Merge tag 'drm-next-2024-09-19' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie: "This adds a couple of patches outside the drm core, all should be acked appropriately, the string and pstore ones are the main ones that come to mind. Otherwise it's the usual drivers, xe is getting enabled by default on some new hardware, we've changed the device number handling to allow more devices, and we added some optional rust code to create QR codes in the panic handler, an idea first suggested I think 10 years ago :-) string: - add mem_is_zero() core: - support more device numbers - use XArray for minor ids - add backlight constants - Split dma fence array creation into alloc and arm fbdev: - remove usage of old fbdev hooks kms: -

As of commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in
drm_panel"), we have a check in the drm_panel core to make sure nobody
double-calls prepare/enable/disable/unprepare. Eventually that should probably
-be turned into a WARN_ON() or somehow made louder, but right now we actually
-expect it to trigger and so we don't want it to be too loud.
-
-Specifically, that warning will trigger for panel-edp and panel-simple at
-shutdown time because those panels hardcode a call to drm_panel_disable()
-and drm_panel_unprepare() at shutdown and remove time that they call regardless
-of panel state. On systems with a properly coded DRM modeset driver that
-calls drm_atomic_helper_shutdown() this is pretty much guaranteed to cause
-the warning to fire.
-
-Unfortunately we can't safely remove the calls in panel-edp and panel-simple
-until we're sure that all DRM modeset drivers that are used with those panels
-properly call drm_atomic_helper_shutdown(). This TODO item is to validate
-that all DRM modeset drivers used with panel-edp and panel-simple properly
-call drm_atomic_helper_shutdown() and then remove the calls to
-disable/unprepare from those panels. Alternatively, this TODO item could be
-removed by convincing stakeholders that those calls are fine and downgrading
-the error message in drm_panel_disable() / drm_panel_unprepare() to a
-debug-level message.
+be turned into a WARN_ON() or somehow made louder.
+
+At the moment, we expect that we may still encounter the warnings in the
+drm_panel core when using panel-simple and panel-edp. Since those panel
+drivers are used with a lot of different DRM modeset drivers they still
+make an extra effort to disable/unprepare the panel themsevles at shutdown
+time. Specifically we could still encounter those warnings if the panel
+driver gets shutdown() _before_ the DRM modeset driver and the DRM modeset
+driver properly calls drm_atomic_helper_shutdown() in its own shutdown()
+callback. Warnings could be avoided in such a case by using something like
+device links to ensure that the panel gets shutdown() after the DRM modeset
+driver.
+
+Once all DRM modeset drivers are known to shutdown properly, the extra
+calls to disable/unprepare in remove/shutdown in panel-simple and panel-edp
+should be removed and this TODO item marked complete.
