Threaded Input Is Back To Being Worked On For The X.Org Server
The design is to move the input event code off to its own thread rather than running on the same main thread as the X.Org Server. Keith Packard cleaned up the threaded input code and patches it for the xf86 and KDrive/FBDEV areas. As part of this work, Keith is proposing that SIGIO support be dropped from the X.Org Server, which will break DRI1 support. This patch series is part of the reason why DRI1 support was proposed to be killed off yesterday in the X.Org Server.
Keith Packard's revised threaded input code can be found via this patch series, which will hopefully get ready for the X.Org Server 1.19 release in 2016.
