Bit 11 of MI_MODE is "Invalidate UHPTR enable". Bit 12 of MI_MODE is "MI_FLUSH Enable" And, yet, in i915_reg.h: #define MI_MODE 0x0209c # define VS_TIMER_DISPATCH (1 << 6) # define MI_FLUSH_ENABLE (1 << 11) Are we off-by-one on MI_FLUSH_ENABLE? Seems like this would cause serious problems... =2D-=20 keith.packard@intel.com --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUBTtRH5DYtFsjWk68qAQj+gRAA0oNPkL4R9eChNG18Ma4kSDn0NsNf2U9d cRDIsTDvLHTsHrUFL6ySJOalirzkwezuH9mWsQIzOSJ2+R+o4OzTfb7kvdLbrTTa bZXOseRWWw+X8g1G86Dm0EGxg1Ob0tWkHvomwWlSF+IkH5K136a9h0Yo2cnTjXmp a6CwbuYC0mswvoBsgk3NFHEB7pZxFK4PkID7U7BJtuWhvq8H8FWwa23X22uky4eA r8N/JSfUYERa4vHV3YzXzhaQ6bZWHb7tEG+GtlVheVc9n9YjHc0nzCc56hj6TR6Y ZKR82zr6YzLcbxelDGNyvPcx+c2zoRQe/qzXq7LvN3iiHBRK8/grdL0qbOnvHV3z ErA8617GwlxnwfX5T7SSa4zWUU2G5nyMqyNfool/VUGs2ixGjk4m260Ekz2FwIEh 0ihvO8xcVML3tvOM/yzKPciOFqJCRXmHKOoCIU6oL9Tv6j9b1mr2BZ3OO27seIw3 PfSF2gbOKmjOqzqDr6f3gvHypFuprNbtrwNwF3W2L+rfj5vhJ+fkVCDE8Uk3auwG /5CahPYoGfDeb+7qXIYGfc9ZOepKXdEBIDQiRFHKOp2mBylWqTrL+3LDK1Thprtf O1+AsWpDSGJFPgkiorJmj28rQZZZQyTp9KbJZgEo7lFp9MNfqJghfyQI7+NpEBZk XaTtEGznskk= =+XdV -----END PGP SIGNATURE----- --=-=-=-- --===============1380770487== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx --===============1380770487==--
