This needs work, and hey, if someone wants to spend the time to get things working, great. Let's move on it and modernize the target. problem 2. lack of development hardware in the FreeBSD project. I'm not asking for people to buy the FreeBSD project 10-15 year old sparc hardware and send it to us. We don't want it. If there is a push to modernize support for Sparc machines, we can talk about aquiring new machines and racking them up as reference boxes. If there are people interested in modernizing CPU support, by all means, move forward and do it. Don't let me stop you. sean p.s. if someone wants to take a stab at resurrecting qemu-user-static support for sparc64 so portmgr can build tier-2 packages like we do for mips/arm, please take a look at https://github.com/seanbruno/qemu-bsd-user/tree/bsd-user -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQF8BAEBCgBmBQJWPLb5XxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRCQUFENDYzMkU3MTIxREU4RDIwOTk3REQx MjAxRUZDQTFFNzI3RTY0AAoJEBIB78oecn5kaf4H/0C3rHmnFv3dtAyYwEzX4vLy erkQ1MD42czuLuSCcywO/P82u4ytV4Tsc/4A7uJvabQfanZF4s8rBPDdGoodIslO gZhvtMxhojueqtcvZjcLCBX5v3iu0aDL8w6PAafm0QvUUUNft42jbw+nD8l6xF+5 pPpKB0OK6KS3beuSqRGqfLIwAGSSXKjkktm3WaPEHu6N+WNCnA/kPMdLl2VTD7fU SOwkeoE5ItWgeHwQ1V6fr/kbRxJ+QYUxSeN5XeFzkQGM58GlkT2dhjL/y6feU6AO MlvOJhax03+uOGR4sxQOJ+F5ndWPbuZ+Lk64eVQiHoW6nbpKtuAwrAzehD9lg0w= =jW6R -----END PGP SIGNATURE-----
