[PATCH 1/3] drm/atomic-helper: Extract drm_atomic_helper_calc_timestamping_constants()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Put the vblank timestamping constants update loop into its own
function. It has no business living inside
drm_atomic_helper_update_legacy_modeset_state() so we'll be wanting
to move it out entirely. As a first step we'll still call it
from drm_atomic_helper_update_legacy_modeset_state().

[PATCH 3/3] drm/i915: Drop the drm_atomic_helper_calc_timestamping_constants() call

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We update the timestamping constants per-crtc explicitly in
intel_crtc_update_active_timings(). Furtermore the helper will
use uapi.adjusted_mode whereas we want hw.adjusted_mode. Thus
let's drop the helper call an rely on what we already have in
intel_crtc_update_active_timings(). We can now also drop the
hw.adjusted_mode -> uapi.adjusted_mode copy hack that was added
to keep the helper from deriving the timestamping constants from
the wrong thing.

I think the kerneldoc for
drm_crtc_vblank_helper_get_vblank/_timestamp_internal (both of them) also
needs to be updated to mention the new function. With that fixed:

Does this fix some CI fail? I'd kinda expect/hope for that ...

Anyway looks like a good idea to not mess with the uapi state like this.

[PATCH 1/3] drm/atomic-helper: Extract drm_atomic_helper_calc_timestamping_constants()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Put the vblank timestamping constants update loop into its own
function. It has no business living inside
drm_atomic_helper_update_legacy_modeset_state() so we'll be wanting
to move it out entirely. As a first step we'll still call it
from drm_atomic_helper_update_legacy_modeset_state().
