The mode_valid() callbacks of drm_encoder, drm_crtc and drm_bridge
accept const struct drm_display_mode argument. Change the mode_valid
callback of drm_encoder_slave to also accept const argument.

Make amdgpu_dm_connector_mode_valid() duplicate the mode during the
test rather than modifying the passed mode. This is a preparation to
converting the mode_valid() callback of drm_connector to take a const
struct drm_display_mode argument.

The mode_valid() callbacks of drm_encoder, drm_crtc and drm_bridge
take a const struct drm_display_mode argument. Change the mode_valid_ctx
callback of drm_connector to also take a const argument.

I cannot find these in drm-misc or drm-next, but they are in drm-tip?
The last one due to commit 2bdc721917cf141f ("Merge remote-tracking
branch 'drm-misc/drm-misc-next' into drm-tip").
What am I missing?
Thanks!
P.S. Sima: noticed while resolving a merge conflict using drm-tip. Thx!

These are in drm-misc/drm-misc-next, the commit IDs are a part of the
Git history.

It might be some kind of misinteraction between drm-misc-next vs
drm-misc-next-fixes vs merge window. Let me recheck dim rebuild-tip.

I indeed see the commit in
https://gitlab.freedesktop.org/drm/misc/kernel/-/blob/drm-misc-next/include/drm/drm_modeset_helper_vtables.h?ref_type=heads
[diving deeper]
So I missed the change from the for-linux-next to the drm-misc-next
branch. Hence I fetched only the former, and was using a stale
version of the latter.
Apparently Stephen is also using the old branches for linux-next:
drm-misc-fixes git
https://gitlab.freedesktop.org/drm/misc/kernel.git#for-linux-next-fixes
drm-misc git
https://gitlab.freedesktop.org/drm/misc/kernel.git#for-linux-next
I believe the latter should be drm-misc-next.
Should the former be drm-misc-fixes or drm-misc-next-fixes? Or both?
Thanks!
Gr{oetje,eeting}s,
Geert

No. Both branches are correct. This is how the drm-misc tree managed
development process: during the merge window (and several preceeding
weeks) the drm-misc-next branch is open for the commits. However those
commits are not targeted the forthcoming -rc1. Thus the for-linux-next
branch is diverted to point to drm-misc-next-fixes. This is all being by
the dim tool.
Respective mode_valid changes were applied too late in the cycle, so
they are not going to land into 6.14-rc1 (and are not a part of the
for-linux-next branch). Once 6.14-rc1 is released and we start working
towards 6.15, for-linux-next will again point to drm-misc-next.
