A couple of things I'll add: There are a few of us who have been running this code, and while it's not bug free or a complete port, we need to have it in -current so that changes to -current take sun4v into account. The FreeBSD Foundation has sourced 2 T1000 boxes which will allow FreeBSD developers access to the platform. As a developer group we need to take advantage of that investment. There is work to do to implement floating point support. When self-hosting on local disk on the T2000 (with SATA drives) there is a bug which causes a processor to go off into the weeds. To debug this, kmacy needs someone to donate another SATA drive. Sun hasn't been responsive to his request for one. 8-( Can anyone help with that? There is a binutils update required to -current before sun4v will build out of the box. It seems we have a problem being able to make non-vendor branch commits to GNU tools just to support building a new arch. This is a bit disappointing. Surely we should be able to handle taking one or two files off the vendor branch on the odd occasion we add a significant new arch! Thread support is a problem because with KSE in the kernel, signal delivery on sun4v is a problem. In fact it is such a problem that a simple buildworld won't complete. When the T1000s are added to the FreeBSD cluster, there is work required by KSE folks to fix those problems or a non-KSE solution will be required. This is a major problem. My personal interest in sun4v is based on the fact that Sun Microsystems sent me a T2000 with all the bells and whistles in response to my work on DTrace for FreeBSD. In return I would like to see sun4v supported nicely in FreeBSD. One good turn deserves another. Sun has been generous in their support for FreeBSD, so we should return the favour. -- John Birrell _______________________________________________ cvs-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
