[-- Attachment #1 --] What requirements still need to be met before the HPS USB stack is committed to CURRENT? I understand that introducing a major sub-system change so close the start of a release cycle can be very disruptive. My main concern is that the RELENG_7 branch will be arriving in the next couple months and imp@ mentioned in the (Re: UMASS pbm at startup) thread that RELENG_7 might not see the new stack. This means that we'll have to wait until an 8.x release (2009?) until we see the new stack in a stock install. Also the current stack will then need to be supported during the entire life of RELENG_7 which will probably into at least late 2010. From here on out the limitations of the current USB stack not being MPSAFE will only become more apparent with more systems shipping with multiple processors. Such as not allow CPUs to drop to C3 when USB is loaded, performance issues, and various HID parsing problems. With all that said what would be needed so that we could see the new stack in 7.1 eventhough 7.0 would have the old stack? Though this does seem to be asking for a lot of trouble since it would be a STABLE branch. -- Anish Mistry amistry@am-productions.biz AM Productions http://am-productions.biz/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.3 (FreeBSD) iD8DBQBGWyscxqA5ziudZT0RAgfxAJ4/Js04Ei3dd4HD4pDoEjmiFlw89wCgpDcH g1aTkhtOfPN72eAVvGGY/w0= =tmNL -----END PGP SIGNATURE-----
