Add ID_PATH to DRM devices for Xorg#4
Merged

Conversation
In create_drm_handler we add the PCI_ID udev property, but when using PRIME offloading Xorg wants to check ID_PATH in config_udev_odev_setup_attribs. This is necessary as part of the rube goldberg auto configuration of Nvidia Optimus machines. To get Xorg to play nice this change defines the ID_PATH property by querying the busid specified for the DRI node in question. This is done with the hw.dri.<cardnum>.busid sysctl. With this change we can define dynamic configs in xorg.conf.d and have X automatically use nvidia-drm.

Is there any way we can get a new release that includes this? This is needed for PRIME setups with nvidia-drm, so getting this in ports means one less thing for users to manually install when testing. |
