I've already done the port for the Xorg server delivered in Solaris, just need to work on getting it released back to the open source version. Created attachment 3135 [details]
Server side of SolarisIA extension
Created attachment 3136 [details]
xc/include/extensions/interactive.h (shared by client-side and server-side)
Created attachment 3137 [details]
xc/include/extensions/interactiveCommon.h
Created attachment 3138 [details]
xc/lib/X11/XInteractive.c (client side of extension protocol)
Created attachment 3139 [details] [review] Patch to xc/lib/X11/OpenDis.c Okay - I think that's everything needed to use it in Xorg. The original Usenix paper describing the work that led to this is at: http://www.usenix.org/publications/library/proceedings/cinci93/full_papers/evans.txt A small bit of documentation on the IA priority control scheduler in Solaris that this uses can be found at: http://docs.sun.com/app/docs/doc/817-0689/6mgfkpd12?a=view#Inter-Active%20Class and of course in the Solaris kernel sources at: http://cvs.opensolaris.org/source/ Before we actually integrate it into Xorg though, I think we need to consider what to do about non-Solaris platforms, including: - abstracting out the priocntl/etc. calls into a wrapper which can be implemented differently for each OS - renaming it to something more generic and more descriptive than "SolarisIA" (In reply to comment #7) > Okay - I think that's everything needed to use it in Xorg.

And, of course, we have to fix our broken drivers not to gratuitously use CPU and thereby causing the X server to look like a CPU pig (which it is, at the moment). Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future. Alan, is this still relevant? (In reply to comment #10) > Alan, is this still relevant? We still ship this extension as a local patch to Xorg and still haven't gotten around to upstreaming it, so yes, I think it is. Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases. |
