[Intel-gfx] [PATCH v2 00/22] Enable gpu switching on the MacBook Pro
...enefit is compared to just keeping the
connector in the mode configuration, but with status disconnected,
and reprobing it when the ->output_poll_changed callback gets invoked?
Because that's what nouveau already does, and what I've changed i915
to do with patch 13.
vga_switcheroo calls drm_kms_helper_hotplug_event() when the handler
registers (patch 11), which will invoke ->output_poll_changed.
So we're talking about the Official DRM Callback [tm] to probe
outputs, not "hand-rolling depency avoidance". :-)

[PATCH 0/2] Fix connector probing deadlocks from RPM bugs
This is a trimmed down version of
https://patchwork.freedesktop.org/series/46637/
with all of the review comments addressed.
The last version of this series had fixes for the i2c and DP aux busses
to ensure that the GPU would be turned on whenever anything tried to
access the i2c/aux busses. Unfortunately: one of the fixes apparently
contained some very incorrect usage of Linux's runtime PM
