Hi FreeBSD hackers, +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ No opinions on arch@, so i will try at hackers@, since here is bigger audience :) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
at first I want to say this: :) WARNING: FOLLOWING DEVCTL PATCH MAY EASILY PANIC YOUR SYSTEM, PLEASE DO NOT TRY IT ON PRODUCTION SERVERS AND TRY IT WITH FILESYSTEMS MOUNTED AS READONLY :))))) So I introduce two patches first one [1] used to migrate from static_hints or hints in the static_kenv to dynamic hints. sysctl kern.hintmode=2 will copy hints from static hints or from static kenv and put it into dynamic kenv. Those will allow to manipulate hints values and attach hinted devices with devctl tool. Second [2] allow attach/detach devices with userland tool devctl. devctl tool allow add and initialize new devices which is not able to be auto-enumerating, such a hinted devices. Both designed to have ability update EEPROM items in runtime, since some device can't work in mode when it accessible like a EEPROM chip. Example: # sysctl kern.hintmode=2 # kenv hint.mx25l.0.at="spibus0" # kenv hint.mx25l.0.cs=0 # kenv hint.mx25l.0.chipname="at25128" # devctl hinted spibus 0 mx25l 0 mx25l0: <M25Pxx Flash Family> at cs 0 mode 0 on spibus0 mx25l0: at25128, sector 64 bytes, 256 sectors GEOM: new disk flash/spi0 Someone may found it also useful for testing device attach/detach code (memory leaks, resource allocation, etc). So, say me please your opinion. 1. http://my.ddteam.net/files/2012-01-31.to_dynamic_hints.patch 2. http://my.ddteam.net/files/2012-01-31.devctl2.patch WBW -- Aleksandr Rybalko <r...@ddteam.net> _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
