Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference() and drm_*_unreference() helpers. drm_*_reference() and drm_*_unreference() functions are just compatibility alias for drm_*_get() and drm_*_put() and should not be used by new code.

The only thing modern drivers are supposed to do in lastclose is restore the fb emulation state. Which is entirely optional, and there's really no reason to do that. So restrict it to legacy drivers (where the driver cleanup essentially happens in lastclose). This will also allow us to share the unregister function with drm_dev_unplug().

So I think there's 3 cases: - Trying to unload the module. You can't do that while anyone has the fd still open, so lastclose is guaranteeed to run. - Forcefully unbinding the driver through sysfs. Not any better, since the can_switch stuff checks for the open count, and so will delay the delayed switch no matter what. - Actual hotremoval: a) not implemented since none of the drivers taking part in vgaswitcheroo correctly unplug the drm device and b) you can't hotremove a chip from a laptop. v2: Extend commit message with m-l discussion.

The only special case is nouveau which used one function for both pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2 vtables. But amounts to exactly the same. What is rather strange here is how few drivers set this up, I suspect the earlier patch to handle properties in the core did end up fixing a pile of possible issues. Signed-off-by:

The reason behind the original indirection through the helper functions was to allow existing drivers to overwrite how they handle properties. For example when a vendor-specific userspace had expectations that didn't match atomic. That seemed likely, since atomic is standardizing a _lot_ more of the behaviour of a kms driver. But 20 drivers later there's no such need at all. Worse, this forces all drivers to hook up the default behaviour, breaking userspace if they forget to do that. And it forces us to export a bunch of core function just for those helpers. And finally, these helpers are the last places using drm_atomic_legacy_backoff() and the implicit acquire_ctx. This patch here just implements the new behaviour and updates the docs. Follow-up patches will garbage-collect all the dead code. v2: Fixup docs even better! v3: Make it actually work ... v4: Drop the uses_atomic_modeset() checks from the previous patch again, since they're now moved up in the callchain.

Atomic drivers only use the property value store for immutable (i.e. can't be set by userspace, but the kernel can still adjust it) properties. The only tricky part is the removal of the update in drm_atomic_helper_update_legacy_modeset_state(). This was added in commit 8c10342c (tag: topic/drm-misc-2015-07-28) Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Mon Jul 27 13:24:29 2015 +0200 drm/atomic: Update legacy DPMS state during modesets, v3. by copying it from the i915 code, where it was originally added in commit 68d34720 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Sep 6 22:08:35 2012 +0200 drm/i915: update dpms property in set_mode for the legacy modeset code. The reason we needed this hack was that i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of the newer-ish drm_drv_uses_atomic_modeset(), which avoids such troubles. With the correct feature checks this isn't needed anymore at all. Also make sure that drivers don't accidentally get this wrong by making the exported version of drm_object_property_get_value() only work for legacy drivers. Only gma500 uses it anyway. v2: Fixup the uses_atomic_modeset() checks (Maarten) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by:

I want/need to rework the core property handling, and this hack is getting in the way. But since it's a non-standard propety only used by legacy userspace we know that this will only every be called from ioctl code.

Currently HDMI 2.0 PHYs do not have a default configuration function. As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D PHYs we can provide the same default configuration function for both and still let user overwrite this with custom configuration function if needed. If, for some reason, the PHY is custom or has a register different register layout then custom configuration function *must* be provided in order for the system to work correctly. As we prefer the pdata provided configuration function over the internal one this change will not make any impact in custom platforms. Signed-off-by:
