[PATCH v5 00/12] Enable GPU switching on pre-retina MacBook Pro
...ew patch [01/12]: vga_switcheroo handler flags
Alex Deucher asked if this series might regress on non-Apple laptops.
To address this concern, I let handlers declare their capabilities in
a bitmask. DRM drivers call drm_get_edid_switcheroo() only if the
handler has set the VGA_SWITCHEROO_CAN_SWITCH_DDC flag.
Currently just one other flag is defined which is used on retinas.
* Changed patch [02/12]: vga_switcheroo DDC locking
Rename ddc_lock to mux_hw_lock, suggested by Daniel Vetter.
* New patch [03/12]: track switch state of apple-gmux
Fixes a bug in previous versions of this series whic...

[PATCH v5 01/12] vga_switcheroo: Add handler flags infrastructure
...t
with these pre-calibrated values (DisplayPort specification v1.1a,
section 2.5.3.3). Clients need a way to recognize such a situation.
The flags for the radeon_atpx_handler and amdgpu_atpx_handler are
initially set to 0, this can later on be amended with
handler_flags |= VGA_SWITCHEROO_CAN_SWITCH_DDC;
when a ->switch_ddc callback is added.
