+Subject: [PATCH xserver v3] autobind GPUs to the screen
+
+This is a modified version of a patch we've been carry-ing in Fedora and
+RHEL for years now. This patch automatically adds secondary GPUs to the
+master as output sink / offload source making e.g. the use of
+slave-outputs just work, with requiring the user to manually run
+"xrandr --setprovideroutputsource" before he can hookup an external
+monitor to his hybrid graphics laptop.
+
+There is one problem with this patch, which is why it was not upstreamed
+before. What to do when a secondary GPU gets detected really is a policy
+decission (e.g. one may want to autobind PCI GPUs but not USB ones) and
+as such should be under control of the Desktop Environment.
+
+Unconditionally adding autobinding support to the xserver will result
+in races between the DE dealing with the hotplug of a secondary GPU
+and the server itself dealing with it.
+
+However we've waited for years for any Desktop Environments to actually
+start doing some sort of autoconfiguration of secondary GPUs and there
+is still not a single DE dealing with this, so I believe that it is
+time to upstream this now.
+
+To avoid potential future problems if any DEs get support for doing
+secondary GPU configuration themselves, the new autobind functionality
+is made optional. Since no DEs currently support doing this themselves it
+is enabled by default. When DEs grow support for doing this themselves
+they can disable the servers autobinding through the servers cmdline or a
+xorg.conf snippet.

+Changes in v2:
+-Make the default enabled instead of installing a xorg.conf
+ snippet which enables it unconditionally
+Changes in v3:
+-Handle GPUScreen autoconfig in randr/rrprovider.c, looking at
+ rrScrPriv->provider, rather then in hw/xfree86/modes/xf86Crtc.c
+ looking at xf86CrtcConfig->provider. This fixes the autoconfig not
+ working with the nvidia binary driver
