank_timestamp(), which is
an implementation for the CRTC callback.
v3:
* use refactored timestamp calculation to minimize duplicated code
* do more checks for crtc != NULL to support legacy drivers
v2:
* rename helper to drm_crtc_vblank_helper_get_vblank_timestamp()
* replace drm_calc_vbltimestamp_from_scanoutpos() with
drm_crtc_vblank_helper_get_vblank_timestamp() in docs

[Nouveau] [PATCH v3 07/22] drm/i915: Convert to CRTC VBLANK callbacks
VBLANK callbacks in struct drm_driver are deprecated in favor of their
equivalents in struct drm_crtc_funcs. Convert i915 over.
The callback struct drm_driver.get_scanout_position() is deprecated
in favor of struct drm_crtc_helper_funcs.get_scanout_position().
i915 doesn't use CRTC helpers. Instead pass i915's implementation of
get_scanout_position() to DRM core's
drm_crtc_vblank_helper_get_vblank_timestamp_internal().
v3:
* rename dcrtc to _crtc
* use intel_ prefix for i915_crtc_get_vblank_timestamp()
* update for drm_crtc_vblank_helper_get_vblank_timestamp_internal()
v2:
* use DRM's implementation of get_vblank_timestamp()
* simplify function names

[Nouveau] [PATCH v3 08/22] drm/nouveau: Convert to struct drm_crtc_helper_funcs.get_scanout_position()
The callback struct drm_driver.get_scanout_position() is deprecated in

[Nouveau] [PATCH v3 21/22] drm: Clean-up VBLANK-related callbacks in struct drm_driver
All non-legacy users of VBLANK functions in struct drm_driver have been
converted to use the respective interfaces in struct drm_crtc_funcs. The
remaining users of VBLANK callbacks in struct drm_driver are legacy drivers
with userspace modesetting.
All users of struct drm_driver.get_scanout_position() have been
converted to the respective CRTC helper function. Remove the callback
from struct drm_driver.
There are no users left of get_vblank_timestamp(), so the callback is
being removed. The other VBLANK callbacks are being moved to the legacy
section at the end of struct drm_driver.
Also removed is drm_calc_vbltimestamp_from_scanoutpos(). Callers of this
function have been converted to use the CRTC instead.
v2:
* merge with removal of struct drm_driver.get_scanout_position()
* remove drm_calc_vbltimestamp_from_scanoutpos()

[Nouveau] [PATCH v3 22/22] drm: Remove legacy version of get_scanout_position()
The legacy version of get_scanout_position() was only useful while
drivers still used drm_driver.get_scanout_position(). With no such
drivers left, the related typedef and code can be removed
