Muxing it into addfb2 seemed unnatural, but I'm not opposed to someone adding one. I just think userspace will have to use one or the other depending on whether all the data is packed into a single bo or not. --=20 Jesse Barnes, Intel Open Source Technology Center --Sig_/dp2PbO8zwBuugNwL9tqkh5x Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAEBAgAGBQJOsugPAAoJEIEoDkX4Qk9hhKQP/04bZ5l4jy5ogAfGyINYCTW4 k1Os5V1SJOcWdq3o9tiedzDdEWxqdXvcdydGgvLe4ti08qmcVMYFviDT4KDeS0nk Evt1WQumLPr20yT6Wognzxg+6jBfQI/MdHSc0k8Syz6yotKIOozPXMPOUWAvOusP WZbOxPYH3X7XIhzHlbnnn7weeTo+cCGl6xyha5XBT1LssmVA8EWNaSOd9tb0ObD1 UgE4rmYSaR7IdrHC3NrphX6u6CW16THr6JtlYVwaJrPOE9HfjyGCCJRQnJ3NWu3/ /y2VNe3b/BiEOHeHQ0M9gmuZRjTi28+xS6HFWk8uUPyA0uDpAeNi2+zkrtDfQA8v +uQNB2IPOCxPZgfFd3En7NUhikiwSjS12C3r+YN9RfgjM2OHjh0Q8ojORDcJHTkL kXuqwzOnwV93RpXCRlNFzMFI445z+QP0URLKkfihR1xBt7b98TRBzKJinIWY+OCJ a+rBnTHSyHneYqaMthl7m0wtWeyXFInmQJFAmSMk7BxQ1howFpCANU9BerIYFB8m NFmzqWD4N4XHcgIbVKqH5vzE9echzVg3yJc4Mwa6jjG1fw/vofrBp9Ek4dH1wCvL BLVnlhkjsbtJO8goku3ZcgGk7TA3oG9gzl7d2M22DRbT/ZWYWMkBnVU8aJ3eqXWP iY4BLLL2mlGch5U0atsG =Z1yb -----END PGP SIGNATURE----- --Sig_/dp2PbO8zwBuugNwL9tqkh5x-- --===============1083903785== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel --===============1083903785==--
