I had heard rumours it was being done, but alas I cannot confirm it (though doubtless someone else more authorative will - I beleive it may be needed in the grand scheme of things as it's quite common as an embedded SCSI controller on Laptops)... > Already, I am running an "out-of-focus" kernel with a current > (as of a couple weeks ago -- I forget the date of the last makeworld) > system, meaning I can't load any `lkm's (including the screen saver) due to > problems with an undefined symbol `_biovidsw'. This is a problem I can relate to - I've 'frozen' my system (i.e. not build the world on it) for quite a while now... I was waiting for the dust to settle re. CAM, ELF etc. - though it's really starting to hurt... Unfortunately I didn't keep a copy of the last /usr/src I used to build the world, so the copy I have on the system is now newer than the 'system'... In short I can't build Kernels, I can't build LKM's - and I'm finally taking the plunge and backing everything up and bringing the system up to date this weekend... > Also, can anyone point me to a good introduction or > summary as to what CAM is (I know it stands for "Common Access Method"), > what its "advantages" are to the old way, and why it's worth putting us > `aic'ers in limbo over this? Thanks. CAM is certainly the way forward - it has better error recovery, it is apparently 'cleaner' than the current FreeBSD SCSI code - and if you want more details try: http://www.freebsd.org/~gibbs/ (Actually looking at that page it's very detailed... I just hope it's up to date ;-) Regards, Karl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
