Changes to allow vga-switcheroo to switch the mux while modesetting clients remain active. There is existing support for switching the mux without checking can_switch; however, this support also does not reprobe after the mux switch is complete. This patch series adds a new type of switch event which switches immediately while still calling client driver callbacks, and updates the i915 DRM-KMS driver to reprobe eDP outputs after switching the mux to an i915-driven GPU, and to avoid using eDP links (which i915 always assumes to be connected) while the mux is switched away. Daniel Dadap (6): vga-switcheroo: add new "immediate" switch event type vga-switcheroo: Add a way to test for the active client vga-switcheroo: notify clients of pending/completed switch events i915: implement vga-switcheroo reprobe() callback i915: fail atomic commit when muxed away i915: bail out of eDP link training while mux-switched away drivers/gpu/drm/i915/display/intel_display.c | 7 + .../drm/i915/display/intel_dp_link_training.c | 9 ++ drivers/gpu/drm/i915/i915_switcheroo.c | 27 +++- drivers/gpu/vga/vga_switcheroo.c | 153 ++++++++++++++---- include/linux/vga_switcheroo.h | 20 +++ 5 files changed, 185 insertions(+), 31 deletions(-) -- 2.18.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
