It's time for MIPS to go. It's never been broadly maintained and the codebase has always been a bit odd contributing to the maintenance burden of the project as a whole. Over the last decade, most mips64 maintenance has been by the CHERI project at SRI International and the University of Cambridge. We published some well-cited papers and it has had major impacts on Arm's Morello prototype architecture. However, over the past three-ish years we've moved our work to RISC-V and Morello. At this point we have no active projects that depend on MIPS and we'll likely respond to future significant merge conflicts in the sys/mips tree by removing our local changes. -- Brooks --3siQDZowHQqNOShm Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJhTPDgAAoJEKzQXbSebgfAZicH/2rBuIBkV3uyjxfNoOh3hUM0 yh6NN9peQ1LJsEnyjy5JC7GHbc6rcTvdK8LlA4CIXdboSpItcs0g28A02OR3ktNV +8wgEbZuglbUYHt9rVBIEIn+ClLX9/hRffdZBqVqcU7Klx3eh1Fc3LnSfrQ4aAm/ XRx9r3DC6AfD6fnFE8WtD2raBrIlShANnkeBY3Y8qJNHOw8urUN+VUBFVZ8ZSSDF hrGAi+glh7Y8wtMbeHdCyAQKnC6ep08+ca2JzX4SR/RMECVidUfSs4cPk0pJP88U tKrOBHMBd97E9nCVuwMv7+Aa5IrmrXAJRogfKdkYu1xDUPAGpHWBSMK5zYmIQaE= =2zBc -----END PGP SIGNATURE----- --3siQDZowHQqNOShm--
